Effects of comorbidity on executive functions among children with ADHD, finding trends.

There is still no basic overview about the effect of various types of comorbidity in executive functions due to two main reasons: (1) the type and number of comorbidities in ADHD is significantly varied, (2) EFs are very diverse and have different neuropsychological properties. Our objective was to determine the effect of comorbid disorders (number and type) on the performance in a wide range (seven) of executive functions in a sample of children with ADHD. Fifty-five male children aged seven to nine years with ADHD were divided into six groups: G1 = ADHD only (ADHD-O), G1 = Oppositional defiant disorder (ODD), G3 = (anxiety/depressive disorder (ADD), G4 = ODD + ADD, G5 = ODD + learning disorder (LD), G6 = ODD + LD + conduct disorder (CD). The six groups exhibited different number of deficits in EFs; G1 showed only 1 deficit in contrast, G6 presented 11. Statistical analysis (ANOVA and logistic regression) identified three most affected EFs: Working memory, generation/classification of semantic categories, and inhibitory control. Alterations in EFs increased mainly in relation to the increase of the specific number and type of comorbidity. To date, no studies have addressed comorbidity from this perspective. A wide range approach of EF confirms the need to further study comorbidity in ADHD from a wide range/variety perspective and determine all possible combinations (number/type) to clarify its contribution to the complex neuropsychology functioning in ADHD.

Lesión hepática inducida por fármacos anestésicos / Liver injury induced by anesthetic drugs

Resumen: El daño hepático por medicamentos no es tan raro, su diagnóstico es por exclusión, en algunos casos puede inducir falla hepática aguda. Se realizó una revisión de la bibliografía de los medicamentos más utilizados en los procedimientos anestésicos y el riesgo que existe en estos medicamentos de desarrollar daño hepático por fármacos; los únicos medicamentos que tienen mayor riesgo de hepatotoxicidad son los inhalados halogenados, particularmente el halotano, ahora en desuso, el resto de los medicamentos son seguros.

Abstract: Liver damage by drugs is not so rare, its diagnosis is by exclusion, in some cases can induce acute liver failure. A review of the literature of the drugs most used in anesthetic procedures and the risk that exists of these drugs in the development of liver damage by drugs was carried out; the only drugs that have a higher risk of hepatotoxicity are halogenated inhaled ones, particularly halothane now in disuse, the rest of the drugs are safe.

Looking for factors affecting functioning in euthymic patients with bipolar I disorder: the importance of cognitive complaints and BDNF's Val66Met polymorphism.

INTRODUCTION: Functioning in Bipolar Disorder (BD) is affected in a substantial proportion of patients. The impact of demographic, clinical, cognitive, and genetic factors on functioning has been shown individually; however, as a complex phenomenon, a global approach to identify the most relevant as well as possible interactions is needed. METHODS: 102 patients with type I BD in euthymia were invited for evaluation of demographic, clinical, and cognitive characteristics as well as genotype for Val66Met polymorphism of BDNF gene to determine those associated with poor functioning according to the FAST scale cut-off score. Clinical evaluation included assessment of residual affective symptoms and anxiety. Cognitive evaluation included the COBRA scale, verbal memory, and executive functions testing. RESULTS: Residual depressive symptoms, anxiety, cognitive complaints and being a Met carrier were more frequent in the poor functioning group and were entered in a logistic regression model. Being a Met carrier (OR=4.46, CI=1.19-16.67) and cognitive complaints (OR=1.29, CI= 1.13-1.46) were the most important predictors of poor functioning in type I BD. LIMITATIONS: Cross-sectional study, with select population limiting generalizability of findings. CONCLUSIONS: A better understanding of underlying factors affecting cognition, including the possible involvement of BDNF Val66Met polymorphism, its systematic evaluation and a continued search for targeted treatment, along with recognition and attention of residual affective and anxious symptoms might improve psychosocial outcomes such as functioning in this population.

Intimate-partner violence and its relationship with substance consumption by Mexican men and women: National Survey on Addictions / Violencia de pareja y su relación con el consumo de sustancias en hombres y mujeres mexicanos: Encuesta Nacional de Adicciones

Abstract Introduction Research findings about intimate-partner violence (IPV) have focused mostly on women as victims of violence. Recent studies show the importance of violence inflicted by women towards men or between same-sex couples. Objective To estimate the prevalence of intimate-partner violence and its association with alcohol and drug consumption in a representative sample of men and women in Mexico through secondary data analysis. Method The data come from a representative sample who filled out the section on intimate-partner violence in the Mexican 2011 Encuesta Nacional de Adicciones (National Survey on Addictions). Results The prevalence of intimate-partner violence in the last year was 17.6% against women and 13.4% against men. If one of the two partners consumed substances, the risk that men and women would experience violence increased, and that risk was even greater if both consumed. Discussion and conclusion This is the first time violence against men was reported in a Mexican national study. The findings show that gender-based violence should also be considered a result of social and cultural violence.

Resumen Introducción Los hallazgos de investigación sobre la violencia de pareja se han centrado principalmente en las mujeres como víctimas de la violencia. Estudios recientes destacan también la importancia de la violencia infligida por las mujeres hacia los hombres o entre parejas del mismo sexo. Objetivo Estimar la prevalencia de la violencia de pareja y su asociación con el consumo de alcohol y drogas en una muestra representativa de hombres y mujeres en México mediante un análisis secundario de datos. Método Los datos provienen de la Encuesta Nacional de Adicciones de México 2011, específicamente de una muestra representativa que contestó la sección sobre violencia de pareja. Resultados La prevalencia de violencia de pareja en el último año fue de 17.6% hacia las mujeres y de 13.4% hacia los hombres. Si uno de los dos integrantes de la pareja consumía sustancias, aumentaba el riesgo de que hombres o mujeres experimentaran violencia y ese riesgo era aún mayor si ambos consumían. Discusión y conclusión Esta es la primera vez que se reporta la violencia hacia los hombres en un estudio nacional mexicano. Los resultados muestran que la violencia de género también debe considerarse como resultado de la violencia social y cultural.

Depressive disorder and psychosocial indicators in high school and college students from Mexico City: data from two censuses / Trastorno depresivo e indicadores psicosociales en estudiantes de bachillerato y de licenciatura de la Ciudad de México: datos de dos censos

Abstract Introduction Almost 5% of the Mexican general population (18-65 years old) has suffered depression once in their lives, and 2% of them more than once without receiving treatment. Objetive To measure the prevalence of depressive disorder and to calculate its relationship with psychosocial indicators. Method Data were collected through two censuses with high school and college students from a university in Mexico City (n = 116 214). Participants completed the CES-D and other scales. Multivariate logistic regression models were used. Results The prevalence of depressive disorder was 16%. Predictors of depressive disorder were: having suffered psychological or sexual violence, having a family member who had been injured during an assault, history of depression in the family, poor quality in family and social relationships, among others. Discussion and conclusion The prevalence of depressive disorder increases with age. As prevention and treatment at an early age are essential, intervention and monitoring strategies must be created and systematized taking gender and other elements into account, such as the relationship with the parents, violence, and a history of depression in the family.

Resumen Introducción Casi el 5% de la población general de México (18-65 años) ha sufrido depresión una vez en su vida y 2% la ha sufrido más de una vez sin haber recibido tratamiento. Objetivo Medir la prevalencia del trastorno depresivo y calcular su relación con algunos indicadores psicosociales. Método Los datos fueron recolectados por medio de dos censos con estudiantes de bachillerato y de licenciatura en la Ciudad de México (n = 116 214). Los participantes completaron el CES-D y otras escalas. Se usaron modelos de regresión logística multivariable. Resultados La prevalencia del trastorno depresivo fue del 16%. Los predictores del trastorno depresivo fueron: haber sufrido violencia psicológica o sexual, tener un miembro de la familia que hubíera sido herido durante un asalto, antecedentes de depresión en la familia, mala calidad en las relaciones familiares y sociales, entre otros. Discusión y conclusión La prevalencia del trastorno depresivo aumenta con la edad. Como la prevención y el tratamiento a una edad temprana son esenciales, se deben crear y sistematizar estrategias de intervención y monitoreo que tomen en cuenta el género y otros elementos, como la relación con los padres, violencia e historia de depresión en la familia.

Internal consistency and confirmatory validity of the parenting practices inventory in a Mexican population sample / Consistencia interna y validez confirmatoria del inventario de prácticas de crianza en una muestra de población mexicana

Abstract Introduction Parenting practices refer to specific behaviours used by parents and caretakers of children to guide childhood development and socialization goals. These practices are associated with children's health, psychological, and physical development. Objective To determine the psychometric properties of the Parenting Practices Inventory (PPI) among a group of child caregivers in Mexico City. Method The PPI was applied to 443 caregivers of children and adolescents, who attended a general health care centre in Mexico City. For the psychometric evaluation of the instrument, the full distribution and discrimination of the items was analysed first. Then, the validity of the construct was tested through an exploratory factor analysis and a confirmatory analysis with structural equation modelling. Results The internal consistency of the PPI showed α = .867 and 41.25% of variance explained for all four dimensions of interest. The confirmatory factor analysis showed that the model had goodness of fit. It included twenty-four items with adequate consistency and validity indices. Discussion and conclusion The PPI is therefore a potentially useful psychometric measure for evaluating parenting practices among this type of population and could have major implications for the development of interventions and preventive programmes. It provides scientific bases for diagnostic decision-making and primary health care from the moment of initial contact to specialized medical care.

Resumen Introducción Las prácticas de crianza se refieren a comportamientos específicos utilizados por los padres y cuidadores de niños para guiar su desarrollo y metas de socialización infantil. Estas prácticas están asociadas con la salud, el desarrollo psicológico y físico de los niños. Objetivo Determinar las propiedades psicométricas del Inventario de Prácticas de Crianza (IPC) entre un grupo de cuidadores de niños en la Ciudad de México. Método El IPC se aplicó a 443 cuidadores de niños y adolescentes, que asistieron a consulta médica general en un Centro de salud en la Ciudad de México. Para la evaluación psicométrica del instrumento se analizó la distribución total y la discriminación de los reactivos. La validez de constructo se probó a través de análisis factorial exploratorio y análisis confirmatorio con modelos de ecuaciones estructurales. Resultados El IPC mostró α = .867 y 41.25% de la varianza explicada para las cuatro dimensiones de interés. El análisis factorial confirmatorio mostró que el modelo tuvo buena bondad de ajuste. Incluyó veinticuatro ítems con una consistencia e índices de validez adecuados. Discusión y conclusión El IPC es una medida psicométrica potencialmente útil para evaluar las prácticas de crianza en esta población y podría tener implicaciones importantes para el desarrollo de intervenciones y programas preventivos. Esto brinda bases científicas para la toma de decisiones en la atención primaria de la salud desde el momento del contacto inicial hasta la atención médica especializada en caso de ser requerida.

Psychometric properties and cross-cultural comparison of the cognitive complaints in bipolar disorder rating assessment (COBRA) in Mexican patients with bipolar disorder.

Bipolar Disorder (BD) is a serious and frequent mental health condition that is sometimes fatal. Several longitudinal studies have found an important correlation between cognition and functionality in BD. Despite the known importance of cognitive symptoms in BD, evaluation of cognitive deficits is not routinely done in clinical settings, as assessment is time-consuming and requires neuropsychological testing. The aim was to evaluate the psychometric properties of the subjective cognitive deficits in bipolar disorder (COBRA) rating scale in a Mexican sample of patients with BD and perform a cross-cultural comparison with the results obtained in other cultures. Ninety-two Healthy Subjects and 80 euthymic patients with BD were asked to complete the COBRA rating scale. The psychometric properties found in Mexican population show a good internal consistency and good discriminant validity with control subjects. Adequate congruence coefficients were obtained between the COBRA analyses in Mexican population and Spanish population and acceptable when compared to Japanese population. The COBRA scale is a brief and valid measure of cognitive complaints in BD for use in Mexican population.

Non-suicidal self-injuries in a sample of Mexican university students / Autolesiones no suicidas en una muestra de estudiantes universitarios mexicanos

Abstract Introduction Non-suicidal self-injuries (NSSI) are a worldwide health problem that affects principally young people, and can impact negatively the mental and physical health of those that self-injure. Objective To examine the frequency of NSSI in 564 undergraduate students (132 male, 432 female) from Mexico City and the association of NSSI with depressive symptoms, anxiety, impulsivity, self-efficacy, and emotion regulation. Method A convenience sample of 564 undergraduate students (aged 17-26 years) from eight universities in the Mexico City metropolitan area completed a survey in their classrooms. Results Of the total sample, 30.9% had experimented at some point in their lifetime with NSSI on one to four occasions, while 26.9% had recurrent NSSI (i.e., five or more occasions). Nearly eleven percent self-injured in the prior 12 months. The NSSI most often reported among those who self-injured was cutting oneself (48.0%). Recurrent self-injurers reported higher levels of depression and impulsivity, and less self-efficacy than those who had experimented with such behaviors or without any lifetime NSSI. While 54.4% perceived the need for professional help, only 18.1% sought professional services. Discussion and conclusion NSSI is a hidden problem in the college population in Mexico City which needs to be addressed by university administrators and mental health professionals. Depressive symptomatology, impulsivity, and self-efficacy are factors that should be considered when developing preventive intervention strategies.

Resumen Introducción Las autolesiones no suicidas (ANS) son un problema mundial de salud que afecta principalmente a jóvenes, y puede impactar de manera negativa la salud mental y física de la persona que se autolesiona. Objetivo Examinar la frecuencia de ANS en 564 estudiantes de licenciatura (132 hombres, 432 mujeres) de la Ciudad de México y la asociación de las ANS con síntomas depresivos, ansiedad, impulsividad, autoeficacia y regulación emocional. Método Una muestra de conveniencia de 564 estudiantes universitarios (edades 17-26 años) de ocho universidades del área metropolitana de la Ciudad de México completó una encuesta en sus salones de clases. Resultados Del total de la muestra, 30.9% se habían infligido ANS de manera experimental de una a cuatro ocasiones, mientras que 26.9% presentaron ANS recurrentes (cinco o más ocasiones) en algún momento en su vida. Casi once por ciento reportaron ANS en los 12 meses previos. Las ANS reportadas con mayor frecuencia entre aquellos que se autolesionaron fueron cortarse a sí mismos (48.0%). Las personas con autolesiones recurrentes reportaron mayores niveles de depresión e impulsividad, y menos autoeficacia que aquellas que habían experimentado con estos comportamientos o sin ninguna historia de ANS en su vida. Aunque 54.4% percibían la necesidad de atención, solo 18.1% buscaron servicios profesionales. Discusión y conclusión Las ANS son una problemática oculta en la población universitaria de la Ciudad de México, la cual necesita ser atendida por las autoridades universitarias y los profesionales de la salud. La sintomatología depresiva, impulsividad y autoeficacia son factores que se deben considerar para desarrollar estrategias preventivas.

Relación entre supervisión parental y conducta antisocial en menores infractores del Estado de Morelos / Relationship between parent supervision and anti-social behavior in juvenile offenders from the state of Morelos

Resumen: INTRODUCCIÓN: La supervisión parental comprende: cuidado de los hijos, conocimiento de su paradero y actividades y adaptación. Para que ésta se dé es necesario que exista comunicación y apoyo entre padres e hijos, de manera que el ambiente familiar sea agradable. Por otro lado, se ha encontrado que la inconsistencia o ausencia de ésta es un factor de riesgo de la conducta antisocial y, en casos más graves, de delincuencia en los hijos. OBJETIVO: Conocer cuál es la relación que existe entre el ambiente familiar, la supervisión parental y la gravedad de la conducta antisocial en menores infractores. MÉTODO: La población estuvo conformada por menores infractores de un Centro Tutelar del Estado de Morelos. El instrumento se aplicó a 86 hombres. RESULTADOS: La comunicación del hijo fue un predictor de: 1. el manejo de reglas y conocimiento de pares, y 2. el conocimiento de las actividades del hijo. Esto último es lo que predice de manera significativa la gravedad de la conducta antisocial. DISCUSIÓN Y CONCLUSIÓN: De acuerdo con los hallazgos, es importante que exista un ambiente familiar basado en la comunicación y el apoyo, que fomente una comunicación más libre de los adolescentes con sus padres, de manera que la supervisión parental se consiga más fácilmente. Esto ayudará para que los jóvenes no se involucren en comportamientos que los puedan llevar a delinquir.

Abstract: INTRODUCTION: Parental supervision is constituted by a series of correlated parental behaviors involving children care, knowing their where abouts, which activities they are performing, and the situation of their adaptive processes. In order for parental supervision to take place, it is necessary that communication and mutual support exist between mother and father, as well as between parents and children so that the family environment becomes pleasant. Supervision is one of the most studied factors related to anti-social behavior, and it has been observed that its absence or inconsistency allows for the occurrence of anti-social behavior, which in the more serious cases leads to delinquency. OBJECTIVE: To know the relationship between family environment, supervision and the seriousness of anti-social behavior in juvenile offenders confined in a state penitentiary from Morelos. METHOD: A survey was used to collect data from a population of 86 juvenile male offenders from a state penitentiary located in Morelos. RESULTS: Parent-children communication and support are interrelated and form the familiar environment. Thus, children's communication predicts proper supervision and monitoring, specifically in the area of knowing children's activities, which, at the same time, predict less serious anti-social behavior. DISCUSSION AND CONCLUSION: It is important that families have an environment based on communication and support. It is also relevant to encourage adolescents to freely communicate with their parents so supervision and monitoring become common elements that help adolescents to stay away from behaviors that could lead them to crime.

Adaptación y propiedades psicométricas del Inventory of Statements About Self-injury en estudiantes mexicanos / Adaptation and psychometric properties of the Inventory of Statements About Self-injury in Mexican students

Resumen La presente investigación evalúa las propiedades psicométricas de la adaptación al español del Inventory of Statements About Self-injury de Klonsky y Glenn (2009). Esta escala evalúa las diferentes motivaciones o funciones que las personas refieren para realizar autolesiones no suicidas. Se aplicó la escala en una muestra (N = 435) de alumnos universitarios de ambos sexos con una historia de autolesiones no suicidas. El análisis factorial confirmatorio detectó 7 factores interpretables (autorregulación, venganza, búsqueda de sensaciones/fortaleza, evitando el suicidio, manifestando angustia, autodeterminación y embotamiento), 5 más que el instrumento original. La confiabilidad de la escala fue aceptable, con un alfa de Cronbach de 0.89 para la escala total y de 0.72 a 0.82 para cada factor. Se presenta la validez convergente a través de correlaciones positivas entre la escala y mediciones de depresión, ansiedad e impulsividad. El instrumento adaptado al español presenta propiedades psicométricas aceptables para la medición de autolesiones no suicidas en población universitaria mexicana.

Abstract This research evaluates the psychometric properties of the Spanish language adaptation of the Inventory of Statements About Self-injury (Klonsky and Glenn, 2009). This scale assesses the motivations or functions that people with non-suicidal self-injuries report for engaging in self-injurious behaviors. The inventory was administered to a sample of 435 male and female university students with a lifetime history of non-suicidal self-injuries. A confirmatory factor analysis detected 7 interpretable factors (self-regulation, revenge, sensation seeking/toughness, avoiding suicide, marking distress, self-determination and numbness), 5 more than the original instrument. The scale had adequate internal consistency with a Cronbach's alpha of 0.89 and Cronbach's alphas of 0.72 to 0.82 for each factor. Positive correlations between the scale and measures of depression, anxiety and impulsivity suggest the convergent validity of the scale. Overall, the scale presents acceptable psychometric properties for the measurement of non-suicidal self-injuries in a Mexican university population.

Differences in body mass index according to fat mass- and obesity-associated (FTO) genotype in Mexican patients with bipolar disorder.

OBJECTIVES: The prevalence of obesity has dramatically increased in many countries and it is particularly high in patients with bipolar disorder (BD). A region in the first intron of the fat mass- and obesity-associated (FTO) gene, encompassing markers rs9939973, rs8050136, and rs9939609, has been consistently associated with obesity and body mass index (BMI) in different populations. We sought to determine whether FTO is associated with BMI and/or obesity in patients with BD. METHODS: The sample included 129 Mexican Mestizo patients with bipolar I or bipolar II disorder. After obtaining informed consent, participants were evaluated with the Structured Clinical Interview for DSM-IV Axis I Disorders and weight, height, and body measurements were recorded. DNA was extracted from a 5-mL blood sample and real-time polymerase chain reaction was performed. The results were analyzed with Haploview v4.2 and SPSS v21. RESULTS: Differences in mean BMI were explained by rs8050136 and rs9939609 genotypes, especially by comparing non-carriers and carriers of two copies of the risk allele (Tukey's p ≤ 0.019), with a mean difference in BMI as high as 7.81 kg/m(2) . Differences in BMI were also explained by the interaction of the genotype (rs8050136 and/or rs9939609), the use of second-generation antipsychotics, and the use of mood stabilizers (p ≤ 0.41). Obesity was also associated with these two markers when patients with and without obesity were compared. CONCLUSIONS: In patients with BD, differences in BMI may be affected by the presence of FTO risk alleles, especially in homozygous individuals for these variants. Besides evaluating the possible metabolic effects of certain antipsychotics or mood stabilizers, it is important to evaluate the role of other factors such as FTO risk alleles.

Propiedades psicométricas de la Escala Hospitalaria de Ansiedad y Depresión (HADS) en una población de pacientes oncológicos mexicanos / Psychometric properties of the Hospital Anxiety and Depression Scale (HADS) in a Mexican population of cancer patients

ANTECEDENTES: La sintomatología ansiosa y depresiva es parte de los principales problemas de salud mental en pacientes oncológicos, lo cual afecta la calidad de vida y la adhesión al tratamiento, además de que se asocia con mayor número de síntomas y estancia hospitalaria. Mediante instrumentos de tamizaje válidos y confiables, como la Escala hospitalaria de ansiedad y depresión (HADS), ha sido posible detectar posibles casos en pacientes hospitalarios. Sin embargo, hasta ahora no se habían caracterizado las propiedades psicométricas en pacientes oncológicos en población mexicana.OBJETIVO: Determinar las propiedades psicométricas de la HADS en una muestra de pacientes oncológicos.MÉTODO: Participaron 400 pacientes del Instituto Nacional de Cancerología, de los cuales 226 eran mujeres (56.5%) y 174 eran hombres (43.6%); la edad promedio fue de 47.4 ± 14.1 años. Los participantes contestaron, además de la HADS, los siguientes inventarios: depresión de Beck, ansiedad de Beck, termómetro de distrés.RESULTADOS: Un análisis factorial ajustado a dos factores presentó un instrumento con 12 reactivos, similar a la versión original. La consistencia interna de la escala global mostró un índice satisfactorio (a=0.86). Los alfas de Cronbach de cada subescala tuvieron un valor de .79 y .80 que explicaron el 48.04% de la varianza. La validez, por medio de correlación con las medidas concurrentes, mostró resultados significativos (r de Pearson de .51 a .71, p<0.05).DISCUSIÓN Y CONCLUSIÓN: La HADS en pacientes con cáncer en población mexicana presentó adecuadas características psicométricas. La relevancia de los resultados obtenidos radica en que se trata de una población que puede llegar a requerir atención oportuna en salud mental en etapas tempranas de su tratamiento. La detección de sintomatología ansiosa y depresiva por medio de la HADS deriva en beneficios para la población oncológica y en estrategias funcionales de atención adecuada y costo-efectivas.

BACKGROUND: Symptoms of anxiety and depression are among the major mental health problems in cancer patients. These symptoms affect the quality of life and treatment adherence, and are associated with other symptoms and longer hospital stays. Valid and reliable screening instruments such as the Hospital Anxiety and Depression Scale (HADS), have made possible the detection of possible cases of depression and anxiety in medically ill patients. However, the psychometric properties of this instrument have not been documented in different types of cancer diagnoses in the Mexican population.OBJECTIVE: To determine the psychometric properties of the HADS in a sample of patients with cancer from the Mexican population.METHOD: Four hundred patients from the National Cancer Institute participated, of which 226 were women (56.5%) and 174 men (43.6%), with a mean age of 47.4 ±14.1 years. Participants completed concurrently the HADS as well as the following inventories: 1. Beck Depression, 2. Beck Anxiety and 3. Distress Thermometer.RESULTS: A factor analysis adjusted to two factors explained 48.04% of the variance, with 12 items loading on these two factors in a way similar to the original version. The internal consistency of the overall scale was satisfactory (α=0.86). Cronbach's alphas for each subscale were .79 and .80. The concurrent validity assessed by way of correlations with concurrent measures showed significant associations (Pearson r=51-71, p<0.05).DISCUSSION AND CONCLUSION: The HADS has adequate construct validity, internal consistency and concurrent validity for its use in cancer patients from the Mexican population. The relevance of these results is a cost effective tool to provide timely mental health care early in oncological treatment for those in need. Detecting anxiety and depression symptoms through the HADS may benefit cancer patients by ensuring appropriate care that may increase their quality of life and treatment adherence, and reduce their hospital stays.

Intimate partner violence and depressive symptoms in pregnant Mexican women: national survey results.

OBJECTIVES: To analyze the link between intimate partner violence (IPV) reported in the past year and depressive symptoms in pregnant Mexican women. MATERIAL AND METHODS: The data were obtained from the National Addictions Survey (ENA) 2008. For the purposes of this paper, we analyzed a sample of women over 18 who reported being pregnant at the time of the interview (n = 250). When this number is weighted at the population level, it represents 881,575 women across the country. The χ2 test was used to analyze demographic characteristics, prevalence of depressive symptoms and intimate partner violence. A multiple logistic regression was performed to estimate predictors of depressive symptoms during pregnancy. RESULTS: The prevalence of any type of intimate partner violence (IPV) was 5.4% and of depressive symptoms was 16.2% (CES-D ≥ 16). A total of 53.4% of pregnant women who reported IPV during the past year had depressive symptoms whereas this occurred in 14.1% of those who had not been victimized. The variables that predicted depressive symptoms during pregnancy were having been a victim of IPV (OR = 6.23) and having nine years or less of schooling (OR = 5.26). Working outside the home and family income level did not increase the risk of depressive symptoms in this population. CONCLUSIONS: This population study, representative at the national level, provides an initial overview of the link between intimate partner violence and depressive symptoms in pregnant women in México. The results highlight the need to expand research on the topics covered, as well as to detect both phenomena in a timely manner during pregnancy in order to propose the necessary care.

[Social environment and risky eating behaviors: an exploratory study in adolescent females in Mexico]. / Medio ambiente social y conductas alimentarias de riesgo: una exploración en mujeres adolescentes en México.

The objectives of the current study were to explore: (1) the association between the social environment at the city and family levels and risky eating behaviors in adolescent females and (2) the interaction between the social and cultural environment and body mass index (BMI). The data were obtained from a representative survey of female high school students in Mexico State, Mexico (15-19 years). A questionnaire was applied on risky eating behaviors and socio-demographic data. The municipal social and cultural environment was evaluated using the municipal marginalization index. Data analysis used multivariate regression. Prevalence of risky eating behaviors was 4.23%. BMI and family socioeconomic status were directly associated with risky eating behaviors. The municipal marginalization index was not associated with risky eating behaviors. Possible explanations for the latter are that the relevant components of the social and cultural environment were not measured, or that the municipal level does not exert a contextual effect on risky eating behaviors. The effect of BMI on risky eating behaviors was greater in more marginalized municipalities.

Medio ambiente social y conductas alimentarias de riesgo: una exploración en mujeres adolescentes en México / Social environment and risky eating behaviors: an exploratory study in adolescent females in Mexico / Ambiente social e hábitos alimentares de risco: um estudo com mulheres adolescentes no México

Los objetivos de este trabajo fueron explorar: (1) la asociación entre medio ambiente social a niveles municipal y familiar, y conductas alimentarias de riesgo, en mujeres adolescentes; y (2) la interacción entre medio ambiente social y cultural e índice de masa corporal (IMC). La información se obtuvo de una encuesta representativa de las estudiantes de preparatoria en el Estado de México, México (15-19 años). Se aplicó un cuestionario para conductas alimentarias de riesgo y datos sociodemográficos. Se evaluó el medio ambiente social y cultural municipal mediante el índice de marginación del municipio. El análisis se hizo mediante regresión multinivel. La prevalencia de conductas alimentarias de riesgo fue 4,23%. El IMC y el nivel socioeconómico familiar se asociaron directamente con conductas alimentarias de riesgo. El índice de marginación municipal no se asoció con conductas alimentarias de riesgo. Esto puede deberse a que no se midieron los componentes relevantes del medio ambiente social y cultural, o a que el nivel municipal no ejerza un efecto contextual sobre conductas alimentarias de riesgo. El efecto del IMC sobre conductas alimentarias de riesgo fue mayor en municipios más marginados.

Os objetivos deste trabalho foram: (1) explorar a associação entre ambiente social, no nível municipal e familiar, e hábitos alimentares de risco em mulheres adolescentes; e (2) explorar a interação entre ambiente social e cultural e o índice de massa corporal (IMC). Os dados foram conseguidos através de uma pesquisa representativa entre estudantes do segundo grau no Estado de México, México (15-19 anos). Foi aplicado um questionário sobre hábitos alimentares de risco e dados sociodemográficos. O ambiente social e cultural municipal foi avaliado pelo índice de marginalização do município. A análise utilizou o modelo de regressão multinível. A prevalência de hábitos alimentares de risco foi de 4,23%. O IMC e o nível socioeconômico familiar foram diretamente associados a hábitos alimentares de risco. O índice de marginalização municipal não foi associado a hábitos alimentares de risco. Isso pode ser devido ao fato que não foram medidos os componentes relevantes do ambiente social e cultural, ou ao fato que o nível municipal não exerce um efeito contextual sobre hábitos alimentares de risco. O efeito do IMC sobre hábitos alimentares de risco foi maior nos municípios mais marginalizados.

Disordered eating behavior and body weight and shape relatives' criticism in overweight and obese 15- to 19-year-old females.

This study evaluated the link between relatives' criticism of overweight or obese teenage girls' figure and body weight and their relationship with their mothers, fathers and siblings, affection, self-esteem, the internalization of the aesthetic body thin ideal, depressive symptoms and disordered eating behaviors (DEB). The sample comprised 2174 senior high school students aged 15 to 19. Teenagers criticized by their relatives showed higher DEB, without interaction between Body Mass Index (BMI) and DEB. The structural equations model showed DEB was primarily explained by the internalization of the body aesthetic thin ideal, family's criticism, BMI and depressive symptoms.

Population study of depressive symptoms and risk factors in pregnant and parenting Mexican adolescents.

OBJECTIVE: To study the prevalence of, severity of, and risk factors for depressive symptoms in a probabilistic sample of Mexican adolescent mothers. METHODS: A sample of adolescents aged 13-19 years, drawn from a national survey, was interviewed in relation to severity of depressive symptoms [Center for Epidemiological Studies Depression Scale (CES-D) 16-23 and CES-D > 24] and pregnancy or parenting status. RESULTS: Depressive symptoms (CES-D 16-23) ranged from 2.3% in the first postpartum semester to 32.5% in the second trimester of pregnancy; high depressive symptoms (CES-D > 24) ranged from 3.0% in the second postpartum semester to 24.7% in mothers of an infant more than 1 year old. Significant differences between groups were in mothers in the second gestation trimester, who had significantly more symptoms than those who had never been pregnant and those in the first postpartum semester. In those with high symptomatology, no significant differences were observed between groups. A multinomial logistic regression model used to estimate the likelihood of depression found increased risk of depressive symptoms (CES-D 16-23) in those without a partner in the first, second, or third trimester of pregnancy; in the second postpartum semester; and with a child over the age of 1 year. Increased risk of high symptomatology (CES-D > 24) was found in those not in school or with a child over the age of 1 year. CONCLUSIONS: Depressive symptoms entail an enormous burden of disease for the mother and mental health risks to the infant; mothers should therefore be targeted in prevention and intervention actions.

Depresión y consumo de alcohol y tabaco en estudiantes de bachillerato y licenciatura / Depression and alcohol consumption and tobacco in high school and undergraduate

Depression is an emotional upset that disrupts the psycho-affective sphere and is associated with different risk behaviors, as alcohol and tobacco use, among young people. The aim of this study is to analyze the differences on depression in four groups of high school and college students (1. alcohol users, 2. tobacco users, 3. alcohol and tobacco non-users, and 4. alcohol and tobacco users). A census was conducted with 116 214 students with a mean age of 15 and 19 years. Heavy alcohol and tobacco use was more frequent in men. A factorial ANOVA analysis was used to compare depressive symptoms between heavy drinkers (4 or more drinks per occasion) and heavy smokers (4 or more cigarettes per day) by sex and school level. More depressive symptoms were found in college students (M = 9.7) than in the high school ones (M = 9.5, p<0.05). The group of alcohol and tobacco users showed higher levels of depressive symptoms (M=11.3) than the alcohol only (M=10.5) and tobacco only users (M=10.7). Women showed more depressive symptoms (M=10.3) than men. Results point out the need for early detection and intervention, and for more monitoring strategies to develop actions for reducing alcohol and tobacco use in this population and, eventually, depressive outcomes.

La depresión es un malestar emocional que trastoca la esfera psicoafectiva y se asocia con distintas conductas de riesgo como el consumo de alcohol y de tabaco, particularmente en la población joven. El objetivo de este estudio fue analizar las diferencias que existen respecto a la depresión en cuatro grupos de adolescentes (1. consumidores de alcohol, 2. consumidores de tabaco, 3. no consumidores de alcohol ni de tabaco y 4. consumidores de alcohol y tabaco) estudiantes de Bachillerato o Licenciatura. Se realizó un censo con 116 214 estudiantes, con un promedio de edad, en nivel medio superior, de 15 años y de 19 años en nivel superior. El consumo elevado fue más frecuente en los hombres de ambos niveles educativos. Se hizo un análisis de varianza (ANOVA) factorial para determinar las diferencias en la sintomatologia depresiva entre aquéllos que presentaban consumo elevado de alcohol (cuatro o más copas por ocasión) y de tabaco (cuatro o más cigarrillos al dia) por nivel educativo y sexo. Se encontró sintomatologia depresiva más elevada en los estudiantes de nivel superior (M=9.7), en contraste con los jóvenes de medio superior (M=9.5) (p<0.05). Al comparar la sintomatologia depresiva entre los grupos de consumo, los resultados indicaron mayores puntajes en el grupo de consumidores de alcohol y tabaco (M=11.3), seguidos de usuarios excesivos de tabaco solamente (M=10.7) y de alcohol solamente (M=10.5). Las mujeres de ambos niveles educativos presentaron una mayor sintomatologia depresiva (M=10.3), seguidas de los hombres de nivel superior (M=9) y los hombres de nivel medio superior (M=8.8). Los resultados favorecen el desarrollo de acciones de detección e intervención temprana y el monitoreo de esta población.

Confiabilidad y validez de la escala de depresión CES-D en un censo de estudiantes de nivel medio superior y superior, en la Ciudad de México / Reliability and validity of the depression scale CES-D in high school and college students from Mexico city: Results from a census

Introduction Depression and its symptoms are becoming one of the most important health problems worldwide. The impact of depression on the productive life of people, and the burden it represents because of its co-morbidity, is growing. Some authors estimate that depression is the second cause for the global loss of years of healthy life and the first one in developed countries. An increasing proportion of teenage population has mental health issues. Depression and its symptoms are among the most common, but they are not an epidemic problem yet, although spread enough as to maintain interest in its current impact and in its negative consequences over individual health. Depression has a prominent place among mood disorders in Mexico (4.5%), and women are who mostly suffer it (5.8%), which has remained consistent over time. Different difficult situations occur during adolescence along with depression, depressive mood, and depressive symptoms. This situation may be related to changes and processes that occur during this period when individuals cope with situations they cannot handle, which in turn become stressful. Therefore, it is necessary to study and to work with adolescents in order to be able to differentiate affective, cognitive, somatic, and behavioral expressions, which are proper to this stage, from those possibly caused by an illness that could have negative consequences. Adolescent depression influences mood and the way individuals live unpleasant or annoying experiences, thus it affects almost every aspect of life and becomes a risk factor for psychiatric and behavioral problems. However, there are some areas that need more research, for example: the specific characteristics and expressions of the problem including gender comparisons and using designs with special groups. Data show that depression is growing in adolescents; therefore it is a priority to work on detection and prevention to reduce its impact on mental health and to develop cost-effective intervention strategies. One way to do this is using valid-reliable screening tools because they are cheap, and methodologically-logistically useful. The Center for Epidemiological Studies Depression Scale (CES-D) has been used in different studies with Mexican adolescents, and has proven to have good psychometric characteristics. The CES-D has never been used with an entire population in a great scale study. The objective of this paper is to measure the validity and reliability of the scale (construct, concurrent, and external validity, as well as internal consistency) in a population of high school and college freshman students from Mexico City. Method Design. The study was a census made with high school and college freshman students during 2009. Data were collected in 22 schools. Population. A sample of 58568 students participated in the census. The mean age was 1 7 years old (±2.7). Most of the students lived in homes with one to four other persons at the moment of the study (55.4%); 86% said that only their father worked at that moment, and 59.4 said that only the mother; 79.7% of the students lived with both parents, and 1 7.9% only with their mother; 57403 students (98.0% of the population) completed the CES-D in the age range of 14-24 years: 27264 (47.5%) men, and 30139 (52.5%) women. Instrument. The Automated Medical Examination (Examen Médico Automatizado-EMA) is a diagnostic questionnaire designed by the General Directorate of Medical Services (Dirección General de Servicios Médicos) of the Universidad Nacional Autónoma de México (UNAM). It is a questionnaire with four self-report forms that collect information about the physical and mental health, the family, and the general context of every student. This information is used to create a diagnosis of vulnerability and a predictive profile for developing prevention programs, as well as research protocols that help in promoting a culture for health care. The CES-D was included for the measurement in 2009. Results Overall internal consistency was adequate (α=.83). Internal consistency was tested by sex; the coefficient was higher for women (α=.84). Factor analysis generated a four-factor solution (explained variance 54.1%); each factor had good internal consistency and theoretical agreement. The scale showed a significant discriminative power for opposite scores (z=-l44.121, p<.001), and a positive significant correlation with the Okasha Suicidality Scale (rΦ=.325, p = .000). A cut-off point of 16 or higher was established to identify students with high depressive symptomatology. 14.7% of the participants in this study had high depressive symptomatology (11.1% men, 1 7.9% women). Conclusions The CES-D is a valid and reliable epidemiological instrument for different populations. Since depression is a complex and dynamic phenomenon, it is important to evaluate the psychometric properties of any instrument used to measure it. The results of this study showed that the CES-D maintains its internal consistency as well as good concurrent-external validity. Coefficients are higher for women and they increase with age; thus, it would be necessary to refine some aspects to measure younger subjects in a more consistent manner. The data proved that CES-D is a useful instrument for distinguishing different levels of depressive symptomatology; this is relevant because the scale is often used in collective contexts, allowing systematic monitoring of depression with good cost-effective results. Monitoring is also important to keep acceptable levels of emotional wellbeing in student population. Development and refinement of instruments such as the CES-D would potentially lead to opportune and reliable detection of adolescents who may be at risk for suffering mental health problems. This would facilitate implementing more stable and continuous prevention and attention programs to reduce the negative impact of depression in the short term.

Introducción La depresión y sus manifestaciones sintomatológicas son parte de los principales problemas de salud entre la población mundial y su impacto en la vida productiva ha aumentado con respecto a otras enfermedades. En México, esta tendencia y sus consecuencias negativas en el desarrollo hacia la adultez justifican la necesidad de atenderla y prevenirla. A través de instrumentos de tamizaje válidos y confiables como la Escala de Depresión del Centro de Estudios Epidemiológicos [Center for Epidemiological Studies of Depression Scale: CES-D) diseñada en 1977 por Radloff, ha sido posible detectar posibles casos clínicos de depresión en diversos estudios con adolescentes escolares. Sin embargo, hasta ahora no se había documentado su comportamiento en una población de estudiantes a gran escala. Método El levantamiento de la información se realizó en agosto de 2009, previo al inicio del ciclo escolar. Se obtuvo información de 57403 alumnos, de los cuales 47.5% fueron hombres y 52.5% mujeres, con una edad promedio de 17 años (±2.7). Instrumento. La CES-D se incorporó en los formatos del Examen Médico Automatizado (EMA) quese utilizaron para realizar el levantamiento censal entre los alumnos de nuevo ingreso a bachillerato o licenciatura. Resultados Consistencia inferna y validez de constructo. La consistencia interna de la escala global mostró un índice satisfactorio (α=0.83). Los índices de contabilidad fueron adecuados para todos los grupos de edad. El análisis factorial con extracción de componentes principales y rotación oblicua arrojó una estructura de cuatro factores con valores Eigen mayores a uno, que explican 54.1% de la varianza; los coeficientes de consistencia interna y concordancia teórica resultaron satisfactorios: Afecto deprimido, Afecto positivo, Somatización e Interpersonal (como un indicador integrado por sólo dos reactivos). Validez concurrente por medio de grupos contrastados. En la prueba de grupos contrastados se compararon los puntajes globales de la CES-D que se situaron por debajo del percent i I 25 versus aquéllos por arriba del percentil 75. Se utilizó una comparación de promedios de Mann-Whitney, que mostró diferencias estadísticamente significativas entre los cuartiles contrastados (z = -144.121, p<.001). Validez externa. Se analizó mediante su asociación con la Escala de Expectativas de Vivir-Morir de Okasha (que también se aplica en el EMA), obteniendo una correlación positiva y significativa entre quienes tuvieron sintomatología depresiva elevada y quienes manifestaron deseos de morir (rΦ, = 0.325, p = .000). Detección de sintomatología depresiva elevada. La definición operacional de la sintomatología depresiva elevada se definió con el punto de corte (PC) de la CES-D con base en la media más una desviación estándar (PC> 1 6) con lo que se detectó una frecuencia de sintomatología depresiva elevada de 14.7% (n = 8,197): 11.1% en varones y 1 7.9% en mujeres. Conclusiones Los resultados muestran que en poblaciones tan grandes como la del presente estudio, la CES-D es una herramienta útil y adecuada, breve y fácil de aplicar y analizar para establecer un monitoreo que dé respuesta a una de las necesidades más apremiantes en la población escolar: la detección de la sintomatología depresiva elevada como un aspecto importante del malestar emocional. Sirve, además, para determinar la magnitud de la problemática y arribar a su prevención y, de ser el caso, instrumentar acciones para su tratamiento. La relevancia de los resultados obtenidos radica en que se trata de población escolar que puede llegar a requerir atención y prevención oportunas en salud mental en etapas tempranas de la enfermedad, incluso antes de la confirmación diagnóstica en los servicios especializados. Esta detección deriva en beneficios para la población escolar y en estrategias funcionales de atención adecuada y costo-efectivas.

[Association of childhood sexual abuse and disordered eating in a sample of Mexican adolescents]. / Asociación entre abuse sexual infantil y conducta alimentaria de riesgo en una muestra de adolescentes mexicanas.

OBJECTIVE: To analyze the association between childhood sexual abuse (CSA) and disordered eating (DE). MATERIAL AND METHODS: A probabilistic sample of 2,358 female high school students of public schools in the Estado de Mexico was used. RESULTS: DE was more prevalent among CSA sufferers (p < or = 0.05). Preoccupation with gaining weight, binging and restrictive behaviors were associated to CSA (p < or = 0.05). The probability of DE was 7 times higher when the CSA experience had not been revealed and 36 times when CSA happened before 14 years of age. CONCLUSIONS: The association between CSA and DE is clear in the sample studied, as well as with some of its specific characteristics, which highlights the need to deepen in this research field and to incorporate the evaluation of CSA and its consequences in adolescents' mental health.
