Socioeconomic Inequalities in Alcohol and Tobacco Consumption: A National Ecological Study in Mexican Adolescents.

Alcohol and cigarettes are the psychoactive substances that adolescents use most frequently. When both addictions are combined, they carry the worst burden of disease globally. The objective of this study was to identify whether socioeconomic factors correlate with alcohol and tobacco consumption in Mexican adolescents aged 10 years or more and to establish the relationship in the consumption between the two substances. This ecological study utilized data describing alcohol and tobacco consumption among adolescents aged 10-16 years (n = 48,837 ≈ N = 11,621,100). Having ever consumed any alcohol-containing beverage constituted alcohol consumption. Smoking a cigarette within 30 days constituted cigarette consumption. For both variables, the state-level percentages reported in the survey were used. Diverse socioeconomic variables were collected from official sources. Data on the prevalence of tobacco use and alcohol consumption were entered into an Excel database estimated for each of the states of the Mexican Republic, as well as the socioeconomic variables. We performed the analysis using Stata 14. Consumption prevalence was 15.0% for alcohol and 4.2% for tobacco. Alcohol consumption was not correlated with any studied socioeconomic variable (p > 0.05). The prevalence of tobacco consumption among elementary school students correlated (p < 0.05) with the portion of the population living in private dwellings without sewage, drainage, or sanitation (r = 0.3853). The prevalence of tobacco consumption among middle-school adolescents correlated with the portion of the employed population that earned up to two minimum wages (r = 0.3960), the percentage in poverty by income 2008 (r = 0.4754) and 2010 (r = 0.4531), and the percentage in extreme poverty by income 2008 (r = 0.4612) and 2010 (r = 0.4291). Positive correlations were found between tobacco consumption and alcohol consumption among both elementary (r = 0.5762, p=0.0006) and middle-school children (r = 0.7016, p=0.0000). These results suggest that certain socioeconomic factors correlate with tobacco consumption but not alcohol consumption. A correlation between alcohol consumption and tobacco consumption was observed. The results can be used for developing interventions in adolescents.

Perceptions of food environments in the school and at home during Covid-19: An online cross-sectional study of parents, teachers and experts from Latin America.

BACKGROUND: The high prevalence of overweight and obesity in children from Latin America (LA) have been related to obesogenic food environments. Besides, the negative effects of the Covid-19 pandemic should also be considered. The objective of this research was to describe and compare the perceptions of parents, teachers, and experts in LA of food environments at home and school that favor healthy habits in schoolchildren in pre Covid-19 stage and during the pandemic. METHODS: This study used a survey self-reporting regarding conditions at home and the school favoring healthy habits, for three profiles: parents, primary school teachers, and experts. A fisher exact test was used to establish the difference between the response categories between countries and profiles. Logistic regression models were used to determine the probability of response in the levels of importance adjusted for sex and nationality. RESULTS: Information from 954 questionnaires was reported: 48.4% experts, 32.0% teachers, and 19.6% parents. There were differences in the perception of food environments at school between profiles (p<0.001). In multivariate logistic regression models, experts and teachers were 20% more likely to give greater importance to elements of the food environment at school compared to parents (p<0.001). CONCLUSIONS: Our findings showed that parents were less likely to perceive important elements of the school food environment compared to experts and teachers. Interventions are required to improve healthy eating environments that consider children's interpersonal mediators.

Effect of Cognitive Behavioral Intervention Combined with the Resilience Model to Decrease Depression and Anxiety Symptoms and Increase the Quality of Life in ESRD Patients Treated with Hemodialysis.

The aim of this study was to compare the effect of cognitive behavioral intervention (CBI) combined with the resilience model (CBI + R) vs CBI alone on depression symptoms, anxiety symptoms, and quality of life of end-stage renal disease (ESRD) patients undergoing hemodialysis replacement therapy. METHOD: Fifty-three subjects were randomly assigned to one of two treatment groups. The control group (n = 25) was provided with treatment strategies based on a cognitive behavioral approach, while the experimental group (n = 28) were given the same techniques plus resilience model strategies. Five psychological instruments were applied: Beck Depression Inventory, Beck Anxiety Inventory, Mexican Resilience Scale, cognitive distortions scale, and the Kidney Disease related Quality of Life questionnaire. Participants were assessed at baseline (before treatment), eight weeks later (end of treatment), and four weeks after the end of treatment (follow up). The results were analyzed by ANOVA for repeated measures with a Bonferroni-adjusted test method, with p < 0.05 considered significant. RESULTS: The experimental group had significant differences in total and somatic depression as well as differences in the dimensions of cognitive distortions and a significant increase in the dimensions of resilience. The control group had significant differences in all variables but showed lower scores in the evaluated times. CONCLUSIONS: The resilience model strengthens and enhances the effectiveness of the cognitive behavioral approach to reduce symptoms of depression and anxiety in patients with ESRD.

Self-Injurious Behavior and Its Characteristics in a Sample of Mexican Adolescent Students.

Adolescence is a difficult stage, a period of risk for developing disorders, including depression and self-injurious behavior. A non-random sample was drawn (n = 563) from first-year high school students (32.8%) 185 males and 378 females (67.14%) from public schools in Mexico. The age range was 15 and 19 years, with a mean age of 15.63 (SD = 0.78). According to the results, the sample was divided into n1 = 414 (73.3%) adolescents without self-injury (S.I.) and n2 = 149 (26.4%) S.I. adolescents. In addition, results were obtained on methods, motives, time, and frequency of S.I., and a model was generated in which depression and first sexual experience obtained the highest Odd Ratio and d values in their relationship with S.I. Finally, we contrasted the results with earlier reports and concluded that depression is an important variable in S.I. behavior. Early S.I. detection will prevent the aggravation of S.I. and suicide attempts.

Validación de la versión breve del “Cociente de empatía” con adolescentes de México / Validation of the short version of the “quotient of empathy” with adolescents from mexico

La empatía es una habilidad que permite la identificación e interpretación de experiencias subjetivas de otros. El objetivo de este estudio fue validar el “Cociente de empatía” (CE) en adolescentes mexicanos a partir de una muestra de 573 estudiantes (350 mujeres y 223 hombres) con una edad media de 14,8 años (DT= 1,96). Se realizó un análisis factorial exploratorio, identificando dos factores, uno con 16 ítems asociados a la dimensión afectiva y otro de 13 ítems con la dimensión cognitiva (índices de bondad de ajuste: GFI= 0,984, RMSEA= 0,034 y RMSR= 0,072). Para evaluar el modelo bifactorial obtenido, se realizó un análisis factorial confirmatorio, presentando adecuados índices de ajuste (RMSEA= 0,020, RMSR= 0,045, CFI= 0,998, GFI= 0,988). En la consistencia interna se encontró un coeficiente de correlación ω de McDonald de 0,941 para la dimensión afectiva y 0,772 para la dimensión cognitiva (p< 0,001). La validación de este instrumento de empatía apoyará su uso como herramienta de evaluación en investigación clínica en adolescentes mexicanos. (AU)

Empathy is a skill that enables the identification with and interpretation of others' subjective experiences. The purpose of this study was to validate the Empathy Quotient (EQ) in adolescents in Mexico. A sample of 573 Mexican adolescent students (350 female and 223 male) with an age range of 12-19 years was employed (Mage= 14.8 years, SD= 1.96). An exploratory factor analysis (EFA) was carried out which identified two factors, one with 16 items associated with the affective dimension and one with 13 items related to the cognitive dimension (model fit indices: GFI= .984, RMSEA= .034, and RMSR= .072). To evaluate the resultant bifactor model, a confirmatory factor analysis (CFA) was performed, showing good fit indexes (RMSEA= .020, RMSR= .045, CFI= .998, GFI= .988). Regarding internal consistency, we found a McDonald's ω correlation coefficient of= .941 for the affective dimension and ω= .772 for the cognitive dimension, with p< .001. The validation of this empathy instrument will support its use as a clinical research assessment tool in Mexican adolescents. (AU)

Abstract: Objective: To evaluate the effectiveness of a multidisciplinary online intervention (psychological, medical, and nutritional) in women with binge eating disorder (BED). Method: 5 women diagnosed with BED with a mean age of 43.2 years and a mean initial body weight of 90 kg participated. The treatment was carried out during 24 sessions, each of two hours per week; the first hour was group therapy and the second individual. There were four moments of evaluation: pre, post and two follow-ups. Results: The comparisons were made through the non-parametric Friedman test, finding a statistically significant decrease in binge eating symptoms before χ1= 30.30 at the second follow-up χ2 =10.80 (x2=12.84; p=.005), symptoms of anxiety χ1= 28.80, χ2=12.40 (x2=10.83.96; p=.013) and depression χ1= 19.80, χ2=4.0 (x2= 10.18, p=.017). Improvement was observed in comprehension χ1= 21.00, χ2=30.20 (x2=9.63; p=.025) and emotional regulation χ1= 28.40 χ2=33.00, (x2=7.77; p=.050). The patients reduced their body weight, improved their eating habits by introducing fruit and vegetables daily and included physical activity in their daily routine, performing 20 to 30 minutes a day. From the objective clinical change, a positive change was observed in the variables addressed in treatment in all the participants. Conclusions: The online multidisciplinary intervention was effective in the treatment of BED in women.

Risk patterns in food addiction: a Mexican population approach.

BACKGROUND: Food addiction (FA) is a construct that has gained interest in recent years but its relevance in Mexican population is still unexplored. AIMS: The present study has the aims of explore FA in a community of Mexican population, as well as identifying the risk patterns associated with it, in relation to the different etiological factors that have been described such as impulsivity, emotional regulation and eating styles. Furthermore, to identify a predictive model of FA severity. METHODS: The sample consisted of 160 female and male university students of Pachuca city in México, who volunteered to participate in the study. Assessment included multidimensional measures for FA, eating disorder severity, eating disorder styles, emotional regulation and impulsivity. RESULTS: A screening of FA-probable was registered for 13.8% of the sample, while 8.1% met criteria for FA-present. The FA-present group differed from FA-absent in the impulsivity levels and in emotional eating style. Patients with FA-present differed from FA-probable in the impulsivity levels. Differences between FA-probable versus FA-absent were found in the restrained eating style. Path analysis evidenced that FA severity was directly associated with older age, worse eating style profile and higher impulsivity levels, and indirectly related with the ED symptom levels. CONCLUSIONS: Our findings suggest that it is possible to establish a specific predictive model of the development of FA and its severity in Mexican population to implement adequate prevention and treatment strategies. EVIDENCE LEVEL: Level III: evidence obtained from well-designed cohort or case-control analytic studies.

Psychometric Assessment of an Online Self-Test Measuring Risky Eating Behavior, Depression, Social Anxiety, and Self-Injury in Mexican Adolescents.

The objective of this study was to evaluate the validity and reliability of OTESSED, an online test for the self-detection and prevention of risk factors for eating disorders and related problems, such as depression, social anxiety, and self-injury, in samples of male and female adolescents. Participants formed a non-probability sample of N = 577 high school students. The mean ages of boys and girls were the same (Mage = 15.61; SD = 0.73). Among the main results, scales of depression, self-injury, social anxiety, and risky eating behavior (REB) with construct validity (CFA) were obtained. The first two showed the same structure (two factors per sex), with an appropriate reliability omega value (0.92), and a similar percentage of explained variance (≥50). The REB scale presented two factors for boys and three for girls, with an appropriate omega value (0.88) and explained variance percentage (0.56). The instrument validation process was completed, meeting the discriminant validity criterion for each scale of the OTESSED.

Resilience: A Protective Factor from Depression and Anxiety in Mexican Dialysis Patients.

Depression and anxiety are highly prevalent psychological disorders in end-stage renal disease (ESRD) that have a negative clinical impact. The purpose of our study was to identify factors associated with the presence of depression and anxiety, in a sample of ESRD patients treated with hemodialysis. We included 187 patients from two dialysis facilities, age 18-65 years. Beck's depression and anxiety inventories, KDQOL36 questionnaire, the cognitive distortion scale and the Mexican scale of resilience were used. Socio-demographic and clinical information was obtained from medical records. Depression was present in 143 (76.4%) patients. Patient with depression were older (33 (26-52) years vs. 30 (24.43) years, p = 0.025), had a lower education level (36% vs. 9%, p = 0.001), used more medications (67% vs. 36%, p = 0.001), had a comorbidity (75% vs. 41%, p = 0.001), and a higher proportion were waiting for a kidney transplant. Anxiety was present in 112 (59.8%) cases. By multivariate analysis, depression was independently associated with lower education, absence of previous kidney transplant, anxiety, higher cognitive distortion, lower psychological resilience, and lower quality of life scores. In conclusion, lower psychological resilience, lower education level, and higher cognitive distortions are factors associated with depression and anxiety in ESRD patients.

Multi-Validity Process and Factor-Invariance. Perceived Self-Efficacy-Scale for the Prevention of Obesity in Preteens.

Given the lack of scales with a robust psychometric assessment of self-efficacy related to obesity in early adolescence, we aimed to obtain an instrument with high-quality validity and reliability items. Nonrandom samples (N = 2371) classified boys (1174, M = 12.83, SD = 0.84) and girls (1197, M = 12.68, SD = 0.78) from Mexico City and some cities of the Mexican Republic with obesity rates near to the national level mean. A multi-validity process and structural invariance analysis using the Perceived Self-efficacy Scale for Obesity Prevention were performed. A two-factor-physical activity and healthy eating-model with high effect-sized values-girls R2 (0.88, p < 0.01) and boys R2 (0.87, p < 0.01)-were obtained. Each factor explained more than half of the variance with high-reliability coefficients in each group and acceptable adjustment rates. The self-efficacy scale proved to have only girls, an invariant factor structure, or a psychometric equivalence between the groups. The obtained scale showed that a two-factor structure is feasible and appropriate, according to the highest quality of validity and reliability.

Prevalence of 12-month mental and substance use disorders in sexual minority college students in Mexico.

PURPOSE: Mental health disparities have been documented among sexual minority college students, but there is a dearth of evidence from developing countries. The aim is to estimate the prevalence of 12-month mental and substance use disorders across a range of sexual identities among first-year college students in Mexican universities, and test whether there is an association between sexual identity and disorders and whether the association is moderated by gender. METHOD: The University Project for Healthy Students, a web-based survey conducted as part of the World Health Organization's World Mental Health International College Student initiative, recruited 7874 students from nine Mexican universities in 2016 and 2017. Logistic regressions estimated the association of sexual identity with 12-month major depressive episode, generalized anxiety disorder, panic disorder, alcohol abuse/dependence, and drug abuse/dependence, with interaction terms for gender. RESULTS: Compared to heterosexual students reporting no same-sex attraction (SSA), heterosexual students with SSA (AORs range 1.77-3.67) and lesbian/gay and bisexual students (AORs range 2.22-5.32) were at a higher risk for several disorders. Asexual students were at higher risk for drug abuse/dependence (AOR = 3.64). Students unsure of their sexual identity were at a higher risk for major depressive episode, panic disorder, and drug abuse/dependence (AORs range 2.25-3.82). Gender differences varied across sexual identity and disorder. CONCLUSION: These findings are the first empirical report of sexual minority psychiatric disparities among a college student population from a developing nation and underscore the importance of clinical interventions that address mental health needs among sexual minority college students.

Academic Performance during the COVID-19 Pandemic and Its Relationship with Demographic Factors and Alcohol Consumption in College Students.

The COVID-19 pandemic has caused many changes in the education sector worldwide, and school curricula have had to adapt to a non-face-to-face modality. However, international studies have concluded that this modality has affected the academic performance of students. The present study aimed to compare the academic performance of a sample of college students from before the start of quarantine with their current performance, and to test whether various demographic factors influenced these changes in conjunction with alcohol consumption. With a non-experimental, comparative and longitudinal design, we applied an ad hoc questionnaire, in conjunction with the AUDIT questionnaire, in a sample of college students (n = 341), and we also obtained data of academic average and failed subjects. The demographic factors that influenced academic performance were sex (p < 0.01), age (p < 0.01) and alcohol consumption (p = 0.001). Most students showed an improvement in their academic average during the quarantine period. Women without failed subjects and low-risk alcohol consumption obtained a better average in this period. In conclusion sex, age and alcohol consumption level were factors associated with academic performance during the quarantine period due to the COVID-19 pandemic; and women had a higher academic average than men did.

Suicide thought and behaviors, non-suicidal self-injury, and perceived life stress among sexual minority Mexican college students.

BACKGROUND: Sexual minority college students are at a higher risk for suicidal thoughts and self-injurious behaviors compared to heterosexual students. Minority stress theory proposes sexual minority individuals experience higher stress due to stigma. Using a sample of Mexican college students, this study tested perceived life stress as a mediator of suicide and self-injury outcomes across various sexual orientation groups. METHODS: The sample of college students (N=7882) was recruited from nine Mexican universities as part of the WHO World Mental Health International College Student (WMH-ICS) initiative. Participants completed an online survey including demographic questions, measure of perceived life stress, suicide outcomes, and non-suicidal self-injury (NSSI) in the past 12 months. RESULTS: Logistic regression analyses revealed identifying as a sexual minority significantly predicted a higher likelihood of suicide ideation (ORs 2.05-3.00), suicide attempts (ORs 2.48-8.73), and NSSI (ORs 2.92-4.18) compared to heterosexual students reporting no same-gender attraction. Significant indirect effects from mediation path analyses showed perceived life stress mediated the relationship between a sexual minority identity and suicide ideation (range of proportion mediated 10.48-31.48%), attempts (10.48-31.48%), and NSSI (7.69-20.09%) across each group except among asexual students. LIMITATIONS: The cross-sectional nature of the survey design precludes drawing causal inferences. CONCLUSION: Findings from this study contribute to minority stress theory by elucidating the role of perceived life stress as a mediator of suicide ideation and attempts and NSSI among sexual minority college students. Clinical interventions may benefit in focusing on experiences of stress across various life areas when supporting sexual minority college students.

Calidad de vida relacionada con la salud en adultos con normopeso, sobrepeso y obesidad / Health-related quality of life in normal weight, overweight and obese adults

Resumen Actualmente el sobrepeso y la obesidad presentan una alta prevalencia a nivel mundial, y se encuentran relacionados con enfermedades crónico-degenerativas, mortalidad prematura y disminución en la calidad de vida. El propósito de esta investigación fue comparar la calidad de vida relacionada con la salud (CVRS) en función del estado de nutrición (EN) y sexo. Participaron 202 adultos (84 hombres y 118 mujeres), con una edad entre 18 y 81 años (M =39.74 DE = 13.77), quienes fueron distribuidos por su EN en: normopeso, sobrepeso y obesidad. Los participantes completaron el cuestionario 36-Item Short Form Health Survey (SF-36). En la muestra predominó la dimensión Función física (FF), considerándola muy buena. Las dimensiones Rol emocional (RE), Rol físico (RF), Vitalidad (VT) y Salud mental (SM) se ubicaron en el nivel de bueno, y solamente la Salud general (SG) se consideró regular. En el caso de la comparación entre los grupos en función del EN no se encontraron diferencias significativas; sin embargo, en la comparación por sexo, los hombres obtuvieron mayores puntuaciones en: FF, SM, VT y RE. Se concluye que no hay diferencia estadísticamente significativa de la CVRS entre los grupos por EN, no obstante, al realizar la comparación por sexo se encuentran diferencias significativas a favor de los hombres.

Abstract Overweight and obesity currently have a high prevalence worldwide, are related to chronic degenerative diseases, premature mortality and the decline in quality of life. The purpose of the present investigation was to compare the quality of life related to health (HRQoL) between groups by their nutritional status (NS) and by sex. There was a sample of 202 participants (84 men and 118 women) with an age between 18 and 81 years (M =39.74 SD = 13.77), distributed by their NS in: normal weight, overweight and obesity, they were administered the questionnaire 36-Item Short Form Health Survey (SF-36). In the general sample, the Physical Function (PF) dimension was predominant, being considered as very good, the scores obtained in the Emotional Role (ER), Physical Role (PR), Vitality (VT) and Mental Health (MH) dimensions were in a range estimated as good and only the General Health (GH) dimension was considered regular. In the case of the comparison between the groups by state of nutrition, no statistically significant differences were found between them, however, in the comparison made by sex, statistically significant differences were found in the factors of PF, MH, VT and ER in favor of the group of men. In conclusion, there is not statistically significant difference of the HRQoL between the groups by NS, nevertheless, when performing the comparison by sex, significant differences are found in favor of the men.

Caffeine Consumption in Children: Innocuous or Deleterious? A Systematic Review.

Caffeine is the most consumed psychostimulant worldwide. Its use among children is controversial. Although it produces an increase in brain activity, it could hamper growth and development in young consumers. Therefore, the aim of this review was to recognize changes produced by caffeine in children under 12 years of age and to identify the relevant alterations and the conditions of their occurrence. A systematic review of the literature was carried out using PRISMA. Initially, 5468 articles were found from the EBSCO, ScienceDirect, PubMed, and Clarivate Analytics databases. In this review, were retained 24 published articles that met the inclusion criteria. The results obtained showed that caffeine consumption hampers children's growth and development. In contrast, it supports the activation of the central nervous system and brain energy management.

Prevalence of Antibiotics Prescription and Assessment of Prescribed Daily Dose in Outpatients from Mexico City.

Pharmacoepidemiological research about antibiotics is supported by the World Health Organization (WHO), but data regarding antibiotic prevalence based on actual prescriptions and dosing patterns are insufficient. The aims were: (i) To estimate the prevalence and prescribed daily dose (PDD) of antibiotics in outpatients from Mexico City and (ii) to compare the PDD against the defined daily dose (DDD), as established by the WHO. The study included 685 prescriptions of antibiotics selected randomly from five geographical zones of Mexico City. Drug, dose, frequency, and duration of treatment were obtained from each prescription. PDD values of each antibiotic drug were calculated as the average of the daily doses. Sub-use and overuse were determined by the ratio PDD/DDD for each prescription. The most prescribed antibiotics to outpatients from Mexico City included six pharmacological groups: quinolones (28%), penicillins (23%), cephalosporins (17%), macrolides (10%), lincosamides (9%), and sulfonamides (4%). Both overuse and sub-use were high (55% and 63%, respectively). In conclusion, most of the antibiotics with a high prevalence of prescription also had a high rate of either sub-use or overuse, with prescribed doses that significantly differ with their corresponding DDD. The dosing variation has important clinical implications since it denotes low prescription control.

Prácticas alimentarias de mujeres indígenas en función del estado nutricio y sexo de sus hijos/as / Food practices of indigenous women according to the nutritional status and sex of their children

Resumen El objetivo de esta investigación fue describir las prácticas alimentarias (PA) de mujeres indígenas de Hidalgo (México), a partir del sexo y el estado nutricio (EN) de sus hijos/as. Participaron 19 diadas madre-hijo/a (Medad madre = 33.5 años, DE= 7.1; Medad hijo = 6.0 años; DE = 0.4). Las madres fueron entrevistadas y, para estimar el EN de sus hijos/as, estos fueron pesados y medidos. La información fue analizada mediante categorías basadas en los factores del Cuestionario de Actitudes, Creencias y Prácticas de los Padres hacia la Alimentación de sus Hijos. Aunque las madres con hijos/as saludables (estatura normal y normopeso) y aquellas otras de hijos con mala nutrición mostraron PA comunes, también presentaron algunas diferencias. Éstas principalmente relacionadas con la percepción del peso de su hijo/a, la que no fue congruente con el EN real, caracterizándose por la subestimación. En ambos sexos (hijo/hija) se notó una presencia alta de casi todas las categorías de análisis, pero mayormente entre aquellas madres con niñas. Este estudio representa un primer acercamiento al conocimiento de las PA maternas de mujeres indígenas en función del EN y sexo de sus hijos, cuyos resultados fundamentan la necesidad de seguir profundizando en el estudio de este tipo de población.

Abstract The purpose of this research was to describe the eating practices (EP) of indigenous women in Hidalgo (Mexico), based on their children's sex and nutritional status (NS). A total of 19 mother-child dyads participated (Mage mother = 33.5 years, SD = 7.1, Mage children = 6.0 years, SD = 0.4). The mothers were interviewed and, to estimate the NS of their children, they were weighed and measured. The information was analyzed by categories based on the factors of the Questionnaire of Attitudes, Beliefs and Practices of the Parents towards the Feeding of their Children. Alt hough mothers with healthy children (height normal and normal weight) and those of children with poor nutrition showed common EP, they also presented some differences. These were mainly related to the perception of the weight of their children, which was not consistent with the real NS, characterized by underestimation. In both sexes (son/daughter) there was a high presence of almost all categories of analysis, but mostly among mothers with girls. This study represents a first approach to the knowledge of the maternal EP of indigenous women according to the NS and sex of their children, whose results support the need to continue deepening the study of this type of population.

Validación de un instrumento de autoeficacia para la prevención de obesidad en niños escolares / Validation of an instrument of self-efficacy for the prevention of obesity in school children

El objetivo de este estudio fue adaptar y evaluar, desde una perspectiva psicométrica, un instrumento dirigido a medir la autoeficacia relativa al control del peso en niños de enseñanza básica. Mediante laboratorios cognoscitivos, los ítems del instrumento original se adaptaron para su uso en niños de edad escolar, y posteriormente fueron validados por un panel de jueces. Esta versión del instrumento fue aplicada a 1,151 participantes, mujeres y varones, de entre 8 y 13 años de edad (M = 10.2, DE = 0.98), y examinada a través de análisis factorial exploratorio y análisis factorial confirmatorio. El análisis factorial exploratorio arrojó una estructura de cuatro factores, con 25 ítems (α = 0.90), mientras que el AFC derivó un modelo de tres factores, con 20 ítems (α = 0.88), el cual mostró buen ajuste (χ 2 /gl= 2.47; AGFI = 0.95; NFI = 0.93; CFI = 0.95; GFI = 0.96; RMSEA= 0.03, 90% [IC 0.034-0.042]). Se obtuvo un instrumento parsimonioso, con validez y consistencia interna aceptables, el cual permite medir tres componentes básicos de la autoeficacia relativa a la prevención del sobrepeso, que son: actividad física, alimentación y control sobre la alimentación emocional, aspectos no abordados en instrumentos precedentes.

The objective of this study was to adapt and evaluate, from a psychometric perspective, an instrument aimed at measuring self-efficacy and weight control in elementary school children. Through cognitive laboratories, the items of the original instrument are adapted for children of school age, and subsequently validated by a panel of judges. This version of the instrument was applied to 1151 participants, girls and boys of between 8 and 13 years old (M = 10.2, SD = 0.98), and examined through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The EFA derived a four-factor structure, with 25 items (α = 0.90), while the CFA derived a three factor model, with 20 items (α = 0.88), which showed a good fit (χ 2 /gl = 2.47, AGFI = 0.95, NFI = 0.93, CFI = 0.95, GFI = 0.96, RMSEA = 0.03, 90% [IC 0.034-0.042]). A parsimonious instrument with acceptable internal validity and consistency was obtained, which allows to measure three basic components of self-efficacy relative to the prevention of overweight, which are: physical activity, feeding and control over emotional feeding, not addressed in previous instruments.

Imagen corporal e índice de masa corporal en mujeres indígenas del Estado de Hidalgo, México / Body image and body mass index of indigenous women from Hidalgo state, Mexico

El objetivo de este estudio fue examinar la relación entre el índice de masa corporal (IMC) y la imagen corporal de mujeres indígenas de Hidalgo, México. En 167 mujeres adultas (M edad = 34.45, DE = 6.76), la satisfacción/insatisfacción corporal se estimó según el IMC y la técnica parcial del marcado de imagen. El 83% de las mujeres evaluadas presentaron algún grado de insatisfacción corporal, mayormente relacionado con el deseo de adelgazar (51%) que con el de ser más robustas (32%). Las mujeres más satisfechas con su imagen corporal fueron las normopeso (21%) o con bajo peso (20%); por el contrario, las menos satisfechas fueron aquellas con obesidad (57%). Sin embargo no se identificó una asociación significativa entre el IMC y la satisfacción/insatisfacción corporal. Una de las principales aportaciones de este estudio es haber analizado la correspondencia entre dos variables poco estudiadas en mujeres adultas indígenas: el IMC y la imagen corporal, cuyos resultados fundamentan la necesidad de seguir investigando este tipo de población, así como el desarrollo de programas de prevención y de promoción de la salud específicos a grupos indígenas.

The objective of this study was to determine the relationship between the body mass index (BMI) and the body image of indigenous women from Hidalgo, Mexico. Body dissatisfaction/satisfaction was evaluated in 167 adult women (M age = 34.45, SD = 6.76) based on BMI and on the partial markup technique of image. The 83% of women assessed had some degree of body dissatisfaction specially related to the desire of thinness (51%) than with the desire of being robust (32%). Normal weight (21%) and low weight (20%) women were those who were more satisfied with their body image; on the contrary, women with obesity (57%) were the less satisfied. However a significant association among BMI and body satisfaction/dissatisfaction was not identified. One of the main contributions of this study was to analyze the correspondence between two little studied variables in indigenous adult women: BMI and body image. These findings strength the need to keep studying this kind of population as well as the development of preventive and promoting health programs aimed to indigenous groups.

Design and evaluation of a campaign to promote the consumption of vegetables and fruits in Mexican school-age children.

INTRODUCTION: In Mexican school-age children the consumption of vegetables and fruits (V&F) is less than 25% of the amount recommended by the World Health Organization. OBJECTIVES: Evaluate the effectiveness of a promotion campaign about the consumption of V&F in urban school children from Hidalgo, Mexico. METHODS: A non controlled community trial in 226 school-age children from private and public schools was conducted, we designed and distributed printed material for promoting the consumption of V&F among the school population, access to V&F was provided through planning and sales at school stores, and consumption was supervised by the teachers. RESULTS: At the end of the intervention vegetable consumption increased by 50 g and plain water in 100 mL (T-test, p < 0.05); the proportion of school-age children who identified the health benefits of the consumption of V&F increased significantly (68% initial, 87% final) and greater support from parents (61% initial, 92 final%) was achieved. CONCLUSIONS: A promotion campaign and improved access to vegetables, fruits and water in the school environment which is supported by parents and teachers can encourage healthier eating at school.
