Resumen: Objetivo: Evaluar la cobertura de atención del parto eutócico en Unidad Centinela (UC), de primer nivel de atención. Verificar el cumplimento de lo establecido en el modelo e identificar los factores que impiden o favorecen su uso, desde la perspectiva de los prestadores de salud y de las usuarias. Materiales y métodos: Estudio con un componente cuantitativo y uno cualitativo, retrospectivo, con información de bases primarias y secundarias. Variable principal: Atención del parto eutócico, Análisis: Descriptivo, porcentajes para variables categóricas y promedios δ para variables continuas, diferencias estadísticas entre dos variables categóricas, Chi2 de Pearson. Multivariado: Regresión logística de factores asociados a la atención del parto. Se realizaron 12 entrevistas semiestructuradas a usuarias y 8 prestadores de servicios, el análisis se realizó con base en la Teoría Fundamentada a través de Ethnograph v.5. Resultados: Muestra: 218 usuarias, edad promedio fue 24.7 años. La UC proporcionó control prenatal, el 61% más de 5 consultas; sin embargo, la atención de partos eutócicos solamente fue de 17 partos (33.4%). Las barreras más importantes referidas por las usuarias y prestadores de salud fueron: falta de personal, capacitación, insumos, apoyo insuficiente y protección legal institucional en caso de complicaciones. Conclusiones: La UC es una estrategia para regresar la atención de partos al primer nivel de atención, pero es necesario implementar un plan de mejora y fortalecimiento de los proveedores.

Abstract: Objective: Evaluate the coverage of eutocic delivery care in the Sentinel Unit (UC), of the first level of care, verify compliance with what is established in the model and identify the factors that prevent or favor its use, from the perspective of the providers of health and users. Materials and methods: Qualitative and quantitative study, retrospective with information on the primary and secondary bases. Main variable: care of eutocic delivery. Analysis: Descriptive, percentages for categorical variables and δ means for continuous variables, statistical differences between two categorical variables, Pearson Chi2. Multivariate: logistic regression of factors associated with delivery care. Twelve semi-structured interviews were conducted with users and 8 service providers, the analysis was carried out based on Grounded Theory through Ethnograph v.5. Results: Sample: 218 users, average age was 24.7 years. The UC provided prenatal control, 61% more than 5 consultations; however, the care of eutocic deliveries was only 17 deliveries (33.4%). The most important barriers referred to by the users and health providers were: lack of personnel, training, supplies and insufficient support and institutional legal protection in case of complications. Conclusions: UC is a strategy to return delivery care to the first level of care, but it is necessary to implement a plan to improve and strengthen providers.

Association between mortality and cardiovascular diseases in the vulnerable Mexican population: A cross-sectional retrospective study of the COVID-19 pandemic.

Cardiovascular diseases (CVDs) continue to be the leading cause of death worldwide. Over the past couple of years and with the surge of the COVID-19 pandemic, mortality from CVDs has been slightly overshadowed by those due to COVID-19, although it was during the peak of the pandemic. In the present study, patients with CVDs (CVDs; n = 41,883) were analyzed to determine which comorbidities had the largest impact on overall patient mortality due to their association with both diseases (n = 3,637). Obesity, hypertension, and diabetes worsen health in patients diagnosed positive for COVID-19. Hence, they were included in the overview of all patients with CVD. Our findings showed that 1,697 deaths were attributable to diabetes (p < 0.001) and 987 deaths to obesity (p < 0.001). Lastly, 2,499 deaths were attributable to hypertension (p < 0.001). Using logistic regression modeling, we found that diabetes (OR: 1.744, p < 0.001) and hypertension (OR: 2.179, p < 0.001) significantly affected the mortality rate of patients. Hence, having a CVD diagnosis, with hypertension and/or diabetes, seems to increase the likelihood of complications, leading to death in patients diagnosed positive for COVID-19.

Estudio de la calidad de vida en cuidadores familiares de personas con discapacidad intelectual.

OBJETIVO: Explorar las experiencias y percepciones de la calidad de vida (CV) en cuidadores familiares (CF) de personas con discapacidad intelectual (PDI) en Morelos y Sinaloa, México. Material y métodos. Estudio cualitativo. Se realizaron 18 entrevistas semiestructuradas a CF de PDI que asistían a escuelas básicas públicas en Huitzilac, Morelos y Culiacán, Sinaloa, México. Se realizó análisis de contenido con apoyo del programa ATLAS.ti.8.0. RESULTADOS: Los CF experimentaron un deterioro en distintas dimensiones: bienestar emocional, físico y material, desarrollo personal, autodeterminación y relaciones interpersonales, deterioro que afecta negativamente su CV. Los lazos de empatía, acompañamiento y motivación con otros CF son beneficiosos y los libera de actividades por lapsos breves, disminuyendo así la carga del cuidado de una PDI. CONCLUSIONES: Cuidar a una PDI puede afectar negativamente la CV de las y los CF. Se sugiere el desarrollo de intervenciones para atención, apoyo y orientación integral; asimismo, crear y fortalecer grupos de ayuda mutua con otros cuidadores.

Medical outcomes study social support survey (MOS-SSS) in patients with chronic disease: A psychometric assessment.

Purpose: Currently, information on the psychometric properties of the Medical outcomes study-social support survey (MOS-SSS) for patients with chronic disease in primary health care, suggests problems in the dimensionality, specifically predominant unidimensionality in a multidimensional measure. The aim of this study was to determine the internal structure (dimensionality, measurement invariance and reliability) and association with other variables. Methods: A total of 470 patients with chronic disease from a Family Medicine Unit at the Instituto Mexicano del Seguro Social, IMSS, with a mean age of 51.51 years were included. Participants responded to the Questionnaire of Sociodemographic Variables (Q-SV), SF-36 Health-Related Quality of Life Scale-version 1.1, and MOS-SSS. Results: Non-parametric (Mokken scaling analysis) and parametric (confirmatory factor analysis) analyses indicated unidimensionality, and three-factor model was not representative. A new 8-item version (MOS-S) was developed, where measurement invariance, equivalence with the long version, reliability, and relationship with the SF-36 were satisfactory. Conclusion: The MOS-SSS scale is unidimensional, and the shortened version yields valid and reliable scores for measuring social support in patients with chronic disease at the primary health care.

Abstract: Objective: To summarize the scientific evidence of adverse health effects of Covid-19 during pregnancy. Materials and methods We conducted a Cochrane rapid review. Meta-analysis of proportions and odds ratios (OR) were performed. Results: Frequent maternal events included invasive mechanic ventilation and admission to the intensive care unit (ICU); pregnancy complications were fetal distress and premature rupture of membranes; common comorbidities were obesity and asthma. Deliveries by cesarean section (C-section) due to Covid-19 were frequent (51%). The most frequent neonatal outcomes were low birthweight and prematurity; we identified cases of SARS-CoV-2 positive neonates (14%). Pregnant women with Covid-19 were more likely to deliver by C-section (pooled OR=6.7) and prematurely (pooled OR=2.9); neonates were more likely to be admitted to the neonatal ICU (pooled OR=5.9). Conclusion: The available evidence on Covid-19 during pregnancy is limited. Therefore, we cannot disregard adverse health effects on the mother-child pair, particularly those related to C-sections and premature deliveries.

Predictors of Quality of Life among Parents of Children with Chronic Diseases: A Cross-Sectional Study.

Quality of life (QOL) is a key aspect of the health care process for children with chronic diseases and their families. Although clinical evidence regarding the impact of chronic disease on children exists, few studies have evaluated the effects of the interaction between sociodemographic and psychosocial factors on the family caregiver's QOL, indicating a significant gap in the research literature. The present study aimed to identify the predictors of the QOL of parents of children with chronic diseases. Three parental sociodemographic predictors (age, schooling, and family income) and four psychosocial predictors (family functioning, social support, depression, and resilience) were examined. In this cross-sectional study, 416 parents of children with chronic diseases who were hospitalized at a National Institute of Health in Mexico City were interviewed. The participants completed a sociodemographic variables questionnaire (Q-SV) designed for research on family caregivers of children with chronic disease. The predicted variable was assessed through the World Health Organization Quality of Life Questionnaire. The four psychosocial predictors were assessed through the Family Functioning Scale, Social Support Networks Scale, Beck Depression Inventory, and Measurement Scale of Resilience. The regression model explained 42% of the variance in parents' QOL. The predictors with positive weights included age, schooling, monthly family income, family functioning, social support networks, and parental resilience. The predictors with negative weights included depression. These findings suggest that strong social relationships, a positive family environment, family cohesion, personal resilience, low levels of depression, and a family income twice the minimum wage are variables associated with better parental QOL.

Validity and Reliability of the Beck Anxiety Inventory (BAI) for Family Caregivers of Children with Cancer.

Currently, information about the psychometric properties of the Beck Anxiety Inventory (BAI) in family caregivers of children with cancer is not available; thus, there is no empirical evidence of its validity and reliability to support its use in this population in Mexico or in other countries. This study examined the psychometric properties of the BAI in family caregivers of children with cancer and pursued four objectives: to determine the factor structure of the BAI, estimate its internal consistency reliability, describe the distribution of BAI scores and the level of anxiety in the sample and test its concurrent validity in relation to depression and resilience. This cross-sectional study was carried out with convenience sampling. A sociodemographic questionnaire, the BAI, the Beck Depression Inventory and the Measurement Scale of Resilience were administered to an incidental sample of 445 family caregivers of children with cancer hospitalized at the National Institute of Health in Mexico City. Confirmatory factor analysis using the maximum likelihood method was performed to determine the factor structure and exploratory factor analysis using axis factorization with oblique rotation was conducted. The two-, three- and four-factor models originally proposed for the BAI did not hold. The exploratory factor analysis showed a model of two correlated factors (physiological and emotional symptoms). Confirmatory factor analysis revealed a lack of discriminant validity between these two factors and supported a single-factor model. The internal consistency of the scale reduced to 11 items (BAI-11) was good (alpha = 0.89). The distribution of BAI-11 scores was skewed to the left. High levels of symptoms of anxiety were present in 49.4% of caregivers. The scale was positively correlated with depression and negatively correlated with resilience. These findings suggest that a reduced single-factor version of the BAI is valid for Mexican family caregivers of children with cancer.

Síntomas depresivos y niveles séricos de ácidos grasos poliinsaturados omega-3 y omega-6 en universitarios del norte de México / Depressive symptoms and serum levels of polyunsaturated fatty acids omega-3 and omega-6 among college students from Northern Mexico

Introducción: estudios previos sugieren que un bajo consumo de ácidos grasos poliinsaturados (AGPI) omega-3 y razón omega-6/omega-3 alta, así como niveles séricos bajos, se asocian con trastornos depresivos, sin embargo, los resultados no son concluyentes. Objetivos: evaluar los niveles séricos de AGPI omega-3 (ácido eicosapentaenoico [EPA], docosahexaenoico [DHA], alfalinolenico [ALA]) y la razón omega-6 (ácido araquidónico [AA])/EPA, en relación a los síntomas depresivos en universitarios del norte de México. Material y métodos:estudio transversal que incluyó 60 participantes (18 a 24 años de edad) de ambos sexos, con determinaciones séricas de EPA, DHA, ALA y AA, quienes respondieron la escala de depresión del Centro de Estudios Epidemiológicos (CES-D) validada para estudiantes mexicanos. La relación de los AGPI omega-3 y omega-6 con los síntomas depresivos se evaluó con modelos de regresión lineal. Resultados: los niveles séricos de EPA, DHA y razón EPA/DHA no se correlacionaron con síntomas depresivos, un incremento en ALA sérico se correlacionó con menos síntomas depresivos antes y después de ajustar por confusores; sin embargo, los resultados no fueron estadísticamente significativos. En mujeres, la escala CES-D incrementó 5,5 puntos (p = 0,57) por 1% de incremento en EPA y disminuyó 6,7 puntos (p = 0,39) por 1% de incremento en ALA. Conclusiones: nuestros resultados no confirman la asociación entre los niveles séricos de AGPI omega-3 y razón omega-6/omega-3 con síntomas depresivos. La correlación negativa del nivel sérico de ALA con síntomas depresivos necesita ser confirmada en estudios de seguimiento (AU)

Introduction: Previous studies suggest that low consumption as well as low serum levels of polyunsaturated fatty acids (PUFA) omega-3 and a high omega-6/omega-3 ratio may be implicated in the etiology of depressive disorders, however, epidemiologic evidence is inconclusive. Objective: To assess the relationship of serum levels of omega-3 fatty acids (docosahexaenoic [DHA], eicosapentaenoic [EPA], alpha-linolenic fatty acid [ALA]) and the omega-6 (arachidonic acid [AA])/EPA ratio with depressive symptoms among Mexican college students. Material and methods: A cross-sectional study that included 60 male and female participants (ages 18 to 24 years) with serum levels of EPA, DHA, ALA and AA. Depressive symptoms were ascertained with the Center for Epidemiologic Studies Depression (CES-D) scale validated for Mexican students. Linear regression was used to assess the relationship between depressive symptoms and serum PUFA omega-3 and omega-6. Results: Serum levels of EPA, DHA and EPA/DHA ratio were not related to depressive symptoms, high serum ALA was related with lower depressive symptoms before and after covariate adjustment; however, these results were not statistically significant. Among women, 1% increase in EPA resulted in 5.5. (p = 0.57) increase in the depressive scale scores while 1% increase in ALA resulted in 6.7 decrease (p = 0.39) in the scores. Conclusions: Our results did not confirm the relationship of serum levels of PUFA omega-3 and omega-6/omega-3 ratio with depressive symptoms; the negative correlation of serum ALA with depressive symptoms remains to be confirmed in prospective studies (AU)

Quality of reproductive healthcare for adolescents: A nationally representative survey of providers in Mexico.

OBJECTIVE: Adolescents need sexual and reproductive health services but little is known about quality-of-care in lower- and middle-income countries where most of the world's adolescents reside. Quality-of-care has important implications as lower quality may be linked to higher unplanned pregnancy and sexually transmitted infection rates. This study sought to generate evidence about quality-of-care in public sexual and reproductive health services for adolescents. METHODS: This cross-sectional study had a complex, probabilistic, stratified sampling design, representative at the national, regional and rural/urban level in Mexico, collecting provider questionnaires at 505 primary care units in 2012. A sexual and reproductive quality-of-healthcare index was defined and multinomial logistic regression was utilized in 2015. RESULTS: At the national level 13.9% (95%CI: 6.9-26.0) of healthcare units provide low quality, 68.6% (95%CI: 58.4-77.3) medium quality and 17.5% (95%CI: 11.9-25.0) high quality reproductive healthcare services to adolescents. Urban or metropolitan primary care units were at least 10 times more likely to provide high quality care than those in rural areas. Units with a space specifically for counseling adolescents were at least 8 times more likely to provide high quality care. Ministry of Health clinics provided the lowest quality of service, while those from Social Security for the Underserved provided the best. CONCLUSIONS: The study indicates higher quality sexual and reproductive healthcare services are needed. In Mexico and other middle- to low-income countries where quality-of-care has been shown to be a problem, incorporating adolescent-friendly, gender-equity and rights-based perspectives could contribute to improvement. Setting and disseminating standards for care in guidelines and providing tools such as algorithms could help healthcare personnel provide higher quality care.

Inicio de relaciones sexuales con penetración y factores asociados en chicos y chicas de México de 14-19 años de edad con escolarización en centros públicos / Sexual intercourse debut and associated factors in Mexican students aged 14-19 years in public schools

Objetivo: Estimar la edad promedio de inicio de las relaciones sexuales con penetración (IRSP) y los factores familiares e individuales asociados en chicos y chicas de 14-19 años escolarizados en centros públicos de las 32 entidades de México, en 2007. Métodos: Estudio transversal realizado en una muestra representativa de 9893 estudiantes de 14-19 años de edad. La información se recolectó utilizando un cuestionario autoadministrado, anónimo y voluntario. Se estimaron modelos de regresión logística para obtener odds ratio (OR) e intervalos de confianza del 95% (IC95%) por categorías: sin IRSP, IRSP a los 10-15 años años e IRSP a los 16-19 años. Resultados: El promedio de edad nacional para el IRSP fue de 16 años (IC95%: 15,5-16,1). En los chicos, la media de edad al IRSP fue de 15 años (IC95%: 15,88-16,11), y en las chicas fue de 16 años (IC95%: 15,26-15,42). Factores asociados a IRSP en chicos: nivel socioeconómico desfavorecido (OR=0,66; IC95%: 0,46-0,94), vivir con los padres (OR=0,65; IC95%: 0,56-0,75), comunicación ofensiva menor entre padres/madres e hijos/as (OR=0,66; IC95%: 0,57-0,77)¸ autoestima social alta (OR=1,68; IC95%: 1,35-1,77). Factores asociados a IRSP en chicas: creencias de género tradicionales (OR=0,49; IC95%: 0,32-0,74), sintomatología depresiva alta (OR=1,88; IC95%: 1,19-2,99), autoestima familiar alta (OR=0,50; IC95%: 0,38-0,65). Conclusiones: En México, el IRSP se presenta a edad más temprana en los chicos. Además, los hallazgos del presente estudio demuestran que la edad de IRSP y los factores asociados son diferentes en los chicos y las chicas. Las creencias de género y socioculturales influyen de manera importante en la edad de IRSP (AU)

Objective: To estimate the mean age of sexual intercourse debut (SID) and associated family and individual factors in 14-19-year-olds of both sexes in the 32 states of Mexico in 2007. Methods: A cross-sectional study was conducted of a representative sample of 9,893 students aged between 14 and 19 years old. The data were collected through a self-administered, anonymous and voluntary questionnaire. Logistic regression models were used to estimate odds ratios (OR) with 95% confidence intervals (95%CI) by category: no SID, SID at 10-15 years and SID at 16-19 years. Results: The national mean age of SID was 16 years, being 15 years for boys (95%CI: 15.88-16.11) and 16 years for girls (95%CI: 15.26-15.42). Factors associated with SID in boys were disadvantaged socioeconomic level (OR=0.66; 95%CI: 0.46-0.94), living with parents (OR=0.65; 95%CI: 0.56-0.75), less offensive communication between parents and boys/girls (OR=0.66; 95%CI: 0.57-0.77), and high social self-esteem (OR=1.68; 95%CI: 1.35-1.77). Factors associated with SID in girls were traditional gender beliefs (OR=0.49; 95%CI: 0.32-0.74), high depressive symptoms (OR=1.88; 95%CI: 1.19-2.99), and high family self-esteem (OR= 0.50; 95%CI: 0.38-0.65). Conclusions In Mexico, SID occurred early in boys. In addition, the findings of this study show that in Mexico, the age of SID and associated factors differ in boys and girls. The age of SID is strongly influenced by gender and cultural beliefs (AU)

[Individual and family factors associated with depressive symptomatology in adolescents from public schools of Mexico]. / Factores individuales y familiares asociados con sintomatología depresiva en adolescentes de escuelas públicas de México.

OBJECTIVE: To estimate the prevalence of depressive symptoms (DS) and to explore associated individual and family factors in high-school students from public schools of Mexico. MATERIALS AND METHODS: Cross-sectional study of a representative sample of 9 982 students aged between 14 and 19 years. Logistic regression models were used to estimate odds ratio (OR) with 95% confidence interval (CI95%). RESULTS: 27% of students presented DS, with higher proportion among women (34%) than among men (18%). Factors associated with DS were being female (OR=2.25 CI95% 1.86-2.71); low self-esteem (OR=2.77 CI95% 2.41 -3.19); consuming alcohol (OR= 1.72 CI95% 1.46-2.02), consuming tobacco (OR= 1.57 CI95% 1.31-1.88), consuming illegal drugs (OR=1.63 CI95% 1.29-2.05), domestic violence (OR=2.05 CI95% 1.77-2.39), and low communication between parents and their children (OR=1.78 CI95% 1.59-2.00). CONCLUSIONS: Depressive symptomatology among high-school students in Mexico is a public health issue.There is a need for intervention programs aimed at tackling the associated risk factors.
