Dietary patterns, overweight and obesity from 1961 to 2011 in the socioeconomic and political context of Argentina.

To analyse the changes in eating patterns in Argentina from 1961 to 2011, and to assess changes in overweight and obesity in their socioeconomic and political context, we performed a hierarchical cluster analysis. We used the information from Food Balance Sheets of the United Nations Food and Agriculture Organisation to identify dietary patterns of apparent consumption. Years were grouped into five patterns. The food group with the highest apparent consumption was cereals (30% of total kcal/person/day) although this decreased slightly. Meats were second and their contribution decreased by 12%. The following foods contribution increased during the period: Sugar and milk by 2% and vegetable oils by 6%. The changes observed in the number of kcal/person/day were in line with changes in real wage, and coincided with economic and political crises that Argentina experienced during that period. Changes in eating patterns allow us to interpret that they relate to the increase in overweight and obesity.

[Construction and validation of an instrument to assess primary care level patient satisfaction]. / Construcción y validación de un instrumento para medir la satisfacción de los pacientes del primer nivel de atención médica en la Ciudad de México.

OBJECTIVE: To develop an instrument to assess the satisfaction of patients using health services at the first care level of the city of Mexico (SSA), adapted to the socio-cultural characteristics of the population, and to examine its reliability and validity. METHODS: The instrument reagents were designed using the natural semantic networks technique. The dimensions used have been determined from the literature. Participants included 230 adults with type 2 diabetes attending eight SSA health centers. Subsequently, intelligibility was determined by conducting a pilot, then the construct validity of the instrument by means of exploratory factor analysis was evaluated and its internal consistency was determined by calculating Cronbach's alpha. RESULTS: The questionnaire is composed of six factors with a Likert-type scale. Its consistency showed a Crombach´s alpha of 0.94. The factor structure included 29 reagents that correlated with the six dimensions with factorial loads>0.581 that explained 66.8% of the total variance. CONCLUSIONS: The patient satisfaction questionnaire incorporates the sociocultural characteristics of the target population and has an adequate level of validity and reliability and is quick and easy in application.

[Type 2 Diabetes and Dietary Patterns 1961 to 2009: Some Social Determinants in Mexico]. / Diabetes tipo 2 y patrones de alimentación de 1961 a 2009: algunos de sus determinantes sociales en México.

In order to analyze whether the increase in mortality from diabetes in Mexico is related to changes in eating patterns over the period 1961 to 2009, and if they in turn could be explained in the Mexican socioeconomic context, we conducted an ecological study with information from the Food Balance Sheets FAO. A cluster analysis was performed to shape eating patterns (three) and some socioeconomic variables were analyzed. It was observed that the energy derived from cereals and legumes (beans) was significantly reduced, and simultaneously, energy from sugars, animal foods, and vegetable fats had a significant increase. Various socioeconomic conditions may have favored changes in diet and increased mortality from diabetes. These conditions are: trade liberalization, low growth, rising inequality and informal work, declining agriculture, falling real wages in relation to the value of what is called the "basic food and non-food baskets", increasing prices of healthy food,low cost of processed foods and beverages, and the lack of control in the food market.

[The nutrition transition and the double burden of malnutrition: changes in dietary patterns 1961-2009 in the Mexican socioeconomic context]. / La transición alimentaria y la doble carga de malnutrición: cambios en los patrones alimentarios de 1961 a 2009 en el contexto socioeconómico mexicano.

The purpose of this study was to identify whether there were changes in the composition of dietary patterns from 1961 to 2009, if food patterns by income level and the increase in the price of certain basic foods of the diet in the socioeconomic Mexican context, could explain the nutrition transition and the double burden of malnutrition. We conducted an ecological study with data from FAO balance sheets. To construct eating patterns cluster analysis was performed. Engel curves were developed with data from the 2012 INEGI ENGH survey and evolution of the relative price of some foods was calculated. The diet was defined in three dietary patterns. The increase in the total availability of energy increased from 2316 kcal/person/day in 1961 to 3146 in 2009. Dietary pattern modifications are in line with the nutrition transition and the double burden of malnutrition. It was observed that the energy derived from cereals and from legume (common beans) was significantly reduced, and simultaneously, the energy from sugars, animal foods and vegetable fats had a dramatic increase. Spending on food was differential according to income level. Malnutritionis mediated by the unequal distribution of income, the relatively low cost of energy-dense foods, the increased cost of nutritious foods, and limited support to agriculture.

Youth who neither study nor work: mental health, education and employment.

OBJECTIVE: Limited educational and job opportunities for youth has led to a phenomenon termed NEET (not in education, employment or training). The objective is to estimate the prevalence of psychiatric disorders, substance use and suicidal behavior in youth classified as NEET and to compare with those who study only, work only or do both. MATERIAL AND METHODS: 3 005 12-to-17 year-olds in Mexico City were evaluated in 2005 with the Composite International Diagnostic Interview. Descriptive and logistic regression analyses considered the multistage weighted sample design. RESULTS: NEET youth as well as those who work only or study and work simultaneously have greater odds of psychiatric disorder, substance use and suicidal behavior compared to those who study exclusively even after controlling for social disadvantage. CONCLUSION: Vulnerability is not circumscribed to NEET adolescents, but to all teens who are not exclusive students. Supporting youth to continue studying exclusively may buffer negative mental health outcomes.

Undiagnosed prediabetes in Mexican adolescents under poverty in contexts affected by collective violence: A clinical comparison among health services users and hidden population.

Introduction: The epidemiological pattern of prediabetes in adolescents is understudied. In Mexico, adolescents are exposed to social adversity conditions, including poverty and violence. Therefore, understanding their clinical profiles and how the social determinants of health impose barriers to access to health services is important to address detection, in those who, by their vulnerability, remain a hidden population. Aim: This study aimed to describe undiagnosed prediabetes in Mexican adolescents under poverty in violent contexts and to compare the clinical features among health services users and hidden population. Methods: This cross-sectional study included 371 adolescents from difficult access locations in violent contexts. Poverty, lack of health services access, and perceived vulnerability were determined in all samples. Endocrine markers (BMI, HOMA-IR, HbA1c, and cortisol) were measured in those with high violence perception. Results: A total of 61.7% of the adolescents had a suburban grid and urban cluster residence, and 77.7-85.7% of them belonged to locations where 35-50% of their population lived below the poverty line. In total, 40-75% had a lack of 10-20% access to health services, and 18.8% had a high perceived vulnerability due to collective violence and were screened. Overall, 61.9% of respondents were newly diagnosed with prediabetes and showed the worst HbA1c (p = 0.001) compared to the health services subsample, which showed the highest BMI (p = 0.031) and insulin resistance (p = 0.025). Conclusion: There is a prediabetes hidden population living in violent contexts under poverty. These social determinants promote poor outcomes in perceived vulnerability and endocrine response and represent barriers to access to health services.

Variation in incidence of type 2 diabetes mellitus: time series of Mexican adolescents.

PURPOSE: To study temporal changes in the cumulative incidence (CI) of type 2 diabetes mellitus during early and late adolescence from 2003 to 2013. METHODS: This was an ecologic, analytical study of trends over time. Data were weekly reports of new cases (General Directorate of Epidemiology). Specific CI was calculated and standardized by age using the direct method (WHO). Autoregressive Integrated Moving Average models offering a better fit to the observed series were calculated and controlled by intentional screening. Structural break point analysis was performed. RESULTS: The CI was lower in younger adolescents than in older adolescents. In early adolescence, the incidence was similar in both sexes and stable over time [Autoregressive Integrated Moving Average female: (2,0,2)(0,0,0), male: (1,0,1)(0,0,0); P < .001], whereas in late adolescence, the female incidence was higher than the male incidence and showed a linear increase [female: (1,1,2)(1,0,0), male: (1,0,1)(0,0,0); P < .001)]. The female series showed two structural break points, in 2010 and 2012. The male early adolescent series showed one break point in 2011. CONCLUSIONS: Although there was an increase in the CI of type 2 diabetes mellitus during the study period, only the female late adolescence series showed an epidemiologically significant linear trend. There was also a brief, limited rise between 2010 and 2012 that affected all adolescents. This suggests that the disease may be triggered by specific events.

A life-course approach to early-onset of diabetes mellitus: Probable contribution of collective violence in Mexico.

Type 2 diabetes mellitus (T2DM) is a growing health problem among the pediatric population in the world, and particularly in Mexico. Official data in Mexico reported that during the period from 2003 to 2013 there was an increase in the cumulative incidence among older adolescents between 2010 and 2012, which decreased to the usual measures in 2013. All these variations occurred in a period in which collective violence permeated all levels of Mexican society. It can be argued that there might be a relationship between the two phenomena. This is an ecologic analytical study of trends over time comprising older adolescents (15-19 year olds). T2DM cumulative incidence and mortality rates attributable to violent death (VD) were standardized by direct method according to the World Health Organization. Data were sourced from nationwide official reports. Time series analysis was performed with ARIMA models and significant predictors. The disease ecology analysis was done using cluster analysis. Using significant predictors with ARIMA models, we found that the male VD mortality rates series could forecast 63.1% of the temporal variability of the cumulative incidence of T2DM series. Geographically, states with higher rates of violence also showed a higher incidence of T2DM. These data suggest that collective violence may make some contribution to the early onset of T2DM among adolescents, particularly in those regions most affected by violence. These findings can be conducive to opening new lines of research to explore the relationship between variables at the individual level and the clinical implications.

Development and psychometric properties of the Subtle Gender-Based Violence Among Medical Residents Assessment Scale (SGEVRA) / Desarrollo y propiedades psicométricas de la Escala de Violencia Sutil de Género en Médicos Residentes (SGEVRA)

Abstract Introduction Medical residents (MR) are an important pillar for a future effective health system. As such, it is important to study all the factors throughout their training that may influence their professional development, like gender-based violence (GV). Objetive To design and evaluate the psychometric proprieties of subtle GV among medical residents' assessment scale (SGEVRA). Method The design was carried out in two phases: (1) in the qualitative phase, three focus groups were interviewed to obtain information about GV during medical training; and (2) in the quantitative phase, the information was incorporated into the instrument and the psychometric properties were tested. Results A total of 1,645 medical residents (MRs) completed the instrument. Exploratory factor analysis led to a final two factor model comprised of 31 items that explained 74.9% of the variance. The factors were labelled as gender discrimination (factor 1) and sexual violence (factor 2); both demonstrated high internal consistency using Cronbach's alpha (factor 1: .987; factor 2: .935). Discussion and conclusion The SGEVRA is a brief, valid, and reliable instrument for assessing subtle GV among MR.

Resumen Introducción Los residentes médicos (MR) son un pilar importante para un futuro sistema de salud efectivo. Por ello, es importante estudiar todos los factores a lo largo de su capacitación que puedan influir en su desarrollo profesional, como la violencia de género (GV). Objetivo Diseñar y evaluar las propiedades psicométricas de la Escala de Violencia Sutil de Género en médicos residentes (SGEVRA, por sus siglas en inglés). Método El diseño se realizó en dos fases: (1) cualitativa: se entrevistó a tres grupos focales para obtener información sobre la VG durante la capacitación médica; y (2) cuantitativa, donde la información se incorporó al instrumento y se evaluaron las propiedades psicométricas. Resultados 1,645 residentes médicos (MR) completaron el instrumento. El análisis factorial exploratorio condujo a un modelo final de dos factores compuesto por 31 reactivos que explicaron el 74.9% de la varianza. Los factores fueron etiquetados como discriminación de género (factor 1) y violencia sexual (factor 2); ambos demostraron una alta consistencia interna con el alfa de Cronbach (factor 1: .987; factor 2: .935). Discusión y conclusión SGEVRA es un instrumento breve, válido y confiable para evaluar GV en MR.

La transición alimentaria y la doble carga de malnutrición: cambios en los patrones alimentarios de 1961 a 2009 en el contexto socioeconómico mexicano

El propósito de este trabajo fue identificar si existieron cambios en la composición de los patrones alimentarios de 1961 a 2009, si el gasto en algunos alimentos por nivel de ingresos y el aumento en el precio de ciertos alimentos básicos de la dieta en el contexto socioeconómico mexicano, podrían explicar la transición alimentaria y la doble carga de malnutrición. Se llevó a cabo un estudio ecológico con la información de las Hojas de Balance de la FAO. Para conformar los patrones alimentarios se realizó análisis de conglomerados. Además, con los datos de la Encuesta Nacional de Ingresos y Gastos en los Hogares 2012 del Instituto Nacional de Estadística y Geografía se construyeron curvas de Engel para calcular la evolución del precio relativo de algunos alimentos. La dieta se definió en tres patrones alimentarios. La disponibilidad total de energía aumentó de 2316 kcal/persona/ día en 1961 a 3146 en 2009. Las modificaciones del patrón alimentario están en consonancia con la transición alimentaria y nutricional y con la doble carga de malnutrición. Se observó que la energía derivada de los cereales y la proveniente de las leguminosa (frijol) se redujo considerablemente, y de manera simultánea la energía procedente de azúcares, alimentos de origen animal y grasas vegetales tuvieron un aumento notable. El gasto en alimentos fue diferencial de acuerdo al nivel de ingresos. La malnutrición está mediada por la inequitativa distribución del ingreso, el bajo costo relativo de los alimentos ricos en energía, el encarecimiento de alimentos nutritivos y el escaso apoyo a la agricultura.

OBJETIVO: Oportunidades educativas y laborales limitadas para los jóvenes han dado lugar al fenómeno de adolescentes que no estudian ni trabajan (NINIs). El objetivo es estimar la prevalencia de trastornos psiquiátricos, consumo de sustancias y conducta suicida en adolescentes NINIs y compararlos con adolescentes que estudian exclusivamente, trabajan exclusivamente y quienes estudian y trabajan. MATERIAL Y MÉTODOS: 3 005 adolescentes entre 12 y 17 años de edad fueron evaluados en 2005 con la Entrevista Internacional Psiquiátrica Compuesta en una encuesta multietápica, estraficada y representativa del Distrito Federal y municipios conurbados. RESULTADOS: Los NINIs, quienes trabajan, y quienes estudian y trabajan tienen mayor riesgo de trastornos psiquiátricos, consumo de sustancias y conducta suicida en comparación con aquellos que estudian exclusivamente. CONCLUSIÓN: La vulnerabilidad no se circunscribe a los NINIs sino a todos los que no son estudiantes exclusivamente. Apoyar a los jóvenes para que estudien podría beneficiar su salud mental.
