Objective. To describe the coverage and targeting of Social Food Assistance Programs (SFAP) in Mexico. Materials and methods. Data were obtained from 9 137 households of the Halfway National Health and Nutrition Survey 2016 (Ensanut MC 2016) who receive SFAP. The distribution of the SFAP by place of residence, index of socioeconomic status and SFAP relevance were analyzed. Results. 44% of households receive some SFAP, with a higher concentration in indigenous households (70%), a very low socioeconomic level (70%), and moderate and severe food insecurity. The SFAP with the greatest coverage were Prospera (21%), Liconsa (9%), School Breakfasts Program (17%) and the Support Program for Older Adults; of these the best-focused program was Prospera. Conclusions. It is necessary to review the resources of the programs and direct them to the population with greater deficiencies and greater nutritional vulnerability.

Objetivo. Explorar percepciones de proveedores de salud y beneficiarias del Programa Oportunidades sobre la práctica de actividad física durante el embarazo y posparto, e identificar características de la consejería sobre el tema en el primer nivel de atención en salud. Material y métodos. Estudio de métodos mixtos que forma parte de una intervención en nutrición del Programa Oportunidades. La información cualitativa se colectó por entrevista (50 mujeres; 34 proveedores de salud) y se obtuvo información cuantitativa a partir de un cuestionario (n=88 mujeres; n=64 proveedores; n=111 observaciones de consulta). Resultados. Se documentaron barreras a) individuales: falta de tiempo y de apoyo social; b) socioculturales: prejuicios de pares y familiares, y falta de instructores, y c) ambientales: falta de espacios físicos seguros y apropiados. 38% de las mujeres reporta haber recibido consejería sobre el tema versus 63.4% de proveedores que reportan haberla dado (p=0.002). Conclusiones. Urgen capacitación a proveedores y promoción de la actividad física que eliminen los prejuicios asociados al tema durante el embarazo y posparto.

Objective. This study aims to explore adolescents’ intentions related to the early formation of a family. Materials and methods. We administered a survey to students in eight schools in Morelos and Mexico City, in 2010. We analyzed intentions of marrying or having a child and fitted an exploratory path model to assess predictors of the intentions of having a child before the age of 20 (n=2974). Results. Around 77% of adolescents expect to have their first child at 20 years or later; 21% show ambivalence or incongruence regarding this, whereas 2% expect to have a child before the age of 20. Parents’ expectations for their child’s education influence the importance that adolescents give to education. The latter promotes the idea of postponing childbearing until 20 years or later (β=0.13). Conclusions. In order to prevent early pregnancies, interventions and programs should encourage the construction of personal and professional goals.

OBJETIVO: El estudio de patrones dietarios ha demostrado su utilidad en la investigación para entender la relación entre dieta y salud. En este trabajo se buscó identificar patrones de dieta en adolescentes mexicanas a través de dos métodos estadísticos. MATERIAL Y MÉTODOS: Se llevó a cabo un estudio transversal con 477 mujeres de 12-19 años (Encuesta Nacional de Nutrición 1999). Se caracterizaron patrones dietarios por medio de análisis de factores y de conglomerados. RESULTADOS: Se identificaron tres patrones dietarios por conglomerados "urbano"[U], 9.7%, "rural" [R], 47.9% y "occidental" [O], 42.3%. Por aporte energético, los principales grupos de alimentos en el patrón [U] fueron el maíz (20%) e industrializados (17%). En el patrón [R] predominaron el maíz (48%), los alimentos de trigo y leguminosas (~6% c/u). En [O] el trigo (19%) y las carnes rojas (11%). Asimismo, se identificaron cuatro patrones dietarios por el método de factores. En el factor uno predominaron los productos de trigo, postres, botanas y carnes. El factor dos se caracterizó por consumo alto de lácteos bajos en grasas y cereal de caja. El factor tres se caracterizó por consumo alto de refrescos e industrializados. En el factor cuatro predominaron el café, los dulces y las leguminosas. CONCLUSIONES: Se identificaron patrones dietarios en adolescentes mexicanas y los resultados de los dos métodos utilizados fueron comparables.OBJECTIVE: To identify dietary patterns in Mexican female adolescents by two statistic methods. MATERIAL AND METHODS: Cross-sectional study of 477 women 12 to 19 years of age -National Nutrition Survey, 1999. Dietary patterns were obtained by factor and cluster analyses. RESULTS: Three dietary patterns were identified by cluster analysis: "Urban-poor" [U] (9.7%), "Rural" [R] (47.9%), and "Western" [W] (42.3%). Pattern [U] was characterized by a sizeable intake of maize products (20%) and industrialized foods (17%). Maize products and legumes predominated in the [R] pattern (48% and 6% of total energy, respectively). In the [W] pattern, wheat products and meat contributed 19% and 10.6% of energy, respectively. Moreover, four dietary patterns were identified through factor analysis. Factor 1 had a positive loading factor on wheat products, desserts, and meat. Factor 2 was characterized by a high consumption of low-fat dairy and low-fiber breakfast cereals. Factor 3 had a high loading for sweetened beverages and industrialized foods. Factor 4 had a moderate loading on maize products and legumes. CONCLUSION: We identified dietary patterns in Mexican adolescent girls by two methods, obtaining comparable results between methods.
