Background/Aims: It was the aim of this study to evaluate the relationships between sweetened beverage (SB) consumption and the following indicators of overweight/fatness among Mexican adolescents: body mass index, body composition and body fat distribution. Methods: We performed a cross-sectional analysis of data from adolescents participating in the baseline assessment of the Health Workers Cohort Study. Information on sociodemographic conditions, sexual maturation, dietary patterns and physical activity was collected via self-administered questionnaires. SB consumption was evaluated through a validated semiquantitative food frequency questionnaire. Anthropometric measures were assessed with standardized procedures. The associations of interest were evaluated by means of multivariate regression and logistic regression models. Results: A total of 1,055 adolescents, 10–19 years old (mean age 14.5 ± 2.5 years), were evaluated. The overweight/obesity prevalence was 31.6% among girls and 31.9% among boys. We found that for each additional SB serving consumed daily, the subject’s body mass index increased by on average 0.33 (p < 0.001). Subjects consuming 3 daily servings of SB face a 2.1 times greater risk of proportionally excess body fat than those who consume less than 1 SB a day. Conclusions: Our data support the hypothesis that the consumption of SB increases the risk of overweight and/or obesity and encourages excess body fat and central obesity in Mexican adolescents.

ObjectiveTo evaluate the prevalence of weight-loss practices among university students from Tlaxcala, Mexico.MethodsA cross-sectional study of 2,651 university students was conducted. Logistic regression tests were used to estimate the probability of students trying to lose weight and successfully achieving weight loss.ResultsNearly 40% of students attempted to lose weight, though only about 7% lost more than 10% of their body weight and maintained this weight loss during the time of the study. The methods used most were exercise and dieting, and those who dieted were more successful at losing weight.ConclusionsThe high prevalence of weight-loss attempts and the poor outcomes with these weight-loss methods among this sample of university students is a public health concern. Universities should provide students with healthy weight-control approaches, which include offering information about healthier lifestyles, access to healthy food and opportunities to be physically active.

Objetivo. Cuantificar el abasto en farmacia y el nivel de surtimiento de medicamentos en las unidades de especialidades médicas de enfermedades crónicas (UNEMES-EC) de México. Material y métodos. Los indicadores de abasto y surtimiento se midieron en 30 de 86 UNEMES-EC existentes en el país. El abasto de medicamentos se registró mediante una lista de cotejo que incluía 17 medicamentos básicos relacionados con la atención de diabetes mellitus, hipertensión y sobrepeso/obesidad. La información sobre surtimiento de recetas procede de un cuestionario aplicado directamente a 1 200 usuarios. Resultados. Sólo 13.3% de las unidades reportó abasto completo de medicamentos esenciales y dicho abasto fue más frecuente en aquellas unidades con servicio tercerizado de farmacia. Del total de pacientes entrevistados, 35% alguna vez tuvo que comprar medicamentos con recursos propios. Conclusión. Las UNEMES-EC deben mejorar su abasto de medicamentos y el surtimiento completo de recetas para evitar que sus usuarios incurran en gastos de bolsillo.

Additional efforts are required to monitor accredited clinics' performance in order to maintain both metabolic control and clinical assessment of patients.

Objetivo. Describir y cuantificar los servicios prestados en hospitales de la Secretaría de Salud a pacientes con seguridad social o que habitan en entidades distintas a la del hospital del que egresaron. Material y métodos. Utilizando el Sistema Automatizado de Egresos Hospitalarios, los pacientes se clasificaron, según su residencia, en locales o foráneos; y por tipo de aseguramiento, en derechohabientes o no derechohabientes. Se calculó la frecuencia de servicios otorgados y se analizaron las características diferenciales de los pacientes y los servicios. Resultados. De los pacientes 5.6% fueron foráneos. En los Institutos Nacionales de Salud este porcentaje alcanzó 50%. Sólo 1.7% de los pacientes registraron ser derechohabientes. Las características sociodemográficas y del perfil de servicios son claramente distinguibles entre pacientes foráneos y derechohabientes y aquellos sin estos atributos. Discusión. Independientemente del carácter segmentado y fragmentado del Sistema Nacional de Salud, existe un proceso de intercambio de servicios entre proveedores.
