Background: In Mexico, stunting and anemia have declined but are still high in some regions and subpopulations, whereas overweight and obesity have increased at alarming rates in all age and socioeconomic groups. Objective: The objective was to describe the coexistence of stunting, anemia, and overweight and obesity at the national, household, and individual levels. Design: We estimated national prevalences of and trends for stunting, anemia, and overweight and obesity in children aged ,5 y and in school-aged children (5-11 y old) and anemia and overweight and obesity in women aged 20-49 y by using the National Health and Nutrition Surveys conducted in 1988Surveys conducted in , 1999Surveys conducted in , 2006Surveys conducted in , and 2012 With the use of the most recent data (2012), the double burden of malnutrition at the household level was estimated and defined as the coexistence of stunting in children aged ,5 y and overweight or obesity in the mother. At the individual level, double burden was defined as concurrent stunting and overweight and obesity in children aged 5-11 y and concurrent anemia and overweight or obesity in children aged 5-11 y and in women. We also tested if the coexistence of the conditions corresponded to expected values, under the assumption of independent distributions of each condition. Results: At the household level, the prevalence of concurrent stunting in children aged ,5 y and overweight and obesity in mothers was 8.4%; at the individual level, prevalences were 1% for stunting and overweight or obesity and 2.9% for anemia and overweight or obesity in children aged 5-11 y and 7.6% for anemia and overweight or obesity in women. At the household and individual levels in children aged 5-11 y, prevalences of double burden were significantly lower than expected, whereas anemia and the prevalence of overweight or obesity in women were not different from that expected. Conclusions: Although some prevalences of double burden were lower than expected, assuming independent distributions of the 2 conditions, the coexistence of stunting, overweight or obesity, and anemia at the national, household, and intraindividual levels in Mexico calls for policies and programs to prevent the 3 conditions.

Objetivos. Describir la prevalencia de hipertensión arterial (HTA) en adultos, el porcentaje de ellos con diagnóstico previo y la proporción que tuvo un control adecuado. Ma­terial y métodos. Se midió la tensión arterial a 8 352 adultos que participaron en la Ensanut MC 2016. Se clasificó como hipertensos a quienes reportaron haber recibido previamente el diagnóstico de HTA, o presentaban cifras de tensión arterial sistólica (TAS) ≥140mmHg o tensión arterial diastólica (TAD) ≥90mmHg. Se consideró tensión arterial controlada cuando la TAS <140mmHg y la TAD <90mmHg. Resultados. La prevalencia de HTA en adultos fue de 25.5%, de los cuales, 40.0% desconocían tener HTA. De los hipertensos que tenían diagnóstico previo de HTA y que re­cibían tratamiento farmacológico (79.3%), 45.6% tuvo tensión arterial bajo control. Conclusiones. Un alto porcentaje de adultos desconocen tener HTA y de ellos casi la mitad tiene un control inadecuado. Debería evaluarse la pertinencia de los actuales programas de diagnóstico de HTA y la efectividad de sus estrategias de control.

High proportions of Mexicans consume diets that do not meet recommendations. Breastfeeding and complementary feeding diverged from recommendations, intakes of discretionary foods were high, and the prevalence of nutrient inadequacies and age groups not meeting intake recommendations of basic food groups were also high. The results are consistent with the high prevalence of the double burden of malnutrition and are useful to design food and nutrition policies.

The intake of vitamins among Mexicans is inadequate overall. Information collected by ENSANUT can help target food assistance programs and develop strategies to prevent vitamin deficiencies.

Objective. To describe in a national sample 1) the prevalence, awareness, treatment and control of dyslipidemias 2) the prevalence of dyslipidemias through previous national surveys. Materials and methods. We analyzed data of the National Health and Nutrition Survey 2012, a representative cross-sectional study. Serum samples of 9 566 adults ≥20 years old with fasting ≥8 hours were analyzed for lipid fractions. Age-adjusted prevalences were calculated, by sociodemographic variables. Prevalence of awareness, treatment and control was estimated. A description of the dyslipidemia prevalence reported in previous surveys is reported. Results. Hypoalphalipoproteinemia and elevated LDL-C are the most prevalent dyslipidemias in Mexican adults. One in four adults had hypercholesterolemia at the moment of the interview without previous diagnosis. Awareness, treatment and control of dyslipidemia were 12.6, 3.7 and 3.1%, respectively. Conclusions. Dyslipidemias are the most prevalent risk factor for cardiovascular diseases in Mexico. Public policies to increase awareness, access to therapy and sustained control are urgently needed.

Purpose of reviewThere are today 11 mega-countries with more than 100 million inhabitants. Together these countries represent more than 60% of the world's population. All are facing noncommunicable chronic disease (NCD) epidemic where high cholesterol, obesity, diabetes, and cardiovascular diseases are becoming the main public health concerns. Most of these countries are facing the double burden of malnutrition where undernutrition and obesity coexist, increasing the complexity for policy design and implementation. The purpose of this study is to describe diverse sociodemographic characteristics of these countries and the challenges for prevention and control in the context of the nutrition transition.Recent findingsMega-countries are mostly low or middle-income and are facing important epidemiologic, nutrition, and physical activity transitions because of changes in food systems and unhealthy lifestyles. NCDs are responsible of two-thirds of the 57 million global deaths annually. Approximately, 80% of these are in low and middle-income countries. Only developed countries have been able to reduce mortality rates attributable to recognized risk factors for NCDs, in particular high cholesterol and blood pressure.SummaryMega-countries share common characteristics such as complex bureaucracies, internal ethnic, cultural and socioeconomic heterogeneity, and complexities to implement effective health promotion and education policies across population. Priorities for action must be identified and successful lessons and experiences should be carefully analyzed and replicated.
