To document the energy and nutrient intake of Mexican preschool children using data from the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006).
Dietary data from 3 552 children less than 5 years old collected through a semi-quantitative food frequency questionnaire were analyzed. Energy and nutrient daily intakes and adequacies were calculated. Comparisons were made by geographic region, residence locality, and socioeconomic status.
The Mexico City region showed the highest energy (103.2%), carbohydrate (109.9%), and fat (110.1%) adequacies. The highest proportion of preschoolers with energy and micronutrients inadequacy (adequacy

The purpose of this study is to quantify the prevalence and distribution of anemia among women of childbearing age (12 to 49 years) participating in the 1999 National Nutrition Survey (NNS-1999).
The survey had a probabilistic design and was representative at the national level, of urban and rural areas and four regions: North, South, Center, and Mexico City. Hemoglobin concentration was determined in capillary blood samples using a portable photometer (HemoCue), in 17,194 women, 697 of whom were pregnant.
The overall prevalence of anemia was 27.8% in pregnant women and 20.8% in non-pregnant women. Higher prevalences were observed in rural as compared to urban areas, both in pregnant (28.0% vs 27.7%) and non-pregnant (22.6% vs 20.0%) women, but the differences were not statistically significant (p > 0.05). Women in the South had the greatest prevalence (23.2%), followed by those in the North (20.9%), Center (20.6%), and Mexico City (16.4%). Non-pregnant indigenous women had a prevalence of 24.8%, while in-non-indigenous women the prevalence was 20.4%.
Anemia in women of childbearing age is a growing public health problem that justifies the implementation of interventions for its prevention and control. The English version of this paper is available too at: http://www.insp.mx/salud/index.html.
The objective of the study was to measure the prevalence of overweight and obesity in Mexican school-age children (5-11 years) in the National Nutrition Survey 1999 (NNS-1999).
Overweight and obesity (defined as an excess of adipose tissue in the body) were evaluated through the Body Mass Index (BMI) in 10,901 children, using the standard proposed by the International Obesity Task Force. Sociodemographic variables were obtained using a questionnaire administered to the children's mothers.
The national prevalence of overweight and obesity was reported to be 19.5%. The highest prevalence figures were found in Mexico City (26.6%) and the North region (25.6%). When adjusting by region, rural or urban area, sex, maternal schooling, socioeconomic status, indigenous ethnicity and age, the highest prevalences of overweight and obesity were found among girls. The risks of overweight and obesity were positively associated with maternal schooling, children's age and socioeconomic status.
Overweight and obesity are prevalent health problems in Mexican school-age children, particularly among girls, and positively associated with socioeconomic status, age, and maternal schooling. This is a major public health problem requiring preventive interventions to avoid future health consequences.

To determine the association between physical activity and overweight/obesity in Mexican adults.
Cross-sectional design. Adults 20 to 69 years of age were included in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006). The dependent variable was overweight/obesity and the independent variable was recalled physical activity. Analysis was by logistic regression, adjusting for sex, age, residence area, region, socioeconomic status, indigenous ethnicity, smoking, schooling, work activity, alcohol consumption and sitting time.
Data from 15 901 adults were analyzed. The prevalence of overweight/obesity had an inverse association with physical activity among men but not among women.
The practice of physical activity was negatively associated with the prevalence of overweight/obesity only in adult men. These results underscore the importance of promoting physical activity to prevent and control overweight/obesity.
