Salud Pública de México , 2003,
Abstract: OBJECTIVE: 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). MATERIAL AND METHODS: 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. RESULTS: 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%. CONCLUSIONS: Anemia in women of childbearing age is a growing public health problem that justifies the implementation of interventions for its prevention and control.

Salud Pública de México , 2003,
Abstract: OBJECTIVE: 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). MATERIAL AND METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Clinical Medicine : Pediatrics , 2008,
Abstract: Background: Maternal nutrition and some variables are the main determining factors of birthweight and delayed intrauterine growth of children.Objective: To explore the association between the mothers’ biological and sociodemographic characteristics, and the anthropometry status in children under five years of age.Design: The population consisted of a sub-sample of 1,047 mother-and-child selected pairs from the probabilistic National Nutrition Survey, carried out in Mexico. Mother-and-child pairs included mothers aged 12 to 49 years, with children under five years of age. Data on sociodemographic characteristics, obstetric history, 24-hour recall dietary intake, and the women and children’s anthropometry were collected. The association between maternal characteristics and children’s anthropometry status was assessed using multiple logistic regression models.Result: Nearly 16.7% of the children <5y of age were stunted (13.5% ≤2y and 18.8% >2y). The height/age of the children was severely affected by maternal height and birth order. In addition, the interaction between socioeconomic level and maternal schooling had a marginal effect (p = 0.09) in the ≤2y group. On the other hand, whether the family received social services and the interaction between maternal height and a dichotomy urbanism variable were significant ( p = 0.05) and (p <0.01) respectively in >2y group.Conclusion: Some biological and socioeconomic characteristics among mothers have a negative effect on their children’s attained size, especially in the period between 2 and 5 years of age.
