ABSTRACT

Information about nutritional status of teenagers in Mexico is rare. A few studies, mainly in women, use small sample size, therefore, extrapolations to other populations are inappropriate. There are not studies at all about body composition and prevalence of eating disorders. This study overcomes some of those problems. To determine the nutritional status (under nutrition, low weight, overweight and obesity) through the body mass index (BMI) and body composition. Also to determine the risk of potentially suffering eating disorders (anorexia, bulimia) through an eating Attitude test (EAT), in high and senior-high school teenagers in Queretaro, Mexico. A cross-sectional study was carried out in 1 232 teenagers 12 to 19 years old. Students included in the study were randomly chosen from two types of school (strata), public and private. Body composition by bioelectric impedance, weight and high were taken from all subjects. Alimentary misconduct was determined through a specific questionnaire. From the total of students, 460 were men and 772 women. Important prevalences were: undernutrition 13%, low weight 15%, overweight 13% and obesity 5%. Severe undernutrition was higher in men. Private schools showed higher levels of moderate undernutrition than public, but public had higher overweight and obesity. Undernutrition and low weight was more frequent in individuals 12 to 14 years old, obesity in those 18 to 19 years old. Corporal composition showed a high percentage of fat (72%), low percentage of muscle (67%), and low percentage of body water (72%). The percentage of individuals with high risk of alimentary misconduct was 0.3%, higher in public schools; 4.3% had moderate risk. The prevalence of undernutrition and low weight was 27%, for overweigth and obesity 18%. There is a high risk of suffering eating disorders, 0.3%. The prevalence of moderate risk of eating disorders was 4%.
