title: The effect of socioeconomic indicators and macronutrient intake rate on body composition in adolescents 12 to 16 years old in Merida, Yucatan.
abstract: Intake pattern of macronutrients (protein, lipid, carbohydrate) and socioeconomic status (SES) are major causes of high child and adolescent overweight and obesity prevalences in Mexico. An evaluation was done of the relationship between body mass index (BMI)-based nutritional status and body composition (BC), macronutrient intake rates (MIR) and SES indicators in 127 boys and 156 girls aged 12 to 16 years attending schools in Merida, Mexico. Anthropometric variables included height, weight, and BMI. The BC (body fat mass, fat-free mass, dry lean mass) was estimated by bioelectrical impedance (Bodystat 1500 MDD). The MIR were estimated following FAO/WHO/UNO standard (1985). Proxy socioeconomic indicators included parents' age (as a maturity indicator) and education, fathers' occupation, school type and monthly household food expenditure per capita. Excess weight (overweight + obesity) assessed by BMI, was higher in boys (40.16 %) than in girls (33.97 %). Boys had higher BMI, less fat mass and higher fat-free mass than girls. The MIR did not vary significantly in response to age, sex, BC or SES. Participants with higher SES were taller and heavier, had higher fat-free mass and lower fat mass. In the studied adolescents, anthropometric and BC values, and overweight and obesity rates were more associated with SES than MIR.
