Abstract
Background/Aims: It was the aim of this study to evaluate the relationships between sweetened beverage (SB) consumption and the following indicators of overweight/fatness among Mexican adolescents: body mass index, body composition and body fat distribution. Methods: We performed a cross-sectional analysis of data from adolescents participating in the baseline assessment of the Health Workers Cohort Study. Information on sociodemographic conditions, sexual maturation, dietary patterns and physical activity was collected via self-administered questionnaires. SB consumption was evaluated through a validated semiquantitative food frequency questionnaire. Anthropometric measures were assessed with standardized procedures. The associations of interest were evaluated by means of multivariate regression and logistic regression models. Results: A total of 1,055 adolescents, 10–19 years old (mean age 14.5 ± 2.5 years), were evaluated. The overweight/obesity prevalence was 31.6% among girls and 31.9% among boys. We found that for each additional SB serving consumed daily, the subject’s body mass index increased by on average 0.33 (p < 0.001). Subjects consuming 3 daily servings of SB face a 2.1 times greater risk of proportionally excess body fat than those who consume less than 1 SB a day. Conclusions: Our data support the hypothesis that the consumption of SB increases the risk of overweight and/or obesity and encourages excess body fat and central obesity in Mexican adolescents.
