Abstract
Description
Background/Aim: Obesity in adolescents is increasing; as such, the aim of this study was
to determine the prevalence of obesity in Mexican adolescents and examine its possible association
with hours of sleep. Methods: A school-based cross-sectional study was carried out. This study
included 863 adolescents aged between 11 and 16 years. The prevalence of obesity was estimated
using the body mass index (BMI). The duration of sleep (and other information) was assessed
by a self-reported questionnaire. The Cochran–Mantel–Hansel test for categorical variables and a
general linear model for continuous variables were used to evaluate the interaction effect of BMI
and sex with respect to sleeping and assessed activity conditions. Results: It was found that 47.6%
of the adolescents were overweight/obese. Men were more frequently overweight/obese than
women (52.6% vs. 41.8%, p = 0.002). Moreover, overweight/obese adolescents were younger and
spent fewer daily hours watching television (p < 0.05). Men practiced sports more hours per week
than women (p = 0.04). However, women spent more daily time on the internet (p = 0.05), and
overweight/obese adolescent women slept fewer hours than overweight/obese men and adolescents
with normal weight (p = 0.008). Conclusions: The development of strategies for the prevention of
overweight/obesity and the improvement of sleep duration should include a gender perspective to
improve health habits in Mexican adolescents.
