OLIVEIRA, Raphael Gonçalves de e GUEDES, Dartagnan Pinto. Determinants of lifestyle associated with metabolic syndrome in Brazilian adolescents. Nutr. Hosp. [online]. 2019, vol.36, n.4, pp.826-833. Epub 17-Fev-2020. ISSN 1699-5198. https://dx.doi.org/10.20960/nh.02459.
Background:
metabolic syndrome (MetS) has been diagnosed in adolescents. However, it remains uncertain which determinants of lifestyle are independently associated with its occurrence.
Objective:
to verify the association between lifestyle determinants (physical activity, sedentary behavior and food consumption) and MetS, by controlling demographic indicators and anthropometric nutritional status in a sample of adolescents from the southern region of Brazil.
Subjects and methods:
a school-based cross-sectional study involving 1,035 adolescents (565 girls and 470 boys) aged 12 to 20 years. Anthropometric measurements were performed and a questionnaire was applied with structured questions. MetS was identified according to criteria proposed by the International Diabetes Federation. The data were treated using bivariate analysis and hierarchical multiple regression.
Results:
the overall prevalence of MetS was equivalent to 4.5% (95% CI: 3.8 to 5.4). Multivariate analysis showed a significant association between MetS and age (OR = 1.34 [95% CI, 1.09 to 1.80]) and economic class (OR = 1.35 [95% CI: 1.08 to 1.86]). Among the determinants of lifestyle, high recreational screen time (OR = 1.32 [95% CI: 1.07 to 1.94]) and low fruit/vegetable intake (OR = 1.23 [95% CI: 1.01 to 1.87]) were independently associated with MetS. Likewise, obesity (OR = 1.62 [95% CI: 1.28 to 2.47]) was significantly associated with the outcome.
Conclusion:
in view of the significant association with MetS, intervention strategies should be designed to reduce recreational screen time and encourage fruit/vegetable consumption, especially among older adolescents, with a high economic class and obesity status.
