ABSTRACT
Abstract The association of moderate to vigorous physical activity and sedentary behavior performed in the school context with cardiovascular risk factors is unclear. Thus, the purpose of this study was to evaluate whether MVPA and SB during school time are associated with single and clustered cardiovascular risk factors in 10- to 16-year-old school students. This study used the baseline data from a non-randomized controlled clinical trial ("MEXA-SE") conducted on 6th to 9th-grade students from schools in Florianopolis, Brazil. Skinfolds, resting blood pressure, 20-m shuttle-run test, fasting glucose, triglycerides, total cholesterol, high-density lipoprotein cholesterol, and white blood cell counts were obtained. MVPA and SB were objectively measured with accelerometers. A minimum of 180 minutes was considered valid school-time for analysis. Multiple linear regression adjusted for age, sex and habitual physical activity was used. School-time MVPA was positively associated with the peak VO2 (β = 0.17 ml.kg.min-1), and inversely associated with sum of four skinfolds (β = -0.96 mm), diastolic blood pressure (β = -0.36 mmHg), systolic blood pressure (β = -0.301 mmHg); triglycerides (β = -1.49 mg.dL-1), and clustered cardiovascular risk factors (β = -0.123). School-time SB was positively associated with clustered cardiovascular risk factors (β = 0.033). In conclusion, independently of habitual physical activity level, school-time MVPA and a lower time in SB were associated to single and clustered cardiovascular risk factors. Thus, the promotion of strategies aimed increase MVPA and reduce SB at school may prevent the onset and early accumulation of cardiovascular risk factors in adolescence.
RESUMO
Resumo A associação da atividade física moderada a vigorosa (AFMV) e do comportamento sedentário (CS) realizados no contexto escolar com fatores de risco cardiovascular é inconclusiva. Assim, o objetivo do presente estudo foi avaliar se a AFMV e o CS realizados durante o período escolar estão associados a fatores de risco cardiovasculares em escolares de 10 a 16 anos. Utilizou-se os dados da linha de base de um estudo clínico controlado não randomizado ("MEXA-SE") realizado com alunos do 6º ao 9º ano de escolas de Florianópolis, Brasil. Dobras cutâneas, pressão arterial, teste de vaivém de 20 metros, glicemia de jejum, triglicerídeos, colesterol total, lipoproteína de alta densidade e contagem de glóbulos brancos foram mensurados. A AFMV e CS foram medidos objetivamente com acelerômetros. Foi preconizado um período mínimo de 180 minutos de uso para considerar o tempo válido e realizou-se regressão linear múltipla ajustada para idade, sexo e atividade física habitual. A AFMV foi associada positivamente com VO2 pico (β=0,17 ml.kg.min-1) e inversamente associada à soma das quatro dobras cutâneas (β=-0,96 mm), pressão arterial diastólica (β=0,36 mmHg), pressão arterial sistólica (β=-0,301 mmHg); triglicerídeos (β=-1,49 mg.dL-1) e fatores de risco cardiovasculares agrupados (β=-0,123). Houve também associação positiva do CS com fatores de risco cardiovascular agrupados (β=0,033). Conclui-se que a AFMV e o CS foram associados a fatores de risco cardiovasculares. Assim, a promoção de estratégias que visem aumentar a AFMV e reduzir o SB no contexto escolar pode impedir o aparecimento e o acúmulo precoce de fatores de risco cardiovasculares na adolescência.
