    Abstract

    Background Although the benefits of physical activity (PA) at an early age are well established, there is no robust evidence
    of the role of PA as well as its intensities in attenuating the association between weight status and metabolic risk among
    adolescents. In this investigation, we analyzed the association between weight status, intensities of PA, and metabolic risk
    among adolescents.
    Methods Data from six cross-sectional studies in the International Children’s Accelerometry Database were used (N = 5216
    adolescents; boys 14.6 ± 2.1 years and girls 14.7 ± 2.0 years). Weight status was assessed and classified according to body
    mass index. Fasting glucose, triglycerides, inverse high-density lipoprotein cholesterol, and blood pressure composed the
    metabolic risk indicator (z-score). PA was measured by accelerometers. The estimated age of peak height velocity was used
    as a covariate for somatic maturation.
    Results We observed that increase in weight status showed a strong positive relationship with metabolic risk. However,
    adolescents with overweight or obesity in the highest tertile of PA (moderate-to-vigorous and vigorous intensity) showed a
    similar metabolic risk score as the normal weight groups. Moderate intensity PA seemed related to metabolic risk even
    within some categories of vigorous PA.
    Conclusions We conclude that PA attenuates the metabolic risk of adolescents with overweight or obesity. Although this
    attenuation is largely explained by vigorous PA, moderate intensity seems also important for better metabolic profile.
