Background The relationship between physical activity and health care costs among adolescents is not yet clear in the literature. Objective To analyze the relationship between physical activity and annual health care costs among adolescents. Methods The present sample was composed of 85 adolescents of both sexes with ages ranging from 11 to 18 years (mean age 15.6 ± 2.1). Health care costs were self-reported every month for 12 months, and information on health care values was verified with local pharmacies, private health care plans, and the National Health Service. The time spent in different physical activity intensities was objectively measured by accelerometers. Confounding variables were: sex, age, somatic maturation, body fatness, blood pressure, and components of dyslipidemia and insulin resistance. Multivariate models were generated using generalized linear models with gamma distribution and a log-link function. Results The overall annual health care cost was US$ 733.60/ R$ 2,342.38 (medication: US$ 400.46 / R$ 1,278.66; primary and secondary care: US$ 333.14 / R$ 1,063.70). The time spent in vigorous physical activity (minutes/day) was negatively related to health care costs (r = -0.342 [95% CI: -0.537,—0.139]; β = -0.06 cents (95% CI: -0.089, -0.031). Conclusion Vigorous physical activity seems to be associated with lower health care costs among adolescents.

However, it is still unclear whether the association between sports, blood pressure, and metabolic profile could be affected by sex, biological maturation, and trunk fatness. The aim of this study was to analyze the association between sports participation and the cluster of cardiovascular markers among adolescents of both sexes. Methods: A cross-sectional study involving 285 adolescents aged from 11 to 17 years of age (202 boys and 83 girls). Cardiovascular variables were composed of systolic blood pressure (SBP), diastolic blood pressure (DBP), resting heart rate (RHR), and carotid (CIMT) and femoral (FIMT) intima–media thickness, which were used to calculate the CardiovascularZ score. Sports participation was assessed through a face-to-face interview. Age of peak height velocity (APHV) was used as a covariate. Results: Among girls, the group engaged in sports presented lower values of RHR (sport: − 0.344 [95% CI − 0.650 to − 0.037] versus non-sport: 0.540 [95% CI 0.125 to 0.954]) and CardiovascularZ score (sport: − 0.585 [95% CI − 1.329 to 0.159] versus non-sport: 0.879 [95% CI − 0.127 to 1.884]), explaining 12.2% and 6.1% of all variance, respectively. Among boys, the group engaged in sports presented lower values of DBP (sport: − 0.158 [95% CI − 0.335 to 0.018] versus non-sport: 0.160 [95% CI − 0.091 to 0.412]) and FIMT (sport: − 0.128 [95% CI − 0.300 to − 0.044] versus non-sport: 0.211 [95% CI − 0.032 to 0.454]), explaining 2.2% and 2.6% of all variance, respectively. Conclusions for Practice: Adolescents engaged in sports presented healthier cardiovascular parameters, and sports participation seems to affect cardiovascular health differently in boys and girls.
