摘要

The purpose of this study was to evaluate the habits of photoprotection, sun exposure, and vitamin D in active and sedentary eutrophic adolescents. A total of 33 subjects (60.6% boys) between 10 and 17 yrs of age (mean ± SD, 13.8 ± 1.8 yrs) were divided into two groups according to their physical activity history (Active Group, n=19, ≥300 min?wk~(-1) and Sedentary Group, n=14, <150 min?wk~(-1) ). The vitamin D concentrations were measured and data on photoprotection and sun exposure were obtained. Statistical significance was set at P<0.05. In the total sample, 38.2% of the adolescents presented vitamin D sufficiency with no difference between the Active Group (50%) and the Sedentary Group (21%, P=0.09). The Active Group had higher concentrations of vitamin D (P=0.006) and a longer time of sun exposure during the week compared to the Sedentary Group (P<0.0001). However, only one-third of the adolescents used sunscreen when practicing outdoor sports. Regarding photoprotection, 61.8% used sunscreen of which 58.8% used it only in the summer and 44.1% only once a day. Active adolescents have higher concentrations of vitamin D and are exposed more to the sun, but the vitamin D sufficiency ratio was low and similar to the sedentary adolescents. Therefore, there are risks and benefits of sun exposure, and there is the need to consider the use of photoprotection during outdoor activities.
