摘要身体活动（PA）的差异可能导致长期的体重控制。关于PA和青少年肥胖变化之间的反向关系的研究有限。本文探讨了PA对胡志明市（HCMC）青少年5年来体脂变化的影响。在2004年基线调查中接受过皮褶厚度测量的235名男孩和247名女孩被选为每年随访的对象。我们将PA估计为加速度计计数/h的平均数。计算三头肌斜率、肩胛下皮褶厚度和BMI，并将其分类为增加或稳定/降低。为了评估低水平活动（即低于平均计数的中位数）对脂肪增加（即斜率增加）的影响，使用泊松回归估计相对风险和95% CI。平均计数/h男生（7.8）显著高于女生（5.0）（P <0.001）。在控制基线能量摄入、基线肱三头肌厚度和基线年龄后，非活动组青少年肱三头肌皮褶厚度（TSF）平均增加0.51 mm，而活动组青少年减少0.12 mm。非活动组青少年肱三头肌皮褶厚度增加是活动组的1.39倍（95%CI 1.19，1.63）。基线时体脂较多者的风险比为1·62。一般来说，不运动的学生比运动量大的学生获得了更多的皮下脂肪，特别是在他们的TSF中。因此，胡志明市预防青少年肥胖的策略应考虑PA的重要作用，以有效地控制青少年肥胖问题。
Abstract Differences in physical activity (PA) might lead to long-term weight control. Studies on inverse relations between PA and changes in fatness among adolescents are limited. This paper examined the effect of PA on adolescents’ changing body fatness over 5 years in Ho Chi Minh City (HCMC). Two hundred thirty-five boys and 247 girls who have had skinfold thickness measurements in the baseline survey in 2004 were selected to follow yearly. We estimated PA as the average number of accelerometers’ counts/h. Slopes of triceps, sub-scapular skinfolds and BMI were calculated and classified as increasing or stable/decreasing. To assess the effects of the low level of activity (i.e. below the median of the average number of counts) on the fat gain (i.e. increasing slopes), relative risk and 95 % CI were estimated using Poisson regression. The average number of counts/h in boys (7·8) was significantly higher than that in girls (5·0) (P < 0·001). On average, active girls still gained 0·51 mm in triceps skinfold (TSF) over 5 years, while active boys lost 0·12 mm. After controlling for baseline energy intake, baseline triceps and baseline age, inactive adolescents were 1·39 times higher than active ones to increase the slope of triceps (95 % CI 1·19, 1·63). The risk ratio was 1·62 for those with more body fat at baseline. In general, inactive students gained substantially more subcutaneous fat, especially in their TSF, than more active ones. Thus, strategies to prevent adolescent obesity in HCMC should consider the important role of PA to control this problem in adolescents effectively.
