We sought to investigate the longitudinal associations of moderate-to-vigorous physical activity (MVPA) and pubertal development with academic achievement in adolescents.
A total of 635 adolescents (283 boys, 352 girls) aged 11-13 years participated in the study. MVPA was assessed by the Health Behaviour in School-aged Children study questionnaire, and pubertal development was assessed by the Pubertal Development Scale at beginning of the 6th grade (baseline) and end of the 7th grade (follow-up). Grade point average (GPA) at the end of Grades 5 and 7 was computed from data acquired from the school registers. The data were analyzed using linear regression and analyses of covariance.
In boys, MVPA was positively associated with GPA at baseline after adjustment for age (β = 0.144, 95% confidence interval (CI): 0.028-0.260, p = 0.028). In girls, the Pubertal Development Scale was positively associated with GPA at baseline (β = 0.104, 95%CI: -0.004 to 0.211, p = 0.058) and follow-up (β = 0.104, 95%CI: -0.002 to 0.211, p = 0.055) after adjustment for age, and these associations strengthened after further adjustment for MVPA (p < 0.05). Adolescents who were inactive at baseline or at baseline and follow-up had lower GPA during follow-up than their continuously highly active peers (mean difference = -0.301, 95%CI: -0.543 to -0.058, p = 0.009) and all other adolescents (mean difference = -0.247, 95%CI: -0.475 to -0.019, p = 0.029). These differences were greater in girls than in boys.
Lower levels of MVPA were associated with lower GPA in boys at baseline. Girls who were continuously inactive had lower GPA over the follow-up period than those who were continuously active. Finally, earlier pubertal development was associated with better academic achievement in girls.
我们旨在探究青少年时期的中高强度体力活动（MVPA）和青春期发育与学业成绩之间的纵向关联。
共有 635 名 11-13 岁的青少年（男 283 人，女 352 人）参与了本研究。MVPA 通过《青少年健康行为调查》问卷进行评估，青春期发育通过《青春期发育量表》在六年级开始（基线）和七年级结束（随访）时进行评估。五年级和七年级结束时的平均绩点（GPA）是根据从学校登记处获得的数据计算得出的。数据使用线性回归和协方差分析进行分析。
在男孩中，MVPA 与基线时的 GPA 呈正相关，调整年龄后（β=0.144，95%置信区间（CI）：0.028-0.260，p=0.028）。在女孩中，青春期发育量表与基线时的 GPA 呈正相关（β=0.104，95%CI：-0.004 至 0.211，p=0.058）和随访时的 GPA 呈正相关（β=0.104，95%CI：-0.002 至 0.211，p=0.055），在调整 MVPA 后，这些关联得到了加强（p<0.05）。基线或基线和随访时不活跃的青少年在随访期间的 GPA 低于持续高度活跃的同龄人（平均差异=-0.301，95%CI：-0.543 至 -0.058，p=0.009）和所有其他青少年（平均差异=-0.247，95%CI：-0.475 至 -0.019，p=0.029）。这些差异在女孩中比男孩中更为明显。
较低水平的 MVPA 与男孩在基线时的 GPA 较低有关。持续不活跃的女孩在随访期间的 GPA 低于持续活跃的女孩。最后，青春期发育较早与女孩的学业成绩较好有关。
