Background

The purpose of this study was to describe associations between physical activity (PA), mental health and academic achievement in a Norwegian adolescent cohort.

Methods

In total, 1001 adolescents were invited to participate, of whom 599 (54.4% female, mean age ± SD 13.3 ± 0.3y) entered the study. PA was measured objectively using accelerometers, variables on mental health were assessed through an online questionnaire and academic achievement was assessed using grade point average (GPA) collected through school records. The associations between PA, mental health and academic achievement were modelled using multiple linear regression.

Results

PA was positively associated with mental wellbeing (p ≤ .05), self-perception of athletic competence (p ≤ .001) and self-perception of social acceptance (p ≤ .001). It was not associated with global self-esteem or mental health complaints. No significant association between PA and GPA was found. However, results showed a significant association between PA and grade in physical education among girls (p ≤ .001).

Conclusion

PA was associated with mental wellbeing and domain specific self-esteem although the causal significance of the association requires further investigation. The current study does not support associations between PA and mental health problems or PA and academic achievement. Further studies are necessary to investigate the longitudinal relationship between PA, variables of mental health and academic achievement amongst adolescents.

身体活动，心理健康和学习成绩：挪威青少年的横断面研究

背景

这项研究的目的是描述挪威青少年队列中的体育活动（PA），心理健康与学业成绩之间的关联。

方法

总共邀请了1001名青少年参加，其中599名（女性占54.4％，平均年龄±SD 13.3±0.3y）参加了研究。使用加速度计客观地评估PA，通过在线问卷调查评估心理健康变量，并使用通过学校记录收集的平均绩点（GPA）评估学业成绩。PA，心理健康和学业成绩之间的关联使用多元线性回归建模。

结果

PA与心理健康（p≤.05），运动能力的自我感知（p≤.001）和社会接受的自我感知（p≤.001）呈正相关。它与全球自尊或心理健康投诉无关。在PA和GPA之间未发现显着关联。但是，结果表明，女孩的体育课成绩与PA显着相关（p≤.001）。

结论

PA与心理健康和特定领域的自尊相关，尽管这种关联的因果关系有待进一步研究。当前的研究不支持PA与心理健康问题或PA与学术成就之间的关联。有必要进行进一步的研究以调查青少年中PA，心理健康变量和学习成绩之间的纵向关系。
