背景资料：遗传和环境的影响已被证明有助于身体活动和整体学业成绩之间的关联。作者研究了在青春期早期，闲暇时间体育活动（LTPA）是否在拼写、写作、阅读、阅读理解和数学之间存在遗传和环境差异。此外，他们调查了是否与体力活动行为的遗传多态性影响这些学术skills.Methods：参与者是12岁的芬兰双胞胎（n = 4356-4370双胞胎/学术技能，49%的女孩）。学术技能由教师进行评估，LTPA是自我报告的。体力活动行为的多基因评分来自英国生物银行。结果：LTPA与学业技能之间的相关显著，但相关性较弱（r= 0.05 - 0.08）。LTPA与数学的相关性最高。LTPA和作文写作之间存在显著的遗传相关性（rA= .14）。关于身体活动的多基因分数，发现与阅读理解、拼写和论文写作的相关性最高，但这些结果仅接近统计学显著性（P值= 0.09 - 0.15）。结论：作者的结果表明，阅读和写作是最有可能与LTPA共享共同遗传背景的学术技能。
Background: Both genetic and environmental influences have been shown to contribute to the association between physical activity and overall academic performance. The authors examined whether leisure-time physical activity (LTPA) shares genetic and environmental variances between spelling, essay writing, reading aloud, reading comprehension, and mathematics in early adolescence. Moreover, they investigated whether genetic polymorphisms associated with physical activity behavior affect these academic skills.Methods: Participants were 12-year-old Finnish twins (n = 4356–4370 twins/academic skill, 49% girls). Academic skills were assessed by teachers, and LTPA was self-reported. Polygenic scores for physical activity behavior were constructed from the UK Biobank. Quantitative genetic modeling and linear regression models were used to analyze the data.Results: The trait correlations between LTPA and academic skills were significant but weak (r= .05–.08). The highest trait correlation was found between LTPA and mathematics. A significant genetic correlation was revealed between LTPA and essay writing (rA= .14). Regarding polygenic scores of physical activity, the highest correlations were found with reading comprehension, spelling, and essay writing, but these results only approached statistical significance (Pvalues = .09–.15).Conclusions: The authors’ results suggest that reading and writing are the academic skills that most likely share a common genetic background with LTPA.
