The basis of self-perceived physical competence is built in childhood and school personnel have an important role in this developmental process. We investigated the association between initial self-perceived physical competence and reported leisure-time physical activity (LTPA) longitudinally in 10-, 12-, and 15-year-old children.
This longitudinal follow-up study comprises pupils from an elementary school cohort (N = 1346) in the city of Turku, Finland (175,000 inhabitants). The self-perceived physical competence (fitness and appearance) and LTPA data were collected with questionnaires. The full longitudinal data were available from 571 pupils based on repeated studies at the ages of 10, 12, and 15 years in 2004, 2006, and 2010. We analyzed the association of self-perceived physical competence and LTPA using regression models.
Self-perceived physical competence was positively associated with LTPA at all ages (10 years p < .05, 12 years p < .0001, 15 years p < .0001). Increase in the self-perceived physical fitness scores was likely to associate with higher LTPA at each age point (10 years [odds ratio, OR] = 1.18, 95% confidence interval, CI: 1.09-1.27; 12 years [OR] = 1.27, 95% CI: 1.18-1.37; and 15 years [OR] = 1.28, 95% CI: 1.19-1.38).
Self-perceived physical competence is associated with LTPA in children and adolescents, and the association is strengthened with age.
自我认知的身体能力基础在童年时期奠定，学校工作人员在这一发展过程中发挥着重要作用。我们纵向调查了10岁、12岁和15岁儿童最初的自我认知身体能力与报告的休闲时间体育活动（LTPA）之间的关联。
这项纵向随访研究包括芬兰图尔库市（17.5万居民）一所小学队列中的学生（N = 1346）。通过问卷调查收集自我认知的身体能力（健康状况和外貌）和LTPA数据。基于2004年、2006年和2010年对571名学生在10岁、12岁和15岁时的重复研究，可获得完整的纵向数据。我们使用回归模型分析自我认知的身体能力与LTPA之间的关联。
在所有年龄段，自我认知的身体能力与LTPA均呈正相关（10岁p < .05，12岁p < .0001，15岁p < .0001）。在每个年龄点，自我认知的身体健康得分增加可能与更高的LTPA相关（10岁[优势比，OR] = 1.18，95%置信区间，CI：1.09 - 1.27；12岁[OR] = 1.27，95% CI：1.18 - 1.37；15岁[OR] = 1.28，95% CI：1.19 - 1.38）。
儿童和青少年的自我认知身体能力与LTPA相关，且这种关联随着年龄增长而增强。
