Abstract：
Purpose: Motor competence is negatively associated with body mass index (BMI) in young people. However, it is still unclear whether motor competence is linked to the risk of obesity in adolescents and longitudinal evidence is missing. The main purpose of this study was to assess the association between motor competence and risk of obesity across adolescence. Methods: A 2-year follow-up study was conducted with a total of 122 adolescents (59.8% girls) aged 12 to 13 years at baseline. Motor competence (KTK), weight status (BMI) and physical activity (questionnaire) were assessed at three time points. Generalized estimating equation and logistic regression models were conducted to examine the relationships between motor competence and weight status, adjusting for potential confounders (i.e. age, sex and physical activity). Results: Motor competence and BMI were inversely related over time. The chance to have overweight/obesity decreased by 6.5% and 8% with a 10-point increase in motor competence across time. In addition, adolescents had 6.4 to 8.2 greater chance to have low motor competence with a 1-point increase in BMI across time. Conclusion: Motor competence is inversely associated with the risk of overweight/obesity across adolescence. Therefore, the development of motor competence can be a protection factor against excessive weight gain. As such, we recommend the development of motor competence as a strategy to prevent pediatric obesity through diversified types of physical activities such as sports, active play and physical education classes.
摘要：
目的：年轻人的运动能力与体重指数（BMI）呈负相关。然而,目前尚不清楚运动能力是否与青少年肥胖风险相关,缺乏纵向证据.这项研究的主要目的是评估青春期运动能力与肥胖风险之间的关系。方法：对基线时年龄在12至13岁的122名青少年（59.8％的女孩）进行了为期2年的随访研究。运动能力（KTK），在三个时间点评估体重状态(BMI)和体力活动(问卷).进行了广义估计方程和逻辑回归模型，以检查运动能力与体重状态之间的关系，调整潜在的混杂因素(即年龄，性和身体活动)。结果：随着时间的推移，运动能力和BMI呈负相关。超重/肥胖的机会减少了6.5％和8％，随着时间的推移，运动能力增加了10个百分点。此外,随着BMI随时间增加1分,青少年运动能力低下的机会增加6.4~8.2.结论：运动能力与青春期超重/肥胖的风险呈负相关。因此,运动能力的发展可以成为防止体重过度增加的保护因素。因此，我们建议发展运动能力作为一种策略，通过多样化的体育活动，如运动，积极发挥和体育课。
