研究背景早产儿由于神经认知问题、肺功能下降和身体素质差，可能比足月儿缺乏体力活动。方法对2001年全国47,015例早产儿（其中早产儿2375例）和早产儿（早产儿37-38周）的运动参与情况进行分析。作为体育参与的指标，我们使用了对7岁和10岁时参加体育俱乐部以及15岁时参加课外学校体育活动的问题的回答。（25-31周）和中度至晚期早产在7岁、10岁和15岁时参加体育俱乐部的可能性低于足月出生的儿童（39-41周）。与足月出生的儿童相比，15岁时参加课外学校体育活动的校正风险比为0.86（95%置信区间：0.75-0.98）早产儿，0.92（0.88-0.97）对于中度至晚期早产儿，和1.00（0.98-1.02）结论我们的研究结果表明，早产与儿童和青少年时期较少参与有组织的体育活动有关影响调查2000年代出生的儿童中早产与体育活动之间关系的研究有限。这项研究表明，与足月出生相比，早产与儿童和青少年时期参与有组织体育活动的人数较少有关，特别是在男孩中，早产儿童参与有组织体育活动的人数随着妊娠期缩短而减少。在儿童时期，早产的男孩也比足月出生的男孩更不可能参加有组织的运动，这表明早产是一个连续体。这些发现为预测早产儿未来健康结果提供了重要的额外见解。
BackgroundChildren born preterm may be less physically active than children born term because of neurocognitive problems, reduced lung function, and poor physical fitness. We evaluated sports participation of children and adolescents who had been born preterm (<37 weeks) and early term (37–38 weeks) in 2001.MethodsData from a nationwide longitudinal survey (n= 47,015, including 2375 children born preterm) were analyzed. As indicators of sports participation, we used responses to questions about participation in sports clubs at 7 and 10 years old and in extracurricular school sports at 15 years old.ResultsChildren born very preterm (25–31 weeks) and moderately to late preterm (32–36 weeks) were less likely to participate in sports clubs at 7, 10, and 15 years old than children born full term (39–41 weeks). Compared with children born full term, the adjusted risk ratios for participation in extracurricular school sports at 15 years old were 0.86 (95% confidence interval: 0.75–0.98) for children born very preterm, 0.92 (0.88–0.97) for children born moderately to late preterm, and 1.00 (0.98–1.02) for children born early term.ConclusionsOur findings suggest that preterm birth is associated with less participation in organized sports during childhood and adolescence than full-term birth.ImpactResearch investigating associations between preterm birth and physical activity among children born in the 2000s is limited.This study shows that preterm birth was associated with less participation in organized sports during childhood and adolescence than full-term birth, especially in boys, and the participation in organized sports of children born preterm decreased as gestation shortened.During childhood, boys born early term were also less likely to participate in organized sports than boys born full term, suggesting a continuum with preterm births.These findings offer important additional insights into the limited evidence available for predicting future health outcomes for preterm infants.
