To investigate whether level of prematurity (very, moderate, late preterm, vs full term) is associated with physical activity from childhood to adolescence and to identify factors in childhood that predict moderate-vigorous physical activity in early adolescence.
Parents reported on physical activity at the age 5, 7, and 11 years (n = 12 222-14 639) and adolescents self-reported on moderate-vigorous physical activity at 14 years (n = 10 974). At age 14 years, a subgroup was also assessed by wrist accelerometer (n = 4046).
Prematurity was associated with a small or no difference in physical activity at each time point. At age 14 years, moderate-vigorous physical activity in self-report and accelerometer was higher in male adolescents, those of white ethnicity, or higher parental education, having been taken to live sport events at age 5 or 7 years or having taken part in organized physical activity at 5 or 7 years.
In this representative national cohort study in the United Kingdom, preterm birth was not found to be associated with physical activity between 5 and 14 years. Organized physical activity and watching sport events early in life may increase moderate to vigorous physical activity in adolescents.
研究早产程度（极早产、中度早产、晚期早产、足月产）是否与儿童期到青春期的身体活动有关，并确定儿童时期的哪些因素可预测青少年早期的中高强度身体活动。
家长在儿童 5 岁、7 岁和 11 岁时报告身体活动情况（n=12222-14639），青少年在 14 岁时自我报告中高强度身体活动情况（n=10974）。在 14 岁时，还通过手腕加速度计对一小部分人（n=4046）进行了评估。
早产与每个时间点的身体活动量的小或无差异有关。在 14 岁时，自我报告和加速度计测量的中高强度身体活动在男性青少年、白种人青少年或父母受教育程度较高的青少年中更高，在 5 岁或 7 岁时曾带他们观看过体育赛事或在 5 岁或 7 岁时参加过有组织的体育活动的青少年中更高。
在英国这项具有代表性的全国队列研究中，早产与 5 岁至 14 岁之间的身体活动之间似乎没有关联。生命早期有组织的体育活动和观看体育赛事可能会增加青少年的中高强度身体活动量。
