Predicting physical activity in a national cohort of children born extremely preterm.
To compare physical activity among school-aged children born extremely preterm or with extremely low birthweight (EP/ELBW) to term-born children, and to identify early predictors for physical inactivity in the EP/ELBW-children.
A national cohort born during 1999-2000 at gestational age < 28 weeks or birthweight <1000 g and term-born controls were assessed. EP/ELBW-children without neurodevelopmental disabilities were labeled "healthy". At five years, we examined the EP/ELBW-children's motor, mental and intellectual functioning using the Movement Assessment Battery for Children (MABC), The Strength and Difficulties Questionnaire (SDQ) and The Wechsler Preschool and Primary Scale of Intelligence-revised. At 11 years, the parents reported their children's physical activity (PA) in questionnaires.
Information was obtained from 231/372 EP/ELBW and 57/61 term-born children. At 11 years, EP/ELBW-children had fewer exercise events per week, were less engaged in team sports, had lower endurance, lower sports proficiency, and were less vigorous during PA than term-born children (p < 0.05). Low sports proficiency in the healthy EP/ELBW-children at 11 years was predicted (odds ratio; 95% confidence interval) by abnormal MABC-score (3.0; 1.0 to 8.7), and abnormal SDQ-score (4.0; 1.6 to 10.0) at 5 years. Lower endurance at PA was predicted by abnormal MABC-score (2.6; 1.0 to 6.6), abnormal SDQ-score (3.0; 1.4 to 6.5), and borderline intellectual functioning (4.2; 1.8 to 10.1).
Eleven-year-old EP/ELBW-children were less physically active than term-born. In healthy EP/ELBW-children, impaired motor coordination, borderline intellectual functioning and behavioral problems at 5 years of age predicted unfavorable PA habits at 11 years.
预测一个全国性极低出生体重早产儿队列的体力活动。
比较早产儿或极低出生体重儿（EP/ELBW）与足月出生儿童的体力活动，并确定 EP/ELBW 儿童体力活动不足的早期预测因素。
对 1999-2000 年在妊娠 28 周以下或出生体重<1000g 的全国性队列中的 EP/ELBW 儿和足月出生的对照组进行评估。无神经发育障碍的 EP/ELBW 儿童被标记为“健康”。在 5 岁时，我们使用运动评估电池对 EP/ELBW 儿童的运动、精神和智力功能进行了检查（儿童运动评估电池）（MABC），《力量与困难问卷》（SDQ）和《韦氏学前和小学智力量表修订版》。在 11 岁时，父母通过问卷报告了他们孩子的体力活动（PA）。
共获得 231/372 名 EP/ELBW 和 57/61 名足月出生儿童的信息。在 11 岁时，EP/ELBW 儿童每周的运动事件较少，参与团队运动较少，耐力较低，运动技能较低，运动时的活力较低比足月出生的儿童（p<0.05）。11 岁时，健康的 EP/ELBW 儿童运动技能较差，预测因素为 5 岁时 MABC 评分异常（3.0；1.0 至 8.7）和 SDQ 评分异常（4.0；1.6 至 10.0）。PA 耐力较低的预测因素为 MABC 评分异常（2.6；1.0 至 6.6），SDQ 评分异常（3.0；1.4 至 6.5）和边缘智力功能（4.2；1.8 至 10.1）。
11 岁的 EP/ELBW 儿童的体力活动水平低于足月出生的儿童。在健康的 EP/ELBW 儿童中，5 岁时运动协调能力受损、边缘智力功能和行为问题预测 11 岁时不良的 PA 习惯。
