背景：超重可能阻碍粗大运动里程碑的实现，延迟实现里程碑可能会增加日后超重的风险，原因涉及体力活动和瘦体重的形成。目的：调查5个月时出生体重和体重指数(BMI)的增加是否与坐起和行走能力的获得有关，以及这些里程碑的延迟实现是否与7岁时超重有关。方法：我们使用了丹麦国家出生队列中1998年至2003年出生的25148名儿童的数据。2003年至2010年进行了后续行动。平均随访年龄为7.04岁。结果：出生5个月时的出生体重和体重指数与较早获得坐起和行走能力的相关性较小(回归系数在-0.027个月[CI-0.042；-0.013]和-0.092个月[CI-0.118；-0.066]之间)。坐着和走路的月份的年龄与7岁时的超重无关(OR介于0.97[CI 0.95-1.00]和1.00[CI 0.96-1.04]之间)。坐着和走路的较晚成就预示着7岁时较低的体重指数(ln-bmi-z得分介于-0.023[CI-0.029；-0.017]和-0.005[CI-0.015；0.005]之间)。结论：所有观察到的相关性都可以忽略不计，我们得出结论，出生5个月时的出生体重或体重指数与运动里程碑似乎在很大程度上是相互独立的，运动里程碑的实现时间似乎与后来的超重或体重指数增加无关。
Background: Overweight may hinder achievement of gross motor milestones and delayed achievement of milestones may increase the risk of later overweight for reasons involving physical activity and the building of lean body mass.Objective: To investigate whether increased birth weight and body mass index (BMI) at 5 months is associated with the achievement of the ability to sit up and walk and whether delayed achievement of these milestones is associated with overweight at age 7 years.Methods: We used data from the Danish National Birth Cohort on 25 148 children born between 1998 and 2003. Follow-up took place from 2003 to 2010. Mean age at follow-up was 7.04 years. We used logistic and linear regression analyses.Results: Birth weight and BMI at 5 months were marginally associated with earlier achievement of the ability to sit up and walk (regression coefficients between -0.027 months; [CI -0.042; -0.013] and -0.092 months [CI -0.118; -0.066]). Age in months of sitting and walking were not associated with overweight at age 7 years (ORs between 0.97 [CI 0.95-1.00] and 1.00 [CI 0.96-1.04]). Later achievement of sitting and walking predicted lower BMI at age 7 years (ln-BMI -z-scores between -0.023 [CI -0.029; -0.017] and -0.005 [CI -0.015; 0.005)).Conclusions: All observed associations were of negligible magnitude and we conclude that birth weight or BMI at age 5 months and motor milestones appear largely independent of each other and that timing of achievement of motor milestones seems not to be associated with later overweight or increased BMI.
