目的：检查参与挪威母子队列研究（MoBa）的儿童从出生到7岁的身体尺寸跟踪，并探索与在生命的这一时期保持高身体尺寸相关的儿童和父母特征。设计：通过向母亲发送的问卷收集出生时以及1、3和7岁时的人体测量数据。设置：参与者是在1999- 2008年期间从挪威各地招募的。受试者：共有3771名儿童在出生时以及1岁、3岁和7岁时有完整的人体测量数据;样本包括2002年至2004年期间出生的儿童。Cohen的加权Kappa值表明，从出生到7岁，身体大小的跟踪为中等（0.36）至中等（0.43）。广义估计方程进一步表明，出生时体重指数最高三分位数的儿童在7岁时的BMI（kg/m2）比出生时体重指数其他三分位数的儿童高出近一个单位。父母BMI高（>= 25.0 kg/m2）增加了从出生到7岁具有稳定的高体型的几率;此外，女孩的几率明显高于男孩。结论：研究表明从出生到7岁的体型追踪是中等至中等的。从公共卫生的角度来看，早期预防儿童超重和肥胖似乎对父母BMI高的儿童尤为重要。
Objective: To examine tracking of body size among children participating in the Norwegian Mother and Child Cohort Study (MoBa) from birth to 7 years of age and additionally to explore child and parental characteristics associated with maintenance of a high body size in this period of life.Design: Anthropometric data at birth and at 1, 3 and 7 years of age were collected by questionnaires addressed to the mother.Setting: Participants were recruited from all over Norway during the period 1999-2008.Subjects: A total of 3771 children had complete anthropometric data at birth and at 1, 3 and 7 years of age; the sample includes children born between 2002 and 2004.Results: Cohen's weighted kappa pointed to fair (0.36) to moderate (0.43) tracking of body size from birth to 7 years of age. Generalized estimating equations further indicated that children in the highest tertile of ponderal index at birth had nearly one unit higher BMI (kg/m(2)) at the age of 7 years compared with children in other tertiles of ponderal index at birth. Having parents with high BMI (>= 25.0 kg/m(2)) increased the odds of having a stable high body size from birth to 7 years of age; moreover, girls had significantly higher odds compared with boys.Conclusions: The study indicates fair to moderate tracking of body size from birth to 7 years of age. From a public health perspective, early prevention of childhood overweight and obesity seems to be especially important among children of parents having a high BMI.
