Timing of motor milestones achievement and development of overweight in childhood: a study within the Danish National Birth Cohort
Schmidt Morgen C, Andersen AMN, Due P et al
The objective was 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.
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.
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.
