    ObjectivesTo investigate the early determinants of overweight and obesity status at age two years.MethodsA total of 1098 healthy neonates (563 boys and 535 girls) were involved in this community-based prospective study in China. Data on body weight and length were collected at birth, the 3(rd) and 24(th) month. A self-administered questionnaire was used to collect data on social demography and feeding patterns of children, etc. Three multivariable logistic regression models were employed to make various comparisons of weight status, i.e., model 1 (obesity vs. non-obesity), model 2 (combined overweight and obesity vs. normal weight, and model 3 (obesity, overweight and normal weight).ResultsPrevalences of overweight/obesity (95(th) >BMI ≥85(th) p and BMI ≥95(th) p, referring to WHO BMI standards) at 2 years of age are 15.8%/11.2% for boys and 12.9%/9.0% for girls, respectively. Being born with macrosomia (OR: 1.80-1.88), relatively greater BMI increment in the first 3 months (OR: 1.15-1.16) and bottle emptying by encouragement at age two (OR: 1.30-1.57) were found in all three models to be significant risk factors for higher BMI status at 2 years. Pre-pregnancy maternal BMI (OR: 1.09-1.12), paternal BMI (OR: 1.06), and mixed breastfeeding (OR: 1.54-1.57) or formula feeding (OR: 1.90-1.93) in the first month were identified as significant in models 2 and 3. Child-initiated bottle emptying at age two was observed to increase the risk of obesity by 1.31 times but only in model 1.ConclusionFetal and early postnatal growth and feeding pattern appear to have significant impacts on early childhood overweight and obesity status independent of parental BMI. Policy-based and multidisciplinary approaches to promote breastfeeding and enhancement of feeding skills of care takers may be promising intervention strategies.
