The impact of early growth patterns and XXXX feeding on body composition at 3 years of age.

@entity1 @entity1017 @entity28
UNASSIGNED: Early excessive @entity1017 is positively associated with @entity28 , and yet the effect of @entity1017 during specific periods and the impact of @entity1 feeding practices are debated. The objective of the present study was to examine the impact of @entity1017 in periods of early childhood on body composition at 3 years, and whether @entity1 feeding modified the relationship between early growth and body composition at 3 years. We studied 233 @entity1 from the prospective cohort study, SKOT (in Danish: Sm  b  rns Kost og Trivsel). Birth weight z-scores (BWZ) and change in weight-for-age z-scores (WAZ) from 0 to 5, 5 to 9, 9 to 18 and 18 to 36 months were analysed for relations with body composition (anthropometry and bioelectrical impedance) at 3 years by multivariate regression analysis. BWZ and change in WAZ from 0 to 5 months were positively associated with BMI, fat mass index (FMI) and fat-free mass index (FFMI) at 3 years. Full breastfeeding for 6 months (compared to less than 1 month) eliminated the effect of early growth (P=  0  01). Full breastfeeding for 6 months (compared to less than 1 month) also eliminated the positive relation between BWZ and FMI (P=  0  009). No effect modification of @entity1 feeding was found for FFMI. In conclusion, high birth weight and rapid growth from 0 to 5 months were associated with increased FMI and FFMI at 3 years. Longer duration of full breastfeeding reduced the effect of birth weight and early @entity1017 on fat mass.
