Detailed Description

The objective of the study is to examine whether duration of breastfeeding, timing of introduction of complementary food and protein intake at 18 months are associated with BMI and overweight at ages 7 and 11 years, independent of BMI during infancy. Children participating in the Danish National Birth Cohort were followed-up at ages 7 and 11years. Information on infant feeding, protein intake at 18 months, Ponderal Index at birth, child BMI (5 months, 12 months, 7 and 11 years) and several parental factors was available. Path analysis was used to assess the direct and indirect effects of infant feeding on BMI z-scores at ages 7 (n= 36,481) and 11y (n=22,047). Logistic regression analyses were used to examine associations with overweight.

Interventions

  • Other: Danish National Birth Cohort
    • DNBC is a nationwide cohort study of pregnant women and their offspring. The women were enrolled early during pregnancy between 1996 and 2002. They provided information on exposures during and after pregnancy by means of four computer-assisted telephone interviews in gestational weeks 12 and 30 and post-partum when the child was 6 and 18 months old.

Clinical Trial Outcome Measures

Primary Measures
