| Popis: | Background A number of large studies have shown phenotypic differences between first-borns and later-borns among adult men. In this study, we aimed to assess whether birth order was associated with height and BMI in a large cohort of Swedish women. Methods Information was obtained from antenatal clinic records from the Swedish National Birth Register over 20 years (1991–2009). Maternal anthropometric data early in pregnancy (at approximately 10–12 weeks of gestation) were analysed on 13 406 pairs of sisters who were either first-born or second-born (n=26 812). Results Early in pregnancy, first-born women were of BMI that was 0.57 kg/m 2 (2.4%) greater than their second-born sisters (p 2 per year (p Conclusions Our study corroborates other large studies on men, and the steady reduction in family size may contribute to the observed increase in adult BMI worldwide. |
