Summary
Birth order influences infant birth weight, with later-born children being heavier. This association persists even for the tenth delivery in grand grand multiparous women.
Area of Science:
- Reproductive Medicine
- Maternal-Fetal Medicine
- Human Development
Background:
- Grand grand multiparity, defined as at least ten deliveries, presents unique considerations in obstetrics.
- Understanding factors influencing birth weight is crucial for neonatal health outcomes.
Purpose of the Study:
- To investigate the relationship between birth order and birth weight in women with at least ten deliveries.
- To determine if birth order remains a significant factor in birth weight among grand grand multiparous women.
Main Methods:
- A longitudinal study of 96 grand grand multiparous women (1098 deliveries) was conducted.
- Cross-sectional reference populations from 1966 and 1985-1986 were utilized.
- Birth weight was analyzed across four birth order groups: first, second-to-fifth, sixth-to-ninth, and tenth-to-twelfth born.
Main Results:
- Birth weight demonstrated a positive association with birth order across all study populations.
- This trend persisted after adjusting for gestational age, newborn sex, maternal diabetes, and BMI.
- Infants in the tenth to twelfth birth order group were significantly heavier than those in the sixth to ninth group.
Conclusions:
- Birth order is an independent determinant of birth weight, extending up to the tenth delivery.
- The findings highlight the continued influence of birth order on fetal growth in high-parity pregnancies.
