Abstract
New York City birth certificates for singletons born from September 1-December 31, 1981 (N = 36,056) were analyzed using multivariate regression techniques. The effects of maternal age and parity on birthweight were assessed. There was a significant progression of birthweight with advancing age. Birthweight similarly increased from parity 1 to parity 3, but dropped markedly in the higher parity groups. On stratification by gestational age, we found that age and parity influence birthweight by affecting fetal growth rather than the length of pregnancy.Keywords: Age Factors; Americas; Biology; Birth Weight; Body Weight; Comparative Studies; Data Analysis; Demographic Factors; Developed Countries; Developing Countries; Fertility; Fertility Measurements; Fetus; Gestational Age; Health; Maternal Age; Maternal Health; Maternal Nutrition; New York; North America; Northern America; Nutrition; Parental Age; Parity; Physiology; Population; Population Characteristics; Population Dynamics; Pregnancy; Reproduction; Research Methodology; Research Report; Studies; United States
