Abstract
To estimate the association between multiple domains of physical activity and risk of smallforgestationalage SGA birth We utilized data from 1040 participants in the Latina Gestational Diabetes Mellitus Study a prospective cohort of predominantly Puerto Rican prenatal care patients in Massachusetts Physical activity was assessed by bilingual interviewers using a modified version of the Kaiser physical activity survey in early mean = 15 weeks and mid pregnancy mean = 28 weeks Physical activity ie sports/exercise household occupational and active living in pre early and mid pregnancy was categorized in quartiles SGA was classified as 10th percentile of birth weight for gestational age Pre and earlypregnancy physical activity were not associated with SGA In multivariable analyses women with high total activity in midpregnancy had a decreased risk of SGA risk ratio RR = 042 95 confidence interval CI 021–082 p trend = 0003 as compared to those with low total activity Findings were similar for high household activity RR = 069 95 CI = 034–140 p trend = 026 active living RR = 063 95 CI = 035–113 p trend = 004 and occupational activity RR = 079 95 CI = 047–134 p trend = 026 High levels of sports/exercise were associated with an increased SGA risk without a significant dose–response association RR = 214 95 CI 104–439 p trend = 033 Results extend prior studies of physical activity and SGA to the Hispanic population
