Night Shift Work and Fecundability in Late Reproductive-Aged African American Women.

ABSTRACT: Background: We estimated the association between night shift work and fecundability among African American women. Methods: Black Women's Health Study participants (n = 560) aged 30-45 years reported their history of night shift work in 2005. Time to pregnancy for all pregnancies resulting in a livebirth was reported in 2011. We estimated the fecundability ratio (FR) and 95% confidence interval (CI) using proportional probabilities regression, accounting for multiple observations of individual women using generalized estimating equations. Results: We observed 4,417 months of pregnancy attempt time resulting in 390 births. After adjustment for covariates, women who reported ever working night shifts had 20% lower fecundability compared with th
