Low Job Control and Racial Disparities in Breastfeeding.

Abstract

Low job control may predict shorter breastfeeding (BF) among working mothers and may contribute to racial disparities in BF. We used demographic, employment, and health data for n = 631 observations from the Panel Study of Income Dynamics. Job control scores came from a job-exposure matrix.Using path analysis, we assessed whether job control predicted BF and mediated Black-White BF differences. We controlled for education, working hours, marital status, and low birthweight. Lower job control predicted decreased odds of BF for at least 6 months (odds ratio, 0.61; 95% confidence interval, 0.31-0.90; reference, no BF). Low job control explained 31% of the Black-White difference for both shorter-term and longer-term BF. Low job contributes to shorter BF and to BF disparities by race. Intervening to enhance job control could improve BF.
