Disparities in the usage of maternity leave according to occupation, race/ethnicity, and education

Background Unlike almost all other countries, the United States does not mandate paid maternity leave for mothers. Lack of access to maternity leave may be a risk factor for adverse maternal and child health outcomes. This study sought to assess disparities in the usage of maternity leave according to maternal occupation, race/ethnicity, and education, and to explore the relationships between these factors. Methods We used data from the Pregnancy Risk Assessment Monitoring System from the years 2016 and 2017. We calculated the prevalence of usage of maternity leave and paid maternity leave according to the mother's age, race/ethnicity, education, state, and occupation. We constructed regression models to explore the bivariate and mutually adjusted associations between these factors and usage of maternal leave. Results Usage of maternity leave and paid maternity leave were estimated at 89.3% and 49.0%, respectively. Usage of paid maternity leave was lower in younger mothers, in Black and Hispanic mothers, and in mothers with fewer years of education. Workers in several occupations, including building and grounds cleaning and maintenance, personal care, and food preparation and serving, used maternity leave at rates significantly lower than the average of all workers. Adjustment for education and occupation reduced, but did not obviate, racial/ethnic differentials in usage of paid maternity leave. Conclusions There are substantial differentials in usage of maternity leave. Further research could examine whether these differences contribute to disparities in maternal and child health outcomes.
