Psychosocial Factors and Preterm Birth Among African American and White Women in Central North Carolina

OBJECTIVES: We assessed associations between psychosocial factors and preterm birth, stratified by race in a prospective cohort study. METHODS: We surveyed 1898 women who used university and public health prenatal clinics regarding various psychosocial factors. RESULTS: African Americans were at higher risk of preterm birth if they used distancing from problems as a coping mechanism or reported racial discrimination. Whites were at higher risk if they had high counts of negative life events or were not living with a partner. The association of pregnancy-related anxiety with preterm birth weakened when medical comorbidities were taken into account. No association with preterm birth was found for depression, general social support, or church attendance. CONCLUSIONS: Some associations between psychosocial variables and preterm birth differed by race.
