Impact/Purpose:
Explore association between reported income incongruity and PTB.
Description:
Previous research with vital records finds income incongruity associated with adverse birth outcomes. We examined the effects of negative income incongruity (reporting lower household income than the census tract median household income) on preterm birth (PTB <37 weeks completed gestation) using self-reported income for white (n=424) and black (n=566) non-Hispanic women living in Wake County NC tracts (1995-2005). Geocoded Pregnancy, Infection and Nutrition (PIN) cohort (n=1056) and U.S. census (2000) were analyzed in race-stratified logistic regression models. Income was collected during 2nd trimester telephone interview; gestational age was calculated from early ultrasound and reported last menstrual period. Blacks were less likely than whites to live in incongruous tracts (Odds Ratio [OR]=0.6; 95% Confidence Interval [CI]: 0.4, 0.8). White women of low education (
