Abstract
We examined the association between racial/ethnic minority segregation and low birth weight (LBW) in Chicago and Toronto communities. While previous work has documented the importance of contextual effects on LBW, these studies have usually been conducted within a single city. We used Pearson correlation coefficients and OLS regression models to examine potential variability in the association between racial/ethnic minority segregation and LBW in Chicago (N = 77 communities) and Toronto (N = 140 communities). Results indicate that racial/ethnic minority segregation, unemployment, and low educational attainment are not associated with LBW in Toronto, while these indicators have strong and significant associations with LBW in Chicago. In a combined model with data from both cities, a 10% increase in minority composition is associated with a 0.5% increase in LBW, controlling for the effects of unemployment and low educational attainment. Stratified models show that this effect is only significant in Chicago, and subsequent models revealed opposite effects for percentage non-Hispanic Black and percentage Hispanic. Future research should consider additional cities for comparative analysis. Such work could test the notion that Chicago and Toronto represent opposite sides of a spectrum, reflecting variability in how social determinants map on to public health outcomes. Future research should also examine the significant heterogeneity observed in highly segregated communities, particularly in Chicago.
