Neighborhood‐level racialized socioeconomic deprivation and contraceptive use in the United States, 2011–2019

Abstract

AbstractIntroductionThe social and structural environments where people live are understudied in contraceptive research. We assessed if neighborhood measures of racialized socioeconomic deprivation are associated with contraceptive use in the United States.MethodsWe used restricted geographic data from four waves of the National Survey of Family Growth (2011–2019) limited to non‐pregnant women ages 15–44 who had sex in the last 12 months. We characterized respondent neighborhoods (census tracts) with the Index of Concentration at the Extremes (ICE), a measure of spatial social polarization, into areas of concentrated privilege (predominantly white residents living on high incomes) and deprivation (predominantly people of color living on low incomes). We used multivariable binary and multinomial logistic regression with year fixed effects to estimate adjusted associations between ICE tertile and contraceptive use and method type. We also assessed for an interactive effect of ICE and health insurance type.ResultsOf the 14,396 respondents, 88.4% in neighborhoods of concentrated deprivation used any contraception, compared to 92.7% in the most privileged neighborhoods. In adjusted models, the predicted probability of using any contraception in neighborhoods of concentrated deprivation was 2.8 percentage points lower than in neighborhoods of concentrated privilege, 5.0 percentage points higher for barrier/coital dependent methods, and 4.3 percentage points lower for short‐acting methods. Those with Medicaid were less likely to use any contraception than those with private insurance irrespective of neighborhood classification.ConclusionsThis study highlights the salience of structural factors for contraceptive use and the need for continued examination of structural oppressions to inform health policy.
