Individual-level measures of socioeconomic status (SES) may be difficult to assess for young women. The authors examined whether neighbourhood SES provides a useful measure in comparison with individual-level SES with respect to the burden of multiple chlamydia diagnoses.Methods In a study of young women with chlamydia (n=233; mean age =21 years), multiple infections were assessed with self-report and follow-up testing. General estimating equations and pseudo-R2 were used to assess the roles of individual-level SES (education and employment) and neighbourhood-level SES (percentage of people in census tract of residence below poverty) on multiple chlamydia diagnoses.Results Neither education nor employment was associated with multiple chlamydia diagnoses. Women living in high-poverty areas were significantly more likely than those living in low-poverty areas to have multiple chlamydia diagnoses (adjusted OR 3.46, 95% CI 1.18 to 10.15). This neighbourhood-level poverty measure improved model fit by 17%.Conclusions Neighborhood-level poverty may provide a better measure of SES than individual-level variables as a predictor of multiple chlamydia diagnoses in young women and can be useful when valid measures of individual-level SES are unavailable.
