Objectives. The age of adolescents at first sexual intercourse is an important risk factor for sexually transmitted diseases (STDs) and adolescent pregnancy. Black adolescents are at higher risk than white adolescents for first sexual intercourse at younger ages as well as STDs and pregnancy. Individual- and family-level factors do not fully explain this disparity. We examined whether five dimensions of black-white residential racial segregation can help explain the racial disparity in age at first sexual intercourse.

Methods. Using the National Longitudinal Survey of Youth 1997 and U.S. Census 2000 data, we performed multiple hierarchical discrete time-to-event analyses on a nationally representative cohort of adolescents followed since 1997. Although the cohort study is ongoing, we used data from 1997 through 2005.

Results. Concentration and unevenness significantly modified the association of race and age at first sexual intercourse. However, stratified results suggested differences in the effect of race on age at first sexual intercourse at each level of segregation across dimensions of segregation.

Conclusions. Residential racial segregation may modify the black-white disparity in risk of first sexual intercourse at younger ages, but these associations are complex. Future studies should be conducted to elucidate the causal mechanisms.

Background: Determining the underlying causes of racial disparities in sexually transmitted infections (STIs) is important. In the USA, rates of the most common STIs range from 5 to 20 times higher for African–Americans compared to Caucasians, and the health consequences of STIs can be serious. Residential racial segregation results in very different contexts for individuals and may be an important determinant of sexual risk. The purpose of this study was to examine how segregation and race interact to impact the age trajectory of sexual risk behaviours.

Methods: Using 11 years of data from the National Longitudinal Survey of Youth 1997 (1997–2007) and 2000 Census data, the authors performed three-level hierarchical linear regression to examine the associations between hypersegregation, race and a sexual risk behaviour index among black and white non-Hispanic adolescents as they transition to adulthood.

Results: Through most of the teenage years, African–Americans are at higher sexual risk than Caucasians. However, by age 19, Caucasians are at higher risk. Hypersegregation was not associated with increased sexual risk index score on average and did not impact the trajectory of the race–sexual risk association.

Conclusions: The authors did not find any evidence that hypersegregation was associated with the sex risk index or that it modified the race–sex risk association as individuals got older. Future studies should examine whether segregation is associated with other causes of STI/HIV acquisition risk, such as sexual network patterns.
