We used Poisson regression models to estimate the relationship between PPNM and incident concurrency among participants participating in a cohort study, interviewed at 4-month periods during 1 year. Concurrency was defined as an overlap in reported sexual partnership dates; PPNM was defined as believing a partner was also having sex with someone else. At each interview baseline, 4-month, 8-month and month , 4-month concurrency prevalence was, respectively, Four-month concurrency incidence at 4, 8 and 12 months was 8.
Recent PPNM was associated with incident concurrency. Among young adults, onset of concurrency may be stimulated, relatively quickly, by the PPNM. Programmes which promote relationship communication skills and explicit monogamy expectations may help reduce concurrency. Javanbahkt et al found that concurrency was common among African American, Hispanic and Asian women, and associated with risk of human papillomavirus HPV infection.
As described by Gorbach et al , reactive concurrent partnerships are possibly motivated by the desire to establish fairness in the relationship and jealousy; they are often deliberately casual in nature, and as a result, are associated with higher risk. Cross-sectional survey data suggest an association between involvement in sexual concurrency and having a non-monogamous partner.
Adimora et al found that men and women reporting a non-monogamous partner in the past year had odds of concurrency, 13 and 23 the odds, respectively, of those who reported only monogamous partners. We examined data from individuals enrolled in the Project on Partner Dynamics POPD , a longitudinal study of young adult heterosexual men and women in the Los Angeles area.
