Sexual risk-taking mediates the association between impulsivity and acquisition of sexually transmitted infections among hazardously drinking incarcerated women.

ABSTRACT: BACKGROUND:A growing literature has identified associations between impulsivity and negative behaviors such as sexual risk-taking among high-risk and/or vulnerable populations, but few studies have linked impulsivity to biological outcomes of sexual risk-taking. The main purpose of this study was to document associations among impulsivity, sexual risk-taking, and biological measures of sexually transmitted infection (STI+) in a sample of hazardously drinking incarcerated women. METHODS:Two hundred forty-five hazardously drinking incarcerated women self-reported alcohol consumption and consequences, impulsivity, and sexual behavior. RESULTS:Biological testing revealed a 22.9% prevalence rate for STI+. In this sample, sexual risk-taking fully mediated the association between impulsivity and likelihood of STI+. In addition, individuals reporting sexual activity with multiple partners were significantly more likely to test STI+ than those reporting sexual activity with a primary partner. CONCLUSION:These results support previous research on impulsivity by demonstrating that impulsivity leads to STI+ through risky behavioral choices. These findings also extend prior work by documenting this association using biologically confirmed measures in a vulnerable female population that carries multiple risk factors and thus warrants increased research attention.

Project description:BACKGROUND:Understanding the spread of sexually transmitted infections (STIs) in a population is of great importance to the planning and delivery of health services globally. The worldwide rise of HIV since the 1980's, and the recent increase in common STIs (including HPV and Chlamydia) in many countries, means that there is an urgent need to understand transmission dynamics in order to better predict the spread of such infections in the population. Unlike many other infections which can be captured by assumptions of random mixing, STI transmission is intimately linked to the number and pattern of sexual contacts. In fact, it is the huge variation in the number of new sexual partners that gives rise to the extremes of risk within populations which need to be captured in predictive models of STI transmission. Such models are vital in providing the necessary scientific evidence to determine whether a range of controls (from education to screening to vaccination) are cost-effective. METHOD AND RESULTS:We use probability sample survey data from Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3) to determine robust distributions for the rate of new partnerships that involve condomless sex and can therefore facilitate the spread of STIs. Different distributions are defined depending on four individual-level characteristics: age, sex, sexual orientation, and previous sexual experience. As individual behaviour patterns can change (e.g. by remaining in a monogamous relationship for a long period) we allow risk-percentiles to be randomly redrawn, to capture longer term behaviour as measured by Natsal-3. We demonstrate how this model formulation interacts with the transmission of infection by constructing an individual-based SIS-P (Susceptible-Infected-Susceptible-Protected) transmission model for the spread of a generic STI, and observing overall population demographics when varying the transmission probability within a partnership, recovery rate and the level of population protection (e.g. from vaccination where applicable).
