Serial Monogamy and Biologic Concurrency: Measurement of the Gaps Between Sexual Partners to Inform Targeted Strategies
American journal of epidemiology, 2013Co-Authors: Catherine H Mercer, Claudia Estcourt, Frances Keane, Catherine R H Aicken, Clare Tanton, M. Gary Brook, Jackie CassellAbstract:Having multiple sexual partners concurrently increases the risk of transmission of a sexually transmitted infection. Even if partnerships do not overlap, transmission potential exists when the gap between partnerships is shorter than the remaining infectious period. In the present article, we quantify the gap between partners to assess transmission potential using data collected by a cross-sectional survey of 2,203 genitourinary medicine clinic patients in England in 2009. Questionnaires asked about patients' 3 most recent partnerships. Gaps were calculated as time (days) between the last sexual encounter with a former partner and the first sexual encounter with the next partner. Among 1,875 patients who reported 1 or more partners in the previous 3 months, 47.6% of men and 27.7% of women reported 2 or more partners. Forty-two percent of the gaps were negative (i.e., partnerships that were concurrent); the median gaps were −7 and −17 days for men and women, respectively (i.e., overlaps were 7 and 17 days for men and women, respectively). Although half of the gaps were positive (Serially monogamous partnerships), many were of short duration; the median gaps were 14 and 24 days for men and women, respectively. In over half of the gaps, condoms were used inconsistently with one or both partners, and in one-quarter, condoms were never used with either partner. There is thus a high potential for sexually transmitted infections, as even if partnerships are not behaviorally concurrent, they may be biologically concurrent. These data have important implications for designing and targeting effective health promotion messages.

o2 s1 02 is concurrency the new Serial Monogamy evidence from a large survey of people attending contrasting genitourinary medicine gum clinics in england
Sexually Transmitted Infections, 2011Co-Authors: C H Mercer, Crh Aicken, Nicola Low, Claudia Estcourt, Peter J White, Frances Keane, Gary Brook, Greta Rait, Jackie CassellAbstract:Background Concurrency is an important risk behaviour for STI transmission at the population level, yet few surveys ask detailed questions about concurrency. Even if partnerships do not overlap, there is potential for STI transmission if the gap between the end of one partnership and the start of the next is short. We examined the prevalence of concurrency, quantified the gap between partners and examined gender differences in a high-risk population. Methods Cross-sectional survey of 2203 people attending four contrasting GUM clinics in England in 2009. Attendees completed a questionnaire including questions about their three most recent partnerships in the 3 months prior to attending GUM. Gaps between partners were calculated as the time between most recent sex with a previous partner and first sex with a more recent partner. Partnerships were considered concurrent if the gap was negative. Results 92% of attendees reported sex partner(s) in the last 3 months, yet, while the median number of partners was 1387 men (48%) and 294 women (28%) reported 2+ partners in this time (p 4 weeks. Conclusions The majority of GUM attendees reported few partners in the last 3 months, yet half of those with 2+ partners had concurrent partnerships, such that concurrency is as common as Serial Monogamy in this population. These partnerships typically overlapped by a number of weeks and condoms were seldom used, if at all. Among the Serially monogamous, sex with a new partner within days of last sex with a former partner was common so the potential for STI transmission is high. Understanding concurrency and the gaps experienced by high-risk individuals is important for ensuring that health promotion and partner notification are delivered appropriately and effectively.

Marital Dissolution and Child Educational Outcomes in San Borja, Bolivia
Human Nature, 2016Co-Authors: Kristin SnopkowskiAbstract:Serial Monogamy is likely an adaptive mating strategy for women when the expected future fitness gains with a different partner are greater than expected future fitness with one’s current partner. Using interview data from more than 400 women in San Borja, Bolivia, discrete-time event history analyses and random effects regression analyses were conducted to examine predictors of marital dissolution, separated by remarriage status, and child educational outcomes. Male income was found to be inversely associated with women’s risk of “divorce and remarriage,” whereas female income is positively associated with women’s risk of “divorce, but not remarriage.” Children of women who divorce and remarry tend to have significantly lower educational outcomes than children of married parents, but women with higher incomes are able to buffer their children from the negative educational outcomes of divorce and remarriage. Counter to predictions, there is no evidence that women with kin in the community have a significant difference in likelihood of divorce or a buffering effect of child outcomes. In conclusion, predictors of divorce differ depending on whether the woman goes on to remarry, suggesting that male income may be a better predictor of a Serial Monogamy strategy whereas female income predicts marital dissolution only. Thus, women who are relatively autonomous because of greater income may not benefit from remarriage.

Age at Menarche and Risky Sexual Partnerships in Adulthood: Does a Biosocial Model Explain Any Associations?
Journal of women's health (2002), 2013Co-Authors: Jennifer Nield, Brianna M. Magnusson, Derek A. Chapman, Kate L. LapaneAbstract:Abstract Background: The purpose of this study was to examine the association between menarcheal age and subsequent sexual partnering in women aged 21–44 years. Methods: Data from the 2006–2010 National Survey of Family Growth were used (n=7,962). Menarcheal age was defined as ≤11, 12–14, or ≥15 years. Sexual partnering was defined as being concurrent, Serially monogamous or monogamous in the previous year. Polytomous logistic regression models evaluated the association between age of menarche and sexual partnering. Results: Nearly 6% reported concurrent partnerships and ∼4% Serial Monogamy. Age of menarche was not associated with subsequent concurrent sexual partnering (adjusted odds ratio relative to ≥18 years [aOR≤11]: 1.09; 95% confidence interval [CI]: 0.57–2.09; aOR12–14: 1.13; 95% CI: 0.64–1.99) or Serial Monogamy (aOR≤11: 0.75; 95% CI: 0.41–1.38; aOR12–14: 0.71; 95% CI: 0.39–1.29). Conclusions: Early menarche is not a risk factor for sexual partnering in adulthood. However, menarche provides an op...

Gap length: an important factor in sexually transmitted disease transmission.
Sexually transmitted diseases, 2003Co-Authors: Julie R Kraut-becher, Sevgi O. AralAbstract:Background Sexually transmitted disease (STD) transmission may occur if the time between dissolution and formation of sex partnerships, the gap, is shorter than mean duration of infectivity of STDs. Goal The goal was to examine gaps reported by a nationally representative sample of reproductive-age women. Study design Data on women's sex partnership dynamics were collected from the 1995 National Survey of Family Growth (NSFG). Gap was defined as the time between first sex with current/most recent partner and last sex with previous partner. Results One third of women reported negative gaps (concurrent partnerships). Among the women who reported positive gaps (Serial Monogamy), more than half switched partners in time periods shorter than the mean infectivity periods of some bacterial STDs. Adolescents and women with past STD diagnoses reported shorter gaps than any other group. Conclusion Given that many STDs are often asymptomatic, short gaps may present a problem if women and their partners are not routinely screened for STDs.

Correlates and Predictors of Risky Sexual Partnering
2013Co-Authors: Jennifer NieldAbstract:CORRELATES AND PREDICTORS OF RISKY SEXUAL PARTNERING By Jennifer A. Nield, Ph.D. A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy at Virginia Commonwealth University. Virginia Commonwealth University, 2013. Major Director: Derek A. Chapman, Ph.D. Assistant Professor, Department of Family Medicine and Population Health, Division of Epidemiology, School of Medicine, Virginia Commonwealth University Introduction: Sexually Transmitted Diseases, including HIV/AIDS, continue to be a major burden in the United States. Sexual partnering behaviors contribute to the spread of STDs. Sexual concurrency has been shown to exponentially increase STD prevalence in populations. Serial Monogamy with short periods between sexual partners also introduces risk. Methods: We identified sexually active men and women from the 2006-2010 National Survey of Family Growth (NSFG) and used sub sets for each particular study. Sexual partnering was defined as being concurrent, Serially monogamous or monogamous in the previous year. Polytomous logistic regression models were developed to evaluate the associations between age of sexual debut among adult men, age of menarche and discordant heterosexual identity and behavior among all women and sexual partnering patterns. Descriptive, mediation, subpopulation and stratified analyses were also conducted. Results: Sexual debut < 15 and 15-17 years was associated with concurrency (adjusted odds ratio (aOR)
