Introduction Understanding the risk factors for behavioral patterns in sexual relationships play a significant role in the reduction of the transmission of HIV/AIDS and other sexually transmitted infections. Objective To investigate individual and community level factors on the lifetime number of sexual partners of women in Eswatini Material and methods The study was a secondary cross-sectional analysis of the 2014 Eswatini Multiple Indicator Cluster Survey (MICS). A total of 2,832 women aged 15–49 years were asked in total, how many different people have you had sexual intercourse in your lifetime. The multilevel negative binomial regression model was used to analyze the data. Results The overall mean number of lifetime sexual partners was 2.78 (95% CI: 2.66, 2.91) in 2014. Compared to women aged 15–19, those aged 20 years and older, formerly married or never married reported more lifetime sexual partners compared to currently married women. Those that were aged 15 years and older at sexual debut reported fewer lifetime sexual partners compared to those that were aged less than 15 years. Compared to women that used a condom at last sexual intercourse, those that did not use a condom at last sexual encounter reported fewer lifetime sexual partners. Relative to women that lived with their sons and daughters, those that did not live with their sons and daughters reported more lifetime sexual partners. Women that lived in the Shiselweni and Lubombo regions reported fewer lifetime sexual partners compared to those residents in the Hhohho region. Conclusion Overall, lifetime sexual partners in Eswatini was significantly associated with individual characteristics and is unique across regions. Programs that aim to elucidate the factors associated with incident HIV infections among women in Eswatini should focus on individual and community-level factors that are associated with multiple sexual partnerships, which in turn might increase the risk of HIV exposure.

The Impact

Abstract Increasing human papilloma virus (HPV) vaccination coverage is one of the key approaches to preventing cervical cancer globally. However, some argue that HPV vaccine recipients may engage in risky compensatory sexual behaviours because of perceived protection afforded by the vaccine. Therefore, we investigated the impact of a wide-scale HPV vaccination programme on sexual behaviours among adolescent women in Rwanda—the first African country to implement a national HPV vaccination. We identified a cohort of women who were eligible for the HPV vaccination and those who were not eligible from the most recent Rwanda Demographic and Health Survey. We used a quasi-experimental regression discontinuity design, exploiting the quasi-random change in HPV vaccination eligibility in 2011, to compare sexual behaviours among vaccinated and unvaccinated adolescent women. We studied the impact of the vaccination on reported sexual intercourse, average number of sexual partners and teenage pregnancy across the vaccination eligibility threshold. Our analysis included 3052 adolescent women (mean age: 18.6 years), of whom 58% were eligible for HPV vaccination. Nearly one in five adolescents reported having had sexual intercourse (18.5%). The average reported lifetime number of sexual partners was 1.41. The proportion of teenage pregnancy was 5.3%. We found no evidence that HPV vaccination was associated with any significant changes across the eligibility threshold in reported sexual behaviours we studied: no significant increase in the proportion of having sexual intercourse [odds ratio (OR): 0.80, 95% confidence interval (CI): 0.57–1.12; P = 0.19], in lifetime number of sexual partners (rate ratio 0.99, 95% CI: 0.83–1.17, P = 0.91) and in the proportion of teen pregnancies (OR 1.05, 95% CI: 0.50 to 2.20, P = 0.89) at the eligibility threshold. The Rwandan national HPV vaccination programme did not increase sexual behaviours among adolescent women, assuaging concerns of engaging in risky compensatory sexual behaviours some have feared.

Abstract Background HPV attributable oropharyngeal cancer (HPV-OPC) incidence is increasing in many high-income countries among men. Factors associated with oral HPV persistence, the precursor of HPV-OPC, is unknown. Data from the HPV Infection in Men (HIM) study which followed participants >7 years were utilized to examine rates of persistence and associated factors. Methods Oral gargle samples from 3095 HIM study participants were HPV genotyped using SPF10 PCR-DEIA-LiPA25 assay. Oral HPV persistence for individual and grouped high-risk HPV types among 184 men positive for any high-risk HPV at their oral baseline visit was assessed at 6-month intervals. Factors associated with grouped high-risk HPV and HPV16 persistence were examined using logistic regression. Kaplan-Meier curves were constructed to examine median time to HPV clearance overall, and by selected risk factors. Results Among the 7 HPV vaccine types, HPV33 had the longest median duration (7.6 months) followed by HPV16 and HPV45 (6.4 months). 10-30% of oral high-risk HPV infections persisted >24 months. Six months persistence of oral high-risk HPV infections was positively associated with age and gingivitis and negatively associated with lifetime number of sexual partners, while twelve months persistence was only inversely associated with lifetime number of sexual partners. Oral HPV16 persistence was positively associated with baseline HPV16 L1 antibody status. Conclusions 18% of HPV16 infections persisted beyond 24 months potentially conferring higher risk of HPV-OPC among these men. Older age appears to be an important and consistently reported factor associated with oral high-risk HPV persistence. More studies among healthy men are required to understand the progression of oral HPV infection to HPV-OPC.

BackgroundWe investigated sex-specific associations between lifetime number of sexual partners and several health outcomes in a large sample of older adults in England.MethodsWe used cross-sectional data from 2537 men and 3185 women aged ≥50 years participating in the English Longitudinal Study of Ageing. Participants reported the number of sexual partners they had had in their lifetime. Outcomes were self-rated health and self-reported limiting long-standing illness, cancer, coronary heart disease, and stroke. We used logistic regression to analyse associations between lifetime number of sexual partners and health outcomes, adjusted for relevant sociodemographic and health-related covariates.ResultsHaving had 10 or more lifetime sexual partners was associated with higher odds of reporting a diagnosis of cancer than having had 0–1 sexual partners in men (OR 1.69, 95% CI 1.01 to 2.83) and women (OR 1.91, 95% CI 1.04 to 3.51), respectively. Women who had 10 or more lifetime sexual partners also had higher odds of reporting a limiting long-standing illness (OR 1.64, 95% CI 1.15 to 2.35). No other statistically significant associations were observed.ConclusionsA higher lifetime number of sexual partners is associated with increased odds of reported cancer. Longitudinal research is required to establish causality. Understanding the predictive value of lifetime number of sexual partners as a behavioural risk factor may improve clinical assessment of cancer risk in older adults.

Abstract Background and aims: Condom use at sexual debut is associated with subsequent condom use and with decreased risk of sexually transmitted infections. There is a dearth of data on determinants of condom use at first sexual intercourse. We aimed to determine factors associated with condom use at first sexual intercourse before marriage among Vietnamese adolescents and youths. Methods: The study involved the analysis of data from the Survey Assessment of Vietnamese Youth, 2003, the first nationally representative survey of young people in Vietnam. The survey included 7584 adolescents and youths aged 14–25 years. In this study, data of 605 adolescents and youths who had engaged in premarital sex were analyzed for factors associated with condom use using descriptive analyses, and regression techniques, allowing for sampling weights, clustering and stratification. Results: Of 605 adolescents and youths who had engaged in premarital sex, 28.6% reported condom use at first sexual intercourse. Condom use at sexual debut was less common in females than males [odds ratio (OR)=0.15; 95% confidence interval (95% CI)=0.07–0.30] and less common in those who experienced peer pressure to engage in social higher risk behaviors (OR=0.57; 95% CI=0.32–0.99). Condom use was more common if a friend/acquaintance or a stranger/sex worker was the first sexual partner (OR=2.20; 95% CI=1.16–4.17 and OR=17.90; 95% CI=6.88–46.54) respectively, each compared with fiancé/boyfriend/girlfriend as first sexual partner. Conclusions: These data suggest that approximately one in three unmarried Vietnamese youths used a condom at first sexual intercourse. Gender, peer pressure and the nature of the relationship to the first sexual partner were independently associated with condom use. These results can inform programs directed at preventing HIV and other sexually transmitted infections among young Vietnamese.

Sex With Men

Background: Men who have sex with men (MSM) university students were more likely to be infected with HIV than the general population due to various reasons, including having multiple sexual partners, having anal sex without a condom, and using alcohol and drugs. The objective of this study was to investigate the factors associated with multiple sexual partners among MSM university students in northern Thailand. Methods: The participants of this study were 139 MSM university students. The number of sexual partners in the last 12 months was used as the main outcome variable. Information was collected using an online self-administered questionnaire. The number of sexual partners for categories of participants was described as median and interquartile range. Factors that were independently associated with multiple sexual partners were identified using binary logistic regression analysis. Results: Findings showed that seeking sexual partners online (AOR = 1.72; 95% CI 3.10 - 44.29), drinking alcohol within the last 12 months (AOR=9.73; 95% CI 1.38 - 68.47), and having a self-perception of HIV risk (AOR=3.63; 95% CI 1.15 - 11.50) were independently associated with having multiple sexual partners. Conclusion: Health agencies and universities should develop strategies to promote life skills related to sexual responsibility, appropriate use of online media, and reduction of alcohol consumption among MSM university students.

AbstractBackgroundWomen’s reproductive factors include their age at menarche and menopause, the age at which they start and stop having children, and the number of children they have. Studies that have linked these factors with disease risk have largely investigated individual reproductive factors and have not considered the genetic correlation and total interplay that may occur between them. This study aimed to investigate the nature of the relationships between eight female reproductive factors.MethodsWe used data from the UK Biobank and genetic consortia with data available for the following reproductive factors: age at menarche, age at menopause, age at first birth, age at last birth, number of births, being parous, age at first sex and lifetime number of sexual partners. Linkage disequilibrium score regression (LDSC) was performed to investigate the genetic correlation between reproductive factors. We then applied Mendelian randomization (MR) methods to estimate the causal relationships between these factors. Sensitivity analyses were used to investigate directionality of the effects, test for evidence of pleiotropy and account for sample overlap.ResultsLDSC indicated that most reproductive factors are genetically correlated (rg range: |0.06 – 0.94|), though there was little evidence for genetic correlations between lifetime number of sexual partners and age at last birth, number of births and ever being parous (rg < 0.01). MR revealed potential causal relationships between many reproductive factors, including later age at menarche (1 SD increase) leading to a later age at first sexual intercourse (Beta (B)=0.09 SD, 95% confidence intervals (CI)=0.06,0.11), age at first birth (B=0.07 SD, CI=0.04,0.10), age at last birth (B=0.06 SD, CI=0.04,0.09) and age at menopause (B=0.06 SD, CI=0.03,0.10). Later age at first birth was found to lead to a later age at menopause (B=0.21 SD, CI=0.13,0.29), age at last birth (B=0.72 SD, CI=0.67,0.77) and a lower number of births (B=-0.38 SD, CI=-0.44,-0.32).ConclusionThis study presents evidence that women’s reproductive factors are genetically correlated and causally related. Future studies examining the health sequelae of reproductive factors should consider a woman’s entire reproductive history, including the causal interplay between reproductive factors.

AbstractAdolescence is characterized by significant biological and psychological changes. During this time, the increased production of androgens leads to increased sexual behavior, and this may contribute to early initiation of sexual activity. The objectives of the present cross-sectional study of adolescents enrolled in state schools in the city of Ribeirão Preto, state of São Paulo, Brazil, were to determine the average age at the first sexual intercourse (sexarche), the average number of sexual partners, and the frequency of contraceptive and condom use. Information on the age at sexarche, number of sexual partners, use of different contraceptive methods, and use of condoms were obtained using a semistructured questionnaire. Quantitative variables are expressed as means and standard deviations (SDs), and qualitative variables as absolute and relative frequencies. The chi-squared test was used for comparisons of qualitative variables, and the Student t-test for comparisons of continuous variables. All statistical analyses were performed using SAS (version 9.4, North Carolina State University, USA). We evaluated 202 students who answered the questionnaire, 69 males (36.36%) and 133 females (63.64%). The age at sexarche for men ranged from 7 to 18 years old, and for women from 7 to 17 years old. Forty-eight girls (36.01%) and 21 boys (30.43%) were in the first year of high school, 66.94% of adolescents reported sexual intercourse, and 56.25% used a condom during the first sexual intercourse. A total of 36.72% of students said they had safe sex most of the time, and 83.59% said that the first sexual intercourse happened because they “had a crush on” the other person.

In this study, the relationships between attachment patterns and relationship outcomes were explored through the mechanism of sexuality with two large samples from the U.S. In the first sample ( N = 4,834), the associations between insecure attachment patterns, the number of committed and casual sexual partners, timing of sexual debut, and relationship status were explored. In the second sample, a nationally representative sample of recently married couples ( N = 4212), an actor–partner model was used to explore the associations with attachment on the number of sexual partners and sexual timing and their subsequent influence on relationship and sexual satisfaction over two time points. The results indicated that, for Sample 1, insecure attachment was associated with both the number of casual and committed sexual partners and an increased likelihood of being single for men and women. For Sample 2, the actor–partner measures of attachment were associated with relationship and sexual satisfaction over two time points but had weak associations with the number of sexual partners and sexual timing.

PurposeHigh-risk sexual behaviour is a factor affecting the health of sexual minority students, yet few related studies have been completed among Chinese students. This article explores the distribution of sexual minority groups and its association with high-risk sexual behaviours and symptoms of sexually transmitted infections(STIs) among Chinese college students.MethodsAn internet-based questionnaire was applied, and a sample of 17 966 surveys from 130 Chinese colleges was collected. Based on their self-reports, participants were classified into the following groups: homosexual male or female, heterosexual, bisexual, and sexual orientation unknown. High-risk sexual behaviours were defined as having sexual intercourse before the age of 18 years, having one's sexual debut with a non-regular partner, having had more than four sexual partners before investigation, and having mostly had sexual intercourse without using condoms. Logistic regression models were constructed to analyse the associations.ResultsThe proportions of the homosexual males and females, and the bisexual groups were 1.62%, 0.88% and 5.07%, respectively. Homosexual males were more likely to have their sexual debut with a non-regular partner (OR 4.79, 95% CI 3.38 to 6.78), having more than four sexual partners (OR 5.81, 95% CI 4.06 to 8.32), having their sexual debut before the age of 18 years (OR 1.92, 95% CI 1.34 to 2.76), and not using condoms for most episodes of sexual intercourse (OR 1.47, 95% CI 1.00 to 2.17). Similar associations also existed among homosexual females. A positive association between sexual orientation and having symptoms of STIs (OR 1.49, 95% CI 1.02 to 2.18) was found among homosexual males.ConclusionsSexual minority groups among Chinese college students had a greater risk of engaging in high-risk sexual behaviours and having STI symptoms. Future studies and interventions should focus on this population.
