"We mostly focus on preventing pregnancy, we don't really focus on preventing HIV ": Young people's perceptions and priorities when preventing unplanned pregnancy and HIV.

In South Africa, the high rate of human immunodeficiency virus (HIV) infection among young people and unplanned pregnancies remains a concern. Using a qualitative approach, this study aimed to explore how young people between 18 and 24 years old perceive the risk of unplanned pregnancy and HIV, and how they give priority to and act to prevent both concerns. Fifty-four young people were recruited from three provinces in South Africa: KwaZulu-Natal, Eastern Cape, and Gauteng. Data collection took place between May and June in 2016. All data collection was carried out in person using a standardised discussion guide and a semi-structured interview guide in English. We conducted eight focus group discussions with young people and three in-depth interviews with young people who had become parents in their teens. We utilised thematic analysis grounded in a social constructionist framework to assess patterns and associations in the data. Respondents reported unplanned pregnancy and HIV as prevalent among their peers, but prioritised both concerns differently. Preventing pregnancy was a greater priority and threat than HIV. Respondents were less concerned about being infected with HIV which was perceived as invisible and not a death sentence because of the efficacy and ease of use of treatment. HIV was considered comparatively more manageable and less burdensome than other chronic illnesses and unplanned pregnancy. Our study suggests unplanned pregnancy and HIV prevention interventions should prioritise responding to young people's primary desire to control their fertility, but also encourage them to have holistic sexual and reproductive health goals that include HIV prevention. Our findings suggest a pressing need for biomedical therapies that offer combined HIV and pregnancy prevention for young people. Future programmes need to be agile and innovative in addressing young people's tendency to prioritise HIV and pregnancy differently, and they need to revive the sense of urgency to prevent HIV.

The Global Distribution and Epidemiology of Psychoactive Substance Use and Injection Drug Use Among Street-Involved Children and Youth: A Meta-Analysis.

Background: Globally, street-involved children and youth (SICY) who work and live on/of the streets are at higher risk of increased psychoactive substances and injecting drug use. Objectives: The present study aimed to identify the prevalence, distribution, sociodemographic factors, and risk-taking behaviors associated with psychoactive substances and injecting drug use among SICY. Methods: Studies in English published from December 1 1985 to July 1 2022, were searched for on PubMed, Scopus, Cochrane, and Web of Science to identify primary studies on psychoactive substances and injecting drug use among SICY. The pooled-prevalence estimates were obtained using a robust fixed-effects model. Results: The most commonly reported life-time and current psychoactive substance was tobacco followed by cannabis, LSD/ecstasy, cocaine, methamphetamine, heroin and injection drug use. The results showed that life-time and current prevalence of methamphetamine and cannabis use, as well as life-time prevalence of cocaine, LSD/ecstasy, heroin, tobacco, and injecting drug use increased as age rose while current prevalence of cocaine and tobacco use decreased as age rose. SICY who were male, homeless, had parents who had died, had history of substance use among family members or best friends, had experienced violence, had casual sex partners, had a history of working in the sex trade, and had unprotected sex were all related to psychoactive substance use and injecting drug use. Conclusions: Research examining this population suffers from lack of studies, therefore, improving the knowledge for interventions aimed at reducing risk behaviors, particularly those related to the transmission of sexually transmitted infections such as HIV is of great importance.

The Information-Motivation-Behavioral Skills Model and Unprotected Sex: Assessing the Model's Utility and Predictability Among Bar Patrons in Tshwane, South Africa.

The Information-Motivation-Behavioral skills (IMB) model has been a useful tool for understanding sexual risk behavior. However, its utility in predicting sexual risk behaviors among bar patrons, for whom the bar setting poses a higher risk of alcohol-related sexual risk behavior, has been underexplored. We assessed (1) the extent to which the IMB predicted number of episodes of unprotected sex in the past six months and (2) whether incorporating sex under the influence of alcohol and alcohol use improved the predictability of the model among bar patrons. Hierarchical regression models were conducted on data from 406 men and women from bars in rural areas of North-West province, South Africa. Behavioral skills were the sole IMB variable to predict unprotected sex with main partners (ß = - 0.40; p < .001), explaining 18% of the variance. Variance explained increased to 21% with addition of sex under the influence of alcohol (ß = 0.13; p = .019) and further increased to 26% with the addition of alcohol use (ß = 0.24; p < .001). Motivation (ß = - 0.21; p = .006) and behavioral skills (ß = - 0.21; p = .006) were the significant IMB predictors of unprotected sex with casual partners (explaining 15% of the variance). Variance explained increased to 22% with the addition of sex under the influence of alcohol (ß = 0.26; p = .001), but alcohol consumption was not an independent predictor of episodes of unprotected sex with casual partners. Interventions for improving HIV prevention behaviors among bar patrons should focus on enhancing individuals' behavioral skills and motivation and reducing their alcohol consumption.

Cross-Lagged Associations of Insecure Attachment Style, Alcohol Use, and Sexual Behavior During Emerging Adulthood.

Insecure romantic attachment style has been associated with greater substance use and higher risk sexual behavior, but the temporal nature of these associations is not well-understood. This study examined whether having a more insecure attachment style was associated with greater engagement in higher-risk sexual behavior over time and, if so, whether this was mediated by more frequent alcohol use. We used three annual waves of survey data from a diverse California cohort (N = 2371) who were assessed from ages 19 to 21-22 years. Separate cross-lagged models examined temporal associations of insecure romantic attachment style (anxious and avoidant), past month alcohol use frequency, and sexual behavior (number of sex partners, condomless sex with casual and steady partners). Attachment anxiety was not directly associated with sexual behavior. Rather, a consistent pattern across waves showed that greater attachment anxiety was associated with more frequent alcohol use at the next wave, which, in turn, was associated with having more sex partners and condomless sex with casual and steady partners one year later. In contrast, greater attachment avoidance was directly associated with having fewer sex partners, and its associations with condomless sex differed across partner type and assessment waves. Attachment avoidance was unrelated to alcohol use frequency. Results indicated that both anxious and avoidant attachment styles were associated with higher-risk sexual behavior, but in different ways and through different mechanisms. Future research may want to examine whether the effectiveness of sexual risk reduction programs for young people is enhanced by discussing attachment style and tailoring the curriculum accordingly.

Sexual enhancement expectancy, non-medical use of prescription drugs, and sexual risk behaviors in college students.

Background: American young adults have a high risk of sexually transmitted infections. Sexual risk behaviors may be influenced by psycho-behavioral factors, including substance use and sexual enhancement expectancy. Existing research suggested that substance use may mediate the relationship between sexual enhancement expectancy and sexual risk behaviors. The substance use literature also suggested that non-medical use of prescription drugs (NMUPD) was highly prevalent in college students and was associated with sexual risk. However, limited studies have examined NMUPD-related sexual enhancement expectancy. The current study examined the relationship among sexual enhancement expectancy, NMUPD, and sexual risk behaviors in college students. Methods: Online data were collected in 2016 from 453 US college students with lifetime NMUPD. All participants reported their (1) past-three-month NMUPD, (2) NMUPD sexual enhancement expectancy, and (3) sexual risk behaviors. Structural equation modeling was employed for data analysis. Results: Findings suggested significant associations of NMUPD with sexual enhancement expectancy and sexual risk behaviors. Sexual enhancement expectancy was indirectly associated with sexual risk behaviors through NMUPD. Conclusions: College students' sexual risk behaviors appear to be indirectly influenced by sexual enhancement expectancy through NMUPD. Future sexual risk reduction interventions should attend to sexual enhancement expectancy and NMUPD.

Sexual risk-taking among young Swedish men testing for STI.

OBJECTIVES: This study investigates sexual risk-taking among young men testing for sexually transmitted infections (STI). SAMPLING METHOD: 452 participants (aged 18-30) completed surveys concerning their backgrounds, sexual risk-taking, and experience with STI. RESULTS: Over one-third had used alcohol during their last sexual encounter, one-fifth were reluctant to use condoms due to concerns about erection difficulties, 14.7% had experienced sexual coercion and one-fifth reported having had contracted the most common STI, chlamydia trachomatis (CT). Older participants (aged 25-30) were more reluctant to use condoms because of erection worries and to report having had CT. Immigrant men reported more unprotected sex while men who have sex with men (MSM) were more exposed to sexual coercion than others, but less likely to use alcohol when having sex. CONCLUSIONS: There are important differences in sexual risk-taking within the group of young men testing for sexually transmitted infections which need to be taken into account in developing effective counselling and promotion strategies in sexual and reproductive health care. Further research on young men's sexual risk-taking is needed to broaden understanding of factors associated with young men's sexual health.

Dual-centered ANCOVA: Resolving contradictory results from Lord's paradox with implications for reducing bias in longitudinal analyses.

INTRODUCTION: Valid causal inferences are necessary to use developmental research to improve adolescent outcomes. What type of change should be analyzed to approximate causal inferences from longitudinal data? Difference-score and ANCOVA-type analyses often produce contradictory results, a problem known as Lord's paradox. This study investigates 2-group, 2-wave difference-score analyses and ANCOVA, and introduces a method that produces consistent results, namely dual-centered ANCOVA, which is compared to pretest matching. METHODS: These methods are tested first on two datasets simulated to fit each of Lord's contrasting results. The methods are then applied to data investigating the longitudinal associations of parent-adolescent discussions about sexual risks on subsequent unprotected sexual behaviors in 4753 American adolescents (62.2% whites). RESULTS: The results replicate Lord's contradictory results for all datasets. Dual-centered ANCOVA and pretest matching both produce consistent results, but dual-centered ANCOVA replicates the original results for difference-score analyses, whereas pretest matching replicates the original ANCOVA results. Thus, the two sets of consistent results differ from each other as much as the original discrepancy rather than reducing bias. CONCLUSION: The least biased analysis is the one whose null hypothesis best approximates a plausible change pattern to represent a no-treatment effect. When difference-score analyses are thought to approximate valid causal inferences as closely as ANCOVA-type analyses, dual-centered ANCOVA estimates the difference-score effect while retaining the advantages of ANCOVA in statistical power and covariate inclusion. These findings are widely applicable to longitudinal analyses that incorporate one or both of these basic methods to analyze change.

Young Adult Sexual Behavior in South Africa: How Important is Parental Social Support?

Risky sexual behavior exposes young adults to poor reproductive health outcomes. Parental social support is associated with reduced incidence of risky sexual behavior, but this association has not been adequately investigated in South Africa. We used data from Waves 1 and 3 of the Cape Area Panel Study (a longitudinal study of adolescents and young adults aged 14-22 years and living in the Cape Town metropolitan area) to investigate the associations between parental social support and young adult risky sexual behavior in South Africa. We conducted multivariable logistic regression analyses to assess whether lack of specific categories of parental social supports at wave 1 (baseline) are associated with higher risky sexual behaviors by young adults at wave 3 (follow-up). We found that young adults who never ate meals with their mothers and those who never discussed personal matters with their fathers had increased risks of multiple sexual partnerships. Also, young adults who never got pocket money or money for gifts from their mothers had increased risk to engage in unprotected sex during their first sexual encounter. Our findings suggest that eating family meals, discussing personal matters with youth, and providing them with pocket money, may protect young adults in South Africa from risky sexual behavior.

Condomless Sex and Psychiatric Comorbidity in the Context of Constrained Survival Choices: A Longitudinal Study Among Homeless and Unstably Housed Women.

We sought to identify the prevalence and independent correlates of condomless sex within a cohort of community-recruited homeless and unstably housed cisgender adult women who were followed biannually for 3 years (N = 143 HIV+ , N = 139 HIV-). Nearly half (44%) of participants reported condomless sex in the 6 months before baseline, which increased to 65% throughout the study period. After adjusting for having a primary partner, longitudinal odds of condomless sex among women with HIV were significantly higher among those reporting < daily use of alcohol or cannabis (AOR = 2.09, p =.002, and 1.88, p =.005, respectively) and PTSD (AOR = 1.66, p =.034). Among women without HIV, adjusted longitudinal odds of condomless sex were significantly higher for those reporting < daily methamphetamine use (AOR = 2.02, p =.012), panic attack (AOR = 1.74, p =.029), and homelessness (AOR = 1.67, p = .006). Associations were slightly attenuated when adjusting for sex exchange. Targeted HIV/STI programs for unstably housed women should address anxiety and trauma disorders, infrequent substance use, and housing challenges.

The Role of Pregnancy Concerns in the Relationship between Substance Use and Unprotected Sex among Adolescents.

BACKGROUND: Substance use and unprotected sex are prevalent among adolescents. The link between substance use and unprotected sex is well-established. Research has also highlighted how adolescents' attitudes and risk perceptions regarding unprotected sex, including concerns about pregnancy ("Getting pregnant would force me to grow up too fast"), are associated with unprotected sex and unplanned pregnancy. However, less research has examined the potential relationship between pregnancy concerns and substance use among adolescents. OBJECTIVES: The study prospectively examined (1) differences in pregnancy concerns across patterns of substance use and (2) whether pregnancy concerns mediate the relationship between substance use and later unprotected sex among a sample of middle and high school students. METHOD: 98 adolescents [M(SD) age = 14.28(1.68), 59.4% female, 59.4% black/African American] completed self-report measures of marijuana and alcohol use, pregnancy concerns, and unprotected sex across three time points over 6 months (T1-T3). RESULTS: Substance users (alcohol/marijuana) reported fewer pregnancy concerns compared to non-substance users (t = 2.99, p = .04). Pregnancy concerns at T2 mediated the relationship between T1 lifetime substance use and later unprotected sex (T3) (indirect effect: b = 0.10, CI[.01-.41]; direct effect: b = 0.15, p = .32), controlling for gender, age, and race. More frequent substance use (T1) was related to fewer pregnancy concerns at T2 (b = -0.10, p = .04); fewer pregnancy concerns were related to increased likelihood of later unprotected sex (b = -1.02, p = .02). CONCLUSIONS: Findings offer new insight into associations between substance use and unprotected sex and suggest that substance use and sexual health interventions should target pregnancy concerns.

"I am aware of the risks, I am not changing my behaviour": risky sexual behaviour of university students in a high-HIV context.

Unprotected sexual activity increases the risk of pregnancy and HIV and AIDS. More than three decades into the AIDS pandemic, the condom remains the most effective strategy for protecting against the dual risks of pregnancy and HIV and AIDS, but data from national surveys suggest that condom use among young people aged 15-24 is on the decline in South Africa. This study uses qualitative data from 20 in-depth interviews and one focus group to examine the risk behaviours of university students aged 18-24 years old, with particular emphasis on understanding the decline in the use of condoms. It is well documented that South Africa has one of the highest prevalence rates of HIV and AIDS in the world, however the findings of this study suggest that even though students were well informed about the perceived risks associated with unsafe sexual behaviours, they continue to engage in risk behaviours including unprotected sexual intercourse, multiple sexual partners and the use of alcohol. Male students were more likely than female students to report risky sexual behaviours. Condom use is occurring but not consistently. The majority of students did not use condoms during their first sexual encounter because of a lack of preparedness. Negative attitudes towards condoms continue to discourage students from using them consistently, especially those provided by the government. In light of this, it is recommended that rigorous efforts are directed towards challenging inaccurate perceptions about, and attitudes towards, condom use to promote consistency.

Modelling the impact of correlations between condom use and sexual contact pattern on the dynamics of sexually transmitted infections.

BACKGROUND: It is believed that sexually active people, i.e. people having multiple or concurrent sexual partners, are at a high risk of sexually transmitted infections (STI), but they are likely to be more aware of the risk and may exhibit greater fraction of the use of condom. The purpose of the present study is to examine the correlation between condom use and sexual contact pattern and clarify its impact on the transmission dynamics of STIs using a mathematical model. METHODS: The definition of sexual contact pattern can be broad, but we focus on two specific aspects: (i) type of partnership (i.e. steady or casual partnership) and (ii) existence of concurrency (i.e. with single or multiple partners). Systematic review and meta-analysis of published studies are performed, analysing literature that epidemiologically examined the relationship between condom use and sexual contact pattern. Subsequently, we employ an epidemiological model and compute the reproduction number that accounts for with and without concurrency so that the corresponding coverage of condom use and its correlation with existence of concurrency can be explicitly investigated using the mathematical model. Combining the model with parameters estimated from the meta-analysis along with other assumed parameters, the impact of varying the proportion of population with multiple partners on the reproduction number is examined. RESULTS: Based on systematic review, we show that a greater number of people used condoms during sexual contact with casual partners than with steady partners. Furthermore, people with multiple partners use condoms more frequently than people with a single partner alone. Our mathematical model revealed a positive relationship between the effective reproduction number and the proportion of people with multiple partners. Nevertheless, the association was reversed to be negative by employing a slightly greater value of the relative risk of condom use for people with multiple partners than that empirically estimated. CONCLUSIONS: Depending on the correlation between condom use and the existence of concurrency, association between the proportion of people with multiple partners and the reproduction number can be reversed, suggesting the sexually active population is not necessary a primary target population to encourage condom use (i.e., sexually less active individuals could equivalently be a target in some cases).

Associations with Unprotected Sexual Behavior Among HIV-Infected Drinkers in Western Kenya.

Approximately 71% of HIV-infected individuals live in sub-Saharan Africa. Alcohol use increases unprotected sex, which can lead to HIV transmission. Little research examines risky sex among HIV-infected individuals in East Africa who are not sex workers. The study purpose was to examine associations with unprotected sex in a high-risk sample of 507 HIV-infected sexually active drinkers in western Kenya. They were enrolled in a trial to reduce alcohol use. Past-month baseline alcohol use and sexual behavior were assessed using the Timeline Followback. A zero-inflated negative binomial model examined associations with occurrence and frequency of unprotected sex. Results showed heavy drinking days were significantly associated with unprotected sex occurrence across gender, and with unprotected sex frequency among women. Among women, transactional sex, alcohol-related sexual expectations, condom use self-efficacy, drinking-and-protected-sex days and age were associated with unprotected sex occurrence while alcohol-related sexual expectations, depressive symptoms and condom use self-efficacy were associated with unprotected sex frequency. Among men, alcohol-related sexual expectations, condom use self-efficacy, and age were associated with unprotected sex occurrence, while drinking-and-protected-sex days were associated with unprotected sex occurrence and frequency. Findings suggest robust relationships between heavy drinking and unprotected sex. Further research is needed elucidating the temporal relationships between drinking and unprotected sex in this population.

Alcohol Use and Unprotected Sex Among HIV-Infected Ugandan Adults: Findings from an Event-Level Study.

While alcohol is a known risk factor for HIV infection in sub-Saharan Africa (SSA), studies designed to investigate the temporal relationship between alcohol use and unprotected sex are lacking. The purpose of this study was to determine whether alcohol used at the time of a sexual event is associated with unprotected sex at that same event. Data for this study were collected as part of two longitudinal studies of HIV-infected Ugandan adults. A structured questionnaire was administered at regularly scheduled cohort study visits in order to assess the circumstances (e.g., alcohol use, partner type) of the most recent sexual event (MRSE). Generalized estimating equation logistic regression models were used to examine the association between alcohol use (by the participant, the sexual partner, or both the participant and the partner) and the odds of unprotected sex at the sexual event while controlling for participant gender, age, months since HIV diagnosis, unhealthy alcohol use in the prior 3 months, partner type, and HIV status of partner. A total of 627 sexually active participants (57% women) reported 1817 sexual events. Of these events, 19% involved alcohol use and 53% were unprotected. Alcohol use by one's sexual partner (aOR 1.70; 95% CI 1.14, 2.54) or by both partners (aOR 1.78; 95% CI 1.07, 2.98) during the MRSE significantly increased the odds of unprotected sex at that same event. These results add to the growing event-level literature in SSA and support a temporal association between alcohol used prior to a sexual event and subsequent unprotected sex.

Performance, power and condom use: reconceptualised masculinities amongst Western male sex tourists to Thailand.

Each year large numbers of Western men travel to Thailand for sex tourism. Although many will use condoms during their sexual encounters, others will not, potentially exposing themselves to the risk of acquiring sexually transmitted infections, including HIV. Although sex tourism in Thailand has been well documented, the social drivers underpinning voluntary sexual risk-taking through the avoidance of condoms remain poorly understood. Engaging with R.W. Connell's concept of hegemonic masculinity and drawing on data collected from 1237 online discussion board posts and 14 face-to-face interviews, this study considers the ways in which understandings and performances of masculinities may inform the sexual risk-taking behaviours of Western male sex tourists. It argues that for some of these men, unprotected sex is viewed not as a reckless behaviour but, instead, as a safe and appropriate masculine practice, supported by relationships that are often framed as romantic and within a setting where HIV is still largely considered a homosexual disease. With sex workers often disempowered to request safer sexual practices, and some men's attitudes towards unprotected sex resistant to external health promotion advice, the paper concludes by considering what this might mean for policy and practice.

Cognitive emotion regulation strategies among Chinese adolescents having unprotected sex: a latent profile analysis.

The association between cognitive emotion regulation strategy use and adolescents' risk behavior has long been emphasized. To identify coping profiles of Chinese adolescents having unprotected sex and to examine the characteristics and associations among those subgroups, 541 adolescents (age, 14-19 years) were screened from secondary schools in 10 Chinese cities. By latent profile analysis (LPA), the participants were identified into three latent profiles: the low reaction profile (LRP, N = 70), the medium reaction profile (MRP, N = 369), and the high reaction profile (HRP, N = 102) based on nine subscales of the Cognitive Emotion Regulation Questionnaire (CERQ). By one-way analysis of variance, chi-square tests, and multivariate logistic regression analysis, we found that: the HRP has the highest level of using eight strategies and the lowest unprotected sex, meanwhile the LRP has the lowest level of using nine strategies and the highest unprotected sex among three groups (both p < .05). The low response coping was more prevalent among boys and younger students. It indicates that more active cognitive coping, using both adaptive and maladaptive strategies, may associate with less unprotected sex. The programs of enhancing active copying may be targeted in interventions aiming to reduce adolescent unprotected sex.

[Qualitative study on unprotected sexual behaviors among male students who have sex with men in Beijing].

Objective: To investigate the related factors of unprotected sexual behaviors among male students who have sex with men in Beijing. Methods: Male students who have sex with men were recruited from May 2018 to July 2018 at two voluntary counseling and testing (VCT) clinics in Beijing by convenient sampling method. Information being collected during in-depth personal interviews with a semi-structured outline included ways to seek sexual partners, sexual partners characteristics, attitude of condom use, incidence and causes of unprotected sexual behaviors, rush poppers and alcohol use. The text information was summarized and analyzed by Nvivo 11.0 software. Results: A total of 35 male students who have sex with men were recruited and interviewed, the median of age was 22 years old (P(25)-P(75): 21-24 years old). We found that incomprehensive knowledge of condom use, low risk perception of non-anal sexual behaviors, rush poppers and alcohol use were risk factors of unprotected sexual behaviors on individual level. Besides, sex with regular sex partners, partners who were much older or not from campus, and insertive partners are more likely to be unprotected. Furthermore, refusal of condom use by sexual partners and low self-efficacy of decision-making on condom use were the main reasons for unprotected sexual behaviors among male student who have sex with men. Conclusion: Lack of condom use knowledge, low risk perception of non-anal sexual behaviors and insufficient ability to refuse non-condom requirements for regular sex partners, partners who were much older or not from campus, and insertive partners are related factors of unprotected sexual behaviors among male students who have sex with men.

'No Sweet in Sex': Perceptions of Condom Usefulness among Elderly Yoruba People in Ibadan Nigeria.

Emerging evidence has shown a gradual increase in sexually transmitted infections among elderly. This study explores the views of elderly Yoruba men and women (60+) on condoms use and its suitability against sexual infections. The research design was a sequential exploratory mixed method that consisted of vignettes based focus group discussion and a structured questionnaire. Twelve vignettes based Focus Group Discussion and a survey of 252 elderly Yoruba people (aged 60+) were carried out. The findings revealed limited awareness and experience with condoms. Few of the male (20.4%) and 2.8% of the female respondents felt condom use can prevent sexually transmitted infections. A marginally proportion of the females (29.2%) than the males (25.0%) perceived condom as more useful for younger people. Condom use as a preventive measure against sexual infections varies by gender and marital status (p = .000). Gender and marital status also had an influence on whether condom use could reduce sexual pleasures (p = 0.000). These findings offer strong support of the sexual pleasure hypothesis which is often invoked to explain attitude toward condom use in a variety of social and cultural contexts. Social marketing of condoms is urgently required to address misconceptions around condom use and encourage uptake among sexually active elderly people.

School, Supervision and Adolescent-Sensitive Clinic Care: Combination Social Protection and Reduced Unprotected Sex Among HIV-Positive Adolescents in South Africa.

Social protection can reduce HIV-risk behavior in general adolescent populations, but evidence among HIV-positive adolescents is limited. This study quantitatively tests whether social protection is associated with reduced unprotected sex among 1060 ART-eligible adolescents from 53 government facilities in South Africa. Potential social protection included nine 'cash/cash-in-kind' and 'care' provisions. Analyses tested interactive/additive effects using logistic regressions and marginal effects models, controlling for covariates. 18 % of all HIV-positive adolescents and 28 % of girls reported unprotected sex. Lower rates of unprotected sex were associated with access to school (OR 0.52 95 % CI 0.33-0.82 p = 0.005), parental supervision (OR 0.54 95 % CI 0.33-0.90 p = 0.019), and adolescent-sensitive clinic care (OR 0.43 95 % CI 0.25-0.73 p = 0.002). Gender moderated the effect of adolescent-sensitive clinic care. Combination social protection had additive effects amongst girls: without any provisions 49 % reported unprotected sex; with 1-2 provisions 13-38 %; and with all provisions 9 %. Combination social protection has the potential to promote safer sex among HIV-positive adolescents, particularly girls.

Number of Sexual Partners and Relationship Status Are Associated With Unprotected Sex Across Emerging Adulthood.

Sex with multiple partners, consecutively or concurrently, is a risk factor for contracting sexually transmitted infections (STIs) as multiple partner-partner contacts present increased opportunity for transmission. It is unclear, however, if individuals who tend to have more partners also use protection less reliably than those with sexual histories of fewer partners. Longitudinal data can elucidate whether an individual shows a consistent pattern of sex with multiple partners. We used latent class growth analyses to examine emerging adult survey data (N = 2244) spanning 10 waves of assessment across 6 years. We identified three trajectory classes described with respect to number of partners as (a) Multiple, (b) Single, and (c) Rare. Trajectory group, relationship status, and their interactions were tested as predictors of using protection against STIs and pregnancy at each wave. The Multiple Partners class had the greatest odds ratio of reporting sex without protection against STIs and pregnancy, followed by the Single and Rare classes. Exclusive relationship status was a risk factor for unprotected sex at earlier waves, but a protective factor at most later waves. There was no significant interaction between relationship status and trajectory class in predicting use of protection. The Multiple Partners class reported more permissive values on sex and an elevated proportion of homosexual behavior. This group overlaps with an already identified at-risk population, men who have sex with men. Potential mechanisms explaining the increased risk for sex without protection, including communication, risk assessment, and co-occurring risk behaviors are discussed as targets for intervention.
