Context: Heterosexual transmission has been found to be the major route of HIV infection in Nigeria. Thus prevention of HIV infection by reducing risky behaviors has been identified as a public health priority. This study examines regional pattern and correlates of gender differences in HIV risk behaviors among Nigerian youths aged 15-24 years. As different geo-political regions have specific gender ideologies and practices, there is need to find out if gender differences in Nigeria regions drive HIV risk behaviors among youths. Method: Data from the 2003 Nigeria Demographic and Health Survey were analyzed for never married, sexually experienced 342 males and 630 females. Multiple sex partnerships and pattern of condom use were the HIV risk behaviors examined. Respondents were asked the number of sexual partners in the last 12 months while pattern of condom use is a composite variable of four items in the 2003 NDHS. Univariate, bivariate, and multivariate analyses were done using STATA 9.SE. Binary and multinomial logistic models were used for multivariate analyses. Results: The study shows that there is high level of risk behaviours in the population. This cuts across gender and regions. For instance, 54% of males and 69% of females engage in inconsistent condom use and 30% of males and 9% of females in multiple sex partnership. This pattern is consistent across the regions. It is also shown that while correlates of HIV risk behaviours vary by gender, its regional variation by gender is inconsistent. The study highlights inconsistent gender differentiation by regions. Further investigation is necessary to explain this observation.

Background. While much progress has been made, HIV remains a major global public health problem. South Africa remains home to the highest number of people living with HIV (7.1 million) in the world. Despite remarkable progress in the past decade, adolescent girls and young women aged 15-24 (AGYW) remain at higher risk of HIV exposure and infection than other groups. We do not know enough about AGYW HIV knowledge and perceptions, although it is likely an important factor to consider in AGYW's HIV risk. This paper investigates knowledge and perceptions about HIV risk behaviours and explores associations with demographic and behavioral characteristics among AGYW in South Africa. Methods. This sub-study is based on the 2012 South African National HIV Prevalence, Incidence and Behaviour Survey, a cross-sectional population-based household survey. A multistage stratified cluster sampling approach was employed to select the study population. Multivariate logistic regression was used to determine associations or factors which were associated with HIV knowledge. Results. Among the sample of 3700 AGYW aged 15-24 years, White [OR=2.44 (95% CI: 1.48-4.03), p=0.001] and Indian [OR=3.85 (95% CI: 2.39-6.18), p=0.000] AGYW were associated with high HIV knowledge compared to Black Africans. AGYW in urban informal [OR=0.64 (95% CI: 0.45-0.90), p=0.011] and rural informal [OR=0.57 (95% CI: 0.33-0.98), p=0.043] were associated with low HIV knowledge compared to urban formal settings. AGYW in Eastern Cape [OR=0.69 (95% CI: 0.48-1.00), p=0.048], KwaZulu-Natal [OR=0.69 (95% CI: 0.48-0.99), p=0.044], North West [OR=0.50 (95% CI: 0.32-0.77), p=0.002] and Limpopo [OR=0.44 (95% CI: 0.27-0.71), p=0.001] provinces were associated with low HIV knowledge compared to AGYW in Western Cape. Unemployed AGYW were associated with low HIV knowledge [OR=0.57, p=0.001]. While AGYW with higher levels of education: grade 12 [OR=1.66 (95% CI: 1.04-2.64), p=0.034] and tertiary [OR=2.68 (95% CI: 1.47-4.89), p=0.001] were associated with high HIV knowledge. AGYW having had sex in the last 12 months were associated with high HIV knowledge [OR=1.70 (95% CI: 1.08-2.72), p=0.023]. On the contrary, having multiple sexual partners in the last 12 months was associated with low HIV knowledge [OR= 0.60 (95%CI: 0.39-0.99), p=0.045] compared to AGYW that had 1 sexual partner in the last 12 months. AGYW with a low risk of alcohol use were associated with high HIV knowledge [OR=1.4 (95% CI: 1.02-1.87), p=0.039] compared to AGYW that abstained from alcohol. The final multivariate logistic regression model showed that AGYW in urban informal settings have low HIV knowledge [aOR=0.59 (95% CI: 0.35-0.99), p=0.046] among all geotypes. Conclusion. Overall, the main findings show a lack of knowledge among AGYW across race, geotype, province and sexual activity. More specifically that low HIV knowledge was associated with AGYW who were Black South Africans, living in informal settings, from Eastern Cape, KwaZulu Natal, North West and Limpopo, unemployed, had lower levels of education, and have multiple sexual partners. However, in the final multivariate analysis, only geotype stood out, indicating that there is an HIV knowledge deficit in urban informal settings. This can be addressed through the promotion of knowledge through education, equitable and accessible availability of education and sexual and reproductive health services, and HCT and support among AGYW living in urban informal settings.

HIV risk assessment models use multiple risk factors to build composite index scores to evaluate population level HIV risk. In this report, four risk assessment models were applied to a dataset with demographic, biological, and behavioral risk factors from 927 individuals in high and low HIV burden zip code groups in metro Atlanta, GA. Predictive ability of the risk assessment models were evaluated by comparing their sensitivity and specificity, area under the ROC curve, and mean score difference between high-burden and low-burden zip code area. The results show that the proportion of study participants who scored high in the risk assessment method are significantly greater in high-HIV burden zip code area than in low-HIV burden zip code area in all four risk assessment models. The Clinical Decision Rule risk-scoring model showed the best predictive ability of HIV risk and Binary Risk Indicator model showed the best predictive ability in predicting the residence zip code area.

The purpose of this study was to investigate relationships between four personality styles and two important indications of HIV risk behavior, at intake and 3-month follow-up, among a sample of adolescents participating in court-mandated substance abuse treatment in conjunction with an HIV prevention intervention. This study involved a secondary analysis of data from a NIDA funded project (1R01DA011875-01, R. Malow, PI). Predictor variables included levels of antisocial (unruly), dependent(submissive), avoidant (inhibited), and borderline (borderline tendency) personality styles drawn from scales of the Million Adolescent Clinical Inventory (MACI). Criterion variables included number of sexual partners and percentage of sex acts unprotected, derived from the Risk Behavior Assessment (RBA). A series of hierarchical regression analyses were conducted to test study hypotheses. Analyses controlled for age, ethnicity, education, gender, intervention status, the three personality variables not central to the hypothesis being tested, and baseline values of sexual risk behavior, when relevant. Results from the multiple regression analyses failed to support study hypotheses,indicating that adolescent personality styles were not important predictors of HIV risk behavior. Results are discussed within the context of the relevant literature. Study limitations and recommendations for future research are noted.

Adverse childhood experiences-including parental and familial factors such as parental substance abuse, parental mental health problems, parental incarceration, parental unemployment and family violence, and personal factors such as physical, sexual, and emotional abuse- have been shown to strongly affect health risk behaviours in adulthood in the general population and are thus important in the health status of an individual. However, studies of people who use injection drugs have generally focused on disease seroprevalence and risk behaviours without considering their psychosocial histories.<p> In the 2000 Regina Seroprevalence and Risk Behaviours Study, 255 people who use injection drugs completed a standardized, confidential, and anonymous interview which included questions on adverse childhood experiences and injection-related and sexual risk behaviours. Associations among and between participants' reported adverse childhood experiences and subsequent risk behaviours were tested. Demographic factors were also considered, and general linear models of factors associated with risk behaviours were developed. <p> The rates of adverse childhood experiences and risk behaviours reported were very high. Several of the adverse childhood experiences studied were related to increased risk behaviours. The factors associated with injection-related risk behaviours were similar to those associated with sexual risk behaviours. The impact of adverse childhood experiences on risk behaviours was found to be cumulative; the more adverse childhood experiences the participants reported, the more risk behaviours they also reported. This information provides a unique opportunity to address these problems in the treatment and prevention of injection drug use. Supplementary research is needed to further elucidate the factors associated with high-risk behaviours in people who use injection drugs.

The United States continues to be affected by the HIV/AIDS epidemic, and now public health is faced with new challenges in mitigating the spread of the disease. African-Americans are disproportionately affected by HIV and a further understanding about the factors that influence high risk sexual behaviors needs to be continuously examined. The aim of this study was to understand and compare the the perception of HIV risk and factors associated with risk perception in high risk adult and adolescent groups. After multivariate analysis, having multiple partners was the only predictor of an increased risk perception among adults. Among adolescents, no significant relationship was found between HIV risk indicators and having an increased HIV risk perception. Both adults and adolescents appeared to underestimate their HIV risk based on their reported risk sexual behaviors. More work is necessary to help adolescents accurately assess their risk of infection.

This study examines the influence of acculturative stress on substance use and HIV risk behaviors among recent Latino immigrants. The central hypothesis of the study is that specific religious coping mechanisms influence the relationship that acculturative stress has on the substance use and HIV-risk behaviors of recent Latino immigrants. Within the Latino culture religiosity is a pervasive force, guiding attitudes, behaviors, and even social interactions. When controlling for education and socioeconomic status, Latinos have been found to use religious coping mechanisms more frequently than their Non-Latino White counterparts. In addition, less acculturated Latinos use religious coping strategies more frequently than those with higher levels of acculturation. Given its prominent role in Latino culture, it appears probable that this mechanism may prove to be influential during difficult life transitions, such as those experienced during the immigration process. This study examines the moderating influence of specific religious coping mechanisms on the relationship between acculturative stress and substance use/HIV risk behaviors of recent Latino immigrants. Analyses for the present study were conducted with wave 2 data from an ongoing longitudinal study investigating associations between pre-immigration factors and health behavior trajectories of recent Latino immigrants. Structural equation and zero-inflated Poisson modeling were implemented to test the specified models and examine the nature of the relationship among the variables. Moderating effects were found for negative religious coping. Higher levels of negative religious coping strengthened an inverse relationship between acculturative stress and substance use. Results also indicated direct relationships between religious coping mechanisms and substance use. External and positive religious coping were inversely related to substance use. Negative religious coping was positively related to substance use. This study aims to contribute knowledge of how religious coping influence’s the adaptation process of recent Latino immigrants. Expanding scientific understanding as to the function and effect of these coping mechanisms could lead to enhanced culturally relevant approaches in service delivery among Latino populations. Furthermore this knowledge could inform research about specific cognitions and behaviors that need to be targeted in prevention and treatment programs with this population.
