Prevalence and associated risk factors of violence against conflict–affected female adolescents: a multi–country, cross–sectional study

Background Over half of displaced civilians in humanitarian emergencies are children, and these settings pose unique threats to children’s safety with long–lasting consequences. Our study broadens the limited evidence on violence against adolescent girls in emergencies by estimating prevalence and predictors of violence among adolescent girls aged 13–14 in South Kivu, Democratic Republic of the Congo (DRC), and aged 13–19 in refugee camps in the Benishangul–Gumuz region of Ethiopia. Methods Survey data were collected from a sample of 1296 adolescent girls using Computer–Assisted Personal Interview and Audio Computer–Assisted Self–Interview programming. Predictors of violence were modeled using multivariable logistic regression. Results The majority of adolescent girls (51.62%) reported experiencing at least one form of violence victimization in the previous 12 months: 31.78% reported being hit or beaten, 36.79% reported being screamed at loudly or aggressively, and 26.67% experienced unwanted sexual touching, forced sex, and/or sexual coercion. Across both countries, ever having a boyfriend and living with an intimate partner were strong predictors of violence. Fewer years of education completed in DRC, and young age in Ethiopia, were also associated with reported victimization. Conclusions Prevalence of violence against adolescent girls is high in these two conflict–affected contexts. Findings indicate a need for programs targeting younger populations, broader efforts to address different forms of victimization, and increased recognition of intimate partners and caregivers as perpetrators of violence in conflict–affected settings.

Sexual practices, partner concurrency and high rates of sexually transmissible infections among male sex workers in three cities in Vietnam

UNLABELLED Background This paper examines sexual practices, partner concurrency and sexually transmissible infections (STI)/HIV infection among male sex workers (MSWs) in Vietnam. METHODS Six hundred and fifty-four MSWs, aged 16-35 years, were recruited in Hanoi, Nha Trang and Ho Chi Minh City between 2009 and 2011. Survey measures included demographic characteristics, drug use, types of sexual partners and sexual practices. Subjects were screened for STIs, including HIV. RESULTS MSWs in Ho Chi Minh City (33%) were more likely than those from the other two sites to be current users of one or more types of illegal drugs (P<0.001). MSWs with both male and female elective partners (compared with other partnership types) were more likely to have anal sex with male client partners (P<0.001), elective male partners (P=0.045) and elective female partners (P=0.025). At last sex with a male client partner, only 30% used a condom during anal intercourse. At last sex with an elective female partner, only 31% used a condom during vaginal sex and only 3% during anal sex. Although rates of HIV are low (4%), other STIs are high, including chlamydia (17%), gonorrhoea (29%) and human papillomavirus (33%). Most (57.3%) have never been tested for HIV and only 17% have ever disclosed to a healthcare provider that they have sex with men. CONCLUSIONS Complex patterns of sexual concurrency, coupled with high rates of STIs, signal the urgent need for health services interventions among MSWs, both to improve individual health outcomes and to reduce secondary STI/HIV transmission among sexual partner networks.

Prevalence and behavioral correlates of depression and anxiety among male sex workers in Vietnam

ABSTRACT. Objectives: This study assessed depression and anxiety symptoms and their association with high-risk sexual and drug behaviors among male sex workers in 3 Vietnamese cities. Methods: Male sex workers ages 16 to 35 years old completed an interview that included the Center for Epidemiological Studies Depression Scale to assess depressive symptoms and the Beck Anxiety Inventory to assess anxiety symptoms, as well as questions assessing drug and sexual risk practices. Results: A majority of participants reported depressive symptomatology, although fewer reported symptoms of anxiety. Risky sexual and drug use practices predicted both types of symptoms. Conclusions: Mental distress is associated with drug and sexual risk among male sex workers.

Sexually transmissible infection and HIV prevention and treatment for young male sex workers in Vietnam: findings from the SHEATH intervention.

Background Urban centres in Vietnam have high rates of HIV infection, especially among men who have sex with men (MSM). A subgroup of MSM, young male sex workers (YMSW), are at especially high risk due to concurrent sex with multiple male and female partners, low levels of knowledge regarding HIV and sexually transmissible infection (STI) transmission, and limited engagement with health services, including STI and HIV screening and treatment. METHODS A targeted intervention (SHEATH) derived from Harm Reduction and Sexual Health Promotion intervention technology was implemented in an out-of-treatment population of YMSW in Hanoi and Ho Chi Minh City (n=919). RESULTS YMSW reported high levels of satisfaction with each of the seven core modules within the intervention and for the intervention as a whole. The intervention conferred significant benefit in relation to improved knowledge of STI and HIV transmission (P<0.001). Although only 36% of participants had seen a healthcare provider in the past year, following the intervention 81% intended to see one in the next 6 months. Similarly, although 71% of participants did not disclose that they were MSM the last time they visited a healthcare provider, following the intervention 71% intended to do so at their next visit. High rates of STIs (>10%) and HIV (9.5%) were also found. CONCLUSION The data show that the SHEATH intervention can be implemented in this population and setting, is met with high rates of acceptability, and positively impacts STI and HIV knowledge and multiple health services outcomes (including knowledge of HIV status and disposition towards habituation of HIV screening).

High rates of oral STIs among male sex workers in Vietnam

Male sex workers (MSW) in Vietnam have complex sexual partner profiles, including both male and female client partners and both male and female elective partners. Although sex practices vary across partner types, both active and receptive oral sex is common with all partner types. As a consequence of this complexity, MSWs are at high risk for becoming infected with oral STIs as well as for transmitting STIs to sex partners. Between 2009 and 2011, a community sample of MSWs, age 16–35 years, was recruited for …

The effect of gender norms on the association between violence and hope among girls in the Democratic Republic of the Congo

Background. Girls at early stages of adolescence are vulnerable to violence victimization in humanitarian contexts, but few studies examine factors that affect girls’ hope in these settings. We assessed attitudes toward traditional gender norms as an effect modifier of the relationship between violence exposure and future orientation in displaced girls. Methods. Secondary analysis, using multivariable regression of cross-sectional data from girls ages 10–14 in South Kivu, Democratic Republic of the Congo. Key variables of interest were attitudes toward intimate partner violence (IPV), Childrens Hope Scale (CHS) score, and exposure to physical, emotional, and sexual violence within the last 12 months. Additional covariates included age, educational status, and territory. Results. The interaction of exposure to violence and attitudes toward IPV magnified the association between violence exposure and lower CHS score for physical violence (β = −0.09, p = 0.040) and unwanted sexual touching (β = −0.20, p = 0.003) among girls age 10–14, when adjusting for other covariates. The interaction of exposure to violence and attitudes toward IPV magnified the association between violence exposure and lower CHS score for forced sex (β = −0.22, p = 0.016) among girls age 13–14, when adjusting for covariates. Findings for emotional violence, any form of sexual violence, and coerced sex trended toward lower CHS scores for girls who reported higher acceptance of IPV, but did not reach significance. Conclusions. Findings support the utility of gender norms-transformative programming in increasing resilience of girls who have experienced sexual violence in humanitarian contexts.

Injection and sexual risk practices among young heroin users in Hanoi Vietnam.

Abstract Epidemiological data in Vietnam shows high HIV prevalence rates among injection drug users, especially in urban centres. However, there are limited data on specific practices used to prepare and inject drugs or on sexual practices among Vietnamese injectors. A street-based cross-sectional interview was conducted with 862 heroin injectors in Hanoi, Vietnam, to collect such data. Variability was seen in both injection and sexual risk, with 12.9% of current injectors reporting at least one unsafe method of drug sharing and 57.1% reporting unsafe sex in the past 30 days. These risks were strongly associated with those who engaged in unsafe injection significantly more likely to engage in unsafe sex (69.4% vs. 55.3%) and those engaging in unsafe sex significantly more likely to engage in unsafe injection (15.7% vs. 9.2%). These findings highlight the overlap of injection and sexual risk practices among Vietnamese heroin users and suggest the need for strong, broadly targeted HIV prevention activities among this population.

HIV and other STIs in male sex workers: Findings from a sexual health promotion intervention in Vietnam

Male sex workers (MSWs) in Vietnam are at high risk for acquisition and transmission of human immunodeficiency virus (HIV) and other sexually transmitted infections (STIs), yet are extremely disengaged from the healthcare system. This contributes to large numbers of untreated or late-treated infections and increased secondary transmission. We enrolled 995 MSWs in Hanoi and Ho Chi Minh City (HCMC) in a Sexual Health Promotion intervention that included face-to-face delivery of seven content modules, a clinical examination and testing for HIV, syphilis, gonorrhea and Chlamydia. Onsite treatment was provided for STIs, and those who tested positive for HIV were referred to local treatment centers. While 64.6% of participants had never been to a health service and fewer than half (41.2%) had ever been tested for HIV, 67.1% returned for test results. This testing identified 109 (11.0%) participants who were HIV-positive and 312 (31.4%) who tested positive for at least one other STI. Substantive differences were seen in MSWs from different cities, with those from Hanoi more likely to have ever visited a health service (57.8% vs. 24.9%) and to have taken a prior HIV test (54.1% vs. 37.9%) than those in HCMC. Sexual health promotion is a promising approach to engaging MSWs in health services.

The school participation effect: investigating violence and formal education among girls in the Democratic Republic of the Congo

Abstract Little is known about the differential experiences with violence among girls in conflict-affected societies based on their involvement in formal education. A quantitative survey was conducted with girls between the ages of 10–14 across 14 sites in South Kivu, Democratic Republic of the Congo. The prevalence of three forms of violence was estimated across four levels of participation in formal education, and multivariable mixed effects logistic regression models were used to compare girls’ increasing levels of education to those who reported never attending school. Trend tests across the four levels of education were conducted for violence outcomes. Girls’ higher levels of participation in formal education were significantly associated with lower reported rates of physical and sexual violence. Findings suggest a significant protective effect of formal education on girls from physical and sexual violence. Findings also suggest a significant relationship between girls’ age and risk of experiencing physical and sexual violence.

Using a population-based survey approach to estimate child separation after a natural disaster: findings from post-Hurricane Haiti

Introduction This study explores findings of a population-based approach to measure the prevalence of unaccompanied and separated children (UASC) during the Hurricane Matthew aftermath in Haiti. Methods We conducted a cross-sectional survey using two-stage cluster sampling. Participants were asked to provide information on their own household composition, as well as the household composition of their closest neighbour (the Neighborhood Method). The study took place between February and March 2017 in Haiti’s Sud Department, a region severely affected by Hurricane Matthew in October 2016. 1044 primary respondents provided information about their own household, and 4165 people in the household of their closet neighbour. The primary outcome measured was the prevalence of UASC in the Sud Department following Hurricane Matthew. Secondary outcomes of interest included the characteristics of these children, including age, sex, reason for separation and current caregiver. Results Of the 2046 children currently living in the surveyed households, 3.03% (95% CI 2.29% to 3.77%) were reported to have been separated from their normal caregiver during Hurricane Matthew. Among these 62 children, 9 were unaccompanied, and there were slightly more boys than girls (56% vs 44%, p=0.37). Of the 2060 children who lived in surveyed households when the hurricane hit, 1.12% (95% CI 0.67% to 1.57%) had since departed without their caregiver. The prevalence of separation reported for neighbours’ households was not significantly different from that in respondents’ households (p values between 0.08 and 0.29). Conclusions This study is the first known attempt to measure the prevalence of child separation following a natural disaster. Overall, the rates of separation were relatively low. Similarities between primary and secondary reports of child separation via the Neighborhood Method indicate that this may be a viable approach to measuring UASC in certain contexts.
