Associations Between Neighborhood Characteristics,Social Cohesion,and Perceived Sex Partner Risk and Non-Monogamy Among HIV-Seropositive and HIV-Seronegative Women in the Southern U.S.

Neighborhood social and physical factors shape sexual network characteristics in HIV-seronegative adults in the U.S. This multilevel analysis evaluated whether these relationships also exist in a predominantly HIV-seropositive cohort of women. This cross-sectional multilevel analysis included data from 734 women enrolled in the Women’s Interagency HIV Study’s sites in the U.S. South. Census tract-level contextual data captured socioeconomic disadvantage (e.g., tract poverty), number of alcohol outlets, and number of non-profits in the census tracts where women lived; participant-level data, including perceived neighborhood cohesion, were gathered via survey. We used hierarchical generalized linear models to evaluate relationships between tract characteristics and two outcomes: perceived main sex partner risk level (e.g., partner substance use) and perceived main sex partner non-monogamy. We tested whether these relationships varied by women’s HIV status. Greater tract-level socioeconomic disadvantage was associated with greater sex partner risk (OR 1.29, 95% CI 1.06–1.58) among HIV-seropositive women and less partner non-monogamy among HIV-seronegative women (OR 0.69, 95% CI 0.51–0.92). Perceived neighborhood trust and cohesion was associated with lower partner risk (OR 0.83, 95% CI 0.69–1.00) for HIV-seropositive and HIV-seronegative women. The tract-level number of alcohol outlets and non-profits were not associated with partner risk characteristics. Neighborhood characteristics are associated with perceived sex partner risk and non-monogamy among women in the South; these relationships vary by HIV status. Future studies should examine causal relationships and explore the pathways through which neighborhoods influence partner selection and risk characteristics.     

Temporal Trends in Population Level Impacts of Risk Factors for Sexually Transmitted Infections Among Men Who Have Sex with Men,Heterosexual Men,and Women: Disparities by Sexual Identity (1998–2013)

Sexually transmitted infections (STIs) remain a significant public health problem worldwide. We aimed to describe the temporal trends and relative contributions of established risk factors to STIs among sexual health center attendees. This retrospective study included more than 90,000 individuals who attended a sexual health center in Sydney, Australia, during the period 1998–2013. Multivariable logistic regression models were used to identify the correlates of STI diagnoses for three groups: men who have sex with men (MSM), heterosexual men, and women separately. Trends in population attributable risk percentages (PAR%) were estimated to assess the relative contributions of the risk factors on STI diagnosis. STI diagnosis rates among sexual health clinic attendees increased by 75% from 16 to 28% among MSM and more than doubled among heterosexual men and women (7–15 and 5–12%, respectively). Inconsistent condom use, three or more sex partners, sex overseas, past STI diagnosis, and contact with an STI case collectively contributed 61, 74 and 55% of the STI diagnoses among MSM, heterosexual men and women, respectively. Increase in STI diagnosis associated with temporal trends in combined risk factors including condomless sex, multiple sex partners, past STI diagnosis, and contact with an STI case. Although the majority of the factors considered in this study have been significantly associated with STI positivity in all three groups, their overall population level contributions to the epidemic have changed substantially. Our results indicated significant disparities between the MSM and heterosexual men and women as well as sex-specific differences in terms of sexual behaviors.     

An Ongoing Burden: Chlamydial Infections among Young American Indian Women

Objectives Studies conducted in the 1980s, when there was limited chlamydia screening, showed high positivity, 23%–30%, among American Indian women. In the 1990s, chlamydia screening and treatment programs were implemented in a variety of settings serving American Indian women including Indian Health Service (IHS) clinics. Yet, a 2000–2001 national survey documented a chlamydia prevalence of 13.3% among young American Indian women, five times higher than the prevalence among whites. The purpose of this analysis was to determine the chlamydia positivity and risk factors for chlamydia among women screened in Indian Health Service (IHS) clinics participating in the National Infertility Prevention Program in 2003. Methods Data were analyzed from 11,485 chlamydia tests performed among women universally screened in 23 IHS clinics in three states (Montana, North Dakota, South Dakota). Sexual risk history and clinical data were collected in the Montana IHS clinics and used to assess risk factors for chlamydial infection in a multivariate logistic regression model. Results Chlamydia positivity was highest among 15–19 year old women screened in IHS clinics (state range: 15.3%–18.6%). Positivity decreased with age but remained high even among women aged 30–34 years. Young age and having had multiple or new sex partners in the last 90 days were associated with an increased risk of chlamydia; however, chlamydia positivity was greater than 6.7% for women with no known risk factors. Conclusions A greater emphasis on chlamydia screening and treatment should be a component of any program whose goal is to improve the reproductive health of American Indian women.

     

Dual Use of Condoms With Other Contraceptive Methods Among Adolescents and Young Women in the United States

PurposeTo estimate the prevalence of and factors associated with dual method use (i.e., condom with hormonal contraception or an intrauterine device) among adolescents and young women in the United States.MethodsWe used 2006–2010 National Survey of Family Growth data from 2,093 unmarried females aged 15–24 years and at risk for unintended pregnancy. Using multivariable logistic regression, we estimated adjusted odds ratios (aORs) and 95% confidence intervals (CIs) to assess the associations between dual method use at last sex and sociodemographic, behavioral, reproductive history, and sexual behavior factors.ResultsAt last sex, 20.7% of adolescents and young women used dual methods, 34.4% used condoms alone, 29.1% used hormonal contraception or an intrauterine device alone, and 15.8% used another method or no method. Factors associated with decreased odds of dual method use versus dual method nonuse included having a previous pregnancy (aOR = .44, 95% CI .27–.69), not having health insurance coverage over the past 12 months (aOR = .41, 95% CI .19–.91), and having sex prior to age 16 (aOR = .49, 95% CI .30–.78).ConclusionsThe prevalence of dual method use is low among adolescents and young women. Adolescents and young women who may have a higher risk of pregnancy and sexually transmitted infections (e.g., those with a previous pregnancy) were less likely to use dual methods at last sex. Interventions are needed to increase the correct and consistent use of dual methods among adolescents and young women who may be at greater risk for unintended pregnancy and sexually transmitted infections.     

The role of material deprivation and consumerism in the decisions to engage in transactional sex among young people in the urban slums of Blantyre,Malawi

Transactional sex has been associated with a high risk of HIV acquisition and unintended pregnancy among young women in urban slums in sub-Saharan Africa. However, few studies have explored the structural drivers of transactional sex from the perspective of both genders in these settings. This paper explores how young men and women understand the factors that lead to transactional sex among their peers, and how deprivation of material resources (housing, food and health care access) and consumerism (a desire for fashionable goods) may instigate transactional sex in the urban slums of Blantyre, Malawi. Data from 5 focus group discussions and 12 in-depth interviews undertaken with a total of 60 young men and women aged 18–23 years old, conducted between December 2012 and May 2013, were analysed using anticipated and grounded codes. Housing and food deprivation influenced decisions to engage in transactional sex for both young men and women. Poor health care access and a desire for fashionable goods (such as the latest hair or clothing styles and cellular phones) influenced the decisions of young women that led to transactional sex. Interventions that engage with deprivations and consumerism are essential to reducing sexual and reproductive health risks in urban slums.

Factors associated with HIV testing among male motorbike taxi drivers in urban Vietnam

Using the Attitude-Skills-Knowledge (ASK) model, this study examined the prevalence of, and factors associated with, human immunodeficiency virus (HIV) testing among male motorbike taxi drivers (MMTDs). In a cross-sectional design, using quantitative approaches, 291 MMTDs were recruited from 135 sites across 13 districts in Hanoi, Vietnam, for a face-to-face interview. Applying the ASK model modified as a central theory, logistic regression was used to identify determinants of HIV testing. Although many MMTDs engaged in multiple risk behaviours for HIV, only 20.6% had been tested for HIV during the past 12 months. The tested model included one factor of the ASK model, HIV prevention knowledge (adjusted odds ratio [AOR] = 4.76; 95% confidence interval [CI] = 2.12–10.7) and five additional factors: being married (AOR = 3.13; 95% CI = 1.25–4.78), preferring sex with men or with both men and women (AOR = 8.72; 95% CI = 1.48–51.5), having lower number of lifetime sex partners (AOR = 0.66; 95% CI = 0.49–0.88), higher number of past year sex partners (AOR = 2.97: 95% CI = 1.21–7.31) and discussing condom use when having sex with partners (AOR = 0.08; 95% CI = 0.01–7.31). This modified ASK model provided better fit than the ASK model, as it explained more variance in HIV testing (47 vs. 29.8%). Recognising factors associated with HIV testing among MMTDs enables us to create suitable public health intervention strategies.     

Interpersonal and structural contexts of intimate partner violence among female sex workers in conflict-affected northern Uganda

Intimate partner violence (IPV) is the most prevalent form of violence against women, yet remains under-researched among sex workers in sub-Saharan Africa. We explored the interpersonal and structural determinants of recent IPV among female sex workers in northern Uganda. This analysis drew on data from a community-based cross-sectional study (conducted May 2011–January 2012), involving 379 female sex workers in Gulu, northern Uganda. Using logistic regression and multivariable modeling, we examined the correlates of recent male-perpetrated physical or sexual IPV. Of 379 women with noncommercial partners, 59 percent reported having experienced recent moderate/severe physical or sexual IPV. Reporting recent client violence (adjusted odds ratio (AOR): 3.67; 95 percent confidence interval [CI]: 2.31–5.83), doing what their partner wanted (AOR: 2.46; 95 percent CI: 1.46–4.13), and forced sexual debut (AOR: 1.92; 95 percent CI: 1.20–3.05) were independently associated with moderate/severe IPV; recent police arrest and/or incarceration were/was marginally significantly associated with IPV (AOR: 2.25; 95 percent CI: 0.86–5.88, p = 0.097). Greater odds of IPV among sex workers were associated with recent workplace violence, forced sexual debut, and gendered power dynamics favoring male partner control. Programs and policies promoting the safety and health of marginalized women and addressing gender dynamics and violence are needed.     

Generational sex work and HIV risk among Indigenous women in a street-based urban Canadian setting

In Canada, Indigenous women are over-represented among new HIV infections and street-based sex workers. Scholars suggest that Aboriginal women's HIV risk stems from intergenerational effects of colonisation and racial policies. This research examined generational sex work involvement among Aboriginal and non-Aboriginal women and the effect on risk for HIV acquisition. The sample included 225 women in street-based sex work and enrolled in a community-based prospective cohort, in partnership with local sex work and Aboriginal community partners. Bivariate and multivariate logistic regression modeled an independent relationship between Aboriginal ancestry and generational sex work and the impact of generational sex work on HIV infection among Aboriginal sex workers. Aboriginal women (48%) were more likely to be HIV-positive, with 34% living with HIV compared to 24% non-Aboriginal women. In multivariate logistic regression model, Aboriginal women remained three times more likely to experience generational sex work (AOR:2.97; 95%CI:1.5,5.8). Generational sex work was significantly associated with HIV (AOR = 3.01, 95%CI: 1.67–4.58) in a confounder model restricted to Aboriginal women. High prevalence of generational sex work among Aboriginal women and three-fold increased risk for HIV infection are concerning. Policy reforms and community-based, culturally safe and trauma informed HIV-prevention initiatives are required for Indigenous sex workers.

A syndemic of psychosocial and mental health problems in Liberia: Examining the link to transactional sex among young pregnant women

ABSTRACT

Transactional sex may be a driver of the rising HIV epidemic in Liberia, especially among young women. The goal of this study was to explore the independent and additive effects of psychosocial conditions on engagement in transactional sex among 191 pregnant women in Monrovia, Liberia. Between March and August 2016, women receiving prenatal services completed a cross-sectional structured questionnaire. These data were used to examine the independent and additive effects of exposure to trauma, depression, post-traumatic stress disorder symptoms, and intimate partner violence on transactional sex. Overall, the results are in support of our hypothesis that these psychosocial conditions cluster together and are independently associated with transactional sex. Multivariate logistic regression analysis demonstrated an additive effect of the number of psychosocial conditions experienced on transactional sex. Women experiencing 2 psychosocial conditions had 5.96 greater odds of engaging in transactional sex compared to women reporting 0 conditions (AOR: 5.96, 95% CI: 2.22–15.99), and women experiencing 3 or 4 psychosocial conditions had 11.91 greater odds of engaging in transactional sex compared to women report 0 conditions (AOR: 11.91, 95% CI: 4.12–34.45). Our results demonstrate the need for comprehensive HIV prevention programming inclusive of mental health support and IPV prevention for Liberian women.     

Factors Associated with Event Level Anal Sex and Condom Use During Anal Sex Among Adolescent Women

PurposeTo examine the distribution of and factors associated with event-level heterosexual anal sex and of event-level condom use during anal sex among adolescent women.MethodsAdolescent women (N = 387; age 14–17 years at enrollment) were recruited from primary care clinics for a longitudinal cohort study of sexually transmitted infections and sexual behavior. Data were taken from daily sexual diaries; generalized estimating equation logistic regression assessed the likelihood of anal sex or condom use during anal sex on a given day.ResultsHeterosexual anal intercourse is a small but nonrandom event-level component in adolescent women's sexual behavior. About 30% of anal sex events were condom protected. Mood, partner, and situational factors predicted anal sex, but not condom use during anal sex; within-day and recent behavior factors were the strongest influences on both outcomes.ConclusionsOur findings suggest the importance of providers' screening adolescent women patients during office visits about anal sex and about condom use during anal sex, as well as asking questions about the context of these behaviors to appropriately tailor risk reduction counseling.     

Age-specific factors related to institutional delivery in Nigeria: Insights from the 2011 Multiple Indicator Cluster Survey

With 814 maternal deaths per 100,000 live births, maternal mortality remains a significant public health problem in Nigeria. We examined associations between maternal age and institutional delivery among 9,485 women, using data from the 2011 Nigeria Multiple Indicator Cluster Survey. We used multiple logistic regression to identify enabling factors and barriers to institutional delivery. Older maternal age was positively associated with institutional delivery. In age-stratified, adjusted analyses, secondary/higher education and living in wealthy households were consistently associated with increased odds of institutional delivery among the youngest (15–19 years) and the oldest (40–49 years) women. Higher parity was associated with significantly reduced odds of institutional delivery among women <40 years, but was not associated among women aged 40–49 years. Among women of 40–49 years, attending at least four antenatal care (ANC) visits was associated with increased odds of institutional delivery; among women of ages 15–19 years, the association was not significant. Similarly, having a skilled ANC provider was not significantly associated with institutional delivery among women aged 15–19 and 40–49 years. These findings suggest that women at the highest risk for maternal death may face barriers to institutional delivery services. Focused policies and programs are needed to address women’s reproductive health vulnerabilities.     

Prevalence of Masturbation and Associated Factors in a British National Probability Survey

A stratified probability sample survey of the British general population, aged 16 to 44 years, was conducted from 1999 to 2001 (N = 11,161) using face-to-face interviewing and computer-assisted self-interviewing. We used these data to estimate the population prevalence of masturbation, and to identify sociodemographic, sexual behavioral, and attitudinal factors associated with reporting this behavior. Seventy-three percent of men and 36.8% of women reported masturbating in the 4 weeks prior to interview (95% confidence interval 71.5%–74.4% and 35.4%–38.2%, respectively). A number of sociodemographic and behavioral factors were associated with reporting masturbation. Among both men and women, reporting masturbation increased with higher levels of education and social class and was more common among those reporting sexual function problems. For women, masturbation was more likely among those who reported more frequent vaginal sex in the last four weeks, a greater repertoire of sexual activity (such as reporting oral and anal sex), and more sexual partners in the last year. In contrast, the prevalence of masturbation was lower among men reporting more frequent vaginal sex. Both men and women reporting same-sex partner(s) were significantly more likely to report masturbation. Masturbation is a common sexual practice with significant variations in reporting between men and women.     

Sexual Violence Towards Married Women in Bangladesh

This article explored the magnitude and nature of within marriage sexual violence against women and factors associated with physically forced sex by husbands in urban and rural Bangladesh using population-based survey data from 2001 (n = 2,702). Results showed high prevalence of lifetime sexual violence: 37 % in urban and 50 % in rural areas. An overwhelming majority of the women reported being sexually abused by husbands more than once. Logistic regression analyses revealed that six out of ten independent variables included in the models were significant. The factors positively associated with physically forced sex by husbands during the last 12 months were: history of physical abuse of husband’s mother by his father; level of controlling behavior by husband; and forced or coerced first sex. Women’s age (20–24 compared to 15–19) and dowry demand at marriage increased the likelihood of this violence in the rural area. Urban women in the second and third income quartiles were more likely to be exposed to this violence compared to women in the first quartile. Results highlight the need for prevention programs targeting men, which would help at the same time to break the cycle of intergenerational exposure and thereby transmission of violence. Notions of gender equality; women’s sexual rights; and women’s right to consent and choice need to be widely promoted particularly among men.     

Reproductive Health and Sexual Violence Among Urban American Indian and Alaska Native Young Women: Select Findings from the National Survey of Family Growth (2002)

Existing data on American Indians and Alaska Natives (AI/ANs) has indicated high rates of unintended pregnancy, high-risk sexual behavior, and experiences of sexual violence. This study from the first analysis to examine AI/ANs and the urban AI/AN subgroup in the National Survey of Family Growth (NSFG) reports new findings of reproductive health and sexual violence among urban AI/AN young women. We examined 2002 NSFG data on urban AI/AN women ages 15–24 years for pregnancies/births, unintended pregnancy, sexual initiation and contraceptive use. We also examined non-voluntary first sexual intercourse among urban AI/AN women ages 18–44 years. Prevalence estimates and 95 % confidence intervals were calculated. Findings include prevalence rates of risk factors among urban AI/AN women ages 15–24 years including unprotected first sex (38 %), first sex with much older partners (36 %), three or more pregnancies (13 %) and births (5 %) and unintended pregnancies (26 %). Seventeen percent of urban AI/ANs ages 18–44 years reported experiencing non-voluntary first sex. Sixty-one percent of urban AI/AN women ages 15–24 years were not using any method of contraception. Current contraceptive methods among those using a method included: injections/implants (23 %), contraceptive pills (32 %) and condoms (25 %). Findings describe reproductive health risk factors among young urban AI/AN women and highlight the need for enhanced surveillance on these issues. Those working to improve AI/AN health need these data to guide programming and identify resources for implementing and evaluating strategies that address risk factors for this overlooked population.     

Factors associated with forced sex among women accessing health services in rural Haiti: implications for the prevention of HIV infection and other sexually transmitted diseases

The goals of the current study were to: (1) estimate the prevalence of forced sex among women accessing services at a women's health clinic in rural Haiti; and (2) examine factors associated with forced sex in this population. Based on data from a case-control study of risk factors for sexually transmitted diseases (STDs), a cross-sectional analysis to examine factors associated with forced sex was performed. A number of factors related to gender inequality/socioeconomic vulnerability placed women in rural Haiti at higher risk of forced sex. The strongest factors associated with forced sex in multivariate analyses were: age, length of time in a relationship, occupation of the woman's partner, STD-related symptoms, and factors demonstrating economic vulnerability. The findings suggest that prevention efforts must go beyond provision of information and education to the pursuit of broader initiatives at both local and national levels. At the community level, policy-makers should consider advancing economic opportunities for women who are vulnerable to forced sex. Improving access to community-based income-generating activities may begin to address this problem. However, the viability of these local projects depends largely upon Haiti's 'macro-economic' situation. In order to ensure the success of local initiatives, external humanitarian and development assistance to Haiti should be supported. By broadening the definition of "prevention" interventions, we may begin to address the systemic problems that contribute to the occurrence of forced sex and the increasing incidence of HIV infection throughout the world, such as gender inequality and economic vulnerability. Taking into account factors influencing risk at the local level as well as the macro-level will potentially improve our capacity to reduce the risk of forced sex and the spread of STDs, including HIV infection, for millions of women living in poverty worldwide.     

Changes in the Timing of Sexual Initiation Among Young Muslim and Christian Women in Nigeria

Sexual initiation during adolescence has important demographic and health consequences for a population, yet no systematic analysis of changes in the timing of sexual initiation has been conducted in Nigeria. Two rounds of national surveys conducted in 1990 and 2003 were used to examine changes in the timing of sexual initiation among female adolescents in Nigeria. Multivariate survival analysis using Cox proportional hazards models was used to assess changes in the risk of sexual initiation and to identify the correlates of first sex. Contrary to what has been reported in several Nigerian studies, there was no decline in age at first sex among Christian adolescents. Age at first sex did not change significantly for Christian adolescents, although premarital sex appears to have increased–primarily due to an increase in the age at marriage. Age at first sex did increase among Muslim women. Premarital sex remained low among Muslim women. A number of socioeconomic variables were associated with the timing of sexual initiation. Weekly exposure to the mass media was associated with earlier sexual initiation. The degree to which an environment was liberal or restrictive was a key determinant of the timing of sexual initiation in Nigeria. The findings also illustrate the important role of socioeconomic factors in determining the timing of sexual initiation in Nigeria. As secondary education increases in Northern Nigeria, additional increases in the age at sexual debut are likely among Muslim women. The study raises concerns about the influence of the mass media on the timing of first sex in Nigeria. The evidence of an absence of changes in the timing of sexual initiation among Christian women in more than a decade implies that programs which aim to delay the timing of sexual initiation in Southern Nigeria may have limited success. With age at marriage already high among Christian women, programs that focus on abstinence until marriage may also be pursuing an approach with limited chances of success.     

Discontinuation of oral contraceptives and depot medroxyprogesterone acetate among women with and without HIV in Uganda, Zimbabwe and Thailand

BackgroundWe examined hormonal contraceptive (HC) discontinuation and factors associated with discontinuation among HIV-uninfected women and the effect of HIV diagnosis on subsequent contraceptive use.Study DesignWe analyzed 4461 HIV-uninfected women from a prospective study of HC and HIV acquisition in Uganda, Zimbabwe and Thailand. Participants were ages 18–35 years, not pregnant, and using oral contraceptives (OCs) or injectable depot medroxyprogesterone acetate (DMPA) for at least 3 months before enrollment (median duration of OC and DMPA use before enrollment was 11.7 and 8.9 months, respectively). We compared the probability of OC and DMPA discontinuation using survival analysis and factors related to discontinuation using Cox regression. We also analyzed contraceptive patterns among 194 women who became infected with HIV.ResultsMedian duration of use after study enrollment was 15.6 months for OCs and 18.5 months for DMPA. Continuation rates for both methods were highest in Thailand. Factors associated with OC discontinuation included, nausea, breast tenderness, condom use, and no sex. Factors associated with DMPA discontinuation included young age, breast tenderness, nausea, irregular bleeding, high-risk sexual behaviors, partner risk, condom use, and no sex. Following an HIV diagnosis, 135 (98.5%) of 137 hormonal users continued HC and 14 (25%) of 57 nonusers began using HC.ConclusionsContraceptive continuation for OCs and DMPA was relatively high over 2 years. Young women, those reporting side effects, and those using condoms are more likely to discontinue and need ongoing contraceptive counseling. Many women receiving HIV-positive diagnoses desire effective contraception.     

Human papillomavirus type 18/16 infection and prevalence among middle-aged and older Chinese rural women: a cross-sectional survey in Wufeng,Hubei Province

This study aimed to measure the prevalence and potential factors related to HPV 16/18 infection among middle-aged and older Chinese rural women. The study was conducted among women aged 35–65 years in rural villages within Wufeng in Hubei Province. Data were collected using a pretested questionnaire between July and August 2015. Cervical specimens were collected for HPV DNA detection and typing by using careHPV. Pearson’s Chi-square and logistic regression analyses were used to examine associations with HPV positivity. Among 1001 participants, the prevalence of HPV 18/16 positive genotyping was 15.88% (n = 159). Husbands’ extramarital sex (adjusted odds ratio [OR] = 15.85, 95% confidence interval [CI] 5.76–43.59), cervicitis (adjusted OR = 9.27, 95% CI 5.06–16.99), condom usage (adjusted OR = 0.16, 95% CI 0.05–0.53), higher average number of live births (adjusted OR = 1.98, 95% CI 1.32–2.96 for two live births; adjusted OR = 3.29, 95% CI 1.39–7.81 for three or more live births) were associated with HPV infection. The prevalence of HPV infection among participating women from rural areas was higher than that in several other areas in China. Our findings can aid efforts to prevent HPV infection to lower the risk of cervical cancer.
