Pain represents a significant source of morbidity, function loss, and decreased quality of life among people living with HIV. The present study examined the associations among pain, pain treatment, and ARV adherence among indigent, HIV-positive substance abusers. Participants were recruited via targeted sampling strategies, and completed a one-time computer-assisted personal interview. ANOVA and chi-square tests were used to analyze differences in demographics, health and psychological status, health behaviors, by pain and pain treatment status; a multivariate logistic regression model was constructed to examine the contribution of pain/treatment status to recent ARV adherence. Results indicated that those with untreated pain had lower odds of achieving gold-standard 95% ARV adherence as compared to the pain-free and treated pain groups; higher substance dependence symptoms were also associated with significantly lower odds of 95% ARV adherence. Findings suggest that pain management is critical to the health of people living with HIV, specifically those with high levels of co-morbid health and psychological problems. The prevalence of untreated pain was elevated among this group, and contributed to reduced ARV adherence. Providers of clinical care to disadvantaged HIV-positive patients should emphasize routine assessment and appropriate treatment of pain in order to provide comprehensive HIV care.

The cooccurrence of HIV and unintended pregnancy has prompted a body of work on dual protection, the simultaneous protection against HIV and unintended pregnancy. This study examines dual protection and dual methods as a risk-reduction strategy for women living with HIV. Data are from a cross-sectional sample of HIV-positive women attended in Specialized STI/AIDS Public Health Service Clinics in 13 municipalities from all five regions of Brazil 2003-2004 (N = 834). Descriptive techniques and logistic regression were used to examine dual protection among women living with HIV. We expand the definition of dual protection to include consistent condom use and reversible/irreversible contraceptive methods, we test the dual methods hypothesis that women who use dual methods will use condoms less consistently than women who use only condoms, and we identify predictors of dual protection. Dual protection is common in our sample. Women who use dual methods have lower odds of consistent condom use than women who only use condoms. Among dual method users, we find that women who use an irreversible method use condoms more consistently than women who use a reversible method. Women on ART and with an HIV-serodiscordant partner have greater odds of consistent condom use than their counterparts.

Background Syndemic HIV and unintended pregnancy is prevalent in Brazil, where 79% of female HIV cases occur in women of reproductive age and 55% of all pregnancies are unintended. Although increasing condom use to prevent HIV may decrease non-barrier contraception and increase unintended pregnancy, few studies focus on dual protection or dual methods (condoms with another modern contraceptive). Aim To describe the correlates of dual method use and consistent condom use in women of reproductive age in Brazil. Method Data are from the 2006 Pesquisa Nacional de Demografia e Saúde da Mulher e da Criança, a decennial nationally representative household survey of women of reproductive age in Brazil. Multivariate logistic regression models identify the socio-demographic, sexual debut, fertility and relationship factors associated with dual method use and consistent condom use. Results Two-thirds of contracepting women in Brazil used dual protection (40% exclusive condoms, 27% dual methods). Consistent condom use in the past year occurred among 61% of exclusive condom users and 27% of dual method users. Dual methods (vs exclusive condoms) was associated with some high school education [relative risk ratio (RRR)=1.69, p<0.05], living in the Southern region (RRR=1.59, p<0.01), and number of children (RRR=1.22, p<0.01), net of other factors. Consistent condom use was associated with condom use at sexual debut [adjusted odds ratio (AOR)=1.84, p<0.001], wants no (more) children (AOR=1.86, p<0.001), single/separated relationship status (AOR=2.77/2.45, p<0.001) and using exclusive condoms (vs dual methods: AOR=0.19, p<0.001). Conclusions Findings highlight that targeting and delivering integrated HIV and family planning services should focus on completed/large families. single/separated individuals, and promoting dual protection at sexual debut.

Abstract Syndemic Zika virus, HIV and unintended pregnancy call for an urgent understanding of dual method (condoms with another modern non-barrier contraceptive) and consistent condom use. Multinomial and logistic regression analysis using data from the Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher (PNDS), a nationally representative household survey of reproductive-aged women in Brazil, identified the socio-demographic, fertility and relationship context correlates of exclusive non-barrier contraception, dual method use and condom use consistency. Among women in marital and civil unions, half reported dual protection (30% condoms, 20% dual methods). In adjusted models, condom use was associated with older age and living in the northern region of Brazil or in urban areas, whereas dual method use (versus condom use) was associated with younger age, living in the southern region of Brazil, living in non-urban areas and relationship age homogamy. Among condom users, consistent condom use was associated with reporting Afro-religion or other religion, not wanting (more) children and using condoms only (versus dual methods). Findings highlight that integrated STI prevention and family planning services should target young married/in union women, couples not wanting (more) children and heterogamous relationships to increase dual method use and consistent condom use.

Early and sustained antiretroviral therapy (ART) adherence can suppress the HIV virus in individuals and reduce onward transmission of HIV in the population. Religiosity has been associated with better HIV clinical outcomes. Data are from a longitudinal, observational study of 749 HIV-infected individuals from Brazil, Zambia, and Thailand (HPTN 063). Ordered logistic regression assessed whether religious service attendance was associated with ART adherence (self-reported and plasma HIV-RNA) and moderated the association between alcohol problems and ART adherence. In each country, > 80% of participants reported high self-reported ART adherence (good/very good/excellent). Religious service attendance exceeded 85% but was statistically unrelated to adherence. In combined-country models, (p = 0.03) as alcohol problems increased, the probability of high self-reported ART adherence, as well as viral-load, became weaker at higher compared to low service attendance frequency. Future studies should evaluate spirituality variables and replicate the moderation analyses between religious attendance and alcohol problems.ResumenLa adherencia temprana y sostenida a la terapia antirretroviral (TAR) puede suprimir el virus del VIH en los individuos y reducir la transmisión del VIH en la población. La religiosidad se ha asociado con mejores resultados clínicos del VIH. Los datos provienen de un estudio observacional longitudinal de 749 individuos infectados con VIH de Brasil, Zambia y Tailandia (HPTN 063). La regresión logística ordenada evaluó si la asistencia al servicio religioso estaba asociada con la adherencia al TAR (autoreportado y el ARN del VIH en plasma) y moderaba la asociación entre los problemas del alcohol y la adherencia al TAR. En cada país, > 80% de los participantes reportaron un alto cumplimiento autoreportado de ART (bueno/muy bueno/excelente). La asistencia al servicio religioso excedió el 85%, pero estadísticamente no estuvo relacionada con la adherencia. En los modelos de países combinados, (p = 0.03) a medida que aumentaban los problemas de alcohol, la probabilidad de una alta adherencia autoreportada al TAR, así como la carga viral, se debilitó a una frecuencia de asistencia más alta en comparación con la baja. Los estudios futuros deberían evaluar las variables de espiritualidad y reproducir los análisis de moderación entre asistencia religiosa y problemas con el alcohol.

Masculine gender ideologies are thought to underlie alcohol use, intimate partner violence (IPV) perpetration, and sexual risk of HIV and other sexually transmitted infections (STIs). We extend on studies in the Indian context by examining the roles of masculine gender ideologies, alcohol use, and IPV on three outcomes of HIV risk (condom use, genital tract infection [GTI] symptoms, and GTI diagnosis). We applied logistic regression models to cross-sectional data of men and their wives in rural Maharashtra, India (n = 1,080 couples). We found that men with less masculine gender ideologies demonstrated greater odds of condom use (i.e., lower odds no condom use, odds ratio [OR] = 0.96, 95% confidence interval [CI] = [0.93, 0.98]). IPV perpetration was associated with increased odds of reporting ≥1 GTI symptom (adjusted OR [AOR] = 1.56, 95% CI = [1.07, 2.26]) and decreased GTI diagnosis (AOR = 0.28, 95% CI = [0.08, 0.97]). Moderate alcohol consumption was associated with increased odds of reporting ≥1 GTI symptom (AOR = 1.51, 95% CI = [1.01, 2.25]). Our findings have direct implications for men’s and women’s health in rural India, including targeted GTI diagnosis and treatment, integrated violence prevention in STI clinics, and targeted intervention on masculine gender ideologies.
