RESUMO

While multi-level theories and frameworks have become a cornerstone in broader efforts to address HIV inequities, little is known regarding their application in adolescent and young adult (AYA) HIV research. To address this gap, we conducted a scoping review to assess the use and application of multi-level theories and frameworks in AYA HIV prevention and care and treatment empirical research. We systematically searched five databases for articles published between 2010 and May 2020, screened abstracts, and reviewed eligible full-text articles for inclusion. Of the 5890 citations identified, 1706 underwent full-text review and 88 met the inclusion criteria: 70 focused on HIV prevention, with only 14 on care and treatment, 2 on both HIV prevention and care and treatment, and 2 on HIV-affected AYA. Most authors described the theory-based multi-level framework as informing their data analysis, with only 12 describing it as informing/guiding an intervention. More than seventy different multi-level theories were described, with 38% utilizing socio-ecological models or the eco-developmental theory. Findings were used to inform the adaptation of an AYA World Health Organization multi-level framework specifically to guide AYA HIV research.

RESUMO

Adolescent mental health (AMH) is a critical driver of HIV outcomes, but is often overlooked in HIV research and programming. The implementation science Exploration, Preparation, Implementation, Sustainment (EPIS) framework informed development of a questionnaire that was sent to a global alliance of adolescent HIV researchers, providers, and implementors working in sub-Saharan Africa with the aim to (1) describe current AMH outcomes incorporated into HIV research within the alliance; (2) identify determinants (barriers/gaps) of integrating AMH into HIV research and care; and (3) describe current AMH screening and referral systems in adolescent HIV programs in sub-Saharan Africa. Respondents reported on fourteen named studies that included AMH outcomes in HIV research. Barriers to AMH integration in HIV research and care programs were explored with suggested implementation science strategies to achieve the goal of integrated and sustained mental health services within adolescent HIV programs.

RESUMO

The COVID-19 pandemic and subsequent mitigation measures led to social disruption and negative economic shocks for a large proportion of Uganda's population. The social and economic consequences of COVID-19 on Ugandan men's sexual behaviours, including transactional sex relationships, are unclear. We conducted in-depth interviews between November 2021-February 2022 with 26 men in a high HIV prevalence region of Uganda. Data were analysed thematically to understand how sexual relationships, including transactional sex, were impacted by COVID-19. We found that COVID-19 mitigation measures had far-reaching social and economic impacts on most respondents, particularly those employed in the informal economy. Men described experiencing job loss, food insecurity and restricted mobility, which limited opportunities to provide for and meet with transactional sex partners. Inability to provide financial resources meant that men could not form new transactional sex relationships and men who could no longer provide for their existing transactional sex partners consistently reported relationship dissolution. Men who reported stable employment during the pandemic described few changes in transactional sex relationships. Similarly, men in non-transactional relationships did not report relationship dissolution despite decreased financial provision. Further research should assess the potential short- and long-term impacts of COVID-19 mitigation measures on transactional sex relationships.

RESUMO

Adolescents and young adults (AYA) 13-24 years old make up a disproportionate 21% of new HIV diagnoses. Unfortunately, they are less likely to treat HIV effectively, with only 30% achieving viral suppression, limiting efforts to interrupt HIV transmission. Previous work with mindfulness-based stress reduction (MBSR) has shown promise for improving treatment in AYA living with HIV (AYALH). This randomized controlled trial compared MBSR with general health education (HT). Seventy-four 13-24-year-old AYALH conducted baseline data collection and were randomized to nine sessions of MBSR or HT. Data were collected at baseline, post-program (3 months), 6 and 12 months on mindfulness and HIV management [medication adherence (MA), HIV viral load (HIV VL), and CD4]. Longitudinal analyses were conducted. The MBSR arm reported higher mindfulness at baseline. Participants were average 20.5 years old, 92% non-Hispanic Black, 51% male, 46% female, and 3% transgender. Post-program, MBSR participants had greater increases than HT in MA (p = 0.001) and decreased HIV VL (p = 0.052). MBSR participants showed decreased mindfulness at follow-up. Given the significant challenges related to HIV treatment in AYALH, these findings suggest that MBSR may play a role in improving HIV MA and decreasing HIV VL. Additional research is merited to investigate MBSR further for this important population.

RESUMO

Achieving the 95-95-95 UNAIDS targets requires meeting the needs of adolescents, however we lack evidenced-based approaches to improving adolescent adherence to antiretroviral therapy (ART), increasing viral suppression, and supporting general wellbeing. We developed Family Connections as a group intervention for adolescents and their adult caregivers and conducted a randomized controlled trial in Ndola, Zambia to test feasibility and acceptability. Fifty pairs (n = 100) of adolescents (15-19 years and on ART ≥ 6 months) and their caregivers were randomly assigned either to the intervention consisting of 10 group sessions over 6 months, or to a comparison group, which received the usual care. Each pair completed baseline and endline surveys, with adolescents also undergoing viral load testing. Of the 24-intervention adolescent/caregiver pairs, 88% attended at least eight group sessions. Most adolescents (96%) and all caregivers would recommend Family Connections to peers. Adolescent viral failure decreased but did not significantly differ by study group. Adolescents in the intervention group showed a greater reduction in HIV-related feelings of worthlessness and shame than the comparison group. The feasibility, acceptability, and the positive trend toward significantly reducing internalized stigma, generated by this Family Connections pilot study, contributes valuable data to support adolescent/caregiver approaches that use peer groups.

RESUMO

OBJECTIVE: How clinics structure the delivery of antiretroviral therapy (ART) services may influence patient adherence. We assessed the relationship between models of HIV care delivery and adherence as measured by medication possession ratio (MPR) among treatment-experienced adults in Tanzania, Uganda and Zambia. METHODS: Eighteen clinics were grouped into three models of HIV care. Model 1-Traditional and Model 2-Mixed represented task-sharing of clinical services between physicians and clinical officers, distinguished by whether nurses played a role in clinical care; in Model 3-Task-Shifted, clinical officers and nurses shared clinical responsibilities without physicians. We assessed MPR among 3,419 patients and calculated clinic-level MPR summaries. We then calculated the mean differences of percentages and adjusted residual ratio (aRR) of the association between models of care and incomplete adherence, defined as a MPR <90%, adjusting for individual-level characteristics. RESULTS: In the adjusted analysis, patients in Model 1-Traditional were more likely than patients in Model 2-Mixed to have MPR <90% (aRR = 1.60, 95% CI 1-2.48). Patients in Model 1-Traditional were no more likely than patients in Model 3-Task-Shifted to have a MPR <90% (aRR = 1.58, 95% 0.88-2.85). There was no evidence of differences in MPR <90% between Model 2-Mixed and Model 3-Task-Shifted (aRR = 0.99, 95% CI 0.59-1.66). CONCLUSION: Non-physician-led ART programmes were associated with adherence levels as good as or better than physician-led ART programmes. Additional research is needed to optimise models of care to support patients on lifelong treatment.

RESUMO

We examined the relationship between past-year violence victimization and viral load (VL) failure among consecutively-sampled male and female adolescents and young adults, aged 15-24, in four HIV clinics in Ndola, Zambia. Measures of past-year physical violence, psychological abuse, and forced sex were adapted from the ICAST-C and WHO Multi-Country Study. Using logistic regression, we derived associations between VL failure (≥ 1000 copies/mL) and: any victimization; cumulative victimization; and types and perpetrators of violence. Among 272 youth (59.2% female, 72.8% perinatally infected), 73.5% (n = 200) experienced past-year violence and 36.8% (n = 100) had VL failure. Higher odds of VL failure were observed for participants who reported high frequency of any violence versus no violence victimization (adjusted OR, aOR: 3.58; 95% CI 1.14-11.27), high frequency of psychological abuse versus no psychological abuse (aOR: 3.32; 95% CI 1.26-8.70), any versus no violence from a family member other than a parent/caregiver for physical violence (aOR: 2.18, 95% CI 1.05-4.54) and psychological abuse (aOR: 2.50; 95% CI 1.37-4.54), and any versus no physical violence from a friend/peer (aOR: 2.14, 95% CI 1.05-4.36). Past-year violence victimization was associated with VL failure when considering the frequency, type, and perpetrator of violence. Programs addressing violence among youth living with HIV may be critical to improving viral suppression and preventing onward transmission.

RESUMO

Little is known about adherence to antiretroviral therapy (ART) among adolescents in sub-Saharan Africa, where the majority of the world's HIV-positive adolescents reside. We assessed individual, household, and HIV self-management characteristics associated with a 48-hour treatment gap in the preceding 3 months, and a pharmacy medication possession ratio (MPR) that assessed the number of ART pills dispensed divided by the number of ART pills required in the past 6 months, among 285 Zambians, ages 15-19 years. Factors significantly associated with a 48-hour treatment gap were being male, not everyone at home being aware of the adolescent's HIV status, and alcohol use in the past month. Factors associated with an MPR < 90% included attending the clinic alone, alcohol use in the past month, and currently not being in school. Findings support programs to strengthen adolescents' HIV management skills with attention to alcohol use, family engagement, and the challenges adolescents face transitioning into adulthood, especially when they are no longer in school.

RESUMO

Research suggests a syndemic of substance use, mental illness, and familial conflict is associated with poor HIV medical outcomes among African American persons living with HIV (PLHIV). Social support may facilitate positive health outcomes. This study explores psychosocial correlates of HIV medical outcomes, defined as undetectable viral load (UVL) and acute care minimization. Data were from baseline of the BEACON study (N = 351). UVL was ≤40 copies/mL. Acute care minimization was defined as no ER visits and/or hospitalizations in 6 months. Descriptive statistics and Poisson regression were implemented (N = 351). Moderate syndemic burden was associated with viral suppression. Individuals with main partner caregivers had 35% higher likelihood of viral suppression than individuals whose main supporters were neither kin nor main partners (adjusted point-prevalence rate ratio [APR] = 1.35; 95% CI [1.05, 1.74]). Surprisingly, individuals with more health-related support were more likely to use acute care than individuals with less health-related support (p<.05). Interaction analyses showed that physical function modified the relationship between main supporter type and acute care minimization. Results suggest that social support receipt was not consistently associated with HIV medical outcomes. Conversely, higher syndemic burden may have facilitated positive outcomes through necessitating increased rates of health care engagement. Health care professionals should elicit discussion of social support to strengthen PLHIVs' and their supporters' relationships to improve their health. Results highlight the need for culturally tailored interventions to improve HIV medical outcomes among African American PLHIV substance users.

RESUMO

Informal care receipt is associated with health outcomes among people living with HIV. Less is known about how caregivers' own social support may affect their care recipient's health. We examined associations between network characteristics of informal caregivers and HIV viral suppression among former or current drug using care recipients. We analyzed data from 258 caregiver-recipient dyads from the Beacon study, of whom 89% of caregivers were African American and 59% were female. In adjusted logistic regression analysis, care recipients had lower odds of being virally suppressed if their caregiver was female, was caring for youth involved in the criminal justice system, and had network members who used illicit drugs. Caregivers' greater numbers of non-kin in their support network was positively associated with viral suppression among care recipients. The findings reveal contextual factors affecting ART outcomes and the need for interventions to support caregivers, especially HIV caregiving women with high-risk youth.

RESUMO

BACKGROUND: Organization of HIV care and treatment services, including clinic staffing and services, may shape clinical and financial outcomes, yet there has been little attempt to describe different models of HIV care in sub-Saharan Africa (SSA). Information about the relative benefits and drawbacks of different models could inform the scale-up of antiretroviral therapy (ART) and associated services in resource-limited settings (RLS), especially in light of expanded client populations with country adoption of WHO's test and treat recommendation. METHODS: We characterized task-shifting/task-sharing practices in 19 diverse ART clinics in Tanzania, Uganda, and Zambia and used cluster analysis to identify unique models of service provision. We ran descriptive statistics to explore how the clusters varied by environmental factors and programmatic characteristics. Finally, we employed the Delphi Method to make systematic use of expert opinions to ensure that the cluster variables were meaningful in the context of actual task-shifting of ART services in SSA. RESULTS: The cluster analysis identified three task-shifting/task-sharing models. The main differences across models were the availability of medical doctors, the scope of clinical responsibility assigned to nurses, and the use of lay health care workers. Patterns of healthcare staffing in HIV service delivery were associated with different environmental factors (e.g., health facility levels, urban vs. rural settings) and programme characteristics (e.g., community ART distribution or integrated tuberculosis treatment on-site). CONCLUSIONS: Understanding the relative advantages and disadvantages of different models of care can help national programmes adapt to increased client load, select optimal adherence strategies within decentralized models of care, and identify differentiated models of care for clients to meet the growing needs of long-term ART patients who require more complicated treatment management.

RESUMO

BACKGROUND: Contraception services can help meet the family planning goals of women living with HIV as well as prevent mother-to-child transmission. Due to antiretroviral therapy, survival has improved for people living with HIV, and more HIV-positive women may desire to have a child or another child. Behavioral interventions, involving counseling or education, can help women choose and use an appropriate contraceptive method. OBJECTIVES: We systematically reviewed studies of behavioral interventions for HIV-positive women intended to inform contraceptive choice, encourage contraceptive use, or promote adherence to a contraceptive regimen. SEARCH METHODS: Until 2 August 2016, we searched MEDLINE, CENTRAL, Web of Science, POPLINE, ClinicalTrials.gov and ICTRP. For the initial review, we examined reference lists and unpublished project reports, and we contacted investigators in the field. SELECTION CRITERIA: Studies evaluated a behavioral intervention for improving contraceptive use for family planning (FP). The comparison could have been another behavioral intervention, usual care, or no intervention. We also considered studies that compared HIV-positive versus HIV-negative women. We included non-randomized studies as well as randomized controlled trials (RCTs).Primary outcomes were pregnancy and contraception use, e.g. uptake of a new method or improved use or continuation of current method. Secondary outcomes were knowledge of contraceptive effectiveness and attitude about contraception or a specific contraceptive method. DATA COLLECTION AND ANALYSIS: Two authors independently extracted the data. One entered the data into RevMan and a second verified accuracy. We evaluated RCTs according to recommended principles. For non-randomized studies, we examined the quality of evidence using the Newcastle-Ottawa Quality Assessment Scale. Given the need to control for confounding factors in non-randomized studies, we used adjusted estimates from the models when available. Where we did not have adjusted analyses, we calculated the odds ratio (OR) with 95% confidence interval (CI). Due to varied study designs and interventions, we did not conduct meta-analysis. MAIN RESULTS: With three new reports, 10 studies from seven African countries met our eligibility criteria. Eight non-randomized studies included 8980 participants. Two cluster RCTs had 7136 participants across 36 sites. Three studies compared a special FP intervention versus usual care, three examined FP services integrated with HIV services, and four compared outcomes for HIV-positive and HIV-negative women.In four studies with high or moderate quality evidence, the special intervention was associated with contraceptive use or pregnancy. A study from Nigeria compared enhanced versus basic FP services. All sites had integrated FP and HIV services. Women with enhanced services were more likely to use a modern contraceptive method versus women with basic services (OR 2.48, 95% CI 1.31 to 4.72). A cluster RCT conducted in Kenya compared integrated FP and HIV services versus standard referral to a separate FP clinic. Women with integrated services were more likely to use more effective contraception (adjusted OR 1.81, 95% CI 1.24 to 2.63). Another cluster RCT compared an HIV prevention and FP intervention versus usual care in Kenya, Namibia, and Tanzania. Women at the special intervention sites in Tanzania were more likely to use highly effective contraception (adjusted OR 2.25, 95% CI 1.24 to 4.10). They were less likely to report unprotected sex (no condom use) at last intercourse (adjusted OR 0.23, 95% CI 0.14 to 0.40). Across the three countries, women at the special intervention sites were less likely to report any unprotected sex in the past two weeks (adjusted OR 0.56, 95% CI 0.32 to 0.99). A study in Côte d'Ivoire integrated HIV and FP services. HIV-positive women had a lower incidence of undesired pregnancy, but not overall pregnancy, compared with HIV-negative women (1.07 versus 2.38; reported P = 0.023). AUTHORS' CONCLUSIONS: The studies since 2009 focused on using modern or more effective methods of contraception. In those later reports, training on FP methods and counseling was more common, which may strengthen the intervention and improve the ability to meet clients' needs. The quality of evidence was moderate from the more recent studies and low for those from the 1990s.Comparative research involving contraceptive counseling for HIV-positive women is limited. The FP field needs better ways to help women choose an appropriate contraceptive and continue using that method. Improved counseling methods are especially needed for limited resource settings, such as clinics focusing on people living with HIV.

RESUMO

Equitable access to antiretroviral therapy (ART) for men and women with human immunodeficiency virus (HIV) infection is a principle endorsed by most countries and funding bodies, including the U.S. President's Emergency Plan for AIDS (acquired immunodeficiency syndrome) Relief (PEPFAR) (1). To evaluate gender equity in ART access among adults (defined for this report as persons aged ≥15 years), 765,087 adult ART patient medical records from 12 countries in five geographic regions* were analyzed to estimate the ratio of women to men among new ART enrollees for each calendar year during 2002-2013. This annual ratio was compared with estimates from the Joint United Nations Programme on HIV/AIDS (UNAIDS)(†) of the ratio of HIV-infected adult women to men in the general population. In all 10 African countries and Haiti, the most recent estimates of the ratio of adult women to men among new ART enrollees significantly exceeded the UNAIDS estimates for the female-to-male ratio among HIV-infected adults by 23%-83%. In six African countries and Haiti, the ratio of women to men among new adult ART enrollees increased more sharply over time than the estimated UNAIDS female-to-male ratio among adults with HIV in the general population. Increased ART coverage among men is needed to decrease their morbidity and mortality and to reduce HIV incidence among their sexual partners. Reaching more men with HIV testing and linkage-to-care services and adoption of test-and-treat ART eligibility guidelines (i.e., regular testing of adults, and offering treatment to all infected persons with ART, regardless of CD4 cell test results) could reduce gender inequity in ART coverage.

RESUMO

To explore the role of informal caregivers in adherence, we compared adherence reports by caregivers to those of care recipients. We identified individual-level and relationship factors associated with agreement between caregivers' reports of recipients' adherence and assessed viral suppression. Participants were care recipients, who were on ART and had ever injected drugs, and their caregivers (N = 258 dyads). Nearly three-fourths of caregivers' reports of recipients' ART adherence agreed with recipients' viral suppression status. Agreement was associated with recipient age and expressing affection or gratitude to the caregiver, caregiver's having been close to someone who died of HIV/AIDS, and caregiver's fear of caregiving-related HIV (re)infection, while it was negatively associated with recipient's limited physical functioning. Our findings support the utility of caregiver proxy reports of care recipients' ART adherence and suggest ways to identify and promote HIV caregiver attention to and support of this vulnerable population's ART adherence.

RESUMO

OBJECTIVES: We assessed retention and predictors of attrition (recorded death or loss to follow-up) in antiretroviral treatment (ART) clinics in Tanzania, Uganda and Zambia. METHODS: We conducted a retrospective cohort study among adults (≥18 years) starting ART during 2003-2010. We purposefully selected six health facilities per country and randomly selected 250 patients from each facility. Patients who visited clinics at least once during the 90 days before data abstraction were defined as retained. Data on individual and programme level risk factors for attrition were obtained through chart review and clinic manager interviews. Kaplan-Meier curves for retention across sites were created. Predictors of attrition were assessed using a multivariable Cox-proportional hazards model, adjusted for site-level clustering. RESULTS: From 17 facilities, 4147 patients were included. Retention ranged from 52.0% to 96.2% at 1 year to 25.8%-90.4% at 4 years. Multivariable analysis of ART initiation characteristics found the following independent risk factors for attrition: younger age [adjusted hazard ratio (aHR) and 95% confidence interval (95%CI) = 1.30 (1.14-1.47)], WHO stage 4 ([aHR (95% CI): 1.56 (1.29-1.88)], >10% bodyweight loss [aHR (95%CI) = 1.17 (1.00-1.38)], poor functional status [ambulatory aHR (95%CI) = 1.29 (1.09-1.54); bedridden aHR1.54 (1.15-2.07)], and increasing years of clinic operation prior to ART initiation in government facilities [aHR (95%CI) = 1.17 (1.10-1.23)]. Patients with higher CD4 cell count were less likely to experience attrition [aHR (95%CI) = 0.88 (0.78-1.00)] for every log (tenfold) increase. Sites offering community ART dispensing [aHR (95%CI) = 0.55 (0.30-1.01) for women; 0.40 (0.21-0.75) for men] had significantly less attrition. CONCLUSIONS: Patient retention to an individual programme worsened over time especially among males, younger persons and those with poor clinical indicators. Community ART drug dispensing programmes could improve retention.

RESUMO

Although scale-up of antiretroviral therapy (ART) since 2005 has contributed to declines of about 30% in the global annual number of human immunodeficiency (HIV)-related deaths and declines in global HIV incidence, estimated annual HIV-related deaths among adolescents have increased by about 50% and estimated adolescent HIV incidence has been relatively stable. In 2012, an estimated 2,500 (40%) of all 6,300 daily new HIV infections occurred among persons aged 15-24 years. Difficulty enrolling adolescents and young adults in ART and high rates of loss to follow-up (LTFU) after ART initiation might be contributing to mortality and HIV incidence in this age group, but data are limited. To evaluate age-related ART retention challenges, data from retrospective cohort studies conducted in seven African countries among 16,421 patients, aged ≥15 years at enrollment, who initiated ART during 2004-2012 were analyzed. ART enrollment and outcome data were compared among three groups defined by age at enrollment: adolescents and young adults (aged 15-24 years), middle-aged adults (aged 25-49 years), and older adults (aged ≥50 years). Enrollees aged 15-24 years were predominantly female (81%-92%), commonly pregnant (3%-32% of females), unmarried (54%-73%), and, in four countries with employment data, unemployed (53%-86%). In comparison, older adults were more likely to be male (p<0.001), employed (p<0.001), and married, (p<0.05 in five countries). Compared with older adults, adolescents and young adults had higher LTFU rates in all seven countries, reaching statistical significance in three countries in crude and multivariable analyses. Evidence-based interventions to reduce LTFU for adolescent and young adult ART enrollees could help reduce mortality and HIV incidence in this age group.

RESUMO

The Evidence Project conducts systematic reviews and meta-analyses of HIV behavioral interventions, behavioral aspects of biomedical interventions, combination prevention strategies, modes of service delivery, and integrated programs in low- and middle-income countries. Here, we present the overall protocol for our reviews. For each topic, we conduct a comprehensive search of five online databases, complemented by secondary reference searching. Articles are included if they are published in peer-reviewed journals and present pre/post or multi-arm data on outcomes of interest. Data are extracted from each included article by two trained coders working independently using standardized coding forms, with differences resolved by consensus. Risk of bias is assessed with the Evidence Project tool. Data are synthesized descriptively, and meta-analysis is conducted when there are similarly measured outcomes across studies. For over 20 years, this approach has allowed us to synthesize literature on the effectiveness of interventions and contribute to the global HIV response.

RESUMO

BACKGROUND: Contraception services can help meet the family planning goals of women living with HIV as well as prevent mother-to-child transmission. Due to the increased availability of antiretroviral therapy, survival has improved for people living with HIV, and more HIV-positive women may desire to have a child or another child. This review examines behavioral interventions to improve contraceptive use, for family planning, among women who are HIV-positive. OBJECTIVES: We systematically reviewed studies that examined behavioral interventions for HIV-positive women that were intended to inform contraceptive choice, encourage contraceptive use, or promote adherence to a contraceptive regimen. SEARCH METHODS: Through October 2012, we searched MEDLINE, CENTRAL, POPLINE, EMBASE, CINAHL, PsycINFO, ClinicalTrials.gov and ICTRP. For other relevant papers, we examined reference lists and unpublished project reports, and contacted investigators in the field. SELECTION CRITERIA: Studies evaluated a behavioral intervention for improving contraceptive use for contraception. The comparison could be another behavioral intervention, usual care, or no intervention. We also considered studies that compared HIV-positive women versus HIV-negative women. We included nonrandomized (observational) studies as well as randomized trials.Primary outcomes were pregnancy and contraception use, e.g., uptake of a new method, improved use or continuation of current method. Secondary outcomes were knowledge of contraceptive effectiveness and attitude about contraception in general or about a specific contraceptive method. DATA COLLECTION AND ANALYSIS: Two authors independently extracted the data. One author entered the data into RevMan and a second verified accuracy. We examined the quality of evidence using the Newcastle-Ottawa Quality Assessment Scale.Given the need to control for confounding factors in observational studies, we used adjusted estimates from the models when available. Where we did not have adjusted analyses, we calculated the odds ratio (OR) with 95% confidence interval (CI). Due to varied study designs, we did not conduct meta-analysis. MAIN RESULTS: The seven studies meeting our inclusion criteria had a total of 8882 women. All were conducted in Africa. Three studies compared a special intervention versus standard services. In one, the special intervention site showed greater use of non-condom contraceptives per visit (OR 6.40; 95% CI 5.37 to 7.62) and reported a lower pregnancy incidence. In another study, use of modern contraceptives was more likely for women at sites with enhanced versus basic integrated services (OR 2.48; 95% CI 1.31 to 4.72), but the groups did not differ significantly in change from baseline. In the third study, new use of modern contraceptives, excluding condoms, was less likely for women with integrated services versus those with routine care (OR 0.56; 95% CI 0.42 to 0.75), but new use of condoms was more likely (OR 1.73; 95% CI 1.52 to 1.98).Four older studies compared HIV-positive women versus HIV-negative women. None showed any significant difference between the HIV-status groups in use of modern contraceptives. Two did not provide an intervention for the HIV-negative women. In the larger of the two studies, HIV-positive women were less likely to become pregnant (OR 0.55; 95% CI 0.43 to 0.69). HIV-positive women were more likely to discontinue their hormonal contraceptive (OR 2.52; 95% CI 1.53 to 4.14) but more likely to use condoms (OR 2.82; 95% CI 2.18 to 3.65) and spermicide (OR 2.36; 95% CI 1.69 to 3.30). Two studies provided the intervention to both HIV-status groups. One included many of the women from the study just mentioned, and also showed fewer pregnancies for HIV-positive women (OR 0.39; 95% CI 0.23 to 0.68). In the other study, the HIV-status groups were not significantly different for pregnancy or consistent condom use. AUTHORS' CONCLUSIONS: Comparative research on contraceptive counseling for HIV-positive women has been limited. We found little innovation in the behavioral interventions. Our ability to make statements about overall results is hampered by varied study designs, interventions, and outcome assessments. The quality of evidence was moderate. Since some of these studies were conducted, improvements in HIV treatment have influenced the fertility intentions of HIV-positive people.The family planning field needs better ways to help women choose an appropriate contraceptive and continue using that chosen method. Women with HIV may have special concerns regarding family planning. Research could focus on assessing the woman's needs and training providers to address those issues rather than delivering standardized information.

RESUMO

BACKGROUND: Despite efforts to promote HIV counseling and testing (HCT) among couples, few couples know their own or their partners' HIV status. We assessed trends in HCT uptake among married individuals in Rakai district, southwestern Uganda. METHODS: We analysed data for 11,268 married individuals aged 15-49 years who were enrolled into the Rakai Community Cohort Study (RCCS) between 2003 and 2009. Married individuals were interviewed separately but were retrospectively linked to their partners at analysis. All participants had serologic samples obtained for HIV testing, and had the option of receiving HCT together (couples' HCT) or separately (individual HCT). Individuals were categorized as concordant HIV-positive if both partners had HIV; concordant HIV-negative if both did not have HIV; or HIV-discordant if only one of the partners had HIV. We used χ2 tests to assess linear trends in individual and couples' HCT uptake in the entire sample and conducted multinomial logistic regression on a sub-sample of 10,712 individuals to assess relative risk ratios (RRR) and 95% Confidence Intervals (95% CI) associated with individual and couples' HCT uptake. Analysis was done using STATA version 11.0. RESULTS: Uptake of couples' HCT was 27.2% in 2003/04, 25.1% in 2005/06, 28.5% in 2006/08 and 27.8% in 2008/09 (χ2 for trend = 2.38; P = 0.12). Uptake of individual HCT was 57.9% in 2003/04, 60.2% in 2005/06, 54.0% in 2006/08 and 54.4% in 2008/09 (χ2 for trend = 8.72; P = 0.003). The proportion of couples who had never tested increased from 14.9% in 2003/04 to 17.8% in 2008/09 (χ2 for trend = 18.16; P < 0.0001). Uptake of couples' HCT was significantly associated with prior HCT (Adjusted [Adj.] RRR = 6.80; 95% CI: 5.44, 8.51) and being 25-34 years of age (Adj. RRR = 1.81; 95% CI: 1.32, 2.50). Uptake of individual HCT was significantly associated with prior HCT (Adj. RRR = 6.26; 95% CI: 4.24, 9.24) and the female partner being HIV-positive (Adj. RRR = 2.46; 95% CI: 1.26, 4.80). CONCLUSION: Uptake of couples' HCT remained consistently low (below 30%) over the years, while uptake of individual HCT declined over time. These findings call for innovative strategies to increase demand for couples' HCT, particularly among younger couples and those with no prior HCT.
