RESUMEN

BACKGROUND: Mobile Health ("mHealth") interventions have shown promise in improving HIV treatment outcomes for stigmatized populations. This paper presents the findings from a randomized controlled trial to assess the efficacy, participant-level feasibility and acceptability of a theory-informed mHealth intervention, Motivation Matters!, designed to improve viral suppression and ART adherence among HIV-seropositive women who engage in sex work in Mombasa, Kenya. METHODS: A total of 119 women were randomized between the intervention and standard of care control. The primary outcome examined viral suppression (≤ 30 copies/mL) six months following ART initiation. ART adherence was assessed monthly using a visual analogue scale. Participant-level feasibility was measured through response rates to study text messages. Acceptability was assessed through qualitative exit interviews. RESULTS: Six months following treatment initiation, 69% of intervention and 63% of control participants were virally suppressed (Risk Ratio [RR] = 1.09, 95% Confidence Interval [95% CI] (0.83, 1.44). Among women who were viremic at baseline and endorsed engagement in sex work, 74% of women in the intervention arm compared with 46% of women in the control arm achieved viral suppression at month six RR = 1.61, 95% CI (1.02, 2.55). Adherence was higher in intervention versus control participants every month. All participants responded to at least one message, and there was a 55% overall response rate to intervention text messages. Qualitative exit interviews suggested high acceptability and perceived impact of the intervention. CONCLUSION: The improvements in ART adherence and viral suppression, combined with encouraging data on feasibility and acceptability, provides preliminary evidence that Motivation Matters! could support ART adherence and viral suppression in women who engage in sex work. TRIAL REGISTRATION: This trial was registered with ClinicalTrials.gov (NCT02627365, 10/12/2015; http://clinicaltrials.gov ).

RESUMEN

BACKGROUND: In Kenya, harm reduction organizations have adopted evidence-based peer educator (PE) programs, where former people who inject drugs (PWID) serve as community health liaisons to engage PWID in HIV, HCV and harm reduction services. While PEs play an integral role in healthcare delivery, little data exists on their roles, risks and experiences working with PWID, which may be used to inform local harm reduction policy. METHODS: PE's from two harm reduction sites in Nairobi were randomly and purposively selected to participate in semi-structured in-depth interviews. Thematic analysis was conducted to characterize the expected versus actual roles that PEs employ while serving PWID, personal motivation and/or challenges and occupational health risks. Data was analyzed using Atlas.ti software. RESULTS: Twenty PEs participated in the study. On average, PEs were 37 years of age, with 3 years of service. Female representation was 30%. Expected responsibilities included locating clients, establishing rapport, educating and escorting clients to addiction care facilities. Additional roles included attending to clients outside of work hours, escorting clients to medical appointments and facilitating patient-provider discussions. Occupational health risks included harassment by police and drug dealers, needle sticks, and close proximity to drug use environments that could prompt drug relapse. Despite these challenges and risks, PEs are motivated by their personal experiences of overcoming addiction with help from harm reduction programs. CONCLUSIONS/RECOMMENDATIONS: PEs play a vital role in HIV, HCV and harm reduction service delivery in Kenya, often exceeding their job descriptions by offering additional support to PWID. Recommendations include (1) advocating for PEs to provide patient navigation services, (2) promoting the use of post-exposure prophylaxis (PEP), (3) providing occupational mental health services to prevent drug relapse, and (4) collaborating with law enforcement to address harassment, with the ultimate goal of reducing HIV and HCV incidence among PWID.

RESUMEN

Background: Active case finding (ACF) for tuberculosis (TB) is a key strategy to reduce diagnostic delays, expedite treatment, and prevent transmission. Objective: Our objective was to identify the populations, settings, screening and diagnostic approaches that optimize coverage (proportion of those targeted who were screened) and yield (proportion of those screened who had active TB) in ACF programs. Methods: We performed a comprehensive search to identify studies published from 1980-2016 that reported the coverage and yield of different ACF approaches. For each outcome, we conducted meta-analyses of single proportions to produce estimates across studies, followed by meta-regression to identify predictors. Findings. Of 3,972 publications identified, 224 met criteria after full-text review. Most individuals who were targeted successfully completed screening, for a pooled coverage estimate of 93.5%. The pooled yield of active TB across studies was 3.2%. Settings with the highest yield were internally-displaced persons camps (15.6%) and healthcare facilities (6.9%). When compared to symptom screening as the reference standard, studies that screened individuals regardless of symptoms using microscopy, culture, or GeneXpert®MTB/RIF (Xpert) had 3.7% higher case yield. In particular, microbiological screening (usually microscopy) as the initial test, followed by culture or Xpert for diagnosis had 3.6% higher yield than symptom screening followed by microscopy for diagnosis. In a model adjusted for use of Xpert testing, approaches targeting persons living with HIV (PLWH) had a 4.9% higher yield than those targeting the general population. In all models, studies targeting children had higher yield (4.8%-5.7%) than those targeting adults. Conclusion: ACF activities can be implemented successfully in various populations and settings. Screening yield was highest in internally-displaced person and healthcare settings, and among PLWH and children. In high-prevalence settings, ACF approaches that screen individuals with laboratory tests regardless of symptoms have higher yield than approaches focused on symptomatic individuals.

RESUMEN

The relationships between depressive symptoms, viral suppression, and condomless sex were examined in a prospective cohort study of 369 HIV-positive Kenyan female sex workers. Participants were screened for depressive symptoms at baseline and every six months until completion of the study (up to 66 months). HIV viral load (VL) was measured every six months and prostate specific antigen (PSA) testing in vaginal secretions was performed quarterly. Mild or greater depressive symptoms were found in 100 (27.1%) women and were associated with increased risk of detectable VL (aRR 1.41, 95%CI 0.97-2.07, p-value = 0.07), but were not associated with detectable PSA. The co-occurrence of PSA detection and detectable VL at the same visit suggests the potential for HIV transmission but was uncommon (2.4% of visits). The prevalence of depressive symptoms and the association with detectable VL suggests the need for screening and treatment of depression for comprehensive HIV care in this population.

RESUMEN

Nurses have an integral role to play in achieving the 95-95-95 goals to stem the HIV epidemic. We used the Information-Motivation-Behavioral Skills (IMB) theoretical model to develop a nurse-delivered, mHealth intervention to support antiretroviral therapy adherence among female sex workers living with HIV in Mombasa, Kenya. Twenty-three purposively sampled female sex workers living with HIV participated in 5 focus group discussions to iteratively develop the message content as well as the format and structure of the nurse-delivered, text-based intervention. Focus group discussion interview guides were developed in accordance with the IMB model. Transcripts were analyzed according to IMB themes, and findings were used to develop the intervention. Information-oriented texts addressed concerns and misconceptions; motivation-oriented texts reinforced women's desires to feel healthy enough to engage in activities; and behavioral skills-oriented texts included strategies to remember medication doses. The nurse-delivered, theory-based, culturally tailored intervention to support medication adherence was evaluated.

RESUMEN

OBJECTIVES: Female sex workers (FSWs) in sub-Saharan Africa are a key population for HIV prevention and treatment interventions, but less attention is given to their family planning needs. We evaluated the prevalence and predictors of unmet contraceptive need in HIV-positive FSWs. STUDY DESIGN: This cross-sectional analysis used data from an existing longitudinal study of FSWs in Mombasa, Kenya. This analysis included women who were HIV positive, age ≥18 years, pre-menopausal, not currently pregnant or desiring pregnancy, and reported exchanging sex for cash or in-kind payment at the time of enrollment. Unmet contraceptive need was defined as non-use of modern non-barrier contraceptives and not currently trying to become pregnant. Poisson regression was used to identify factors independently associated with unmet contraceptive need. RESULTS: Among 346 HIV-positive FSWs, 125 (36.1%) reported modern non-barrier contraceptive use, leaving 221 (63.9%, 95%CI 58.8-68.9%) with unmet contraceptive need. Condom use was the only form of contraception for 129 (37.3%) participants. In unadjusted analyses, unmet contraceptive need was associated with physical abuse in the past year by someone other than a regular partner (PR 1.2, 95%CI 1.0-1.5), desire for (more) children (PR 1.3, 95%CI 1.1-1.5), and having 2-3 previous pregnancies compared to 0-1 prior pregnancies (PR 0.8, 95%CI 0.6-0.9). In adjusted analyses, lower number of previous pregnancies and having desire for future children remained significantly associated with a higher prevalence of unmet contraceptive need. CONCLUSIONS: Unmet need for modern non-barrier contraception was found in two-thirds of HIV-positive FSWs who reported that they were not currently trying to become pregnant, and was higher in women with the lowest number of prior pregnancies (0-1 prior pregnancies) and in those reporting desire for (more) children in the future. These findings highlight the need for concerted efforts to identify and eliminate barriers to contraceptive use in FSWs living with HIV.

RESUMEN

OBJECTIVES: Self-collection of genital specimens for high-risk types of human papillomavirus (hrHPV) detection may increase cervical cancer screening uptake. We hypothesized that women would prefer self-collection to clinician-collection of genital specimens. To test this hypothesis, and women's preference between two different self-collection approaches, a total of 199 women were enrolled in a cross-sectional study in Mombasa, Kenya. MATERIALS AND METHODS: Participants provided self-collected specimens using the Evalyn cytobrush (Rovers) stored in a dry tube and the Viba cytobrush (Rovers) stored in wet Aptima media (Hologic). A clinician also collected cervical specimens for hrHPV testing and for cytology, and performed visual inspection using acetic acid. A post-examination questionnaire assessed preferences for the different methods of specimen collection. To test the difference in proportions for each collection method, we performed an exact binomial probability test, under the null hypothesis that women would prefer each specimen-collection method equally. RESULTS: Most women preferred clinician-collection over self-collection (68% versus 32%, p < 0.01). For self-collection, dry-self collection with the Evalyn brush was preferred over the wet-selection with the Viba brush (53% versus 27%, p < 0.01). There was no association between preference for self-collection and preference for a particular self-collection cytobrush. CONCLUSION: Further research to understand and address obstacles to self-collection of genital specimens may be needed to improve the uptake of self-collection for cervical cancer screening, especially in settings with poor access to trained healthcare providers.

RESUMEN

Gender-based violence (GBV) is common among female sex workers (FSWs) and is associated with multiple HIV risk factors, including poor mental health, high-risk sexual behavior, and sexually transmitted infections (STIs). Prior studies have focused on GBV of one type (e.g. physical or sexual) or from one kind of perpetrator (e.g., clients or regular partners), but many FSWs experience overlapping types of violence from multiple perpetrators, with varying frequency and severity. We examined the association between lifetime patterns of GBV and HIV risk factors in 283 FSWs in Mombasa, Kenya. Patterns of GBV were identified with latent class analysis based on physical, sexual, or emotional violence from multiple perpetrators. Cross-sectional outcomes included depressive symptoms, post-traumatic stress disorder (PTSD) symptoms, disordered alcohol and other drug use, number of sex partners, self-reported unprotected sex, prostate-specific antigen (PSA) in vaginal secretions, and a combined unprotected sex indicator based on self-report or PSA detection. We also measured HIV/STI incidence over 12 months following GBV assessment. Associations between GBV patterns and each outcome were modeled separately using linear regression for mental health outcomes and Poisson regression for sexual risk outcomes. Lifetime prevalence of GBV was 87%. We identified 4 GBV patterns, labeled Low (21% prevalence), Sexual (23%), Physical/Moderate Emotional (18%), and Severe (39%). Compared to women with Low GBV, those with Severe GBV had higher scores for depressive symptoms, PTSD symptoms, and disordered alcohol use, and had more sex partners. Women with Sexual GBV had higher scores for disordered alcohol use than women with Low GBV, but similar sexual risk behavior. Women with Physical/Moderate Emotional GBV had more sex partners and a higher prevalence of unprotected sex than women with Low GBV, but no differences in mental health. HIV/STI incidence did not differ significantly by GBV pattern. The prevalence of GBV was extremely high in this sample of Kenyan FSWs, and different GBV patterns were associated with distinct mental health and sexual risk outcomes. Increased understanding of how health consequences vary by GBV type and severity could lead to more effective programs to reduce HIV risk in this vulnerable population.

RESUMEN

BACKGROUND: Female sex workers (FSWs) are at high risk for gender-based violence (GBV) and HIV infection. This study aimed to identify associations between GBV exposure in the past 12 months and biomarkers of physiologic stress and inflammation that may play a role in increased HIV risk among Kenyan FSWs. MATERIALS AND METHODS: Participating women responded to a detailed questionnaire on GBV and mental health. Plasma was collected for assessment of systemic C-reactive protein (CRP) and interleukin-6 (IL-6) levels. Hair proximal to the scalp was collected to measure cortisol concentration. CRP and IL-6 were measured by enzyme-linked immunosorbent assay, and hair cortisol concentration was determined by enzyme immunoassay. Log-transformed biomarker values were compared across GBV exposure categories using Kruskal-Wallis or Wilcoxon rank sum tests. Multivariable linear regression was used to explore associations between recent GBV and hair cortisol concentration. RESULTS: Two hundred eighty-three women enrolled, of whom 112 (39.6%) reported physical, sexual, or emotional violence in the past 12 months, 134 (47.3%) reported more remote exposure, and 37 (13.1%) reported no exposure. CRP and IL-6 levels did not differ across groups (p = 0.57 and p = 0.62, respectively). Among 141 women who provided hair, cortisol concentrations were higher among recently exposed women compared to the other two groups combined (p = 0.02). In multivariable regression, recently exposed women had higher hair cortisol levels than remotely exposed or unexposed women (adjusted beta = 0.52, 95% confidence interval 0.02-1.02, p = 0.04). CONCLUSIONS: While CRP and IL-6 levels did not differ by GBV category, recent GBV was associated with increased hair cortisol concentration. GBV-related increases in cortisol could affect health outcomes and merit study in relation to HIV acquisition risk.

RESUMEN

BACKGROUND: Little is known about fertility desire in HIV-positive female sex workers. Fertility desire could increase HIV transmission risk if it was associated with condomless sex or lower adherence to antiretroviral therapy. METHODS: A prospective cohort study was conducted among 255 HIV-positive female sex workers in Mombasa, Kenya. Using generalized estimating equations, fertility desire was evaluated as a risk factor for semen detection in vaginal secretions by prostate-specific antigen (PSA) test, a biomarker of condomless sex, detectable plasma viral load (VL), and HIV transmission potential, defined as visits with positive PSA and detectable VL. RESULTS: The effect of fertility desire on PSA detection varied significantly by nonbarrier contraception use (P-interaction < 0.01). At visits when women reported not using nonbarrier contraception, fertility desire was associated with higher risk of semen detection [82/385, 21.3% vs. 158/1007, 15.7%; adjusted relative risk (aRR) 1.58, 95% confidence interval (CI): 1.12 to 2.23]. However, when women used nonbarrier contraception, fertility desire was associated with lower risk of PSA detection (10/77, 13.0% vs. 121/536, 22.6%; aRR 0.58, 95% CI: 0.35 to 0.94). Fertility desire was not associated with detectable VL (31/219, 14.2% vs. 128/776, 16.5%; aRR 0.82, 95% CI: 0.46 to 1.45) or higher absolute risk of transmission potential (10/218, 4.6% vs. 21/769, 2.7%; adjusted risk difference = 0.011, 95% CI -0.031 to 0.050). CONCLUSIONS: Fertility desire was associated with higher risk of biological evidence of semen exposure when women were not using nonbarrier contraceptives. Low HIV transmission potential regardless of fertility desire suggests that the combination of condoms and antiretroviral therapy adherence was effective.

RESUMEN

BACKGROUND: As access to antiretroviral therapy in sub-Saharan Africa continues to expand, more women with HIV can expect to survive through their reproductive years. Modern contraceptives can help women choose the timing and spacing of childbearing. However, concerns remain that women with HIV who use non-barrier forms of modern contraception may engage in more condomless sex because of their decreased risk of unintended pregnancy. We examined whether non-barrier modern contraceptive use by HIV-positive female sex workers was associated with increased frequency of recent condomless sex, measured by detection of prostate-specific antigen (PSA) in vaginal secretions. METHODS: Women who were HIV-positive and reported transactional sex were included in this analysis. Pregnant and post-menopausal follow-up time was excluded, as were visits at which women reported trying to get pregnant. At enrollment and quarterly follow-up visits, a pelvic speculum examination with collection of vaginal secretions was conducted for detection of PSA. In addition, women completed a structured face-to-face interview about their current contraceptive methods and sexual risk behavior at enrollment and monthly follow-up visits. Log-binomial generalized estimating equations regression was used to test for associations between non-barrier modern contraceptive use and detection of PSA in vaginal secretions and self-reported condomless sex. Data from October 2012 through September 2014 were included in this analysis. RESULTS: Overall, 314 women contributed 1,583 quarterly examination visits. There was minimal difference in PSA detection at contraceptive-exposed versus contraceptive-unexposed visits (adjusted relative risk [aRR] 1.28, 95% confidence interval [95% CI] 0.93-1.76). There was a higher rate of self-reported condomless sex at visits where women reported using modern contraceptives, but this difference was not statistically significant after adjustment for potential confounding factors (aRR 1.59, 95% CI 0.98-2.58). CONCLUSION: Non-barrier methods of modern contraception were not associated with increased risk of objective evidence of condomless sex.

RESUMEN

INTRODUCTION: As adolescents and young women become sexually active, they are at risk of adverse reproductive health outcomes including sexually transmitted infections (STIs). We assessed feasibility and acceptability of STI screening among 15- to 24-year-old women in Mombasa, Kenya. METHODS: After sensitization activities, participants were recruited from 3 high schools and 1 university. Study staff conducted informational sessions. Students interested in participating were given consent forms to take home, and invited to visit our clinic for STI screening. During clinic visits, participants completed a self-administered questionnaire and provided a urine specimen for STI testing using a nucleic acid amplification test. RESULTS: Between August 2014 and March 2015, 463 high school and 165 university students collected consent forms. Of these, 293 (63%) from high schools versus 158 (95%) from university attended clinic for STI screening (P < 0.001). Of the 150 (33%) who reported any history of insertive vaginal sex, 78 (52.0%) reported condom use at the last sex act, 31 (20.7%) reported using modern nonbarrier contraceptive methods, and 37 (24.7%) reported not using any contraception at the last sex act. Twenty-six (5.8%) participants were diagnosed with STIs (7 [1.6%] Neisseria gonorrhoeae, 16 [3.6%] Chlamydia trachomatis, 3 [0.7%] Trichomonas vaginalis). In multivariable analyses, reporting receptive vaginal sex without a condom was associated with having a laboratory confirmed STI (odds ratio, 6.21; 95% confidence interval, 1.72-22.28). CONCLUSIONS: These findings support the need for reproductive health interventions to reduce the risk of STIs in a population of adolescent girls and young women in East Africa.

RESUMEN

BACKGROUND: Clinicians in low resource settings in malaria endemic regions face many challenges in diagnosing and treating febrile illnesses in children. Given the change in WHO guidelines in 2010 that recommend malaria testing prior to treatment, clinicians are now required to expand the differential when malaria testing is negative. Prior studies have indicated that resource availability, need for additional training in differentiating non-malarial illnesses, and lack of understanding within the community of when to seek care play a role in effective diagnosis and treatment. The objective of this study was to examine the various factors that influence clinician behavior in diagnosing and managing children presenting with fever to health centres in Kenya. METHODS: A total of 20 clinicians (2 paediatricians, 1 medical officer, 2 nurses, and 15 clinical officers) were interviewed, working at 5 different government-sponsored public clinic sites in two areas of Kenya where malaria is prevalent. Clinicians were interviewed one-on-one using a structured interview technique. Interviews were then analysed qualitatively for themes. RESULTS: The following five themes were identified: (1) Strong familiarity with diagnosis of malaria and testing for malaria; (2) Clinician concerns about community understanding of febrile illness, use of traditional medicine, delay in seeking care, and compliance; (3) Reliance on clinical guidelines, history, and physical examination to diagnose febrile illness and recognize danger signs; (4) Clinician discomfort with diagnosis of primary viral illness leading to increased use of empiric antibiotics; and (5) Lack of resources including diagnostic testing, necessary medications, and training modalities contributes to the difficulty clinicians face in assessing and treating febrile illness in children. These themes persisted across all sites, despite variation in levels of medical care. Within these themes, clinicians consistently expressed a need for reliable basic testing, especially haemograms and bacterial cultures. Clinicians discussed the use of counseling and education to improve community understanding of febrile illness in order to decrease preventable deaths in children. CONCLUSION: Results of this study suggest that since malarial testing has become more widespread, clinicians working in resource-poor environments still face difficulty when evaluating a child with fever, especially when malaria testing is negative. Improving access to additional diagnostics, continuing medical education, and ongoing evaluation and revision of clinical guidelines may lead to more consistent management of febrile illness by providers, and may potentially decrease prescription of unnecessary antibiotics. Additional interventions at the community level may also have an important role in managing febrile illness, however, more studies are needed to identify targets for intervention at both the clinic and community levels.

RESUMEN

BACKGROUND: Kenyan female sex workers (FSWs) have a high HIV prevalence, increasing their tuberculosis (TB) risk. Despite recommendations that HIV-positive individuals be offered isoniazid preventive therapy (IPT), uptake has been limited. METHODS: In this longitudinal cohort of HIV-positive FSWs, we retrospectively characterized the IPT care cascade between March 2000 and January 2010, including reasons for cascade loss or appropriate exit. Cascade success required completion of 6 months of IPT. Baseline characteristics were assessed as potential correlates of cascade loss using multivariable logistic regression. RESULTS: Among 642 HIV-positive FSWs eligible for IPT evaluation, median age was 31 years (IQR 26-35) with median CD4 lymphocyte count of 409 (IQR 292-604) cells per cubic millimeter. There were 249 (39%) women who successfully completed 6 months of IPT, 157 (24%) appropriately exited the cascade, and 236 (37%) were cascade losses. Most cascade losses occurred at symptom screen (38%, 90/236), chest radiograph evaluation (28%, 66/236), or during IPT treatment (30%, 71/236). Twenty-nine women were diagnosed with tuberculosis, including one after IPT initiation. Most women initiating IPT completed the course (71%, 249/351); <5% had medication intolerance. Younger women [<25 and 25-35 vs. >35 years; adjusted odds ratio (AOR) 2.65, 95% confidence interval (CI): 1.46 to 4.80 and AOR 1.78, 95% CI: 1.13 to 2.80, respectively], and those evaluated for IPT after antiretroviral availability in 2004 (AOR 1.92, 95% CI: 1.31 to 2.81), were more likely to be cascade losses. CONCLUSIONS: Implementation of IPT among HIV-positive FSWs in Kenya is feasible. However, significant losses along the IPT care cascade underscore the need for strategies improving retention in care.

RESUMEN

BACKGROUND: To successfully develop and implement school-based sexual health interventions for adolescent girls, such as screening for Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis, it is important to understand parents' and teachers' attitudes towards sexual health education and acceptability of sexually transmitted infection (STI) screening interventions. METHODS: In this qualitative study, we approached parents and teachers from three high schools to participate in in-depth interviews (IDIs) and focus-group discussions (FGDs). Parents and teachers were asked about their general knowledge of STIs and sexual health education. In addition, they were asked whether they would support utilizing outreach to schools to facilitate provision of sexual health education and screening for STIs in adolescent girls. Data were audio-recorded, transcribed, and translated into English. An initial coding matrix was developed and refined throughout the coding process. Transcripts were coded by two researchers and analyzed using the content analysis approach. RESULTS: We conducted 10 IDIs (5 parents and 5 teachers) and 4 FGDs (2 with parents, 2 with teachers, total of 26 participants). Most parents reported few or no discussions regarding STIs with their adolescent girls. Parents were more comfortable discussing consequences of sexual activity including loss of virginity and the potential for pregnancy. Parents tended to place responsibility for sexual health education with teachers. The teachers, in turn, provided basic sexual and reproductive health education including puberty, abstinence, and overview of STIs. Both parents and teachers found the idea of screening for STIs in adolescent girls to be acceptable, and were comfortable with research staff contacting girls through informational meetings at schools. Parents felt that adolescents' STI screening results should be shared with their parents. CONCLUSION: In this African setting, parents and teachers provide limited sexual health education, with a focus on negative consequences including loss of virginity, pregnancy, and risk for STIs. Nonetheless, both parents and teachers were supportive of STI screening for adolescent girls, beginning with school-based informational meetings for the girls. Research and programs that aim to provide STI screening in this setting must offer treatment and address the issue of whether results will be disclosed to parents.

RESUMEN

OBJECTIVE: Young women bear the greatest burden of sexually transmitted infections (STIs), so it is important to identify and address barriers to STI screening in this population. We conducted a qualitative study to explore the feasibility of STI screening among adolescent girls and young women in Mombasa, Kenya. METHODS: We conducted 17 in-depth interviews (IDIs) (8 with adolescent girls and 9 with young women) and 6 focus group discussions (FGDs) (4 with adolescent girls and 2 with young women, total 55 participants). The audio recordings for the IDIs and FGDs were translated and transcribed into English. Transcripts were independently reviewed by two researchers, and a set of codes was designed to help analyze the data using the content analysis approach. Data content was then analyzed manually and digitally using ATLAS.ti, and consensus was reached on central and specific emergent themes discussed by the research team. RESULTS: Adolescent girls and young women in Mombasa, Kenya expressed willingness to participate in STI screening. A major incentive for screening was participants' desire to know their STI status, especially following perceived high-risk sexual behavior. Lack of symptoms and fear of positive test results were identified as barriers to STI screening at the individual level, while parental notification and stigmatization from parents, family members and the community were identified as barriers at the community level. Uncomfortable or embarrassing methods of specimen collection were an additional barrier. Thus, urine-based screening was felt to be the most acceptable. CONCLUSION: Kenyan adolescent girls and young women seem willing to participate in screening for STIs using urine testing. Addressing stigmatization by parents, health care workers and the community could further facilitate STI screening in this population.

RESUMEN

OBJECTIVE: Many HIV-positive women now live well beyond menopause. Postmenopausal women are no longer at risk for pregnancy, and some studies suggest that they may use condoms less often than premenopausal women. This study tests the hypothesis that, in HIV-positive women who report trading sex for cash or in-kind payment, unprotected sex is more common at postmenopausal visits compared with premenopausal visits. DESIGN: Prospective cohort study of HIV-positive women ≥16 years old in Mombasa, Kenya. METHODS: At enrollment and monthly follow-up visits, participants completed a standardized interview. Study clinicians collected genital samples at enrollment and quarterly visits. Menopausal status was assessed annually. The primary outcome of unprotected sex was determined by detection of prostate specific antigen (PSA) in vaginal secretions. RESULTS: This study followed 404 HIV-positive women who contributed 2753 quarterly examination visits. Detection of PSA was less frequent at postmenopausal visits compared with premenopausal visits [55/554, 10.5% versus 394/2199, 17.9%; relative risk (RR) 0.58, 95% confidence interval (CI): 0.39 to 0.87]. Adjusting for age diminished the association between menopause and PSA detection (adjusted RR 0.73, 95% CI: 0.47 to 1.14). At visits where women reported sexual activity in the past week, they reported similar rates of 100% condom use at postmenopausal and premenopausal visits (RR 0.99, 95% CI: 0.87 to 1.13). CONCLUSIONS: In this population of high-risk HIV-positive Kenyan women, postmenopausal status was not associated with a greater risk of unprotected sex. The relationship between menopause and unprotected sex is likely context specific and may differ with varying risk groups, regions, and levels of exposure to sexual health education.

RESUMEN

BACKGROUND: Studies of alcohol use and sexual behavior in African populations have primarily been cross-sectional, used nonvalidated measures of alcohol use, or relied on self-reported sexual risk endpoints. Few have focused on human immunodeficiency virus (HIV)-positive women. METHODS: Longitudinal data were collected from a cohort of HIV-positive Kenyan female sex workers. At enrollment and annual visits, participants were asked about past-year alcohol use using the Alcohol Use Disorders Identification Test (AUDIT). The primary endpoint was detection of prostate-specific antigen (PSA) in vaginal secretions at quarterly examinations. Associations between hazardous/harmful alcohol use (AUDIT score ≥7), PSA detection, and secondary measures of sexual risk were evaluated using generalized estimating equations with a log binomial regression model. RESULTS: A total of 405 women contributed 2750 vaginal samples over 606 person-years of follow-up. Hazardous/harmful alcohol use was reported at 16.6% of AUDIT assessments and was associated with higher risk of PSA detection (relative risk 1.50; 95% confidence interval, 1.11-2.01) relative to no alcohol use. This association was attenuated and no longer statistically significant, after adjusting for age, work venue, intimate partner violence, depression, and partnership status (adjusted relative risk, 1.13; 95% confidence interval, 0.82-1.56). In exploratory analyses, alcohol use was associated with self-report of unprotected sex and with sexually transmitted infection acquisition. CONCLUSIONS: Although hazardous/harmful alcohol use was not associated with detection of PSA in adjusted analysis, associations with secondary outcomes suggest that alcohol use is at least a marker of sexual risk behavior.
