Tobacco control research on the African continent: a 22-year literature review and network analysis.

OBJECTIVE: Describe the landscape of tobacco-related topics, funders and institutional networks in Africa. DATA SOURCES: We searched PubMed, Embase and African Index Medicus for published articles from January 1996 to August 2018 in any language. STUDY SELECTION: Two researchers independently reviewed titles and abstracts for a focus on nicotine or tobacco product(s) and describe data or recommendations specific to Africa. Ultimately, 818 articles were identified. DATA EXTRACTION: Three independent coders conducted qualitative analyses of articles and extracted funders, study populations, countries of research focus, research topics, tobacco products, study design and data source. A bibliometric analysis estimated coauthorship networks between the countries of authors' primary institutional affiliation. DATA SYNTHESIS: All 54 African countries were represented in two or more articles. The coauthorship network included 2714 unique authors representing 90 countries. Most articles employed a cross-sectional study design with primary data collection, focused on cigarettes and studied use behaviour. Few articles examined tobacco farming or interventions for cessation or prevention. The most frequently cited funder was the US National Institutes of Health (27.2%). A range of coauthorship patterns existed between African institutions with some coauthoring with one institution while others coauthored with 761 institutions in other African countries. CONCLUSIONS: The literature review identified the need for implementation research for tobacco control interventions and policies, economic and development impacts of tobacco use research, and tobacco industry and tobacco production and farming research. Numbers of research collaborations between institutions in Africa vary, suggesting the need for regional institutional capacity building.

Resumption of Sexual Intercourse Among Postnatal Women Enrolled on Lifelong Antiretroviral Therapy in Uganda.

The postnatal period is critical to the delivery of interventions aimed at improving maternal health outcomes. This study examined the timing to resumption of sexual intercourse and associated factors among postnatal women living with HIV (WLWH) in Uganda. A sample of 385 women was drawn from a larger prospective cohort study conducted between 2013 and 2015. We used survival analysis to estimate the postpartum time periods during which women had a higher risk of sexual intercourse resumption within 6 months after childbirth. Cox proportional hazards regression was used to examine associated factors with sexual intercourse resumption. The cumulative probability of sexual intercourse resumption was lowest (6.2%) in the sub-acute postpartum period (1-45 days since delivery) and highest (88.2%) in the delayed postpartum period (151-183 days since delivery). Having a live-term baby (adjusted HR 0.52, 95% CI 0.31-0.85, p = 0.01) and an advanced education (adjusted HR 0.63, 95% CI 0.40-0.98, p = 0.04) were associated with a lower risk of sexual intercourse resumption. Desire for another child (adjusted HR 1.36, 95% CI 1.08-1.73, p = 0.01), having a sexual partner (adjusted HR 5.97, 95% CI 3.10-11.47, p < 0.001) and contraceptive use (adjusted HR 2.21, 95% CI 1.65-2.95, p < 0.001) were associated with a greater risk of sexual intercourse resumption. However, only 1 in 4 women who resumed sexual intercourse by the 90th day after childbirth, reported currently using contraception. HIV programs should focus on supporting postnatal women to align the timing of sexual intercourse resumption with their return to contraceptive use. Interventions aimed at improving contraceptive uptake among postnatal WLWH should target the delayed postpartum period.

Health providers' experiences, perceptions and readiness to provide HIV services to men who have sex with men and female sex workers in Uganda - a qualitative study.

BACKGROUND: Access to HIV services among men who have sex with men (MSM) and female sex workers (FSWs) remains suboptimal globally. While the reasons for this dismal performance have been documented, limited evidence exists on the experiences, perceptions and readiness of health providers to provide HIV services to MSM and FSWs. METHODS: This analysis uses data collected from 48 key informants (health providers in public and private health facilities) as part of a larger study conducted in 12 districts of Uganda between October and December 2013. Data were collected on health providers' experiences and readiness to provide HIV services to MSM and FSWs and their perceptions on the effect of existing legislation on HIV services provision to MSM and FSWs. Data were captured verbatim, transcribed and analyzed following a thematic framework approach. RESULTS: All health providers reported that they had ever provided HIV services to FSWs and a majority of them were comfortable serving them. However, no health provider had ever served MSM. When asked if they would be willing to serve MSM, nearly three-quarters of the health providers indicated that they would be bound by the call of duty to serve them. However, some health providers reported that they "would feel very uncomfortable" handling MSM because they engage in "a culture imported into our country". A majority of the health providers felt that they did not have adequate skills to effectively serve MSM and called for specific training to improve their clinical skills. There were mixed reactions as to whether existing criminal laws would affect MSM or FSWs access to HIV services but there was agreement that access to HIV services, under the existing laws, would be more constrained for MSM than FSWs since society "does not blame FSWs [as much as it does] with MSM". CONCLUSION: A majority of the health providers were generally comfortable serving FSWs but there were strong homophobic tendencies towards MSM. A majority of the health providers lacked skills in how to handle MSM. Interventions aimed at improving health providers' skills in handling MSM while minimizing the negative attitude towards them are urgently needed.

Knowledge and correlates of use of safer conception methods among HIV-infected women attending HIV care in Uganda.

BACKGROUND: Many people living with HIV would like to have children but family planning (FP) services often focus on only contraception. Availability of safer conception services is still very low in most low income countries. In this study we assessed the knowledge and use of safer conception methods (SCM) among HIV infected women in HIV care in Uganda to inform integration of safer conception in existing FP services. METHODS: Data were accrued from a nationally representative cross-sectional survey of 5198 HIV+ women aged 15-49 years from 245 HIV clinics in Uganda. Knowledge and use of safer conception methods and associated factors were determined. The measure of association was prevalence ratio (PR) with corresponding 95% confidence intervals, obtained using a modified Poisson regression via generalized linear models. All the analyses were conducted using STATA version 12.0. RESULTS: Overall knowledge of any safer conception method was 74.1% (3852/5198). However only 13.2% knew 3 to 4 methods, 18.9% knew only 2 methods and 42% knew only one method. Knowledge of specific SCM was highest for timed unprotected intercourse (TUI) at 39% (n = 2027) followed by manual self-insemination (MSI) at 34.8% (n = 1809), and pre-exposure prophylaxis (PrEP) at 24.8% (n = 1289). Knowledge of SCM was higher in the Eastern region (84.8%, P < 0.001), among women in HIV-discordant relationships (76.7%, p < 0.017), and those on ART (74.5%, p < 0.034). Overall, 1796 (34.6%) women were pregnant or reported a birth in the past 2 years-overall use of SCM in this group was 11.6% (209/1796). The odds of use of SCM were significantly lower in Kampala [adj. PR = 0.489(0.314, 0.764)] or Eastern region [adj.PR = 0.244; (0.147, 0.405)] compared to Northern region. Higher odds of SCM use were associated with HIV status disclosure to partner [adj.PR = 2.613(1.308, 5.221)] and sero-discordant compared to HIV+ concordant relationship [adj.PR = 1.637(1.236, 2.168)]. Pre-existing knowledge of any one SCM did not influence SCM use. CONCLUSIONS: Knowledge and use of SCM among HIV+ women in care is low. Efforts to improve HIV status disclosure, integration of safer conception into FP and HIV services and regional efforts to promote sensitization and access to safer conception can help to increase uptake of safer conception methods.

Facilitators and barriers to uptake and adherence to lifelong antiretroviral therapy among HIV infected pregnant women in Uganda: a qualitative study.

BACKGROUND: In 2012, Uganda started implementing lifelong antiretroviral therapy (ART) for prevention of mother to child transmission (PMTCT) in line with the WHO 2012 guidelines. This study explored experiences of HIV infected pregnant and breastfeeding women regarding barriers and facilitators to uptake and adherence to lifelong ART. METHODS: This was a cross-sectional qualitative study conducted in three districts (Masaka, Mityana and Luwero) in Uganda, between February and May 2014. We conducted in-depth interviews with 57 pregnant and breastfeeding women receiving care in six health facilities, who had been on lifelong ART for at least 6 months. Data analysis was done using a content thematic approach with Atlas-ti software. RESULTS: Initiation of lifelong ART was done the same day the mother tested HIV positive. Several women felt the counselling was inadequate and had reservations about taking ART for life. The main motivation to initiate and adhere to ART was the desire to have an HIV-free baby. Adherence was a challenge, ranging from not taking the drugs at the right time, to completely missing doses and clinic appointments. Support from their male partners and peer family support groups enhanced good adherence. Fear to disclose HIV status to partners, drug related factors (side effects and the big size of the tablet), and HIV stigma were major barriers to ART initiation and adherence. Transition from antenatal care to HIV chronic care clinics was a challenge due to fear of stigma and discrimination. CONCLUSIONS: In order to maximize the benefits of lifelong ART, adequate preparation of women before ART initiation and on-going support through family support groups and male partner engagement are critical, particularly after birth and cessation of breastfeeding.

"When they know that you are a sex worker, you will be the last person to be treated": Perceptions and experiences of female sex workers in accessing HIV services in Uganda.

BACKGROUND: HIV prevalence among female sex workers (FSWs) in high burden countries in sub-Saharan Africa varies between 24 and 72%, however their access to HIV services remains limited. This study explored FSWs' perspectives of the barriers and opportunities to HIV service access in Uganda. METHODS: The cross-sectional qualitative study was conducted between October and December 2013. Twenty-four focus group discussions were conducted with 190 FSWs in 12 districts. Data were analysed using manifest content analysis, using Atlas.ti software, based on the socio-ecological model. RESULTS: FSWs indicated that HIV services were available and these included condoms, HIV testing and treatment, and management of sexually transmitted infections. However, access to HIV services was affected by several individual, societal, structural, and policy related barriers. Individual level factors included limited awareness of some prevention services, fears, and misconceptions while societal stigma was prominent. Structural and policy level barriers included inconvenient hours of operation of the clinics, inflexible facility based distribution of condoms, interuptions in the supply of condoms and other commodities, and limited package of services with virtually no access to lubricants, HIV pre- and post-exposure prophylaxis, and support following client perpetrated violence. Policies such as partner testing and involvement at antenatal care, and using only one facility for antiretroviral drug refills hindered HIV service uptake and retention in care. FSWs had major concerns with the quality of services especially discrimination and rude remarks from providers, denial or delay of services, and potential for breach of confidentiality. However, some FSWs reported positive experiences including interface with friendly providers and participated in formal and informal FSW groups, which supported them to access health services. CONCLUSION: Despite availability of services, FSWs faced major challenges in access to services. Comprehensive multilevel interventions targeting individual, societal, structural and policy level barriers are required to increase access to HIVservices among FSWs in Uganda. Policy and institutional adjustments should emphasize quality friendly services and expanding the package of services to meet the needs of FSWs.

HIV status disclosure and associated outcomes among pregnant women enrolled in antiretroviral therapy in Uganda: a mixed methods study.

BACKGROUND: Disclosure of HIV positive status to sexual partners is promoted by HIV prevention programs including those targeting the prevention of mother-to-child transmission. Among other benefits, disclosure may enhance spousal support and reduce stigma, violence and discrimination. HIV status disclosure and associated outcomes were assessed among a cohort of women, newly initiating lifelong antiretroviral therapy in Uganda between October 2013 and May 2014. METHODS: This was a mixed method study, drawing data from a prospective cohort study of 507 HIV positive pregnant women on lifelong antiretroviral therapy, who were followed for four months to determine disclosure and its outcomes. Women were recruited from three facilities for the cohort study; in addition, fifty-seven women were recruited to participate in qualitative interviews from six facilities. Factors associated with spousal support and negative outcomes were determined using random-effects logistic regression in two separate models, with prevalence ratio as measure of association. In-depth interviews were used to document experiences with disclosure of HIV status. RESULTS: Overall HIV status disclosure to at least one person was high [(375/507), 83.7%]. Nearly three-quarters [(285/389), 73.3%], had disclosed to their spouse by the fourth month of follow up post-enrolment. Among married women, spousal support was high at the first 330/407 (81.1%) and second follow-up 320/389 (82.2%). The majority of women who reported spousal support for either antenatal care or HIV-related care services had disclosed their HIV status to their spouses (adj.PR = 1.17; 95% CI: 1.02-1.34). However, no significant differences were observed in the proportion of self-reported negative outcomes by HIV status disclosure (adj.PR = 0.89; 95% CI: 0.56-1.42). Qualitative findings highlighted stigma and fear of negative outcomes as the major barriers to disclosure. CONCLUSION: HIV status disclosure to partners by pregnant women on lifelong antiretroviral therapy was associated with increased spousal support, but was impeded by fear of adverse outcomes such as stigma, discrimination and violence. Interventions to reduce negative outcomes could enhance HIV status disclosure.

A phone-based tobacco use cessation program for people living with HIV in Uganda and Zambia: study protocol for a randomized controlled trial.

BACKGROUND: Nicotine replacement therapy (NRT) and short messaging service (SMS)-based tobacco cessation interventions have demonstrated effectiveness in reducing tobacco use in many populations, but evidence is needed on which tailored treatments are most efficacious in meeting the complex medical and psychosocial factors confronting people living with HIV (PLWH) in sub-Saharan Africa (SSA). This paper describes the protocol of a study to test the efficacy of both NRT and a tailored SMS-based tobacco use cessation intervention among PLWH in Uganda and Zambia. METHODS: In a randomized controlled trial, 800 adult PLWH who use tobacco will be recruited by health care professionals at HIV treatment centers where they are receiving care. Participants will be randomized to one of the four study arms: (1) standard of care [SOC; brief clinician advice to quit combined with HIV education and information aimed at encouraging HIV treatment adherence (with no mention of tobacco) delivered via text messages]; (2) SOC + 12 weeks of NRT; (3) SOC + 6 weeks of SMS text messages to support quitting tobacco use (SMS); or (4) SOC + NRT + SMS. Participants will receive a cell phone and solar panel with power bank for charging the phone. The main outcome is cessation of tobacco use by study participants verified by urinary cotinine (< 15 ng/mL) at 6 months post-enrollment. As a secondary tobacco use outcome, we will measure 7-day point-prevalence abstinence (7 consecutive days of no tobacco use) measured by self-report and biochemically-verified at 4 weeks, 8 weeks, and 3 months post enrollment. DISCUSSION: Our study will provide insight into the efficacy, feasibility and applicability of delivering tobacco cessation interventions through health care professionals combined with tailored tobacco cessation SMS text messaging in two countries with different tobacco use patterns, policy environments, and health care resources and provide needed information to providers and policymakers looking for cost-effective tobacco cessation interventions. The previously tested SMS-platform to be used in our study is uniquely positioned to be scaled in low- and middle-income countries worldwide, in which case evidence of even modest success in reducing the prevalence of tobacco consumption among PLWH could confer enormous health and economic benefits.

'. . . if you bring the kit home, you [can] get time and test together with your partner': Pregnant women and male partners' perceptions regarding female partner-delivered HIV self-testing in Uganda - A qualitative study.

In 2015, the World Health Organization reported that more than 60 million people were tested for HIV in 122 low- and middle-income countries between 2010 and 2014. Despite this level of progress, over 40% of people living with HIV remain unaware of their HIV status. This calls for innovative approaches to improve uptake of HIV testing services, including use of HIV self-test (HIVST) kits. We conducted a cross-sectional, qualitative study to assess pregnant women and their male partners' perceptions regarding female partner-delivered HIVST kits. This study was conducted at two health facilities in Central Uganda between November and December 2015. Data were collected on pregnant women's willingness to take HIVST kits to their male partners and other household members using eight focus group discussions and 30 in-depth interviews. Data were analyzed following a thematic framework approach. Overall, pregnant women were willing to take HIVST kits to their partners and other household members, with the exception of their cowives. Male partners were willing to use HIVST kits brought by their female partners. Our findings suggest that secondary distribution of HIVST kits through female partners is acceptable and has the potential to improve male partner and household-member HIV testing.

Uptake and correlates of cervical cancer screening among HIV-infected women attending HIV care in Uganda.

BACKGROUND: Human immunodeficiency virus (HIV)-infected women are at high risk of cervical cancer. OBJECTIVE: This study assessed uptake and correlates of cervical screening among HIV-infected women in care in Uganda. METHODS: A nationally representative cross-sectional survey of HIV-infected women in care was conducted from August to November 2016. Structured interviews were conducted with 5198 women aged 15-49 years, from 245 HIV clinics. Knowledge and uptake of cervical screening and human papillomavirus (HPV) vaccination were determined. Correlates of cervical screening were assessed with modified Poisson regression to obtain prevalence ratios (PRs) using Stata version 12.0. RESULTS: Overall, 94.0% (n = 4858) had ever heard of cervical screening and 66% (n = 3732) knew a screening site. However, 47.4% (n = 2302) did not know the schedule for screening and 50% (n = 2409) did not know the symptoms of cervical cancer. One-third (33.7%; n = 1719) rated their risk of cervical cancer as low. Uptake of screening was 30.3% (n = 1561). Women who had never been screened cited lack of information (29.6%; n = 1059) and no time (25.5%; n = 913) as the main reasons. Increased likelihood of screening was associated with receipt of HIV care at a level II health center [adj. PR 1.89, 95% confidence interval (CI) 1.29-2.76] and private facilities (adj. PR 1.68, 95% CI 1.16-3.21), knowledge of cervical screening (adj. PR 2.19, 95% CI 1.78-2.70), where to go for screening (adj. PR 6.47, 95% CI 3.69-11.36), and low perception of risk (adj. PR 1.52, 95% CI 1.14-2.03). HPV vaccination was 2%. CONCLUSIONS: Cervical screening and HPV vaccination uptake were very low among HIV-infected women in care in Uganda. Improved knowledge of cervical screening schedules and sites, and addressing fears and risk perception may increase uptake of cervical screening in this vulnerable population.

"If You Tell People That You Had Sex with a Fellow Man, It Is Hard to Be Helped and Treated": Barriers and Opportunities for Increasing Access to HIV Services among Men Who Have Sex with Men in Uganda.

BACKGROUND: Despite the high HIV prevalence among men who have sex with men (MSM) in sub-Saharan Africa, little is known about their access to HIV services. This study assessed barriers and opportunities for expanding access to HIV services among MSM in Uganda. METHODS: In October-December 2013, a cross-sectional qualitative study was conducted in 12 districts of Uganda. Semi-structured in-depth interviews were conducted with 85 self-identified MSM by snowball sampling and 61 key informants including HIV service providers and policy makers. Data were analysed using manifest content analysis and Atlas.ti software. RESULTS: Three quarters of the MSM (n = 62, 72.9%) were not comfortable disclosing their sexual orientation to providers and 69 (81.1%) felt providers did not respect MSM. Half (n = 44, 51.8%) experienced difficulties in accessing health services. Nine major barriers to access were identified, including: (i) unwelcoming provider behaviours; (ii) limited provider skills and knowledge; (iii) negative community perceptions towards MSM; (iv) fear of being exposed as MSM; (v) limited access to MSM-specific services; (vi) high mobility of MSM, (vii) lack of guidelines on MSM health services; viii) a harsh legal environment; and ix) HIV related stigma. Two-thirds (n = 56, 66%) participated in MSM social networks and 86% of these (48) received support from the networks to overcome barriers to accessing services. CONCLUSIONS: Negative perceptions among providers and the community present barriers to service access among MSM. Guidelines, provider skills building and use of social networks for mobilization and service delivery could expand access to HIV services among MSM in Uganda.

Barriers to Condom Use among High Risk Men Who Have Sex with Men in Uganda: A Qualitative Study.

BACKGROUND: Unprotected sexual intercourse is a major risk factor for HIV transmission. Men who have sex with men (MSM) face challenges in accessing HIV prevention services, including condoms. However, there is limited in-depth assessment and documentation of the barriers to condom use among MSM in sub-Saharan Africa. In this paper, we examine the barriers to condom use among MSM in Uganda. METHODS: The data for this study were extracted from a larger qualitative study conducted among 85 self-identified adult (>18 years) MSM in 11 districts in Uganda between July and December 2013. Data on sexual behaviours and access and barriers to condom use were collected using semi-structured interviews. All interviews were audio-recorded and transcribed verbatim. This paper presents an analysis of data for 33 MSM who did not use condoms at last sex, with a focus on barriers to condom use. Analysis was conducted using the content analysis approach. RESULTS: Six major barriers to condom use were identified: Difficulties with using condoms, access challenges, lack of knowledge and misinformation about condom use, partner and relationship related issues, financial incentives and socio-economic vulnerability, and alcohol consumption. CONCLUSION: The findings suggest that several reasons account for lack of condom use among high-risk MSM. The findings are valuable to inform interventions needed to increase condom use among MSM.
