RESUMEN

BACKGROUND: Same-sex attracted men in Tanzania and globally carry a disproportionate burden of HIV. Drawing on qualitative research, this article explores healthcare providers' ideas and recommendations regarding how to improve HIV prevention among same-sex attracted men. METHODS: We carried out a qualitative study among healthcare workers in the cities of Dar es Salaam and Tanga in Tanzania between August 2018 and October 2019. Data were collected using qualitative methods of data collection, specifically in-depth interviews, focus group discussions, and participant observation. Study participants were recruited through a purposive sampling strategy that aimed to ensure variation in age, education, and work experience. Forty-eight interviews with 24 healthcare workers, six focus group discussions, and participant observation were conducted. A total of 64 persons participated in the study. RESULTS: This paper describes five different "ways of reasoning" that were identified among healthcare workers regarding how to strengthen HIV prevention among same-sex attracted men. One held that punitive measures should be taken to prevent HIV transmission, another that health services needed to become more friendly towards men who have sex with men, a third that healthcare workers should reach out to provide more education to this population, a fourth called for strengthened collaboration between healthcare providers and same-sex attracted men in healthcare delivery, and the fifth proposed that activistic efforts be taken to remove structural barriers for same-sex attracted men to access healthcare. CONCLUSION: When reflecting on what is needed to strengthen HIV prevention among men who have sex with men, healthcare workers described six different ideas. One was that restrictive and punitive measures ought to be taken to prevent HIV transmission through same-sex sex. The remaining five promoted understanding of and support for same-sex attracted men. They prescribed more healthcare education, measures to improve attitudes among healthcare workers, healthcare delivery with user involvement, and political action to achieve law reform. Finally, some study participants raised concerns about the implementation of the national comprehensive package for key populations.

RESUMEN

BACKGROUND: In response to the increasing burden of cancer in Tanzania, the Ministry of Health, Community Development, Gender, Elderly and Children launched National Cancer Treatment Guidelines (TNCTG) in February 2020. The guidelines aimed to improve and standardize oncology care in the country. At Ocean Road Cancer Institute (ORCI), we developed a theory-informed implementation strategy to promote guideline-concordant care. As part of the situation analysis for implementation strategy development, we conducted focus group discussions to evaluate clinical systems and contextual factors that influence guideline-based practice prior to the launch of the TNCTG. MATERIALS AND METHODS: In June 2019, three focus group discussions were conducted with a total of 21 oncology clinicians at ORCI, stratified by profession. A discussion guide was used to stimulate dialogue about facilitators and barriers to delivery of guideline-concordant care. Discussions were audio recorded, transcribed, translated, and analyzed using thematic framework analysis. RESULTS: Participants identified factors both within the inner context of ORCI clinical systems and outside of ORCI. Themes within the clinical systems included capacity and infrastructure, information technology, communication, efficiency, and quality of services provided. Contextual factors external to ORCI included interinstitutional coordination, oncology capacity in peripheral hospitals, public awareness and beliefs, and financial barriers. Participants provided pragmatic suggestions for strengthening cancer care delivery in Tanzania. CONCLUSION: Our results highlight several barriers and facilitators within and outside of the clinical systems at ORCI that may affect uptake of the TNCTG. Our findings were used to inform a broader guideline implementation strategy, in an effort to improve uptake of the TNCTGs at ORCI. IMPLICATIONS FOR PRACTICE: This study provides an assessment of cancer care delivery systems in a low resource setting from the unique perspectives of local multidisciplinary oncology clinicians. Situational analysis of contextual factors that are likely to influence guideline implementation outcomes is the first step of developing an implementation strategy for cancer treatment guidelines. Many of the barriers identified in this study represent actionable targets that will inform the next phases of our implementation strategy for guideline-concordant cancer care in Tanzania and comparable settings.

RESUMEN

Drawing on qualitative research in Dar es Salaam, Tanzania, this article explores how men who engage in sex with other men perceive their interactions with healthcare providers, and how they would prefer healthcare services to be organised and delivered. The paper describes the strengths and weaknesses men associate with private and public healthcare; the advantages and disadvantages they associate with dedicated clinics for sexual minority persons; what they conceive of as good healthcare services; and how they would characterise a good healthcare worker. The paper also presents recommendations made by study participants. These include the view that health services for same-sex attracted men should be developed and delivered in collaboration with such men themselves; that health workers should receive training on the medical needs as well as the overall circumstances of same-sex attracted men; and that there should be mechanisms that make healthcare available to poorer community members. We analyse men's views and recommendations in the light of theoretical work on trust and discuss the ways in which same sex attracted men look for signs that healthcare workers and healthcare services are trustworthy.

RESUMEN

Early age at first sex experience has been attributed to medical and psychological consequences, including practice of risk behaviors and HIV infection later in life. Studies have examined early heterosexual experience, but little is known about early anal sexual experience among men who have sex with men (MSM) in Africa. We conducted a time to event analysis to examine the extent and role of early anal sexual experience and HIV risk and infection in the largest MSM survey in Africa. A total of 753 MSM with a mean age of 26.5 years and that at first anal sexual experience of 18.3 years participated. Of those who participated, 29.0% (219/753) had their first anal sexual experience at age below 15. MSM reporting early anal sexual experience were young, had men as first sexual partner (adjusted hazard ratio-AHR, 4.75; 95%CI: 3.51-6.43), assumed receptive position during last anal sex (AHR, 3.25; 95%CI: 2.42-4.35), had anal sex as first penetrative sexual experience (AHR, 5.05, 95%CI; 3.68-6.97), had unprotected first anal sex (AHR, 1.55, 95%CI: 1.03-2.33), not preferring women for sex (AHR, 2.78; 95%CI: 2.11-3.67), had non-consensual first sex (AHR, 1.53, 95%CI: 1.10-9.41), and HIV positive (AHR, 1.75; 95%CI: 1.21-2.50). A third of MSM engaged in anal sex at an early age and were more likely to report sexual abuse, practice HIV risk behaviors, and been HIV seropositive. Roll-out of the existing Comprehensive Guideline for HIV Treatment and Care for key population in Tanzania should be implemented alongside measures addressing sexual abuse among young people.

RESUMEN

BACKGROUND: Prevalence of HIV infection among people who inject drugs (PWID) has been reported to be higher than that of the general population. The present study aimed to estimate the prevalence of HIV infection and associated risk factors among PWID in Dar es Salaam, Tanzania, following the introduction of a comprehensive HIV intervention package (CHIP) for PWID in the country in 2014. METHODS: We conducted an integrated bio-behavioral survey (IBBS) among PWID using respondent-driven sampling (RDS) in Dar es Salaam, Tanzania, between October and December 2017. Data on socio-demographic characteristics and risky behaviors were collected through face-to-face interviews. Blood samples were collected and tested for HIV infection. We accounted for weighting in the analyses, and logistic regression was performed to assess risk factors for HIV infection. RESULTS: A total of 611 PWID (94.4% males and 5.6% females) with a median age of 34 years (IQR 29-38) were recruited. The overall prevalence of HIV infection was 8.7% (95% CI 6.5-10.9). The prevalence of HIV infections for males and females were 6.8% (95% CI 4.7-8.9%) and 41.2% (95% CI 23.7-58.6%) respectively. Adjusted weighted logistic regression analysis (WLRA) showed that being a female (aOR 19.1; 95% CI 5.9-61.8), injecting drugs for more than 10 years (aOR = 7.32; 95% CI 2.1-25.5) compared to 1 year or less and being 45 years or older (aOR = 34.22; 95% CI 2.4-489.5) compared to being 25 years or younger were associated with increased odds of HIV infection. Use of a sterile needle at last injection decreased odds of HIV infection (aOR = 0.3; 95% CI 0.1-0.8). CONCLUSIONS: The present study observed a decline in prevalence of HIV infections among PWID in Dar es Salaam (8.7%) compared to a previous estimate of 15.5% from an IBBS conducted in 2013. Despite the decrease, HIV prevalence remains high among PWID compared to the general population, and women are disproportionally affected. The decline may be possibly attributed to the on-going implementation of CHIP for PWID, highlighting the need for strengthening the existing harm reduction interventions by incorporating access to sterile needle/syringe and addressing the layered risks for women.

RESUMEN

BACKGROUND: While there are indications of declining HIV infection rates in the general population globally, Tanzania included, men who have sex with men (MSM), female sex workers (FSW) and people who inject drugs (PWID), now called Key Populations (KP) for HIV epidemic have 2-20 times higher infections rates and contributes up to 30% of new HIV infection. Tanzania have developed a Comprehensive Guideline for HIV prevention among key population (CHIP) to address the epidemic among KPs. However, these populations are stigmatized and discriminated calling for innovative approaches to improve access to CHIP. This project seeks to test the effectiveness of healthcare workers and peer-to-peer engagement in promoting access to CHIP among HIV at risk populations in Tanzania. METHODS: A quasi-experimental design involving Dar es Salaam City as an intervention region and Tanga as a control region will be done. Using respondent driven sampling, 1800 at risk population (900 from Intervention site and 900 from control site) will be recruited at baseline to identify pull and push factors for health services access. Stakeholder's consultation will be done to improve training contents for CHIP among health care workers and peers. Effectiveness of healthcare workers training and peer engagement will be tested using a quasi-experimental design. DISCUSSION: The results are expected to co-create service provision and improve access to services among KPs as a human right, reverse HIV infection rates among KPs and the general population, and improve social and economic wellbeing of Tanzanian. TRIAL REGISTRATION: Retrospectively registered on 28th August, 2019 with International Standard Randomized Clinical Trial Number ( ISRCTN11126469 ).

RESUMEN

BACKGROUND: Chronic HCV infection causes substantial morbidity and mortality and, in co-infection with HIV, may result in immunological and virological failure following antiretroviral treatment. Estimates of HCV infection, co-infection with HIV and associated risk practices among PWID are scarce in Africa. This study therefore aimed at estimating the prevalence of HCV and associated risk factors among PWID in the largest metropolitan city in Tanzania to inform WHO elimination recommendations. METHODS: An integrated bio-behavioral survey using respondent-driven sampling was used to recruit PWID residing in Dar es Salaam, Tanzania. Following face-to-face interviews, blood samples were collected for HIV and HCV testing. Weighted modified Poisson regression modeling with robust standard errors was used in the analysis. RESULTS: A total of 611 PWID with a median age of 34 years (IQR, 29-38) were recruited through 4 to 8 waves. The majority of participants (94.3%) were males, and the median age at first injection was 24 years (IQR, 19-30). Only 6.55% (40/611) of participants reported to have been enrolled in opioid treatment programs. The weighted HCV antibody prevalence was 16.2% (95%CI, 13.0-20.1). The corresponding prevalence of HIV infection was 8.7% (95%CI, 6.4-11.8). Of the 51 PWID who were infected with HIV, 22 (43.1%) were HCV seropositive. Lack of access to clean needles (adjusted prevalence ratio (APR), 1.76; 95%CI, 1.44; 12.74), sharing a needle the past month (APR, 1.72; 95%CI, 1.02; 3.00), not cleaning the needle the last time shared (APR, 2.29; 95%CI, 1.00; 6.37), and having unprotected not using a transactional sex (APR, 1.87; 95%CI, 1.00; 3.61) were associated with increased risk of HCV infection. On the other hand, not being on opioid substitution therapy was associated with 60% lower likelihood of infection. CONCLUSIONS: The HCV antibody prevalence among PWID is lower than global estimates indicating potential for elimination. Improving access to safe injecting paraphernalia, promoting safer injecting practices is the focus of prevention programing. Screening for HIV/HCV co-infection should be intensified in HIV care, opioid substitution programs, and other point of care for PWID. Use of direct-acting antiretroviral treatment would accelerate the achievement of hepatitis infection elimination goal by 2030.

RESUMEN

OBJECTIVES: To determine the seroprevalence of HIV, STI and related risks among men who have sex with men (MSM) in Dodoma municipality, Tanzania. METHODS: A cross-sectional study using respondent-driven sampling was employed to recruit study participants aged 18 years and above. Data on sociodemographics, HIV/STI knowledge and sexual practices were collected. Blood samples were tested for HIV and selected STIs. RESULTS: A total of 409 participants aged from 18 to 60 years took part in this study. The median age at first anal intercourse was 15 years. At last anal intercourse, 37.5% practiced receptive, 47.5% insertive and 15.0% both insertive and receptive anal intercourse. The seroprevalence of HIV, herpes simplex virus 2 (HSV-2), syphilis, hepatitis B virus and hepatitis C virus were 17.4%, 38.5%, 0.2%, 5.4% and 3.4%, respectively. A third of MSM perceived their risk for HIV to be low and this was associated with unprotected sex (adjusted OR (AOR), 4.8, 95% CI 1.8 to 10.2). HIV seropositivity was also associated with HSV-2 (AOR, 5.0, 95% CI 3.01 to 11.21); having lived outside Dodoma (AOR 1.7, 95% CI 1.1 to 6.7); age above 25 years; (AOR 2.1, 95% CI 1.7 to 3.7); sexual relationship with a woman (AOR 5.6, 95% CI 3.9 to 12.8); assuming a receptive (AOR 7.1, 95% CI 4.8 to 17.4) or receptive and insertive (AOR 4.5, 95% CI 1.9 to 11.4) position during last anal intercourse; engaging in group sex (AOR 3.1, 95% CI 1.2 to 6.1) and the use of alcohol (AOR 3.9, 95% CI 1.1 to 9.2). CONCLUSIONS: HIV prevalence among MSM is five times higher compared with men in the general population in Dodoma. Perceived risk for HIV infection was generally low and low risk perception was associated with unprotected sex. STI, bisexuality and other behavioural risk factors played an important part in HIV transmission. The findings underscore the need for intensified HIV prevention programming addressing and involving key populations in Tanzania.

RESUMEN

BACKGROUND: Previous studies in Tanzania indicated that human immunodeficiency virus (HIV) prevalence among people who inject drugs (PWIDs) could be as high as 40%. We aim to provide data on the prevalence of HIV and sexually transmitted infection among PWIDs to inform national plans to get to zero. MATERIALS AND METHODS: Respondent-driven sampling was used to collect drug use, and sexual practices data among PWIDs aged 15 years and older. Blood samples were examined for HIV, herpes simplex virus type 2, syphilis, and hepatitis B. RESULTS: A total of 620 PWIDs with a median age of 32 (interquartile range, 17-52) participated in the study. Their use of drugs had typically started during adolescence. The prevalence of HIV was found to be 15.5%, whereas that of herpes simplex type 2 was 43.3%. Associated with an increased likelihood of HIV infection was being a female (adjusted odds ratio [aOR], 2.3; 95% confidence interval [CI], 1.0-3.6), sharing of syringes (aOR, 2.4; 95% CI, 1.1-6.1), used syringes hidden in public places (aOR, 5.1; 95% CI, 1.3-10.2), and having had a genital ulcer during the last 12 months before this survey. On the other hand, being educated, use of noninjectable drugs, access (aOR, 0.5; 95% CI, 0.2-0.8), and use of clean syringes (aOR, 0.3; 95% CI, 0.1-0.6) were associated with decreased likelihood of HIV infection. CONCLUSIONS: The prevalence of HIV infection among PWIDs in Dar es Salaam is 3 times higher than that in the general population. Behavioral and biological risk factors contribute to HIV transmission and needs to be addressed to be able to get to zero.

RESUMEN

BACKGROUND: Unsafe sexual practices continue to put adolescents at risk for a number of negative health outcomes in Tanzania. While there are some effective theory-based intervention packages with positive impact on important mediators of sexual behaviours, a context specific and tested intervention is urgently needed in Tanzania. PURPOSE: To develop and evaluate an intervention that will have a significant effect in reducing sexual initiation and promoting condom use among adolescents aged 12-14 in Dar es Salaam, Tanzania. DESIGN: A school-based Cluster Randomised Controlled Trial was conducted during 2011-2014 in Kinondoni Municipality. METHODS: A total of 38 public primary schools were randomly selected, of which half were assigned to the intervention and half to the control group based on their size and geographic location. Participants were interviewed using a self-administered questionnaire at baseline before the PREPARE intervention and then, 6 and 12 months following intervention. The primary outcomes were self-reported sex initiation and condom use during the past 6 months. Data analysis was done using Generalized Estimating Equation (GEE) modelling controlling for repeated measures and clustering of students within schools. RESULTS: A total of 5091 students were recruited at baseline, and interviewed again at 6 (n = 4783) and 12 months (n = 4370). Mean age of participants at baseline was 12.4 years. Baseline sociodemographic, psychometric and behavioural characteristics did not significantly differ between the two study arms. The GEE analysis indicated that the intervention had a significant effect on sexual initiation in both sexes after controlling for clustering and correlated repeated measures. A significantly higher level of action planning to use condoms was reported among female adolescent in the intervention arm than those in the control arm (p = 0.042). An effect on condom use behaviour was observed among male adolescent (p = 0.004), but not among female (p = 0.463). CONCLUSIONS: The PREPARE intervention had an effect in delaying self-reported sexual initiation among adolescents aged 12-14 in Dar es Salaam Tanzania. The intervention positively influenced action planning to use condoms for both sexes and increased actual condom use among male adolescents only. Future interventions addressing adolescent sexual and reproductive health should focus on impacting mediators of behaviour change.

RESUMEN

BACKGROUND: The Millennium Development Goal No 4 (MDG 4) requires countries to scale up interventions addressing malnutrition and other immediate determinants of burden of disease among children to reduce child mortality by two thirds by 2015, which is this year. Whereas globally some achievements have been registered, under-nourishment remains a significant problem in some developing countries such as Tanzania. This study set out to estimate the extent of stunting and its associated determinants to assess the progress made thus far towards achieving MDG 4 in Tanzania. METHODS: A random sample of 678 households with under-five children was selected from two randomly selected wards of Kongwa district in Dodoma region, Tanzania. The WHO anthropometric calculator, which computes Z-scores using a reference population, was used to process the anthropometric measurement data taken from all the participants. Children with height for age Z-score of less than 2 were categorised as stunted and coded as 1 and the rest were coded as 0. Proportions of stunting were compared using the chi-square test to determine the association between stunting and the independent variables. Multivariate logistic regression analysis was carried out to determine the Adjusted Odds Ratio (AOR) of the independent determinants of stunting. The cut-off for significant association was set at p = 0.05. All these analyses used the STATA 12 software. RESULTS: About half (49.7 %) of the children were stunted. This stunting was associated with belonging to households where the head of family was young (<35 years) (AOR = 0.67, 95 % CI 0.47-0.96, p = 0.031), young age of the mothers (AOR = 1.54, 95 % CI 1.06-2.24, p = 0.023), and economic variables such as owning a cellular phone (AOR = 0.66, 96 % CI 0.46-0.94, p = 0.023). CONCLUSIONS: Stunting was highly prevalent in Kongwa district despite general improvements in child nutritional status at the national level. Household characteristics and economic status were found to play a major role in child health. In this regard, disaggregated analyses are therefore important in identifying resilient areas in need of concerted efforts for the MDG 4 to be achieved nationwide.

RESUMEN

BACKGROUND: The need to develop capacity for health services and systems research (HSSR) in low and middle income countries has been highlighted in a number of international forums. However, little is known about the level of HSSR training in Sub-Saharan Africa (SSA). We conducted an assessment at four major East and Southern African universities to describe: a) the numbers of HSSR PhD trainees at these institutions, b) existing HSSR curricula and mode of delivery, and c) motivating and challenging factors for PhD training, from the trainees' experience. METHODS: PhD training program managers completed a pre-designed form about trainees enrolled since 2006. A desk review of existing health curricula was also conducted to identify HSSR modules being offered; and PhD trainees completed a self-administered questionnaire on motivating and challenging factors they may have experienced during their PhD training. RESULTS: Of the 640 PhD trainees enrolled in the health sciences since 2006, only 24 (3.8%) were in an HSSR field. None of the universities had a PhD training program focusing on HSSR. The 24 HSSR PhD trainees had trained in partnership with a university outside Africa. Top motivating factors for PhD training were: commitment of supervisors (67%), availability of scholarships (63%), and training attached to a research grant (25%). Top challenging factors were: procurement delays (44%), family commitments (38%), and poor Internet connection (35%). CONCLUSION: The number of HSSR PhD trainees is at the moment too small to enable a rapid accumulation of the required critical mass of locally trained HSSR professionals to drive the much needed health systems strengthening and innovations in this region. Curricula for advanced HSSR training are absent, exposing a serious training gap for HSSR in this region.

RESUMEN

Background: Antimicrobial resistance (AMR) which has been ascribed to be due to community carriage of antibiotic-resistant bacteria is highly prevalent in the WHO South-East Asia region. One of the major reasons for this is the misuse of antibiotics in animal farming practices and at the community level, which threatens both human and animal health. However, this problem of antibiotic misuse in poultry farms and in respective farmers is not well studied in countries like Pakistan. Methods: We conducted a cross-sectional study in rural Punjab to explore the current practices of antibiotic use in poultry and poultry farmers, associated factors, their healthcare-seeking behavior and biosecurity practices. Results: In the context of antibiotic use for poultry, 60% comprised of Colistin sulfate and Amoxicillin trihydrate whereas Colistin is considered as the last resort antibiotic. In addition, the significant consumption of antibiotics in poultry farms (60%) and poultry farmers (50%) was without prescription by either human health physicians or veterinarians. Most of the farms (85%) had no wastewater drainage system, which resulted in the direct shedding of poultry waste and antibiotic residue into the surrounding environment. The lack of farmers' education, professional farm training and farming experience were the most significant factors associated with antibiotic use and knowledge of AMR. Conclusion: Our study findings show that it is necessary for an integrated AMR policy with the inclusion of all poultry farmers to be educated, a mass awareness program to be undertaken and that strict antibiotic usage guidelines be available to them. Such initiatives are also important to ensure food safety and farm biosecurity practices.

RESUMEN

INTRODUCTION: Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool when taken as prescribed. However, suboptimal use may challenge its real-life impact. To support female sex workers in their efforts to prevent themselves from HIV, it is essential to identify factors that contribute to early disengagement from PrEP care. In this study, we aimed to estimate the risk of early disengagement from PrEP services among female sex workers in Tanzania and associated factors using a socioecological model as a guiding framework. METHODS: The study was conducted as part of a pragmatic mHealth trial for PrEP roll-out in Dar es Salaam in 2021. We estimated the risk of early disengagement, defined as not presenting for the first follow-up visit (within 56 days of enrolment), and its associations with individual, social, behavioural and structural factors (age, self-perceived HIV risk, mental distress, harmful alcohol use, condom use, number of sex work clients, female sex worker stigma and mobility) using multivariable logistic regression models, with marginal standardisation to obtain adjusted relative risks (aRR). RESULTS: Of the 470 female sex workers enrolled in the study, 340 (74.6%) did not attend the first follow-up visit (disengaged). Mental distress (aRR=1.14; 95% CI 1.01 to 1.27) was associated with increased risk of disengagement. Participants who reported a higher number of clients per month (10-29 partners: aRR=0.87; 95% CI 0.76 to 0.98 and ≥30 partners: aRR=0.80; 95% CI 0.68 to 0.91) and older participants (≥35 years) (RR=0.75; 95% CI 0.56 to 0.95) had a lower risk of disengagement. CONCLUSIONS AND RECOMMENDATIONS: Early disengagement with the PrEP programme was high. Mental distress, younger age and having fewer clients were risk factors for disengagement. We argue that PrEP programmes could benefit from including mental health screening and treatment, as well as directing attention to younger sex workers and those reporting fewer clients.

RESUMEN

Harmful alcohol use is an important risk factor for premature mortality and morbidity and associated with increased HIV risk and lower uptake of and adherence to HIV interventions. This study aimed to assess the extent of harmful alcohol use and associated socio-structural vulnerability factors among female sex workers in Dar es Salaam, Tanzania, a key population in the HIV epidemic. Data from a study of female sex workers initiating pre-exposure prophylaxis (PrEP) recruited through respondent driven sampling were used. We assessed harmful alcohol use with the Alcohol Use Disorders Identification Test (AUDIT) defined as having an AUDIT score ≥ 16. Associations between harmful alcohol use and socio-structural factors were assessed using logistic regression with marginal standardization. Of the 470 women recruited, more than one third (37.3%) had a drinking pattern suggestive of harmful alcohol use. Such use was independently associated with sex work-related mobility (aPR: 1.36, 95% CI: 1.11-1.61), arrest/incarceration (aPR: 1.55, 95% CI: 1.27-1.84) and gender-based violence (aPR: 1.31, 95% CI: 1.06-1.56). The high prevalence of harmful alcohol use and the interconnectedness with socio-structural factors indicate a need for a holistic programmatic approach to health for female sex workers. Programming should not solely direct attention to individual behavior but also include strategies aiming to address socio-structural vulnerabilities.

RESUMEN

Background: An increasing body of literature focuses on access to healthcare services for men who engage in sex with other men in Africa, but how healthcare workers conceive of this topic of healthcare workers' views on men's care has not been much studied. Drawing on qualitative research, this article explores healthcare providers' perspectives on access to HIV-related healthcare services among gender and sexuality diverse men in Tanzania. Methods: A qualitative study was conducted among healthcare workers in Dar es Salaam and Tanga, Tanzania in 2018/2019. Data collection entailed qualitative interviewing, focus group discussions and participant observation. A purposive sampling strategy was used to select study participants who varied with respect to age, education level, work experience, and the type and location of the facilities they worked in. A total of 88 participants took part in the study. Results: This paper describes four different discourses that were identified among healthcare workers with respect to their perception of access to healthcare services for men who have sex with men. One held that access to healthcare was not a major problem, another that some same-sex attracted men did not utilize healthcare services although they were available to them, a third that some healthcare workers prevented these men from gaining access to healthcare and a fourth that healthcare for gender and sexual minority persons was made difficult by structural barriers. Conclusion: Although these are four rather different takes on the prevailing circumstances with respect to healthcare access for same-sex attracted men (SSAM), we suggest that they may all be "true" in the sense that they grasp and highlight different aspects of the same realities. More education is needed to healthcare providers to enable them accept SSAM who seek healthcare services and hence improve access to healthcare.

RESUMEN

BACKGROUND: Injuries contribute to morbidity and mortality in children. This study was carried out to describe the pattern of childhood injuries and associated risk factors in Dar es Salaam, Tanzania. METHODS: This case control study was conducted in six selected health facilities in Dar es Salaam, Tanzania. Data were collected using a structured questionnaire. Cases and controls were children below 18 years who had suffered injuries and those without injury associated condition respectively. RESULTS: A total of 492 cases and 492 controls were included in the study, falls (32%), burns (26%), Road Traffic Injuries (14%) and cuts (10%) were the major types of injuries identified. Younger parents/guardians {Adjusted odds ratio (AOR)= 1.4; 95% CI: 1.4 -3.6}, more than six people in the same house (AOR= 1.8; 95% CI: 1.3-2.6), more than three children in the house {AOR= 1.4; 95% CI (1.0-2.0)}, absence of parent/guardian at time of injury occurrence (AOR= 1.6; 95% CI: 1.1-2.3), middle socio-economic (AOR=1.6; 95%CI: 1.1-2.4) and low socio-economic status (AOR= 1.5; 95% CI: 1.0-2.1) were independent risk factors for childhood injury. CONCLUSION: Falls, burns and road traffic injuries were the main injury types in this study. Inadequate supervision, overcrowding, lower socio-economic status and low maternal age were significant risk factors for childhood injuries.

RESUMEN

INTRODUCTION: Monitoring resistance to first line Antiretroviral therapy (ART) is crucial in preventing accumulation of viral mutations following the implementation of the World Health Organization "treat all" initiative. We estimated the rate and predictors of virological treatment failure among adults living with HIV/AIDS in Dar es Salaam, Tanzania. METHODOLOGY: A retrospective cohort study involving adults aged 18 and above receiving first line ART in Dar as Salaam between 2016 and 2018 were recruited using multistage random sampling. Clinical and laboratory data were extracted from Care and Treatment Clinic database-2 (CTC2) followed by participant's interviews. Adjusted Cox-regression modelling was used to determine independent predictors of treatment failure. RESULTS: A total of 340 participants with mean age of 37 were recruited. Overall, 10.59% had virological failure and the rate of failure was 5.24 (95% CI:3.72; 7.27) per 100 person-months at risk with a median failure time of 18 months. Independent predictors of treatment failure were being a male (Adjusted hazard ratio (aHR) 2.78, 95%CI:1.16;6.63), having used treatment for less than two years (aHR, 12.48, 95%CI:3.64-22.71) and co-infection with Tuberculosis (aHR 2.1, 95%CI: 1.0;5.9). CONCLUSIONS: HIV virological failure occurs early during treatment in this population. Male clients, co-infected with Tuberculosis were at higher risk of ART failure within two years of treatment. Substantial stride has been made towards the achievement of the last UNAIDS 90 goal but tailored counseling and close monitoring of HIV/TB co-infected male clients following ART initiation could accelerate efforts to close the gap. Further studies on pre-treatment drug resistance mutations are called for.

RESUMEN

BACKGROUND: The burden of non-communicable diseases (NCDs), including cancer, in Africa is rising. Policymakers are charged with formulating evidence-based cancer control plans; however, there is a paucity of data on cancers generated from within Africa. As part of efforts to enhance cancer research training in East Africa, we performed a needs assessment and gap analysis of cancer-related research training resources in Tanzania. METHODS: A mixed-methods study to evaluate existing individual, institutional, and national resources supporting cancer research training in Tanzania was conducted. Qualitative data were collected using in-depth interviews while quantitative data were collected using self-administered questionnaires and online surveys. The study also included a desk-review of policy and guidelines related to NCD research and training. Study participants were selected to represent five groups: (i) policymakers; (ii) established researchers; (iii) research support personnel; (iv) faculty members in degree training programs; and (v) post-graduate trainees. RESULTS: Our results identified challenges in four thematic areas. First, there is a need for coordination and monitoring of the cancer research agenda at the national level. Second, both faculty and trainees identified the need for incorporation of rigorous training to improve research competencies. Third, sustained mentoring and institutional investment in development of mentorship resources is critical to empowering early career investigators. Finally, academic institutions can enhance research outputs by providing adequate research infrastructure, prioritizing protected time for research, and recognizing research accomplishments by trainees and faculty. CONCLUSIONS: As we look towards establishment of cancer research training programs in East Africa, investment in the development of rigorous research training, mentorship resources, and research infrastructure will be critical to empowering local health professionals to engage in cancer research activities.

RESUMEN

OBJECTIVES: To estimate HIV prevalence and associated risk factors among men who have sex with men (MSM) in Dar es Salaam, Tanzania following the implementation of the national comprehensive package of HIV interventions for key population (CHIP). DESIGN: A cross-sectional survey using respondent-driven sampling. SETTING: Dar es Salaam, Tanzania's largest city. PARTICIPANTS: Men who occasionally or regularly have sex with another man, aged 18 years and above and living in Dar es Salaam city at least 6 months preceding the study. PRIMARY OUTCOME MEASURE: HIV prevalence was the primary outcome. Independent risk factors for HIV infection were examined using weighted logistics regression modelling. RESULTS: A total of 777 MSM with a mean age of 26 years took part in the study. The weighted HIV prevalence was 8.3% (95% CI: 6.3%-10.9%) as compared with 22.3% (95% CI: 18.7%-26.4%) observed in a similar survey in 2014. Half of the participants had had sex with more than two partners in the month preceding the survey. Among those who had engaged in transactional sex, 80% had used a condom during last anal sex with a paying partner. Participants aged 25 and above had four times higher odds of being infected than those aged 15-19 years. HIV infection was associated with multiple sexual partnerships (adjusted OR/AOR, 3.0; 95% CI: 1.8-12.0), not having used condom during last sex with non-paying partner (AOR, 4.1; 95% CI: 1.4-7.8) and ever having engaged in group sex (AOR, 3.4; 95% CI: 1.7-3.6). CONCLUSION: HIV prevalence among MSM in Dar es Salaam has decreased by more than a half over the past 5 years, coinciding with implementation of the CHIP. It is nonetheless two times as high as that of men in the general population. To achieve the 2030 goal, behavioural change interventions and roll out of new intervention measures such as pre-exposure prophylaxis are urgently needed.
