RESUMEN
BACKGROUND: The absence of high-quality comprehensive civil registration and vital statistics systems across many settings in Africa has led to little empirical data on causes of death in the region. We aimed to use verbal autopsy data to provide comparative, population-based estimates of cause-specific mortality among adolescents and adults in eastern and southern Africa. METHODS: In this surveillance study, we harmonised verbal autopsy and residency data from nine health and demographic surveillance system (HDSS) sites in Kenya, Malawi, Tanzania, South Africa, Uganda, and Zimbabwe, each with variable coverage from Jan 1, 1995, to Dec 31, 2019. We included all deaths to adolescents and adults aged 12 or over that were residents of the study sites and had a verbal autopsy conducted. InSilicoVA, a probabilistic model, was used to assign cause of death on the basis of the signs and symptoms reported in the verbal autopsy. Levels and trends in all-cause and cause-specific mortality rates and cause-specific mortality fractions were calculated, stratified by HDSS site, sex, age, and calendar periods. FINDINGS: 52â484 deaths and 5â157â802 person-years were reported among 1â071â913 individuals across the nine sites during the study period. 47â961 (91·4%) deaths had a verbal autopsy, of which 46â570 (97·1%) were assigned a cause of death. All-cause mortality generally decreased across the HDSS sites during this period, particularly for adults aged 20-59 years. In many of the HDSS sites, these decreases were driven by reductions in HIV and tuberculosis-related deaths. In 2010-14, the top causes of death were: road traffic accidents, HIV or tuberculosis, and meningitis or sepsis in adolescents (12-19 years); HIV or tuberculosis in adults aged 20-59 years; and neoplasms and cardiovascular disease in adults aged 60 years and older. There was greater between-HDSS and between-sex variation in causes of death for adolescents compared with adults. INTERPRETATION: This study shows progress in reducing mortality across eastern and southern Africa but also highlights age, sex, within-HDSS, and between-HDSS differences in causes of adolescent and adult deaths. These findings highlight the importance of detailed local data to inform health needs to ensure continued improvements in survival.

Background: The severity of Severe Acute Respiratory Syndrome Coronavirus 2 infection varies with age and time. Here, we quantify how age-specific risks of hospitalization, intensive care unit (ICU) admission, and death upon infection changed from February 2020 to June 2021 in the Netherlands. Methods: A series of large representative serology surveys allowed us to estimate age-specific numbers of infections in three epidemic periods (late-February 2020 to mid-June 2020, mid-June 2020 to mid-February 2021, and mid-February 2021 to late-June 2021). We accounted for reinfections and breakthrough infections. Severity measures were obtained by combining infection numbers with age-specific numbers of hospitalization, ICU admission, and excess all-cause deaths. Results: There was an accelerating, almost exponential, increase in severity with age in each period. The rate of increase with age was the highest for death and the lowest for hospitalization. In late-February 2020 to mid-June 2020, the overall risk of hospitalization upon infection was 1.5% (95% confidence interval [CI] 1.3-1.8%), the risk of ICU admission was 0.36% (95% CI: 0.31-0.42%), and the risk of death was 1.2% (95% CI: 1.0-1.4%). The risk of hospitalization was significantly increased in mid-June 2020 to mid-February 2021, while the risk of ICU admission remained stable over time. The risk of death decreased over time, with a significant drop among ≥70-years-olds in mid-February 2021 to late-June 2021; COVID-19 vaccination started early January 2021. Conclusion: Whereas the increase in severity of Severe Acute Respiratory Syndrome Coronavirus 2 with age remained stable, the risk of death upon infection decreased over time. A significant drop in risk of death among elderly coincided with the introduction of COVID-19 vaccination.

Background: This study describes factors promoting child labour in small-scale gold mines in rural Tanzania, a pernicious problem despite the country's adoption of laws and regulations intended to curb it. Methods: Employing a phenomenological design, we collected qualitative data using focus group discussions and in-depth interviews to describe factors promoting children's engagement in small-scale gold mining activities in three districts in Tanzania. Data analysis applied constructs from the ecological system theory. Results: Child labour was reported to be common in the small-scale gold mines and abject household poverty was reported as the main factor pushing children to work in the mines because of their respective households' inability to provide for their basic needs. Other underlying factors stated included divorce and family disintegration and limited diversification of income-earning activities. The migratory nature of artisanal mining led some miner parents to not prioritize the education of their children. Furthermore, peer pressure and parental influence, especially of mothers, promoted entry into mining or reinforced its continuation. Early socialisation of children as future miners and lack of perspective and societal expectations of other life trajectories contributed to persistent child labour within mining communities. At the government level, the study participants mentioned poor reinforcement of mining regulations as another factor that legitimised child labour in the mines. Conclusion: Since factors promoting child labour in small-scale gold mines are multifaceted, efforts for its elimination require a multi-layered approach aimed at addressing the root-causes at the micro-, meso-, exo- and macro-level systems.
RESUMEN
Little is known about how CD4 and viral load testing have evolved following implementation of universal test and treat (UTT) in African settings. We reviewed World Health Organization (WHO) guidance from 2013 to 2018, and compared it against national HIV policies in Malawi, Tanzania and South Africa. Three surveys rounds were conducted in 2013, 2016 and 2017-2018 in 33 health facilities across the three settings to assess implementation of national policies on the use of biological markers. Qualitative interviews were conducted with 26 HIV policymakers or programme managers, 21 providers and 66 people living with HIV to explore understandings and experiences of these tests. Various factors influenced adoption and implementation of WHO guidance, including historical policies on CD4 counts, governance issues, supply chain challenges and funding mechanisms. Facility-level practices relating to the use of these tests often diverged from national policies. Patients and providers valued both tests, but did not always understand their roles. In addition to continued support for scaling-up viral load testing, renewed focus should be placed on the ongoing value of point-of-care CD4 tests in the UTT era, including its role in assessing disease progression and informing clinical management of cases to reduce HIV-related mortality.

Effective implementation of policies for expanding antiretroviral therapy (ART) requires a well-trained and adequately staffed workforce. Changes in national HIV workforce policies, health facility practices, and provider experiences were examined in rural Malawi and Tanzania between 2013 and 2017. In both countries, task-shifting and task-sharing policies were explicit by 2013. In facilities, the cadre mix of providers varied by site and changed over time, with a higher and growing proportion of lower cadre staff in the Malawi site. In Malawi, the introduction of lay counsellors was perceived to have eased the workload of other providers, but lay counsellors reported inadequate support. Both countries had guidance on the minimum numbers of personnel required to deliver HIV services. However, patient loads per provider increased in both settings for HIV tests and visits by ART patients and were not met with corresponding increases in provider capacity in either setting. Providers reported this as a challenge. Although increasing patient numbers bodes well for achieving universal antiretroviral therapy coverage, the quality of care may be undermined by increased workloads and insufficient provider training. Task-shifting strategies may help address workload concerns, but require careful monitoring, supervision and mentoring to ensure effective implementation.

National HIV testing policies aim to increase the proportion of people living with HIV who know their status. National HIV testing policies were reviewed for each country from 2013 to 2018, and compared with WHO guidance. Three rounds of health facility surveys were conducted to assess facility level policy implementation in Karonga (Malawi), uMkhanyakude (South Africa), and Ifakara (Tanzania). A policy 'implementation' score was developed and applied to each facility by site for each round. Most HIV testing policies were explicit and aligned with WHO recommendations. Policies about service coverage, access, and quality of care were implemented in >80% of facilities per site and per round. However, linkage to care and the provision of outreach HIV testing for key populations were poorly implemented. The proportion of facilities reporting HIV test kit stock-outs in the past year reduced over the study period in all sites, but still occurred in ≥17% of facilities per site by 2017. The implementation score improved over time in Karonga and Ifakara and declined slightly in uMkhanyakude. Efforts are needed to address HIV test kit stock-outs and to improve linkage to care among people testing positive in order to reach the 90-90-90 targets.

Although integration of HIV and maternal health services is recommended by the World Health Organization, evidence to guide implementation is limited. We describe facility-level implementation of policies for integrating HIV care within maternal health services and explore experiences of service users and providers in rural Tanzania (Ifakara), South Africa (uMkhanyakude) and Malawi (Karonga). Policy in all countries included HIV testing during antenatal care (ANC), same-day antiretroviral therapy (ART) initiation for HIV-positive pregnant women, and postpartum referral to ART clinics, between six weeks (Malawi, South Africa) and two years after delivery (Tanzania). All facilities offered HIV testing within ANC, most commonly during the first visit. Although most women were comfortable with HIV testing, some felt that opting out would lead to sub-standard services. Some facilities conducted group post-test counselling for HIV-negative women, raising concerns of unintended HIV status disclosure. ART initiation was offered on the same day, the same room as an HIV diagnosis in >90% of facilities. Women's worries around postpartum referral included having unknown providers, insufficient privacy and queues. Adoption and implementation of policies on integrated HIV and maternal health services varied across settings. Patients' experiences of these policies may influence uptake and retention in care.

BACKGROUND: Trained community workers (CWs) successfully deliver health and social services, especially due to greater community acceptance. Orphans and vulnerable children (OVC) and their caregivers (CG) often need support from several sectors. We identified CW, program and referral characteristics that were associated with success of referrals provided to OVC and their CG in Tanzania in a cross-sectoral bi-directional referral system. METHODS: Data for this secondary analysis come from the first two years (2017-2018) of the USAID funded Kizazi Kipya project. Referral success was defined as feedback and service received within 90 days post-referral provision. We analyzed factors that are associated with the referral success of HIV related, education, nutrition, parenting, household economic strengthening, and child protection services among OVC and CG, using generalized estimating equations. RESULTS: During the study period, 19,502 CWs in 68 councils provided 146,996 referrals to 132,640 beneficiaries. OVC had much lower referral success for HIV related services (48.1%) than CG (81.2%). Adjusted for other covariates, CW age (26-49 versus 18-25 years, for OVC aOR = 0.83, 95%CI (0.78, 0.87) and CW gender (males versus females, for OVC aOR = 1.12, 95%CI (1.08, 1.16); CG aOR = 0.84, 95%CI (0.78, 0.90)) were associated with referral success. CWs who had worked > 1 year in the project (aOR = 1.52, 95%CI 1.46, 1.58) and those with previous work experience as CW (aOR = 1.57, 95%CI (1.42, 1.74) more successfully referred OVC. Referrals provided to OVC for all other services were more successful compared to HIV referrals, with aORs ranging from 2.99 to 7.22. Longer project duration in the district council was associated with increased referral success for OVC (aOR = 1.16 per month 95%CI 1.15,1.17), but decreased for CG (aOR = 0.96, 95%CI 0.94, 0.97). Referral success was higher for OVC and CGs with multiple (versus single) referrals provided within the past 30 days (aOR = 1.28 95%CI 1.21, 1.36) and (aOR = 1.17, 95%CI (1.06, 1.30)) respectively. CONCLUSION: CW characteristics, referral type and project maturity had different and often contrasting associations with referral success for OVC versus for CG. These findings could help policymakers decide on the recruitment and allocation of CWs in community based multi-sectoral intervention programs to improve referral successes especially for OVC.

OBJECTIVE: To assess adoption of World Health Organization (WHO) guidance into national policies for prevention of mother-to-child transmission (PMTCT) of human immunodeficiency virus (HIV) and to monitor implementation of guidelines at facility level in rural Malawi, South Africa and the United Republic of Tanzania. METHODS: We summarized national PMTCT policies and WHO guidance for 15 indicators across the cascades of maternal and infant care over 2013-2016. Two survey rounds were conducted (2013-2015 and 2015-2016) in 46 health facilities serving five health and demographic surveillance system populations. We administered structured questionnaires to facility managers to describe service delivery. We report the proportions of facilities implementing each indicator and the frequency and durations of stock-outs of supplies, by site and survey round. FINDINGS: In all countries, national policies influencing the maternal and infant PMTCT cascade of care aligned with WHO guidelines by 2016; most inter-country policy variations concerned linkage to routine HIV care. The proportion of facilities delivering post-test counselling, same-day antiretroviral therapy (ART) initiation, antenatal care and ART provision in the same building, and Option B+ increased or remained at 100% in all sites. Progress in implementing policies on infant diagnosis and treatment varied across sites. Stock-outs of HIV test kits or antiretroviral drugs in the past year declined overall, but were reported by at least one facility per site in both rounds. CONCLUSION: Progress has been made in implementing PMTCT policy in these settings. However, persistent gaps across the infant cascade of care and supply-chain challenges, risk undermining infant HIV elimination goals.

BACKGROUND: Extramarital sex is a potential driver of human immunodeficiency virus (HIV) transmission for long-term couples in sub-Saharan Africa. It is increasingly recognized that preventing sexual risk behaviours requires an understanding and adjustment of sexual relationship factors beyond the individual level. We investigated the association between extramarital affairs and HIV status, factors associated with extramarital affairs, and created insights in the context and pathways for married men and women in rural Tanzania who engage in extramarital affairs. METHODS: A cross-sectional sequential explanatory mixed method design was employed. The WHO-Social determinants of health perspective guided the study. Using logistic regression, we analysed the MZIMA project community surveillance representative sample of 3884 married partners aged 15+ residing in Ifakara town, Tanzania (2012-2013). Multinomial logistic regression analysis established the relative risk ratio (RRR) of different social and economic factors with lifetime (proxy) and recent (12 months prior to survey) extramarital affairs. Logistic regression analysis determined the association between extramarital affairs and HIV status. Semi-structured interviews and focus group discussions explored the quantitative findings, capturing the experiences and norms regarding extramarital affairs. RESULTS: We found a significant association between lifetime (proxy) extramarital affairs and HIV infection among women only. The RRR of having extramarital affairs (lifetime proxy) was significantly higher among Village Community Bank (VICOBA) members, the re-married, consumers of alcohol, those from southern regions, non-Muslims, and those with older age. In the case of recent extramarital affairs (12 months prior to survey), associations were significant for the same variables except for religion, having an income was also associated with the outcome. Qualitative narratives reflected that, desire to prove manhood (masculinity) supported by societal normative beliefs such as; 'it is not realistic for a man to stay without extramarital partner' and religious beliefs; 'a man shall dominate a woman' encouraged men's extramarital affairs. For women, striving for financial autonomy, obligations to pay back debts borrowed from several VICOBA, and limited support from their husbands encouraged their engagement in extramarital affairs. Low relationship quality (conflict and sexual dissatisfaction) were reported to encourage both men and women's extramarital affairs. CONCLUSIONS: The findings show that the link between extramarital affairs and HIV has a gender dimension in which women are more likely to acquire HIV through extramarital affairs (case of recent extramarital affairs (12 months prior to survey). Future programs seeking to address risk sexual behaviors in Tanzanian marriages can consider context-sensitive interventions which address aspects beyond 'individual risk' and women's financial uncertainties, and include couple's relationship quality, excessive alcohol behaviors, normative masculinity ideology and societal norms, that encourage women's economic dependence and men's engagement in multiple sexual partnerships. Microfinance projects (e.g. VICOBA) could be a platform for gender-transformative approaches, combining economic empowerment and HIV risk protection strategies.

Physical activity is essential for healthy aging. Evidence suggests that vigorous-intensity physical activity (VPA) may be more beneficial than moderate-intensity physical activity (MPA). We examined physical activity levels (MPA, VPA and total physical activity), and their socio-demographic determinants in 2311 participants (15â»93 years; 68% women) of the MZIMA Open Community Cohort, who had complete relevant data. Physical activity levels were estimated in minutes per week across three domains—work, leisure and transport. We created three outcome variables: low MPA (<150 min per week of MPA), low VPA (<75 min per week of VPA) and insufficient physical activity (IPA: <150 min per week of total physical activity) and applied sample-weighted multivariable logistic regression to assess associations with potential socio-demographic determinants. Prevalence of IPA, low MPA and low VPA were 25%, 26% and 65% respectively. IPA and low MPA were correlated (Spearman R = 0.98; p < 0.001). Work, leisure and transport contributed 54%, 25% and 21% to total physical activity respectively. IPA and low VPA were significantly associated with female sex, lower education, non-manual occupation and frequent fruit consumption. We observed significant differences by sex (Pheterogeneity < 0.001), on the associations between education and IPA, and between age, occupation and low VPA. In conclusion, low levels of VPA, which were more pronounced in women, support the monitoring and promotion of VPA alongside overall physical activity. Leisure-related activities should also be promoted towards gains in vigorous-intensity and total physical activity in this setting.

BACKGROUND: Global evidence shows that sexually transmitted infections (STIs) prevalence and sexual risk behaviours are high among youth, and knowledge about STIs is low. In Tanzania, there is limited recent evidence regarding these issues. The aim of this study was to describe the health seeking behaviour of youth reporting STI symptoms in semi-rural Tanzania and to evaluate the association of socio-demographic characteristics, STI knowledge and sexual risk behaviour with STI symptom reporting. METHODS: This was a cross-sectional study involving 2251 sexually experienced youth (15-24 years), who participated in a larger baseline survey of a cohort within Ifakara town. Interview data were electronically collected by trained field workers. Logistic regression analysis was used to identify factors that influence the risk of reporting STI symptoms within the past year, using Stata 12.1. RESULTS: The prevalence of self-reported STI symptoms in the past year was 19.9%. Almost all of youth had heard of STIs and 32.7% of youth could mention at least one sign. 34.4% had sought care for their STI symptoms, the majority at private facilities. Only 20% of HIV-STI co-infected youth was aware of their HIV status. Youth with more knowledge of STI symptoms reported to have had symptoms more often (OR = 1.28; 95% CI 1.01-1.62), and those reporting having first sex at 16 or under were more likely to report STI symptoms than those who delayed to 17-19 years (OR 1.27; 95% CI 1.003-1.62). CONCLUSION: These findings highlight the need to improve the implementation of Adolescent Friendly Health Services available in Tanzania (especially in semi-rural areas). The inclusion of private facilities and pharmacies in AFHS scale-up would potentially raise the level of STI knowledge, lower the STI prevalence and reduce HIV incidence among youth.

A daily intake of 5 portions of fruit and vegetables (FV) is recommended for protection against non-communicable diseases (NCDs). Inadequate FV intake is a global problem but resource-poor countries like Tanzania are most deprived and constitute settings where little is known for informing public health interventions. This study aimed to describe the prevalence of inadequate FV intake, frequency of FV intake, portions of FV intake and their associations with socio-demographic/lifestyle factors in South-Eastern Tanzania. Data on FV dietary indicators, socio-demographic factors, smoking, alcohol and healthcare use were collected from 7953 participants (≥15 years) of the population-based MZIMA open community cohort (2012-2013). Multivariable logistic regression was used to examine associations between FV intake outcomes and their socio-demographic/lifestyle determinants. Most (82%) of the participants did not meet the recommended daily FV intake While only a fraction consumed fruits daily (15.5%), almost half consumed vegetables daily (44.2%). However, the median (IQR) number of vegetable portions consumed was lower (2(1)/person/day) than that for fruits (2(2)/person/day) People with higher education were more likely to consume fruits daily. Independent correlates of inadequate FV intake included young age, being male, low education, low-income occupations, low alcohol, high tobacco and low healthcare use. Public health interventions should target the socio-economically deprived and culturally-rooted preferences while prioritizing promotion of vegetable for most immediate gain in overall FV intake.

BACKGROUND: Understanding the implementation of 2013 World Health Organization (WHO) consolidated guidelines on the use of antiretroviral drugs for treating and preventing HIV infection at the facility level provides important lessons for the roll-out of future HIV policies. METHODS: A national policy review was conducted in six sub-Saharan African countries to map the inclusion of the 2013 WHO HIV treatment recommendations. Twenty indicators of policy adoption were selected to measure ART access (n = 12) and retention (n = 8). Two sequential cross-sectional surveys were conducted in facilities between 2013/2015 (round 1) and 2015/2016 (round 2) from ten health and demographic surveillance sites in Kenya, Malawi, South Africa, Tanzania, Uganda and Zimbabwe. Using standardised questionnaires, facility managers were interviewed. Descriptive analyses were used to assess the change in the proportion of facilities that implemented these policy indicators between rounds. RESULTS: Although, expansion of ART access was explicitly stated in all countries' policies, most lacked policies that enhanced retention. Overall, 145 facilities were included in both rounds. The proportion of facilities that initiated ART at CD4 counts of 500 or less cells/µL increased between round 1 and 2 from 12 to 68%, and facilities initiating patients on 2013 WHO recommended ART regimen increased from 42 to 87%. There were no changes in the proportion of facilities reporting stock-outs of first-line ART in the past year (18 to 11%) nor in the provision of three-month supply of ART (43 to 38%). None of the facilities provided community-based ART delivery. CONCLUSION: The increase in ART initiation CD4 threshold in most countries, and substantial improvements made in the provision of WHO recommended first-line ART regimens demonstrates that rapid adoption of WHO recommendations is possible. However, improved logistics and resources and/or changes in policy are required to further minimise ART stock-outs and allow lay cadres to dispense ART in the community. Increased efforts are needed to offer longer durations between clinic visits, a strategy purported to improve retention. These changes will be important as countries move to implement the revised 2015 WHO guidelines to initiate all HIV positive people onto ART regardless of their immune status.

BACKGROUND: Tanzania is doubly burdened with both non-communicable and infectious diseases, but information on how Tanzanians experience the co-existence of these conditions is limited. Using Kleinman's eight prompting questions the study synthesizes explanatory models from patients to describe common illness experiences of diabetes in a rural setting where malaria is the predominant health threat. METHODS: We conducted 17 focus group discussions with adult members of the general community, diabetes patients, neighbours and relatives of diabetes patients to gain insight into shared experiences. To gain in-depth understanding of the individual illness experiences, we conducted 41 in-depth interviews with malaria or diabetes patients and family members of diabetes patients. The analysis followed grounded theory principles and the illness experiences were derived from the emerging themes. RESULTS: The illness experiences showed that malaria and diabetes are both perceived to be severe and fatal conditions, but over the years people have learned to live with malaria and the condition is relatively manageable compared with diabetes. In contrast, diabetes was perceived as a relatively new disease, with serious life-long consequences. Uncertainty, fear of those consequences, and the increased risk for severe malaria and other illnesses impacted diabetes patients and their families' illness experiences. Unpredictable ailments and loss of consciousness, memory, libido, and functional incapability were common problems reported by diabetes patients. These problems had an effect on their psychological and emotional health and limited their social life. Direct and indirect costs of illness pushed individuals and their families further into poverty and were more pronounced for diabetes patients. CONCLUSION: The illness experiences revealed both malaria and diabetes as distressing conditions, however, diabetes showed a higher level of stress because of its chronicity. Strategies for supporting social, emotional, and psychological well-being that build on the patient accounts are likely to improve illness experiences and quality of life for the chronically ill patient.

Most HIV research in Sub-Saharan Africa (SSA) ignores persons aged 50 years and above, though a few studies have reported a high HIV prevalence among older people. This study aimed to estimate socio-demographic inequalities in HIV testing behaviour and HIV prevalence among adults aged 50+ years, living in Ifakara town, Tanzania. This cross-sectional study used data from the baseline measurement of the Ifakara MZIMA cohort study in 2012/13. Consenting participants were interviewed and tested for HIV. Associations between HIV testing behaviour and HIV prevalence with socio-demographic indicators were explored with multivariable logistic regression. Among the 1643 adults 50+ years included in the study, HIV prevalence and the HIV testing rate (ever tested) were 6% and 11.4% respectively. The HIV testing rate was lower for older people (aOR = 0.19 (95% CI 0.09-0.41 for 75+ versus 50-54 years); higher for those separated/divorced/widowed than those married (aOR = 1.46; 1.02-2.10); higher for "other Christians" than Muslims (aOR = 1.95; 1.06-3.58); and higher for primary (aOR = 1.54; 1.01-2.33) and secondary (aOR = 3.47; 2.11-5.70) school graduates than those without education. HIV prevalence was lower for older people (aOR = 0.27; 0.11-0.66 for 75+ versus 50-54); and for Catholics compared to Muslims (aOR = 0.54; 0.34-0.85).

Current HIV policies in Tanzania have adopted the three long-term impact results of zero new infections, zero HIV deaths and zero stigma and discrimination. Strategies to reach these results include scaling-up HIV Testing and Counselling (HTC); Preventing Mother-To-Child Transmission (PMTCT); and strengthening Care and Treatment Clinic (CTC) services. Previous studies showed that HIV policy and guideline recommendations were not always implemented in rural South Tanzania. This study aims to identify the determinants of HIV guideline implementation. A qualitative study of 23 semi-structured interviews with facility in-charges; healthcare workers; district, regional and national HIV coordinators was conducted. Five health facilities were purposively selected by level, ownership and proximity to district headquarters. Interviews were analysed according to Fleuren's five determinants of innovation uptake related to: strategies used in guideline development and dissemination; guideline characteristics; the guideline implementing organization; guideline users; and the socio-cultural and regulatory context. None of the facilities had the HTC national guideline document. Non-involvement of providers in revisions and weak planning for guideline dissemination impeded their implementation. Lengthy guidelines and those written in English were under-used, and activities perceived to be complicated, like WHO-staging, were avoided. Availability of staff and lack of supplies like test kits and medication impeded implementation. Collaboration between facilities enhanced implementation, as did peer-support among providers. Provider characteristics including education level, knowledge of, and commitment to the guideline influenced implementation. According to providers, determinants of clients' service use included gender norms, stigma, trust and perceived benefits. The regulatory context prohibited private hospitals from buying HIV supplies. Being tools for bringing policies to practice, national guidelines are crucial in the efforts towards the three zeros. Strategies to improve providers' adherence to guidelines should include development of clearer guideline dissemination plans, strengthening of the health system, and possibly addressing of provider-perceived patient-level barriers to utilizing HIV services.

Diabetes prevalence in Tanzania was estimated at 9.1% in 2012 among adults aged 24-65 years - higher than the HIV prevalence in the general population at that time. Health systems in lower- and middle-income countries are not designed for chronic health care, yet the rising burden of non-communicable diseases such as diabetes demands chronic care services. To inform policies on diabetes care, we conducted a study on the health services in place to diagnose, treat and care for diabetes patients in rural Tanzania. The study was an exploratory and descriptive study involving qualitative methods (in-depth interviews, observations and document reviews) and was conducted in a rural district in Tanzania. Fifteen health providers in four health facilities at different levels of the health care system were interviewed. The health care organization elements of the Innovative Care for Chronic Conditions (ICCC) framework were used to guide assessment of the diabetes services in the district. We found that diabetes care in this district was centralized at the referral and district facilities, with unreliable supply of necessary commodities for diabetes care and health providers who had some knowledge of what was expected of them but felt ill-prepared for diabetes care. Facility and district level guidance was lacking and the continuity of care was broken within and between facilities. The HMIS could not produce reliable data on diabetes. Support for self-management to patients and their families was weak at all levels. In conclusion, the rural district we studied did not provide diabetes care close to the patients. Guidance on diabetes service provision and human resource management need strengthening and policies related to task-shifting need adjustment to improve quality of service provision for diabetes patients in rural settings.

BACKGROUND: Behavioral change approaches for human immunodeficiency virus (HIV) prevention in Tanzania encourage married partners to observe safe sex practices (condom use, avoidance of, or safe sex with multiple partners). To implement this advice, partners need to communicate with each other about safer sex, which is often challenging. Although social-structural factors are crucial in understanding sexual behavior, only a few studies focus on understanding safer sex dialogue in a broader social context. DESIGN: Drawing on the WHO-Commission on the Social Determinants of Health (WHO-CSDH) framework, this study explored key social-structural constructs for studying health in the context of improving safer sex dialogue between polygamous and monogamous partners. Twenty-four in-depth interviews (IDIs) and six focus group discussions (FGDs) with 38 men and women aged 18-60 years were conducted in Ifakara town located in Kilombero district, Tanzania. The study was nested within the community health surveillance project MZIMA (Kiswahili: 'being healthy'). Partners' experiences of safer sex dialogue in polygamous and monogamous relations were investigated and the challenges to safer sex dialogue explored. RESULTS: The study revealed that open safer sex dialogue in marriage is limited and challenged by social norms about marriage (a view that safer sex dialogue imply that partners are 'not really' married); marital status (a belief that safer sex dialogue is not practical in polygamous marriages, the elder wife should be exempted from the dialogue since she is at lower risk of engaging in extramarital affairs); relationship quality (marital conflicts, extramarital affairs, trust, and sexual dissatisfaction); and gender power relations (the notion that females' initiative to discuss condom use and HIV couple counseling and testing may lead to conflict or divorce). CONCLUSIONS: Implementing safer sex practices requires interventions beyond promotion messages. HIV prevention interventions in Tanzania should be carefully adapted to the local context including respective social norms, gender systems, marital context and relationship uncertainties as aspects that facilitate or hinder safer sex dialogue between partners. The WHO-CSDH framework could be strengthened by explicitly integrating relationship quality, marital status, and social norms as additional determinants of health.
RESUMEN
BACKGROUND: The high prevalence of chronic diseases in Tanzania is putting a strain on the already stretched health care services, patients and their families. This study sought to find out how health care for diabetes and HIV is perceived, practiced and experienced by patients and family caregivers, to inform strategies to improve continuity of care. METHODS: Thirty two in-depth interviews were conducted among 19 patients (10 HIV, 9 diabetes) and 13 family caregivers (6 HIV, 7 diabetes). Diabetes patients and caregivers were accessed through one referral facility. HIV patients and caregivers were accessed through HIV clinics at the district hospital, one health centre and one dispensary respectively. The innovative care for chronic conditions framework informed the study design. Data was analysed with the help of Nvivo 10. RESULTS: Three major themes emerged; preparedness and practices in care, health care at health facilities and community support in care for HIV and diabetes. In preparedness and practices, HIV patients and caregivers knew more about aspects of HIV than did diabetes patients and caregivers on diabetes aspects. Continued education on care for the conditions was better structured for HIV than diabetes. On care at facilities, HIV and diabetes patients reported that they appreciated familiarity with providers, warm reception, gentle correction of mistakes and privacy during care. HIV services were free of charge at all levels. Costs involved in seeking services resulted in some diabetes patients to not keep appointments. There was limited community support for care of diabetes patients. Community support for HIV care was through community health workers, patient groups, and village leaders. CONCLUSION: Diabetes and HIV have socio-cultural and economic implications for patients and their families. The HIV programme is successfully using decentralization of health services, task shifting and CHWs to address these implications. For diabetes and NCDs, decentralization and task shifting are also important and, strengthening of community involvement is warranted for continuity of care and patient centeredness in care. While considering differences between HIV and diabetes, we have shown that Tanzania's rich experiences in community involvement in health can be leveraged for care and treatment of diabetes and other NCDs.
