Editorial: Fifty years of health services in Tanzania: What next?

Before independence in 1961, Tanzania was a Germany colony (1889-1916) and later British Protectorate (1916-1961). During the 72 year period, the western medical services targeted foreigners working for the colonial governments. After independence, the government has expanded the health services with a vision to improve the health and well being of all Tanzanians with a focus on those most at risk, and to encourage the health system to be more responsive to the needs of the people. The policy mission is to facilitate the provision of equitable, quality and affordable basic health services, which are gender sensitive and sustainable, delivered for the achievement of improved health status. This issue of the Tanzania Journal of Health Research is dedicated for the 50th Anniversary of the Tanzania independence. It includes a number of reviews focussed on different aspects of health, both communicable and non-communicable diseases. The reviews focus on a number of health problems that faced Tanzania during the past fifty years. Challenges to meet the national and global development goals are discussed in line with the changing epidemiological patterns for both communicable and non-communicable diseases

Food insecurity and coping strategies among people living with HIV in Dar es Salaam, Tanzania

Food insecurity and malnutrition seriously impedes efforts to control HIV/AIDS in resource poor countries. This study was carried out to assess food security, and coping strategies among people living with HIV/AIDS (PLHIV) attending Care and Treatment Centre (CTC) in Dar es Salaam, Tanzania. A structured questionnaire was used to interview randomly selected adults (≥18 years) who were HIV positive who have just been eligible for anti-retroviral treatment (ART) in a CTC or one who has started ART but not more than four weeks has elapsed. A total of 446 (females=67.9%; males= 32.1%) people living with HIV/AIDS attending CTC were interviewed. About three quarters (73.1%) of the respondents were 25-44 years old and most (43.9%) were married. Two thirds (66.7%) of the respondents had primary school education. Seventy percent reported to have a regular income and 63.7% with a monthly income of less than US$154. More than half (52.2$154) (OR=0.10; 95%CI, 0.01–0.67). Reporting two or less meals increased the likelihood of food insecurity (OR=4.2; 95% CI1.7-9.8). Low frequency of meals was significantly more prevalent (18.6%) among those ≥45 years than among 35–44 years old respondents (6.7%) (P=0.04). Borrowing money (55.8%) and taking less preferred foods (53.3%) were the most common coping strategies. In conclusion, food insecurity is a significant problem among people living with HIV in Dar es Salaam which might significantly affect compliance to care and support. The study suggests that counselling of PLHIV before anti-retroviral treatment programmes should devise special strategies targeting those with low education, low income and low frequency of meals

Maternal health in fifty years of Tanzania independence: Challenges and opportunities of reducing maternal mortality

High rate of maternal death is one of the major public health concerns in Tanzania.  Most of maternal deaths are caused by factors attributed to pregnancy, childbirth and poor quality of health services. More than 80% of maternal deaths can be prevented if pregnant women access essential maternity care and assured of skilled attendance at childbirth as well as emergency obstetric care. The objective of this review was to analyse maternal mortality situation in Tanzania during the past 50 years and to identify efforts, challenges and opportunities of reducing it. This paper was written through desk review of key policy documents, technical reports, publications and available internet-based literature. From 1961 to 1990 maternal mortality ratio in Tanzania had been on a downward trend from 453 to 200 per 100,000 live births. However, from 1990’s there been an increasing trend to 578 per 100,000 live births. Current statistics indicate that maternal mortality ratio has dropped slightly in 2010 to 454 per 100,000 live births. Despite a high coverage (96%) in pregnant women who attend at least one antenatal clinic, only half of the women (51%) have access to skilled delivery. Coverage of emergence obstetric services is 64.5% and utilization of modern family planning method is 27%. Only about 13% of home deliveries access post natal check-up. Despite a number of efforts maternal mortality is still unacceptably high. Some of the efforts done  to reduce maternal mortality in Tanzania included the following initiatives: reproductive and child survival; increased skilled delivery; maternal death audit; coordination and integration of  different programs including maternal and child health services, family planning, malaria interventions, expanded program on immunization  and adolescent health and nutrition programmes. These initiatives are however challenged by inadequate access to maternal health care services. In order to considerably reduce maternal deaths some of recommended strategies include: (i) strengthening the health system to provide skilled attendance during child birth; (ii) upgrading rural health centres to provide emergency obstetric services; (iii) providing adolescent and male friendly family planning services; (iv) strengthening public–private partnership to ensure continuum of care; (v) supporting operational research to answer the immediate concerns of the health system; and (vi) strengthening community participation and women empowerment to take role of their own health and the family at large. In conclusion, maternal mortality ratio in Tanzania is unacceptably high and still very far from reaching the millennium development goals. Maternal health care services should focus on ensuring there is continuum of care through strengthening the health system; provision of good quality of health care in a well organized referral health system and operation research to support programme implementation

Challenges and opportunities in building health research capacity in Tanzania: a case of the National Institute for Medical Research

Capacity building is considered a priority for health research institutions in developing countries to achieve the Millennium Development Goals by 2015. However, in many countries including Tanzania, much emphasis has been directed towards human resources for health with the total exclusion of human resources for health research.  The objective of this study was to systematically investigate the capacity building process for the Tanzanian National Institute for Medical Research (NIMR) over a 30-year period and identify the challenges and opportunities in creating a critical mass of multi-disciplinary research scientists that is required for achieving the intended health benefits. A desk review of personnel database was conducted for information covering 1980-2009 on academic qualifications, training, research experience and research output. The current staff curriculum vitae (CV) were reviewed to gather information on researchers’ employment record, training, training support, area of expertise and scientific output. Interviews were conducted with a cross section of researchers on capacity development aspects using a self-administered questionnaire. In-depth interviews were also conducted with the current and former NIMR Management to seek information on capacity development challenges. A review was also done on staff personal files, annual reports, strategic plans and other occasional documents. A total of 163 CV were assessed; of these, 76.7% (125) were for Research Scientists (RS), 20.9% (34) Laboratory Technologists (LT) and 2.4% (4) for System Analysts. The Institute had 13 research scientists upon its establishment. Since 1980, NIMR has recruited a total of 185 Research Scientists. By 2009, NIMR had a total scientific workforce of 170 staff (RS= 82.4%; LT= 17.6%). Of the 140 RSs, 37 (26.4%) were first degree; 77 (55.5%) second degree while 26 (18.6%) were PhD degree holders. Of the total of 78 researchers interviewed, 55 (70.5%) indicated to have accessed postgraduate training through their personal efforts and 23 through institutional arrangement. Sixty (77%) respondents were satisfied with their tenure at NIMR. Seventy (89%) indicated that they had not at any point considered leaving NIMR. Most (79%) research scientists were recruited while holding a first degree, a few (17%) with second degree while only one (0.7%) holding a PhD degree. NIMR has experienced a research scientist attrition rate of 17.5%. Staff retention factors included availability of training opportunities; passion for conducting research; and good career prospects. Despite having a training programme, the institute has never at any moment been able to hold its own training resources. Being a public research institution, NIMR receives its core funding from the government of the United Republic of Tanzania. The bulk of the funding appears to be spent on personnel emoluments that take up to 85% (mean= 66%) of the allocated budget. In conclusion, the current NIMR’s research capacity building is dependent mainly on foreign funding and personal initiatives. There is an urgent need to increase local funding for capacity building and conduct of research. A programme should be put in place to ensure sustainability of the capacity building process

Stagnating maternal mortality in Tanzania: what went wrong and what can be done

Background: This paper presents and analyses the trend of maternal mortality ratio in Tanzania against major events, policy, economic and political decisions which may have influenced this trend. The impact of several initiatives related to Health Systems Strengthening are discussed and alternative strategies for effective maternal mortality reduction in Tanzania are proposed.Methods: We reviewed data and information published on maternal mortality and relevant political decisions, policies programmes and guidelines on maternal and new-born for Tanzania from 1990 to 2016. We examined the timeline of economic development, political decisions and other major events going back 5-10 years before the possible stagnation of maternal mortality decline.Results: This period coincides with the Health Sector Reforms which included among other things the introduction of user fees, reintroduction of private practice, staff retrenchment, widening inequalities and growing poverty. Health service factors include persistent low coverage and utilization of basic emergency obstetric care services. To address these gaps, we propose strengthening rights-based approaches in maternal health programming with political, financial and performance accountabilities at all levels. Introducing these will themselves help with improvement of the quality of care and address the issues of equity by reaching even the poorest households. We further propose application of process indicators to monitor maternal care services. Skilled care should be adopted as the single most important indicator for improving emergency obstetric care. There is need to review the legal and policy framework on task shifting to allow nurses to deliver the seven signal functions and Assistant Medical Officers to deliver Comprehensive Emergency Obstetric Care.Conclusion: We conclude that greater effort needs to be put in designing heath strengthening systems that address more the demand side of health systems strengthening as opposed to current efforts which are largely supply oriented

Impact of climate change on human health and health systems in Tanzania: a review

Climate change (CC) has a number of immediate and long-term impacts on the fundamental determinants of human health. A number of potential human health effects have been associated either directly or indirectly with global climate change. Vulnerability to the risks associated with CC may exacerbate ongoing socio-economic challenges. The objective of this review was to analyse the potential risk and vulnerability in the context of climate-sensitive human diseases and health system in Tanzania. Climate sensitive vector- and water-borne diseases and other health related problems and the policies on climate adaptation in Tanzania during the past 50 years are reviewed. The review has shown that a number of climate-associated infectious disease epidemics have been reported in various areas of the country; mostly being associated with increase in precipitation and temperature. Although, there is no single policy document that specifically addresses issues of CC in the country, the National Environmental Management Act of 1997 recognizes the importance of CC and calls for the government to put up measures to address the phenomenon. A number of strategies and action plans related to CC are also in place. These include the National Biodiversity Strategy and Action Plan, the National Action Programme, and the National Bio-safety Framework. The government has put in place a National Climate Change Steering Committee and the National Climate Change Technical Committee to oversee and guide the implementation of CC activities in the country. Recognizing the adverse impacts of natural disasters and calamities, the government established a Disaster Management Division under the Prime Minister’s Office. Epidemic Preparedness and Response Unit of the Ministry of Health and Social Welfare is responsible for emergency preparedness, mostly disease outbreaks. However, specific climate changes associated with human health issues are poorly addressed in the MoHSW strategies and the national health research priorities. In conclusion, CC threatens to slow, halt or reverses the progress the country has made or is making to achieve its national and millennium development goals. It is therefore important that Tanzania prepares itself to appropriately address CC impact on human health. It is equally important that policy makers and other stakeholders are engaged in a process to update and adapt priorities, mobilize resources and build interdisciplinary research and implementation capacity on climate change and its mitigation

Towards Malaria Elimination and its Implication for Vector Control, Disease Management and Livelihoods in Tanzania

Over the years, malaria has remained the number one cause of morbidity and mortality in Tanzania. Population based studies have indicated a decline in overall malaria prevalence among under-fives from 18.1% in 2008 to 9.7% in 2012. The decline of malaria infection has occurred in all geographical zones of the country. Malaria mortality and cumulative probability of deaths have also shown a marked decline from 2000 to 2010. During the same period, area specific studies in Muheza, Korogwe, Muleba and Mvomero have also reported a similar declining trend in malaria prevalence and incidence. The decline in malaria prevalence has been observed to coincide with a decline in transmission indices including anopheline mosquito densities. The decline in malaria prevalence has been attributed to a combination of factors including improved access to effective malaria treatment with artemisinin combination therapy and protection from mosquito bites by increased availability of insecticide treated bednets and indoor residual spraying. The objective of this paper was to review the changing landscape of malaria and its implication for disease management, vector control, and livelihoods in Tanzania. It seeks to examine the links within a broad framework that considers the different pathways given the multiplicity of interactions that can produce unexpected outcomes and trade-offs. Despite the remarkable decline in malaria burden, Tanzania is faced with a number of challenges. These include the development of resistance of malaria vectors to pyrethroids, changing mosquito behaviour and livelihood activities that increase mosquito productivity and exposure to mosquito bites. In addition, there are challenges related to health systems, community perceptions, community involvement and sustainability of funding to the national malaria control programme. This review indicates that malaria remains an important and challenging disease that illustrates the interactions among ecosystems, livelihoods, and health systems. Livelihoods and several sectoral development activities including construction, water resource development and agricultural practices contribute significantly to malaria mosquito productivity and transmission. Consequently, these situations require innovative and integrative re-thinking of the strategies to prevent and control malaria. In conclusion, to accelerate and sustain malaria control in Tanzania, the prevention strategies must go hand in hand with an intersectoral participation approach that takes into account ecosystems and livelihoods that have the potential to increase or decrease malaria transmission.\u

Prevalence and Predictors of HIV Infection among Under FiveYear Children Born to HIV Positive Mothers in Muheza District, North-Eastern Tanzania

Background: Human Immunodeficiency Virus (HIV) pandemic has become a serious public health concern worldwide. The prevalence of paediatric HIV infection is largely unknown in many countries in Sub-Saharan Africa (SSA). We aimed to determine the prevalence and predictors of HIV infection among under-5 years children in Muheza District, Tanzania.Methods: A facility-based study among mothers/guardians with their under-5 years children exposed to HIV infection was conducted from June 2015 to June 2016. Information on HIV status, socio-demographic and other family characteristics was collected using a structured questionnaire. Data analysis was performed using STATA version 13.0.Results: A total of 576 HIV-exposed under-5 years children were recruited together with their respective mothers/guardians. The HIV prevalence among under-5 years children was 10.6% (95% CI: 8.1-13.1%). The burden of HIV infection was observed among older children aged 25 to 59 months (AOR= 8.0, 95% CI 2.5-26.0) than in the younger children. There was a four-fold (AOR=3.9, 95% CI 1.7-9.1) risk of HIV infection among children born to mothers of unknown HIV status at conception than among children born to mothers with known HIV status. The odds of HIV infection were higher among children who were delivered from home (AOR=2.6, 95% CI 1.0-6.5), received mixed feeding (AOR=2.4, 95% CI 1.2-4.9), and those living far from a health facility (AOR=3.0, 95% CI 1.4-6.5).Conclusion: The prevalence of HIV among under-5 years children in Muheza is higher among older children. The high prevalence is associated with being born to mothers with unknown HIV status at conception, received mixed feeding, home delivery, and living far from the health facility. Campaigns that provide health educational massages addressing risk factors of HIV need to be emphasised in order to promote the control and prevention of HIV among children

Rift Valley fever potential mosquito vectors and their infection status in Ngorongoro District in northern Tanzania

Background: Rift Valley fever (RVF) is a mosquito-borne viral zoonotic disease. Rift Valley fever virus (RVFV) has been isolated from more than 40 species of mosquitoes from eight genera. This study was conducted to determine the abundance of potential mosquito vectors and their RVFV infection status in Ngorongoro District of northern Tanzania.Methods: Adult mosquitoes were collected outdoors using the CDC light traps baited with carbon dioxide in five randomly selected villages namely, Meshili, Malambo, Osinoni, Endulen and Nainokanoka. The study was carried out towards the end of rainy season in May 2013. The traps were set in proximity to potential breeding sites and cattle kraals. The collected mosquitoes were identified to genus and species using morphological keys. They were tested for RVFV RNA  using  real time reverse transcription-polymerase chain reaction (rRT-PCR).Results: A total of 2,094 adult mosquitoes belonging to three genera and nine species were collected. Most of them (87.5%) were collected in Meshili, followed by Malambo (8.2%) and Osinoni (4%) villages. No single mosquito was collected in Nainokanoka or Endulen. The nine species collected were Culex pipiens complex, Cx. antennatus, Cx. tigripes, Cx. annulioris, Cx. cinereus, Anopheles arabiensis, An. squamosus, An. pharoensis and Mansonia uniformis. No RVFV RNA was detected in the mosquito specimens.Conclusion: Various RVFV potential mosquito species were collected from the study villages. These mosquito vectors were heterogeneously distributed in the district suggesting a variation in RVF transmission risk in the study area

Regional Initiatives in Support of Surveillance in East Africa: The East Africa Integrated Disease Surveillance Network (EAIDSNet) Experience.

The East African Integrated Disease Surveillance Network (EAIDSNet) was formed in response to a growing frequency of cross-border malaria outbreaks in the 1990s and a growing recognition that fragmented disease interventions, coupled with weak laboratory capacity, were making it difficult to respond in a timely manner to the outbreaks of malaria and other infectious diseases. The East Africa Community (EAC) partner states, with financial support from the Rockefeller Foundation, established EAIDSNet in 2000 to develop and strengthen the communication channels necessary for integrated cross-border disease surveillance and control efforts. The objective of this paper is to review the regional EAIDSNet initiative and highlight achievements and challenges in its implementation. Major accomplishments of EAIDSNet include influencing the establishment of a Department of Health within the EAC Secretariat to support a regional health agenda; successfully completing a regional field simulation exercise in pandemic influenza preparedness; and piloting a web-based portal for linking animal and human health disease surveillance. The strategic direction of EAIDSNet was shaped, in part, by lessons learned following a visit to the more established Mekong Basin Disease Surveillance (MBDS) regional network. Looking to the future, EAIDSNet is collaborating with the East, Central and Southern Africa Health Community (ECSA-HC), EAC partner states, and the World Health Organization to implement the World Bank-funded East Africa Public Health Laboratory Networking Project (EAPHLNP). The network has also begun lobbying East African countries for funding to support EAIDSNet activities
