Equally able, but unequally accepted: Gender differentials and experiences of community health volunteers promoting maternal, newborn, and child health in Morogoro Region, Tanzania.

BACKGROUND: Despite emerging qualitative evidence of gendered community health worker (CHW) experience, few quantitative studies examine CHW gender differentials. The launch of a maternal, newborn, and child health (MNCH) CHW cadre in Morogoro Region, Tanzania enlisting both males and females as CHWs, provides an opportunity to examine potential gender differences in CHW knowledge, health promotion activities and client acceptability. METHODS: All CHWs who received training from the Integrated MNCH Program between December 2012 and July 2013 in five districts were surveyed and information on health promotion activities undertaken drawn from their registers. CHW socio-demographic characteristics, knowledge, and health promotion activities were analyzed through bi- and multivariate analyses. Composite scores generated across ten knowledge domains were used in ordered logistic regression models to estimate relationships between knowledge scores and predictor variables. Thematic analysis was also undertaken on 60 purposively sampled semi-structured interviews with CHWs, their supervisors, community leaders, and health committee members in 12 villages from three districts. RESULTS: Of all CHWs trained, 97% were interviewed (n = 228): 55% male and 45% female. No significant differences were observed in knowledge by gender after controlling for age, education, date of training, marital status, and assets. Differences in number of home visits and community health education meetings were also not significant by gender. With regards to acceptability, women were more likely to disclose pregnancies earlier to female CHWs, than male CHWs. Men were more comfortable discussing sexual and reproductive concerns with male, than female CHWs. In some cases, CHW home visits were viewed as potentially being for ulterior or adulterous motives, so trust by families had to be built. Respondents reported that working as female-male pairs helped to address some of these dynamics. CONCLUSIONS: Male and female CHWs in this study have largely similar knowledge and health promotion outputs, but challenges in acceptance of CHW counseling for reproductive health and home visits by unaccompanied CHWs varied by gender. Programs that pair male and female CHWs may potentially overcome gender issues in CHW acceptance, especially if they change gender norms rather than solely accommodate gender preferences.

Initial experiences and innovations in supervising community health workers for maternal, newborn, and child health in Morogoro region, Tanzania.

BACKGROUND: Supervision is meant to improve the performance and motivation of community health workers (CHWs). However, most evidence on supervision relates to facility health workers. The Integrated Maternal, Newborn, and Child Health (MNCH) Program in Morogoro region, Tanzania, implemented a CHW pilot with a cascade supervision model where facility health workers were trained in supportive supervision for volunteer CHWs, supported by regional and district staff, and with village leaders to further support CHWs. We examine the initial experiences of CHWs, their supervisors, and village leaders to understand the strengths and challenges of such a supervision model for CHWs. METHODS: Quantitative and qualitative data were collected concurrently from CHWs, supervisors, and village leaders. A survey was administered to 228 (96%) of the CHWs in the Integrated MNCH Program and semi-structured interviews were conducted with 15 CHWs, 8 supervisors, and 15 village leaders purposefully sampled to represent different actor perspectives from health centre catchment villages in Morogoro region. Descriptive statistics analysed the frequency and content of CHW supervision, while thematic content analysis explored CHW, supervisor, and village leader experiences with CHW supervision. RESULTS: CHWs meet with their facility-based supervisors an average of 1.2 times per month. CHWs value supervision and appreciate the sense of legitimacy that arises when supervisors visit them in their village. Village leaders and district staff are engaged and committed to supporting CHWs. Despite these successes, facility-based supervisors visit CHWs in their village an average of only once every 2.8 months, CHWs and supervisors still see supervision primarily as an opportunity to check reports, and meetings with district staff are infrequent and not well scheduled. CONCLUSIONS: Supervision of CHWs could be strengthened by streamlining supervision protocols to focus less on report checking and more on problem solving and skills development. Facility health workers, while important for technical oversight, may not be the best mentors for certain tasks such as community relationship-building. We suggest further exploring CHW supervision innovations, such as an enhanced role for community actors, who may be more suitable to support CHWs engaged primarily in health promotion than scarce and over-worked facility health workers.

Motivation and satisfaction among community health workers in Morogoro Region, Tanzania: nuanced needs and varied ambitions.

BACKGROUND: In 2012, the Ministry of Health and Social Welfare (MOHSW), Tanzania, approved national guidelines and training materials for community health workers (CHWs) in integrated maternal, newborn and child health (Integrated MNCH), with CHWs trained and deployed across five districts of Morogoro Region soon after. To inform future scale up, this study assessed motivation and satisfaction among these CHWs. METHODS: A survey of all CHWs trained by the Integrated MNCH Programme was conducted in the last quarter of 2013. Motivation and satisfaction were assessed using a five-point Likert scale with 29 and 27 items based on a literature review and discussions with CHW programme stakeholders. Exploratory factor analysis was conducted to identify motivation and satisfaction determinants. RESULTS: Out of 238 eligible CHWs, 96 % were included in the study. Findings showed that respondents were motivated to become CHWs due to altruism (work on MNCH, desire to serve God, work hard) and intrinsic needs (help community, improve health, pride) than due to external stimuli (monetary incentives, skill utilization, community respect or hope for employment). CHWs were satisfied by relationships with health workers and communities, job aids and the capacity to provide services. CHWs were dissatisfied with the lack of transportation, communication devices and financial incentives for carrying out their tasks. Factors influencing motivation and satisfaction did not differ across CHW socio-demographic characteristics. Nonetheless, older and less educated CHWs were more likely to be motivated by altruism, intrinsic needs and skill utilization, community respect and hope for employment. Less educated CHWs were more satisfied with service and quality factors and more wealthy CHWs satisfied with job aids. CONCLUSION AND RECOMMENDATIONS: A combination of financial and non-financial incentives is required to support motivation and satisfaction among CHWs. Although CHWs joined mainly due to their altruistic nature, they became discontented with the lack of monetary compensation, transportation and communication support received. With the planned rollout of the national CHW cadre, improved understanding of CHWs as a heterogeneous group with nuanced needs and varied ambitions is vital for ensuring sustainability.

Profile, knowledge, and work patterns of a cadre of maternal, newborn, and child health CHWs focusing on preventive and promotive services in Morogoro Region, Tanzania.

BACKGROUND: Despite impressive decreases in under-five mortality, progress in reducing maternal and neonatal mortality in Tanzania has been slow. We present an evaluation of a cadre of maternal, newborn, and child health community health worker (MNCH CHW) focused on preventive and promotive services during the antenatal and postpartum periods in Morogoro Region, Tanzania. Study findings review the effect of several critical design elements on knowledge, time allocation, service delivery, satisfaction, and motivation. METHODS: A quantitative survey on service delivery and knowledge was administered to 228 (of 238 trained) MNCH CHWs. Results are compared against surveys administered to (1) providers in nine health centers (n = 88) and (2) CHWs (n = 53) identified in the same districts prior to the program's start. Service delivery outputs were measured by register data and through a time motion study conducted among a sub-sample of 33 randomly selected MNCH CHWs. RESULTS: Ninety-seven percent of MNCH CHWs (n = 228) were interviewed: 55% male, 58% married, and 52% with secondary school education or higher. MNCH CHWs when compared to earlier CHWs were more likely to be unmarried, younger, and more educated. Mean MNCH CHW knowledge scores were <50% for 8 of 10 MNCH domains assessed and comparable to those observed for health center providers but lower than those for earlier CHWs. MNCH CHWs reported covering a mean of 186 households and were observed to provide MNCH services for 5 h weekly. Attendance of monthly facility-based supervision meetings was nearly universal and focused largely on registers, yet data quality assessments highlighted inconsistencies. Despite program plans to provide financial incentives and bicycles for transport, only 56% of CHWs had received financial incentives and none received bicycles. CONCLUSIONS: Initial rollout of MNCH CHWs yields important insights into addressing program challenges. The social profile of CHWs was not significantly associated with knowledge or service delivery, suggesting a broader range of community members could be recruited as CHWs. MNCH CHW time spent on service delivery was limited but comparable to the financial incentives received. Service delivery registers need to be simplified to reduce inconsistencies and yet expanded to include indicators on the timing of antenatal and postpartum visits.

Growth among HIV-infected children receiving antiretroviral therapy in Dar es Salaam, Tanzania.

We assembled a prospective cohort of 3144 human immunodeficiency virus (HIV) infected children aged <15 years initiating antiretroviral therapy (ART) in Dar es Salaam, Tanzania. The prospective relationships of baseline covariates with growth were examined using linear regression models. ART led to improvement in mean weight-for-age (WAZ), height/length-for-age (HAZ) and weight-for-length or body mass index (WLZ/BMIZ) scores. However, normal HAZ values were not attained over an average follow-up of 17.2 months. After 6 months of ART, underweight (P < 0.001), low CD4 count or percent (P < 0.001), stavudine containing regimens (P = 0.05) and advanced WHO disease stage (P < 0.001) at ART initiation were associated with better WAZ scores. Age >5 years on the other hand was associated with less increase in WAZ score after 6 months of ART (P < 0.001). These findings suggest that although ART improved the growth of the HIV-infected children in Tanzania, adjunct nutritional interventions may be needed to ensure that the growth of these children is optimized to the greatest extent possible.

First-line antiretroviral therapy and changes in lipid levels over 3 years among HIV-infected adults in Tanzania.

BACKGROUND: With the rapid rollout of antiretroviral therapy (ART) in sub-Saharan Africa (SSA), there has been an increasing concern about cardiovascular risks related to ART. However, data from human immunodeficiency virus (HIV)-infected populations from this region are very limited. METHODS: Among 6385 HIV-infected adults in Dar es Salaam, Tanzania, we investigated the nonfasting lipid changes over 3 years following ART initiation and their associations with different first-line ART agents that are commonly used in SSA. RESULTS: In the first 6 months of ART, the prevalence of dyslipidemia decreased from 69% to 54%, with triglyceride (TG) decreasing from 127 mg/dL to 113 mg/dL and high-density lipoprotein (HDL) cholesterol increasing from 39 mg/dL to 52 mg/dL. After 6 months, TG returned to its baseline level and increased to 139 mg/dL at 3 years; total cholesterol and low-density lipoprotein cholesterol continued to increase whereas HDL cholesterol leveled off. The prevalence of dyslipidemia increased to 73% after a 3-year follow-up. In multivariate analyses, patients on zidovudine-containing regimens had a greater reduction in TG levels at 6 months (-16.0 vs -6.3 mg/dL), and a lower increase at 3 years compared to patients on stavudine-containing regimens (2.1 vs 11.7 mg/dL, P < .001); patients on nevirapine-based regimens had a higher increase in HDL cholesterol levels at 3 years compared to those on efavirenz-based regimens (13.6 vs 9.5 mg/dL, P = .01). CONCLUSIONS: Our findings support the latest World Health Organization guidelines on the substitution of stavudine in first-line ART in resource-limited settings, and provide further evidence for selection of lipid-friendly ART for patients in SSA.

Household food security is inversely associated with undernutrition among adolescents from Kilosa, Tanzania.

Household food insecurity contributes to poor nutritional health, with negative consequences on growth and development during childhood. Although early childhood nutrition needs have received much attention, another important nutritional phase is adolescence. In a sample of 670 adolescents from Kilosa District, Tanzania, this study used 3 approaches to better understand the relationship between food insecurity and undernutrition. First, this study examined the associations between 3 commonly used measures of household food security and undernutrition among 670 adolescents from Kilosa District, Tanzania. The measures of household food security, energy adequacy per adult equivalent, dietary diversity score, and coping strategies index, were strongly correlated with each other and household assets (P < 0.05). Second, this study measured the nutritional status of adolescents in this district, finding a high prevalence of undernutrition (21% with BMI-for-age <5th percentile of the National Center for Health Statistics/WHO reference). Third, this study measured the association between the log odds of undernutrition (as the dependent variable) and each of the 3 measures of household food security. In separate models, household energy adequacy per adult equivalent and household dietary diversity score were inversely associated with undernutrition after adjusting for gender, age, puberty, and the interaction between age and puberty. By contrast, a greater use of coping strategies was not associated with undernutrition. Strategies focused on increasing household energy intake and improving dietary diversity among the most vulnerable households could improve the nutritional health of adolescents.

Nutritional status and mortality among HIV-infected patients receiving antiretroviral therapy in Tanzania.

BACKGROUND: Poor nutritional status is associated with immunologic impairment and adverse health outcomes among adults infected with human immunodeficiency virus (HIV). METHODS: We investigated body mass index (BMI), middle upper arm circumference (MUAC), and hemoglobin (Hgb) concentrations at initiation of antiretroviral therapy (ART) in 18,271 HIV-infected Tanzanian adults and their changes in the first 3 months of ART, in relation to the subsequent risk of death. RESULTS: Lower BMI, MUAC, and Hgb concentrations at ART initiation were strongly associated with a higher risk of death within 3 months. Among patients who survived >3 months after ART initiation, those with a decrease in weight, MUAC, or Hgb concentrations by 3 months had a higher risk of death during the first year. After 1 year, only a decrease in MUAC by 3 months after ART initiation was associated with a higher risk of death. Weight loss was associated with a higher risk of death across all levels of baseline BMI, with the highest risk observed among patients with BMI <17 kg/m(2) (relative risk, 7.9; 95% confidence interval, 4.4-14.4). CONCLUSIONS: Poor nutritional status at ART initiation and decreased nutritional status in the first 3 months of ART were strong independent predictors of mortality. The role of nutritional interventions as adjunct therapies to ART merits further investigation.

Quality of Sick Child-Care Delivered by Community Health Workers in Tanzania.

BACKGROUND: Community health worker (CHW) interventions to manage childhood illness is a strategy promoted by the global health community which involves training and supporting CHW to assess, classify and treat sick children at home, using an algorithm adapted from the Integrated Management of Childhood Illness (IMCI). To inform CHW policy, the Government of Tanzania launched a program in 2011 to determine if community case management (CCM) of malaria, pneumonia and diarrhea could be implemented by CHW in that country. METHODS: This paper reports the results of an observational study on the CCM service delivery quality of a trial cohort of CHW in Tanzania, called WAJA. In 2014, teams of data collectors, employees of the Ministry of Health and Social Welfare trained in IMCI, assessed the IMCI skills rendered by a sample of WAJA on sick children who presented to WAJA with illness signs and symptoms in their communities. The assessment included direct observations of WAJA IMCI episodes and expert re-assessment of the same children seen by WAJA to assess the congruence between the assessment, classification and treatment outcomes of WAJA cases and those from cases conducted by expert re-assessors. RESULTS: In the majority of cases, WAJA correctly assess sick children for CCM-treatable illnesses (malaria, pneumonia, and diarrhea) and general danger signs (90% and 89%, respectively), but too few correctly assess for physical danger signs (39%); on classification in the majority of cases (73%) WAJA correctly classified illness, though more for CCM-treatable illnesses (83%). In majority of cases (78%) WAJA treated children correctly (84% of malaria, 74% pneumonia, and 71% diarrhea cases). Errors were often associated with lapses in health systems support, mainly supervision and logistics. CONCLUSION: CCM is a feasible strategy for CHW in Tanzania, who, in the majority of cases, implemented the approach as well as IMCI expert re-assessors. Nevertheless, for CCM to be effective, in Tanzania, a strategy to implement it must be coordinated with efforts to strengthen local health systems.

An exploration of the feasibility, acceptability, and effectiveness of professional, multitasked community health workers in Tanzania.

Despite four decades of global experience with community-based primary health care, the strategic details of community health worker (CHW) recruitment, training, compensation, and deployment remain the subject of continuing discussion and debate. Responsibilities and levels of clinical expertise also vary greatly, as well as contrasting roles of public- versus private-sector organisations as organisers of CHW effort. This paper describes a programme of implementation research in Tanzania, known as the Connect Project, which aims to guide national policies with evidence on the impact and process of deploying of paid, professional CHWs. Connect is a randomised-controlled trial of community exposure to CHW integrated primary health-care services. A qualitative appraisal of reactions to CHW implementation of community stakeholders, frontline workers, supervisors, and local managers is reviewed. Results highlight the imperative to plan and implement CHW programmes as a component of a broader, integrated effort to strengthen the health system. Specifically, the introduction of a CHW programme in Tanzania should draw upon community structures and institutions and strengthen mechanisms to sustain their participation in primary health care. This should be coordinated with efforts to address poorly functioning logistics and supervisory systems and human resource and management challenges.

Prevalence and Risk Factors for Overweight and Obesity among HIV-Infected Adults in Dar es Salaam, Tanzania.

BACKGROUND: Overweight and obesity are increasingly prevalent among HIV-infected populations. We describe their prevalence and associated risk factors among HIV-infected adults in Dar es Salaam, Tanzania. METHODS: A cross-sectional study was conducted to determine the proportion of patients who were overweight or obese at enrollment to care and treatment centres from 2004 to 2011. Multivariate relative risk regression models were fit to identify risk factors. RESULTS: A total of 53 825 patients were included in the analysis. In all, 16% of women and 8% of men were overweight, while 7% and 2% were obese, respectively. In multivariate analyses, older age, higher CD4 count, higher hemoglobin levels, female sex, and being married were associated with obesity and overweight. World Health Organization HIV disease stage, tuberculosis history, and previous antiretroviral therapy were inversely associated with obesity and overweight. CONCLUSION: Overweight and obesity were highly prevalent among HIV-infected patients. Screening for overweight and obesity and focused interventions should be integrated into HIV care.

Nutritional Status and Other Baseline Predictors of Mortality among HIV-Infected Children Initiating Antiretroviral Therapy in Tanzania.

BACKGROUND: We assembled a prospective cohort of 3144 children less than 15 years of age initiating antiretroviral therapy (ART) in Dar es Salaam, Tanzania. METHODS: The relationships of nutritional status and other baseline characteristics in relation to mortality were examined using Cox proportional hazards model. RESULTS: Compared with children with weight for age (WAZ) > -1, those with WAZ ≤ -2 to < -3 had a nearly double risk of death (relative risk [RR], 1.85; 95% confidence interval [CI], 1.10-3.11), and among those with WAZ ≤ -3, the risk more than tripled (RR, 3.36; 95% CI, 2.12-5.32). Other baseline risk factors for overall mortality included severe anemia (P < .001), severe immune suppression (P = .02), history of tuberculosis (P = .01), opportunistic infections (P < .001), living in the poorest district (P < .001), and advanced World Health Organization stage (P = .003). CONCLUSIONS: To sustain the obtained benefit of ART in this setting, interventions to improve nutritional status may be used as an adjunct to ART.
