    Review of policy action for healthy environmentally sustainable food systems in sub-Saharan Africa
    (Current Opinion in Environmental Sustainability, 2023) Holdsworth, M.; Kimenju, S.; Hallen, G.; Laar, A.; Oti, S.O.
    Many sub-Saharan African (SSA) countries are experiencing multiple burdens of malnutrition. Rising overweight/obesity coexist alongside persistent burdens of under-nutrition and multiple micronutrient deficiencies. Poverty and social inequity remain key drivers of unhealthy diets and malnutrition. Diets in SSA are increasingly transitioning towards unhealthy (energy dense, nutrient-poor and unsafe) and environmentally unsustainable diets. Healthy, sustainable food systems are required to deal with these considerable challenges equitably, so policy action needs to balance the health, environmental and economic dimensions of diets and food systems. We review evidence in recent literature for which policy actions have the best chance of success in SSA by appraising their likely impact, relevance, cost/affordability and feasibility to help guide policymakers and researchers in their development and evaluation.

    The influence of depressive symptoms and school-going status on risky behaviors: a pooled analysis among adolescents in six sub-Saharan African countries
    (Frontiers in Psychiatry, 2023) Partap, U.; Assefa, N.; Adanu, R.; et al.
    Background: Evidence from sub-Saharan Africa (SSA) regarding risky behaviors among adolescents remains scarce, despite the large population (approximately 249 million out of 1.2 billion globally in 2019) of adolescents in the region. We aimed to examine the potential influence of depressive symptoms and school going status on risky behaviors among adolescents in six SSA countries. Methods: We used individual cross-sectional data from adolescents aged 10–19 based in eight communities across six SSA countries, participating in the ARISE Network Adolescent Health Study (N = 7,661). Outcomes of interest were cigarette or tobacco use, alcohol use, other substance use, getting into a physical fight, no condom use during last sexual intercourse, and suicidal behavior. We examined the proportion of adolescents reporting these behaviors, and examined potential effects of depressive symptoms [tertiles of 6-item Kutcher Adolescent Depression Scale (KADS-6) score] and school-going status on these behaviors using mixed effects Poisson regression models. We also assessed effect modification of associations by sex, age, and school-going status. Results: The proportion of adolescents reporting risky behaviors was varied, from 2.2% for suicidal behaviors to 26.2% for getting into a physical fight. Being in the higher tertiles of KADS-6 score was associated with increased risk of almost all risky behaviors [adjusted risk ratio (RR) for highest KADS-6 tertile for alcohol use: 1.70, 95% confidence interval (95% CI): 1.48–1.95, p < 0.001; for physical fight: 1.52, 95% CI: 1.36–1.70, p < 0.001; for suicidal behavior: 7.07, 95% CI: 2.69–18.57, p < 0.001]. Being in school was associated with reduced risk of substance use (RR for alcohol use: 0.73, 95% CI: 0.53–1.00, p = 0.047), and not using a condom (RR: 0.81, 95% CI: 0.66–0.99, p = 0.040). There was evidence of modification of the effect of school-going status on risky behaviors by age and sex. Conclusion: Our findings reinforce the need for a greater focus on risky behaviors among adolescents in SSA. Addressing depressive symptoms among adolescents, facilitating school attendance and using schools as platforms to improve health may help reduce risky behaviors in this population. Further research is also required to better assess the potential bidirectionality of associations.

    Retention and risk factors for attrition among adults in antiretroviral treatment programmes in Tanzania, Uganda and Zambia
    (Tropical Medicine and International Health, 2014) Koole, O.; Tsui, S.; Torpey, K; et al.
    objectives We assessed retention and predictors of attrition (recorded death or loss to follow-up) in antiretroviral treatment (ART) clinics in Tanzania, Uganda and Zambia. methods We conducted a retrospective cohort study among adults (≥18 years) starting ART during 2003–2010. We purposefully selected six health facilities per country and randomly selected 250 patients from each facility. Patients who visited clinics at least once during the 90 days before data abstraction were defined as retained. Data on individual and programme level risk factors for attrition were obtained through chart review and clinic manager interviews. Kaplan–Meier curves for retention across sites were created. Predictors of attrition were assessed using a multivariable Cox proportional hazards model, adjusted for site-level clustering. results From 17 facilities, 4147 patients were included. Retention ranged from 52.0% to 96.2% at 1 year to 25.8%–90.4% at 4 years. Multivariable analysis of ART initiation characteristics found the following independent risk factors for attrition: younger age [adjusted hazard ratio (aHR) and 95% confidence interval (95%CI) = 1.30 (1.14–1.47)], WHO stage 4 ([aHR (95% CI): 1.56 (1.29–1.88)], >10% bodyweight loss [aHR (95%CI) = 1.17 (1.00–1.38)], poor functional status [ambulatory aHR (95%CI) = 1.29 (1.09–1.54); bedridden aHR1.54 (1.15–2.07)], and increasing years of clinic operation prior to ART initiation in government facilities [aHR (95%CI) = 1.17 (1.10–1.23)]. Patients with higher CD4 cell count were less likely to experience attrition [aHR (95%CI) = 0.88 (0.78–1.00)] for every log (tenfold) increase. Sites offering community ART dispensing [aHR (95% CI) = 0.55 (0.30–1.01) for women; 0.40 (0.21–0.75) for men] had significantly less attrition. conclusions Patient retention to an individual programme worsened over time especially among males, younger persons and those with poor clinical indicators. Community ART drug dispensing programmes could improve retention.

    Role and outcomes of community health workers in HIV care in sub-Saharan Africa: a systematic review
    (Journal of the International AIDS Society, 2013) Mwai, G.W.; Mburu, G.; Torpey, K.; et al.
    Introduction: The provision of HIV treatment and care in sub-Saharan Africa faces multiple challenges, including weak health systems and attrition of trained health workers. One potential response to overcome these challenges has been to engage community health workers (CHWs). Methodology: A systematic literature search for quantitative and qualitative studies describing the role and outcomes of CHWs in HIV care between inception and December 2012 in sub-Saharan Africa was performed in the following databases: PubMed, PsychINFO, Embase, Web of Science, JSTOR, WHOLIS, Google Scholar and SAGE journals online. Bibliographies of included articles were also searched. A narrative synthesis approach was used to analyze common emerging themes on the role and outcomes of CHWs in HIV care in sub-Saharan Africa. Results: In total, 21 studies met the inclusion criteria, documenting a range of tasks performed by CHWs. These included patient support (counselling, home-based care, education, adherence support and livelihood support) and health service support (screening, referral and health service organization and surveillance). CHWs were reported to enhance the reach, uptake and quality of HIV services, as well as the dignity, quality of life and retention in care of people living with HIV. The presence of CHWs in clinics was reported to reduce waiting times, streamline patient flow and reduce the workload of health workers. Clinical outcomes appeared not to be compromised, with no differences in virologic failure and mortality comparing patients under community-based and those under facility-based care. Despite these benefits, CHWs faced challenges related to lack of recognition, remuneration and involvement in decision making. Conclusions: CHWs can clearly contribute to HIV services delivery and strengthen human resource capacity in sub-Saharan Africa. For their contribution to be sustained, CHWs need to be recognized, remunerated and integrated in wider health systems. Further research focusing on comparative costs of CHW interventions and successful models for mainstreaming CHWs into wider health systems is needed.

    Factors associated with depressive symptoms and suicidal ideation and behaviours amongst sub-Saharan African adolescents aged 10-19 years: cross-sectional study.
    (Tropical Medicine and International Health, 2020-01-25) Manu, A.; Nyundo, A.; Regan, M.; Ismail, A.; Chukwu, A.; Dessie, Y.; Njau, T.; Kaaya, S.F.; Smith, F.M.C.
    OBJECTIVE: This study aimed to determine the burden of depression, suicidal ideation and suicidal behaviour amongst adolescents at sites in six sub-Saharan African countries and examine associated risk and protective factors. METHODS: Household-based cross-sectional study involving male and female adolescents ages 10-19 years. A total of 7,662 adolescents from eight sites in six countries participated in the survey. Three sites were urban: Dar es Salaam (Tanzania), Harar (Ethiopia) and Ibadan (Nigeria); five were rural: Dodoma (Tanzania), Iganga/Mayuge (Uganda), Kersa (Ethiopia), Ningo Prampram (Ghana) and Nouna (Burkina Faso). Log-binomials models were used to estimate relative risks and confidence intervals for factors associated with depression and suicidal behaviour. This was supplemented using log-Poisson models as needed. RESULTS: The prevalence of suicidal behaviour over the last 12 months ranged between 1.2% and 12.4% in the eight sites. Depressive symptoms and suicidal ideation/behaviours were associated with older age, female sex, food insecurity, poor access to health care and substance use. Depression was strongly associated with increased risk of suicidal behaviour at two sites where the multivariate model converged: Harar, Ethiopia (RR = 3.5, 95% CI 1.8, 7.0, P < 0.05) and Ibadan, Nigeria (RR = 3.7, 95% CI 2.2, 6.3, P < 0.0001). CONCLUSIONS: Depressive symptoms and suicidal behaviour are common amongst sub-Saharan African adolescents at these 8 sites. Most factors associated with depressive symptoms are modifiable and preventable. Routine screening for depressive symptoms in services frequented by adolescents in these and similar communities would be crucial in early detection and prompt intervention.

    Sexual and reproductive health knowledge among adolescents in eight sites across sub-Saharan Africa
    (Tropical Medicine & International Health, 2019-11-05) Adanu, R.; Finlay, J.E.; Assefa, N.; Mwanyika-Sando, M.; Dessie, Y.; Harling, G.; Njau, T.; Chukwu, A.; Oduola, A.; Shah, I.; Bukenya, J.
    objective To examine knowledge of menstruation, HIV and STIs other than HIV across eight sites in SSA to develop effective programmatic interventions enabling adolescents to achieve positive SRH as their transition to adulthood. methods We combine data from eight Health and Demographic Surveillance Sites across sub-Saharan Africa, from an adolescent-specific survey that included 7116 males and females age 10–19 years old. We provide pooled and site-specific estimates from multiple analytic models examining the how year-specific age, school attendance and work correlate with knowledge of menstruation, HIV knowledge and knowledge of sexually transmitted infections (STIs) other than HIV. results Many adolescents lack knowledge of menstruation (37.3%, 95% CI 31.8, 43.1 do not know of menstruation) and STIs other than HIV (55.9%, 95% CI 50.4, 61.3 do not know of other STIs). In multivariate analysis, older age, being in school and wealth are significant positive correlates of STI knowledge. Older adolescent age, female sex and being in school are significant positive correlates of knowledge of menstruation. Knowledge of HIV is high (89.7%, 95% CI 8.3, 12.7 know of HIV) and relatively similar across adolescent age, sex, wealth and school and work attendance. conclusion Knowledge of HIV is widespread across adolescents in these communities in sub- Saharan Africa, but knowledge of other dimensions of sexual and reproductive health – menstruation and other STIs in this study – is lacking especially for early adolescents (10- to 14-year olds). The dissemination of more comprehensive sexual and reproductive health information is needed within these and similar communities in SSA to help adolescents gain insight on how to make their own decisions towards positive adolescent sexual and reproductive health and protect them from risks.

    Stocking and over-the-counter sale of misoprostol for medical abortion in Ghana’s community pharmacies: comparison of questionnaire and mystery client survey
    (International Journal of Pharmacy Practice, 2019-11-20) Ganle, J.K.; Busia, N.T.; Baatiema, L.
    Objectives In many sub-Saharan African countries with restricted safe abortion services, community pharmacies are important sources of abortifacients. However, data on stocking and over-the-counter sale of abortifacients in community pharmacies are often limited. The main objective of this study was to compare stocking and over-the-counter sale of misoprostol at community pharmacies using questionnaire and mystery client surveys in Ghana. Methods A cross-sectional questionnaire-based survey, complemented with a mystery client survey, was conducted at 165 randomly selected community pharmacies in Accra, Ghana. Structured questionnaires were administered to pharmacists/pharmacy workers. A mystery client survey to each of these pharmacies was also undertaken. Descriptive statistical techniques (frequencies and proportions) were used to estimate and compare stocking and over-the-counter sale of misoprostol at community pharmacies from the two data collection methods. Key findings Some 50.3% (83) of community pharmacists/pharmacy workers reported stocking misoprostol and selling it over-the-counter for medical abortion in the questionnaire-based survey. However, in the mystery client survey, 122 (74%) pharmacists/pharmacy workers reported stocking misoprostol and actually selling it over-the-counter to the mystery clients. Thus approximately 39 (24%) more pharmacies stocked misoprostol and sold it over-the-counter even though they originally denied stocking the drug in the questionnaire survey. Also, the drug was often sold without a prescription, and many did so without asking for a confirmatory pregnancy test or gestational age. Conclusions In contexts where access to safe abortion services is restricted, mystery client surveys, rather than conventional questionnaire-based survey techniques, may better illuminate stocking and over-the-counter sale of abortifacients at community pharmacies.

    Impact of an electronic clinical decision support system on workflow in antenatal care: The QUALMAT eCDSS in rural health care facilities in Ghana and Tanzania
    (Global Health Action, 2015-01) Mensah, N.; Sukums, F.; Awine, T.; Meid, A.; Williams, J.; Akweongo, P.; Kaltschmidt, J.; Haefeli, W.E.; Blank, A.
    BACKGROUND: The implementation of new technology can interrupt established workflows in health care settings. The Quality of Maternal Care (QUALMAT) project has introduced an electronic clinical decision support system (eCDSS) for antenatal care (ANC) and delivery in rural primary health care facilities in Africa. OBJECTIVE: This study was carried out to investigate the influence of the QUALMAT eCDSS on the workflow of health care workers in rural primary health care facilities in Ghana and Tanzania. DESIGN: A direct observation, time-and-motion study on ANC processes was conducted using a structured data sheet with predefined major task categories. The duration and sequence of tasks performed during ANC visits were observed, and changes after the implementation of the eCDSS were analyzed. RESULTS: In 24 QUALMAT study sites, 214 observations of ANC visits (144 in Ghana, 70 in Tanzania) were carried out at baseline and 148 observations (104 in Ghana, 44 in Tanzania) after the software was implemented in 12 of those sites. The median time spent combined for all centers in both countries to provide ANC at baseline was 6.5 min [interquartile range (IQR) =4.0-10.6]. Although the time spent on ANC increased in Tanzania and Ghana after the eCDSS implementation as compared to baseline, overall there was no significant increase in time used for ANC activities (0.51 min, p=0.06 in Ghana; and 0.54 min, p=0.26 in Tanzania) as compared to the control sites without the eCDSS. The percentage of medical history taking in women who had subsequent examinations increased after eCDSS implementation from 58.2% (39/67) to 95.3% (61/64) p<0.001 in Ghana but not in Tanzania [from 65.4% (17/26) to 71.4% (15/21) p=0.70]. CONCLUSIONS: The QUALMAT eCDSS does not increase the time needed for ANC but partly streamlined workflow at sites in Ghana, showing the potential of such a system to influence quality of care positively.
