Implementing and Evaluating Community Health Worker-Led Cardiovascular Disease Risk Screening Intervention in Sub-Saharan Africa Communities: A Participatory Implementation Research Protocol.

The increasing burden of non-communicable diseases (NCDs), particularly cardiovascular diseases (CVD) in low- and middle-income countries (LMICs) poses a considerable threat to public health. Community-driven CVD risk screening, referral and follow-up of those at high CVDs risk is essential to supporting early identification, treatment and secondary prevention of cardiovascular events such as stroke and myocardial infarction. This protocol describes a multi-country study that aims to implement and evaluate a community health worker (CHW)-led CVD risk screening programme to enhance referral linkages within the local primary care systems in sub-Saharan Africa (SSA), using a participatory implementation science approach. The study builds upon a prior community-driven multicentre study conducted by the Collaboration for Evidence-based Health Care and Public Health in Africa (CEBHA+). This is a participatory implementation research. The study will leverage on the CVD risk citizen science pilot studies conducted in the four selected CEBHA+ project countries (viz. Ethiopia, Rwanda, Malawi, and South Africa). Through planned engagements with communities and health system stakeholders, CHWs and lay health worker volunteers will be recruited and trained to screen and identify persons that are at high risk of CVD, provide referral services, and follow-up at designated community health clinics. In each country, we will use a multi-stage random sampling to select and then screen 1000 study participants aged 35-70 years from two communities (one rural and one urban). Screening will be done using a simple validated non-laboratory-based CVD risk assessment mobile application. The RE-AIM model will be used in evaluating the project implementation outcomes, including reach, fidelity, adoption and perceived effectiveness. Developing the capacities of CHWs and lay health worker volunteers in SSA to support population-based, non-invasive population-based CVD risk prevention has the potential to impact on early identification, treatment and secondary prevention of CVDs in often under-resourced communities. Using a participatory research approach to implementing mobile phone-based CHW-led CVD risk screening, referral and follow-up in SSA will provide the evidence needed to determine the effectiveness of CVD risk screening and the potential for scaling up in the wider region

Children with Moderate Acute Malnutrition with No Access to Supplementary Feeding Programmes Experience High Rates of Deterioration and No Improvement: Results from a Prospective Cohort Study in Rural Ethiopia

Background: Children with moderate acute malnutrition (MAM) have an increased risk of mortality, infections and impaired physical and cognitive development compared to well-nourished children. In parts of Ethiopia not considered chronically food insecure there are no supplementary feeding programmes (SFPs) for treating MAM. The short-term outcomes of children who have MAM in such areas are not currently described, and there remains an urgent need for evidence-based policy recommendations. Methods: We defined MAM as mid-upper arm circumference (MUAC) of ≥11.0cm and <12.5cm with no bilateral pitting oedema to include Ethiopian government and World Health Organisation cut-offs. We prospectively surveyed 884 children aged 6–59 months living with MAM in a rural area of Ethiopia not eligible for a supplementary feeding programme. Weekly home visits were made for seven months (28 weeks), covering the end of peak malnutrition through to the post-harvest period (the most food secure window), collecting anthropometric, socio-demographic and food security data. Results: By the end of the study follow up, 32.5% (287/884) remained with MAM, 9.3% (82/884) experienced at least one episode of SAM (MUAC <11cm and/or bilateral pitting oedema), and 0.9% (8/884) died. Only 54.2% of the children recovered with no episode of SAM by the end of the study. Of those who developed SAM half still had MAM at the end of the follow up period. The median (interquartile range) time to recovery was 9 (4–15) weeks. Children with the lowest MUAC at enrolment had a significantly higher risk of remaining with MAM and a lower chance of recovering. Conclusions: Children with MAM during the post-harvest season in an area not eligible for SFP experience an extremely high incidence of SAM and a low recovery rate. Not having a targeted nutrition-specific intervention to address MAM in this context places children with MAM at excessive risk of adverse outcomes. Further preventive and curative approaches should urgently be considered

Women’s empowerment and child growth faltering in Ethiopia: evidence from the Demographic and Health Survey

Background: Despite numerous national and international efforts to alleviate child growth faltering, it remains a global health challenge. There is a growing body of literature that recognizes the importance of women’s empowerment in a wide range of public health topics, such as the utilization of maternal healthcare services, agricultural productivity, and child nutrition. However, in Ethiopia, the relationship between women’s empowerment and child nutritional status is not studied at the national level. This study aimed to determine the association between women’s empowerment and growth faltering in under-5 children in Ethiopia. Methods: The data source for this analysis is the 2016 Ethiopian Demographic and Health Survey (EDHS): a nationally representative household survey on healthcare. The EDHS employed a two-stage stratified cluster sampling technique. We computed standard women’s empowerment indices, following the Survey-based Women’s emPowERment index approach. A multilevel logistic regression model that accounted for cluster-level random effects was used to estimate the association between women’s empowerment and child growth faltering (stunting, wasting and underweight). Results: Attitude to violence, social independence, and decision-making were the three domains of women’s empowerment that were associated with child growth faltering. One standard deviation increase in each domain of empowerment was associated with a reduction in the odds of stunting: attitude towards violence (AOR = 0.92; 95% CI 0.88–0.96; p < 0.001), social independence (AOR = 0.95; 95% CI 0.89–0.99; p = 0.049), and decision-making (AOR = 0.93; 95% CI 0.87–0.99; p = 0.023). Similarly, each standard deviation increase in attitude towards violence (AOR = 0.93; 95% CI 0.89–0.98; p = 0.008), social independence (AOR = 0.91; 95% CI 0.86–0.97; p = 0.002), and decision-making (AOR = 0.92; 95% CI 0.86–0.99; p = 0.020) were associated with a decrease in the odds of having underweight child. Conclusions: Ensuring women’s empowerment both in the household and in the community could have the potential to decrease stunting and underweight in a rapidly developing country like Ethiopia. Policymakers and health professionals need to consider women’s empowerment in this unique context to improve nutritional outcomes for children and alleviate growth faltering.</p
