Preventing relapse from wasting: the role of sociodemographic, child feeding, and health care determinants and of wasting prevention interventions in Burkina Faso and Mali

Background Relapse among children treated for wasting is a major concern. We estimated the frequency and determinants of relapse to wasting in two populations exposed to PROMIS, an integrated wasting prevention and screening program. Methods Using longitudinal data from PROMIS trials in Burkina Faso and Mali, we calculated the incidence rate and period prevalence of relapse to wasting within 6 months in children who had ≥1 wasting episode ending when they were ≥6 months old for which they were treated and recovered (NBurkina Faso=247; NMali=220). We used backward elimination to select a multivariable model of sociodemographic, nutrition- and health-related determinants of relapse. We also evaluated if prevention interventions (behavior change communication (BCC) and/or small quantity lipid-based nutrient supplements (SQ-LNS) were associated with relapse, adjusting for confounders and trial arm. Results Relapse incidence was 2.6 per child-year in Burkina Faso (N=291 episodes) and 1.6 per child-year in Mali (N=300 episodes). In both countries, being fed the recommended food frequency or iron-rich foods after recovering from wasting was associated with lower risk of relapse. In Mali, longer wasting episodes, lack of minimally diverse diet consumption, and several caregiver/household characteristics were associated with lower risk of relapse. In both countries, receipt of BCC after recovery from wasting was associated with lower risk of relapse (Incidence rate ratio [IRR]Burkina Faso = 0.51 [95% confidence interval [CI] = 0.30, 0.86]; IRRMali = 0.26 [95% CI = 0.11, 0.65]), as was receipt of SQ-LNS (IRRBurkina Faso = 0.33 [95% CI = 0.16, 0.70]; (IRRMali = 0.43 [95% CI = 0.19, 0.94]), after adjustments. Conclusion Children being discharged from wasting treatment are a well-defined vulnerable population who stand to benefit from targeted post-discharge preventive interventions. BCC that includes advice on optimal infant and young child feeding practices and SQ-LNS may help prevent wasting relapse in at-risk children.

Assessing equity in effects of nutritional supplementation for child growth, development, and anemia

Undernutrition in early childhood causes stunted growth, cognitive delays, and anemia, with effects often magnified among children from the poorest households. Small-quantity lipid-based nutrient supplements (SQ-LNS) are effective in addressing undernutrition and improving child development. As momentum builds to scale up SQ-LNS for children aged 6-24 months in the Global South, a key concern is achieving equity in its distribution and outcomes. We performed equity analysis of individual participant data from 14 randomized controlled trials in nine countries (N=37,707 children) to assess SQ-LNS effects on child growth, development, and anemia across levels of an international wealth index. Benefits of SQ-LNS were consistent across the wealth spectrum, leading to similar improvements in child growth, development, and anemia regardless of wealth. However, such equal benefits of SQ-LNS did not erase large inequities in child growth and development between the poorest and wealthier households.

Community volunteers deliver integrated prevention and treatment services to reduce child wasting in Chad

Community volunteers deliver integrated prevention and treatment services to reduce child wasting in Chad

Wasting is a persistent public health problem affecting 45 million children under five years of age worldwide. Wasting is responsible for the deaths of 875,000 children under the age of five every year. Children who survive often suffer from long-term cognitive and physical disabilities UNICEF, the World Health Organization, and the World Bank 2021; Black et al. 2013). Member countries of the World Health Assembly (WHA) have agreed to reduce and maintain the prevalence of wasting to less than 5 percent by 2025. Most Sahelian countries are off track to meet the WHA targets and in Chad, the prevalence of wasting is still unacceptably high at 14 percent and shows large regional disparities (UNICEF, the World Health Organization, and the World Bank 2020). While both wasting prevention and treatment programs hold the potential to reduce child wasting, substantial synergies can be expected when prevention is integrated with screening, referral, and treatment services. Such integration should happen at the community level to maximize the accessibility of services for caregivers and their children.
