Leveraging the Scaling Up Nutrition Movement to Operationalize Stunting Prevention Activities: Implementation Lessons From Rural Malawi.

BACKGROUND: The rural district of Ntchisi is in the central region of Malawi. Among children aged 6 to 23 months, the stunting prevalence is 40% to 50%. To address this high prevalence, the World Food Programme, with cooperating partners, supported the Government of Malawi to implement an integrated stunting prevention program entitled The Right Foods at the Right Time from 2013 to 2018. OBJECTIVE: To provide implementation lessons learned from systematic documentation of how the Scaling Up Nutrition (SUN) movement, combined with other international and national initiatives and policies, was translated into tailored programming. METHODS: During program conception, early design, and implementation, this descriptive study systematically documented the process of translating SUN principles and government policies into an operational stunting prevention program in rural Malawi. RESULTS: We identified 8 factors that contributed to successful translation of policy into program activities: (1) well-structured National SUN framework, (2) reliable coordination platforms and district ownership, (3) systematic and evidence-informed program design, (4) multiple forms of data used to inform program planning, (5) multisectoral implementation approaches to stunting prevention, (6) innovation in technology to improve overall program efficiency, (7) systematic collaboration among diverse stakeholders, and (8) strong public health nutrition capacity of program team members. CONCLUSIONS: Lessons from this nutrition program in Ntchisi, Malawi, provide one case illustrating how the SUN movement, government policies, and global evidence base can be operationalized into tailored programming for improving nutrition.

Process Evaluation of a Large-Scale Community-Based Nutrition Program in Malawi.

BACKGROUND: Global attention to the study of nutrition program implementation has been inadequate yet is critical for effective delivery and impact at scale. OBJECTIVES: The objective of this mixed-methods process evaluation study was to measure the recruitment, fidelity, and reach of a large-scale, community-based nutrition program in Malawi. METHODS: The nutrition program delivered a small-quantity lipid-based nutrient supplement (SQ-LNS) and social and behavior change communication (SBCC) to improve infant and young child feeding (IYCF) and water, sanitation, and hygiene (WASH) practices in households with children aged 6-23 mo. Program monitoring and evaluation data were used to measure program recruitment, reach, and fidelity. Structured direct observations and knowledge questionnaires with program volunteers measured quality aspects of program fidelity. The number of times activities were done correctly was used to tabulate proportions used to represent program functioning. RESULTS: Half (49.5%) of eligible children redeemed program benefits by 8 mo of age during the first 4 y of program implementation. Implementation of training activities for SBCC cadres exceeded program targets (100.6%), but the completion of certain modules (breastfeeding and complementary feeding) was lower (22.9% and 18.6%, respectively). Knowledge of IYCF, WASH, and SQ-LNS messages by volunteers was >85% for most messages, except ability to list the 6 food groups (35.7%). Structured direct observations of SQ-LNS distributions indicated high fidelity to program design, whereas those of household-level counseling sessions revealed lack of age-appropriate messaging. Program reach showed participation in monthly distribution sessions of 81.0%, group counseling of 93.3%, and individual-level counseling of 36.9%. CONCLUSIONS: This community-based nutrition program was implemented with high fidelity and quality, with specific interventions requiring further attention. The documentation of implementation contributes to our understanding about how program impacts were achieved.

Systematic review of the treatment of moderate acute malnutrition using food products.

There is currently a lack of international guidance on the most appropriate treatment for moderate acute malnutrition (MAM), and discrepancies in national treatment guidelines exist. We aimed to explore whether food interventions are effective for MAM children 6-59 months old and whether they result in better outcomes compared with no treatment or management with nutrition counselling. A systematic literature search was conducted in October 2018, identifying studies that compared treating MAM children with food products versus management with counselling or no intervention. A total of 673 abstracts were screened, 101 full texts were read, and one study was identified that met our inclusion criteria. After broadening the criteria to include micronutrients in the control group and enrolment based on out-dated anthropometric criteria, 11 studies were identified for inclusion. Seven of these found food products to be superior for anthropometric outcomes compared with counselling and/or micronutrient supplementation; two of the studies found no significant benefit of a food product intervention; and two studies were inconclusive. Hence, the majority of studies in this review found that food products resulted in greater anthropometric gains than counselling or micronutrient interventions. This was especially true if the supplementary food provided was of suitable quality and provided for an adequate duration. Improving quality of and adherence to counselling may improve its effectiveness, particularly in food secure contexts. There is currently a paucity of comparable studies on this topic as well as a lack of studies that include important functional outcomes beyond anthropometric proxies.

Strengths and limitations of computer assisted telephone interviews (CATI) for nutrition data collection in rural Kenya.

Despite progress in fighting undernutrition, Africa has the highest rates of undernutrition globally, exacerbated by drought and conflict. Mobile phones are emerging as a tool for rapid, cost effective data collection at scale in Africa, as mobile phone subscriptions and phone ownership increase at the highest rates globally. To assess the feasibility and biases of collecting nutrition data via computer assisted telephone interviews (CATI) to mobile phones, we measured Minimum Dietary Diversity for Women (MDD-W) and Minimum Acceptable Diet for Infants and Young Children (MAD) using a one-week test-retest study on 1,821 households in Kenya. Accuracy and bias were assessed by comparing individual scores and population prevalence of undernutrition collected via CATI with data collected via traditional face-to-face (F2F) surveys. We were able to reach 75% (n = 1366) of study participants via CATI. Women's reported nutrition scores did not change with mode for MDD-W, but children's nutrition scores were significantly higher when measured via CATI for both the dietary diversity (mean increase of 0.45 food groups, 95% confidence interval 0.34-0.56) and meal frequency (mean increase of 0.75 meals per day, 95% confidence interval 0.53-0.96) components of MAD. This resulted in a 17% higher inferred prevalence of adequate diets for infants and young children via CATI. Women without mobile-phone access were younger and had fewer assets than women with access, but only marginally lower dietary diversity, resulting in a small non-coverage bias of 1-7% due to exclusion of participants without mobile phones. Thus, collecting nutrition data from rural women in Africa with mobile phones may result in 0% (no change) to as much as 25% higher nutrition estimates than collecting that information in face-to-face interviews.

Monitoring and evaluation design of Malawi's Right Foods at the Right Time nutrition program.

Child stunting is a public health problem in Malawi. In 2014, the Government of Malawi launched the Right Foods at the Right Time (RFRT) program in Ntchisi district delivering nutrition social and behavior change communication, a small-quantity lipid-based nutrient supplement to children 6-23 months, and nutrition sensitive activities. Monitoring and evaluation (M&E) systems are key aspects of successful program implementation. We describe these and the methodology for an impact evaluation that was conducted for this program. Two monitoring systems using traditional and electronic platforms were established to register and track program delivery and processes including number of eligible beneficiaries, worker performance, program participation, and to monitor input, output, and outcome indicators. The impact evaluation used comparative cross-sectional and longitudinal designs to assess impact on anthropometric and infant and young child feeding outcomes. Three cross-sectional surveys (base-, mid-, and end-line) and two longitudinal cohorts of children followed in 6-month intervals from 6 to 24 months of age, were conducted in sampled households in the program and a neighboring comparison district. Additional M&E included qualitative studies, a process evaluation, and a cost-effectiveness study. The current paper describes lessons from this program's M&E, and demonstrates how multiple implementation research activities can inform course-correction and program scale-up.
