The impact of a continuum of care intervention from prevention to treatment on child wasting compared to usual community group activities: A cluster randomized controlled trial in Mali

Background Child wasting is associated with a high mortality risk and remains a persistent public health challenge. Objective This study aimed to evaluate the impact of an intervention strengthening the continuum of care of child wasting from prevention, screening, and referral to treatment in Mali. Methods A two-arm cluster-randomized controlled trial was conducted using two study designs to evaluate impact and pathways: i) a longitudinal study of children enrolled at 6 months (n=2,324) with monthly follow-up for 3–6 months to assess wasting prevalence (primary outcome); ii) a longitudinal study of all children 6–23 months admitted to outpatient therapeutic programs (OTP; n=7,104) assessing recovery and adherence. Additional OTP coverage surveys were conducted at the end of the study. In both study arms, nutrition activity support groups (NASG) screened children for wasting and provided caregiver behavior change communication (BCC). The intervention arm additionally received small-quantity lipid-based nutrient supplements (SQ-LNS), child-centered BCC, family-led screening, and follow-up on referred wasting cases to support OTP admission and adherence. Results The intervention did not impact wasting prevalence but reduced the incidence of wasting (relative risk (RR): 0.80, 95% confidence interval (CI): 0.64, 0.99) and severe acute malnutrition (SAM) (RR: 0.71, 95%CI: 0.57, 0.89). The intervention significantly increased wasting screening coverage by 37 pp (95%CI: 31, 44) and SAM treatment coverage by 15 pp (95%CI: 0.35, 30). No impacts of the intervention on OTP recovery or adherence were found. NASGs often replaced the monthly home visits with community gatherings to deliver the intervention. NASGs also often distributed SQ-LNS to children they identified with wasting instead of referring them to the OTP. Conclusions Strengthening the continuum of care of wasting through community groups reduced the incidence of wasting and SAM and improved screening coverage, which translated into a modest gain in SAM treatment coverage.

Consumption of fruits and vegetables by types and sources across urban and rural Senegal

This paper analyzes the consumption of fruits and vegetables (FV) in Senegal by: (1) urban and rural areas; (2) FV types (African-indigenous vs non-indigenous); (3) sources of FV (imports, purchases and own-production).The authors undertake descriptive and regression analyses on consumption of FV sourced from purchases, own-production and gifts. The data come from primary surveys in 2017/2018 of 6,328 rural and urban households in Senegal.The analysis showed that FV are important in urban and rural food consumption. A stunning 76% of rural FV consumption is from purchases, showing the importance of FV supply chains even into and among rural areas. Only 12% of national FV consumption is from imports. Most FV consumption in rural and urban areas is now of non-indigenous FV; African-indigenous FV have a minor share.A limitation of this paper is that it uses a cross-sectional dataset.There are few national survey-based studies of FV consumption in Africa. This is the first to disaggregate FV consumption between primary versus secondary cities and rural towns, and rural areas close to and far from cities, in such detail regarding types and sources of FV as outlined in the findings. The regressions contribute by including determinants beyond income, including gender, employment, spatiality and education.

Rapport inventaire, les systèmes alimentaires au Sénégal

Depuis la pandémie de COVID-19 et plus récemment la crise russo-ukrainienne, la problématique de construire des systèmes alimentaires résilients et durables est devenue une urgence pour la plupart des pays d’Afrique au Sud du Sahara (ASS) dont le Sénégal. Très récemment, le Gouvernement du Sénégal à travers le Ministère de l’Agriculture de l’Équipement Rural et de la Souveraineté Alimentaire (MAERSA) a validé le Programme Alimentaire pour la Souveraineté Alimentaire Durable (PASAD 2021-2025). Malgré tout, les gouvernements sont confrontés de façon générale au défi de garantir que les systèmes alimentaires offrent à leurs populations de multiples avantages et ceci de manière efficace, équitable et durable. Néanmoins, les politiques restent encore souvent déconnectées et ainsi génèrent des résultats suboptimaux. Pour y remédier, un changement de paradigme ainsi qu’un renforcement des capacités institutionnelles et humaines tant au niveau national et infranational sont nécessaires afin de pouvoir formuler et implémenter des interventions programmatiques réellement intégrées. Et même si, au niveau local, des innovations transforment déjà les systèmes alimentaires locaux en les rendant plus résilients face aux multiples chocs, la déconnexion entre ces dynamiques locales, d’une part, et les processus politiques et les engagements d’investissement du secteur public, d’autre part, demeure. L’objectif global de ce rapport inventaire est de présenter les systèmes alimentaires au Sénégal en passant en revue les différentes définitions, caractéristiques et cadres conceptuels théoriques, les principales politiques alimentaires implémentées au fil des années, les initiatives nationales récemment entreprises ainsi qu’une identification des gaps de connaissance et des mécanismes politiques. De façon générale, ce rapport rentre dans le cadre d’une recherche collaborative entre l’IFPRI et l’ISRA/BAME qui vise à renforcer les capacités et les politiques sénégalaises pour une transformation durable et équitable de ses systèmes alimentaires.
