Abstract

Malnutrition remains a major public health issue in Sub-Saharan Africa, with one-third of all malnourished children residing in the region. In Malawi, 37.1% of children under five are stunted, and 63% are anaemic. Poor diets and poverty contribute significantly. Legumes, being rich in protein, fibre, and micronutrients, offer a sustainable food-based approach to improve child nutrition and support local agriculture. This study aimed at assessing the association between legume consumption and nutritional status in children aged 6-59 months in rural Malawi. A community-based cross-sectional study was conducted in Mzimba, Mchinji, and Mangochi districts, involving 1275 children. Data were collected on dietary intake, socioeconomic status, and anthropometry using semi-structured questionnaires. Nutritional status was determined using WHO Anthro, and associations were analysed using logistic regression in Stata. Prevalence of stunting was 42.8%, underweight 17.4%, and wasting 8.4%. Over half of the children did not consume legumes. Pigeon pea consumption significantly reduced odds of wasting (AOR = 0.14), and common beans were associated with lower odds of both wasting and stunting. Conversely, groundnut consumption was linked to increased underweight (AOR = 1.68). Animal food consumption was associated with lower underweight but higher odds of wasting. Legume consumption showed both protective and adverse associations with child malnutrition. In conclusion, this study has shown that promoting dietary diversity and appropriate legume use could enhance nutrition outcomes. Findings highlight the potential of legumes in addressing undernutrition but also the need for targeted nutrition education and interventions in rural Malawi.
