In Chad, as in most sub-Saharan African countries, the nutritional situation remains a major concern, and is an underlying cause of many other health problems. The aim of this study is to assess the nutritional status of children aged 6 to 59 months in the provinces of Logone Occidental and Wadi-Fira, in order to contribute to a better management of nutritional problems. The study was carried out between August 16 and October 10, 2022, and involved 207 children aged 6 to 59 months in Wadi-Fira, and 63 aged 6 to 59 months in Logone Occidental. Data collection was carried out using a questionnaire and measurements to collect data on the children's socio-demographic characteristics and anthropometry. Analysis of the children's nutritional status was based on the z-score of nutritional indices and edema according to 2006 WHO references. Analysis of the results showed that the prevalence of global acute malnutrition is 18.84%, chronic malnutrition affects 30.9% and underweight affects 32.9% of children in Wadi Fira. In Logone Occidental, about 1/10 child (9.20%) suffers from acute malnutrition, 33.6% from chronic malnutrition and 22.8% from underweight. In Wadi-Fira, the nutritional situation is considered critical, with more than one child on 15 suffering from global or moderate acute malnutrition. In Logone Occidental, the nutritional situation is precarious for both forms of acute malnutrition. The nutritional situation in both provinces needs a reinforcement of current actions in the fight against malnutrition.
