Acute malnutrition remains a major public health problem in the Central African Republic, particularly in the NanaGribizi region. To improve early management and prevent nutritional deterioration, an integrated communitybased approach has been implemented. The study aims to assess the impact of this approach on the prevention and management of malnutrition. The study, conducted in Ouandago in the commune of NanaOuta, is qualitative in nature. It involved the local community and health personnel. The sample included various groups: caregivers of malnourished children, pregnant and breastfeeding women, heads of households, community leaders, model mothers, community volunteers, and health workers. Data were collected from the malnutrition treatment register and through interviews, then entered Excel 2016 and analyzed using Epi Info version 7. The age of malnourished children ranged from 6 to 55 months, with boys being predominant in both periods (54% and 58.3%). Comparing the nutritional situation before the integration of the community approach in 2021 with that of 2023—two years after implementation, the number of malnutrition cases significantly decreased, dropping from 871 in 2021 to 503 in 2023. The prevalence of severe acute malnutrition fell from 3.1% to 1.7%, moderate acute malnutrition from 12.57% to 5.9%, and global acute malnutrition from 15.6% to 7.5%. The communitybased approach clearly improves nutritional care. Thanks to Model Mothers and community volunteers, good nutritional practices have improved, and the prevalence of acute malnutrition has decreased.

Malnutrition, particularly among pregnant women, represents a major public health challenge in Burkina Faso due to its negative impacts on maternal and child health. This study aimed to analyze the level of knowledge of pregnant women attending antenatal care (ANC) regarding maternal nutrition. It specifically assessed their knowledge of the three food groups, the principles of a balanced diet, the consequences of malnutrition during pregnancy, and iron–folic acid supplementation. This was a quantitative, crosssectional, and descriptive study with prospective data collection, conducted from March 1 to April 30, 2024, at the Guimbi Ouattara Primary Health Care Center (CSPS) in BoboDioulasso. Data were collected using the Kobocollect application and analyzed with SPSS and Excel software. A composite indicator, the Maternal Nutrition Knowledge Index (MNKI), based on five domains, was developed to facilitate the analysis and interpretation of the results. The findings indicate a moderate overall level of maternal nutrition knowledge, with a global MNKI of 62.8%. Although most participants demonstrated good practical skills in composing a balanced meal, significant gaps remain regarding the identification of food groups, the recommended duration of iron–folic acid supplementation during the postpartum period, and the understanding of the consequences of inadequate nutrition during pregnancy. Women with no formal or low educational attainment, those living outside the health facility catchment area, and primigravidae in early pregnancy emerged as the most vulnerable groups, highlighting the need to strengthen targeted nutrition education and behavior change communication interventions.
