Abstract : For almost ten years, Mauritania has adopted the UNICEF `Integrated Young Child Feeding` program, designed to improve remarkably the nutritional health status of babies and their mothers. In this study the 3 classical malnutrition manifestations (Stunting, wasting and underweight), as well as the aggregated CIAF indicator for babies living within the south Mauritania where the child malnutrition is yet challenging problem. Plus, the influence of Awareness-Raising Campaign on the Nutritional/Health Status of babies and additionally of their mothers in these rural/semi-rural zones was assessed. As there is only a small decrease of CIAF composite indicator for the intervention group (which benefitted from awareness-raising campaign) relatively to control group (3%), the impact of the intervention campaign failed to improve remarkably the Nutritional/Health Status of babies. Also, The mothers population, which is relatively young with average age of 29 years, has a high rate of fat mass excess (higher than 35%) for both the intervention and control group, 68.3% and 63.6%, respectively. In addition, the percentage of overweighted mothers is greater for Intervention Group (2.2%) and yet absent in the Control Group. These results are probably due to strongly clouting traditions of rural Mauritanian families and also to the weaknesses of intervention campaign, clearly the need for an innovative intervention campaign capable of reducing the obesity rate among women.
