This case study examines solutions to infant malnutrition in Africa from an interdisciplinary perspective, identifying factors that directly or indirectly influence practices involved in feeding infants from birth to age 3 in Maradi, Niger. The study begins by providing a conceptual framework and description of the approach used in the analysis, emphasizing the need for analysis at the city, household, and individual child levels. The study then provides a detailed analysis of the city environment, focusing on demography, health, social life and organization, and economics. Various situations in the urban population, including geographic disparities and family standards of living, are discussed. The study examines food and diet-related behavior, specifically describing food preparation, sources of food, and social activities related to food. Detailed analysis of mother and child relationships includes descriptions of infants' daily food intakes and mothers' behavior toward their infants. The study concludes by summarizing constraints and strategies mentioned throughout the study, and suggests general guidelines for a comprehensive approach to addressing the problem of infant malnutrition in urban Africa.
