In Ethiopia, religious fasting often involves abstaining from animal source foods. Although children are exempt from fasting, their diets are influenced by the widespread fasting practices. This study investigated the factors influencing consumption of animal source foods among young children during the Lent fasting period in western Amhara, Ethiopia. Using baseline survey data from households with children 6-23 months of age, we conducted analyses to examine the maternal and household factors associated with consumption of animal source food and the direct and indirect effects of maternal knowledge, beliefs, social norms, and livestock ownership on consumption.
