In Ethiopia, adolescents have the lowest mortality, and, therefore, are of low priority for nutrition interventions. However, the prevalence of malnutrition and anemia remains high in adolescent girls. Pulse crops are important in Ethiopiaˈs small landholders’ agriculture practices offering enhanced food security. Using a cross‐sectional design, our IDRC‐CIDA community based study assessed the nutrition status, pulse consumption patterns, indigenous knowledge, and food security among adolescent girls (n=188, 15–19 y). The prevalence of stunting and underweight were 31% and 30%, respectively. The intakes of energy, calcium, vitamin C and zinc were 70%, 13%, 5% and 65% of requirements, respectively. From pulse foods, lentils (85%) haricot bean (59%), peas (51%), faba bean (36%) and chick pea (29%) were consumed once or more than once per day. The nutrient contribution of pulses for iron, protein, zinc and fiber was 10%, 20%, 80% and 18% respectively. For household food security, 13% were secure, 17% were mildly insecure, 54% were moderately insecure and the remaining 16% severely insecure. Girls were shorter than the 2007 WHO standards and the diets were grossly deficient in energy and other nutrients; yet, pulse foods offered a significant contribution to nutrient intake. The dietary practices, particularly the girls’ avoidance of milk and yogurt, contribute to the nutrient deficiencies. Programs to support adequate nutrition for adolescents would provide for a healthy transition to adulthood and be a step towards breaking the cycle of intergenerational malnutrition.
