The investigators are studying how to prevent malnutrition in children with sickle cell disease (SCD) in northern Nigeria. Community health workers will teach mothers about nutritious local foods that might help children grow better than the usual advice from doctors. The investigators will enroll 148 children with SCD aged 6 to 18 months old. The investigators will determine if their weight and diet improve and check for low vitamin A levels. This information will help us find better ways to improve growth for children with SCD.
Despite efforts to improve nutrition, 45% of under-5 mortality is at least partially attributable to malnutrition. Children with SCD have high nutrient demands and energy expenditures with a risk of impaired growth. The investigators will test the hypothesis that maternal nutrition education on locally available nutrient-dense foods will lead to improved childhood growth compared to standard pediatrician-delivered nutrition counseling. The research will involve a randomized controlled trial with 148 children aged 6 to 18 months with SCD, assessing changes in weight-for-age z-scores and dietary adequacy, as well as determining the prevalence of vitamin A deficiency. These preliminary findings will inform evidence-based interventions for the primary prevention of malnutrition (underweight and vitamin A deficiency) in children with SCD.

Change in weight for the for-age z score.
Mean change in weight-for-age z score in the randomly allocated groups, standard care versus the novel maternal intervention. This is a continuous outcome where a higher z-score indicates a positive outcome.
Time frame: 24 weeks
Percentage of children receiving the minimum dietary adequacy
percentage of young children with a World Health Organization-defined minimum acceptable diet based on dietary diversity and feeding frequency
Time frame: 24 weeks
Prevalence of vitamin A deficiency
Continuous unadjusted and inflammation-adjusted retinol levels and the corresponding prevalence of vitamin A deficiency
Time frame: 24 weeks
