Brief Summary

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.

Detailed Description

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.

GroupInterventionDescription
Standard Care OnlyStandard CareMothers whose infants are assigned to the control group will receive standard nutrition education from the provider at the SCD clinic during weeks 0, 8, and 16.
Standard Care plus Maternal Nutrition EducationMaternal Nutrition EducationMothers whose infants are assigned to this group will be provided individually by a community health worker during weeks 0, 8, and 16. In addition to receiving nutrition counseling, maternal nutrition education will emphasize utilizing locally available foods to enhance the nutritional well-being of young children and families, all while respecting local cultural and religious customs. To reinforce these educational messages, visual aids will be incorporated. The following educational messages will be addressed: 1. appropriate feeding frequency 2. dietary diversity using local foods 3. Complementary food preparation 4. adequate portions 5. individualized, tailored economic education regarding the cost of purchasing foods that can fill nutrient gaps (self-efficacy)

Primary Outcome Measures
NameTimeMethod
Change in weight for the for-age z score.24 weeks

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.

Secondary Outcome Measures
NameTimeMethod
Prevalence of vitamin A deficiency24 weeks

Continuous unadjusted and inflammation-adjusted retinol levels and the corresponding prevalence of vitamin A deficiency

Percentage of children receiving the minimum dietary adequacy24 weeks

percentage of young children with a World Health Organization-defined minimum acceptable diet based on dietary diversity and feeding frequency
