Nutritional status, hospitalization and mortality among patients with sickle cell anemia in Tanzania

Abstract

Background Reduced growth is common in children with sickle cell anemia, but few data exist on associations with long-term clinical course. Our objective was to determine the prevalence of malnutrition at enrolment into a hospital-based cohort and whether poor nutritional status predicted morbidity and mortality within an urban cohort of Tanzanian sickle cell anemia patients.Design and Methods Anthropometry was conducted at enrolment into the sickle cell anemia cohort (n=1,618; ages 0.5–48 years) and in controls who attended screening (siblings, walk-ins and referrals) but who were found not to have sickle cell anemia (n=717; ages 0.5–64 years). Prospective surveillance recorded hospitalization at Muhimbili National Hospital and mortality between March 2004 and September 2009.Results Sickle cell anemia was associated with stunting (OR=1.92, P
