Abstract
Children with sickle cell anemia are vulnerable to growth deficits; thus, it would be thought that obesity would be rare among them. The objective of the study is to examine the prevalence of obesity in a sickle cell anemia population in Lagos. A random sample of children with sickle cell anemia aged 2–15 years was interviewed and anthropometric measurements including weight and height were taken. Their body mass index (BMI) was calculated. Participants were classified as obese or not obese by their BMI or weight-for-height-for-age using World Health Organization standard definitions. The overall prevalence of obesity was 2.5% and 3.8% among hemoglobin genotype SS subjects and hemoglobin genotype AA controls, respectively. The age-specific prevalence for obesity was highest among the adolescent age category in hemoglobin genotype AA controls and the childhood age category in subjects with sickle cell anemia. All the obese subjects with sickle cell anemia were from upper socioeconomic strata, while two and one of the three subjects with hemoglobin genotype AA were from upper and middle socioeconomic strata, respectively. Obesity does exist among children with sickle cell anemia in Lagos, Nigeria. Public health programs aimed at prevention and control of obesity must include children with sickle cell anemia.
