BACKGROUND AND PURPOSE: Few data on obesity exist on Sub-Sahara population in Africa. This study investigated the prevalence of obesity and Body Mass Index (BMI) percentile and quartiles in accordance with sex and age in adult residents of the historic ancient semi-urban community of Ile-Ife, South-West, Nigeria. MATERIALS AND METHODS: 2097 adults aged 21 years and above were recruited into the door-to-door survey through a multi-stage cluster sampling technique. The World Health Organization (WHO) criteria based on BMI was used in the definition of overweight and obesity. Height and weight were measured using standardized procedures. RESULTS: The mean age and BMI of the participants were 44.2 years and 24.2 Kg/m2 respectively. Although age-matched; the females had higher BMI values compared to males (23.8 vs. 24.5 Kg/m2). The overall crude prevalence of overweight (25.0-29.9 Kg/m2) and obesity (>30 Kg/m2) were 20.3% and 12.5% respectively. The rates of overweight (17.9 vs. 22.1 Kg/m2) and obesity (9.7 vs. 14.5 Kg/m2) were both higher in women than men. Obesity increased across age gradient from young to old adults; peaking in the 60-69-year age group. The first to fourth BMI quartiles were = 20.4 Kg/m2, 20.5-24.1 Kg/m2, 24.2-25.2 Kg/m2, = 25.3 Kg/ m2 respectively in the study population. At all ages; more females (32.4%) than males (24.7%) were placed within fourth BMI quartile. The 95th percentile BMI in the study population was 33.4 Kg/m2. CONCLUSION: Overweight and obesity are common in Nigerians, particular among females and elderly. The prevalence estimates of overweight and obesity in Nigerians is comparable with prevalence among Blacks in other populations.
