Background: Obesity is a global epidemic not just among adults but also among children and adolescents. This study described the prevalence and pattern of obesity among in-school adolescents in Ile-Ife, Osun State using two standard methods, Body Mass Index (BMI) and Waist Hip Ratio (WHR) with a view of comparing the two methods as well as identifying any correlation between the two methods. Materials and Methods: Five hundred male and female respondents, aged 10-19 years, were randomly selected through a multistage sampling technique from private and public schools in Ife Central Local Government Area. Quantitative data were collected with the aid of a pre-tested, semi-structured, self-administered questionnaire. Anthropometric measurements of respondents, BMI and WHR, were recorded. Chi square and linear regression analyses were used. Statistical significance was tested at the 5% level. Results: The prevalence of obesity was 4.2% using BMI of which 12 (57.1%) were females and nine (42.9%) were males. There was significant association between sex and BMI, χ2 = 9.490 ( P = 0.020). Using WHR, the prevalence was 37.2% of which 180 (96.8%) were females and six (3.2%) were males. There was also significant association between sex and WHR ( P < 0.001). Weak correlation ( r = 0.02) was found between BMI and WHR among the females, P = 0.043. Conclusion: There was a difference in the prevalence of obesity using the two methods. Although, the correlation between the two methods was weak among females, WHR yielded a higher prevalence for obesity with remarkable difference especially among the females. Prevention of adolescent obesity should be encouraged especially among females.
