Table 2 Agreement of obesity prevalence measured by Ethiopian and WHO BMI cut-offs with obesity based on  ADP measured body fat percentage among Ethiopian adult males

From: Performance of newly developed body mass index cut-off for diagnosing obesity among Ethiopian adults

Variables n Prevalence of obesity
(a) Obesity based on ADP measured body fat > 25% for males (%) (b) Obesity based on BMI ≥ 30 kg/m2 (%) Difference (ab) (%) Kappa (c) Obesity based on Ethiopian BMI cut-off males > 22.2 kg/m2 (%) Difference (ac) (%) Kappa

  1. Kappa agreement (0 = no/poor), (0.01–0.20 = slight), (0.21–0.40 = fair), (0.41–0.60 = moderate), (0.61–0.80 = substantial), and (0.81–1.00 = almost perfect) (William et al., 2011). BMI cut-off for obesity ≥ 30 kg/m2 is the WHO cut-off [20]
