Table 9 Sensitivity, specificity, and odds ratios of the selected cutoff point for BMI values at the 85th percentile at 13–15 y old for identifying overweight at age 35 y

From: Impact of obesity on glucose and lipid profiles in adolescents at different age groups in relation to adulthood

  1. Specificity = 88 of 110 subjects, Sensitivity: 14 of 18 subjects. An odds ratio of 12.8 means that the risk of 13–15 years old adolescents with a BMI ≥ 85th percentile of becoming an overweight or obese adults at 35 y old is 12.8 times higher than in those with a BMI < than 85th percentile
