The relationship between childhood obesity and adult obesity had been demonstrated. Moreover, there are reports showed childhood obesity lnks to adult cardiovascular disease mortality. However, there are few longitudinal follow up studies aimed at the change of body indices from childhood to adulthood in Taiwan. Materials and Methods: The study population was all the freshman entering one junior high school in Northern part of Taiwan in 1985. The measurements of body height, body weight, and body mass index were performed longitudinally for three times at the first year of junior high school (about 13 years old), the third year of junior high school (about 15 years old), and adulthood (about 27 years old). Based on BMI levels, participants were classified into overweight or not, obese or not, and overweight and obese or not. Logistic regression analysis was used as the statistical method for the association analysis of adolescent obesity with young adulthood obesity. Results: A total of 384 participants (male: 178, female: 206) were included in 1985, and the complete follow up data for three measurements were available in 112 participants (male: 61, female: 51). Using logistic regression analysis with adulthood obesity as the outcome variable, odds ratio (OR) of adulthood overweight and obesity of participants with overweight and obesity at the first year of junior high school survey versus without was 14.3 (95% confidence interval: 2.70 – 75.2) in male and 57.3 (4.78 – 687.6) in female. The OR of adulthood overweight and obesity of participants with overweight and obesity at the third year of junior high school survey versus without was 13.6 (3.17 – 58.1) in male and 8.36 (1.18 – 59.4) in female. The change of body height, body weight, and body mass index between the investigations at the first year and the third year were also used as the indepent variables for analysis. The results showed that the change of body weight (OR = 1.11, 1.02 – 1.21) was positively associated with adulthood obesity among all participants, and the change of body height (OR = 0.83, 0.72 – 0.97) were negatively associated with adulthood obesity in males. Conclusion: The results demonstrated that obese adolescents are tended to become obese adults in our country even our obesity cut-off points are different from other races. Also, the change of body weight and body height is important in obesity prevention program. The government should provide proper children and adolescents growth standards including body height, body weight, and body mass index among different ages our children and adolescents, and build effective obesity control programs.
