Associations of overweight and obesity with cardiometabolic risk factor clusters among Korean adolescents

This study investigated the association between overweight, obesity, and cardiometabolic risk factor clusters in Korean adolescents. We included 2182 participants (1161 boys and 1021 girls) aged 12-18 years from the Korea National Health and Nutrition Examination Survey (2016-2021). Cardiometabolic risk factors include hypertension, high low-density lipoprotein cholesterol (LDL-C) level, low high-density lipoprotein cholesterol (HDL-C) level, hypertriglyceridemia, high fasting plasma glucose level, elevated alanine aminotransferase level, and hyperuricemia. The average age was 15.1 +/- 0.1 years in both boys and girls. The proportion of subjects with >= 1, >= 2, and >= 3 cardiometabolic risk factors was 76.5%, 49.8%, and 22.7% in obese adolescents, and 60.5%, 24.0%, and 9.1%, in overweight adolescents, respectively. Compared to adolescents with underweight/normal weight, the odds ratios (ORs) and 95% confidence intervals for the clustering of cardiometabolic risk factors were at 2.76 (1.74-4.38) for >= 1; 3.75 (2.11-6.66) for >= 2; and 4.75 (1.70-13.25) for >= 3 factors in obese adolescents and 1.88 (1.26-2.81) for >= 1 factor in overweight adolescents. Overweight and obese adolescents exhibited high cardiometabolic risk clustering. Prevention and management of overweight/obesity in Korean adolescents are emerging to mitigate health risk associated with this condition.
