Abstract

Background: This study aimed to analyze the medical expenses paid by the Korea National Health Insurance Service (KNHIS) according to body mass index (BMI) in Korean adults.

Methods: We included 1,170,464 adults (623,498 men and 546,966 women) aged ≥19 years from the KNHIS-National Sample Cohort database (2016 to 2019) after excluding individuals with cancer. Average yearly medical expenses per person and average yearly medical expenses (Korean won [KRW], 1 United States dollar=1,292 KRW) by BMI classification were assessed according to age and sex. The medical expenses comprised those for medication, outpatient department (OPD), and hospitalization. The means and 95% confidence intervals were analyzed using a two-factor t-test.

Results: The average yearly medical expenses per person increased significantly as BMI increased in women but not in men. The average yearly medical expenses were highest in the highest quintile of BMI in all age groups and in women. Even though BMI showed a U-shape association with medical expenses for OPD and hospitalization in young and elderly individuals, medical expenses for medication in all age groups and those for OPD and hospitalization in middle-aged individuals increased sharply in the highest quintile of BMI.

Conclusion: All types of medical expenses increased in higher BMI groups in all Korean adults, particularly in women, and those with the highest BMI had the highest direct medical expenses. Strategies for preventing and managing obesity are warranted to minimize the burden from medical expenses.

研究背景本研究旨在根据韩国成年人的体重指数（BMI）分析韩国国民健康保险服务（KNHIS）支付的医疗费用：在排除癌症患者后，我们纳入了 KNHIS-全国抽样队列数据库（2016 年至 2019 年）中年龄≥19 岁的 1,170,464 名成年人（男性 623,498 人，女性 546,966 人）。根据年龄和性别评估了每人每年平均医疗费用和按体重指数分类的平均每年医疗费用（韩元[KRW]，1美元=1,292韩元）。医疗费用包括药物、门诊和住院费用。采用双因素 t 检验分析了平均值和 95% 的置信区间：女性每人每年的平均医疗费用随着体重指数（BMI）的增加而显著增加，但男性则没有。在所有年龄组和女性中，BMI最高五分位数的年均医疗费用最高。尽管体重指数与年轻人和老年人的门诊和住院医疗费用呈 U 型关系，但在体重指数最高的五分位数中，所有年龄组的药物医疗费用以及中年人的门诊和住院医疗费用都急剧增加：结论：在所有韩国成年人中，体重指数越高的人群各类医疗费用越高，尤其是女性，体重指数最高的人群直接医疗费用最高。有必要采取预防和管理肥胖症的策略，以尽量减轻医疗费用负担。
