One of the main reasons of MS is obesity. For this reason, intervention for MS is focused on obesity control based on weight loss and lower BMI. However, there is disconnection between diagnosis and intervention of MS because of different usage of indices (waist circumference and BMI). Moreover, previous studies have shown that higher muscle mass has preventive role on MS, but muscularity have not been considered in the population basis by using index. Comprehensive approach on obesity considering muscularity as well as adiposity would help make better treatment for MS. This study aimed to see the association of body composition indices and MS to consider muscularity regarding MS in Korean adult population. Methods : Information of health screening results from the National Health Insurance Service in 2010, 2013, and 2016 was used as dataset. Total number of dataset is 2,993,760. From the dataset, body mass index (BMI), waist-to-body height ratio (W/BH), and body mass-to-waist ratio (BM/W) were calculated. MS was identified according to the modified definition of MS from ATP III and IDF. Body composition indices were compared by sex, year, and age groups. Correlation of each indices, and association between indices and MS were statistically analyzed. In addition, ROC curve and AUC measurements were compared with different models. Results : The results of the logistic regression analysis showed higher association of BMI and MS when model included both BMI(OR:1.23) and BM/W(OR:0.17) as independent variables compared to when model included only BMI(OR:1.20), and AUC increased as well. Especially younger female group under 60 had the highest AUC(85.7%), and female had higher AUC compared to male. Different pattern of BMI, W/BH, and BM/W were shown by sex, year, and age groups. Especially male showed higher BMI, W/BH, and BM/W in recent years. Difference between male and female was also shown in the association between BM/W and MS components by odds ratio. In female group, BM/W showed consistent inverse association between BM/W and MS including its components. Conclusion : Applying BM/W ratio which represents muscularity in addition to BMI is more effective for better explanation of MS. For the preventive role of muscularity in MS, muscle strengthening exercise is required for the prevention and intervention of MS especially for female. Considering muscularity by BM/W ratio can improve accessibility of health information and contribute to the paradigm shift in obesity.์—ฐ๊ตฌ๋ฐฐ๊ฒฝ : ํ•œ๊ตญ์—์„œ ๋Œ€์‚ฌ์ฆํ›„๊ตฐ์˜ ๋ฐœ์ƒ์€ ๊พธ์ค€ํžˆ ์ฆ๊ฐ€ํ•˜๊ณ  ์žˆ๋‹ค. ๋Œ€์‚ฌ์ฆํ›„๊ตฐ์˜ ์ฃผ์š” ์›์ธ ์ค‘ ํ•˜๋‚˜๋Š” ๋น„๋งŒ์œผ๋กœ, ๋Œ€์‚ฌ์ฆํ›„๊ตฐ์— ๋Œ€ํ•œ ์ค‘์žฌ๋Š” ์ฒด์ค‘ ๊ฐ๋Ÿ‰๊ณผ BMI ๊ฐ์†Œ๋ฅผ ๋ชฉ์ ์œผ๋กœ ํ•œ ๋น„๋งŒ ๊ด€๋ฆฌ ์ค‘์‹ฌ์œผ๋กœ ์ด๋ฃจ์–ด์ง€๊ณ  ์žˆ๋‹ค. ํ•˜์ง€๋งŒ ๋Œ€์‚ฌ์ฆํ›„๊ตฐ์˜ ์ง„๋‹จ๊ณผ ์ค‘์žฌ ๋‹จ๊ณ„์—์„œ ๊ฐ๊ธฐ ๋‹ค๋ฅธ ์‹ ์ฒด์ง€์ˆ˜(ํ—ˆ๋ฆฌ๋‘˜๋ ˆ, BMI)๋ฅผ ์‚ฌ์šฉํ•จ์œผ๋กœ์จ ๋ฐœ์ƒํ•˜๋Š” ๊ดด๋ฆฌ๊ฐ€ ์กด์žฌํ•œ๋‹ค. ์ด์™€ ๋”๋ถˆ์–ด ์„ ํ–‰์—ฐ๊ตฌ์— ์˜ํ•˜๋ฉด ๊ทผ๋ ฅ์ด ๋Œ€์‚ฌ์ฆํ›„๊ตฐ์„ ์˜ˆ๋ฐฉํ•˜๋Š” ํšจ๊ณผ๋ฅผ ๊ฐ€์ง„๋‹ค๊ณ  ๋ฐํ˜€์ ธ ์žˆ์œผ๋‚˜, ํ˜„์žฌ ์ง€์ˆ˜๋ฅผ ์‚ฌ์šฉํ•˜์—ฌ ์ธ๊ตฌ์ง‘๋‹จ์„ ๋Œ€์ƒ์œผ๋กœ ๊ทผ๋ ฅ์„ ๊ณ ๋ คํ•˜๊ณ  ์žˆ์ง€๋Š” ์•Š๋‹ค. ๋”ฐ๋ผ์„œ ์ง€๋ฐฉ๋ฟ๋งŒ ์•„๋‹ˆ๋ผ ๊ทผ๋ ฅ์— ๋Œ€ํ•œ ์ข…ํ•ฉ์ ์ธ ๊ณ ๋ ค๋ฅผ ํฌํ•จํ•˜๋Š” ๋น„๋งŒ์— ๋Œ€ํ•œ ์ ‘๊ทผ์ด ๋Œ€์‚ฌ์ฆํ›„๊ตฐ ๊ด€๋ฆฌ๋ฅผ ์œ„ํ•ด ํ•„์š”ํ•˜๋‹ค. ๋ณธ ์—ฐ๊ตฌ์˜ ๋ชฉ์ ์€ ํ•œ๊ตญ์„ฑ์ธ์„ ๋Œ€์ƒ์œผ๋กœ ๊ทผ๋ ฅ์„ ๊ณ ๋ คํ•˜์—ฌ ์‹ ์ฒด์ง€์ˆ˜์™€ ๋Œ€์‚ฌ์ฆํ›„๊ตฐ๊ณผ์˜ ๊ด€๊ณ„๋ฅผ ์‚ดํŽด๋ณด๊ณ , ๋” ํšจ๊ณผ์ ์ธ ๋น„๋งŒ๊ณผ ๋Œ€์‚ฌ์ฆํ›„๊ตฐ ๊ด€๋ฆฌ์— ๊ธฐ์—ฌํ•˜๊ณ ์ž ํ•˜๋Š” ๊ฒƒ์ด๋‹ค. ์—ฐ๊ตฌ๋ฐฉ๋ฒ• : ๋ณธ ์—ฐ๊ตฌ๋Š” ๊ตญ๋ฏผ์—ฐ๊ธˆ๊ณต๋‹จ์˜ 2010, 2013, 2016๋…„ ๊ฑด๊ฐ•๊ฒ€์ง„์ž๋ฃŒ๋ฅผ ์ด์šฉํ•˜์˜€๋‹ค. ์ „๊ตญ ๊ตญ๋ฏผ์—ฐ๊ธˆ ๊ฐ€์ž…์ž ๋ฐ ํ”ผ๋ถ€์–‘์ž ์„ฑ์ธ์„ ๋Œ€์ƒ์œผ๋กœ ํ•œ ๋‹จ๋ฉด์—ฐ๊ตฌ๋กœ ์ด 2,993,760๋ช…์˜ ์ž๋ฃŒ๋ฅผ ์ˆ˜์ง‘ํ•˜์˜€๋‹ค. ์ž๋ฃŒ์›์œผ๋กœ๋ถ€ํ„ฐ ์ฒด์งˆ๋Ÿ‰์ง€์ˆ˜(BMI)์™€ ํ—ˆ๋ฆฌ๋‘˜๋ ˆ-ํ‚ค ๋น„์œจ(W/BH), ์ฒด์ค‘-ํ—ˆ๋ฆฌ๋‘˜๋ ˆ ๋น„์œจ(BM/W)์„ ๊ณ„์‚ฐํ•˜์˜€๊ณ , ์‹ ์ฒด์ง€์ˆ˜์™€ ๋Œ€์‚ฌ์ฆํ›„๊ตฐ ์ง„๋‹จ๊ธฐ์ค€ ๋ณ€์ˆ˜๋ฅผ ์ค‘์‹ฌ์œผ๋กœ ๋ถ„์„ํ•˜์˜€๋‹ค. ๋Œ€์‚ฌ์ฆํ›„๊ตฐ์€ ATP III์™€ IDF์˜ modified ๊ธฐ์ค€์„ ์‚ฌ์šฉํ•˜์—ฌ ์ง„๋‹จํ•˜์˜€๋‹ค. ์‹ ์ฒด์ง€์ˆ˜๋Š” ์„ฑ๋ณ„๊ณผ ๋…„๋„, ์—ฐ๋ น๊ทธ๋ฃน์œผ๋กœ ๊ตฌ๋ถ„ํ•˜์—ฌ ๋น„๊ตํ•˜์˜€๋‹ค. ์ง€์ˆ˜์™€ ๋Œ€์‚ฌ์ฆํ›„๊ตฐ ๊ฐ„์˜ ์—ฐ๊ด€์„ฑ ๋ถ„์„์„ ์œ„ํ•ด ๋กœ์ง€์Šคํ‹ฑ ํšŒ๊ท€๋ถ„์„์„ ์‹ค์‹œํ•˜์˜€๋‹ค. ์ดํ›„ ROC ๊ณก์„ ๊ณผ AUC ๊ฐ’์„ ํ†ตํ•ด ํšŒ๊ท€๋ถ„์„ ๋ชจ๋ธ์„ ๋น„๊ตํ•˜์˜€๋‹ค. ์—ฐ๊ตฌ๊ฒฐ๊ณผ : ์—ฐ๊ตฌ๊ฒฐ๊ณผ์— ๋”ฐ๋ฅด๋ฉด, ๋กœ์ง€์Šคํ‹ฑ ํšŒ๊ท€๋ถ„์„์—์„œ ์ข…์†๋ณ€์ˆ˜๋กœ ๋Œ€์‚ฌ์ฆํ›„๊ตฐ์— ๋Œ€ํ•ด ๋…๋ฆฝ๋ณ€์ˆ˜๋กœ BMI(OR:1.23)์™€ BM/W(OR:0.17)๊ฐ€ ํ•จ๊ป˜ ํฌํ•จ๋˜์—ˆ์„ ๋•Œ BMI๋งŒ ํฌํ•จํ•œ ๋ชจ๋ธ(OR:1.20)์— ๋น„ํ•ด BMI์™€ ๋Œ€์‚ฌ์ฆํ›„๊ตฐ์˜ ์—ฐ๊ด€์„ฑ์ด ๋” ๋†’์•„์ง€๊ณ  ๋” ๋†’์€ AUC ๊ฐ’์„ ๊ฐ€์กŒ๋‹ค. ํŠนํžˆ 60์„ธ ์ดํ•˜ ์ Š์€ ์—ฌ์„ฑ์˜ ๊ฒฝ์šฐ ๊ฐ€์žฅ ๋†’์€ AUC ๊ฐ’(85.7%)์„ ๋ณด์˜€์œผ๋ฉฐ, ๋‚จ์„ฑ์— ๋น„ํ•ด ์—ฌ์„ฑ์ด ๋” ๋†’์€ AUC๋ฅผ ๋ณด์˜€๋‹ค. ์„ฑ๋ณ„, ๋…„๋„, ์—ฐ๋ น๊ทธ๋ฃน๋ณ„๋กœ ์‹ ์ฒด์ง€์ˆ˜๋ฅผ ๋น„๊ตํ–ˆ์„ ๋•Œ์—๋„ ๋‚จ๋…€ ๊ฐ„์— ํฐ ์ฐจ์ด๋ฅผ ๋ณด์˜€์œผ๋ฉฐ, ํŠนํžˆ ๋‚จ์„ฑ์˜ ๊ฒฝ์šฐ ์ตœ๊ทผ์œผ๋กœ ์˜ฌ์ˆ˜๋ก BMI๊ฐ€ ๋†’์ง€๋งŒ W/BH์™€ BM/W๋„ ๋™์‹œ์— ๋†’์•„์ง์„ ํ™•์ธํ–ˆ๋‹ค.
