Abstract
To evaluate the degree of obesity based on differential combinations of BMI and body fat ratio, and thereby to obtain the comprehensive determination of coronary heart disease risk factors. The present study was conducted among 3,731 individuals(male; 2,312, female; 1,419) who underwent general health checkup in the general health promotion center in a university hospital during 2-year period from Jan. 2008 to Dec. 2009. Based on the obesity categories from combinations of BMI and body fat ratio, 30.2% were "normal", 8.9% were "seemingly obese", 31.2% were "occult obese", and 29.8% were "obese". By sexual comparison, the proportion of "normal" and "seeming obese" individuals were higher in men than women, while "occult obese" and "obesity" individuals were preponderant in women compared to men. By age, the proportion of "obesity" individuals were higher in the 40' and 50's than in 30's and 60's. Based on the association between obesity categories and each of CRF, SBP, DBP, TC, HDL-C, LDL-C and TG was significantly higher in "seeming obese" and "obesity" group than in "normal" group, but SBP, TC and LDL-C was significantly higher in "occult obese" and "obesity" group than in "normal" group. For odds ratios of each of CRF for obesity categories, it was higher in "obesity" group, "seeming obese" group, "occult obese" group than in "normal" group in that order.
본 연구는 BMI와 체지방율을 이용하여 비만도를 평가하고, 관상동맥질환위험인자들과 비만도와의 관련성을 검토하고자 2008년 1월부터 2009년 12월까지 2년 동안에 한 대학병원 건강검진센타에 내원하여 종합건강검진을 받았던 30세 이상의 일반 시민 3,731명(남자 2,312명, 여자 1,419명)을 분석대상으로 하였다. 연구결과 BMI와 체지방율을 대비하여 평가한 비만도는 "정상군"30.2%, "외관형 비만군"8.9%, "체지방형 비만군"31.2%, "비만군"29.8%이었다. 남성은 여성에 비해 "정상군"과 "외관형 비만군"의 비율이 높은 반면, 여성은 남성에 비해 "체지방형 비만군"과 "비만군"의 비율이 유의하게 높았으며, 연령별로는 40대와 50대 연령군에서 "비만군"의 비율이 유의하게 높았다. CRF치의 변화에서 SBP, DBP, TC, HDL-C, LDL-C 및 TG는 "정상군"보다 "외관형 비만군"과 "비만군"에서 유의하게 높았고, SBP, TC 및 LDL-C는 "정상군"보다 "체지방형 비만군"과 "비만군"에서 유의하게 높았다. 비만도에 따른 CRF 증가의 위험비는 "정상군"에 비해 "비만군"에서 가장 높았으며, 다음은 "외관형 비만군", "체지방형 비만군"의 순으로 위험비가 높아졌다.
