Abstract

The purpose of this study was to compare Obesity Age (OA) and chronological age, to calculate Obesity Age (OA), which gauges the state of obesity, and to analyze presented factors of obesity using expectant factors on middle-aged obese women. The subjects were one hundred twenty seven middle-aged obese women ($49.6\pm7.3$ yr, BMI $29.41\pm2.9$, fat $36.8\pm4.6%$) who participated in different weight loss programs three times. The body composition, physical fitness, blood pressure and blood were measured before the weight loss programs. Informed consent was obtained from all subjects before enrollment in the study. The regression equation is as follows: (1) OAS (Obesity Age Score)=$0.106*X_1+0.035*X_2+0.048*X_3+0.041*X_4+0.003*X_5-0.037*X_6-10.667$ ($X_1$: BMI, $X_2$: weight, $X_3$: %fat, $X_4$: WC, $X_5$: TG, $X_6$: $VO_{2max}$), (2) OA (Obesity Age)=7.3*OAS+49.6*(-1), (3) Z (correction factor)=(CA-49.6)(1-0.03), (4) OAc (corrected Obesity Age)=1.03*CA-7.3*OAS+1.47. The comparison of corrected Obesity Age (OAc) and chronological age did not have any differences, and the average of the OAc was close to chronological age. The correlation coefficient between the OAc and chronological age was r=0.724 (p<0.05). The equation can be utilized for middle-aged obese women, because it could evaluate the obesity-related factors by including BMI, body weight, %fat, waist circumference, triglycerides and $VO_{2max}$.

본 연구에서는 중년비만여성을 대상으로 비만의 발생요인으로 예상되는 요인을 이용하여 비만의 상태를 연령 척도화하여 비만연령(Obesity Age: OA)이라는 연령 추정식을 산출함과 동시에 비만도(비만연령)를 실제의 역연령과 검토하였고 비만연령의 추정식은 다음과 같다. OAS (Obesity Age Score)=$0.106*X_1+0.035*X_2+0.048*X_3+0.041*X_4+0.003*X_5-0.037*X_6-10.66$ (1) ($X_1$: BMI, $X_2$: 체중, $X_3$: 체지방률, $X_4$: 배둘레, $X_5$: 중성지방, $X_6$: $VO_{2max}$) OA (Obesity Age)=7.3*OAS+49.6*(-1) (2) Z=(CA-49.6)(1-0.03) (3) OAc (Obesity Age corrected)=1.03*CA-7.3*OAS+1.47 (4) 그리고 역연령과 추정된 비만연령(Obesity Age corrected: OAc)의 비교에서는 유의한 차이를 나타내지 않아 타당성이 확인되었으며, 총 6개의 측정항목으로 구성된 비만연령을 통해 비만자 개개인의 비만건강도(상태)를 용이하게 평가할 수 있을 것으로 기대하며, 추후에는 다른 집단에서의 적용가능 여부를 알아보기 위해 교차타당성을 검토해야할 것이라고 사료된다.
