Abstract

This study was to find out the correlation between abdominal surface temperature and abdominal fat areas. CT and MRI methods have been used to assess abdominal fat area. Abdominal surface temperature according to abdominal fat area was also measured by DITI. 20 college students were selected as the subjects for the study. The results, showed that there were statistically different significance in abdominal fats measured by CT and MRI according to weight groups. Abdominal surface temperature gap were measured by DITI and there was a statistically significant difference in only T12 region. temperature gaps between weight groups were over $0.7^{\circ}C$. In conclusion, CT method is the most accurate method to measure abdominal fat. However, weak points are radiation exposure and high cost for study. The correlation between abdominal surface temperature and abdominal fat areas were strong. Therefore, DITI may be considered as useful convenient method to evaluate the abdominal obesity and clinical usefulness.

본 연구는 복부지방면적과 복부표면온도와의 상관관계를 알아보고자 연구하였다. CT와 MRI 검사을 시행하여 복부지방면적을 분석 하였고, 복부지방면적에 따른 복부표면온도는 적외선체열진단 검사로 측정하였다. 20명의 남녀 대학생을 대상으로 시행하였다. 분석 결과, CT와 MRI검사를 이용한 복부영역별 지방면적은 체중그룹과 모두 통계적으로 유의한 차이가 있었다. 복부표면온도는 T12번 부위에서만 통계적 유의성이 있었다. 체중그룹간의 복부표면 온도 차이는 $0.7^{\circ}C$이상이었다. 결론적으로, CT는 가장 정확한 복부지방 측정 방법이다. 그러나 방사선 피폭과 고가의 검사 비용이 단점이다. 본 연구에서는 복부지방면적과 복부표면온도와의 상관관계가 있는 것으로 확인되었다. 따라서 적외선체열진단검사는 복부비만을 간편하게 진단 할 수 있는 방법이고, 임상적으로 유용할 것으로 생각된다.
