Abstract

Malnutrition is a serious complication in patients on long-term CAPD treatment. Accordingly, quantitative evaluation of nutritional status is a critical issue. This study aimed to assess nutritional status by dual photon energy x-ray absorptiometry (DEXA) in CAPD patients. Total lean body mass (D-TBM), right arm lean mass (D-RAM) and body fat percent (D-% FAT) measured by DEXA were compared with mid-arm muscle circumference (MAMC) and body fat percent (AP-% FAT) measured by anthropometrics (AP) in 51 CAPD patients. The subjects were stratified into groups by gender, age, duration on CAPD, and diabetes mellitus or non-diabetes. There was significant correlation between D-TBM, D-RAM and MAMC (r = 0.519, p = 0.001, r = 0.545, p = 0.001) or D-% FAT and AP-% FAT (r = 0.763, p = 0.0001). However, in the groups of females with over 50 years and over 48 months of dialysis duration, there was no correlation between D-TBM, D-RAM and MAMC. The DEXA method is useful in the quantitative evaluation of nutritional status of dialysis patients serially.

摘要

营养不良是长期持续性非卧床腹膜透析（CAPD）治疗患者的一种严重并发症。因此，营养状况的定量评估是一个关键问题。本研究旨在通过双能X线吸收法（DEXA）评估CAPD患者的营养状况。对51例CAPD患者采用DEXA测量的总去脂体重（D-TBM）、右臂去脂体重（D-RAM）和体脂百分比（D-%FAT），与采用人体测量学（AP）测量的上臂中部肌肉周长（MAMC）和体脂百分比（AP-%FAT）进行比较。根据性别、年龄、CAPD治疗时间以及是否患有糖尿病，将研究对象进行分层分组。D-TBM、D-RAM与MAMC之间（r = 0.519，p = 0.001，r = 0.545，p = 0.001），或D-%FAT与AP-%FAT之间（r = 0.763，p = 0.0001）存在显著相关性。然而，在年龄超过50岁且透析时间超过48个月的女性组中，D-TBM、D-RAM与MAMC之间不存在相关性。DEXA方法有助于连续定量评估透析患者的营养状况。
