Overweight and obesity have become increasingly common among end-stage renal disease patients on hemodialysis. Yet, little attention has been given to what hemodialysis patients themselves think of their weight, how they perceive it affects their health, and their attitudes about or desire for weight reduction. We explored these issues using a survey that we designed specifically for the dialysis population.
Sixty-six chronic hemodialysis patients from a US urban center with a body mass index ≥25 kg/m and stable weight were recruited to participate in a cross-sectional study. The 12-question weight-related survey was validated by retesting a random portion of the study population.
Based on test-retest results, the survey had good to excellent validity. Seventy-nine percent of patients were black, 49% were male, 29% were overweight, and 71% were obese. In general, the patients underestimated their weight excess though 73% were interested in weight loss, of whom nearly half reported attempting to do so mostly through diet and exercise. The majority of participants interested in losing weight felt that doing so would improve their physical and emotional health. The most common barrier to weight reduction was a belief that it was too difficult (55%), followed by a lack of motivation, money, time, resources, and knowledge. Diet was the most common weight loss strategy (85%) considered, whereas bariatric surgery was the least common (6.1%).
A majority of overweight and obese hemodialysis patients believe their excess weight is adversely impacting their health and quality of life and therefore wish to lose weight.
超重和肥胖在接受血液透析的终末期肾病患者中越来越常见。然而,人们对血液透析患者自身对体重的看法、体重对健康的影响、以及他们对减肥的态度或愿望关注甚少。我们使用专门为透析人群设计的调查来探讨这些问题。
从美国一个城市中心的 66 名身体质量指数(BMI)≥25kg/m²且体重稳定的慢性血液透析患者中招募他们参与横断面研究。该 12 个问题的体重相关调查通过对研究人群的随机部分进行复测进行了验证。
基于复测结果,该调查具有良好到极好的有效性。79%的患者为黑人,49%为男性,29%超重,71%肥胖。总的来说,尽管 73%的患者对减肥感兴趣,但患者低估了自己的体重超标,其中近一半人报告主要通过饮食和运动来减肥。大多数有减肥意愿的参与者认为这样做会改善他们的身心健康。减肥的最大障碍是认为减肥太难(55%),其次是缺乏动力、金钱、时间、资源和知识。饮食是最常见的减肥策略(85%),而减重手术是最不常见的(6.1%)。
大多数超重和肥胖的血液透析患者认为他们的多余体重对他们的健康和生活质量有不利影响,因此希望减肥。
