Body Mass Index and Quality of Life in Patients Waiting for Coronary Angiography: A Pilot Study

Aim: There is evidence that the body mass index (BMI) is related, to some extent, to the quality of life (QoL) in different populations. The purpose of our study was to investigate the differences in QoL in relation to the BMI in patients awaiting coronary angiography. Method: The sample consisted of 100 patients (68 males and 32 females) with symptoms indicating coronary angiography. For all of them BMI was calculated. The participants completed the Duke Health profile questionnaire (DUKE) which measures adult self-reported functional health status. Results: After splitting the group in two according to the BMI median cut-off point, the findings reveal differences in the following aspects of QoL secondary to BMI: mental health (p = .006), general health (p = .038), perceived health (p = .008), anxiety (p = .022), depression (p = .008), anxiety-depression (p = .004), but not related to: physical health (p = .384), social health (p = .267), self-esteem (p = .172), pain (p = .797), disability (p = .710). Conclusion: Considering the findings, health counselling directed at regulating body weight is recommended as part of the positive health behaviour. It can benefit and improve some domains of the QoL of individuals having health problems. peerReviewed publishedVersion

研究目的：现有证据表明，身体质量指数（Body Mass Index, BMI）在不同人群中与生活质量（Quality of Life, QoL）存在一定程度的关联。本研究旨在探讨待接受冠状动脉造影患者的生活质量与BMI的相关性差异。
研究方法：本研究纳入100例存在冠状动脉造影指征的患者，其中男性68例、女性32例。为所有受试者测算BMI值；受试者同时完成杜克健康概况问卷（Duke Health Profile Questionnaire, DUKE），该问卷用于评估成人自我报告的功能健康状态。
研究结果：以BMI中位数为分界点将受试者分为两组后，结果显示BMI与下述生活质量维度存在显著关联：心理健康（p=0.006）、总体健康（p=0.038）、感知健康（p=0.008）、焦虑（p=0.022）、抑郁（p=0.008）以及焦虑-抑郁共病维度（p=0.004）；而与以下生活质量维度无显著关联：身体健康（p=0.384）、社会健康（p=0.267）、自尊（p=0.172）、疼痛（p=0.797）、功能障碍（p=0.710）。
研究结论：基于上述研究结果，建议将体重调控相关健康指导作为积极健康行为的组成部分，该措施可使存在健康问题的人群获益并改善其部分生活质量维度。
