Psychological distress is an undifferentiated combination of symptoms that may be related to the occurrence of angina pectoris (AP). However, few studies have investigated the relationship between psychological distress and AP, particularly in Asian populations. The purpose of this study was to examine the relationship between psychological distress and AP in Taiwanese adults.
We adopted a cross-sectional design to explore the data of the 2005-2008 Nutrition and Health Survey in Taiwan. In total, 2080 subjects (aged ≥ 19 years) responded to questionnaire interviews and underwent physical examinations. Each of the five dimensions of psychological distress (sleep disturbance, anxiety, hostility, depression, and feelings of inferiority) were scored (from 0-20) according to the Five-Item Brief Symptom Rating Scale (BSRS-5). A score ≥ 6 points indicated psychological distress. AP was evaluated using a modified Rose questionnaire.
In total, 102 subjects (3.6%) had AP, and 231 subjects (8.8%) had symptoms of psychological distress. After adjusting for the basic data, metabolism, and lifestyle covariates, the BSRS-5 total score was associated with AP (odds ratio [OR] = 1.2, 95% confidence interval [CI] = 1.13-1.26, p < 0.001). Subjects with psychological distress had a higher risk of AP (OR = 2.97, 95% CI = 1.76-4.99, p < 0.001).
The presence of AP is associated with psychological distress. Health care providers should therefore be aware of the impact of psychological distress on AP. Our study findings can serve as a reference for AP assessments. Large scale longitudinal studies are needed to confirm a causal relationship between psychological distress and AP.
心理困扰是一组可能与心绞痛（AP）发生有关的未分化症状。然而，很少有研究调查心理困扰与 AP 之间的关系，特别是在亚洲人群中。本研究旨在探讨台湾成年人心理困扰与 AP 之间的关系。
我们采用横断面设计，探讨了台湾 2005-2008 年营养与健康调查的数据。共有 2080 名年龄≥19 岁的受试者接受了问卷调查和体检。根据五分量表简明症状评定量表（BSRS-5），对心理困扰的五个维度（睡眠障碍、焦虑、敌意、抑郁和自卑感）进行评分（0-20 分）。得分≥6 分表示心理困扰。AP 采用改良的 Rose 问卷进行评估。
共有 102 名受试者（3.6%）患有 AP，231 名受试者（8.8%）出现心理困扰症状。调整基本数据、代谢和生活方式协变量后，BSRS-5 总分与 AP 相关（比值比[OR] = 1.2，95%置信区间[CI] = 1.13-1.26，p < 0.001）。有心理困扰的受试者发生 AP 的风险更高（OR = 2.97，95% CI = 1.76-4.99，p < 0.001）。
AP 的存在与心理困扰有关。因此，医疗保健提供者应意识到心理困扰对 AP 的影响。我们的研究结果可以为 AP 评估提供参考。需要进行大规模的纵向研究来确认心理困扰与 AP 之间的因果关系。
