Background There is an increasing burden of coronary heart disease in China due to its lifestyle changes and population aging. However, the epidemiology of angina (a portent of future myocardial infarction) has been not well studied. We examined the performance of the Rose angina questionnaires and determined prevalence of angina in older adults in the urban and rural communities of China. Methods A household-based, community survey was conducted in four provinces in China. We interviewed 4,299 men and women aged ≥ 60 years during 2008-2009. We identified angina from self-reported doctor diagnosis and from the Rose questionnaire. Results 282 participants had doctor-diagnosed angina and 246 had possible Rose angina. There was a fair agreement between the two diagnoses (kappa=0.38, p<0.001). It was consistent in urban (0.38) and rural (0.39) communities, but varied between men (0.35) and women (0.39). World age-standardized prevalence of angina (%) was 6.48 (95%CI 5.70-7.25) by doctor's diagnosis (5.05, 3.97-6.13 for men vs 7.57, 6.48-8.67 for women) and 5.72 (4.99-6.47) by Rose questionnaire's diagnosis (3.69, 2.76-4.63 for men vs 7.22 6.15-8.29 for women). The corresponding figures in all urban participants were 8.26 (6.98-9.55) and 5.46 (4.41-6.51), and in rural 4.57 (3.66-5.48) and 5.95 (4.91-6.99) respectively. Conclusions There may be a lower prevalence of angina in older adults in China than those in the West. The Rose questionnaire may underestimate the prevalence of angina in China.
