The performance of the Rose angina questionnaire in South Asian and European origin populations: a comparative study in Newcastle, UK.
BACKGROUND
The Rose angina questionnaire has been extensively used in different cultural settings, but may not perform consistently in different ethnic groups. We set out to assess the performance of the Rose angina questionnaire in UK South Asians compared with Europeans.


METHODS
Data on major ECG abnormalities, possible or definite Rose questionnaire angina and diagnosed angina were collected from an age- and sex-stratified random sample of 1509 adults from European, Indian, Pakistani and Bangladeshi ethnic groups.


RESULTS
The ECG abnormalities were commoner in South Asians than Europeans (6% versus 2% in men). The prevalence in both South Asian and European men of possible Rose angina and diagnosed angina was 18% and 8%, respectively, but definite Rose angina was less common in South Asians (3% versus 6%). Definite Rose angina showed lower sensitivity for other measures in South Asians than in Europeans: sensitivity for a doctor's diagnosis was 21% in South Asian and 37% in European men. For possible Rose angina, the corresponding figures were 81% and 84%. Similar patterns were seen in women.


CONCLUSIONS
The performance of the Rose angina questionnaire was sufficiently inconsistent to warrant further work to achieve greater cross-cultural validity. Possible Rose angina performed more consistently across ethnic groups than definite Rose angina and pending further validation studies may be the most appropriate form to use.
