title: Patterns of tuberculosis in Indian and Pakistani/Bangladeshi patients: effects of age, date of first entry and ethnic group.
abstract: The pattern of tuberculosis in Indian, Pakistani and Bangladeshi patients in Blackburn (1978-1987) was compared with that for England and Wales (MRC Survey), with particular reference to the proportion with parenchymal lung disease, by a generalized linear model allowing for age, ethnic group and time since first entry. In Blackburn, the proportion with lung disease was higher in Pakistani/Bangladeshi (46%) compared with 28% in Indians, although in both groups this increased with age. In the MRC Survey, the proportions with lung disease were similar (Pakistani/Bangladeshi 36.5%, Indians 34%) but there was an increase in lung disease with age and year since first entry in the Indian ethnic group only. The reasons for the differences, and their implications are discussed.
