“…Hindus and Sikhs seem be at much greater risk of UC than Europeans, while Muslims from the same ar eas (Gujarat and Punjab) have a similar risk to Europeans. However Bangladeshi Mus lims, who differ culturally from Gujarati Muslims, have the lowest risk of developing UC [23], The cultural and genetic differences between ethnic groups should receive our ur gent attention as they may reveal the aetiology of UC.…”

To assess the incidence of ulcerative colitis and proctitis in a defined migrant population, a retrospective, epidemiological community study was performed in the London Borough of Tower Hamlets from 1972 to 1989. The population of 164,000 includes 28,000 Bangladeshis. Potential cases were identified from hospital departments of pathology and medical records. There were 107 cases of ulcerative colitis in Europeans and 5 in Bangladeshis. There were 74 and 2 cases of proctitis in these communities, respectively. The mean standardised incidence of ulcerative colitis in Bangladeshis (1.8 cases/10⁵/year) was marginally lower than in Europeans (6.2 cases/10⁵/year, Z= 0.7, n.s.). The mean standardised incidence of proctitis in Bangladeshis was 0.6 cases/10⁵/year and in Europeans 3.2 cases/10⁵/year (Z = 0.6 n.s.). Anatomical extent of colitis was similar in all ethnic communities, although complications were less likely in minority groups. These findings suggest that the incidence of ulcerative colitis and proctitis in Bangladeshis, in Britain, is amongst the lowest in the world.

“…A recent retrospective study from Leicester on abdominal tuberculosis also demonstrated an increased risk in Hindu Asians (relative risk= 2-3). 7 The low response rate in our community controls was possibly because our original invitations were explicit about the role of the survey in investigating tuberculosis, a disorder which still carries a considerable stigma. Hindu cases were less likely to respond than Muslim cases, while Hindu controls were more likely than Muslims to agree to an interview (table 2).…”

Background -In a previous retrospective study of tuberculosis in south London among Asian immigrants from the Indian subcontinent Hindu Asians were found to have a significantly increased risk for tuberculosis compared with Muslims. This finding has been further investigated by examining the role of socioeconomic and lifestyle variables, including diet, as risk factors for tuberculosis in Asian immigrants from the Indian subcontinent resident in south London. Methods -Using a case-control study technique Asian immigrants from the Indian subcontinent diagnosed with tuberculosis during the past 10 years and two Asian control groups (community and outpatient clinic controls) from the Indian subcontinent were investigated. Cases and community controls were approached by letter. A structured questionnaire concerning a range of demographic, migration, socioeconomic, dietary, and health topics was administered by a single trained interviewer to subjects (56 cases and 100 controls) who agreed to participate. Results -The results confirmed earlier findings that Hindu Asians had an increased risk oftuberculosis compared with Muslims. However, further analysis revealed that religion had no independent influence after adjustment for vegetarianism (common among Hindu Asians). Unadjusted odds ratios for tuberculosis among vegetarians were 2-7 (95% CI 1-1 to 6.4) using community controls, and 4-3 (95% CI 1-8 to 10.4) using clinic controls. There was a trend of increasing risk of tuberculosis with decreasing frequency of meat or fish consumption. Lactovegetarians had an 85 fold risk (95% CI 1-6 to 45.4) compared with daily meat/ fish eaters. Adjustment for a range ofother socioeconomic, migration, and lifestyle variables made little difference to the relative risks derived using either community or clinic controls. Conclusions -These results indicate that a vegetarian diet is an independent risk factor for tuberculosis in immigrant Asians. The mechanism is unexplained. However, vitamin D deficiency, common among vegetarian Asians in south London, is known to affect immunological competence. Decreased immunocompetence associated with a vegetarian diet might result in increased mycobacterial reactivation among Asians from the Indian subcontinent.
