Introduction: Diverticular disease (DD) is said to be uncommon in Africans and in Asians. Aim: To determine if patients of Indian subcontinent racial origin (ISC Asians) have a lower prevalence of DD compared to other patients (non-Asians). Method: All colonoscopies performed at St George's Hospital from October 1999 to October 2002 were studied. ISC Asians were identified by name. Results: 3013 patients were included. There were 245 ISC Asians and 2768 non-Asians. ISC Asians were younger and more likely to be male (mean age 55.1 years, M:F = 1:0.7) compared to non-Asians (mean age 60.1 years, M:F = 1:1.2). ISC Asians and non-Asians with DD had similar sex ratios (1:1.2 and 1:1.1, respectively). Indications for colonoscopy were similar in the two groups. Conclusions: There is a lower prevalence of DD among ISC Asians presenting for colonoscopy, compared to non-Asians. This cannot be explained by sex or age differences. If confirmed, our findings may provide opportunities For research into the pathogenesis of DD.
