Demographic determinants of risk, colon distribution and density scores of diverticular disease.

Aim: To investigate associations between ethnicity, age and sex and the risk, colon distribution and density scores of diverticular disease (DD).

Methods: Barium enemas were examined in 1000 patients: 410 male, 590 female; 760 whites, 62 Asians, 44 black africans (BAs), and 134 other blacks (OBs). Risks and diverticula density of left-sided DD (LSDD) and right-sided-component DD (RSCDD = right-sided DD + right and left DD + Pan-DD) were compared using logistic regression.
