title: Prevalence of colonic diverticulosis in mainland China from 2004 to 2014.
abstract: The aim of this study was to determine the prevalence of colonic diverticulosis in mainland China. Sixty two thousand and thirty-four colonoscopies performed between Jan 2004 and Dec 2014 were reviewed retrospectively. The overall diverticulosis prevalence was 1.97% and out of this, 85.3% was right-sided. Prevalence does not change, significantly, on trends between the period 2004-2014. The peak of prevalence of diverticulosis was compared between the female group aged >70 years to the male one of 41-50 years. The other peak, otherwise, was compared between the group of 51-60 years with the right-sided diverticulosis to the one of >70 years with left-sided disease. Multivariate analysis suggested that the male gender could be a risk factor for diverticulosis in the group aged ≤70 years, but not for the older patients. In addition, among men was registered an increased risk factor for right-sided diverticulosis and, at the same time, a protective one for left-sided localization. In conclusion, the prevalence of colonic diverticulosis is very low in mainland China and it does not change significantly on trends over the time. Both the prevalence of this condition and its distribution changes according to the age and the genders. These findings may lead the researchers to investigate the mechanisms causing this kind of disease and its distribution in regard of the age and the gender.
