Kim, Baik, Kim, Oh, and Lee: Prevalence and Risk Factors of Colorectal Adenoma in 14,932 Koreans Undergoing Screening Colonoscopy

Abstract

Background/Aims

Current international guidelines recommend colorectal cancer screening for average-risk people over 50 years of age. Accordingly, we aimed to estimate the prevalence of colorectal neoplasms in all age groups and evaluate associated risk factors.

Methods

Data of 14,932 subjects who underwent colonoscopy from July 2006 to January 2012 at Health Promotion Center, Gangnam Severance Hospital (Seoul, Korea) as part of a health check-up were reviewed retrospectively.

Results

The overall prevalence of colorectal neoplasms and adenoma were 34.6% and 25.3%, respectively. Colorectal adenoma was found in 3.2%, 13.0%, 21.7%, 33.8%, 44.0%, 50.5%, and 54.2% of subjects under 30 years, 30–39 years, 40–49 years, 50–59 years, 60–69 years, 70–79 years, and over 80 years of age (trend p<0.0001). Independent predictors of colorectal adenoma included male gender (OR 2.38, 95% CI 2.084–2.718), positive occult blood (2.266, 1.761–2.917), positive serology of Helicobacter pylori (1.253, 1.114–1.409) and hypertriglyceremia (1.267, 1.065–1.508). Compared to the 30–39 years of age reference group, the ORs for each age group were 0.195 (under 30 years), 1.634 (40–49 years), 2.954 (50–59 years), 5.159 (60–69 years), 5.640 (70–79 years), 11.020 (over 80 years), while the 95% CIs were 0.071–0.536 (under 30 years), 1.340–1.992 (40–49 years), 2.421–3.604 (50–59 years), 4.109–6.476 (60–69 years), 3.822–8.322 (70–79 years), and 2.809–42.234 (over 80 years).

Conclusions

Colorectal adenoma prevalence increased proportionally with age. Only subjects under the age of 30 years had a definitely lower prevalence of colorectal adenoma. Male gender, positive occult blood, positive serology of H. pylori, and hypertriglyceremia were associated risk factors of colorectal adenoma.
