Measurement of biological age may help to assess the risk of colorectal adenoma in screening colonoscopy

Figure 1 Prevalence of colorectal adenoma according to chronological age and biological age. When the subjects were divided into four groups (≤39 yr; 40-49 yr; 50-59 yr; ≥ 60 yr), the prevalence of colorectal adenoma increased with increasing biological age (P < 0.001).

Figure 2 The prevalence of colorectal adenoma according to metabolic syndrome and age gap. The incidence of colorectal adenoma increased for the first group (MS- and BA < CA), the second group (MS- and BA ≥ CA), the third group (MS+ and BA ≥ CA), and the fourth group (MS+ and BA < CA) (P < 0.05). MS: Metabolic syndrome; BA: Biological age; CA: Chronological age.
