Objective This study aims to investigate the characteristics of colorectal polyps in different age populations,providing a clinical foundation for early screening of intestinal tumors.Methods We conducted a retrospective analysis of clinical data from 571 patients with colorectal polyps at the First Hospital of Hebei Medical University,covering the pe-riod from April 2022 to March 2023.These patients were divided into three groups based on age:young group(75 pa-tients,≤44 years old),middle-aged group(256 patients,45-59 years old),and elderly group(240 patients,≥60 years old).The biological characteristics of colorectal polyps in each group were analyzed using the Chi-squared test.Results Male patients were more common in the young and middle-aged groups,whereas female patients were more prevalent in the elderly group(P＜0.001).Comparing the three groups,the incidence of polyps in the ascending colon was highest in elderly group(P=0.002),and the incidence of rectal polyps was highest in young group(P=0.001).Notably,the elderly group exhibited a significantly higher incidence of neoplastic rectal polyps compared to the middle-aged and young group[64.7％(139/215)vs.34.9％(60/172)vs.21.2％(14/66),P＜0.001].Additionally,the incidence of multiple polyps,polyps with a size ≥ 1.0 cm,and tubular adenomas were highest in elderly group(P＜0.05),while there was no significant difference in the lengths among different pathological types of polyps(P＞0.05).The incidence of tubular adenomas in polyps with ≤0.5 cm and 0.6-0.9 cm were highest in elderly group(P＜0.001),while the incidence of hyperplastic polyps was lowest in elderly group(P＜0.001).However,there was no significant difference in the pathological types of polyps with a size ≥1.0 cm among the three groups,with tubular adenomas being the most common for this size polyps(P＞0.05).Conclusion The biological characteristics of colorectal polyps exhibit variations across different age groups,including changes in the risk population,growth position,size,number,and path-ological types,which tend to follow a discernible trend with increasing age.
