Abstract

BACKGROUND: To assess the association of sedentary time and physical activity with the occurrence of colorectal adenomas in asymptomatic participants. METHODS: We conducted a case-control study at Taipei Veterans General Hospital, Taiwan, to examine sedentary time, physical activity, and their joint effects on colorectal adenoma risk among asymptomatic participants. Conditional logistic regression analysis was used to estimate odds ratios (ORs) and 95% CIs. RESULTS: Among 5982 asymptomatic adults undergoing health screening, shorter sedentary time was independently associated with a lower risk of colorectal adenoma (n = 3616), after adjusting for other risk factors, including physical activity. The ORs (95% CIs) for each category of sedentary time >450, 300 to 450, and
