Association between Chronic Disease Risk Score and Cancer Risk: a Cohort Study

Background As with other chronic diseases, cancer presents a multidimensional state. And many chronic diseases share common risk factors with cancers. The association between a single chronic disease indicator and the risk of cancer is weak, so it is significant to construct a risk score composed of multiple chronic disease indicators and analyze its association with the risk of cancer. Objective To investigate the association between chronic disease risk score and cancer risk. Methods This study selected a total of 18 009 eligible individuals who had participated in Tianjin Chronic Disease Risk and Health Management Cohort Study and undergone physical examination in Health Management Center, Tianjin Medical University General Hospital from January 2015 to December 2019. All subjects completed the health risk assessment questionnaire, physical examination, and laboratory examination. Follow-up ended on the day of cancer occurrence or the day of follow-up termination (December 31, 2019) . Multivariate Cox regression model was used to evaluate the relationship of the risk of cancer (used as the dependent variable) with each of the chronic disease related indicators〔consisting of BMI, waist circumference, blood pressure, blood glucose, total cholesterol, triglyceride, uric acid, total bilirubin, heart rate, and estimated glomerular filtration rate (used as independent variables) 〕. And then the comprehensive score of chronic disease risk was calculated, and the cancer risk in tertile groups of the score 〔low-score group (
