Background Chronic kidney disease (CKD) is a serious risk to the health and longevity of the elderly, and hypertension is closely related to CKD. However, the studies on the correlation of blood pressure levels with the development and progression of CKD in older adults have shown inconsistent results. Objective To explore the association between blood pressure levels and the risk of CKD among the elderly in longevity areas of China. Methods From October 2021 to May 2022, a total of 989 older adults who underwent physical examination with biomedical indicators collected in 2012 were selected as subjects based on the subcohort of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) -Healthy Aging and Biomarkers Cohort Study (HABCS) . Age, gender, height, weight, blood pressure, blood lipid, blood glucose, routine blood and urine indicators were collected at baseline, and follow-up monitoring was conducted in 2014. Cox proportional hazards regression model was used to analyze the association between the blood pressure levels and the risk of CKD. Results A total of 989 subjects were included in the study, with a median age of 79 (70, 88) years. The cumulative follow-up were 2 046 person-years, with an average follow-up time of (2.07±0.50) years. There were 183 new cases of CKD, the cumulative incidence of CKD was 18.5%〔95%CI (16.1%, 21.1%) 〕, and the incidence density was 89.4/1 000 person-years. During the follow-up, 9.8% (10/102) , 14.0% (47/335) and 22.8% (126/552) of the older adults in the normal blood pressure, high normal blood pressure and hypertension groups developed CKD, respectively, and the difference was statistically significant among the three groups (χ2=16.40, P

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 (
