Background: Compliance with colonoscopy among elderly individuals participating in colorectal cancer (CRC) screening programs is unsatisfactory, despite a high detection rate of bowel‐related diseases. In this study, our aim was to analyze the impact of risk factors on the trends of compliance and detection rates in colonoscopy among high‐risk individuals aged 60–74. Methods: A retrospective study was conducted on the high‐risk individuals aged 60–74 participating in the 2021 CRC screening program in Tianjin, China. Logistic regression analyses, including both univariate and multivariate analyses, were performed to explore the impact of different risk factors on colonoscopy compliance among the high‐risk individuals. Besides, the study investigated the influence of various risk factors on the detection rates of bowel‐related diseases among the high‐risk individuals who underwent colonoscopy. Results: A total of 24,064 high‐risk individuals were included, and 5478 individuals received a free colonoscopy, with an overall compliance of 22.76%. Among them, the adenoma detection rate was 55.46%. Males and individuals with a positive FIT had high compliance and detection rates for CRC, advanced adenomas (AA), advanced colorectal neoplasia (ACN), and colorectal neoplasm (CN). Individuals aged 70–74 were associated with low compliance but high CRC, ACN, and CN detection rates. Individuals who reported a history of chronic constipation, bloody mucous, and CRC in first‐degree relative showed high compliance but no significantwere associated with the detection rates of CRC, AA, and CN. Conclusion: This study reported several risk factors associated with the screening behaviors for CRC. Patterns and trends in CRC, AA, ACN, and CN compliance and detection rates correlate with risk factors. [ABSTRACT FROM AUTHOR]

Background To investigate occasional hypertension in preschool children aged 5–6 years, and to analyze its association with overweight or obesity to provide the basis for early prevention. Methods Cluster random sampling was used to select 63 out of 1,802 kindergartens in 16 districts of Tianjin from 2016 to 2018. Blood pressure, height, and weight were measured among 21,393 children aged 5–6 years. A retrospective questionnaire survey was conducted to collect environmental factors. A multivariate logistic regression model was used to analyze the association between overweight or obesity and occasional hypertension, after adjustment for environmental factors. Results The prevalence of high blood pressure in preschool children of Tianjin was 11.9%, and the rate of occasional hypertension was 17.5%. The detection rate of abnormal blood pressure in overweight and obese children was significantly higher than that in normal weight children (P < 0.01). After adjusted for environmental factors, overweight and obesity were positively associated with high blood pressure and occasional hypertension. The odds ratio (95% confidence interval) of overweight for high blood pressure and occasional hypertension was 1.61 (1.41–1.83) and 1.79 (1.61–1.99), respectively; and odds ratio (95% confidence interval) of obesity for high blood pressure and occasional hypertension was 2.15 (1.85–2.50) and 3.16 (2.82–3.53), respectively. Conclusions Overweight and obesity increase the risk of occasional hypertension in preschoolers. [ABSTRACT FROM AUTHOR]
