Objective: To investigate the association between overweight, obesity, central obesity and hypertension, so as to provide the basis for formulating targeted hypertension prevention and control strategies. Methods: Permanent residents aged ≥18 years were selected in Wenzhou City, Zhejiang Province from June 2023 to August 2024 by a multistage cluster random sampling method. Data on demographic information, lifestyle, height, weight, waist circumference (WC), blood pressure, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. The prevalence of hypertension was calculated and standardized using the data of the Sixth National Population Census in 2010. Body mass index (BMI) was calculated to determine overweight and obesity, while WC was used to identify central obesity. The association between overweight, obesity, central obesity and hypertension were analyzed using multivariable logistic regression models. Results: A total of 38 593 residents were surveyed, including 19 481 (50.48%) males and 19 112 (49.52%) females. The median age was 46.00 (interquartile range, 26.00) years. The rates of overweight, obesity, and central obesity were 32.74% (12 634 individuals), 10.27% (3 963 individuals), and 27.87% (10 755 individuals), respectively. There were 11 813 cases of hypertension, with a prevalence and standardized prevalence of 30.61% and 24.41%, respectively. Multivariable logistic regression analysis showed that after adjusting for demographic information, lifestyle, diabetes and dyslipidemia, the likelihood of hypertension in the overweight and obesity groups was 1.927 (95%CI: 1.815-2.045) times and 3.724 (95%CI: 3.404-4.073) times that of the normal BMI group, respectively. The likelihood of hypertension in the central obesity group was 2.346 (95%CI: 2.214-2.486) times that of the normal WC group. The likelihood of hypertension in the central obesity only, overweight only, overweight with central obesity, obesity only and obesity with central obesity groups was 1.586 (95%CI: 1.391-1.809), 1.704 (95%CI: 1.582-1.835), 2.433 (95%CI: 2.254-2.626), 1.768 (95%CI: 1.424-2.194), and 4.466 (95%CI: 4.053-4.921) times that of the normal BMI and WC group, respectively. Conclusions Overweight, obesity and central obesity were all associated with hypertension among adult residents. The highest likelihood of hypertension was observed among adult residents with both general obesity and central obesity.

Objective To investigate the value of peripheral blood circRNA9226 combined with tumor markers for the diagnosis of lung adenocarcinoma.Methods A total of 30 patients with lung adenocarcinoma who were admitted to the Affiliated Lihuili Hospital of Ningbo University from December 2022 to January 2023 were selected as case group.Additionally,twenty healthy individuals who underwent physical examinations during the same period were selected as control group.The expression levels of circRNA9226,carcinoembryonic antigen(CEA),carbohydrate antigen(CA)199,and albumin(Alb)were compared between two groups.The diagnostic efficacy of circRNA9226 and CEA for lung adenocarcinoma was evaluated by receiver operating characteristic(ROC)curve,and the correlation between circRNA9226 and other indicators was analyzed.Results The peripheral blood circRNA9226 expression levels in case group was higher than that in control group(P＜0.05).The sensitivity of circRNA9226 and CEA for diagnosing lung adenocarcinoma was 83.3％and 46.7％,respectively,with specificity of 90.0％and 100.0％.Area under the curve(AUC)was 0.897 and 0.776,respectively.When both tests were combined,the sensitivity was 93.3％,accuracy was 92.0％,and AUC was 0.918,showing a significant improvement in both sensitivity and accuracy compared to single tests.The correlation analysis results showed that circRNA9226 was positively correlated with CEA concentration(r=0.371,P＜0.05)and negatively correlated with Alb concentration(r=-0.548,P＜0.05).Conclusion Peripheral blood circRNA9226 has advantages in distinguishing lung adenocarcinoma from healthy controls,and combined with CEA can further improve the diagnostic efficacy.
