The menopausal age is one of the important menopausal factors, and women of different menopausal ages have different risks of diabetes. This study reviewed the evidence from prospective studies on the association between the age at natural menopause and diabetes risk, both domestically and internationally, and presented its research design and main findings. Advanced menopause, especially premature and early menopause, will increase the risk of diabetes in postmenopausal women. The research on the influence of delayed menopause on the incidence of diabetes is still insufficient. Many factors may modify the association between menopausal age and the risk of diabetes.

Objective: To analyze the disease burden of chronic obstructive pulmonary disease (COPD) and changes in its risk factors among residents in Zhejiang Province from 1990 to 2021, so as to identify key priorities for COPD prevention and control. Methods: Data on COPD mortality and disability-adjusted life years (DALY) for residents in Zhejiang Province from 1990 to 2021 were collected from the Global Burden of Disease (GBD) 2021 database. Standardized mortality and standardized DALY rate were calculated using the GBD 2021 world population standard structure. Premature mortality was computed via the life table method. The average annual percent change (AAPC) was applied to analyze trends in COPD mortality, DALY rate, and premature mortality. Changes in deaths of COPD risk factors were evaluated using population attributable fraction (PAF). Results: From 1990 to 2021, the standardized COPD mortality in Zhejiang Province decreased from 272.40/100 000 to 70.56/100 000 (AAPC=-4.395%), and the standardized DALY rate declined from 4 167.37/100 000 to 1 071.89/100 000 (AAPC=-4.396%). Similar downward trends were observed in both males (AAPC=-3.933%, -4.173%) and females (AAPC=-4.785%, -4.480%), all P<0.05. Crude mortality and DALY rates increased with age, and the crude mortality and DALY rates of various age groups in Zhejiang Province showed decreasing trends from 1990 to 2021 (all P<0.05). The premature mortality declined from 4.37% to 0.60% from 1990 to 2021 (AAPC=- 6.206%), with consistent trends across males and females (AAPC=- 6.144%, - 6.379%, all P<0.05). From 1990 to 2021, particulate matter pollution showed the largest reduction in PAF (- 56.76%), while ambient ozone pollution had the largest increase (103.07%) in Zhejiang Province. By 2021, smoking became the leading risk factor for deaths of COPD (PAF=43.32%). Conclusions The standardized mortality, standardized DALY rate, and premature mortality for COPD show consistent declining trends in Zhejiang Province from 1990 to 2021. However, risk factors such as smoking and ambient ozone pollution require intensified focus to further reduce disease burden of COPD.

Objective:To understand the epidemiological characteristics of metabolic syndrome(MetS) among adult residents in Zhejiang Province and compare three diagnostic criteria in adult residents.Methods:In this cross-sectisnal study participants were randomly chosen using multi-stage stratified cluster sampling method from 10 national chronic disease risk factor monitoring sites in Zhejiang Province of the 2018 China Chronic Disease and Risk Factors Surveillance Project. Demographics and information on chronic disease prevalence were obtained through questionnaire, physical measurements, and laboratory. After complex weighting of the data, an analysis and comparison of the prevalence of MetS under different diagnostic criteria among adult residents in Zhejiang Province was conducted.Results:A total of 5 369 adult residents were included, 2 411 males and 2 958 females. The prevalence of MetS using JIS, CDS and IDF diagnostic criteria was 33.62%, 25.32%, and 24.25%, respectively. The consistency rate between IDF and JIS was the highest(89.11%) and the Kappa value was 0.768( P<0.001). The consistency rate between IDF and CDS diagnostic criteria was 84.53%, and the Kappa value was 0.631( P<0.001). The consistency rate between JIS and CDS was the lowest(83.17%), and the Kappa value was 0.621( P<0.001). Under CDS diagnostic criteria, the prevalence of MetS was associated to gender, marital status, smoking and drinking. Conclusion:The prevalence of MetS is at a relatively high level among adult residents in Zhejiang province. The consistency between IDF and JIS diagnostic criteria is the highest. Screening for MetS should be strengthened to detect high-risk individuals early, reduce the risk of cardiovascular and cerebrovascular diseases and diabetes, and improve the quality of life of residents.

Objective:To explore the spatial autocorrelation and macro influencing factors of stroke mortality in Zhejiang Province in 2015-2020 and provide a scientific basis for stroke prevention and control strategy.Methods:The data on stroke death were obtained from Zhejiang Chronic Disease Surveillance System. The spatial distribution of stroke mortality was explored by mapping and spatial autocorrelation analysis. The spatial panel model analyzed the correlation between stroke mortality and socioeconomic and healthcare factors.Results:From 2015 to 2020, the average stroke mortality was 68.38/100 thousand. The standard mortality of stroke was high in the areas of east and low in the west, high in the south and low in the north. Moreover, positive spatial autocorrelation was observed (Moran's I=0.274-0.390, P<0.001). Standard mortality of stroke was negatively associated with per capita gross domestic product (GDP) ( β=-0.370, P<0.001), per capita health expenditure ( β=-0.116, P=0.021), number of beds per thousand population ( β=-0.161, P=0.030). Standard mortality of ischemic stroke was negatively associated with per capita GDP ( β=-0.310, P=0.002) and standard management rate of hypertension ( β=-0.462, P=0.011). Standard mortality of hemorrhagic stroke was negatively associated with per capita GDP ( β=-0.481, P<0.001), per capita health expenditure ( β=-0.184, P=0.001), number of beds per thousand population ( β=-0.288, P=0.001) and standard management rate of hypertension ( β=-0.336, P=0.029). Conclusions:A positive spatial correlation existed between stroke mortality in Zhejiang Province in 2015-2020. We must focus more on preventing and controlling strokes in relatively backward economic areas. Moreover, to reduce the mortality of stroke, increasing the investment of government medical and health funds, optimizing the allocation of medical resources, and improving the standard management rate of hypertension are important measures.

Objective: To investigate the degree and influencing factors of glycosylated hemoglobin ( HbA1c ) control among patients with type 2 diabetes ( T2DM ) living in rural communities of Zhejiang Province, so as to provide the reference for optimizing the management of diabetes patients in rural communities. Methods: Permanent adult patients with T2DM that were registered and received standardized management in all communities of Jiashan County and Suichang County, and 6 communities of Yongkang City, Zhejiang Province in 2016 were recruited, and their demographic characteristics were captured from the health record system and chronic disease management system. The height, body weight, waist circumstance and blood pressure were measured, and HbA1c and blood lipid parameters were detected. The degree of HbA1c control ( <7% ) was analyzed, and its influencing factors were identified using a multivariable logistic regression model. Results: A total of 10 339 patients with T2DM were enrolled, including 4 520 men ( 43.72% ) and 5 819 women ( 56.28% ), with a mean age of ( 63.54±9.78 ) years and the mean course of diabetes of ( 6.36±4.73 ) years. The rate of HbA1c control was 47.89%. Multivariable logistic regression analysis showed that males ( OR=1.123, 95%CI: 1.024-1.233 ), region ( Suichang, OR=2.413, 95%CI: 2.106-2.765; Yongkang, OR=2.460, 95%CI: 2.188-2.767 ), course of disease ( 5-9 years, OR=1.724, 95%CI: 1.504-1.977; 10 years and longer, OR=2.881, 95%CI: 2.477-3.351 ), use of hypoglycemic drugs ( OR=1.203, 95%CI: 1.089-1.329 ), development of chronic complications ( OR=1.190, 95%CI: 1.027-1.379 ), uncontrolled blood pressure ( OR=1.140, 95%CI: 1.030-1.261 ), uncontrolled blood lipid ( OR=1.258, 95%CI: 1.104-1.433 ), and smoking ( OR=1.318, 95%CI: 1.165-1.491 ) were statistically associated with HbA1c control among T2DM patients. Conclusion The rate of HbA1c control was 47.89% among T2DM patients in rural communities of Zhejiang Province. HbA1c control should be given a high priority among men living in low-economic-level regions with long course of disease, use of hypoglycemic drugs, chronic complications, smoking, uncontrolled blood pressure and lipid.

Objective: To investigation the correlation between sleep duration and hypertension among adults in Zhejiang Province, and to provide scientific evidence for the prevention and control of hypertension. Methods: Permanent residents at age of 18 years and older were enrolled from 10 surveillance sites for risk factors of chronic diseases included in the 2018 China Chronic Diseases and Risk Factors Surveillance Program. Subjects' demographic characteristics, smoking, alcohol consumption, sleep duration and development of hypertension were collected, and following complex weighting calculations, the association between sleep duration and hypertension were examined using a multivariable logistic regression model. Results: Totally 5 770 adults were included, including 2 952 men (50.72%) and 3 178 women (49.28%), and the prevalence of hypertension was 29.39% (2 702 cases). There were 712 (8.37%), 1 077 (18.77%), 1 582 (28.68%), 1 717 (34.60%) and 682 adults (9.57%) with sleep duration of <6 h/d, 6 to 7 h/d, 7 to 8 h/d, 8 to 9 h/d and 9 h/d and longer, respectively. Taking the sleep duration of 7 to 8 h/d as a reference, multivariable logistic regression analysis identified a significant association between sleep duration of <6 h/d and the risk of hypertension (OR=1.709, 95%CI: 1.184-2.466), a significant association between sleep duration of 9 h/d and longer and the risk of hypertension (OR=1.369, 95%CI: 1.006-1.862) in men, significant associations between sleep duration of <6 h/d (OR=2.174, 95%CI: 1.528-3.093) and 6 to 7 h/d (OR=1.412, 95%CI: 1.078-1.850) and the risk of hypertension in women, and significant associations between sleep duration of <6 h/d (OR=3.095, 95%CI: 1.025-9.347) and 6 to 7 h/d (OR=2.046, 95%CI: 1.156-3.622) and the risk of hypertension in residents at ages of 18 to 44 years. Conclusions Short sleep duration may increase the risk of hypertension among adults at ages of 18 to 44 years in Zhejiang Province. Short sleep duration may increase the risk of hypertension in women and long sleep duration may increase the risk of hypertension in men.

Objective: To estimate the burden of disease (BOD) attributable to main risk factors of chronic diseases in Zhejiang Province in 2017, so as to provide the evidence for formulating the control strategy for chronic diseases and reducing BOD. Methods: The results of the Global Burden of Disease Study 2017 ( GBD 2017 ) were extracted to evaluate years of life lost due to premature mortality ( YLL ), years lived with disability ( YLD ) and disability-adjusted life years ( DALY ). The gender- and age-specific BOD attributable to main risk factors of chronic diseases, including the environment, metabolism and behaviors, in Zhejiang Province in 2017 was estimated and compared with those in 1990. Results: High DALY rates of chronic diseases were estimated attributable to tobacco use ( 2 807.08/105 ), unreasonable diet ( 2 724.72/105 ) and hypertension ( 1 878.69/105 ) in Zhejiang Province in 2017, and high DALY rates of chronic diseases were estimated in men attributable to tobacco use ( 4 764.77/105 ), unreasonable diet ( 3 297.00/105 ) and hypertension ( 2 076.92/105 ), while high DALY rates of chronic diseases were estimated in women attributable to unreasonable diet ( 2 117.16/105 ), hypertension ( 1 668.24/105 ) and hyperglycemia ( 1 100.53/105 ), respectively. Among individuals at ages of 15 to 49 years, high DALY rates of chronic diseases were estimated attributable to unreasonable diet ( 759.29/105 ), drug abuse ( 611.71/105 ) and tobacco use ( 605.37/105 ); among individuals at ages of 50 to 69 years, high DALY rates of chronic diseases were estimated attributable to tobacco use ( 5 528.37/105 ), unreasonable diet ( 4 628.18/105 ) and hypertension ( 2 757.78/105 ); and among individuals at ages of 70 years and older, high DALY rates of chronic diseases were estimated attributable to unreasonable diet ( 16 370.09/105 ), tobacco use ( 15 551.40/105 ) and hypertension ( 14 408.63/105 ). As compared to those in 1990, the DALY rates of chronic diseases attributable to high body mass index, alcohol use, hyperglycemia, high low-density lipoprotein cholesterol and drug abuse increased by 108.23%, 48.59%, 23.17%, 17.64% and 6.06%, and the DALY rates of chronic diseases attributable to air pollution, occupational risks, unreasonable diet and impaired renal function reduced by 51.11%, 44.81%, 22.49% and 19.83%, and no significant alterations were detected in DALY rates of chronic diseases attributable to tobacco use or hypertension in 2017. Conclusions There was a high BOD of chronic diseases attributable to tobacco use, unreasonable diet and hypertension in Zhejiang Province in 2017, and the BOD of chronic diseases attributable to high body mass index, alcohol use and hyperglycemia appeared a tendency towards a rise in Zhejiang Province in 2017 relative to in 1990.

Objective : To explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province, so as to provide scientific evidence for the prevention and control of hypertension. Methods: Data were collected from 10 national surveillance sites in Zhejiang Province in the 2018 China Chronic Disease and Risk Factors Surveillance. The multivariate logistic regression model was used to explore the relationship between alcohol consumption and hypertension in adults of Zhejiang Province. Results : Among 5 908 people included, 2 641 were males, accounting for 50.38%; and 3 267 were females, accounting for 49.62%. There were 2 721 cases of hypertension ( 28.54% ). The number of the cases with no, light and excessive alcohol consumption was 3 945, 1 117 and 846, accounting for 66.28%, 23.65% and 10.07%, respectively, after complex sampling weighting. The results of the multivariate logistic regression model showed that compared with those with no alcohol consumption, the adults with excessive alcohol consumption had higher risk of hypertension ( OR=2.126, 95%CI: 1.649-2.741 ); men with light ( OR=1.875, 95%CI: 1.075-3.270 ) and excessive alcohol consumption ( OR=2.752, 95%CI: 2.021-3.748 ) had higher risk of hypertension; the 18-<45-year-old adults with light ( OR=2.441, 95%CI: 1.171-5.087 ) and excessive alcohol consumption ( OR=3.368, 95%CI: 1.609-7.049 ), and the ≥60-year-old adults with excessive alcohol consumption ( OR=1.632, 95%CI: 1.174-2.269 ) had higher risk of hypertension. Conclusions Light and excessive alcohol consumption are associated with hypertension in Zhejiang adults. The association is stronger between excessive alcohol consumption and hypertension than between light alcohol consumption and hypertension.

Objective:To evaluate the effect of comprehensive intervention combined with clinical preventive services and lifestyle adjustment on high-risk populations of cardiovascular disease.Methods:In 2015, 4 towns (streets) in Tongxiang City, of Zhejiang Province including Heshan Town, Longxiang Street, Wutong Street, and Fengming Street, were selected by using the typical sampling. The towns (streets) were allocated to the intervention group (Heshan Town and Longxiang Street) and the control group (Wutong Street and Fengming Street) by using the cluster random sampling. In each town (street), hypertension patients aged 50 to 74 years old who were taking community medicine management and with a 10-year cardiovascular disease risk ≥10% were recruited as subjects. There were 1 823 subjects in the intervention group and 1 883 in the control group. The intervention group was given a 1-year comprehensive intervention combining clinical preventive services and lifestyle adjustment, while the control group received routine chronic disease management. After the intervention, the final questionnaire investigation was conducted and health physical examination data were obtained. The death, acute coronary heart disease events and stroke incidence were the primary outcomes, and cardiovascular disease-related knowledge and behavior, clinical preventive services utilization, physical changes, blood fat index and 10-year cardiovascular disease risk were the secondary outcomes. The difference-in-difference model was used to evaluate the effects of interventions.Results:The age of subjects in the intervention and control group was (68.76±3.75) and (67.90±4.56) years old, respectively. After 1-year intervention, the incidence of mortality, acute coronary events and stroke in intervention group was 1.65% (30 cases), 0.27% (5 cases) and 2.69% (49 cases), respectively, which showed no statistical difference compared to the control group [1.33% (25 cases), 0.32% (6 cases) and 2.07% (39 cases)]. After adjusting for the age, gender, education, marital status, self-assessed family income level and situation of taking antihypertensive drugs, the difference-in-difference model showed that the body mass index and diastolic blood pressure in the intervention group decreased by 0.33 kg/m 2 and 1.49 mmHg (1 mmHg=0.133 kPa). Compared with the control group, daily vegetable consumption proportion, the awareness rates of aspirin, stains, salt intake, and oil intake increased by 4.76%, 26.22%, 29.56%, 10.80%, and 15.17%, respectively ( P<0.05). Conclusion:After the 1-year comprehensive intervention, there was no significant change in primary outcomes among high-risk populations of cardiovascular disease. In secondary outcomes, body mass index and diastolic blood pressure declined and cardiovascular disease-related knowledge awareness increased.
