Objective: To investigate the trends in mortality and life loss due to falls among the elderly in Wenzhou City, Zhejiang Province, so as to provide the basis for formulating prevention and control measures for falls among the elderly. Methods: The data on fall-related deaths among the elderly aged 60 and above in Wenzhou City were collected through the Wenzhou Chronic Disease Monitoring and Management Information System from 2015 to 2023. The crude mortality was calculated and standardized using the data from the Sixth National Population Census in 2010. The life loss were measured using potential years of life lost (PYLL), average years of life lost (AYLL), and potential years of life lost rate (PYLLR). The trends in mortality and life loss among the elderly were analyzed using the annual percent change (APC) and average annual percent change (AAPC). Results: There were 11 378 deaths due to falls among the elderly in Wenzhou City from 2015 to 2023, with a crude mortality of 82.67/100 000 and a standardized mortality of 65.32/105, which appeared no significant changing trend (AAPC=3.401%、2.995%,both P>0.05). There was a tendency towards a rise from 2019 to 2023 (APC=12.592%、11.507%, both P<0.05). The majority of falls occurred at home, with 6 312 cases accounting for 55.48%. The primary types of fall-related deaths were slips, trips, and falls on the same level, with 8 541 cases representing 75.07%. The crude mortality and standardized mortality of falls in males were 76.63/105 and 60.86/105, which were lower than that in females at 88.72/100 000 and 70.33/100 000 (both P<0.05), and the trends were consistent with the overall population. The crude mortality of falls among the elderly increased with age (P<0.05). From 2015 to 2023, the crude mortality of falls among the elderly aged 60 to <65 years showed an upward trend (AAPC=4.860%, P<0.05), while no significant trend was observed in other age groups (all P>0.05). The PYLL was 5 123 person-years, the AYLL was 0.45 years per person, and the PYLLR was 0.37‰. From 2015 to 2023, PYLL showed an upward trend (AAPC=5.477%, P<0.05). The PYLL, AYLL, and PYLLR for males were 3.08 times, 3.48 times, and 2.67 times those of females, respectively. Conclusions From 2015 to 2023, the mortality of falls among the elderly in Wenzhou City had remained relatively stable. However, PYLL showed an upward trend. Males and older seniors were key groups for falls prevention. It is recommended to enhance health education and promote age-friendly home modifications to prevent falls among the elderly.

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.

Anticipatory anxiety is a negative emotion that arises when individuals encounter potential threats or uncertainties in the future. It is the core symptom of a variety of anxiety disorders, and is closely associated with the occurrence, severity, treatment outcome, and prognosis of anxiety disorders, which has garnered a growing amount of focus in clinical practice. Nevertheless, scientific research on anticipatory anxiety continues to face obstacles such as unclear pathological mechanisms, the absence of simple and consistent self-assessment tools, and effective interventions. To improve understanding of the role of anticipatory anxiety in the diagnosis and treatment of anxiety disorders, this study reviews pertinent domestic and international literature, and briefly introduces the concept, assessment and measurement, activation paradigm, pathological mechanisms, and interventions of anticipatory anxiety.
