Objective:
To investigate the mortality and years of life lost due to drowning in Huzhou City from 2012 to 2021, so as to provide insights into drowning prevention and control.
Methods:
The mortality surveillance data on drowning in Huzhou City from 2012 to 2021 were collected from the Zhejiang Chronic Disease Surveillance Information Management System. The crude mortality and standardized mortality of drowning by the 2010 population census data in 2010, years of potential life lost (YPLL) and working years of potential life lost (WYPLL) due to drowning were calculated. In addition, the annual percent change (APC) was used to analyze the trends in drowning mortality and the rate of YPLL and WYPLL in Huzhou City from 2012 to 2021.
Results:
A total of 1 681 deaths occurred due to drowning in Huzhou City from 2012 to 2021, accounting for 9.11% of total injury deaths. The overall mortality and standardized mortality of drowning were 6.35/105 and 4.70/105, respectively, and mortality and standardized mortality of drowning were 6.95/105 and 5.44/105 in men and 5.76/105 and 3.98/105 in women, respectively. The highest mortality of drowning was found in residents at ages of 65 years and older (16.04/105 to 27.02/105), followed by in residents at ages of less than 5 years (2.54/105 to 16.37/105). The overall mortality of drowning was 5.29/105 to 7.21/105 among residents in Huzhou City from 2012 to 2021, and no significant change tendency was seen (APC=-2.18%, t=-2.085, P=0.071). The standardized mortality of drowning reduced from 6.10/105 to 3.69/105 (APC=-4.88%, t=-4.215, P=0.003). In addition, the YPLL and rate of YPLL, and WYPLL and the rate of WYPLL due to drowning mortality were 22 620.50 person-years, 0.10%, 17 956.50 person-years and 0.08% in Huzhou City from 2012 to 2021, respectively, and the rates of YPLL (APC=-6.95%, t=-3.203, P=0.016) and WYPLL (APC=-7.60%, t=-3.126, P=0.014) both appeared a tendency towards a decline from 2012 to 2021.
Conclusions
The standardized mortality of drowning and rate of YPLL appeared a tendency towards a decline among residents living in Huzhou City from 2012 to 2021, and residents at ages of 65 years and older and less than 5 years are high-risk populations for management of drowning mortality.

Objective:
To investigate the prevalence and influencing factors of comorbidity of chronic diseases among hypertensive patients with uncontrolled blood pressure in Huzhou City, so as to provide insights into community hypertension control.
Methods:
Hypertensive patients with uncontrolled blood pressure at ages of 35 to 74 years were sampled using a cluster random sampling method from 5 districts (counties) of Huzhou City. Participants' demographics, living behaviors, and development of chronic diseases were collected using questionnaires, and the height, body weight, waist circumference and blood pressure were measured. Blood glucose, blood lipid and other biochemical parameters were detected, and the number and combination of comorbidity of chronic diseases were descriptively analyzed. Factors affecting the comorbidity of chronic diseases were identified using a multivariable ordinal logistic regression model.
Results:
A total of 1 215 respondents were included, with a mean age of (60.83±7.76) years, and including 652 men (53.66%) and 563 women (46.34%). The prevalence of dyslipidemia, diabetes, hyperuricemia and cardiac encephalopathy was 45.10%, 30.95%, 23.05% and 5.10%, respectively. The prevalence of comorbidity of chronic diseases was 69.22% among respondents, and there were 497 respondents with one comorbidity (40.91%), 272 with two comorbidities (22.39%) and 72 with three and more comorbidities (5.93%). Hypertension+dyslipidemia (20.74%), hypertension+diabetes+dyslipidemia (9.96%) and hypertension+diabetes+dyslipidemia+hyperuricemia (4.36%) were predominant comorbid combinations. Multivariable ordinal logistic regression analysis showed that participants with overweight (OR=1.782, 95%CI: 1.390-2.286), obesity (OR=2.411, 95%CI: 1.802-3.222), grade 2 hypertension (OR=1.438, 95%CI: 1.077-1.919) had a higher risk of multiple comorbidities than those with normal body mass index and controlled blood pressure, and women (OR=0.563, 95%CI: 0.456-0.696) had a lower risk of multiple comorbidities than men.
Conclusions
The prevalence of comorbidity of chronic diseases was 69.22% among community hypertensive patients with uncontrolled blood pressure in Huzhou City, and the comorbidity of chronic diseases mainly included dyslipidemia and diabetes. Men, overweight, obesity and hypertension resulted in a high risk of comorbidity of chronic diseases.

Objective:
To investigate the current situation and influencing factors of knowledge, attitude and practice (KAP) of fall prevention among the elderly in Huzhou City, Zhejiang Province, so as to provide the evidence for the development of fall intervention for the elderly.
Methods:
The permanent residents aged 60 years and over in Huzhou City were selected using multi-stratified cluster sampling method from March to April 2023. Demographic information, activity of daily living (ADL), fall risk, and KAP of fall prevention was collected using questionnaire surveys. Factors affecting KAP of fall prevention were identified using a multivariable logistic regression model.
Results:
Totally 2 160 questionnaires were allocated, and 2 104 valid questionnaires were recovered, with an effective recovery rate of 97.41%. There were 1 063 males (50.52%) and 1 041 females (49.48%), and 861 residents aged 60 to <70 years (40.92%). The awareness of fall prevention knowledge was 84.13%, the percentage of attitude towards fall prevention was 85.88%, and the percentage of practice of fall prevention was 14.59%. Multivariable logistic regression analysis showed that age, educational level, exercise duration and fall risk were associated with the awareness of fall prevention knowledge; age, educational level, marital status, exercise duration, ADL and fall risk were associated with the attitude towards fall prevention; gender, age, educational level, marital status, exercise duration, chronic diseases, ADL and fall risk were associated with the practice of fall prevention (all P<0.05). The desired access to fall prevention knowledge was mainly dominated by medical personnel, accounting for 75.51% (589/780).
Conclusions
The practice towards fall prevention among the elderly is relatively low in Huzhou City. The KAP of fall prevention is related to age, educational level, exercise duration and fall risk.

Objective:
To establish an evaluation index system for health education of hand,foot and mouth disease(HFMD)in nursery children by Delphi method.
Methods:
After referring to the relevant literature,an initial health education index system for HFMD of nursery children was established,including four first-level indicators,twelve second-level indicators and forty-six third-level indicators. Two rounds of expert consultation were conducted according to Delphi method. The enthusiasm of experts was evaluated by response rate,and the authority of experts was evaluated by authority and variation coefficient. The consultation questionnaire in the second round was based on the results of the first round and was scored again in the same way. Then the evaluation index system of HFMD health education for nursery children was finally determined.
Results:
Thirteen experts participated in two rounds of consultation,including four aged 40-49 years and nine aged 50-59 years;two of deputy senior title and eleven of senior title;one worked in the health administration department,six in the CDC,five in health education institutions and one in kindergarten. The two rounds of expert consultation were carried out effectively within the time set and the response rate reached 100%. In the first round,the judgment coefficient,familiarity coefficient and authority coefficient were 0.92±0.06,0.85±0.12 and 0.88±0.06,respectively. One first-level indicator,two second-level indicators and twelve third-level indicators were added,seven third-level indicators were deleted,and the contents of one second-level indicator and ten third-level indicators were improved in the first round. In the second round,the judgment coefficient,familiarity coefficient and authority coefficient were 0.95±0.07,0.88±0.10 and 0.91±0.06,respectively. The coordination coefficients of the first-,second- and third-level indicators in the second round were 0.170,0.166 and 0.283,respectively,and the coefficients of variation were all less than 0.25. After two rounds of discussion,five first-level indicators,fourteen second-level indicators and fifty-two third-level indicators were finally established as the evaluation index system of HFMD health education for nursery children.
Conclusion
The evaluation index system of HFMD health education for nursery children established by Delphi method has high authority and practicability,and it can be used to comprehensively evaluate the effects of HFMD health education on nursery children.

Objective To study interdialytic body weight gain(IBWG)in maintenance hemodialysis(MHD)patients,and to analyze the associated factors. Methods A total of 269 patients undergoing maintenance hemodialysis were enrolled in this cross-sectional study.The patients were divided into two groups according to the percentage of IBWG(PIBWG:interdialytic body weight gain/dry weight×100%):PIBWG>3.50%(190 cases)and PIBWG≤3.50%(79 cases).Associated factors of IBWG were analyzed. Results The average IBWG of 269 MHD patients was(2.42±1.01)kg(0-6.33 kg),and PIBWG was(4.25±1.79)%.In male patients,IBWG was (2.45±1.09)kg,and PIBWG was(3.99±1.79)%.In female patients,IBWG was(2.39±0.85)kg,and PIBWG was(4.64±1.74)%which was significantly higher compared to males(P<0.01).Patients with PIBWG<3.00%accounted for 20%,with PIBWG≥3.00%to<5.00%accounted for 50%,with PIBWG≥5.00%accounted for 30%.Compared to patients with PIBWG>3.50%,those with PIBWG≤3.50%were characterized by elder age(year)(60.50 ±14.49 vs 54.07±13.78),more males(70.88%vs 54.74%),shorter dialysis duration(month)(41.03±41.92 vs 58.83±43.57),larger BMI(kg/m2)(22.67±3.36 vs 20.91±3.25)and less dry weight(kg)(56.69±10.94 vs 62.82±10.97),more residual urine(ml,In)(6.19±0.94 vs 5.48±0.8),lower predialysis serum β2MG(mmol/L)(31.61±9.82 vs 38.54±10.38)and phosphorus(mmol/L)(1.92±0.66 vs 2.15±0.58).Correlation analysis revealed that PIBWG was positively correlated with dialysis duration,Scr,BUN,β2-MG,phosphorus,decrease and decrease percentage of BP during hemodialysis,and negatively correlated with age,dry weight,BMI,residual urine,and pre-dialysis SBP,MAP. Conclusions PIBWG of about 70%of our patients was below 5%.Young.female.low BMI and dry body weight,long dialysis duration,low residual urine,chronic glomerulonephritis and diabetic nephropathy are associated with more IBWG,which may lead to greater intradialytic BP fluctuation.
