Objective·To compare the physical activities of stroke population and non-stroke population based on the baseline survey of the elderly population cohort in Shanghai communities,and explore the participation in different types of physical activities of stroke population.Methods·The subjects were screened from Shanghai Community Elderly Cohort constructed from February to August,2019 according to the admission criteria.The subjects were divided into non-stroke group and stroke group according to whether they had reported a history of stroke by themselves,and the two groups were matched 2 to 1 by controlling age and sex with propensity score matching.The baseline characteristics of the two groups were collected,and the physical activities related to sports,transportation and housework in the last week were investigated with the International Physical Activity Questionnaire(IPAQ).Pittsburgh Sleep Quality Index(PSQ1)was used to evaluate the sleep quality of the subjects.Generalized Anxiety Disorder(GAD-7)and Patient Health Questionnaire-9(PHQ-9)were used to evaluate anxiety and depression of the subjects,respectively.The above characteristics were compared between the stroke group and non-stroke group,and the participation of different types of physical activities were compared between the two groups by multivariate Logistic regression model.Results·Among the 17 948 people included,there were 993(5.5％)in the stroke group and 16 955(94.5％)in the non-stroke group.After propensity score matching,there were 1 984 people(66.7％)in the non-stroke group and 992 people(33.3％)in the stroke group.There were significant differences in education level,pre-retirement occupation,waist circumference,body mass index,sleep status,anxiety symptoms,depression symptoms and disease history between the two groups(all P＜0.05).In terms of physical activities,the female stroke group had shorter daily moderate exercises time,fewer riding and walking days in one week,and shorter daily riding time,compared with the non-stroke people,with statistical significance(all P＜0.05).Compared with the non-stroke people,the weekly housework days and daily housework time in the male and female stroke groups were lower than those in the non-stroke group,while the daily sedentary time was longer,with statistical significance(all P=0.000).In terms of physical activity level,the proportions of men and women in the stroke group who reached medium or high level were lower than those in the non-stroke group,and the differences were statistically significant(all P=0.000).After adjusting for gender,age,occupation,anxiety symptoms,history of hyperlipidemia,history of atrial fibrillation,history of chronic gastritis and history of hip fracture by multivariate Logistic regression model,the level of vigorous exercise participation in the stroke group was lower,the proportions of no housework in the last week and sedentary time greater than 180 min per day were higher,and the proportion at medium and high activity levels was lower(all P＜0.05).Conclusion·The frequency and duration of housework participation and the physical activity level of elderly people with a history of stroke in Shanghai communities are at a lower level than those without stroke,and they also have a longer sedentary time.

Objective·To analyze the epidemiological characteristics of risk factors for cardiovascular diseases and malignant tumors based on the Shanghai community elderly cohort.Methods·The study subjects were selected from the Shanghai community elderly cohort established from February to August 2019,with a total of 17 948 people.The study subjects were divided into 4 groups according to self-reported presence or absence of tumors and/or cardiovascular diseases during the baseline survey:tumor-free and non-cardiovascular disease group,single cardiovascular disease group,single tumor group and tumor cardiovascular disease co-occurrence group.The differences among the four groups of subjects were collected and compared in terms of demographic characteristics and physiological indicators,daily living habits(smoking,drinking tea,drinking coffee,drinking carbonated drink,drinking alcohol,sedentary time,physical activity level and sleep quality),past medical history,psychological status(depression and anxiety)and dietary compliance.Results·Among the study subjects,60.1%of tumor patients were complicated with cardiovascular diseases.The differences among the four groups of subjects in age,gender,educational level,pre-retirement occupation,waist circumference,hip circumference and body mass index were statistically significant(all P<0.05).Compared with the tumor-free and non-cardiovascular disease group,the single cardiovascular disease group,single tumor group and tumor cardiovascular disease co-occurrence group all exhibited lower proportions of smoking and high physical activity levels(all P<0.05),and higher proportion of sedentary time exceeding 4 h/d and poor sleep quality(all P<0.05);the proportion of subjects with past medical histories including hyperlipidemia,peripheral vascular disease,endocrine system disease,respiratory system disease,urinary system disease and digestive system disease of the single cardiovascular disease group and the tumor cardiovascular disease co-occurrence group was higher(all P<0.05),and the proportion of subjects with depression and anxiety was also higher(all P<0.05).Furthermore,compared with the tumor-free and non-cardiovascular disease group,the single cardiovascular disease group had lower compliance rates of poultry,fish,fruit and liquid milk(all P<0.05).Among the four groups,only the compliance rate of vegetable intake exceeded 50%,while the compliance rates of poultry,fish,fruit,liquid milk and tubers were all below 20%.Conclusion·In the elderly population of Shanghai communities,over half of malignant tumor patients are concomitant with cardiovascular diseases.Unhealthy daily habits are prevalent among those with cardiovascular diseases,tumors and tumor-cardiovascular disease co-occurrence.The intake of many foods in the elderly of the community do not reach the levels recommended by Chinese Dietary Guidelines.

In order to facilitate the accurate comprehension and correct implemention of the national occupational health standard Health standard for operators of nuclear power plants (GBZ/T 164-2022), this article presents an in-depth elucidation encompassing the significance of the standard promulgation, the background of its revision, the current status of the relevant domestic and international standards, the basis for revision of the principal technical inclusion and the application scope of the standard. The aim is to provide a guidance the selection, appropriate evaluation, and occupational health monitoring of nuclear power plant operators, ultimately ensuring the safe operation of nuclear facilities.
