| Objective: To understand the current status of physical activity and aging of the 40-59 year-old adult population,and to explore the relationship between physical activity and aging.The purpose is to provide a theoretical basis for promoting national fitness and sports to promote health.Provide suggestions and references for people with different occupational types to delay aging and promote health.Methods:1."Physiological-Psychological-Social Three-dimensional Human Aging Scale",which is highly operable and has wide applicability,is used to investigate the aging status of people aged 40-59.Through calculation,the standardized scores of aging degree and the standardized scores of aging degree in physiological,psychological and social dimensions are obtained respectively,and the grade of aging degree is judged by combining with the percentile aging degree judgment tool table.2.Use the "International Physical Activity Questionnaire IPAQ(Long Version)" to survey the subjects’ different types of physical activity,different intensities of physical activity,and the sitting and sleeping time of the surveyed population,and calculate the total energy consumption of PA,The energy consumption of different intensities of PA,the energy consumption of different types of PA,and the PA level of the population.3.Enter the measured data such as physical activity and aging degree into Excel,and sort,assign and calculate the data,and then enter the calculated data such as physical activity,aging degree and scores of various dimensions into the software SPSS22.0 conduct statistical analysis.Descriptive analysis shows the physical activity and aging of adults aged 40-59,and uses correlation analysis to find the correlation between physical activity level,physical activity type,physical activity intensity,and sedentary time,sleep time and aging Finally,the multiple regression method is used to analyze the influence of PA on the aging degree.Multivariate regression of control variables is adopted to control demographic variables such as age,BMI,monthly income,and whether or not to drink alcohol.The level of physical activity,intensity of physical activity,type of physical activity,total sitting time,and total sleep time are included in the regression equation for hierarchical regression.Results:(1)Among the surveyed population,there are 64 people who insist on physical exercise for 30 minutes each time three times a week,accounting for 43.5%of the total number,less than half,and the proportion of overweight and obese people in the population is 60.5%.The different types of physical activity consumption of adults aged 40-59 are the average occupational physical activity energy consumption(1680.971713.81)MET-min/week> leisure physical activity energy consumption(1302.881283.58)MET-min/ week>average energy consumption of physical activities for transportation(426.96462.02)MET-min/week> total energy consumption of housework activities(419.63520.66)MET-min/week,and in addition to the energy consumption of leisure activities,other categories There are significant differences in the amount of physical activity between men and women;(2)The physical activity of 40-59-year-old adults of different intensities,in order of the average amount of moderate-intensity physical activity> total amount of low-intensity> high-intensity activity level.The order of low-intensity energy consumption in each physical activity type is leisure(459.76±481.97)MET-min/week> occupational(437.98±522.67)MET-min/week> transportation(321.24±319.32)MET-min/ week;the order of the components of medium-intensity energy consumption is: medium-intensity activity value in leisure category>moderate-intensity activity value in work>medium-intensity activity value in housework>medium-intensity activity value in traffic category;high-intensity energy consumption The order of the components is: occupational high-intensity activity value>leisure exercise>housework activity.With the increase of age,high-intensity physical activity decreases in turn.(3)The total PA of the surveyed population is(3830.44 ± 1572.10)MET-min/week,and there is no significant difference in gender;(4)In terms of the total physical activity level of the surveyed population,66.0% of the physical activity levels are high-level,and only 14.5% of men and 5.1%of women are low-level physical activity.(5)Current status of aging and demographic differences: the average total score of aging for the 40-49 age group is 36.71 points,and the average for the 50-54 age group is 41.42 points;55-59 The average total score of age group is 43.80 points;with the increase of age,the overall aging degree and the aging degree of the physiological dimension show an obvious increasing trend,while the scores of the psychological and social dimensions and the age increasing trend are not obvious.There are no significant differences in the total scores of aging and physical and psychological dimensions of different genders(p>0.05),and there are significant differences in the scores of social dimensions(p<0.05);different monthly incomes,different types of occupations,total scores of aging and physiological dimensions There are extremely significant differences in social dimension scores(P<0.001).The aging degree with a monthly income >5000 is the lowest,and the aging degree with a monthly income <1800 is the highest.There are extremely significant differences in the total aging score and physiological scores of people of different ages(p<0.001)),the older the age,the higher the aging degree score;whether drinking is significantly different from the physiological and social dimensions of aging degree and aging degree(p<0.05),the order of aging degree is frequent drinkers> occasional drinkers>never Drinkers: There are significant differences in the aging degree of people with different BMI indexes,the higher the aging degree score is for the BMI>24.0;(6)The results of the correlation between PA and aging degree showed that the total energy expenditure of physical activity and the total score of aging degree of the 40-59 year-old population showed a very significant negative correlation,(r=-0.574,p<0.001);In the physical activity type,occupational physical activity is significantly negatively correlated with aging,and the total amount of physical exercise activity is extremely significantly negatively correlated with the total score of aging and each dimension(r=-0.398,p<0.001);different Intensity of physical activity is moderately negatively correlated with the total score of aging and the scores of physical and psychological dimensions;the total score of aging is extremely negatively correlated with middle and high-level physical activity;total sitting time is negatively correlated with aging,physical and psychological dimensions The dimensional score becomes a significant positive correlation;(7)Regression analysis: After controlling for age,monthly income,BMI,drinking or not,the predictive degree of physical activity level for aging is 59.0%(R2=0.590),and it is significantly negatively correlated with aging(β=-0.311,p<0.001).The predictive degree of physical activity intensity on aging degree was65.2%,and moderate-intensity physical activity was significantly negatively correlated with aging degree((β=-0.306,p<0.001)).The type of physical activity predicts the degree of aging is 66.8%(β=-0.306,p<0.001),and the amount of leisure physical activity can predict the degree of aging the most(β=-0.433,p<0.001),the total length of sitting has an effect on aging The predicted degree of aging is 56.2%,and the total time of sitting still is significantly positively correlated with aging(β=0.262,p<0.001).Conclusion:(1)More than half of the surveyed population has reached the recommended amount of physical activity,and the overall level is of medium to high physical activity.Among them,leisure and professional physical activities account for a large proportion of total energy consumption,and the intensity of physical activity is mainly concentrated in low and medium intensity.Intensity physical exercise is less involved,and exercise frequency is different and uneven;(2)With the increase of age,the total score of aging of the surveyed population showed an upward trend,among which the physiological aging trend was particularly significant;the total scores of aging of different genders,smoking and supplementary health products,and scores of physiological and psychological dimensions did not Significant differences,The higher the monthly income level,the lower the scores of the aging degree and the physiological and social dimensions of the aging degree of the people who do not drink alcohol frequently;(3)There is a significant negative correlation between adult’s total physical activity energy consumption and aging degree and its various dimensions.In particular,leisure physical activity can significantly affect human aging degree and aging in all dimensions.Middle-to-high-intensity physical activity are significantly negatively correlated with aging.The aging degree of the middle-high-level physical activity group is significantly lower than that of the low-level group;(4)The length of sitting still has a significant positive correlation with the degree of aging.The longer the sitting time is,the greater the degree of aging changes,especially the physical and psychological dimensions.Recommendation:(1)People with low levels of physical activity should pay attention to their physical activity levels from work,transportation,housework,leisure and entertainment,and consciously increase the amount of physical activity,reduce sedentary behavior and time;especially increase high-intensity physical strength in leisure classes Activities,maintain a normal BMI,and develop good work and rest habits;(2)The prevention and delay of aging should first focus on preventing the decline of physiological function and physical function.For employees,they should maintain the activity intensity at work,maintain sufficient physical energy,and increase walking and leisure sports activities in their spare time to enhance their health.Physical fitness and extend the age of the labor force;for the unemployed people living at home,they should maintain a certain amount of housework activities,avoid all relying on various smart appliances to replace housework physical activities,and transportation should also choose walking activities or cycling;(3)Moderate and high-intensity physical activity levels are significantly negatively correlated with aging.It is recommended that people who do not usually do moderate activities increase moderate-intensity activities(work,housework or physical exercise),and those who regularly participate in moderate-intensity people should increase their physical activity intensity.(4)Increasing the total physical activity by increasing the frequency of weekly activities and/or the duration of each activity,especially increasing the amount of leisure sports activities and reducing the sitting time,can significantly reduce aging and maintain a younger state.(5)Social group organizations and management should pay attention to the level of physical activity and aging of different populations in the region.It is recommended that each community or area have a set of citizens’ physical health monitoring sites,with professionals and equipment that regularly monitor and store citizens’ physical health data,so that Everyone can intuitively see the dynamic changes of their physical fitness and physiological function indicators in each period,and take targeted intervention measures to keep people as low as possible to maintain a constant aging rate,so as to delay aging and improve The purpose of healthy life span. |
