Study On Sarcopenia,physical Activity,nutritional Status And Their Relationship Among The Elderly

Objective: In this study,by screening for sarcopenia in the elderly in Chengdu Zhiguan District,Tianfu New District,collecting their physical activity and nutritional status,to explore the relationship between physical activity,nutritional status and sarcopenia in the elderly.Methods: In this study,250 elderly people aged 60 and above in the Chengdu Direct Management District,Tianfu New District,Chengdu City,Sichuan Province were selected as the survey subjects,using the "SACR-Cal F Scale","International Physical Activity Scale(short volume)" and " The Mini Nutritional Assessment Scale" conducts a questionnaire survey on the prevalence,physical activity,and nutritional status of the elderly with sarcopenia.At the same time,their height,weight,and calf circumference are measured,and the measured data are sorted,and the normal distribution is used for The mean ± standard deviation((?)±SD)is expressed in the form;the measurement data of skew distribution is described by the median(interquartile range)[M(P25,P75)].For the differences between groups of categorical variables,the chi-square test was used to analyze;for the differences between two groups of continuous variables,the independent sample t test was used for analysis.The correlation is analyzed using Spearman’s correlation analysis method.Results:(1)The total physical activity of the elderly(weekly energy expenditure)was 1296.0(822.0,1589.0)MET-min/w,and there was no gender difference(P>0.05);the proportion of physical activity at a moderate level was as high as 90.32%,there is no gender difference(P>0.05);the meditation time of the elderly is 4(4,5)h/d,there is no gender difference(P>0.05).(2)The total score of the nutritional scale for the elderly was 11.63±1.31,male was 11.86±1.31,and female was 11.15±1.30.There were gender differences(P<0.05).Among the nutritional grades,the risk of malnutrition accounted for the highest proportion,reaching 74.6%.(3)The prevalence of sarcopenia in the elderly was 12.10%.Among them,the prevalence of women was 16.18%,and the prevalence of men was 7.14%.There was a gender difference(P<0.05).(4)The correlation coefficient between the prevalence of sarcopenia and physical activity in the elderly is r=-0.21(P<0.05);there is no significant difference between the prevalence of sarcopenia in the elderly and the sitting time(P>0.05).The correlation coefficient between the prevalence of sarcopenia and nutritional status in the elderly was r=-0.54(P<0.01).Conclusion:(1)There is no gender difference in the physical activity of the elderly.(2)The nutritional status of the elderly is not optimistic.The nutritional status of men is better than that of women.(3)The prevalence of sarcopenia in the elderly is higher in women than in men.(4)There is a weak negative correlation between the physical activity of the elderly in Chengdu Zhiguan District,Tianfu New District,Chengdu and the prevalence of sarcopenia;there is a moderate negative correlation between the nutritional status of the elderly and the prevalence of sarcopenia;There is no statistically significant correlation between human physical activity and nutritional status.
