Correlation Between Fall Risk And Body Composition In Tibetan Population In Tibet

ObjectiveIn order to explore the correlation between fall risk and body composition in Tibetan population in Tibet,the body composition of Tibetan population in Tibet was measured and analyzed,and the prediction effect was provided for the occurrence of fall risk in Tibetan population in Tibet.It also provided data for the theoretical research,and provided the basis for improving the health level of Tibetan population.MethodsWith informed consent,the Tibetan population over 40 years of age in Shigatse and Lhasa of Tibet,was selected by cluster sampling method as the object of study.which required that all the three generations should be Tibetan,and that the object of study should be aware of it and can walk independently.The general situation questionnaire and fall risk assessment scale were used to investigate the selected subjects and evaluate the risk of falling.705 valid data were obtained,of which 248 cases were male and 457 cases were female.The body composition and bone mineral density of the subjects were measured by bioelectrical impedance analyzer and ultrasonic bone densitometer.The data were imported into the Ogilvy&Mather Health Fitness Management system.The data were sorted out and compared with each other by SPSS17.0 software.Descriptive analysis,independent-samples t test,univariate analysis(?~2 test)and binary logistic regression analysis were used to analyze the correlation between fall risk and body composition,and thus to predict the occurrence of fall risk in Tibetan population in Tibet.Results1.The reliability and validity of the scale used in this paper are better,the Cronbach coefficient?is 0.889 and the validity is 0.875.2.In this study,the prevalence rate of fall risk of Tibetan population in Shigatse and Lhasa was 24.5%.3.There was a significant difference in the detection rate of fall risk among different age groups,and the detection rate of fall risk was significantly increased with the increase of age.4.The results of univariate analysis showed that gender,age group,the number of falls in the past year,medication and physical exercise were the influencing factors of the risk of falling down among Tibetan population in Tibet.The OR values of relative risk were 0.527,2.601,6.986,2.326and0.536,respectively.Moreover,the number of falls in the past year had the greatest effect on the risk of falls,that is,the more falls in the past year,the greater the risk of falls.5.There was a significant difference between the two groups in the left upper limb muscle weight and the right upper limb muscle weight(P<0.05),and there was a significant difference between the two groups in the risk offalling down.Women were at risk of falling down in two groups:height,weight,body mass index,lean body mass,body fat,left upper limb fat,left lower limb fat,right upper limb fat,right lower limb fat,whole body muscle mass,trunkmuscle mass.There were significant differences in muscle weight of left upper limb(P<0.05),left lower limb,right upper limb and right lower limb,and allbody components in the risk-free group were higher than those in the risk group.6.There was a significant difference in the detection rate of the risk of falling between male and female(P<0.05),and the proportion of osseous perforation and osteoporosis in the group with risk of falling was higher than that in the group with risk of falling.The difference of T value,bone strength index and fracture risk between male and female were statistically significant(P<0.05),and the T value and bone strength index of non-fall risk group were higher than those of fall-risk group,and the bone strength index of male and female were higher than that of fall-risk group,and the difference of bone strength index and fracture risk was statistically significant between male and female.The risk of fracture was lower than the risk of fall.7.According to the comprehensive logistic analysis of body composition and bone mineral density,the variables of male model were trunk muscle mass,T value and left upper limb muscle mass,except for constant,there was no significant difference(P>0.05).The rest were statistically significant(P<0.05),and the OR values of relative risk were 1.220,0.399 and 0.089,respectively,indicating that trunk muscle volume was the risk factor of fall in Tibetan men.T value and left upper limb muscle mass were the protective factors of fall risk in Tibetan men,and the left upper limb muscle meat had the greatest effect on the risk of fall,that is,the less the muscle meat of the left upper limb,the greater the risk of fall.The variables of the female model were muscle mass and bone strength index of the right lower extremity,which were statistically significant(P<0.05).The OR values of the relative risk were0.484 and 0.936,respectively.The results showed that the muscle mass and bone strength index of the right lower extremity were the protective factors of fall risk in Tibetan women,and the muscle quantity of the right lower extremity had the greatest effect on the risk of falls.The less the muscle content of the right lower extremity,the greater the risk of falling.Conclusions1.Tibetan males and females,with age,increased the risk of falling down.2.The bone mineral density(BMD)of the non-fall risk group was higher than that of the fall risk group.3.Sex,age group,number of falls in the past year,medication,physical exercise had an impact on the risk of fall in Tibetan population,and the risk of fall in women was higher than that in men.The older you get,the more times you fall in the past year,the more you take,the less physical exercise,and the higher the risk of falling.4.The fall risk of men in Shigatse and Lhasa areas in Tibet was related to the trunk muscle mass,T value and left upper limb muscle weight.The left upper limb muscle weight had the greatest influence on it,that is,the less the left upper limb muscle weight,the greater the risk of falling to the left upper limb muscle.The risk of fall was related to the muscle mass and bone strength index of the right lower limb,and the right lower limb muscle weight had the greatest influence on it,that is,the less muscle content of the right lower limb,the greater the risk of falling down.
