Bone Mineral Density And Risk Factors Of Osteopor Osis In Dongxiang Nationality Of Gansu Province

objectiveBased on the investigation of bone mineral density,living habits,body composition and chronic diseases of Dongxiang People over 20 years old in Gansu Province,the situation and distribution of bone mineral density of Dongxiang people were understood,the risk factors of osteoporosis were analyzed,and data support was provided for the prevention and treatment of osteoporosis of ethnic minorities.methodThe subjects were residents over 20 years old(including 20 years old)and within three generations of Dongxiang Nationality in Longquan Township and Nalesi town of Dongxiang County,Gansu Province.A total of 570 people,245 men and 325 women,were enrolled in this study.The right calcaneal bone mineral density was measured by ultrasonic bone densitometer.According to the measurement results,the patients were divided into normal group,low bone mass group and osteoporosis group.At the same time,the living habits and nutritional status of the subjects were investigated by questionnaire.The liver and kidney were examined by abdominal ultrasound,the coronary heart disease was examined by ECG,the body composition was measured,and the liver and kidney function,fasting blood glucose and blood lipid were examined by blood biochemistry.Spss19.0 is used to analyze all valid data.Variance analysis is used for measurement data meeting normal distribution,non parameter test is used for non normal distribution,and 2 test is used for comparison between count data.Pearson correlation analysis was used to analyze the correlation between bone mineral density and body composition.The risk factors of osteoporosis were analyzed by logistic regression analysis,P < 0.05,the difference was statistically significant.result1.The prevalence of osteoporosis in Dongxiang adults is 7.2%(6.9% for men,7.4% for women).After 60 years old,the growth rate of women is significantly higher than that of men,and the prevalence of low bone mass in men is higher than that of women.2.There was no correlation between the bone strength of male and fat we ight,fat free weight,muscle weight,estimated bone mass,body water,protein,basic metabolic value,while that of female was correlated with fat free weight,muscle weight,estimated bone mass,body water,protein,basic metabolic value(P<0.05).3.Logistic regression results show that physical labor is the protective factor of Dongxiang men's bone health.4.Logistic regression results showed that the risk factors of osteoporosis were the increase of age and greasy diet.The normal waist hip ratio and muscle mass were the protective factors of osteoporosis.conclusion1.The prevalence of osteoporosis was 7.2%(male 6.9%,female 7.4%).2.6.9% of Dongxiang men and 23.9% of the population with low bone mass showed that their bone health was not good.Physical labor was the protective factor of male bone density,which could reduce the incidence of osteoporosis.3.The elderly,greasy diet,low muscle mass and high waist to hip ratio are the risk factors of osteoporosis in Dongxiang women,which can increase the risk of women's disease;young women,light diet,standard muscle mass and waist to hip ratio are the protective factors of bone density,which can reduce the risk of women's disease.4.The prevalence rate of Dongxiang men over 40 years old is higher than that of the Middle East,and that of women is lower than that of the Middle East.The prevalence rate of Dongxiang men and women in all age groups was lower than that of Mongolian,and there was no significant difference between Dongxiang and Middle East Gansu.
