| Objective: The study is to investigate the characteristics of bone mineral density,body composition,metabolic diseases and living habits of Maonan,Yao and Hmong adults in Guangxi,to analyze the status of local residents' bone mineral density and ethnic differences,to explore risk factors for osteoporosis,in order to provide scientific basis for the prevention and treatment of osteoporosis in ethnic minority adults and improve their quality of life.Methods: A total of 425 healthy Maonan adults(178 males and 247 females)in Huanjiang county,565 healthy Yao adults(293 males and 272 females)in Dahua county and 415 healthy Hmong adults(206 males and 209 females)in Rongshui county were selected randomly.All three generations of participants are the same minority.The BMD of the right calcaneus was measured in all participants using an ultrasound bone densitometer.The body composition was measured in all participants by a body composition analyzer.Blood pressure and blood lipids were measured.Basic characteristics of all participants were collected.Results: 1.Ethnic differences:(1)Bone quality index(BQI)and T-value: regardless of male,female or whole group,the BQI and T-value are the highest in Yao nationality,followed by the Hmong ethnic group,and the lowest in Maonan nationality(P<0.01).There were significantly statistical differences among all ethnic groups(P<0.05).(2)Prevalence of osteoporosis(OP): The OP is the lowest in Yao nationality,followed by Hmong,and that is the highest in Maonan nationality(P<0.01).There were significantly statistical differences among all ethnic groups(P<0.05).2.Gender differences:(1)BQI: The BQI of male was higher than that of female among Maonan,Yao and Hmong nationalities.The differences between male and female have significantly statistical significance in the Maonan and Yao nationalities(P<0.01).(2)T-value: The T-value of male was higher than that of female among Maonan nationality,while was lower than that of female in the Yao and Hmong nationalities.Among them,the gender difference of T-value has significant statistical significance among Hmong nationality(P<0.01).(3)Prevalence of osteoporosis(OP): The OP of male was lower than that of female among Maonan nationality,while was higher than that of female in the Yao and Hmong nationalities.However,there was no statistical difference in the prevalence of osteoporosis between men and women in different ethnic groups(P>0.05).3.Changes of age: With age,the prevalence of osteoporosis among men and women of all ethnic groups showed a gradual increase or a wave-like rise,which peaked in 70 years or above.4.Risk factors: Correlation analysis found that there was a significantly positive correlation between bone mineral density and weight,fat-free mass,percentage of body fat,trunk muscle mass and limb muscle mass(P<0.05);Logistic regression analysis found that hypertension was a risk factor for osteoporosis after adjusting for ethnicity and age,etc.Conclusions: 1.Ethnic difference of the prevalence of osteoporosis was found in this study.Maonan(both men and women)was more prone to osteoporosis than Yao and Hmong.2.There was a gender difference in the bone mineral density.The bone mineral density of men in Maonan and Yao was better than that of women,while that of men in Hmong was lower than that of women.3.With age,the prevalence of osteoporosis in 40 years increased gradually in males and females among three ethnic groups.4.Participants with hypertension were more likely to suffer from osteoporosis. |
