ABSTRACT

OBJECTIVE@#To investigate the relationship between sleep quality and bone mineral density (BMD) in urban residents.@*METHODS@#Data of 28 756 Han adults (14 355 males and 14 401 females), who completed both Pittsburgh sleep quality index (PSQI) assessment and radial BMD tests by dual energy X-ray absorptiometry in the Health Management Center of Southwest China University from June 2012 to June 2019 were retrospectively analyzed. The degree of sleep disorder was determined based on PSQI scores, while osteopenia and osteoporosis was diagnosed according to BMD T-value. The test and multiple regression model were used to investigate the relationship between sleep quality and BMD.@*RESULTS@#The numbers of normal BMD, osteoponia and osteoporosis were 17 039 (59.3%), 7916(27.5%) and 3801(13.2%), respectively. The mean PSQI score was 5.6±1.4 points. According to PSQI scores, there were 15 936 subjects without sleep disorder (55.4%), 5965 with mild (20.7%), 4897 with moderate (17.0%) and 1958 with severe sleep disorder (6.8%), respectively. There was no significant difference in osteoponia/osteoporosis rate between subjects with mild sleep disorder and normal ones (=0.948, >0.05), while the rate of osteoporosis in moderate sleep disorder group was higher than that in mild group (=525.583, <0.01), and the rate of osteoponia/osteoporosis in severe sleep disorder group was much higher than that in moderate group (=1124.877, <0.01). Multiple regression results showed that female, elders, mental labor, smoking and higher PSQI scores were independently associated with lower T-value (all <0.05), while moderate to intense daily physical activity was associated with higher T-value (<0.05).@*CONCLUSIONS@#Sleep disturbances may be a major risk factor for BMD loss in urban residents, indicating that it would be a potential target of osteoporosis prevention.

ABSTRACT

Objective To study retrospectively the changes of bone mineral density,the prevalence of osteopenia/osteoporosis and risk factors in urban residents in Chongqing.Methods The data of radial bone mineral density of 9,158 healthy Han people (4 577 males and 4 581 females) who received health examination in the Health Management Center of Southwest China University were collected,from September 2012 to December 2016.Osteoporosis was judged according to T-value and the detection rate,BMI and OSTA indexes were calculated respectively.Results The total detection rate of osteoporosis in this group was 15.6% (9.5% in males and 21.6%in females,respectively).Among all the vocational groups,the detection rate of osteoporosis of teachers was the highest,while that of workers was the lowest.The detection rate of osteoporosis in the fcmales was higher than those in male,which in the emaciation group was much higher than those in the overweight/obesity group,among all the BMI status.The male over 70 years and female over 50 years belonged to the intermediate-risk group,which were also the focus for osteoporosis prevention and treatment.Conclusions The detection rate of osteoporosis in the urban residents in Chongqing is higher than those in other regions of China.Hence,Chongqing has a high-prevalence area of osteoporosis.Meanwhile,risk assessment using indexes such as vocation,BMI and OSTA and systematic intervention of osteopenia/osteoporosis for the urban residents are critical for the prevention and control of osteoporosis incidences.
