Relationship between bone mineral density and metabolic syndrome in men / 中国医师杂志

ABSTRACT

Objective:To investigate the relationship between bone mineral density (BMD) and metabolic syndrome (MS) and its components in men.Methods:The cross-sectional study method was used. The subjects were male physical examination population who were examined in the Health Examination Center of the Affiliated Hospital of Hebei University from January 2021 to December 2021. According to the MS diagnostic criteria, they were divided into MS and non MS groups. The BMD of femur was measured by dual energy X-ray bone density analyzer. The prevalence rate and bone mineral density of osteopenia, osteoporosis, metabolic syndrome in different age groups, and the differences of metabolic indicators between MS and non MS groups and the impact of MS on BMD were analyzed. Multivariate linear stepwise regression was used to analyze the risk factors of male bone mineral density.Results:6 191 subjects were included in the study. The prevalence of osteoporosis (OP) was 9.50%(588/6 191) and the prevalence of MS was 31.64%(1959/6 191) in healthy men. The prevalence of age, body mass index (BMI), fasting plasma glucose (FPG), total glyceride (TG), total cholesterol (TC), uric acid, diastolic blood pressure, systolic blood pressure and fatty liver in MS group were higher than those in non-MS group, with statistically significant difference (all P<0.05). The high density lipoprotein cholesterol (HDL-C) in MS group was lower than that in non-MS group, with statistically significant difference (all P<0.05). There were no significant difference in the prevalence of OP and BMD between the MS group and the non-MS group (all P>0.05). There was no statistically significant difference in BMD values among different MS groups, but after adjusting BMI, when the MS group score increased from 0 to 4, the BMD value decreased gradually, and the difference was statistically significant ( P<0.05). Multiple linear regression analysis showed that BMD was positively correlated with BMI and diastolic blood pressure, but negatively correlated with age, systolic blood pressure and prevalence of fatty liver disease (all P<0.05). Conclusions:With the increase of the number of MS components, BMD in men decreased gradually. BMD in men was positively correlated with BMI and diastolic blood pressure, but negatively correlated with age, systolic blood pressure and prevalence of fatty liver disease.
