The influence of blood Lipid and BMI in bone mineral density of the lumbar spine and concurrence of carotid artery plaque in elderly men

Objective The purpose of this study was to learn the risk factors of the concurrence of osteoporosis and carotid artery plaque formation,through exploring the influence of blood lipid and BMI in decrease of bone mineral density and in formation of carotid artery plaque.Methods Han nationality male patients aged 60-80 years old were selected.The patients with diabetes,hyperparathyroid,chronic liver and kidney dysfunction,and those administered with drugs associated with bone metabolism or artery plaque formation in last 6 months,were excluded.Subjects were divided into normal control group(group A),carotid artery plaque formation group(group B),BMD decrease group(group C),and BMD decrease with carotid plaque formation group(group D),according to results of BMD and carotid artery color Doppler ultrasound examination.The blood lipid levels and BMI were measured and compared among the four groups.Results ① BMI among the four groups were compared.The differences between group A and C,and between group A and D,were statistically significant.Patients with declined BMD showed lower BMI.BMI,to some extents,might be a protective factor of BMD.② Mean values of TC among the four groups were: Group D B A C.The differences between group A and D,between group C and D,were statistically significant.The difference between group A and D might be caused by the formation of carotid artery plaque.③ TG showed no statistical difference among the groups.④ HDL and LDL were no significant difference among the groups.Conclusion We could not confirm that BMI and lipid levels were risk factors of concurrence of decreased BMD and arterial plaque formation.
