Abstract：Objective To investigate the relationship between sarcopenia assessing skeletal muscle index(SMI),muscle strength,physical function and osteoporosis(OP)assessing bone mineral density(BMD).Methods A total of 83 patients treated in author's hospital from January 2022 to August 2023 were enrolled in this study.All the patients were scanned by dualenergy X-ray absorptiometry(DXA)to measure patients'BMD,all the patient were divided into normal bone mass group(n=27),osteopenia group(n=26)and OP group(n=30)according to the results.The differ-ences of SMI,right hand grip,left hand grip,6 m walking time and 5 times sitting time were measured in each group.The correlation between SMI,muscle strength,physical function and BMD was analyzed by Pearson correlation analysis.Results There were significant differences in SMI,right hand grip,left hand grip,6 m walking time and 5 times sitting time among the 3 groups(all P＜0.01);SMI and right hand grip,left hand grip were positively correlated with BMD in different sites,while 6 m walking time and 5 times sitting time were negatively correlated(all P＜0.001).Conclusion Sarcopenia can increase the risk of osteoporosis,people with higher SMI,muscle strength and better physical function have a lower probability of osteoporosis.
