Correlation between Bone Density at Different Hip Positions with Muscle Parameters and Physical Performance in Middle-aged and Elderly People in Kunming Area
摘要
Abstract
Objective To investigate the correlation between bone mineral density(BMD)at different hip positions with muscle parameters and physical performance in middle-aged and elderly people in Kunming area.Methods 531 middle-aged and elderly volunteers were recruited from the Radiology Department of the First People's Hospital of Yunnan Province from May 2021 to April 2022.All study subjects completed the five-times-sit-to-stand test(FTSST)and hip quantitative CT(QCT)examinations.Volunteers'total hip(TH),femoral neck(FN),and intertrochanteric(IT)BMD were measured by using QCT PRO workstation and using OsiriX software to measure the area and density of their gluteus maximus muscle,gluteus medius,and minimus muscle and midthigh muscle.Divide male and female volunteers into positive and negative groups respectively based on FTSST time≥12 seconds or<12 seconds,and analyze the differences in hip BMD between the groups;Also divide male and female volunteers into three groups(50～59 years old,60～69 years old,70 years old and above)at the age of 10,and analyze the correlation between hip BMD and muscle parameters in different age and gender stratification.Control for age and BMI,and then perform partial correlation analysis on the above indicators.Results The BMD of the hip in the female FTSST positive group was lower than that in the negative group(P<0.001),while there was no statistically significant difference between the male groups(P>0.05).After adjusting for age and BMI,among males,FN BMD was positively correlated with gluteus medius and minimus muscle density in the age groups of 50～59 and 60～69(P<0.05),while TH BMD,FN BMD,and IT BMD were strongly positively correlated with gluteus medius and minimus muscle density in the age group over 70(P<0.05).For females,the correlation between hip BMD and muscle density in the age groups of 50～59 and 60～69 was weak,while BMD in all parts of the hip was not correlated with muscle density in the age group over 70(P>0.05).There was a negative correlation between TH BMD,FN BMD,and gluteus medius and minimus muscle area in the age group of 50～59 years old for males(P<0.05),while there was a significant negative correlation between TH BMD,IT BMD,and gluteus maximus area in the age group of 70 years old and above for females(P<0.05).Conclusion The BMD of various parts of the hip in the female FTSST positive group is lower than that in the negative group.The density of the gluteus medius and minimus muscle can to some extent serve as a predictive indicator of femoral neck bone strength in middle-aged and elderly men in Kunming area.关键词
