Abstract:
Objective:To investigete the relationship between different physical activity(PA)and bone mineral density(BMD)at various skeletal sites,providing evidence for the prevention and improvement of bone health.Methods:Cross-sectional data from the National Health and Nutrition Examination Survey(NHANES)from 2007 to 2018 was used,and 7 692 participants aged≥20 were included.Multivariable linear regression model was used to analyze the relationship between different PA and BMD at the femoral neck,total hip,and lumbar spine across different genders.Statistical modeling employed a sequential variable inclusion approach:Model 1 included age,race/ethnicity,and body mass index,while Model 2 further incorporated calcium intake,marital status,smoking status,dietary inflammatory index,and serum phosphate levels.Results:PA showed statistically significant differences across age,gender,body mass index,race,marital status,smoking,and dietary inflammatory index(P＜0.05).Among females,low-intensity PA showed a positive association with femoral neck BMD in both Model 1 and Model 2(P＜0.05),but no significant correlation was found between low-intensity PA and total hip BMD(P＞0.05).High-intensity PA exhibited an inverse association with femoral neck and total hip BMD(P＜0.05),though this was only observed in Model 1.No significant association was detected between different PA intensities and lumbar spine BMD(P＞0.05).Among males,high-intensity PA showed a positive correlation with lumbar spine BMD(P＜0.05),but this association was only significant in Model 2.No significant association were observed between low-intensity PA and lumbar spine BMD in either Model 1 or Model 2(P＞0.05).Additionally,no significant association were found between different PA intensities and femoral neck or total hip BMD(P＞0.05).Conclusions:The relationship between PA and BMD varies by sex and skeletal site.Low-intensity PA is positively associated with femoral neck BMD in females,while high-intensity PA is positively correlated with lumbar spine BMD in males.
