文题释义:
骨密度:骨密度是指骨骼矿物质的密度,是反映骨骼强度的一个重要指标,是诊断骨质疏松症的可靠指标。一般用以g/cm3表示,是一个绝对值。
身体活动水平:身体活动是由骨骼肌工作并消耗能量的任何身体动作,身体活动问卷是测量身体活动水平的常用方法。身体活动水平反映身体活动量的大小。
摘要
背景:
骨密度是判断人体骨质水平的最主要指标。骨质疏松是个世界性难题,目前没有安全有效的根治方法,只能进行预防,需要从影响骨密度的因素着手。
目的:探究中老年人骨骼肌含量、身体活动水平与骨密度之间的关系,为预防骨质疏松的发生提供理论依据。
方法:随机招募了年龄范围40-84岁的111名受试者。采用问卷调查掌握受试者身体活动水平等基本情况,采用双能X射线骨密度仪测量骨密度值,用人体成分分析仪测量人体的骨骼肌含量、脂肪含量、骨骼肌百分比等身体成分指标。不同年龄段的多组比较采用方差分析,组间两两比较采用LSD法,相关性分析采用Pearson相关分析。
结果与结论:①骨密度与身体活动水平、体质量和骨骼肌含量存在中低度相关关系(r=0.30,0.41,0.45),相关性检验差异具有显著性(P < 0.01);②对于中老年人,骨骼肌含量、身体活动水平和体质量与骨密度呈正相关,年龄与骨密度呈负相关;③结果提示,身体活动是影响骨密度的重要因素,较高的身体活动水平有利于骨密度保持和提高。增加肌肉量改善身体成分对增加骨密度具有促进作用。

Abstract:

BACKGROUND: Bone mineral density is the most important indicator for bone level. Osteoporosis is a worldwide problem, and there is no safe and effective radical treatment. It can only be prevented, so bone mineral density arise more attention.
OBJECTIVE: To explore the relationship between skeletal muscle content, physical activity level and bone mineral density in older adults, so as to provide theoretical basis for preventing osteoporosis treatment.
METHODS: Totally 111 subjects aged 40 to 84 years were recruited randomly. The bone mineral density was measured by double energy X-Ray bone density meter, and the human skeletal muscle content, fat content and percentage of skeletal muscle were measured by human body component analyzer. The variance analysis was used for multiple group comparisons in different age groups, LSD method for comparisons between groups, and Pearson correlation analysis for correlation analysis.
RESULTS AND CONCLUSION: Bone mineral density was significantly related to the physical activity, body mass, and skeletal muscle content (r=0.30, 0.41, and 0.45, P < 0.01). For middle and older adults, skeletal muscle content, physical activity level and body mass were positively related to bone mineral density. Age and bone mineral density had a negative relationship. These results indicate that physical activity is an important factor affecting bone density, and higher level of physical activity is beneficial to maintain and improve bone mineral density. Increasing muscle mass and improving body composition can improve bone mineral density.
