用途：本人群研究旨在检查终生体力活动和生活方式参数对骨量的影响程度。方法：该项目的设计是一项为期27年的前瞻性随访研究。受试者为126名来自鲁汶生活方式、体能和健康纵向研究的男性，研究开始时年龄为13岁，随访结束时年龄为40岁。身体活动和生活方式参数通过问卷调查获得。通过双能X射线吸收法（DXA）测量骨质。结果如下：相关和回归分析的结果表明，体重指数（BMI）是最重要的参数，在每个检查阶段的骨皮质和骨小梁质量。纵向上，静态臂力、跑步速度和上肢肌肉耐力对成人骨量的预测有重要作用。18至13岁之间的参数"运动适应性的变化"被用来控制遗传影响。静态手臂力量和躯干肌肉力量的评分分别与成人总骨矿物质含量（BMC）和腰椎骨矿物质密度（BMD）显着相关。在40岁时，Baecke运动指数在解释BMD变化方面几乎与BMI同等重要，静态手臂力量是BMC最重要的参数（仅次于BMI）。结论：终身体力活动，身体素质和BMI都有助于成人骨量。这些发现的临床相关性强调的事实是，观察到的模式的身体活动和运动健身属于习惯的生活方式，因此是可行的目标。
Purpose: The present population study is conducted to examine the extent to which lifetime physical activity and lifestyle parameters contribute to bone mass. Methods: The design of the project is a 27-yr prospective follow-up study. Subjects are 126 males gathered from the Leuven Longitudinal Study on Lifestyle, Physical Fitness and Health, and aged 13 yr at the onset of the study and 40 at the end of the follow-up. Physical activity and lifestyle parameters are obtained with questionnaires. Bone mass is measured by means of dual-energy x-ray absorptiometry (DXA). Results: Results from correlation and regression analyses show that the body mass index (BMI) is the most important parameter in relation to cortical and trabecular bone mass at every examination period. Longitudinally, static arm strength, running speed, and upper muscular endurance contribute significantly to the prediction of adult bone mass. The parameter "change in motor fitness" between 18 and 13 yr old was used to control for hereditary influences. The score for static arm strength and trunk muscle strength demonstrates a significant correlation with adult total bone mineral content (BMC) and lumbar bone mineral density (BMD), respectively. At the age of 40, the Baecke sports index is almost equally important as BMI in explaining the variance in BMD, and static arm strength is the most important parameter (after BMI) for BMC. Conclusion: Lifetime physical activity, physical fitness, and BMI all contribute to adult bone mass. The clinical relevance of these findings is emphasized by the fact that the observed patterns of physical activity and motor fitness pertain to customary lifestyle and are thus feasible targets.
