The comparative analysis of the osteometric dimensions of metacarpal bones in three groups of males (aged from 23 to 63 years) differing with respect to the presence of the professionally connected long-term exposure to the vibration is performed. The sample encompasses forest workers employed in wood industry (exposed to heavy physical work and to the daily use of hand-held vibrating tools) from two regions of Croatia: Podravina (n = 192) and Gorski Kotar (n = 115). The control group is formed using the random sample (selected according to age criterion) of phenotypically healthy male inhabitants of rural communities of Eastern Adriatic islands and peninsula (n = 200). Additionally, the influence of the level of calcium in diet, as a regional nutritional characteristic of particular regions of Croatia, is also considered. The regression of the percent cortical area (PCA) of the second left metacarpal bone and age showed that significant decrease of PCA in older age can be observed only in males from Eastern Adriatic (the control group), while that is not so in either group of males professionally exposed to vibration. Authors conclude that the analysis of the osteometric dimensions performed on males professionally daily exposed to vibration missed to provide evidence to support the hypothesis of long-term exposure to vibration as a risk for accelerated osteoporosis of metacarpal bones.
对三组男性(年龄在23岁至63岁之间)的掌骨骨测量尺寸进行了比较分析,这三组男性在是否长期职业性接触振动方面存在差异。样本包括来自克罗地亚两个地区的木材工业中的林业工人(从事繁重体力劳动且每天使用手持振动工具):波德拉维纳(n = 192)和戈尔什基科塔尔(n = 115)。对照组是使用亚得里亚海东部岛屿和半岛农村社区表型健康男性居民的随机样本(根据年龄标准选取)形成的(n = 200)。此外,还考虑了饮食中钙水平作为克罗地亚特定地区的区域营养特征的影响。左第二掌骨的皮质面积百分比(PCA)与年龄的回归分析表明,仅在亚得里亚海东部的男性(对照组)中可以观察到老年时PCA的显著下降,而在两组职业性接触振动的男性中并非如此。作者得出结论,对每日职业性接触振动的男性进行的骨测量尺寸分析未能提供证据支持长期接触振动会导致掌骨加速骨质疏松这一假设。
