Abstract

The mobility of five joint pairs ( metacarpophalangeal, wrist, elbow, knee and ankle) was investigated in 3,000 mixed school children of Bahia, Brazil. A sampling method was designed to assure an equal number of fifty children in the smallest classes, when age, race and sex were held constant. Race was classified in five subgroups to assess the proportion of Black admixture. Multiple regression was carried out to analyze the data. The results showed a consistent effect of age on decreasing joint mobility, The effect of race was also on decreasing mobility of wrist, elbow and ankle; the darker the child, the less the joint mobility. However, the effect of sex showed no general consistency; for wrist, elbow and knee the girls had more mobility than the boys; for the ankle the boys had more mobility than the girls; and the metacarpophalangeal joint there was no sex difference. The complexity of multicausal effects on joint mobility are discussed considering the simultaneous interplay of biological and environmental actions.

摘要

在巴西巴伊亚州的3000名混合学校儿童中，对五组关节（掌指关节、腕关节、肘关节、膝关节和踝关节）的活动度进行了调查。设计了一种抽样方法，以确保在年龄、种族和性别保持不变的情况下，最小班级中有50名儿童数量相等。种族被分为五个亚组，以评估黑人混血的比例。进行了多元回归分析数据。结果显示年龄对关节活动度下降有一致的影响，种族对腕关节、肘关节和踝关节活动度下降也有影响；孩子肤色越黑，关节活动度越低。然而，性别的影响没有普遍的一致性；对于腕关节、肘关节和膝关节，女孩的活动度比男孩大；对于踝关节，男孩的活动度比女孩大；而掌指关节没有性别差异。考虑到生物和环境作用的同时相互作用，讨论了对关节活动度多因果效应的复杂性。
