As part of a longitudinal study of children, 941 mothers were asked to report on their childrens' swimming experiences and abilities. At age nine, twenty-nine per cent of the children could swim only a few strokes or not at all. A disproportionate number of children who could swim more than a few strokes came from high socio-economic backgrounds, from families where one or more of the parents could swim, and which scored higher on an index of active recreational orientation. There were no significant sex differences in swimming ability. There were 97 incidents reported where a child had been in difficulties while in water and had to be rescued. The importance of collecting data on such incidents is discussed.
作为一项针对儿童的纵向研究的一部分，941位母亲被要求汇报她们孩子的游泳经历和能力。在9岁时，29%的孩子只能游几下或者根本不会游泳。能游几下以上的孩子中，来自高社会经济背景、父母一方或多方会游泳以及在积极休闲倾向指数上得分较高的家庭的孩子比例过高。游泳能力方面没有显著的性别差异。报告了97起孩子在水中遇到困难并需要救援的事件。文中讨论了收集此类事件数据的重要性。
