【摘要】 目的探讨天然河道游泳者不适症状及疾病发生的影响因素,为建立天然游泳场所卫生防护措施提供科学依据。方法于2006年采用整群抽样的方法对在广州某天然河道进行2次游泳的1601名游泳者采用填写自行编制的调查表和电话访问的形式调查游泳后和采取干预措施后(第2次游泳)游泳者不适症状的发生情况,并对其影响因素进行分析。结果第1次游泳后不适症状的发生率(17.9%,主要为眼部和皮肤症状)高于第2次(12.2%,主要为皮肤、眼部不适症状),差异有统计学意义(P=0.01);第1次游泳者眼部症状出现率(8.4%)高于第2次(5.O%),差异有统计学意义(P<0.05)。多因素 Logistic 回归分析显示,第1、2次游泳年龄、性别、在不洁河水中游泳且使用卫生棉条与不适症状的发生有关联(OR 值分别为0.95和0.97,3.55和2.32,14.83和6.7),与不适症状的发生有关联的其他因素还有水中游泳时间、游泳方式、是否呛水、呛水次数、戴耳塞、游泳头姿(OR 值分别为1.06,0.50,2.1,1.22,0.44,1.65)。结论在相对不洁的河水中游泳易发生不适症状,主要是眼部和皮肤症状,应注意个人卫生防护,并尽快建立天然游泳场所的卫生规范。更多还原
