目的了解深圳市居民重点食源性寄生虫感染现状及影响因素，为制定防治策略提供依据。方法采用随机分层抽样的方法，对全市各区的抽样点的居民进行华支睾吸虫、广州管圆线虫血清学检查和流行病学调查，华支睾吸虫血清学阳性者加做病原学检查。结果共检测血清1671份，总感染率为14．18％；男性感染率为17．00％，女性为10．94％；31-40岁人群感染率最高为19．71％，20岁以下年龄组最低为7．89％；个体私营人群感染率最高为20．25％，学生及儿童感染率最低为8．28％；初中文化程度人群感染率最高为18．17％，大专及以上文化程度最低为10．08％；不同性别、不同年龄组、不同职业和文化程度人群感染率差异均有统计学意义（P〈0．05）。危险因素Logistic分析表明：男性、文化程度较低、吃鱼生是食源性寄生虫感染的危险因素，而生熟砧板分开、饭前便后洗手及知晓寄生虫病健康危害为食源性寄生虫感染的保护性因素。结论深圳市居民食源性寄生虫感染有上升趋势，文化程度和饮食习惯是重要原因，要发挥现代传媒手段，大力倡导健康饮食行为。
