To investigate the prevalence of intestinal parasitic infestation among school-aged children residing in Vientiane capital city; and to assess the impact of its infestation on nutrition status of those children.
The school-based cross-sectional study was conducted from December 2005 to February 2006. The systemic random samplings were employed to select schools and schoolchildren. Five hundred and thirty-six schoolchildren (350 high-school children and 186 parents of elementary-school children) were completely interviewed by semistructured questionnaire and performed anthropometric measurement. The direct faecal smear was employed to analyse 299 (55.8%) stool samples. The SPSS version 12.01 and Epi Info version 6.0 were used for data analysis.
The overall prevalence of parasitic infestation was 38.1%, with 18.1% of Opisthorchis viverrini and 14.7% of Ascaris lumbricoides. The prevalences of stunting and underweight were 20.2% and 20.0%, respectively. The prevalences of stunting (OR = 3.28; P < 0.01) and underweight (OR = 2.69; P < 0.05) were higher among high-school children who were infested by intestinal parasites.
Approximately one-third of schoolchildren in Vientiane capital city were infested by intestinal parasites. The persistent parasitic infestation seemed to be associated with growth rate pattern among those children. School-based parasite control programme and health promotion are needed to eliminate this major public health problem in Lao People Democratic Republic.
调查居住在万象市的学龄儿童肠道寄生虫感染率；并评估寄生虫感染对这些儿童营养状况的影响。
于2005年12月至2006年2月进行了一项基于学校的横断面研究。采用系统随机抽样方法选择学校和学童。通过半结构化问卷对536名学童（350名高中生和186名小学生家长）进行了全面访谈，并进行了人体测量。采用直接粪便涂片法分析了299份（55.8%）粪便样本。使用SPSS 12.01版和Epi Info 6.0版进行数据分析。
寄生虫感染的总体患病率为38.1%，其中华支睾吸虫感染率为18.1%，蛔虫感染率为14.7%。发育迟缓率和体重不足率分别为20.2%和20.0%。肠道寄生虫感染的高中生中发育迟缓（OR = 3.28；P < 0.01）和体重不足（OR = 2.69；P < 0.05）的患病率更高。
万象市约三分之一的学龄儿童感染了肠道寄生虫。持续的寄生虫感染似乎与这些儿童的生长模式有关。需要开展基于学校的寄生虫控制项目和健康促进活动，以消除老挝人民民主共和国的这一主要公共卫生问题。
