There is concern that geohelminthiasis may adversely affect the growth and development of children. The relevance of this in the Caribbean is unclear since in many territories the prevalence of geohelminths is unknown. We report the results of three surveys conducted in Jamaican primary schools located in areas at high risk for geohelminthiasis. The first was conducted in 12 Kingston schools and comprised children in grades 2 to 5 (aged 7 to 10 years). The second and third surveys were conducted in rural areas with children in grades 2 to 5 and grades 4 and 5, respectively. Overall, 9244 children provided stool samples for analysis. The prevalence of Trichuris trichiura ranged from 42% to 47% among the surveys while that for Ascaris lumbricoides ranged from 15% to 37%. Children in grades 2 and 3 had lower T. trichiura prevalences than those in grades 4 and 5 in the first and second surveys (p < 0.05 and p < 0.005, respectively). In the second survey only, children in grades 2 and 3 had a lower prevalence of A. lumbricoides than those in grades 4 and 5 (p < 0.005). Most infections were light with approximately 1% of the sample having heavy egg densities.
人们担心土源性蠕虫病可能会对儿童的生长发育产生不利影响。由于许多地区土源性蠕虫的流行情况未知，所以其在加勒比地区的相关性尚不清楚。我们报告了在牙买加土源性蠕虫病高风险地区的小学进行的三项调查结果。第一次调查在金斯敦的12所学校进行，对象是二至五年级的学生（年龄7至10岁）。第二次和第三次调查分别在农村地区进行，对象分别是二至五年级和四至五年级的学生。总体而言，9244名儿童提供了粪便样本用于分析。在各项调查中，鞭虫的感染率在42%至47%之间，而蛔虫的感染率在15%至37%之间。在第一次和第二次调查中，二、三年级学生的鞭虫感染率低于四、五年级学生（分别为p < 0.05和p < 0.005）。仅在第二次调查中，二、三年级学生的蛔虫感染率低于四、五年级学生（p < 0.005）。大多数感染为轻度感染，样本中约1%的虫卵密度较高。
