In light of recent and increasing incidences of pathogenic E. coli outbreaks at public bathing facilities attributable to non-toilet-trained infants and toddlers, many such facilities are restricting water contact for this age group. A number of manufacturers are now offering disposable "swim diapers," which claim to effectively retain fecal material under typical pool play conditions. The study reported here examined the solids retention effectiveness of three major brands of swim diapers as well as of conventional disposable diapers, under simulated water play conditions. Swim diapers of all three brands exhibited an approximately equal fine-solids retention capability of about 98 to 99 percent over 30 minutes of water immersion activity. Conventional disposable diapers invariably fell down or came apart during the experiments, resulting in very limited solids retention. This study indicates that commercially available swim diapers represent a vast improvement in reducing the potential for fecal material release in public pool facilities, but that some release will still generally occur with these products.
鉴于近期公共洗浴设施中因未接受如厕训练的婴幼儿引发的致病性大肠杆菌疫情不断增加，许多此类设施正在限制该年龄组的水上接触活动。现在有多家制造商提供一次性“游泳尿布”，声称在典型的泳池玩耍条件下能有效留住粪便物质。本文报道的这项研究在模拟水上玩耍条件下，检验了三个主要品牌游泳尿布以及传统一次性尿布的固体物保留效果。在30分钟的水浸活动中，所有三个品牌的游泳尿布都表现出大致相同的细固体物保留能力，约为98%至99%。传统一次性尿布在实验过程中总是掉落或散开，导致固体物保留能力非常有限。这项研究表明，市售游泳尿布在降低公共泳池设施中粪便物质释放可能性方面有了巨大改进，但这些产品通常仍会有一些粪便物质释放。
