目的：为了评估太阳能照射的有效性和可接受性，在5岁以下的儿童，在城市贫民窟在韦洛雷，泰米尔纳德邦。方法：共100名儿童被分配到接受饮用水已受到太阳能消毒聚对苯二甲酸乙二醇酯瓶。还选择了100名年龄和性别匹配的对照。两组受试者均接受为期6个月的每周家访，以检查是否有任何腹泻发病。在随访期结束时，干预的可接受性进行了评估，通过访谈，问卷调查，和焦点小组discussions.Results：有显着减少的发病率，持续时间和严重程度腹泻的儿童接受太阳能消毒水，尽管86%的儿童饮用水以外的治疗干预。干预组的腹泻发病率为1.7/儿童年，对照组为2.7/儿童年，发病率比为0.64（95% CI -0.48至0.86）。通过使用太阳能消毒，腹泻的风险降低了40%。在定性评价的可接受性，大多数妇女认为，太阳能消毒是一个可行的和可持续的方法disinfectingwater.Conclusions：太阳能消毒水是一种廉价的，有效的，和可接受的方法，增加水安全在资源有限的环境中，并能显着降低儿童腹泻发病率。
Aims: To evaluate the efficacy and acceptability of solar irradiation in the prevention of diarrhoeal morbidity in children under 5 years of age, in an urban slum in Vellore, Tamil Nadu.Methods: A total of 100 children were assigned to receive drinking water that had been subjected to solar disinfection in polyethylene terephthalate bottles. One hundred age and sex matched controls were also selected. Both groups were followed by weekly home visits for a period of six months for any diarrhoeal morbidity. At the end of the follow up period, the acceptability of the intervention was assessed by interviews, questionnaires, and focus group discussions.Results: There was significant reduction in the incidence, duration, and severity of diarrhoea in children receiving solar disinfected water, despite 86% of the children drinking water other than that treated by the intervention. The incidence of diarrhoea in the intervention group was 1.7 per child-year, and among controls 2.7 per child-year, with an incidence rate ratio of 0.64 (95% CI -0.48 to 0.86). The risk of diarrhoea was reduced by 40% by using solar disinfection. In qualitative evaluation of acceptability, most women felt that solar disinfection was a feasible and sustainable method of disinfecting water.Conclusions: Solar disinfection of water is an inexpensive, effective, and acceptable method of increasing water safety in a resource limited environment, and can significantly decrease diarrhoeal morbidity in children.
