To assess the point prevalence of intestinal parasites and their association with nutritional parameters.
Anganwadi centers under the Integrated Child Development Scheme (ICDS) in Lucknow, North India.
Cross-sectional survey.
By random draw, 32 out of 153 Anganwadi centers were selected. All eligible subjects registered with the Anganwadi worker were enrolled. These were 1061 children (48.3% girls and 51.7% boys) between the ages of 1.5 to 3.5 years.
Of these, 67.6% were underweight (weight for age < -2 SD), 62.8% were stunted (height for age < -2 SD) and 26.5% were wasted (weight for height < -2 SD). Parasites were detected in 17.5% (95% CI 15.3%-19.9%) children by a single direct fecal smear examination. Of these, Ascaris lumbricoides was found in 124 (68.1%) and Giardia lamblia in 60 (32.9%). There was no association between weight or height and parasite positivity. The mean hemoglobin levels for children who were smear positive versus smear negative for ascaris or giardia were 9.1 g/dl and 9.6 g/dl, respectively (p < 0.0001).
In the urban slums the point prevalence of intestinal parasites is 17.5% in the preschool children. Malnutrition and low hemoglobin levels are also widely prevalent. Urgent remedial steps are needed on community basis to improve their nutritional status and control parasitic infestation.
评估肠道寄生虫的现患率及其与营养参数的关联。
印度北部勒克瑙综合儿童发展服务计划（ICDS）下的安格瓦迪中心。
横断面调查。
通过随机抽取，从153个安格瓦迪中心中选取32个。纳入所有在安格瓦迪工作人员处登记的符合条件的受试者。这些受试者为1061名年龄在1.5至3.5岁之间的儿童（48.3%为女孩，51.7%为男孩）。
其中，67.6%体重不足（年龄别体重＜-2标准差），62.8%发育迟缓（年龄别身高＜-2标准差），26.5%消瘦（身高别体重＜-2标准差）。通过单次直接粪便涂片检查，在17.5%（95%置信区间15.3%-19.9%）的儿童中检测到寄生虫。其中，蛔虫感染124例（68.1%），贾第虫感染60例（32.9%）。体重或身高与寄生虫阳性之间无关联。蛔虫或贾第虫涂片阳性儿童与涂片阴性儿童的平均血红蛋白水平分别为9.1g/dl和9.6g/dl（p＜0.0001）。
在城市贫民窟，学龄前儿童肠道寄生虫的现患率为17.5%。营养不良和低血红蛋白水平也广泛存在。需要在社区层面采取紧急补救措施，以改善他们的营养状况并控制寄生虫感染。
