The prevalence of intestinal parasites infection in institutions for mental retardation of Urmia City, West Azerbaijan Province, Iran was investigated.
This descriptive - cross sectional study was carried out in institutions of mentally retarded patients of Urmia city in 2007-2008. Fecal samples of 225 less than 29 year old mentally disabled individuals were examined using direct smear, formalin - ether concentration. Beside their scotch tape samples were observed for Enterobius eggs. Statistical evaluation was performed by SPSS 10.
Of 225 mentally retarded persons, 118(52.4%) and 107(47.6%) were female and male. The overall prevalence of infection was 20.4% and that of male, and female were 20.5% and 20.3%, respectively. 17.3% of examined individuals had protozoa infection and 3.1% showed Enterobius vermicularis eggs. The infection rates of detected intestinal protozoa were Entamoeba coli 9.7%, Giardia lamblia 6.2%, Iodoamoeba butschlii 5.7%, Blastocystis hominis 4%, and Entamoeba histolytica/dispar 0.4%. Forty percent of 1-5 year, 22.8% of 6-14 year, 22.2% of 15-18 year, and 16.8% of more than 18-year age groups, had positive results in their tests. According to IQ test results, 23.8% of less than 25 score group, 19.6% of 25-50, 17.2% of 50-75, and 40% of 75-90 groups were infected.
More efforts for increasing sanitation level and prompt diagnosis and treatment of infected persons in these institutions are necessary.
对伊朗西阿塞拜疆省乌尔米耶市智障机构中肠道寄生虫感染的患病率进行了调查。
2007 - 2008年在乌尔米耶市智障患者机构开展了这项描述性横断面研究。对225名年龄小于29岁的智障个体的粪便样本采用直接涂片法、福尔马林 - 乙醚浓缩法进行检测。此外，观察其透明胶带样本中是否有蛲虫卵。使用SPSS 10进行统计评估。
225名智障者中，女性118名（52.4%），男性107名（47.6%）。总体感染患病率为20.4%，男性和女性的感染患病率分别为20.5%和20.3%。17.3%的受检个体有原生动物感染，3.1%的个体粪便中发现蛲虫卵。检测到的肠道原生动物感染率分别为：结肠内阿米巴9.7%、蓝氏贾第鞭毛虫6.2%、布氏嗜碘阿米巴5.7%、人芽囊原虫4%、溶组织内阿米巴/迪斯帕内阿米巴0.4%。1 - 5岁年龄组40%、6 - 14岁年龄组22.8%、15 - 18岁年龄组22.2%、18岁以上年龄组16.8%检测结果呈阳性。根据智商测试结果，智商得分低于25分的组中有23.8%被感染，25 - 50分的组中有19.6%被感染，50 - 75分的组中有17.2%被感染，75 - 90分的组中有40%被感染。
有必要在这些机构中做出更多努力来提高卫生水平，并及时诊断和治疗感染者。
