【摘要】：目的了解河南省豫東地區(qū)腸道寄生蟲(chóng)感染的流行現(xiàn)狀,為該地區(qū)腸道寄生蟲(chóng)感染的防治提供科學(xué)依據(jù)。方法 2014年11月-2015年6月按照經(jīng)濟(jì)條件和地理方位進(jìn)行分層整群抽樣,隨機(jī)選擇豫東地區(qū)的臨潁縣、濮陽(yáng)縣、臺(tái)前縣、太康縣、西平縣、息縣、項(xiàng)城市、新鄭市、虞城縣等9個(gè)縣(市)26個(gè)調(diào)查點(diǎn),采集人群糞樣,采用改良加藤厚涂片法檢查腸道蠕蟲(chóng)感染情況,鉤蚴試管濾紙培養(yǎng)法鑒別鉤蟲(chóng)(Ancylostoma sp.)蟲(chóng)種,3~6歲兒童采用透明膠紙肛拭法檢查蟯蟲(chóng)(Enterobius vermicularis)感染情況,碘液染色法檢查腸道原蟲(chóng)感染情況。收集各調(diào)查點(diǎn)的主要飲用水源、農(nóng)民年人均純收入等基本信息。將不同地區(qū)感染率進(jìn)行標(biāo)準(zhǔn)化后進(jìn)行比較。不同蟲(chóng)種、性別、年齡和職業(yè)以及其他相關(guān)因素的感染率間差異比較采用卡方檢驗(yàn)。結(jié)果共收集糞樣6 696份,檢出腸道蠕蟲(chóng)6種,腸道原蟲(chóng)4種。腸道寄生蟲(chóng)總感染率為1.57%(105/6 696),其中腸道蠕蟲(chóng)和原蟲(chóng)感染率分別為0.91%(61/6 696)和0.66%(44/6 696)。感染率較高的3種腸道寄生蟲(chóng)分別為蟯蟲(chóng)(0.36%,24/6 696)、人芽囊原蟲(chóng)(Blastocystis hominis)(0.30%,20/6 696)和蛔蟲(chóng)(Ascaris lumbricoides)(0.19%,13/6 696)。3~6歲兒童蟯蟲(chóng)感染率為2.23%(15/674),其中肛拭蟯蟲(chóng)感染率為1.93%(13/674)。7份鉤蚴經(jīng)鑒定均為十二指腸鉤蟲(chóng)(Ancylostoma duodenale)。腸道寄生蟲(chóng)感染率較高的3個(gè)縣(市)分別是項(xiàng)城市(4.24%)、新鄭市(3.51%)和太康縣(3.34%)。男性和女性腸道寄生蟲(chóng)感染率分別為1.71%(55/3 214)和1.44%(50/3 482),兩者差異無(wú)統(tǒng)計(jì)學(xué)意義(χ~2=0.82,P0.05)。不同文化程度人群中,腸道寄生蟲(chóng)感染率最高的為高中/中專組2.11%(10/473),與其他組比校,差異無(wú)統(tǒng)計(jì)學(xué)意義(χ~2=2.41,P0.05)。不同年齡組人群中,15~29歲組人群的腸道寄生蟲(chóng)感染率最高,為2.38%(21/884),與其他年齡組比較,差異有統(tǒng)計(jì)學(xué)意義(χ~2=9.39,P0.01)。不同職業(yè)人群中,學(xué)齡前和學(xué)生人群的腸道寄生蟲(chóng)感染率較高,為2.5%(24/720)和2.09%(24/1 148),與其他職業(yè)人群比較,差異有統(tǒng)計(jì)學(xué)意義(χ~2=9.93,P0.05)。飲用水為井水的調(diào)查點(diǎn)人群腸道寄生蟲(chóng)感染率為1.21%(31/2 562),高于自來(lái)水飲用人群的0.65%(27/4 134)(χ~2=5.71,P0.05)。調(diào)查點(diǎn)農(nóng)民年人均純收入為1 200~11 600元,中位數(shù)為5 604.5元,腸道寄生蟲(chóng)感染率隨農(nóng)民年人均純收入的增加而降低(χ~2=11.08,P0.01)。結(jié)論河南省豫東地區(qū)人體重點(diǎn)寄生蟲(chóng)感染情況較前兩次調(diào)查有顯著下降,學(xué)齡前兒童、學(xué)生人群是今后監(jiān)測(cè)的重點(diǎn)人群。
[Abstract]:Objective to investigate the epidemic situation of intestinal parasite infection in eastern Henan Province, and to provide scientific basis for the prevention and treatment of intestinal parasite infection in this area. Methods from November 2014 to June 2015, 26 survey sites in 9 counties (cities), such as Linying County, Puyang County, Taiqian County, Taikang County, Xiping County, Xixian County, Xiangcheng City, Xinzheng City and Yucheng County, were randomly selected according to economic conditions and geographical location. The fecal samples were collected and the intestinal worm infection was examined by modified Kato thick smear method. Identification of hookworm (Ancylostoma sp.) by in vitro filter paper culture of hookworm The infection of Enterobius vermicularis (Enterobius vermicularis) was detected by transparent adhesive paper anal swabs in children aged 3 years and 6 years old, and the infection of Enterobius vermicularis was detected by iodine staining. Collect the main drinking water sources, farmers' annual per capita net income and other basic information. The infection rate in different areas was compared after standardization. Chi-square test was used to compare the infection rate among different species, sex, age, occupation and other related factors. Results A total of 6696 fecal samples were collected and 6 species of intestinal worms and 4 species of intestinal protozoa were detected. The total infection rate of intestinal parasites was 1.57% (105 脳 6696). The infection rates of intestinal worms and protozoa were 0.91% (61 鈮，
