However, certain intestinal parasites remain problematic in some regions. This cross-sectional study was conducted between February and September 2016 in three suburban government primary schools (KK, BR, and HK), Saraburi, Thailand. Stool was collected from 263 asymptomatic subjects (4\u201315 years old), using simple direct smear, formalin\u2013ether concentration, Boeck and Drbohlav\u2019s Locke\u2013Egg\u2013Serum (LES) medium culture, and agar plate culture. A self-administered questionnaire was used to collect data about lifestyle and socioeconomic status. The overall rate of intestinal parasites was 22.1% (15.6% single infection and 6.5% multiple infections). The helminths involving the digestive system found were <jats:italic>Strongyloides stercoralis<\/jats:italic> (1.5%) and <jats:italic>Opisthorchis viverrini<\/jats:italic> (0.4%). For protozoan infection, the major cause was <jats:italic>Blastocystis hominis<\/jats:italic> (17.5%). The other protozoa included <jats:italic>Endolimax nana<\/jats:italic> (4.6%), <jats:italic>Entamoeba coli<\/jats:italic> (3.4%), <jats:italic>Entamoeba histolytica<\/jats:italic>\/<jats:italic>Entamoeba dispar<\/jats:italic> (1.1%), and <jats:italic>Giardia intestinalis<\/jats:italic> (0.8%). The sensitivity for the detection of <jats:italic>B. hominis<\/jats:italic> increased with the LES culture technique. The infection rate of each organism was not significantly different among the three schools except for <jats:italic>B. hominis<\/jats:italic> which showed the highest prevalence in the HK school (<jats:italic>P<\/jats:italic> = 0.001). This was correlated with the questionnaire results in which the HK school showed the highest risk of drinking contaminated water (<jats:italic>P<\/jats:italic> = 0.004). The present study emphasized the persistent problems of protozoan infections among suburban school-aged children. Lifestyle was still an important factor for intestinal parasitic infections among suburban school-aged Thai children in this study. Health education as well as routine surveillance was necessary to control the infections.<\/jats:p>","DOI":"10.4269\/ajtmh.17-0240","type":"journal-article","created":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T07:00:55Z","timestamp":1516690855000},"page":"763-767","source":"Crossref","is-referenced-by-count":20,"title":["A Cross-Sectional Study on Intestinal Parasitic Infections in Children in Suburban Public Primary Schools, Saraburi, the Central Region of Thailand"],"prefix":"10.4269","volume":"98","author":[{"given":"Buravej","family":"Assavapongpaiboon","sequence":"first","affiliation":[{"name":"Department of Parasitology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand;"},{"name":"King Chulalongkorn Memorial Hospital, Bangkok, Thailand;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Uthaitip","family":"Bunkasem","sequence":"additional","affiliation":[{"name":"Department of Parasitology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand;"},{"name":"King Chulalongkorn Memorial Hospital, Bangkok, Thailand;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vivornpun","family":"Sanprasert","sequence":"additional","affiliation":[{"name":"Department of Parasitology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand;"},{"name":"King Chulalongkorn Memorial Hospital, Bangkok, Thailand;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Surang","family":"Nuchprayoon","sequence":"additional","affiliation":[{"name":"Department of Parasitology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand;"},{"name":"King Chulalongkorn Memorial Hospital, Bangkok, Thailand;"},{"name":"Lymphatic Filariasis and Tropical Medicine Research Unit, Faculty of Medicine, Chulalongkorn Medical Research Center (Chula MRC), Chulalongkorn University, Bangkok, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","reference":[{"key":"b1","series-title":"Wkly Epidemiol Rec","first-page":"585","article-title":"Schistosomiasis and soil-transmitted helminthiases: number of people treated in 2015","volume":"91","author":"World Health Organization","year":"2016"},{"key":"b2","series-title":"Lancet","first-page":"1521","article-title":"Soil-transmitted helminth infections: ascariasis, trichuriasis, and hookworm","volume":"367","author":"Bethony","year":"2006"},{"key":"b3","series-title":"Asian Biomed","first-page":"779","article-title":"Brief communication (Original).
