This cross-sectional survey describes the prevalence of soil-transmitted helminths and intestinal protozoa in preschool children 0\u20135 years of age in seven communities in the Amhara region of Ethiopia, and investigates associations between infection, household water and sanitation characteristics, and child growth. Stool samples were collected from children 0\u20135 years of age, 1 g of sample was preserved in sodium acetate\u2013acetic acid\u2013formalin, and examined for intestinal helminth eggs and protozoa cysts ether-concentration method. A total of 212 samples were collected from 255 randomly selected children. The prevalence of <jats:italic>Ascaris lumbricoides<\/jats:italic>, <jats:italic>Trichuris trichiura<\/jats:italic>, and hookworm were 10.8% (95% confidence interval [CI] 6.6\u201315.1), 1.4% (95% CI = 0\u20133.0), and 0% (95% CI = 0\u20131.7), respectively. The prevalence of the pathogenic intestinal protozoa <jats:italic>Giardia lamblia<\/jats:italic> and <jats:italic>Entamoeba histolytica<\/jats:italic>\/<jats:italic>dispar<\/jats:italic> were 10.4% (95% CI = 6.2\u201314.6) and 3.3% (95% CI = 0.09\u20135.7), respectively. Children with <jats:italic>A. lumbricoides<\/jats:italic> infections had lower height-for-age <jats:italic>z<\/jats:italic>-scores compared with those without, but were not more likely to have stunting. Compared with those without <jats:italic>G. lamblia<\/jats:italic>, children with <jats:italic>G. lamblia<\/jats:italic> infections had lower weight-for-age and weight-for-height <jats:italic>z<\/jats:italic>-scores and were more than five times as likely to meet the <jats:italic>z<\/jats:italic>-score definition for wasting (prevalence ratio = 5.42, 95% CI = 2.97\u20139.89). This article adds to a growing body of research on child growth and intestinal parasitic infections and has implications for their treatment and prevention in preschool-aged children.<\/jats:p>","DOI":"10.4269\/ajtmh.16-0800","type":"journal-article","created":{"date-parts":[[2017,2,7]],"date-time":"2017-02-07T02:05:25Z","timestamp":1486433125000},"page":"866-872","source":"Crossref","is-referenced-by-count":29,"title":["Epidemiology of Soil-Transmitted Helminth and Intestinal Protozoan Infections in Preschool-Aged Children in the Amhara Region of Ethiopia"],"prefix":"10.4269","volume":"96","author":[{"given":"Kristen","family":"Aiemjoy","sequence":"first","affiliation":[{"name":"Proctor Foundation, University of California San Francisco, San Francisco, California."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sintayehu","family":"Gebresillasie","sequence":"additional","affiliation":[{"name":"The Carter Center, Atlanta, Georgia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicole E.","family":"Stoller","sequence":"additional","affiliation":[{"name":"Proctor Foundation, University of California San Francisco, San Francisco, California."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayalew","family":"Shiferaw","sequence":"additional","affiliation":[{"name":"The Carter Center, Atlanta, Georgia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zerihun","family":"Tadesse","sequence":"additional","affiliation":[{"name":"The Carter Center, Atlanta, Georgia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melsew","family":"Chanyalew","sequence":"additional","affiliation":[{"name":"Amhara Regional Health Bureau, Bahir-Dar, Ethiopia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Solomon","family":"Aragie","sequence":"additional","affiliation":[{"name":"The Carter Center, Atlanta, Georgia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelly","family":"Callahan","sequence":"additional","affiliation":[{"name":"The Carter Center, Atlanta, Georgia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeremy D.","family":"Keenan","sequence":"additional","affiliation":[{"name":"Proctor Foundation, University of California San Francisco, San Francisco, California."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","reference":[{"key":"ref1","series-title":"Soil-Transmitted Helminth Infections Fact Sheet","author":"World Health Organization","year":"2016"},{"key":"ref2","series-title":"Manson's Tropical Diseases","article-title":"Intestinal protozoa","author":"Kelly","year":"2014"},{"key":"ref3","series-title":"Am Jf Health Res","first-page":"170","article-title":"Status of soil-transmitted helminths infection in Ethiopia","volume":"3","author":"Fikresilasie","year":"2015"},{"key":"ref4","series-title":"J Infect Dev Ctries","first-page":"253","article-title":"Epidemiology of soil-transmitted helminths, Schistosoma mansoni, and haematocrit values among schoolchildren in Ethiopia","volume":"7","author":"Abera","year":"2013"},{"key":"ref5","series-title":"Trans R Soc Trop Med Hyg","first-page":"213","article-title":"Potential for integrated control of neglected tropical diseases in Ethiopia","volume":"102","author":"Tadesse","year":"2008"},{"key":"ref6","series-title":"J Parasitol Res","first-page":"4737891","article-title":"Soil-transmitted helminth reinfection and associated risk factors among school-age children in Chencha District, southern Ethiopia: a cross-sectional study","volume":"2016","author":"Zerdo","year":"2016"},{"key":"ref7","series-title":"PLoS Negl Trop Dis","first-page":"e2223","article-title":"Intestinal parasite prevalence in an area of Ethiopia after implementing the SAFE strategy, enhanced outreach services, and health extension program","volume":"7","author":"King","year":"2013"},{"key":"ref8","series-title":"Pediatrics","first-page":"e473","article-title":"Worldwide timing of growth faltering: revisiting implications for interventions","volume":"125","author":"Victora","year":"2010"},{"key":"ref9","series-title":"Lancet","first-page":"143","article-title":"Comparison of annual versus twice-yearly mass azithromycin treatment for hyperendemic trachoma in Ethiopia: a cluster-randomised trial","volume":"379","author":"Gebre","year":"2012"},{"key":"ref10","series-title":"PLoS Negl Trop Dis","first-page":"e0005099","article-title":"\u2018If an eye is washed properly, it means it would see clearly\u2019: a mixed methods study of face washing knowledge, attitudes, and behaviors in rural Ethiopia","volume":"10","author":"Aiemjoy","year":"2016"},{"key":"ref11","series-title":"Am J Trop Med Hyg","first-page":"65","article-title":"Is using a latrine \u201ca strange thing to do\u201d?
