We evaluated infection and risk factor data that were previously collected from 14,761 children aged 2\u201315 years during a large-scale program in northern Peru. We found that 1,124 of 14,761 children (7.61%) had <jats:italic>H. nana<\/jats:italic> infection, a likely underestimate given that only a single stool sample was examined by microscopy for diagnosis. The strongest association with infection was lack of adequate water (adjusted prevalence ratio [aPR] 2.22, 95% confidence interval [CI] 1.82\u20132.48) and sanitation infrastructure in the house (aPR 1.94, 95% CI 1.64\u20132.29). One quarter of those tested did not have a bathroom or latrine at home, which doubled their likelihood of infection. Similarly, one quarter did not have piped public water to the house, which also increased the likelihood of infection. Continued efforts to improve access to basic water and sanitation services will likely reduce the burden of infection in children for this and other intestinal infections.<\/jats:p>","DOI":"10.4269\/ajtmh.16-0939","type":"journal-article","created":{"date-parts":[[2017,6,6]],"date-time":"2017-06-06T07:00:48Z","timestamp":1496732448000},"page":"583-586","source":"Crossref","is-referenced-by-count":10,"title":["Prevalence, Age Profile, and Associated Risk Factors for Hymenolepis nana Infection in a Large Population-Based Study in Northern Peru"],"prefix":"10.4269","volume":"97","author":[{"given":"Percy M.","family":"Vilchez Barreto","sequence":"first","affiliation":[{"name":"Centro de Salud Global Tumbes, Universidad Peruana Cayetano Heredia, Lima, Per\u00fa;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo","family":"Gamboa","sequence":"additional","affiliation":[{"name":"Centro de Salud Global Tumbes, Universidad Peruana Cayetano Heredia, Lima, Per\u00fa;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Saul","family":"Santiva\u00f1ez","sequence":"additional","affiliation":[{"name":"Instituto Peruano de Parasitolog\u00eda Cl\u00ednica y Experimental, Lima, Per\u00fa;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seth E.","family":"O\u2019Neal","sequence":"additional","affiliation":[{"name":"Centro de Salud Global Tumbes, Universidad Peruana Cayetano Heredia, Lima, Per\u00fa;"},{"name":"School of Public Health, Oregon Health and Science University and Portland State University, Portland, Oregon;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Muro","sequence":"additional","affiliation":[{"name":"Centro de Salud Global Tumbes, Universidad Peruana Cayetano Heredia, Lima, Per\u00fa;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andr\u00e9s G.","family":"Lescano","sequence":"additional","affiliation":[{"name":"Emerge, Emerging Infections and Climate Change Research Unit, School of Public Health and Administration, Universidad Peruana Cayetano Heredia, Lima, Per\u00fa;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luz-Maria","family":"Moyano","sequence":"additional","affiliation":[{"name":"Centro de Salud Global Tumbes, Universidad Peruana Cayetano Heredia, Lima, Per\u00fa;"},{"name":"Epidemiology Unit, Hospital Regional, Tumbes, Peru;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillermo","family":"Gonz\u00e1lvez","sequence":"additional","affiliation":[{"name":"Enfermedades Transmisibles y An\u00e1lisis de Salud, Organizaci\u00f3n Panamericana de la Salud OPS\/OMS;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hector H.","family":"Garc\u00eda","sequence":"additional","affiliation":[{"name":"Centro de Salud Global Tumbes, Universidad Peruana Cayetano Heredia, Lima, Per\u00fa;"},{"name":"Department of Microbiology, School of Sciences, Universidad Peruana Cayetano Heredia, Lima, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"_","family":"_","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"2795","reference":[{"key":"ref1","series-title":"Parasitosis Intestinales por Cestodos y Trematodos.
