There are currently no reports on the prevalence of STH infections among children in Koh Yao District of Phang Nga Province, Thailand. Therefore, this study aims to assess the prevalence of STH infections and associated risk factors among primary schoolchildren. A school\u2010based cross\u2010sectional study was conducted among 243 schoolchildren aged 7 to 12\u2009years from 12 rural primary schools across three subdistricts. Demographic data and associated risk factors were collected and analyzed. Stool samples were collected and examined for parasites using the formalin\u2010ethyl acetate sedimentation concentration and the modified Kato\u2010Katz methods. A multivariate logistic regression analysis was used to determine the strength of the relationship between risk variables and STH infections. Of the 243 participants (mean age: 8.99\u2009\u00b1\u20091.57\u2009years), 12 (4.94%, 95% CI: 2.60%\u20138.50%) were infected with STH. The most common STH infection was hookworm (4.11%), followed by\n                    <jats:italic>Trichuris trichiura<\/jats:italic>\n                    (1.65%). More than 80% (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200910, 83.33%) had a single intestinal parasite, while two (16.67%) were coinfected with two parasitic species. Infections were more prevalent among males (66.67%) compared to females (33.33%). Multiple regression analyses revealed that children above Grade 3 had a significantly higher prevalence of STH infections compared to those below Grade 3 (adjusted odds ratio [AOR]\u2009=\u200910.54; 95% CI: 1.24\u201389.14,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.031). Open defecation was also statistically associated with STH infections (AOR\u2009=\u200922.66; 95% CI: 1.18\u2013433.58,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.038). This study highlights a low prevalence of STH infections in the study area, with hookworm being the most common. The potential risk factors identified were linked to educational level and open defecation practices. Improving sanitation and enhancing health education to raise public awareness about hygiene are essential strategies for controlling STH infections among primary schoolchildren in remote areas.\n                  <\/jats:p>","DOI":"10.1155\/jotm\/2907585","type":"journal-article","created":{"date-parts":[[2025,7,25]],"date-time":"2025-07-25T04:15:03Z","timestamp":1753416903000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Soil\u2010Transmitted Helminth Infections and Associated Risk Factors Among Primary Schoolchildren in the Koh Yao Islands of Southern Thailand"],"prefix":"10.1155","volume":"2025","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2382-2333","authenticated-orcid":false,"given":"Nonthapan","family":"Phasuk","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4976-3274","authenticated-orcid":false,"given":"Prasit","family":"Na-Ek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6894-8955","authenticated-orcid":false,"given":"Udomsak","family":"Narkkul","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1196-6735","authenticated-orcid":false,"given":"Stephen J.","family":"Scholand","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4826-9474","authenticated-orcid":false,"given":"Chuchard","family":"Punsawad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,7,24]]},"reference":[{"key":"e_1_2_12_1_2","unstructured":"WHO: Neglected Tropical Diseases Further Neglected due to ODA Cuts 2025."},{"key":"e_1_2_12_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(06)68653-4"},{"key":"e_1_2_12_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.pt.2003.10.002"},{"key":"e_1_2_12_4_2","unstructured":"Cdc Soil-Transmitted Helminths 2025."},{"key":"e_1_2_12_5_2","unstructured":"WHO: Soil-Transmitted Helminth Infections 2025."},{"key":"e_1_2_12_6_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0137327"},{"key":"e_1_2_12_7_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0170174"},{"key":"e_1_2_12_8_2","doi-asserted-by":"publisher","DOI":"10.3347\/kjp.2013.51.6.727"},{"key":"e_1_2_12_9_2","first-page":"45","article-title":"The Prevalence of Intestinal Parasitic Infections Among Schoolchildren With Annual Anthelminthic Treatment in Narathiwat Province, Thailand","volume":"29","author":"Jiraamonninit C.","year":"2006","journal-title":"The Journal of Tropical Medicine and Parasitology"},{"key":"e_1_2_12_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1995-7645(13)60121-2"},{"key":"e_1_2_12_11_2","doi-asserted-by":"publisher","DOI":"10.4269\/ajtmh.2007.76.345"},{"key":"e_1_2_12_12_2","first-page":"218","article-title":"A Cross-Sectional Study of Intestinal Parasitic Infections Among Schoolchildren in Nan Province, Northern Thailand","volume":"33","author":"Waikagul J.","year":"2002","journal-title":"The Southeast Asian Journal of Tropical Medicine and Public Health"},{"key":"e_1_2_12_13_2","first-page":"83","article-title":"Intestinal Parasitic Infections Among School Children in Thailand","volume":"24","author":"Warunee N.","year":"2007","journal-title":"Tropical Biomedicine"},{"key":"e_1_2_12_14_2","first-page":"38","article-title":"Evaluation of Helminthiasis Control Program in Thailand at the End of the 8th Health Development Plan, 2001","volume":"26","author":"Jongsuksuntigul P.","year":"2003","journal-title":"The Journal of Tropical Medicine and Parasitology"},{"key":"e_1_2_12_15_2","doi-asserted-by":"publisher","DOI":"10.5372\/1905-7415.0806.357"},{"key":"e_1_2_12_16_2","first-page":"745","article-title":"Evaluation of Hookworm Control Program in Southern Thailand","volume":"25","author":"Chongsuvivatwong V.","year":"1994","journal-title":"The Southeast Asian Journal of Tropical Medicine and Public Health"},{"key":"e_1_2_12_17_2","first-page":"113","article-title":"School-Based Helminthiases Control: I.
