We examined whether nutritional factors, including energy, protein, fat, and carbohydrate intake were associated with PSA in healthy men. &lt;b&gt;&lt;i&gt;Subjects and Methods:&lt;\/i&gt;&lt;\/b&gt; We investigated 13,594 men aged 50 years and over who visited a hospital for a routine health checkup between 2003 and 2007. Dietary intake was assessed using a food frequency questionnaire. We performed a multiple linear regression to examine the association between PSA and dietary intake. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; After controlling for age, body mass index, and physical activity, PSA was significantly negatively associated with percent protein intake (p for trend &lt; 0.001). Compared with the lowest quintile, PSA was 5.8% lower (95% CI: \u20138.9 to \u20132.5%) in the highest quintile. We also observed a significant positive association between percent fat intake and PSA concentration (p for trend 0.043). PSA was 3.4% greater (95% CI: 0\u20136.9%) among men in the highest quintile compared with those in the lowest quintile. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Men who had a lower percent protein intake and higher percent fat intake had an elevated PSA level, although the magnitude of these associations was small.<\/jats:p>","DOI":"10.1159\/000339601","type":"journal-article","created":{"date-parts":[[2012,7,10]],"date-time":"2012-07-10T11:39:18Z","timestamp":1341920358000},"page":"270-274","source":"Crossref","is-referenced-by-count":17,"title":["Relationship between Dietary Factors and Prostate-Specific Antigen in Healthy Men"],"prefix":"10.1159","volume":"89","author":[{"given":"Kazuhiro","family":"Ohwaki","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fumiyasu","family":"Endo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuko","family":"Kachi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazunori","family":"Hattori","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Osamu","family":"Muraishi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariko","family":"Nishikitani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eiji","family":"Yano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2012,7,10]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1002%2F%28SICI%291097-0215%2820000101%2985%3A1%3C60%3A%3AAID-IJC11%3E3.0.CO%3B2-B"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3109%2F02841869109092336"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1038%2Fbjc.1991.210"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1093%2Faje%2Fkwq148"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.3945%2Fajcn.2009.28474"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1200%2FJCO.2002.02.040"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00052775"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1002%2F%28SICI%291097-0215%2819961211%2968%3A6%3C716%3A%3AAID-IJC4%3E3.0.CO%3B2-6"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016%2FS0959-8049%2896%2900373-5"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1023%2FA%3A1008819500080"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007%2Fs10552-011-9789-5"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1158%2F1055-9965.EPI-08-0059"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1097%2F01.ju.0000169487.49018.73"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1002%2Fcncr.21603"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016%2FS0090-4295%2803%2900576-4"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093%2Fjnci%2F91.5.414"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1093%2Faje%2Fkwp280"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1097%2F00005392-200101000-00082"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016%2FS0022-5347%2805%2963944-4"}],"container-title":["Urologia Internationalis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/339601","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/339601","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T18:30:37Z","timestamp":1745433037000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000339601"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012]]},"references-count":19,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2012,10,1]]},"published-print":{"date-parts":[[2012,10,24]]}},"URL":"https:\/\/doi.org\/10.1159\/000339601","archive":["Portico"],"relation":{},"ISSN":["0042-1138","1423-0399"],"issn-type":[{"value":"0042-1138","type":"print"},{"value":"1423-0399","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012]]}}}
