The questionnaire included age, sex, duration of decontamination work, previous occupation, education provided by employers regarding heat illness, preventive action against heat illness, and subjective symptoms of heat illness during work. We included 528 men, who replied and answered all questions, in the statistical analysis. Subjective symptoms of heat illness were categorized as \u201cno symptoms\u201d, \u201cGrade I\u201d and \u201cGrade II\u201d according to severity. A multiple linear regression model was used to determine the factors associated with the severity of heat illness.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean age of the subjects was 47.6 years old (standard deviation: 13.4). Of the 528 workers, 316 (59.8%) experienced heat illness symptoms (213 at Grade I and 103 at Grade II). The results of the stepwise selection revealed that age, outdoor manual labor, adequate sleep, use of a cool vest, and salt intake were selected as preventive factors, whereas living in a company dormitory or temporary housing, wearing light clothing, and consuming breakfast were selected as risk factors for heat illness.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Both working conditions and living environment are associated with heat illness in radiation decontamination workers. Type of housing and sleep are also strongly related to heat illness during work. Employers should consider not only the working conditions of the employee but also the employee's daily living conditions, in order to prevent heat illness.<\/jats:p><\/jats:sec>","DOI":"10.1539\/joh.14-0218-oa","type":"journal-article","created":{"date-parts":[[2015,4,16]],"date-time":"2015-04-16T22:03:36Z","timestamp":1429221816000},"page":"331-338","source":"Crossref","is-referenced-by-count":23,"title":["Risk and preventive factors for heat illness in radiation decontamination workers after the Fukushima Daiichi Nuclear Power Plant accident"],"prefix":"10.1093","volume":"57","author":[{"given":"Takeyasu","family":"Kakamu","sequence":"first","affiliation":[{"name":"Department of Hygiene and Preventive Medicine Fukushima Medical University School of Medicine Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoo","family":"Hidaka","sequence":"additional","affiliation":[{"name":"Department of Hygiene and Preventive Medicine Fukushima Medical University School of Medicine Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takehito","family":"Hayakawa","sequence":"additional","affiliation":[{"name":"Department of Hygiene and Preventive Medicine Fukushima Medical University School of Medicine Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomohiro","family":"Kumagai","sequence":"additional","affiliation":[{"name":"Department of Hygiene and Preventive Medicine Fukushima Medical University School of Medicine Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takanobu","family":"Jinnouchi","sequence":"additional","affiliation":[{"name":"Department of Hygiene and Preventive Medicine Fukushima Medical University School of Medicine Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayoshi","family":"Tsuji","sequence":"additional","affiliation":[{"name":"Department of Hygiene and Preventive Medicine Fukushima Medical University School of Medicine Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shinichi","family":"Nakano","sequence":"additional","affiliation":[{"name":"Nakano Hospital Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kikuo","family":"Koyama","sequence":"additional","affiliation":[{"name":"Fukushima Occupational Health Promotion Center Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuhito","family":"Fukushima","sequence":"additional","affiliation":[{"name":"Department of Hygiene and Preventive Medicine Fukushima Medical University School of Medicine Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2015,10,31]]},"reference":[{"key":"e_1_2_1_2_1","unstructured":"Prime Minister of Japan and his Cabinet.Information related to Fukushima nuclear power plant and radioactivity.
