We conducted a nested case\u2013control study of French AREVA NC Pierrelatte nuclear workers employed between 1960 and 2005 to estimate CSD risks adjusting for major CSD risk factors (smoking, blood pressure, body mass index, total cholesterol and glycaemia) and external \u03b3-radiation dose.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>The study included 102 cases of death from CSD and 416 controls individually matched on age, gender, birth cohort and socio-professional status. Information on CSD risk factors was collected from occupational medical records. Organ-specific absorbed doses were estimated using biomonitoring data, taking into account exposure regime and uranium physicochemical properties. External \u03b3-radiation was measured by individual dosimeter badges. Analysis was conducted with conditional logistic regression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Workers were exposed to very low radiation doses (mean \u03b3-radiation dose 2\u2009and lung uranium dose 1\u2009mGy). A positive but imprecise association was observed (excess OR per mGy 0.2, 95% CI 0.004\u2009to 0.5). Results obtained after adjustment suggest that uranium exposure might be an independent CSD risk factor.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our results suggest that a positive association might exist between internal uranium exposure and CSD mortality, not confounded by CSD risk factors. Future work should focus on numerous uncertainties associated with internal uranium dose estimation and on understanding biological pathway of CSD after protracted low-dose internal radiation exposure.<\/jats:p><\/jats:sec>","DOI":"10.1136\/oemed-2017-104575","type":"journal-article","created":{"date-parts":[[2017,10,31]],"date-time":"2017-10-31T16:16:54Z","timestamp":1509466614000},"page":"270-276","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":33,"title":["Circulatory disease in French nuclear fuel cycle workers chronically exposed to uranium: a nested case\u2013control study"],"prefix":"10.1136","volume":"75","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5815-4980","authenticated-orcid":false,"given":"Sergey","family":"Zhivin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irina","family":"Guseva Canu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Estelle","family":"Davesne","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Blanchardon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e9r\u00f4me-Philippe","family":"Garsi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Samson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine","family":"Niogret","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lydia B","family":"Zablotska","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominique","family":"Laurier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2017,10,31]]},"reference":[{"key":"2020050723003772000_75.4.270.1","unstructured":"WHO (World Health Organization).
