The aim of the current study is to investigate the association between cold temperatures and all-cause mortality, as well as cause-specific mortality, in Tallinn and Riga in North-Eastern Europe. Materials and Methods: We used daily information on deaths from state death registries and minimum temperatures from November to March over the period 1997\u20132015 in Tallinn and 2009\u20132015 in Riga. The relationship between the daily minimum temperature and mortality was investigated using the Poisson regression, combined with a distributed lag non-linear model considering lag times of up to 21 days. Results: We found significantly higher all-cause mortality owing to cold temperatures both in Tallinn (Relative Risk (RR) = 1.28, 95% Confidence Interval (CI) 1.01\u20131.62) and in Riga (RR = 1.41, 95% CI 1.11\u20131.79). In addition, significantly increased mortality due to cold temperatures was observed in the 75+ age group (RR = 1.64, 95% CI 1.17\u20132.31) and in cardiovascular mortality (RR = 1.83, 95% CI 1.31\u20132.55) in Tallinn and in the under 75 age group in Riga (RR = 1.58, 95% CI 1.12\u20132.22). In this study, we found no statistically significant relationship between mortality due to respiratory or external causes and cold days. The cold-related attributable fraction (AF) was 7.4% (95% CI -3.7\u201317.5) in Tallinn and 8.3% (95% CI -0.5\u201316.3) in Riga. This indicates that a relatively large proportion of deaths in cold periods can be related to cold in North-Eastern Europe, where winters are relatively harsh.<\/jats:p>","DOI":"10.3390\/medicina55080429","type":"journal-article","created":{"date-parts":[[2019,8,2]],"date-time":"2019-08-02T11:58:16Z","timestamp":1564747096000},"page":"429","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Mortality Related to Cold Temperatures in Two Capitals of the Baltics: Tallinn and Riga"],"prefix":"10.3390","volume":"55","author":[{"given":"Daniel Oudin","family":"\u00c5str\u00f6m","sequence":"first","affiliation":[{"name":"Division of Sustainable Health, Ume\u00e5 University, 901 87 Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Triin","family":"Veber","sequence":"additional","affiliation":[{"name":"Institute of Family Medicine and Public Health, University of Tartu, Ravila 19, 50411 Tartu, Estonia"},{"name":"Physiotherapy and Environmental Health Department, Tartu Health Care College, Nooruse 5, 50411 Tartu, Estonia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7009-1479","authenticated-orcid":false,"given":"\u017danna","family":"Martinsone","sequence":"additional","affiliation":[{"name":"Institute of Occupational Safety and Environmental Health, Riga Stradin\u0161 University, Dzirciema 16, LV-1007 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Darja","family":"Ka\u013cu\u017enaja","sequence":"additional","affiliation":[{"name":"Institute of Occupational Safety and Environmental Health, Riga Stradin\u0161 University, Dzirciema 16, LV-1007 Riga, Latvia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ene","family":"Indermitte","sequence":"additional","affiliation":[{"name":"Institute of Family Medicine and Public Health, University of Tartu, Ravila 19, 50411 Tartu, Estonia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Oudin","sequence":"additional","affiliation":[{"name":"Division of Sustainable Health, Ume\u00e5 University, 901 87 Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7965-9451","authenticated-orcid":false,"given":"Hans","family":"Orru","sequence":"additional","affiliation":[{"name":"Division of Sustainable Health, Ume\u00e5 University, 901 87 Ume\u00e5, Sweden"},{"name":"Institute of Family Medicine and Public Health, University of Tartu, Ravila 19, 50411 Tartu, Estonia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"087006","DOI":"10.1289\/EHP1026","article-title":"Heat Wave and Mortality: A Multicountry, Multicommunity Study","volume":"125","author":"Guo","year":"2017","journal-title":"Environ.
