Association between high temperature and mortality of Warsaw inhabitants, 2008-2013 / Zwiazek umieralnosci mieszkanców Warszawy z wysoka temperatura powietrza, w latach 2008-2013

Different aspects of association between daily maximum temperature and daily number of deaths from all causes (excluding external) in Warsaw in periods of warm months (May - September) in years 2008-2013 were analysed. Analysis of dependence between temperature and mortality for whole population as well as for subpopulations with respect to sex and age demonstrated its similar U-shape. For each subpopulation a value of temperature at which dependence of mortality from temperature is changing its character from decreasing to increasing, interpreted as comfort conditions, was computed. Its value varied between 20 and 24oC with slight tendency to be higher for woman. Heat waves defined as at least three consecutive days with maximal temperature higher than 30oC have additional (to temperature effect itself ) effect on male mortality however, only in males aged 70 years and more the effect was statistically significant.
