The purpose of this study was to examine the associations between cardiopulmonary (CP) mortality and temperature in Canada. The recently developed statistical methodology was used. Mortality data (non-accidental death causes: CP and non-CP) recorded in 20 locations in Canada were used for the period of January 1, 1984 to December 31, 2007. Daily counts of deaths, temperature, and ozone levels were organized in the time-series data. Multivariate meta-analysis for non-linear multi-parameter associations was applied to estimate relative risk related to temperature exposure. Attributable mortalities related to heat and cold, with reference to optimum ambient temperature, associated with temperature were estimated by the locations. The study used the software elaborated in the R statistical language. The used statistical routines were developed by other authors. Attributable risks for temperature for CP mortality were estimated as: 7.6% (5.0, 9.6), 7.1% (4.6, 9.3), 0.5% (-0.1, 1.0) for global, cold and heat period, respectively.
