Assessing the threshold temperatures among different age and cause-of-deaths

摘要: The relationship between temperature and mortality is non-linear the effect estimates depend on threshold temperatures selected. However, little known about whether differ with age or cause of deaths in Southern Hemisphere. We conducted polynomial distributed lag models to assess for from all ages (Dall), aged 15 64 (D15-64), 65- 84(D65-84), ≥85 years (D85+), respiratory (RD) cardiovascular diseases (CVD) Brisbane, Australia, 1996–2004. examined both hot cold thresholds, lags up days effects 3 effects. Results show that current day, was 20°C 28°C groups Dall, D15-64 D85+. higher (23°C) group D65-84 lower (21°C) CVD. (29°C) (27°C) RD. Compared 15-day lags, D15-64, thresholds were D65-84, D85+, RD CVD; while 3-day Temperature appeared death categories. elderly CVD more sensitive stress than adult group. These findings may have implications assessment temperature-related development weather/health warning systems.
