BACKGROUND: Extremes of temperature are associated with short-term increases in daily mortality.
OBJECTIVES: We set out to identify subpopulations and mortality causes with increased susceptibility to temperature extremes.
METHODS: We conducted a case-only analysis using daily mortality and hourly weather data from 50 U.S. cities for the period 1989-2000, covering a total of 7,789,655 deaths. We used distributions of daily minimum and maximum temperature in each city to define extremely hot days ([greater than or equal to] 99th percentile) and extremely cold days ([less than or equal to] 1st percentile), respectively. For each (hypothesized) effect ...
