  1. Cold related mortalities and protection against cold in Yakutsk, eastern Siberia : observation and interview study.

    Article - En anglais

    Objective To assess how effectively measures adopted in extreme cold in Yakutsk control winter mortality.

    Design Interviews to assess outdoor clothing and measure indoor temperatures ; regressions of these and of delayed cause-specific mortalities on temperature.

    Setting Yakutsk, east Siberia, Russia

    Subjects :

    All people aged 50-59 and 65-74 years living within 400 km of Yakutsk during 1989-95 and sample of 1002 men and women who agreed to be interviewed.

    Main outcome measures Daily mortality from all causes and from ischaemic heart, cerebrovascular, and respiratory disease.

    Results Mean temperature for October-March 1989-95 was - 26.6°C. At 10.2°C people wore 3.30 (95% confidence interval 3.08 to 3.53) layers of clothing outdoors, increasing to 4.39 (4.13 to 4.66 ; P<0.0001) layers at - 20°C. Thick coats, often of fur, replaced anoraks as temperature fell to - 48.2°C. 82% of people went out each day when temperatures were 10.2°C to - 20°C, but below - 20°C the proportion fell steadily to 44% (35% to 53%) at - 48.2°C (P<0.001), and overall shivering outdoors did not increase.

    Living room temperature was 17.9 (17.2 to 18.5) °C at 10.2°C outdoors, 19.6 (18.8 to 20.4) °C at - 20°C, and 19.1 (18.6 to 19.6) °C at - 48.2°C. Mortality from all causes and from ischaemic heart and respiratory disease was unaffected by the fall in temperature.

    Mortality from respiratory disease (daily deaths per million) rose from 4.7 (4.3 to 5.1) to 5.1 (4.4 to 5.7) (P=0. (...)
