Heat stress in older individuals and patients with common chronic diseases

Figure 1: Relative risks (RRs) or odds ratios (ORs) for age and various health conditions. RRs compare hospital admission 9 or mortality 2^,18 during a heat wave with mortality (or hospital admission) observed during comparison dates without heat wave. ORs compare cases who died during a heat wave with controls in the same geographic area who did not die. Values greater than 1.0 indicate a greater risk of heat-related death or hospital admission. *95% confidence intervals (CIs) were not provided in this study. †Values were adjusted for sex and autonomy (ability to get out of bed, wash and use bathroom without help). ‡Values were adjusted for neighbourhood and age.

Figure 2: Relative risks (RRs) or odds ratios (ORs) for various social factors. RRs compare mortality during a heat wave with mortality during comparison dates without heat wave. ORs compare cases who died during a heat wave with controls in the same geographic area who did not die. Values greater than 1.0 indicate a greater risk of heat-related death. *Values were adjusted for neighbourhood and age. CI = confidence interval.
