Abstract

To date, no study has investigated the effects of avalanches on survivor's health beyond the first years. The aim of this study was to examine long-term health status 16 years after exposure to avalanches using a matched cohort design. Mental health, sleep quality and somatic symptoms among avalanche survivors (n= 286) and non-exposed controls (n= 357) were examined. Results showed that 16% of survivors currently experience avalanche-specific PTSD symptoms (PDS score. >. 14). In addition, survivors presented with increased risk of PTSD hyperarousal symptoms (>85th percentile) (aRR. = 1.83; 98.3% CI [1.23-2.74]); sleep-related problems (PSQI score. >. 5) (aRR. = 1.34; 95% CI [1.05-1.70]); PTSD-related sleep disturbances (PSQI-A score. ≥. 4) (aRR. = 1.86; 95% CI [1.30-2.67]); musculoskeletal and nervous system problems (aRR 1.43; 99% CI 1.06-1.93) and gastrointestinal problems (aRR 2.16; 99% CI 1.21-3.86) compared to the unexposed group. Results highlight the need for treatment for long-term PTSD symptoms and sleep disruption in disaster communities.
