Frostbite in reindeer herders

The aim of this study was to determine the prevalence of frostbite among reindeer herders and to clarify the co-factors that may relate to these injuries. 2081 (60%) male reindeer herders in Finland were asked information on frostbite. Logistic regression analysis was used for studying the effect of potential co-factors. 453 men (22% of the respondents) reported frostbites during the last twelve months, the areas most affected being the face, fingers and toes. The amount of time spent in snowmobile driving, white finger symptom and the area of reindeer herding proved to be significant explanatory factors. Since the majority of frostbites were associated with snowmobile driving in spite of protection and adaptation to cold, it seems that new technology has not solved all the problems of the working conditions in a cold environment.
