Clearing snow from roofs causes serious injuries annually. The aim of this study was to describe injury mechanisms, injury panorama, and injury incidence in connection to this activity. A specific aim was to study the association between snow depth and injury incidence. A total of 95 people were injured during four study periods. The risk of injury is strongly associated with snow depth, and the incidence varied up to 10-fold between the studied winter seasons. The majority of injuries (91; 96%) occurred during leisure time and only four people were injured in the occupational setting. The most common injury mechanism was falling off roofs or ladders of residential homes. Nearly 60% sustained moderate or serious injuries (Maximum Abbreviated Injury Scale [MAIS] 2-3), and fractures accounted for almost half of all injuries. Because roofs of single-family homes in Sweden usually do not require snow removal for heavy snow loads, these injuries may have been both unnecessary and avoidable. Further education is required to advise the public on the risks associated with snow removal from roofs.
每年，清理屋顶积雪都会导致严重受伤。本研究旨在描述与该活动相关的受伤机制、受伤全貌及受伤发生率。一个具体目标是研究积雪深度与受伤发生率之间的关联。在四个研究时间段内，共有95人受伤。受伤风险与积雪深度密切相关，在所研究的冬季，发生率变化高达10倍。大多数受伤情况（91例；96%）发生在休闲时间，只有4人在工作环境中受伤。最常见的受伤机制是从住宅屋顶或梯子上跌落。近60%的人受中度或重伤（最高简略损伤量表[MAIS] 2 - 3级），骨折几乎占所有受伤情况的一半。由于瑞典独栋房屋的屋顶通常不需要为应对大雪负荷而除雪，这些伤害可能既不必要又可避免。需要开展进一步教育，向公众宣传与屋顶除雪相关的风险。
