It is hypothesized that excess weight is a risk factor for delayed recovery from neck pain, such as from whiplash injuries. However, the association between obesity and recovery from whiplash injury has not been studied. The authors examined the association between body mass index and time to recovery from whiplash injuries in a population-based cohort study of traffic injuries in Saskatchewan, Canada. The cohort included 4,395 individuals who made an insurance claim to Saskatchewan Government Insurance and were treated for whiplash injury between July 1, 1994, and December 31, 1995. Of those, 87.7% had recovered by November 1, 1997. No association was found between baseline body mass index and time to recovery. Compared with individuals with normal weight, those who were underweight (hazard rate ratio = 0.88, 95% confidence interval: 0.73, 1.06), overweight (hazard rate ratio = 1.01, 95% confidence interval: 0.94, 1.09), and obese (hazard rate ratio = 0.99, 95% confidence interval: 0.90, 1.08) had similar rates of recovery, even after adjustment for other factors. The results do not support the hypothesis that individuals who are overweight or obese have a worse prognosis for whiplash.
据推测，超重是颈部疼痛（如挥鞭样损伤所致疼痛）延迟恢复的一个风险因素。然而，肥胖与挥鞭样损伤恢复之间的关联尚未得到研究。作者在加拿大萨斯喀彻温省一项基于人群的交通伤队列研究中，检验了体重指数与挥鞭样损伤恢复时间之间的关联。该队列包括4395名向萨斯喀彻温省政府保险机构提出保险索赔并在1994年7月1日至1995年12月31日期间接受挥鞭样损伤治疗的个体。其中，87.7%的人在1997年11月1日前已康复。未发现基线体重指数与恢复时间之间存在关联。与体重正常的个体相比，体重过轻（风险率比=0.88，95%置信区间：0.73，1.06）、超重（风险率比=1.01，95%置信区间：0.94，1.09）和肥胖（风险率比=0.99，95%置信区间：0.90，1.08）的个体恢复率相似，即使在对其他因素进行调整后也是如此。这些结果不支持超重或肥胖个体挥鞭样损伤预后较差这一假设。
