To assess the effect of body mass index (BMI) on pain and function outcomes in the acute and subacute stages of work-related low back pain (LBP).
A prospective cohort of working-age patients (410 male, 197 female) with recent onset LBP (≤14 days' duration) provided height and weight as part of a study of prognostic factors for back disability. Self-reported pain, functional limitation, and work status were assessed at 1- and 3-month follow-ups.
BMI (kg/m) was used to categorize participants as normal (31%), overweight (40%), or obese (29%). In prediction analyses, outcomes of pain, functional limitation, and return to work showed no significant variation (P > 0.05) by BMI, with or without controlling for potential confounds.
BMI is not a useful prognostic factor during the acute and subacute stages of work-related LBP.
评估体重指数 (BMI) 对工作相关腰痛 (LBP) 急性和亚急性期疼痛和功能结果的影响。
一项针对工作年龄段患者（410 名男性，197 名女性）的前瞻性队列研究，这些患者最近出现腰痛（持续时间≤14 天），并作为背部残疾预后因素研究的一部分提供了身高和体重数据。在 1 个月和 3 个月的随访中，评估了自我报告的疼痛、功能受限和工作状况。
BMI（kg/m）用于将参与者分为正常（31%）、超重（40%）或肥胖（29%）。在预测分析中，疼痛、功能受限和重返工作岗位的结果在 BMI 方面没有显著差异（P > 0.05），无论是否控制潜在混杂因素。
BMI 不是工作相关 LBP 急性和亚急性期的有用预后因素。
