To examine whether shift work is a risk factor for low back pain (LBP) and the interaction effects of shift work and overweight/obesity on LBP over time among nurses.
A longitudinal study over 2 years. Measurements included reported LBP, shift work status, and selected potential confounders.
Among 928 LBP-free nurses at baseline, 319 (34.4%) developed LBP over 2 years. After adjusting for confounders, shift workers were 1.15 times more likely to develop LBP (adjusted odds ratio [aOR], 1.15; 95% confidence interval, 1.05 to 1.40; P = 0.03). The interaction analysis showed that overweight/obese shift workers were more likely to develop LBP than day workers (overweight: aOR, 1.23 vs aOR, 1.03, respectively; obesity: aOR, 1.34 vs aOR, 1.10, respectively).
Our findings suggest that shift workers are at a higher risk of developing LBP over time, especially those who are overweight/obese.
研究轮班工作是否是护士腰痛（LBP）的危险因素，以及轮班工作和超重/肥胖对 LBP 的交互作用随时间的变化。
一项为期 2 年的纵向研究。测量包括报告的 LBP、轮班工作状态和选定的潜在混杂因素。
在基线时无 LBP 的 928 名护士中，319 名（34.4%）在 2 年内出现 LBP。在调整混杂因素后，轮班工作者发生 LBP 的可能性是轮班工作者的 1.15 倍（调整后的优势比 [aOR]，1.15；95%置信区间，1.05 至 1.40；P = 0.03）。交互分析表明，超重/肥胖的轮班工作者比白班工作者更容易发生 LBP（超重：aOR，1.23 比 aOR，1.03；肥胖：aOR，1.34 比 aOR，1.10）。
我们的研究结果表明，轮班工作者随着时间的推移发生 LBP 的风险更高，尤其是那些超重/肥胖的人。
