To examine the associations between shift work types and overweight/obesity among female nurses and midwives.
A cross-sectional study. Measurement included exposure variables: rotating shift work and night-only shift work; outcome variables: overweight and obesity; and potential confounding and associated variables: modifiable lifestyle factors, general health status, menopausal status, and work pattern.
Among the 2086 participants, almost 60% were overweight/obese (31.7% overweight; 27.1% obese). After we adjusted the selected confounders, we found that rotating shift workers were 1.02 times more likely to be overweight/obese than day workers (P = 0.007; 95% confidence interval [95% CI], 1.004 to 1.03; and P = 0.02; 95% CI: 1.004 to 1.04, respectively). Night-only shift work was found to be significantly associated with obesity only (P = 0.031; relative risk, 1.02; 95% CI, 1.002 to 1.04).
Rotating shift work was associated with both overweight and obesity; and night-only shift work was associated with obesity, not overweight.
研究轮班工作类型与女性护士和助产士超重/肥胖的相关性。
一项横断面研究。测量指标包括暴露变量：轮班工作和仅夜班工作；结果变量：超重和肥胖；以及潜在的混杂和相关变量：可改变的生活方式因素、总体健康状况、绝经状况和工作模式。
在 2086 名参与者中，近 60%超重/肥胖（31.7%超重；27.1%肥胖）。在调整了选定的混杂因素后，我们发现轮班工作者超重/肥胖的可能性比日班工作者高 1.02 倍（P = 0.007；95%置信区间[95%CI]，1.004 至 1.03；P = 0.02；95%CI：1.004 至 1.04）。仅夜班工作与肥胖显著相关（P = 0.031；相对风险，1.02；95%CI，1.002 至 1.04）。
轮班工作与超重和肥胖均相关；仅夜班工作与肥胖相关，与超重无关。
