The relationship between a healthy lifestyle and depression in radiology residents remains poorly understood. This study aims to investigate the relationship between a healthy lifestyle and depressive symptoms in radiology residents in a nationwide survey.
Cross-sectional study.
The survey was conducted among radiology residents undergoing training in China between December 2020 and April 2021. This encompassed a total of 215 municipalities and 406 training centres.
3677 radiology residents in 31 provinces of China.
The primary outcome was Healthy Lifestyle Score (HLS). A multiple logistic regression analysis was performed to evaluate the association between lifestyle factors and depressive symptoms. Additionally, the weighted quantile sum (WQS) index was utilised to identify the lifestyle factor that had the greatest impact on depressive symptoms.
The study sample consisted of 3677 participants, among whom the prevalence of depression was 34.7%. Participants were categorised based on their Health Lifestyle Score (HLS) into three groups: low HLS (LHLS), moderate HLS (MHLS) and high HLS (HHLS), with proportions of 8.0%, 79.8% and 12.2%, respectively. Those with LHLS were found to have a significantly higher risk of depression (OR: 5.21, 95% CI: 3.72 to 7.30) and a more severe level of depression (p for trend<0.001) compared with those with HHLS. Furthermore, the Well-being Quality of Life Index (WQS) showed a significant association with depression (OR: 0.34, 95% CI: 0.28 to 0.40), with sleep being identified as the most significant factor contributing to a healthy lifestyle.
The study establishes a significant association between an LHLS (long and irregular work hours) and an elevated risk of depressive symptoms among the participants, emphasising the crucial role of sleep in this relationship. These findings underline the importance of promoting a healthy lifestyle, specifically emphasising the need for adequate sleep, among radiology residents.
健康的生活方式与放射科住院医师抑郁之间的关系仍知之甚少。本研究旨在通过全国范围内的调查，研究放射科住院医师健康生活方式与抑郁症状之间的关系。
横断面研究。
该调查于 2020 年 12 月至 2021 年 4 月期间在中国接受培训的放射科住院医师中进行。这涵盖了全国 215 个市和 406 个培训中心。
中国 31 个省的 3677 名放射科住院医师。
主要结果是健康生活方式评分（HLS）。进行了多因素逻辑回归分析，以评估生活方式因素与抑郁症状之间的关联。此外，还利用加权分位数总和（WQS）指数来确定对抑郁症状影响最大的生活方式因素。
研究样本包括 3677 名参与者，其中抑郁患病率为 34.7%。根据健康生活方式评分（HLS）将参与者分为三组：低 HLS（LHLS）、中 HLS（MHLS）和高 HLS（HHLS），比例分别为 8.0%、79.8%和 12.2%。LHLS 组发生抑郁的风险显著更高（OR：5.21，95%CI：3.72 至 7.30），且抑郁严重程度更高（p 趋势<0.001），与 HHLS 组相比。此外，幸福感生活质量指数（WQS）与抑郁显著相关（OR：0.34，95%CI：0.28 至 0.40），睡眠被确定为健康生活方式的最显著因素。
本研究确立了 LHLS（工作时间长且不规律）与参与者抑郁症状风险升高之间的显著关联，强调了睡眠在这种关系中的关键作用。这些发现强调了促进放射科住院医师健康生活方式的重要性，特别是强调了充足睡眠的必要性。
