Association between a healthy lifestyle and the prevalence of depression in radiology residents in China: findings from a nationwide survey.
Article in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe 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.
designCross-sectional study.
settingThe 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.
participants3677 radiology residents in 31 provinces of China. PRIMARY AND SECONDARY OUTCOME MEASURES: 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.
resultsThe 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.
conclusionThe 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.
