The present study aimed to classify participants based on mental health problems profile and to evaluate its relationship with dietary patterns among Iranian manufacturing employees.
Observational study with a cross-sectional design.
This study was conducted in Esfahan Steel Company, one of the biggest Iranian industrial manufacturing companies.
Complete data on 2942 manufacturing employees, with a mean (SD) age of 36.68 (7.31) years, were analysed.
Hospital Anxiety and Depression Scale(HADA) and General Health Questionnaire (GHQ-12) were used to evaluate anxiety and depression and psychological distress, respectively.
Three major dietary patterns, namely 'western', 'healthy' and 'traditional', were extracted using factor analysis. A two-class, one-factor structure was identified from study participants in terms of mental health problems profile based on the factor mixture model. Two identified classes were labelled as 'low mental health problems' (2683 manufacturing employees, 91.2%) and 'high mental health problems' (259 individuals, 8.8%). After adjusting for the impact of potential confounders, manufacturing employees in the highest tertile of healthy dietary pattern had lower odds of being in the high mental health problems profile class (OR=0.67, 95% CI 0.49 to 0.92). In contrast, greater adherence to Western and traditional dietary patterns was associated with increased odds of being in the high mental health problems class (OR=1.66, 95% CI: 1.18 to 2.35 and OR=1.52, 95% CI :1.10 to 2.11, respectively).
Our study provided informative pathways on the association of dietary patterns and mental health among manufacturing employees. The findings can be used by workplace health promotion policymakers in improving mental health in such study population. Interventional and prospective studies that investigate the effects of change in dietary patterns on the mental health of manufacturing employees are suggested.
本研究旨在根据心理健康问题的特征对参与者进行分类，并评估其与伊朗制造企业员工饮食模式之间的关系。
横断面观察研究。
本研究在伊朗最大的工业制造企业之一伊斯法罕钢铁公司进行。
对 2942 名制造业员工进行了分析，他们的平均（标准差）年龄为 36.68（7.31）岁，数据完整。
采用医院焦虑抑郁量表（HADA）和一般健康问卷（GHQ-12）分别评估焦虑和抑郁以及心理困扰。
因子分析提取了三种主要的饮食模式，即“西方”、“健康”和“传统”。根据因子混合模型，从研究参与者中确定了一种两分类、单因子结构，用于心理健康问题特征。两种鉴定出的类别分别为“低心理健康问题”（2683 名制造业员工，91.2%）和“高心理健康问题”（259 名员工，8.8%）。在调整潜在混杂因素的影响后，健康饮食模式最高三分位的制造业员工发生高心理健康问题特征类别的可能性较低（OR=0.67，95%置信区间 0.49 至 0.92）。相反，更多地遵循西方和传统饮食模式与高心理健康问题特征类别的可能性增加有关（OR=1.66，95%置信区间：1.18 至 2.35 和 OR=1.52，95%置信区间：1.10 至 2.11）。
本研究为制造业员工饮食模式与心理健康之间的关系提供了有价值的途径。研究结果可被工作场所健康促进政策制定者用于改善此类研究人群的心理健康。建议进行干预性和前瞻性研究，以调查饮食模式变化对制造业员工心理健康的影响。
