considering the diet, as a whole (dietary patterns), can provide more information regarding dietary guidelines to decrease health problems and improve quality of life (QoL) of industrial workers.Therefore, the aims of this study were to identify major dietary patterns and to evaluate their association with quality of life among Iranian industrial employees.
This cross-sectional study was conducted on 3,063 employees of Isfahan Steel Company, Isfahan, Iran, in 2015. Dietary data were evaluated through a validated form of a food frequency questionnaire. Exploratory factor analysis was used to extract major dietary patterns,. To assess the QoL, Euro-QoL five- dimension questionnaire was used. Latent class analysis was used to classify participants based on QoL. Multivariable logistic regression was employed to evaluate the association between dietary patterns and QoL.
Three dietary patterns, i.e. western, healthy and traditional, and two classes, i.e. high and low quality of life. were identified from study participants. Lower adherence to the healthy dietary pattern increased the risk of being in low QoL class in which subjects in the lowest tertile of healthy dietary intake had higher odds of being in low QoL class (adjusted OR (AOR): 1.51, 95% CI: 1.19-1.91). However, subjects in the lowest tertile of traditional diet, low adherence, had 30% lower risk of belonging to the low QoL class (AOR:0.70, 95% CI: 0.55-0.88). Higher adherence to western dietary pattern increased the risk of low quality of life, but it was not statistically significant.
Higher adherence to a healthy diet and lower adherence to traditional dietary pattern were associated with better QoL in manufacturing employees.
考虑到饮食作为一个整体（饮食模式）可以提供更多关于饮食指南的信息，以减少健康问题并提高工业工人的生活质量（QoL）。因此，本研究的目的是确定主要的饮食模式，并评估它们与伊朗工业工人生活质量的关系。
本横断面研究于 2015 年在伊朗伊斯法罕钢铁公司对 3063 名员工进行。通过验证后的食物频率问卷评估饮食数据。采用探索性因子分析提取主要饮食模式。为了评估生活质量，采用欧洲生活质量五维度问卷。采用潜在类别分析根据生活质量对参与者进行分类。采用多变量逻辑回归评估饮食模式与生活质量之间的关系。
从研究参与者中确定了三种饮食模式，即西方、健康和传统，以及两种类别，即高质量和低质量的生活。较低的健康饮食模式的依从性增加了处于低生活质量类别的风险，其中健康饮食摄入最低三分位的受试者处于低生活质量类别的可能性更高（调整后的比值比（AOR）：1.51，95%CI：1.19-1.91）。然而，传统饮食低依从性最低三分位的受试者属于低生活质量类别的风险降低了 30%（AOR：0.70，95%CI：0.55-0.88）。较高的西方饮食模式的依从性增加了低生活质量的风险，但无统计学意义。
在制造业员工中，较高的健康饮食依从性和较低的传统饮食模式依从性与更好的生活质量相关。
