ABSTRACT

We examined the association between self-reported sleep quality, sleep duration, and dietary patterns among police officers in the Buffalo Cardio-Metabolic Occupational Stress (BCOPS) study.

422 police officers aged 21–74 (2004–2009).

We used a cross-sectional study design and obtained sleep quality and duration from responses to the 19-item Pittsburgh Sleep Quality Index. Using 46 energy-adjusted food groups derived from a 125-item food frequency questionnaire, we identified dietary patterns using exploratory factor analysis. Multiple linear regression analysis was used to examine the associations of sleep quality and duration with the derived dietary patterns.

We identified major dietary patterns: fruits and vegetables (FV), dairy products, starches and fried foods, and meat and eggs. Individuals with poor sleep quality had a lower average FV score than those with optimal sleep (β [SE] = −0.32 [0.13]; p = .01). Significant interactions were observed between sex and the FV and dairy products dietary patterns, where women with poor sleep quality had a lower mean FV score compared to women with optimal sleep quality (β [SE] = −0.81 [0.29]; p = .01). Women with < 6 hours sleep duration had a lower mean dairy score compared to women with ≥ 7 hours sleep duration (β [SE] = −0.69 [0.29]; p = .02). We did not observe these associations among men.

Among women, good sleep quality and long sleep duration were associated with a dietary pattern high in consumption of both fruits and vegetables and dairy products.

摘要

我们在布法罗心脏代谢职业压力 (BCOPS) 研究中检查了警官自我报告的睡眠质量、睡眠时间和饮食模式之间的关联。

422 名 21-74 岁的警官（2004-2009 年）。

我们使用横断面研究设计，并从对 19 项匹兹堡睡眠质量指数的反应中获得睡眠质量和持续时间。使用来自 125 项食物频率问卷的 46 个能量调整食物组，我们使用探索性因素分析确定了饮食模式。多元线性回归分析用于检查睡眠质量和持续时间与衍生饮食模式的关联。

我们确定了主要的饮食模式：水果和蔬菜 (FV)、乳制品、淀粉和油炸食品以及肉类和鸡蛋。睡眠质量差的个体的平均 FV 评分低于睡眠质量最佳的个体（β [SE] = -0.32 [0.13]；p = .01）。在性别与 FV 和乳制品饮食模式之间观察到显着的相互作用，其中睡眠质量差的女性的平均 FV 评分低于睡眠质量最佳的女性（β [SE] = -0.81 [0.29]；p = .01 ）。与睡眠时间 ≥ 7 小时的女性相比，睡眠时间小于 6 小时的女性平均乳制品评分较低（β [SE] = -0.69 [0.29]；p = .02）。我们没有观察到男性之间的这些关联。

在女性中，良好的睡眠质量和较长的睡眠时间与高摄入水果、蔬菜和乳制品的饮食模式有关。
