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]; = .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]; = .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]; = .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.: BCOPS: Buffalo Cardio-Metabolic Occupational Stress study; BMI: body mass index; FFQ: food frequency questionnaire; FV: fruits and vegetables; KMO: Kaiser-Meyer-Olkin test; MET: metabolic equivalent of task score; PSQI: Pittsburgh Sleep Quality Index questionnaire.
我们研究了布法罗心脏代谢职业应激（BCOPS）研究中警察的自我报告睡眠质量、睡眠时间和饮食模式之间的关系。共有 422 名年龄在 21-74 岁（2004-2009 年）的警察参与了这项横断面研究。我们使用 19 项匹兹堡睡眠质量指数（PSQI）来获取睡眠质量和时长的信息。通过对包含 125 种食物的食物频率问卷（FFQ）中 46 种能量调整后的食物组进行探索性因子分析，我们确定了饮食模式。使用多元线性回归分析来研究睡眠质量和时长与衍生饮食模式之间的关系。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蛋类。睡眠质量差的个体的 FV 得分平均值低于睡眠质量最佳的个体（β[SE] = -0.32[0.13]；p = 0.01）。在性别与 FV 和乳制品饮食模式之间观察到显著的交互作用，睡眠质量差的女性的 FV 得分平均值低于睡眠质量最佳的女性（β[SE] = -0.81[0.29]；p = 0.01）。睡眠时长<6 小时的女性的乳制品得分平均值低于睡眠时长≥7 小时的女性（β[SE] = -0.69[0.29]；p = 0.02）。我们在男性中未观察到这些关联。在女性中，良好的睡眠质量和较长的睡眠时间与摄入大量水果和蔬菜以及乳制品的饮食模式相关。
