Abstract

OBJECTIVES

In this study, we evaluated the association between perceived stress and indicators of metabolic syndrome and how this association is mediated by sleep problems, unhealthy eating habits, and night eating syndrome, in addition to serum levels of ghrelin and cortisol in university students.

METHODS

We recruited 192 students from a public university in Mexico. Weight, height, waist circumference and blood pressure were taken in accordance with standard protocols. Validated questionnaires were used to assess perceived stress, sleep quality and eating habits. Fasting blood samples were taken to measure ghrelin, cortisol, triglycerides, glucose and HDL-C.

RESULTS

Path Analysis indicated direct positive effects of stress over PSQI (β = 0.341) and NES (β = 0.443); PSQI over NES (β = 0.233) and NES over glucose (β = 0.170), triglycerides over LDL-C (β = 0.215), waist circumference over SBP (β = 0.259). Likewise, standardized negative regression weights of PSQI over Diet Quality Index (β = -0.239) and ghrelin concentrations (β = -0.132), ghrelin over Diet Quality Index (β = -0.188) and waist circumference (β = -0.147). Diet Quality Index over triglycerides (β = -0.184); sleep duration over systolic blood pressure (β = -0.242); waist circumference over HDL-C (β = -0.256).

CONCLUSION

Psychological stress leads to increased indicators of MetS via decreased sleep quality, inadequate eating habits and eating behavior in university students.

摘要

目的

在本研究中，我们评估了大学生感知压力与代谢综合征指标之间的关联，以及这种关联如何通过睡眠问题、不健康饮食习惯和夜间进食综合征，以及血清胃饥饿素和皮质醇水平来介导。

方法

我们从墨西哥一所公立大学招募了192名学生。按照标准方案测量体重、身高、腰围和血压。使用经过验证的问卷来评估感知压力、睡眠质量和饮食习惯。采集空腹血样以测量胃饥饿素、皮质醇、甘油三酯、血糖和高密度脂蛋白胆固醇。

结果

路径分析表明，压力对匹兹堡睡眠质量指数（PSQI）（β = 0.341）和夜间进食综合征（NES）（β = 0.443）有直接正向影响；PSQI对NES（β = 0.233），NES对血糖（β = 0.170），甘油三酯对低密度脂蛋白胆固醇（β = 0.215），腰围对收缩压（β = 0.259）。同样，PSQI对饮食质量指数（β = -0.239）和胃饥饿素浓度（β = -0.132）、胃饥饿素对饮食质量指数（β = -0.188）和腰围（β = -0.147）的标准化负回归权重。饮食质量指数对甘油三酯（β = -0.184）；睡眠时间对收缩压（β = -0.242）；腰围对高密度脂蛋白胆固醇（β = -0.256）。
