Abstract

Background: Insulin resistance and associated metabolic health symptoms remain a primary global health concern. In addition to healthy dietary and nutritional programs, sleep duration is closely related to and has been linked to healthy metabolism. This study aimed to determine the link between insulin resistance and sleep duration and the dietary intake of live microbes.

Methods: Data were collected from 15,927 participants in the National Health and Nutrition Examination Survey database from 2005 to 2018; this sample is equivalent to 209,316,590 individuals in the United States. The participants were categorized according to their consumption of foods containing live microbes: low, medium, high, and medium-high. The relationship between diets containing live microbes and the triglyceride-glucose index was analysed using a weighted multivariate linear regression model with a multistage sampling approach. The individuals were deemed to have insulin resistance if their homeostatic model assessment score for insulin resistance was ≥ 2. The relationship between diets containing live microbes and insulin resistance status was assessed using weighted multivariate logistic regression analyses. The mediating role of sleep duration on the relationship between diets containing live microbes and the triglyceride-glucose index was also examined.

Results: After accounting for potential confounders, diets containing live microbes at medium and medium-high levels were significantly associated with a reduced triglyceride-glucose index. The medium and medium-high levels of live microbial intake were also associated with a lower risk of insulin resistance. Within the 6-9 hours' sleep duration range, the indirect effect of medium and medium-high levels of live microbes on the triglyceride-glucose index was observed, accounting for 2.95% and 6.08% of the overall change, respectively.

Conclusions: This study suggests an association between a diet rich in medium and medium-high viable microbes, lower triglyceride-glucose index values, and a reduced risk of developing insulin resistance. Additionally, a sleep duration of 6-9 h may mediate this association.

睡眠时间是膳食中活微生物摄入量与胰岛素抵抗之间关系的调解因素:一项横断面研究。
背景:胰岛素抵抗和相关的代谢健康症状仍然是一个主要的全球健康问题。除了健康的饮食和营养计划,睡眠时间也与健康的新陈代谢密切相关。这项研究旨在确定胰岛素抵抗、睡眠时间和饮食中活微生物的摄入量之间的联系。方法:收集2005 - 2018年全国健康与营养检查调查数据库中15927名参与者的数据;这个样本相当于美国的209,316,590人。参与者根据他们对含有活微生物的食物的摄入量进行分类:低、中、高和中高。采用多阶段抽样加权多元线性回归模型分析含活微生物饮食与甘油三酯-葡萄糖指数之间的关系。如果胰岛素抵抗的稳态模型评估得分≥2分,则认为个体存在胰岛素抵抗。使用加权多变量logistic回归分析评估含有活微生物的饮食与胰岛素抵抗状态之间的关系。睡眠时间对含活微生物饮食与甘油三酯-葡萄糖指数之间关系的中介作用也进行了研究。结果:在考虑了潜在的混杂因素后,含有中等和中高水平活微生物的饮食与甘油三酯-葡萄糖指数的降低显著相关。中等和中高水平的活微生物摄入也与较低的胰岛素抵抗风险相关。在6-9小时的睡眠时间范围内,观察到中、中高水平的活微生物对甘油三酯-葡萄糖指数的间接影响,分别占总体变化的2.95%和6.08%。结论:本研究表明,富含中、中高活菌的饮食、较低的甘油三酯-葡萄糖指数值和较低的胰岛素抵抗风险之间存在关联。此外,6-9小时的睡眠时间可能介导这种关联。

期刊介绍: Lipids in Health and Disease is an open access, peer-reviewed, journal that publishes articles on all aspects of lipids: their biochemistry, pharmacology, toxicology, role in health and disease, and the synthesis of new lipid compounds. Lipids in Health and Disease is aimed at all scientists, health professionals and physicians interested in the area of lipids. Lipids are defined here in their broadest sense, to include: cholesterol, essential fatty acids, saturated fatty acids, phospholipids, inositol lipids, second messenger lipids, enzymes and synthetic machinery that is involved in the metabolism of various lipids in the cells and tissues, and also various aspects of lipid transport, etc. In addition, the journal also publishes research that investigates and defines the role of lipids in various physiological processes, pathology and disease. In particular, the journal aims to bridge the gap between the bench and the clinic by publishing articles that are particularly relevant to human diseases and the role of lipids in the management of various diseases.
