Abstract

Adequate sleep quality is crucial for overall health, affecting physiological and psychological well-being. This systematic review examined the relationship between sleep quality, Body Mass Index (BMI), dietary habits, and socioeconomic factors among young adults (18-35 years). A total of 39 studies published since 2019 were reviewed. A meta-analysis of 20 studies revealed a significant positive association between poor sleep quality and higher BMI, with high heterogeneity (I² = 88.22%). Evidence indicates a bidirectional relationship where short sleep duration contributes to weight gain, while higher BMI reduces sleep quality and duration. Healthy diets, such as the Mediterranean diet and calcium-rich products, are associated with improved sleep quality, while socioeconomic factors, including financial stress, influence these relationships and highlight health inequalities. However, most studies did not explore causal relationships, directionality, between these variables and changes in sleep quality. Future research should interpret these mechanisms and develop strategies to improve sleep hygiene and overall health.

年轻人睡眠质量、体重指数、饮食和社会经济属性的关系：一项系统综述。

充足的睡眠质量对整体健康至关重要，影响着生理和心理健康。本系统综述研究了年轻人（18-35岁）的睡眠质量、身体质量指数（BMI）、饮食习惯和社会经济因素之间的关系。共回顾了2019年以来发表的39项研究。对20项研究的荟萃分析显示，睡眠质量差与较高的BMI之间存在显著的正相关，且异质性高（I2 = 88.22%）。有证据表明，睡眠时间短会导致体重增加，而BMI指数高则会降低睡眠质量和持续时间。健康饮食，如地中海饮食和富含钙的产品，与改善睡眠质量有关，而社会经济因素，包括经济压力，影响这些关系并突出健康不平等。然而，大多数研究并没有探索这些变量与睡眠质量变化之间的因果关系和方向性。未来的研究应该解释这些机制，并制定策略来改善睡眠卫生和整体健康。
