Association between beverage quality with sleep disorders and quality of life: a cross-sectional study.

Background/objectives: The interplay between beverage consumption patterns and critical aspects of health, such as quality of life (QoL) and sleep disorders, has been increasingly recognized. This study is essential as it explores how the Healthy Beverage Index (HBI) and Healthy Beverage Score (HBS) relate to sleep disorders and QoL in a diverse adult population, highlighting their impact on various health aspects.

Subjects/methods: A cross-sectional analysis was conducted using data from the Shiraz University of Medical Sciences Employees Health Cohort Study (SUMS EHCS), encompassing 3380 participants aged 20-65. Data collection included a 119-item Food Frequency Questionnaire (FFQ) and comprehensive anthropometric, lifestyle, and health-related assessments. HBI and HBS were computed to evaluate beverage consumption patterns, and their associations with sleep quality and QoL were analyzed using logistic regression models.

Results: Higher HBI scores were significantly associated with 16% improved QoL (OR: 1.16, 95% CI: 1.02-1.29, p = 0.034) and a 17% reduced risk of sleep disorders (OR = 0.83, 95% CI: 0.69-0.99, p = 0.039). However, HBS did not significantly correlate with QoL or sleep quality.

Conclusion: As indicated by higher HBI scores, the findings emphasize that promoting healthier beverage choices could enhance sleep quality and overall life satisfaction.
