Positive relationship between Work-to-Sleep hours Ratio and obesity: a cross-sectional study, evidence from NHANES
1Department of Gastroenterology, Jiangyou People's Hospital, Jiangyou, China.
Background:
Current approaches relying solely on work hours or sleep hours often fall short in comprehensively assessing health risks. To address this gap, this study introduces a novel metric: the Work-to-Sleep hours Ratio (WSR). The study aims to investigate the relationship between WSR and obesity.
Objective:
To investigate the correlation between WSR and obesity.
Methods:
We employing data from 7,847 participants in the National Health and Nutrition Examination Survey (NHANES) 2017-2023. Data collected from all participants included demographic variables, health-related metrics and the presence of various health conditions. Logistic regression analysis, Restricted Cubic Spline (RCS) analysis, and interaction effects were employed to support the research objectives.
Results:
In the final model of multivariate analysis showed positive relationship between WSR and obesity (OR = 1.54, 95% CI:1.33-1.77, p < 0.001). Additionally, multivariate smooth splines analysis indicated that WSR exhibited a significant inverted L-shaped nonlinear relationship with obesity (P for nonlinearity < 0.05).
Conclusion:
The study observed a positive correlation between WSR and obesity, highlighting the importance of considering both work and sleep hours in assessing public health risks.
