How Sleep Quality and Excess Weight Are Linked Differently in Men and Women, Considering Lifestyle and Health Factors
Updated
Abstract
Poor sleep quality and short sleep duration are associated with a 21% increase in odds of excess weight among female subjects.
- In female participants, poor sleep quality and short sleep duration are linked to higher body mass index (BMI).
- Chronic conditions, depression, and diet quality were identified as mediating factors for the impact of poor sleep quality on BMI in females.
- Screen time before bed was a significant mediator for the relationship between short sleep duration and BMI, accounting for approximately 5% of the total effect.
- No significant associations were observed between sleep quality, sleep duration, and BMI in male subjects.
- The findings suggest important sex differences in the relationship between sleep and weight, indicating a need for targeted approaches.
