Self-reported sleep duration in Finnish general population

Area of Science:

• Public Health
• Sleep Medicine
• Epidemiology

Background:

• Short and long sleep durations are associated with increased mortality and health risks.
• Limited detailed knowledge exists on general population sleep duration groups and their health implications.
• Understanding sleep duration determinants is crucial for public health interventions.

Purpose of the Study:

• To characterize short and long sleep duration groups in the Finnish general population.
• To identify statistically independent determinants of sleep duration.
• To analyze associations between sleep duration and health, sociodemographic, and lifestyle factors.

Main Methods:

• Utilized data from the Finnish Health 2000 Survey.
• Included a representative sample of 9,922 adults (18-29 and 30+ years).
• Employed multivariable analysis to identify independent determinants of sleep duration.

Main Results:

• Key independent determinants of sleep duration included gender, physical tiredness, sleep problems, marital status, occupation, and physical activity.
• These factors accounted for approximately 16% of the variance in sleep duration.
• A dose-response relationship was observed between sleep duration and several determinants.

Conclusions:

• While key determinants of sleep duration were identified, they explain a limited portion of variance, indicating multifactorial influences.
• Further clinical analysis is needed to understand the health risks associated with short and long sleep durations.
• Findings highlight the complexity of sleep duration and its determinants in the general population.
