Physical activity and sleep problems in homeless adults

Area of Science:

• Public Health
• Sleep Science
• Exercise Physiology

Background:

• Homeless individuals in the U.S. (554,000) face significant sleep challenges and health disparities.
• Sleep quality and quantity are crucial for overall health, yet are often compromised in the homeless population.
• Identifying lifestyle factors like physical activity is vital for improving sleep outcomes in homeless adults.

Purpose of the Study:

• To investigate the association between physical activity levels and subjective sleep problems in a large sample of homeless adults.
• To determine if physical activity influences sleep duration, insufficient sleep, and unintentional daytime sleep.

Main Methods:

• A sample of 747 homeless adults from Dallas and Oklahoma participated.
• Sleep was assessed via self-report on insufficient sleep, sleep duration (short, optimal, long sleeper), and unintentional daytime sleep.
• Physical activity was measured using the BRFSS Physical Activity Questionnaire; regression analyses controlled for multiple covariates.

Main Results:

• Failure to meet physical activity guidelines was linked to a higher likelihood of being a long sleeper (OR = 2.64).
• Conversely, not meeting physical activity guidelines was associated with a lower likelihood of experiencing insufficient sleep (OR = 0.52).
• No significant association was found between physical activity and unintentional daytime sleep.

Conclusions:

• Physical activity promotion may be effective in addressing excessive sleep duration (long sleepers) among homeless adults.
• Current findings do not support physical activity as a solution for other sleep problems like insufficient sleep in this population.
• Targeted interventions focusing on physical activity could offer a promising approach for specific sleep issues in vulnerable homeless groups.
