High Prevalence of Sleep Disorders Uncovered in Yverdon-les-Bains Neighborhoods

Recent research by scientists from EPFL and Haute École d'Ingénierie et de Gestion du Canton de Vaud (HEIG-VD), in collaboration with the municipality of Yverdon-les-Bains, has revealed a significantly high rate of sleep disorders among local residents. The study involved analyzing sleep quality through a comprehensive psychometric questionnaire completed online by participants across the city. Findings showed that approximately 90% of respondents experienced poor sleep quality, with about 15% reporting excessive daytime sleepiness. These results highlight a concerning public health issue affecting the community.

The study also mapped the distribution of sleep disturbances, finding that lower-income neighborhoods with limited public transport and higher traffic noise levels had higher instances of sleep issues. Interestingly, residents in these areas reported better perceived sleep quality despite objectively experiencing more sleep disturbances, indicating a disconnect between perceived and actual sleep health.

This research emphasizes the importance of early detection and targeted interventions, especially since chronic sleep disorders are linked to increased risks of cancer, cardiovascular problems, and cognitive decline. Moving forward, the researchers plan to engage with local officials through workshops and informational campaigns to improve sleep health and address environmental factors contributing to sleep disturbances.

The study aligns with wider national trends, as the Swiss Federal Office of Public Health reports that about one-third of Swiss residents suffer from sleep disorders, a figure steadily rising over the past 25 years. Similar studies in Geneva showed that half to 60% of the population experiences sleep deficiency. These statistics shed light on the urgent need for public health policies aimed at reducing urban stressors like noise and air pollution. The Yverdon-les-Bains initiative includes citizen science components and collaborations between university programs and municipal authorities to promote urban health and well-being.

The research used the Pittsburgh Sleep Quality Index (PSQI), a self-assessment tool evaluating various aspects of sleep over a month, including subjective sleep quality and use of sleeping pills. The findings underscore the critical need for early intervention and community education to improve sleep health across urban populations.
