Abstract

This paper examines sleep patterns in Romania, a country where long working hours and significant household responsibilities may impact rest. The study highlights key factors influencing perceived sleep quality, with the aim to offer insights for clinicians. Based on a cross-sectional survey 835 with Romanian respondents by the Francophone Space of Pneumology from 2019 to 2020, the study predates the COVID-19 pandemic and therefore avoids potential post-pandemic sleep disruptions. Participants reported their sleep habits, medical conditions, psychological well-being, and work conditions. The study assesses how these factors relate to sleep quality, sleep duration, insomnia, and sleep disturbances. Multivariate analysis reveals that individual perceptions of sleep quality can be misleading when analyzed in isolation. Through hierarchical models, we identify specific predictors of sleep quality. Multivariate analysis showed that good bedroom conditions (OR = 1.63) and physical activity (OR = 1.45) were associated with better sleep perception. Night shifts, female gender, and co-sleeping with pets (OR = 3.68) increased risk of sleep problems. Medical predictors (e.g., STOP-Bang) were not significantly associated. The results are also presented in a practical dashboard, helping healthcare professionals assess sleep disorders more effectively while identifying potential biases in self-reported sleep quality.
