Abstract
The study objective was to assess if insomnia, along with other factors, can impact the physical and mental quality of life (QOL) of the Lebanese general population. This cross-sectional study, conducted between November 2017 and March 2018, enrolled 756 community-dwelling participants. A first linear regression, using the SF-12 PCS score as the dependent variable, showed that having a family history of insomnia problems (β = 1.107, p = 0.026) was significantly associated with higher physical QOL (higher SF-12 PCS score), whereas increased stress (β = 0.048, p = 0.015) was significantly associated with lower physical QOL. A second linear regression, using the SF-12 MCS score as dependent variable, showed that having increased age (β = -0.079, p < 0.001) was significantly associated with lower mental QOL. Despite its cross-sectional design and the modest sample size, this study adds to the evidence that insomnia, along with other factors (including sociodemographic and psychological factors), can have a detrimental impact on both physical and mental QOL of participants.
