Introduction:

Many lifestyle habits can negatively affect sleep quality (SQ) and lead to poor quality of life. This makes it important to determine the prevalence of poor SQ in the population and the lifestyle habits that may be associated with it, with a view to designing appropriate interventions for improving SQ. The aim of this study was to examine the prevalence of poor SQ among the population of Salamanca (Spain) and its relationship with specific lifestyle habits

Method:

A cross-sectional study was carried out between July and November 2019. SQ was studied in 261 patients using the Pittsburgh Sleep Quality Index, and the frequency with which patients performed a series of lifestyle habits was quantified. The association between variables was assessed using multivariate binary logistic regression.

Results:

Almost half of the study population (48.7%) was found to have poor SQ. Physical exercise was a protective factor against poor SQ (OR = 0.221; CI95%: 0.081-0.603). Risk factors for poor SQ included being disturbed at night (OR = 3.606; CI95%: 1.892-6.872), going to bed preoccupied (OR = 3.145; CI95%: 1.528-6.471), reading trivial material (OR = 2.475; CI95%: 1.208-5.070), and playing video games (OR = 3.639; CI95%: 1.326-9.984).

Conclusions:

In Salamanca (Spain), almost half of the study population stated that they suffered poor SQ. Although numerous lifestyle habits that may relate to poor SQ were studied, a statistically significant relationship was only found for a few of them.
