Quality of sleep and quality of life in people with sleep bruxism.

Introdução

Sleep Bruxism (SB) has emerged as a prevalent and distressing condition. Several associated factors have been explored for SB in children, adults, and older adults, including behavioral abnormalities and sleep disturbances. Additionally, it examines the negative effects of bruxism on overall health and quality of life. We hypothesized that SB, whether associated with other sleep disorders or not, negatively impact both the quality of sleep, the overall quality of life and mental well-being of affected individuals.

Objetivo

The hypothesis of this study is that SB, whether associated with other sleep disorders or not, can negatively impact both the quality of sleep and the overall quality of life and mental well-being of affected individuals.

Métodos

This cross-sectional study included participants aged 15 to 80 years, residing in São Paulo, Brazil. All participants provided signed consent forms.
The questionnaires used were: Bruxism Questionnaire, Pittsburgh Sleep Quality Index (PSQI); Epworth Sleepiness Scale (ESS); Beck Anxiety Inventory (BAI); Well-Being Index (WHO5); Oral Health Impact Profile (OHIP-14). The questionnaires were completed in an online format, with a sample of 532 people.
Statistical analysis: Correspondence Analysis to evaluate the profile of each age group was performed. Logistic Regression models are used with the dependent variables: gender, age, quality of life, sleep quality, and well-being. A significance level of 5% is adopted.

Resultados

Women were 1.78 times more likely to experience SB than men (Odds Ratio (OR) = 1.78; 95% Confidence Interval (CI): 1.17 to 2.72). Women had 2.40 times more likely to experience Nocturnal Clenching compared to men (OR = 2.40; 95% CI: 1.55 to 3.70). Those who experience SB, have 3.05 times more anxiety symptoms (BAI); OR = 3.05; 95% CI: 1.18 to 7.86) and 5.76 times lesser well-being (WHO5); (OR = 5.76; 95% CI: 3.20 to 10.37). Those who reported sleep bruxism had nearly 20 times more somnolence (ESS); (OR = 19.75; 95% CI: 2.62 to 148.67).

Conclusões

Women had 78 % higher risk of SB, compared to men. It is concluded that SB had a negative impact on the quality of life and sleep.
