ASSOCIATION BETWEEN SLEEP DISORDERS AND MENTAL DISORDERS IN THE BRAZILIAN ADULT POPULATION BASED ON DATA FROM THE NATIONAL HEALTH SURVEY (NHS) 2019

Introdução

It is known that poor sleep quality can trigger pathologies such as hypertension, heart disease, endocrine disorders, and mental disorders.

Objetivo

Therefore, the objective of this study was to evaluate the association between sleep problems and mental illness in the Brazilian adult population.

Métodos

Data from the 2019 National Health Survey (NHS) were analyzed. The dependent variable adopted was “presence of mental illness”, assessed by the question “Has a physician or health professional ever diagnosed you with another mental illness, such as anxiety disorder, panic syndrome, schizophrenia, bipolar disorder, psychosis, or OCD (Obsessive Compulsive Disorder), etc.?” (no; yes). The main exposure variable was “sleep disorders”, assessed by the question “In the last two weeks, how often have you had sleep problems, such as difficulty falling asleep, waking up frequently at night, or sleeping more than usual?” The response options “Not at all” and “Less than half the days” were categorized as “No”. The responses “More than half the days” and “Almost every day” were categorized as “Yes”. The analysis of the association between the outcome and sleep problems was performed based on the crude and adjusted odds ratio (OR) and 95% confidence interval (95% CI). Regarding the adjusted analysis, adjustments were made for sex, age, race/skin color, schooling, health insurance, area, and macro-region of residence, smoking, and alcohol consumption. Significant differences were identified based on the interpretation of the 95% CI. All analyses were stratified by sex (men; women) and age (18 to 59 years; 60 years or older). The Stata program was used, considering sample weighting (survey command).

Resultados

After adjustment, the odds ratio between sleep problems and mental illness, according to sex, was 5.03 (95% CI: 4.25; 5.97) for men and 3.54 (95% CI: 3.15; 3.98) for women; and according to age, it was 3.92 for adults and older individuals (95% CI: 3.52; 4.36 and 3.20;4.80, respectively).

Conclusões

Sleep disorders were associated with the presence of mental disorders. The chance of men, women and adults or older individuals with sleep disorders to have a mental disorders was 5.03, 3.54 and 9.92 times higher, respectively, when compared to individuals free from exposure.
