Objetivo

To estimate the prevalence of sleep disorders in the Brazilian adult population according to sociodemographic characteristics.

Métodos

Data from the National Health Survey (NHS 2019) regarding the question on sleep problems were analyzed: “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 answer options “Not at all” and “Less than half the days” were categorized as “No”. The answers “More than half the days” and “Almost every day” were categorized as “Yes”. The following variables were analyzed: a) sex; b) age group; c) schooling; d) race/skin color; e) use of private health insurance; f) type of census situation; and g) macro-region of residence; and h) federation unit. The data were analyzed in the Stata software using the set of commands for analyzing data from surveys with complex samples (survey). Statistically significant differences were considered in the absence of overlapping 95% CI.

Resultados

The prevalence of sleep disorders in the adult Brazilian population was 19.1% (95% CI: 18.6; 19.6). The following measures of prevalence of sleep disorders were identified: sex (male = 14.1% and female = 23.5%); age group (18 to 29 years = 18.2%, 30 to 44 years = 29.7%, 45 to 59 years = 28.4%, 60 to 74 years = 17.6% and 75 years or older = 6.0%); race/skin color (white = 20.0%, black = 19.8%, brown = 19.6%, yellow = 18.0% and indigenous=19.1%); schooling (none=24.5%, incomplete elementary school = 23.0%, complete elementary school =17.7%, incomplete high school = 15.7%, complete high school = 15.9%, incomplete university education = 18.6% and complete university education = 17.4%); use of private health insurance (no = 18.9% and yes =19.4%); area of residence (urban = 19.6% and rural = 15.7%), macro-regions (North = 13.6%, Northeast=18.8%, Central-West = 18.7, Southeast = 20.4% and South = 18.7%).

Conclusões

Almost two in every ten Brazilian adults had sleep disorders in 2019. Sleep disorders were more frequent in women, individuals aged 30 to 44 years, individuals of white skin color, without schooling, and living in urban areas. The Southeast region had the highest prevalence of sleep disorders in Brazil.
