This prevalence was higher in the population aged 18-29 years old (3.2%; 95%CI 2.8-3.7) compared to older individuals (1.1%; 95%CI 0.8-1.3), and among residents of the North (3.2%; 95%CI 2.5-3.8) and Northeast Regions (3.0%; 95%CI 2.5-3.8) when compared to residents of the Southeast Region (2.0%; 95%CI 1.6-2.3).
