Resumen

SOUZA, Tiago Odilio de et al. Prevalence of unprotected sexual activity in the Brazilian population and associated factors: National Health Survey, 2019. Epidemiol. Serv. Saúde [online]. 2022, vol.31, n.2, e2022234.  Epub 26-Sep-2022. ISSN 1679-4974.  http://dx.doi.org/10.1590/s2237-96222022000200027.

Objective:

To estimate prevalence of unprotected sexual activity and associated factors in the Brazilian population.

Methods:

This was a cross-sectional study with 61,523 adults aged 18 years or older who took part in the 2019 National Health Survey. We estimated prevalence of unprotected sexual activity in the last year. We analyzed association of socioeconomic and demographic variables with the outcome using Poisson regression, estimating prevalence ratios (PR) and 95% confidence intervals (95%CI).

Results:

Prevalence of unprotected sexual activity was 76.9% (95%CI 76.3;77.6), being higher in all the country’s regions in comparison to the Northern region, as well as being higher among people living in rural areas (PR = 1.04; 95%CI 1.03;1.06), females (PR = 1.06; 95%CI 1.05;1.08), participants aged 60 years or older (PR = 1.33; 95%CI 1.27;1.38), married individuals (PR = 1.25; 95%CI 1.23;1.27) and those with less education (PR = 1.05; 95%CI 1.03;1.06).

Conclusion:

Strategies aimed at groups with higher prevalence of unprotected sexual activity are necessary.
