ABSTRACT Objective: The objective of this research was to describe the sexual behaviors and condom use in the Brazilian population. Methods: This is a cross-sectional, descriptive study, which used data from 88,531 individuals aged 18 years old or older, who answered the second edition of the National Health Survey carried out in 2019. Prevalence was estimated with the respective 95% confidence intervals for each sexual behavior indicator and condom use according to gender, age, race/skin color, educational level, and region of residence. Results: The majority of the Brazilian population has had sexual intercourse at some point in their lives (93.9%). Mean age of initiation was 17.3 years. Prevalence of consistent condom use was only 22.8%, being even lower among women (20.9%). Moreover, 59% of the population reported not having used a condom in the past 12 months, the main reason being trusting their partner (73.4%). The use of health services to obtain condoms was only 10.7%. It was observed that women, individuals with a higher age group, less education, and income had worse results in relation to the analyzed indicators, in addition to regional disparities. Conclusion: Low prevalence of condom use was observed in the Brazilian population. In addition, important socioeconomic and demographic disparities were observed, pointing out the need to revisit, strengthen and expand public policies in the sexual and reproductive health field in order to prevent risky sexual behaviors and promote condom use, including double protection.
