Objective:

To analyse sexual behaviours according to sex and socioeconomic status among university students at a public university in Chile.

Methodology:

A quantitative, observational, analytical, cross-sectional, cross-sectional study was conducted in a sample of 94 first-year students at a public university in Chile. Data collection was carried out through the application of a descriptive questionnaire on socio-demographic background and sexual behaviour.

Results:

69.1% of the university students started sexual activities when they were 16 years old or older. The male sex presented a higher frequency of risk behaviours compared to the female sex. No statistically significant differences were found in the frequency of risk behaviours by socioeconomic level.

Conclusion:

Socioeconomic status is not a determinant of the predominant risky sexual behaviours among males.
