Objective:

To establish the relationship between sexual behaviors and substance use, and intimate partner violence according to the 2022 National Youth Survey of Chile.

Methods:

A quantitative, analytical, correlational study extracted from the 2022 National Youth Survey database, including all young people aged 15 to 29 who have already initiated sexual activity.

Results:

The average age of sexual initiation is between 15 and 19 years. 93.6% of the sample has had fewer than 4 sexual partners in the past year. 47.3% have been tested for human immunodeficiency virus. 96.7% of the sample has never had a sexually transmitted infection (STI). Psychological violence predominates, with 4.8% experiencing it from their partner and 4.1% towards their partner, surpassing aspects of physical, sexual, or economic violence.

Conclusion:

There is a relationship between sexual behaviors, substance use, and intimate partner violence among young couples. Early sexual initiation, condom use, human immunodeficiency virus testing, and the consumption of alcohol, cigarettes, and marijuana are significantly associated with intimate partner violence.
