Key Points

This research aims to identify how aspects of first sexual intercourse affect relationship types and statuses among young adults, considering mental health and demographic factors.
Analyzed data from a 2017 Swiss national survey with 4718 young adults (2718 females, 2016 males)
Participants categorized into 'Single', 'Stable/monogamous', and 'Casual relationship types'
Used multinomial logistic regression to assess associations, stratified by gender
Older age at sexual debut linked to lower odds of being in a relationship
Higher mental health scores observed in participants in stable relationships
For women, casual relationships were associated with lower odds of reporting uncertainty about timing (OR = 0.37, 95% CI [0.17,0.84], p = .02)
