Union status and sexual risk behavior among men in their 30s.

Context: Understanding the relationship between union status and men's sexual risk behavior in their 30s is important to ensure appropriate reproductive health services for men in middle adulthood.

Methods: Data from 1,083 men aged 34-41 who participated in the 2008-2010 wave of the National Survey of Adolescent Males were used to examine differentials in sexual risk behaviors by union status, past risk behavior and selected characteristics. Bivariate tabulations were done to assess relationships between current risk behavior and background variables, multinomial regression analysis was conducted to identify associations between union status and past risk behavior, and logistic regression analysis was used to assess associations between current behavior and both union status and past behavior.
