[Changes in male condom use at first and last sexual intercourse in different birth cohorts]

Characterize the use of condoms in the first and last sexual intercourse in different birth cohorts, to observe possible differences among generations.

Using the National Survey of Boys, Girls and Women, 2015, representative at the national level, we adjust Poisson regression models to find associations between variables of interest and the use of condoms in first and last intercourse.

Women from younger cohorts, with higher education and wealth are more likely to use a condom in their first and last sexual intercourse; speaking an indigenous language is associated with a lower likelihood of condom use at both events. Using condom in sexual debut increases the likelihood of using in last intercourse.

There is a generational change in condom use at first and last sex among younger cohorts. The use of the condom in sexual debut favors its later use.
