Certainly one of teens, those who advertised zero PVI regarding the past season had been somewhat very likely to getting fourteen–fifteen (compared to the sixteen–17). As with grownups, people who reported no PVI from the early in the day 12 months had been including much less likely to statement which have involved with some of the almost every other sexual habits we examined. There are zero statistically high variations in PVI regularity kinds and you may adolescent intercourse, race/ethnicity, or family income.
