The odds ratios associated with school grades were similar for delayers (0.
By far the largest difference between delayers and anticipators was in the effect of having a mother who gave birth as a teenager.
Given the selective nature of the sample, race had no effect on sexual initiation among either group of youths, but older age increased the likelihood of transition to first sex among both delayers (1.
It explained 20% of the transition among delayers and 36% among anticipators.
Anticipators are also more likely than delayers to attribute their lack of sexual experience to a lack of opportunity.
In contrast, delayers seem to have made a choice to defer intercourse, and they tend to have attitudinal, educational and maternal factors that encourage that deferment.
For preventive and intervention programs to be effective, health educators need to identify delayers and anticipators, and develop programs specific to their needs and to their distinct social, psychological and behavioral contexts.
We found little evidence that parental monitoring, influence of friends, school achievement and church attendance reduce the likelihood of initiating sex among delayers or anticipators.
