Purpose: The objective of this research is to describe aspects of the
organization of adolescent sexual behavior in order to understand fact
ors associated with risk for sexually transmitted diseases (STD). Meth
ods: Subjects were 82 females (ages 16-19 years; 77% African-American)
participating in a larger STD study. Subjects completed diaries for e
ach coital event, recording date of event, partner initials, condom us
e, and use of drugs or alcohol before intercourse. Partner change was
defined as any event for which the sex partner initials differed from
those listed for the most recent previous coital event. Results: The 8
2 subjects recorded 1265 coital events; the average span of the record
s was 10 weeks. Intercourse was least likely on Sundays (154 of 1265;
12.2%) and most common on Friday and Saturday (221 of 1265 for each da
y; 17.5%). The proportion of coital events associated with drugs or al
cohol increased from Sunday to Saturday, although the proportion of co
ital events in which a condom was used did not vary significantly. Int
ercourse was most common in spring and summer, and least frequent in w
inter. Conclusions: These data indicate substantial temporal organizat
ion of adolescent sexual behaviors that may be related to risk of sexu
ally transmitted diseases. Some STD-preventive interventions may be mo
st effective when targeted to higher risk times. (C) Society for Adole
