Children's perceptions of their relationships with their parents and p
eers in 1976 and 1981, respectively along with other salient anteceden
t variables, were related to their age at first sexual intercourse as
reported in 1987. Data came from the National Survey of Children, a th
ree-wave longitudinal study of 1,145 children age 7-11 (Wave 1), 12-16
(Wave 2), and 18-22 (Wave 3). Antecedent variables were taken from bo
th Round 1 and Round 2 surveys. When the same variables were present a
t bath times, the more recent data were used if the survey occurred pr
ior to age at first sexual intercourse; if not, the Round 1 data were
used. Separate analyses were run to predict timing of sexual intercour
se for males and females. Age of first date, dating often, number of f
riends perceived to have had sex at age 16 being Black, having parents
undergo marital changes during the child's school years, and fighting
at school were the most significant predictors of age at first sexual
intercourse among mates. All of these variables except fighting at sc
hool and dating frequency were significant predictors among females. A
dditional significant variables predicting age of first sex among fema
les were menarche, parents' education, mother's coercive behavior and
love withdrawal, and attitudes about attending religious services.
