Age at Menarche and First Pregnancy Among Psychosocially At-Risk Adolescents
We sought to determine which factors influence the association between menarche
and conception among adolescent study participants (n = 1030), who
demonstrated an earlier age of menarche than did national samples. Age at first
sexual intercourse (coitarche) mediated the relationship between age at menarche
and first pregnancy among White girls, whereas gynecologic age at coitarche (age
at coitarche minus age at menarche) and age at menarche explained the timing of
the first pregnancy among Black and Hispanic girls. Pregnancy prevention
interventions to delay coitarche should also include reproductive education and
contraception
