title: Seasonal variation in adolescent conceptions, induced abortions, and late initiation of prenatal care.
abstract: The monthly distribution of conceptions among adolescents and the proportion of adolescent pregnancies that are voluntarily terminated by induced abortion by month of conception are the objects of this study. Additionally, seasonal variations in the timing of initiation of prenatal care services by adolescents are investigated. Vital records files of single live births, fetal deaths, and induced terminations of pregnancy to residents in the State of South Carolina, 1979-86, were aggregated to estimate conceptions. There was a significant difference between adolescents and adults in the monthly distribution of conceptions. The peak month of adolescent conceptions coincided with the end of the school year. Pregnancies of adolescents occurring at this time further demonstrated later access of prenatal care services than conceptions occurring at other times of the year, most notably during the school term. These findings suggest that there is considerable opportunity for improving the availability of reproductive health care services for adolescents. The results specifically suggest the potential benefit of increasing adolescent pregnancy prevention efforts prior to high-risk events and increasing the availability of and access to health care and counseling services to adolescents during the school recess months of the summer.
