Seasonality of First Coitus in the U.S. Social Biology 39 (Spring-Summer 1992): 1-14. Also: http://www.ncbi.nlm.nih.gov/pubmed/1514113 Cohort(s): NLSY79 Publisher: Society for the Study of Social Biology Keyword(s): Age at First Intercourse; Household Composition; Seasonality; Sexual Activity; Sexual Experiences/Virginity; Transition, School to Work Permission to reprint the abstract has not been received from the publisher. Recent attention to causes of seasonality of births leads to an interest in seasonality patterns in the antecedents to birth, including gestational length, conception, and coital activity. In this paper we study the beginning of the process: first intercourse among adolescents and young adults. Analysis of a small and local dataset is suggestive that loss of virginity is particularly likely during the summer. A test of this "Summer Vacation Theory" using a large national dataset supports the generality of the phenomenon. Further, a prediction that seasonality patterns will change during the transition from high school to work and college is tested and supported. The existence of both biological and psycho-social mechanisms is suggested. Policy implications are reviewed. |

The Seasonality of Onset of Adolescent Sexuality Presented: Toronto, Canada, Population Association of America Meetings, May 1990 Cohort(s): NLSY79 Publisher: Population Association of America Keyword(s): Adolescent Fertility; Hispanics; Racial Differences; Seasonality; Sexual Activity; Sexual Behavior; Sexual Experiences/Virginity Permission to reprint the abstract has not been received from the publisher. Recent attention to seasonality of births leads to an interest in seasonality patterns in the antecedents to birth, including gestational length, conception, and coital activity. In this paper the authors begin at the very beginning of the process and study the seasonality of the onset of sexual intercourse. Data come from two sources, the ADSEX (Adolescent Sexuality) data and the NLSY data. Analysis of the ADSEX data suggests a summer peak in onset of adolescent coitus. This finding suggests a simple "Summer Vacation Theory" in which the likelihood of a virgin adolescent making the transition to nonvirginity increases immediately after school is out for the summer. This theory is then tested by cross-validating patterns in the ADSEX data against those in the NLSY data. The patterns in this national dataset match those from ADSEX, in that a large peak is found in June and, to a lesser extent, in July. These patterns are consistent across race and period, although some minor differences between Hispanics and other races and between high school and college onset are noted and interpreted. |
