Study co-author Mary Anne Jamieson, an associate professor in Queen's University's and a practicing obstetrician at Kingston General Hospital, says the relative likelihood of conceiving in the month of March is higher for a school-aged adolescent in Ontario than for an adult.
The researchers examined all 838 adolescent pregnancies that occurred in the Kingston, Ontario, during a five-year period and compared the conception rates per month with a random sample of 838 adult conceptions that occurred during the same time period.
More adults conceive overall during the month of March, but a larger relative percentage of adolescent pregnancies are conceived during this period compared to adult pregnancies, Jamieson says.
"It certainly is an intriguing finding," Jamieson says in a statement. "This adolescent pregnancy peak may be explained by biological reasons such as variations in fertility over the course of a calendar year, but it's also possible that this increased conception rate in March is because of spring break."
The study is scheduled to be published in the Journal of Pediatric & Adolescent Gynecology.
