The Scientific Side of Steroid Use and Abuse

Leslie Henderson is concerned about steroid abuse, not necessarily by sports luminaries like Barry Bonds and Mark McGwire, but rather by adolescents.

“There is this disconnect among young people that somehow your emotions, your thought processes—things that have to do with your brain—are separate and different from what steroids may be doing to your body—your muscles, your heart, or your liver, or anything like that,” says Henderson, a professor of physiology and neurobiology, and of biochemistry at the Geisel School of Medicine Continue reading

Spring Flings May Explain Teenage Pregnancies Peak

Researchers have found that the relative likelihood of conceiving in the month of March is higher if you’re a school-aged adolescent than if you’re an adult.

“It certainly is an intriguing finding,” says Mary Anne Jamieson, an Associate Professor in Queen’s Departments of Obstetrics & Gynecology and Pediatrics, a practicing obstetrician at Kingston General Hospital, and co-author of the paper. “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 researchers examined all 838 adolescent pregnancies that occurred in the Kingston region over a five-year period and compared the conception rates per month with a random sample of 838 adult conceptions that occurred over the same time period. While more adults conceive overall during the month of March, a larger relative percentage of adolescent pregnancies are conceived at this time compared to adult pregnancies.

This peak in adolescent conceptions coincides with the weeklong break given to all Ontario high school students.

“If Spring Break is the reason Continue reading
