I haven't had a period in almost a year; should I be concerned?

Swedish researchers have shown that irregular periods in female athletes may be caused by high levels of male hormones, rather than just by not eating enough food, the commonly accepted theory (Fertility and Sterility, Volume 79, Issue 4, 2003). The researchers showed that many female athletes who have irregular periods have much higher blood levels of masculinizing hormones than those with regular periods.

Female athletes with irregular periods and high male hormone levels usually also have larger muscles and bones, and are stronger than the athletes with regular periods. This study suggests that women who have high blood levels of male hormones are more likely to become athletes and the masculinizing hormones that make them better athlete are more likely to cause irregular periods. Check with your doctor or a gynecologist.
