PainRelief.com:  What is the background for this study?  What are the main findings?

Response: Low back pain represents a major health problem in today’s society. In this study more than 27 000 women aged 20-69 years were included in the Trøndelag Health Study, HUNT, in Norway. As in most population-based studies, women were more likely to be affected with chronic low back pain than men. Our study showed a U-shaped relationship between age at menarche (age at a woman’s first menstruation) and risk of low back pain, also after many years. Both women with an early or late age at menarche experienced higher risk of low back pain. Compared to women with menarche at age 14 years, menarche at age 11 years increased the risk by 32% and menarche at age 17 years by 43%. No association was found between age at menopause and risk of low back pain.
