Washington: Researchers have discovered an association between childhood physical and sexual abuse and age at menarche.Researchers led by corresponding author, Renee Boynton-Jarrett, MD, assistant professor of paediatrics at Boston University School of Medicine (BUSM), found a 49 percent increase in risk for early onset menarche (menstrual periods prior to age 11 years) among women who reported childhood sexual abuse compared to those who were not abused.In addition, there was a 50 percent increase in risk for late onset menarche (menstrual periods after age 15 years) among women who reported severe physical abuse in childhood.The participants in the study included 68,505 women enrolled in the Nurses’ Health Study II, a prospective cohort study.“In our study child abuse was associated with both accelerated and delayed age at menarche and importantly, these associations vary by type of abuse, which suggest that child abuse does not have a homogenous effect on health outcomes,” Boynton-Jarrett said.“There is a need for future research to explore characteristics of child abuse that may influence health outcomes including type, timing and severity of abuse, as well as the social context in which the abuse occurs,” Boynton-Jarrett said.
