7As for aggravating and relieving factors, rest (sitting, lying down) helped reduce pain. Standing for long periods of time increased painful symptoms. Women who had help with daily household chores were also less likely to develop back pain suggesting that motherhood itself (or perhaps the activities associated with motherhood) are risk factors for low back pain.
