Doing aerobic exercise can reduce the level of depressive symptoms experienced by women who have had a baby in the past year | British Journal of General Practice |via National Institute for Health Research (NIHR)
This review of 13 studies showed that involving new mothers in group exercise programmes, or advising them on an exercise of their choice, reduced depressive symptoms compared with usual care. The effect was moderate but significant. Examples of exercise were pram walks, with dietary advice from peers in some studies. The benefits were shown whether or not the mothers had postnatal depression.
The NIHR reports that the evidence does have some limitations regarding its quality but is the best research currently available. This review should give additional confidence to health visitors and GPs to advise women that keeping active after birth can benefit their mental and physical health.
