SUMMARY
Given high levels of interest in CHPs during the perinatal period, there is a need for research addressing acceptability, safety, and efficacy of these interventions. Large-scale surveys suggest many perinatal women already seek out CHP for potential health benefits, even in the absence of clear safety and efficacy data, and a substantial subset of perinatal women report that their prenatal care providers do not ask about their use of CHPs.89 As such, it is important for providers to routinely inquire about patients’ interest in and use of CHPs, and additional research is needed to provide clear data to guide decisions about which products and practices are helpful and safe. With a vast array of CHPs, we did not attempt to review evidence for all products or interventions. We examined data regarding some of the most commonly used CHPs, including various natural products and vitamins and popular mind and body approaches. Until subsequent research is conducted and questions answered, our review has found encouraging preliminary evidence supporting efficacy of O-3FA, folate, vitamin D (in cases of deficiency), physical activity interventions, and prenatal/postpartum yoga for reducing or preventing PND symptoms. However, some approaches have only been examined during pregnancy, and others only in the postpartum.
