The outcome of complementary and alternative medicine use among pregnant women in South-East Nigeria: a multi-centre prospective study

There is a global increasing trend of complementary and alternative medicine (CAM) use among pregnant women. This study aimed at determining the maternal and perinatal outcome of CAM use among the pregnant women in South-East Nigeria. This was a prospective study in which self-administered semi-structured questionnaires were used to collate information from the consenting pregnant women who use CAM and those who did not use CAM from the gestational age of 36 weeks at four hospitals in South-East Nigeria. Both groups were matched for age, parity and address. Every participant was followed up until delivery. Data were analysed using SPSS version 23 (SPSS Inc., Chicago, IL). This study's ethical clearance number was NHREC/05/01/2008B-FWA00002458-1RB00002323 and it was obtained at UNTH and on February 15 2019. CAM use in pregnancy was associated with low haemoglobin concentration, maternal complications, high caesarean section rate, low birth weight, low APGAR score, large placental weight and high hospital admission of babies when compared with non-CAM users (p value= <.05). In conclusion, CAM use in pregnancy was associated with poor maternal and perinatal health indices, hence the need to implement policies aimed at reversing them.Impact StatementWhat is already known on this subject? There is an increasing trend of CAM use among pregnant women in the world. Pregnancy is associated with certain conditions that predispose women to CAM use. The clinical indications for CAM use by the pregnant women are nausea and vomiting, labour pain, induction of labour, pedal oedema and waist pain.What the results of this study add? CAM use in pregnancy was associated with low haemoglobin concentration, maternal complications, high caesarean section rate, low birth weight, low APGAR score, large placental weight and high hospital admission of the babies when compared with non-CAM users.What the implications are of these findings for clinical practice and/or further research? CAM use in pregnancy was associated with poor maternal and perinatal health indices, hence the need to implement policies aimed at reversing them.
