Relationship between complementary and alternative medicine use and incidence of adverse birth outcomes: An examination of a nationally representative sample of 1835 Australian women

Use of complementary and alternative medicine in pregnancy and labour pain: a cross-sectional study from turkey

Background

This study aimed to determine the prevalence and pattern of complementary and alternative medicine (CAM) use by and attitudes towards CAM of Turkish women during pregnancy and birth.

Methods

This was a descriptive, cross-sectional study that included 260 women who gave birth in a university hospital. The Personal Information Form and Complementary, Alternative and Conventional Medicine Attitudes Scale (CACMAS) were used as data collection tools.

Results

A total of 71.5% of the pregnant women received CAM. Phytotherapy, spiritual meditation and therapeutic touch techniques were the most frequently used techniques. A total of 42.7% women used herbal products. The mean score of the women on the CACMAS scale was 108.37 ± 7.71; this result indicates that pregnant women had a positive attitude. There were significant differences in attitudes according to marital status, education level and place of residence. It was determined that there was a significant difference in the CACMAS scores of the women according to the symptoms experienced during pregnancy, CAM use during pregnancy and the concerns about triggering preterm birth by using CAM methods (p < 0.05).

Conclusion

Although the women commonly used CAM methods during pregnancy, the rate of using these methods during birth considerably decreased. Despite such widespread use, pregnant women have concerns about CAM methods. Therefore, health professionals must actively provide counselling on CAM methods for the protection of maternal and infant health.

A taxonomy of risk-associated alternative health practices: A Delphi study

Defining alternative health care and the recording of associated adverse events and harm remains problematic. This Canadian study aimed to establish and classify risk-associated alternative health practices in a Delphi study undertaken with an interdisciplinary panel of 17 health experts in 2020. It provides a new functional definition of alternative health care and an initial taxonomy of risk-associated alternative health care practices. A number of risk-associated practices were identified and categorized into general practices that conflict with biomedical care or largely untested therapies, alternative beliefs systems, physical manipulative alternative therapies, and herbal and nutritional supplements. Some risk significant harms including major physical injuries or even death. The lack of systematic methods for recording adverse events in alternative health care makes establishing the frequency of such events challenging. However, it is important that people engaging with alternative health care understand they are not necessarily risk-free endeavours, and what those risks are.

Low-Intensity Exercise and Pregnancy Outcomes: An Examination in the Nurses' Health Study II

Background: The benefit of low-intensity exercise (LIE) during pregnancy is poorly understood at a time when few women participate in moderate or vigorous exercise. Using data from the Nurses' Health Study II (NHSII), we tested the hypothesis that women who engaged in more LIE before and during pregnancy experience fewer pregnancy complications.

Methods: Among 116,429 U.S. female registered nurses (25–42 years of age) who were enrolled in NHSII in 1989, we included participants (36–50 years of age) who reported in 2001 or 2005 that they were pregnant and completed questionnaires about pregnancy “low-intensity exercise (yoga, stretching, toning),” and who in 2009, provided a full pregnancy outcome history. Multivariable-adjusted relative risk (RR) and 95% confidence intervals (CIs) were calculated between LIE and adverse pregnancy outcomes using log-binomial regression models.

Results: Among 225 eligible pregnant participants, 71 (31.6%) reported engaging in any LIE. LIE was associated with lower preterm birth, but not significantly associated with pregnancy loss or other adverse pregnancy outcomes. The RR for any LIE for preterm birth was 0.31 (95% CI: 0.09–1.07), with a significant dose–response association [RR = 0.65 (95% CI: 0.48–0.89) per every 30-minute session]. Some suggestive inverse associations were also observed for other adverse pregnancy outcomes: the RR for any LIE for low birthweight was 0.35 (95% CI: 0.08–1.48); for preeclampsia/gestational hypertension was 0.51 (95% CI: 0.13–1.96); and for gestational diabetes was 0.64 (95% CI: 0.25–1.64).

Conclusion: Pregnant women can include yoga, stretching, and toning exercise for promoting wellbeing.

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.

The effectiveness and characteristics of pregnancy yoga interventions: a systematic review protocol

Background: The purpose of this review is to systematically examine the reported clinical effectiveness of pregnancy yoga.  The review will use the FITT (frequency, intensity, time/duration and type) principle of physical activity to characterise the different types of yoga interventions that have been evaluated in the included studies.  Studies will be categorised as effectiveness or efficacy studies and this continuum of efficacy versus effectiveness will be incorporated into the full review.  Methods/design: The following electronic databases will be searched using a detailed search strategy: MEDLINE, PsycINFO, EMBASE, CINAHL, WHOLiS, AMED, ScieLo, ASSIA and Web of Science. Randomised control trials and quasi-experimental studies examining pregnancy yoga and reporting on effect will be included. Titles, abstracts and full articles will be screened by two investigators independently to identify eligible studies.  The Cochrane Collaboration's Risk of Bias Assessment tool will be used to assess study quality.  Quality of the evidence will be evaluated using the GRADE criteria. A standardised data extraction form will be used to extract data. Effect sizes will be estimated using mean differences for continuous outcomes, and relative risks for dichotomous outcome. Where possible, pooling of effect estimates will be done using a random effect model.  The outcomes of interest are quality of life, stress, anxiety, depression, mode of birth, labour duration and pain management in labour. Discussion: This review will synthesise the best available evidence on the effectiveness of yoga during pregnancy and provide valuable high-quality information for clinicians and health policymakers. Findings will be disseminated through publication in a peer-reviewed journal and presentation at relevant conference proceedings. The review will make recommendations for the appropriate volume, intensity and type of pregnancy yoga for maximum effect and may have implications for policy and practice relating to pregnancy yoga as an intervention.   Registration: PROSPERO, CRD42019119916.  Registered on 11th January 2019.

At-risk advertising by Australian chiropractors and physiotherapists

Background

Society expects professionals to promote their businesses in an ethical manner, refraining from misleading or deceptive marketing due to the potential to harm members of the community. In Australia this expectation resides in the Australian registration board advertising guidelines or the Health Practitioner Regulation National Law. Registration board data indicate there are many health care professionals failing to meet these expectations. The aims of this research were to determine the frequency, type and nature of at-risk advertising by Australian chiropractors and physiotherapists and whether there is a correlation between professional association membership and advertising guideline compliance.

Method

A cross sectional audit examining practitioner advertising was performed on representative samples of Australian chiropractors and physiotherapists. Two auditors examined advertising by 380 physiotherapists and 359 chiropractors for material potentially in breach of the regulatory authorities' advertising guidelines. The advertising appeared on practitioner websites and linked Facebook pages.

Results

Two-hundred and fifty-eight (72%) audited chiropractors and 231 (61%) audited physiotherapists had breaches of the Advertising Guidelines on their websites and linked Facebook pages. The frequency of breaches by chiropractors was higher. The type and nature of the breaches by chiropractors was potentially more harmful. Membership in a professional association influenced neither the frequency nor the severity of breaches with chiropractors.

Discussion

Advertising breaches were common in both samples even though regulators and professional associations provide practitioners with explicit information on how to comply with advertising guidelines. Breaches by chiropractors were more numerous and more serious due to their greater potential to lead consumers to make inappropriate and potentially harmful healthcare decisions.Stronger enforcement strategies may have a positive effect on compliance.

Pregnancy, prescription medicines and the potential risk of herb-drug interactions: a cross-sectional survey

Background

Pregnant women are routinely prescribed medicines while self-medicating with herbal natural products to treat predominantly pregnancy related conditions. The aim of this study was to assess the potential for herb-drug interactions (HDIs) in pregnant women and to explore possible herb-drug interactions and their potential clinical significance.

Methods

A cross-sectional survey of women during early pregnancy or immediately postpartum in North-East Scotland. Outcome measures included; Prescription medicines use excluding vitamins and potential HDIs assessed using Natural Medicines Comprehensive Database.

Results

The survey was completed by 889 respondents (73% response rate). 45.3% (403) reported the use of at least one prescription medicine, excluding vitamins. Of those taking prescription medicines, 44.9% (181) also reported concurrent use of at least one HNP (Range 1–12). A total of 91 different prescription medicines were reported by respondents using HNPs. Of those taking prescription medicines, 44.9% (181) also reported concurrent use of at least one HNP (Range 1–12). Thirty-four herb-drug interactions were identified in 23 (12.7%) women with the potential to increase the risk of postpartum haemorrhage, alter maternal haemodynamics, and enhance maternal/fetal CNS depression.

Almost all were rated as moderate (93.9%), one as a potentially major (ginger and nifedipine) and only one minor (ondansetron and chamomile).

Conclusion

Almost half of pregnant women in this study were prescribed medicines excluding vitamins and minerals and almost half of these used HNPs. Potential moderate to severe HDIs were identified in an eighth of the study cohort. Healthcare professionals should be aware that the concurrent use of HNPs and prescription medicines during pregnancy is common and carries potential risks.

A pilot randomised controlled trial exploring the effects of antenatal reflexology on labour outcomes

OBJECTIVE

to investigate the effects of antenatal reflexology on labour outcomes.

DESIGN

secondary analysis of a pilot three-armed randomised controlled trial conducted between July 2012 and September 2013.

SETTING

a large UK inner city hospital maternity department.

PARTICIPANTS

ninety primiparous women with a singleton pregnancy experiencing low back and / or pelvic girdle pain.

INTERVENTIONS

six weekly 30-minute reflexology treatments compared to sham (footbath) treatments or usual antenatal care only.

MEASUREMENTS

labour outcome data including labour onset, duration of the second stage of labour, epidural and Entonox usage, and mode of delivery. Participant feedback was collected prior to each treatment.

FINDINGS

labour outcomes were collected for 61 women (95.3%) who completed the study. The second stage of labour duration data, available for 42 women (62.5%) who had vaginal births, showed a mean reduction of 44minutes in the reflexology group (73.56minutes; SD= 53.78) compared to the usual care (117.92minutes; SD=56.15) (p<0.05) and footbath groups (117.4minutes; SD=68.54) (p=0.08). No adverse effects were reported.

KEY CONCLUSIONS

in this trial antenatal reflexology reduced labour duration for primiparous women who had experienced low back and/ or pelvic girdle pain during their pregnancy, compared with usual care and footbaths.

IMPLICATIONS FOR PRACTICE

reflexology is suitable for use during pregnancy, is safe and enjoyable and may reduce labour duration. Midwives may wish to recommend reflexology to promote normal childbirth and facilitate women centred care.

TRIAL REGISTRATION

this trial was listed with the International Standard Randomised Controlled Trial Number Register (ISRCTN26607527).

Substantial out-of-pocket expenditure on maternity care practitioner consultations and treatments during pregnancy: estimates from a nationally-representative sample of pregnant women in Australia

Background

A wide range of health care options are utilised by pregnant women in Australia. The out-of-pocket costs of maternity care in Australia vary depending on many factors including model of care utilised, health insurance coverage, and women’s decision to access health services outside of conventional maternity care provision.

Methods

Women from the 1973–78 cohort of the Australian Longitudinal Study on Women’s Health (ALSWH) who identified as pregnant or as recently having given birth in 2009 were invited to complete a sub-study questionnaire investigating health service utilisation during their most recent pregnancy.

Results

A total of 1,835 women agreed to participate in the sub-study. The majority of women (99.8%) consulted with a conventional health care practitioner during pregnancy, 49.4% consulted with a complementary and alternative medicine practitioner at least once during pregnancy and 89.6% of the women used a complementary and alternative medicine product. Women reported an average of AUD$781.10 in out-of-pocket expenses for consultations with conventional health care practitioners, AUD$185.40 in out-of-pocket expenses for consultations with complementary and alternative medicine practitioners and AUD$179.60 in out-of-pocket expenses for complementary and alternative medicine products. From the study data we estimate Australian pregnant women spend over AUD$337 M on out-of-pocket health services.

Conclusion

While the majority of pregnant women in Australia may obtain health services via the publically-funded health care system and/or private health insurance coverage, our analysis identifies substantial out-of-pocket expenditure for health care by pregnant women – a trend in public spending for maternity care of importance to policy makers, health administrators, and health professionals.

Effects of prenatal yoga on women's stress and immune function across pregnancy: A randomized controlled trial

OBJECTIVE

The effects of prenatal yoga on biological indicators have not been widely studied. Thus, we compared changes in stress and immunity salivary biomarkers from 16 to 36 weeks' gestation between women receiving prenatal yoga and those receiving routine prenatal care.

DESIGN

For this longitudinal, prospective, randomized controlled trial, we recruited 94 healthy pregnant women at 16 weeks' gestation through convenience sampling from a prenatal clinic in Taipei. Participants were randomly assigned to intervention (n=48) or control (n=46) groups using Clinstat block randomization.

INTERVENTION

The 20-week intervention comprised two weekly 70-min yoga sessions led by a midwife certified as a yoga instructor; the control group received only routine prenatal care.

MAIN OUTCOME MEASURES

In both groups, participants' salivary cortisol and immunoglobulin A levels were collected before and after yoga every 4 weeks from 16 to 36 weeks' gestation.

RESULTS

The intervention group had lower salivary cortisol (p<0.001) and higher immunoglobulin A (p<0.001) levels immediately after yoga than the control group. Specifically, the intervention group had significantly higher long-term salivary immunoglobulin A levels than the control group (p=0.018), and infants born to women in the intervention group weighed more than those born to the control group (p<0.001).

CONCLUSION

Prenatal yoga significantly reduced pregnant women's stress and enhanced their immune function. Clinicians should learn the mechanisms of yoga and its effects on pregnant women. Our findings can guide clinicians to help pregnant women alleviate their stress and enhance their immune function.

The Association between Prenatal Yoga and the Administration of Ritodrine Hydrochloride during Pregnancy: An Adjunct Study of the Japan Environment and Children's Study

Introduction

While the beneficial effects of prenatal yoga have been reported in recent years, little is known about its effectiveness in pregnant Japanese women. Despite several adverse effects, ritodrine hydrochloride is frequently prescribed to suppress preterm labor in Japan, and its usage may therefore indicate cases of preterm labor. This study aimed to clarify the association between prenatal yoga and ritodrine hydrochloride use during pregnancy.

Methods

An observational study was conducted as an adjunct study by the Hokkaido unit of the Japan Environment and Children’s Study. Information on prenatal yoga practice was collected using a self-questionnaire between March 21, 2012, and July 7, 2015, targeting women who had recently delivered. Ritodrine hydrochloride use was identified from medical records. A total of 2,692 women were analyzed using logistic regression models that adjusted for possible confounders.

Results

There were 567 (21.1%) women who practiced prenatal yoga, which was associated with a lower risk of ritodrine hydrochloride use (adjusted odds ratio [OR] 0.77; 95% CI 0.61–0.98). This was especially evident in women with a total practice duration that exceeded 900 minutes throughout their pregnancy (adjusted OR 0.54; 95% CI 0.38–0.76). A sensitivity analysis that excluded patients with threatened abortion during the study period produced similar results.

Conclusions

Prenatal yoga was associated with a lower risk of ritodrine hydrochloride use, particularly in women with more than 900 minutes of practice time over the course of their pregnancy. Prenatal yoga may be a beneficial option for pregnant women in the selection of alternative therapies.

Birth ball or heat therapy? A randomized controlled trial to compare the effectiveness of birth ball usage with sacrum-perineal heat therapy in labor pain management

OBJECTIVE

Labor pain and its management is a major concern for childbearing women, their families and health care providers. This study aimed to investigate the effects of two non-pharmacological methods such as birth ball and heat therapy on labor pain relief.

MATERIAL & METHODS

This randomized control trial was undertaken on 90 primiparous women aged 18-35 years old who were randomly assigned to two intervention (birth ball and heat) and control groups. The pain score was recorded by using Visual Analogue Scale (VAS) before the intervention and every 30 min in three groups until cervical dilatation reached 8 cm.

RESULTS

The mean pain severity score in the heat therapy group was less than that of in control group at 60 and 90 min after intervention (p < 0.05). In addition there were significantly differences between the pain scores in the birth ball group after all three investigated times in comparison to control group.

CONCLUSION

Both heat therapy and birth ball can use as inexpensive complementary and low risk treatment for labor pain.

Complementary and Alternative Medicine Use Among Women During Pregnancy and Childbearing Years

OBJECTIVES

Little is known regarding complementary and alternative medicine (CAM) use during pregnancy and the preconception period. Since half of all pregnancies in the United States are unintended, understanding the patterns of CAM use among women of childbearing age has implications for fetal and maternal health.

METHODS

Descriptive statistics were generated from the 2012 National Health Interview Study (NHIS) to estimate weighted prevalence and patterns of CAM use by women of childbearing age. Comparisons were made between pregnant and nonpregnant respondents.

RESULTS

In this sample of 10,002 women, 7 percent (n = 727) were recently pregnant. Over one-third of all the women used CAM during the previous year (34/38%, pregnant/nonpregnant, respectively) and only half disclosed CAM use to conventional providers (50/49%). In the adjusted model, taking multivitamins (OR 2.52 [CI 2.22-2.86]) and moderate to heavy alcohol use (OR 1.92 [CI 1.53-2.41]) were more likely associated with CAM use. The two most commonly used modalities were herbs (14/17%) and yoga (13/16%). The top reasons for CAM use were to improve general wellness or to prevent disease (33/35%) and to treat back pain (16/18%). When examining all pregnancy-related symptoms treated with CAM, no difference was found in the rates of CAM use between pregnant and nonpregnant users.

CONCLUSIONS

CAM use by women of childbearing age in the United States is common, with over a third of the population using one or more therapies. However, only half disclosed their use to conventional providers despite limited evidence on safety and effectiveness. This study highlights the important need for further research in this area.

Characteristics of women who practice yoga in different locations during pregnancy

OBJECTIVES

Yoga practice during pregnancy is gaining increasing popularity. This study examined the characteristics of pregnant women who practiced yoga in regard to the different locations (at home, in yoga classes, or both).

DESIGN

The study sample was drawn from the Australian Longitudinal Study on Women's Health (ALSWH), a national longitudinal study of women to investigate multiple factors affecting health and well-being of women over a 20-year period.

SETTING

Postal survey.

PARTICIPANTS

Women born between 1973 and 1978, who were randomly selected from the national Medicare database and identified as being pregnant or having recently given birth (n=2316).

OUTCOME MEASURES

Relationships between yoga use (attending yoga classes and/or practising yoga at home) and women's characteristics (demographic measures, pregnancy-related health concerns, health service utilisation, attitudes to complementary and alternative medicine).

RESULTS

Practising yoga both at home and in classes was associated with perceiving complementary and alternative medicine (CAM) as preventative (odds ratio (OR)=1.62); perceiving CAM as affording health control (OR=1.50); experiencing sadness (OR=1.72); preparing for labour (OR=2.31); birthing in a birth centre (OR=7.97); and experiencing less vomiting (OR=0.38). Practising at home only was associated with perceiving CAM as affording health control (OR=1.76); perceiving CAM as promoting a holistic health approach (OR=1.65); and birthing in a birth centre (OR=3.54). Practising in classes only was associated with experiencing stress (OR=1.97); and birthing in a birth centre (OR=4.85) (all p<0.05).

CONCLUSIONS

The findings suggest that the location in which a woman practices yoga is associated with attitudinal, health-related and birth environmental factors.

Determinants of use of care provided by complementary and alternative health care practitioners to pregnant women in primary midwifery care: a prospective cohort study

BACKGROUND

Pregnant women visit complementary/alternative health care practitioners in addition to regular maternal health care practitioners. A wide variation has been reported with regard to rates and determinants of use of complementary/alternative medicine (CAM), which may be due to heterogeneous populations. The aim of this study was to examine the prevalence and determinants of use of CAM practitioners by a homogeneous population of low-risk pregnant women in the Netherlands.

METHODS

Data from the population-based DELIVER study was used, concerning 1500 clients from twenty midwifery practices across the Netherlands in 2009 and 2010. CAM use was measured based on patient reports. Potential determinants were derived from Andersen's behavioural model of health care utilization.

RESULTS

The prevalence of CAM practitioner use by low-risk pregnant women was 9.4 %. Women were more likely to use CAM if they had supplementary health care insurance (OR 3.11; CI 1.41-6.85), rated their health as 'bad/fair' (OR 2.63; CI 1.65-4.21), reported a chronic illness or handicap (OR 1.93; CI 1.14-3.27), smoked during pregnancy (OR 1.88; CI 1.06-3.33), or used alcohol during pregnancy (OR 2.30; CI 1.46-3.63).

CONCLUSIONS

CAM is relatively frequently used by low-risk pregnant women. Determinants revealed in this study diverge from other studies using heterogeneous populations. Maternal health care practitioners must be aware of CAM use by low-risk pregnant women and incorporate this knowledge into daily practice by actively discussing this subject with pregnant women.

The Outcomes of Complementary and Alternative Medicine Use among Pregnant and Birthing Women: Current Trends and Future Directions

Complementary and alternative medicine is used by a substantial number of pregnant women and maternity care providers are often faced with the task of ensuring women are using safe and effective treatments while respecting a woman's right to autonomous decision-making. In the era of evidence-based medicine maternity health professionals are expected to draw upon the best available evidence when making clinical decisions and providing health advice. This review will outline the current trends in research evidence associated with the outcomes of complementary and alternative medicine use amongst pregnant and birthing women as well as highlight some potential directions for future development in this important yet largely unknown topic in contemporary maternity care.
