Factors influencing women's decision-making regarding complementary medicine product use in pregnancy and lactation

Investigating Pregnant Women's Attitudes toward Herbal Remedies: A Cross-Sectional Study

BACKGROUND

Herbal remedies play a significant role in daily life, regardless of region or ethnicity. While they offer various health benefits, they may also pose risks, including toxicity and undesirable side effects. Pregnant women, one of the most vulnerable populations, frequently use herbal remedies, often without informing their healthcare providers, which can lead to unforeseen consequences for both the mother and the fetus.

METHOD

A total of 590 women participated in an online survey designed to assess demographic factors, awareness of herbal remedies during pregnancy, and the potential impact of these remedies on maternal and fetal health.

RESULTS

The survey revealed that 35.8% of the participants used herbal remedies during pregnancy. The most common reasons for their use were beliefs in their safety and family recommendations. Anise (Pimpinella anisum L.) was the most frequently used herb.

CONCLUSIONS

The findings indicate that pregnant women generally have limited knowledge about herbal remedies and their potential risks. To mitigate this, it is essential to develop and disseminate comprehensive safety and efficacy guidelines. Both physicians and pregnant women should be well-informed to ensure the protection of maternal and fetal health.

A Qualitative Study of Breastfeeding Experiences Among Mothers Who Used Galactagogues to Increase Their Milk Supply

OBJECTIVE

To qualitatively describe breastfeeding experiences among mothers who used galactagogues to increase their milk supply.

DESIGN

One-time, semistructured phone interviews.

SETTING

US.

PARTICIPANTS

Breastfeeding mothers (n = 19) who reported ever consuming foods, beverages, or herbal supplements to increase their milk supply in a cross-sectional online survey were purposefully sampled to participate in this qualitative study. Participants were diverse in terms of race and ethnicity, education, income, infant age (0-18 months), and prior breastfeeding experience (32% first-time breastfeeding).

PHENOMENON OF INTEREST

Reasons for trying to increase milk supply, sources of information about increasing milk supply, and strategies tried to increase milk supply.

ANALYSIS

Interviews were transcribed verbatim and analyzed using reflexive thematic analysis.

RESULTS

Participants expressed determination and commitment to breastfeeding but unexpectedly struggled to breastfeed and increase their milk supply. They sought information from multiple sources and used individualized approaches to address milk supply concerns on the basis of recommendations from others, as well as the perceived convenience, cost, palatability, and safety of potential strategies.

CONCLUSIONS AND IMPLICATIONS

Results suggest a need to expand breastfeeding education and support so that lactating parents anticipate common breastfeeding challenges and are aware of evidence-based strategies for increasing their milk supply.

Complementary and alternative medicine use by pregnant women in Japan: a pilot survey

BACKGROUND

Complementary and alternative medicine (CAM) are popular among women, and are used during their pregnancy in Japan. This study aimed to survey the prevalence of CAM use by healthy pregnant women as a health-care prescribed therapy or self-care and to investigate the factors associated with CAM use in Japan.

METHODS

In this cross-sectional study, pregnant women after 34 weeks of gestation were asked to respond to a questionnaire at the clinic or online. The questionnaire comprised questions on the participants' characteristics and their use of CAM for therapy and self-care. Descriptive statistics were calculated in the analyses, and bivariate and multivariate logistic analyses were performed to evaluate the associations between factors and CAM use.

RESULTS

A total of 394 women responded from three hospitals, two clinics, and two midwifery birth centers. CAM was received as treatment by practitioners during pregnancy by 75 women (19.0%). The following therapies were used: traditional Chinese medicine (7.9%), chiropractic (6.9%), moxibustion (6.4%), and acupuncture (5.3%). One or more types of therapy were used as self-care by 348 women (88.3%). Highly used CAM for self-care were: folic acid supplementation (75.4%), other supplements (51.5%), herbs (20.8%), and yoga (19.0%). Multiple logistic regression analyses revealed that the factors associated with CAM use as a therapy were midwifery birth centers for planned childbirth settings (adjusted odds ratio [AOR] 3.64, 95% confidence interval [CI] [1.69-7.83]) and pregnancy complications diagnosed (AOR 2.46, 95%CI [1.38-4.39]). The factors associated with CAM use for self-care were age 30-39 years (AOR 4.48, 95%CI [2.14-9.73]) and over 40 years (AOR 3.92, 95%CI [1.10-13.91]), junior college education or above (AOR 2.30, 95%CI [1.18-4.51]), and primiparas (AOR 3.82, 95%CI [1.86-7.86]). The most common source of information was the "Internet" (43.8%).

CONCLUSIONS

Approximately 20% of Japanese pregnant women received CAM as therapy by practitioners, and the related factors were: tended to have baby at midwifery birth center and pregnancy complications. Almost 90% of respondents used CAM as self-care and the related factors were: older, had a higher educational level and tended to be primiparas. They used the Internet as their main source of information about CAM. Health care providers need to provide evidenced-based information on CAM and to help decision making to ensure safe and effective CAM utilization by pregnant women.

Attitudes pregnant women in Türkiye towards holistic complementary and alternative medicine and influencing factors: a web-based cross-sectional study

BACKGROUND

Pregnant women turn to holistic complementary and alternative medicine to cope with problems associated with the changes they experience during pregnancy. This study aimed to determine the attitudes of pregnant women in Türkiye toward holistic complementary and alternative medicine and influencing factors.

METHODS

This cross-sectional exploratory study was carried out between June and November 2022 with a web-based questionnaire distributed via social media and communication platforms. Two hundred and twenty-one pregnant women participated in the study. A "Participant Identification Form" and the "Attitudes towards Holistic Complementary and Alternative Medicine Questionnaire" were used to collect the data. Logistic regression analysis was used to determine correlations between variables and scale scores.

RESULTS

It was determined that 84.2% of the participants had knowledge about traditional and complementary therapies, and 77.8% used traditional and complementary therapies. The participants reported that they preferred faith (77.4%), energy healing (76.9%), massage (75.6%), diet (74.2%), meditation/yoga (62.0%), and herbal (59.7%) traditional and complementary therapies the most, and most of them used these methods to reduce nausea, vomiting, edema, and fatigue during pregnancy. The mean Attitudes towards Holistic Complementary and Alternative Medicine Questionnaire score of the participants was 35.0 (5.04). It was seen that having high school or higher education (p < 0.05), having an income more than expenses (p < 0.001), having received advice from nurses when having a complaint (p < 0.001), having knowledge about traditional and complementary therapies (p < 0.001), and being a practitioner who received services of traditional and complementary therapies (p < 0.001) were positively associated with the utilization of traditional and complementary therapies.

CONCLUSION

In this study, it was determined that the attitudes of pregnant women towards holistic complementary and alternative medicine were high. Their personal characteristics, as well as their knowledge and practice of holistic complementary and alternative medicine affected their attitudes towards holistic complementary and alternative medicine. Obstetrics nurses/midwives should actively participate in training programs on traditional and complementary therapies focused on pregnant women.

Correlates of higher anxiety scores reported by women admitted for elective caesarean section

Background

An elective caesarean section (CS) has been associated with high anxiety scores, and there are associations between higher anxiety scores and younger age, primigravidae, higher educational level, and previous experience with anaesthesia. In this study, the aim is to measure anxiety scores associated with an elective CS using two measuring scales and identify women's characteristics and obstetrics variables that are associated with higher scores.

Methods

A cross-sectional study was conducted between Nov 15, 2019 and Nov 15, 2020. Women were included if they were 18 years of age or more, had viable pregnancies, and were admitted for an elective CS. Anxiety scores were measured on admission using the visual analogue scale for anxiety (VASA) and then the State-Trait Anxiety Inventory (STAI-Y). Associated factors were studied using logistic regression analyses.

Results

Three hundred women were recruited. Means (SD) for the participant's age and gestation age were 30.5 (5.7) years and 37.6 (1.4) weeks, respectively. Additionally, 29.3% of the participants having a CS were primigravidae and 62.3% were for maternal indications. Furthermore, 55%, 59%, and 61% of the women had scores above the means of VASA and STAI-S components 1 and 2, respectively.Variables that showed statistically significant associations with higher anxiety scores were that the woman's age was 25-34, the CS was for foetal indications, the choice of anaesthesia was general, and the source of information for the choice of anaesthesia was a layperson.

Conclusion

Higher anxiety scores are prevalent among women admitted for an elective CS. STAI-Y and VASA correlated well, and the short VASA may replace the lengthy STAI-Y in clinical practice. Identification of women with risk factors may help in implementing strategies to reduce anxiety.

An integrative review on the maternal health literacy among maternal and child workers

AIMS

This study aim to capture the most comprehensive evidence-based dimensions of maternal health literacy, including summarizing the definitions, theoretical frameworks, measuring instruments, and the association between maternal health literacy and health behaviours.

BACKGROUND

Maternal health literacy has been recognized as an important approach to achieving high-quality maternal and child health; however, little is known about maternal health literacy comprehensively and scientifically.

EVALUATION

An integrative review retrieved articles from 11 databases, following the methodology of Whittemore and Knafl. Inductive content analysis and narrative synthesis were conducted, guided by the aim of this review.

KEY ISSUES

A total of 5580 articles were retrieved and 23 articles were finally identified. Existing definitions and theoretical frameworks took less consideration of maternal applicability and failed to summarize maternal health literacy from a dynamic and systematic perspective. Measurement instruments were set up with many items that make it difficult to quickly screen for poor maternal health literacy. Most articles proved the association between maternal health literacy and health behaviours through correlation analysis or regression analysis but less explored the influence pathways between them.

CONCLUSION

The definition and theoretical framework need to focus on maternal applicability and explain the process of individual mothers acquiring and understanding health knowledge and skills from a dynamic and systematic perspective. A rapid instrument for maternal health literacy should be developed and high-quality empirical research was conducted to understand the associated mechanisms between maternal health literacy and health behaviours.

IMPLICATIONS FOR NURSING MANAGEMENT

It is necessary to strengthen maternal and child health education of primary health care nurses and enhance their ability to help perinatal women use maternal and child health information effectively.

Women's reasons for taking complementary medicine products in pregnancy and lactation: Results from a national Australian survey

BACKGROUND

and purpose: Pregnant and breastfeeding women commonly use complementary medicine products (CMPs), including dietary supplements and herbal medicines. This study investigated women's reasons for use.

MATERIALS AND METHODS

A national, cross-sectional, online survey conducted between July-September 2019 investigated reasons for CMP use during pregnancy and lactation. Australian women who were currently pregnant and/or breastfeeding participated. Data analysis included descriptive statistics, Chi-square and principal component analyses.

RESULTS

Of the 810 women surveyed (n = 354 pregnant; n = 456 breastfeeding), most reported prior CMP use and felt that CMPs had been beneficial to maintaining and optimising their own and their children's health. However, when ill, they preferred medicines prescribed by doctors or pharmacists. Perceived benefits to their unborn or breastfeeding babies' health and their own health (both cohorts), the health of their pregnancy (pregnant participants), and benefits to the breastfeeding process and breastmilk supply (breastfeeding participants) were important reasons for women's CMP use.

CONCLUSION

Women's reasons for CMP use centred on perceived benefits to their own health and the health of their babies. Women's prior positive experiences with CMP use, combined with preferences for pharmaceutical use when ill, indicates their use of CMPs can be considered complementary, rather than alternative, to biomedical health care.

Food Supplement Use Differs from the Recommendations in Pregnant Women: A Multinational Survey

The aim was to investigate, among pregnant women, (1) the use of food supplements and (2) the awareness of food supplement recommendations and beliefs about food supplement use in four European countries: Finland, Italy, Poland, and the United Kingdom. The participants (n = 1804) completed an online questionnaire with predefined statements. Daily intakes of vitamins and minerals were calculated using uploaded pictures or weblinks of the supplement packages. Country differences were assessed. Most participants (91%) used at least one food supplement during pregnancy. A prenatal multivitamin was the most commonly used supplement type (84% of the users), and 75% of the participants thought consumption of multivitamin is recommended. Of the participants, 81% knew that folic acid is recommended during pregnancy while 58% knew the recommendation for vitamin D. In 19% of the supplement users, the daily safe upper intake limit of at least one nutrient was exceeded. Nevertheless, most participants agreed that they knew which supplements (91%) and doses of supplements (87%) needed to be used during pregnancy. To conclude, the majority of the participants used food supplements, but lower proportions knew and adhered to the recommended intakes. Between-country differences were observed in the use and knowledge of and beliefs regarding supplements. The results suggest a need for assessment and monitoring of supplement use in antenatal care to ensure appropriate use.

Expecting parents' use of digital sources in preparation for parenthood in a digitalised society - a systematic review

Background

In today's society, people are experiencing the rapid development of digitalisation. Expecting parents may have difficulties evaluating the information online; they are not always sure which sources of information are trustworthy, and this exacerbates their feelings of anxiety. More research is needed to broaden the knowledge about how their use of digital sources may influence their health.

Question

The focus of this study was to explore expecting parents' use of digital sources and how this influences their health during pregnancy.

Methods

A systematic review covered the thematic analysis of 39 articles.

Findings

The analysis resulted in the following theme: The digitalised society involves both opportunities and challenges, and expecting parents express a need for a variety of digital sources to improve their health, and sub-themes: Digital sources could promote parents' health and well-being in a digitalised society; Consuming digital health information facilitates understanding, different feelings and social connections; and A variety of digital sources may facilitate parental identification and adaption to parenthood.

Conclusion

Different digital sources in our digitalised society mean access to information and opportunities to extend social connections for expecting parents. This can promote their ability to understand and adapt to parenthood, as well as to improve their health and well-being and make the parental transition. However, professional support during face-to-face consultations cannot always be exchanged to digital sources. It is important to base digital sources devoted to expecting parents and digitalisation overall on multi-sectorial collaborations and coordination between different organisations and the digital sources they provide.

Enema Administration During Labor: Pregnant Women's Perspective and Knowledge

Introduction

Current evidence does not support the routine use of rectal enemas (REs) because they have not been associated with reduced rates of puerperal infection, degree of perineal tear, or duration of labor. A recent literature review recognized knowledge gaps regarding the uses of RE during labor including women's perceptions, pain, and satisfaction.

Objectives

To report pregnant women's knowledge, attitudes, perceptions, pain, and satisfaction associated with the use of RE during labor.

Methods

A prospective study was conducted between 20 October 2019 and 20 October 2020. Women were included if they were 37 weeks or more pregnant, had a viable pregnancy, were admitted in labor, and had an RE. Characteristic data and data about knowledge, perceptions, attitudes, pain, and satisfaction associated with its use were recorded. Women were regrouped based on their level of knowledge into low- and high-level groups. Attitudes, perceptions, inconveniences, pain, and satisfaction were regrouped into two categories: low and high on the Likert scale.

Results

A total of 300 women were recruited, with means (SD) for age and gestational age of 27.8 (4.8) years, and 40 (1.1) weeks, respectively, and 45.7% were knowledgeable or very knowledgeable, 76% had a positive attitude, and 88.7% perceived enemas as important. The mean scores (SD) for pain and satisfaction as measured on visual analogue scales were 1.5 (1.8) and 5.4 (1.8), respectively. Women with high knowledge about RE were older and multiparous. Recruited women were more likely to report lower inconvenience and pain scores and higher satisfaction scores (all P<.05).

Conclusion

Most recruited women were knowledgeable about REs, perceived them as important, and expressed a positive attitude toward their administration. The low levels of inconvenience, pain, and complications and the high satisfaction rates may be used when counseling women about when an RE is required during labor.

Sustainability in transformation of maternal mortality by interaction based approach in Dairi, Indonesia

Background

Health and mortality problems are closely related to the maternal mortality rate (MMR). Efforts to reduce MMR have been carried out by many countries, including the Indonesian government.

Design and Methods

This research was conducted using two approaches, namely quantitative and qualitative or mixed methods and 149 respondents and 26 informants, to reduce MMR in Dairi Regency. This study was also carried out to determine the dominant variable that affects mother's behavior in an effort to reduce MMR in accordance with the existing theory.

Result

Mother's intention to contribute to the reduction of MMR in this study was influenced by the good factor directly or indirectly. This is indicated by the score p<0.005. The study also shows that it is very important for the health workers to be able to communicate well with individuals and communities.

Conclusion

The present study will help to reduce maternal fatalities, and will help to build systems and processes that will allow control the behaviour of the pregnant women and determine the cause of death as well as its contributing factors.

Demographics, health literacy and health locus of control beliefs of Australian women who take complementary medicine products during pregnancy and breastfeeding: A cross-sectional, online, national survey

Background

Pregnant and breastfeeding women's use of complementary medicine products (CMPs) is common, and possibly associated with autonomous health care behaviours. However, the health literacy levels and health locus of control (HLOC) beliefs of women who use CMPs in pregnancy and lactation have not been previously assessed in a large Australian sample.

Aim

The aim of this study is to determine the health literacy levels and HLOC beliefs of women who use CMPs in pregnancy and lactation and determine the types of CMPs used.

Methods

A cross‐sectional, national, online survey of Australian pregnant or breastfeeding women aged 18 years and older, and currently using CMPs was conducted.

Results

A total of 810 completed surveys (354 pregnant and 456 breastfeeding women) were analysed. Most had adequate functional health literacy levels (93.3%). Health care practitioners (HCPs) HLOC mean scores were the highest for the sample, followed by Internal HLOC beliefs mean scores. Almost all (n = 809) took at least one dietary supplement, the most popular being pregnancy and breastfeeding multivitamins, iron supplements and probiotics. Use was generally in line with clinical recommendations, except for low rates of iodine supplementation. Herbal medicine use was lower for the total sample (57.3%, n = 464), but significantly higher (p < .0001) for the breastfeeding cohort, with consumers taking one to four herbal medicines each. The most popular herbs were raspberry leaf, ginger, peppermint and chamomile (pregnant respondents) and chamomile, ginger and fenugreek (breastfeeding respondents).

Conclusions

Respondents were health literate, with high scores for Internal and HCP HLOC scales, suggesting that they are likely to demonstrate self‐efficacy, positive health behaviours and work well in partnership with HCPs. HCPs can facilitate discussions with pregnant and breastfeeding women using CMPs, while considering women's health literacy levels, health beliefs and goals.

"Fear of stopping" vs "wanting to get off the medication": exploring women's experiences of using domperidone as a galactagogue - a qualitative study

Background

Domperidone is the most frequently prescribed medicine used to increase breast milk supply. There is considerable controversy surrounding the use of domperidone in lactation, due to limited evidence about efficacy and concerns about rare but life-threatening side-effects. Despite this, in many high-income settings such as Australia, use of domperidone among breastfeeding mothers appears to be increasing. The aim of this paper was to explore women’s experiences of using domperidone during breastfeeding.

Methods

Semi-structured interviews were conducted in 2019 with 15 women in Australia who reported using domperidone as a galactagogue during breastfeeding. Interviews were recorded, transcribed and analysed thematically.

Results

Women reported a wide variety of practices concerning the timing of initiation of domperidone use, including prophylactic use, as well as the dose and duration of use. Prolonged periods of use and unsupervised dosing were commonly reported, these practices were sometimes associated with a fear of the consequences of stopping, insufficient provision of information about the drug or feeling dismissed by health professionals. Some women indicated that when doctors refused to prescribe domperidone they responded by doctor shopping and seeking anecdotal information about benefits and risks online, leading to unsupervised practices. Women often reported high expectations surrounding the effectiveness of domperidone, and most used the medication in conjunction with food/herbal galactagogues and non-galactagogue support. Positive outcomes following domperidone use included having greater confidence in breastfeeding and pride at achieving breastfeeding goals.

Conclusions

This study identified a variety of practices concerning domperidone use, including potentially unsafe practices, linked in some cases to inconsistent advice from health professionals and a reliance on online, anecdotal information sources. These findings emphasise the urgent need for development of clinical practice guidelines and a greater focus on translating existing evidence concerning domperidone into clinical practice, including clinical support that is tailored to women’s needs.

Digital Tools as Parental Support-A Study Protocol Describing Prospective Development and Exploration of Two Digital Tools for Parents

Background: The access to digital tools for parents is increasing, and further exploration is needed to gain knowledge about parents' experiences in using such tools, for example, when preparing for childbirth and parenthood. This study protocol describes a prospective study that will explore serious games as digital tools for parental support, and both parents' and healthcare professionals' views will be included. The objectives of the prospective study are to explore two different serious games: (1) Childbirth Journey (Swedish: Förlossningsresan), relating to pregnancy, childbirth and parenthood; and (2) Interplay (Swedish: Samspel), relating to parental couple relationships and parenthood. Methods: An intervention study will be conducted. The study will include four different sub-studies (A-D) with both qualitative and quantitative methods and a longitudinal design. Both parents (A, B and D) and healthcare professionals (C) will be included, and data will be collected through interviews (A-C) and repeated web-based questionnaires (D). Data will be analysed using phenomenography and qualitative content analysis (A-C), and descriptive and analytical analyses will be performed for comparisons and associations (D). Discussion: The value of monitoring and reporting on developments and trends in digital innovation for public health has been stipulated by the World Health Organization. The prospective study will contribute further knowledge about multidisciplinary development of digital tools as professional support for parents, as well as knowledge about parents' and healthcare professionals' experiences using digital tools concerning pregnancy, labour, parenthood and parental couple relationships. Trial Registration: This study was retrospectively registered (02/10/2020) within the ISRCTN with ID: ISRCTN18017741. http://www.isrctn.com/ISRCTN18017741.

Perceived Social Influences on Women's Decisions to use Medications not Studied in Pregnancy. A Qualitative Ethical Analysis of Preexposure Prophylaxis Implementation Research in Kenya

Implementation research ethics can be particularly challenging when pregnant women have been excluded from earlier clinical stages of research given greater uncertainty about safety and efficacy in pregnancy. The evaluation of human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) during pregnancy offered an opportunity to understand important ethical considerations and social influences shaping women's decisions to participate in the evaluation of PrEP and investigational drugs during pregnancy. We conducted interviews with women (n = 51), focus groups with male partners (five focus group discussions [FGDs]), interviews with health providers (n = 45), four FGDs with pregnant/postpartum adolescents and four FGDs with young women. Data were analyzed using thematic content analysis, including ethical aspects of the data. Our study reveals that women navigate a complex network of social influences, expectations, support, and gender roles, not only with male partners, but also with clinicians, family, and friends when making decisions about PrEP or other drugs that lack complete safety data during pregnancy.

The risk-risk trade-offs: Understanding factors that influence women's decision to use substances to boost breast milk supply

Galactagogues are foods, herbs or medications thought to support or increase breast milk supply. The use of galactagogues during lactation is becoming increasingly common despite limited evidence regarding effectiveness and safety, and no definitive recommendations for use in clinical practice. The aim of this study is to explore factors influencing women's decisions to use galactagogues during lactation. Twenty-two semi-structured interviews were conducted in October and November 2019 (over the telephone or in person) with participants located in most Australian states and territories, including metro and regional areas. Interviews were audio-recorded, transcribed verbatim and thematically analysed using NVivo. Analysis revealed that following a concern about breast milk supply, the decision to use galactagogues was influenced by three core and interrelated domains: access to and quality of breastfeeding support, maternal agency and determination to provide breast milk. Women revealed many problematic experiences with health care professionals that left them feeling dismissed and confused due to provision of inconsistent and insufficient information that was sometimes at odds with their desire to provide breast milk. In this instance, some women turned to galactagogues to regain agency. A range of broader dimensions influencing decision-making also emerged. These were separated into categories that emphasise distinctions relating to breast milk supply, which included: maternal emotional wellbeing, social norms and pressures, concerns about infant development, maternal physical health and lactation history, as well as those relating specifically to galactagogue use, including: desire for a guaranteed/urgent response, risk-risk trade-off, acceptance and trust, and accessibility and cost. In understanding the complexity of decision-making concerning these substances, we identify opportunities to improve breastfeeding counselling and support. We recommend that support be individually tailored to manage conflicting information, adopt communication styles that encourage trust and processes that enable shared decision-making to enhance or restore maternal agency. There is also considerable need to address evidence gaps regarding the effectiveness and safety of commonly used galactagogues, so that women can be appropriately counselled about potential benefits and harms.

The effect of probiotic supplementation during pregnancy on the interaction network of vaginal microbiome

AIM

To evaluate the effect of probiotic supplementation on the vaginal microbiome and provide the effective evidences for clinical management of pregnant women.

METHODS

A total of 28 healthy pregnant women at 32 weeks of gestation were enrolled. The women were divided randomly to the probiotic group where they were prescribed with 2 g combined probiotics daily (13 cases) during the third trimester of pregnancy or to the control group (15 cases) on a voluntary basis. Their vaginal samples were taken for analyzing microbiome with the 16S rDNA amplicon sequencing of V4 region.

RESULTS

There was no significant difference on the clinical characteristics between the probiotic and control groups. The complexity of vaginal microbial network increased from 32 weeks of gestation to antepartum. Lactobacillus was the dominant microbiota. The probiotic supplementation had no obvious influence on the structure of the vaginal microbiome, whereas the relationships of some pivotal vaginal microbiota at the genus level changed in the probiotic group.

CONCLUSION

The vaginal microbiome varied during the third trimester of pregnancy. The features of the vaginal microbiota after probiotic supplementation had shifted and the interaction network had the tendency to be loose. The probiotic supplementation may be useful in regulating the interaction network of vaginal microbiome.

Using Facebook to recruit to a national online survey investigating complementary medicine product use in pregnancy and lactation: A case study of method

BACKGROUND

Online recruitment can be targeted efficiently to recruit specific samples for survey research. It has been shown to be a cost-effective method of recruitment, and useful for geographically dispersed populations.

OBJECTIVES

To describe the use of Facebook to recruit a targeted sample of expectant and breastfeeding mothers to a national online survey. Different techniques to assess response rates using data provided by Facebook are also described.

METHODS

Participants accessed an anonymous online survey through a link included in posts from a Facebook page specifically set up for the research. Recruitment strategies were primarily of two types. Firstly, Facebook was paid to promote posts by displaying them on potential participants' Facebook feeds. Secondly, by purposive and snowball recruitment through the sharing of posts on relevant Facebook pages. Post success was measured by the reach, impressions, link clicks, post clicks, and click through rates; and for boosted posts, the cost per day, and cost per engagement with the post as well. Traditional methods of calculating response rates, and response rates using post clicks and survey link clicks were calculated.

RESULTS

After 10 weeks of recruitment, 1418 participants had enrolled in the study, and of these 810 (57.1%) completed the 20-minute (70 question) survey. Women participated from across Australia. Both paid and purposive approaches to promotion contributed to recruitment success. Paid promotions at higher costs for fewer days were the most successful. Total paid promotion costs were (Australian) $1147.97 (or $1.44 per completed survey). Purposive promotion was slower, but also contributed significantly to the number of people who saw the posts and clicked through to the survey. Traditional response rate calculations showed a response rate of 0.8%. Using post clicks and survey link clicks in calculations, resulted in response rates of 23.1% and 42.7%, respectively.

CONCLUSIONS

A combination of paid promotions and purposive and snowball recruitment on Facebook were used to successfully recruit 1418 participants resulting in 810 completed surveys over a 10-week period, at a low cost per participant. Use of additional methods to measure response rates may be useful in measuring the success of using Facebook posts in recruitment.
