Development of the Conversational Health Literacy Assessment Tool for maternity care (CHAT-maternity-care): participatory action research.

BACKGROUND: Limited health literacy in (expectant) parents is associated with adverse health outcomes. Maternity care providers often experience difficulties assessing (expectant) parents' level of health literacy. The aim was to develop, evaluate, and iteratively adapt a conversational tool that supports maternity care providers in estimating (expectant) parents' health literacy. METHODS: In this participatory action research study, we developed a conversational tool for estimating the health literacy of (expectant) parents based on the Conversational Health Literacy Assessment Tool for general care, which in turn was based on the Health Literacy Questionnaire. We used a thorough iterative process including different maternity care providers, (expectant) parents, and a panel of experts. This expert panel comprised representatives from knowledge institutions, professional associations, and care providers with whom midwives and maternity care assistants work closely. Testing, evaluation and adjustment took place in consecutive rounds and was conducted in the Netherlands between 2019 and 2022. RESULTS: The conversational tool 'CHAT-maternity-care' covers four key domains: (1) supportive relationship with care providers; (2) supportive relationship within parents' personal network; (3) health information access and comprehension; (4) current health behaviour and health promotion. Each domain contains multiple example questions and example observations. Participants contributed to make the example questions and example observations accessible and usable for daily practice. The CHAT-maternity-care supports maternity care providers in estimating (expectant) parents' health literacy during routine conversations with them, increased maternity care providers' awareness of health literacy and helped them to identify where attention is necessary regarding (expectant) parents' health literacy. CONCLUSIONS: The CHAT-maternity-care is a promising conversational tool to estimate (expectant) parents' health literacy. It covers the relevant constructs of health literacy from both the Conversational Health Literacy Assessment Tool and Health Literacy Questionnaire, applied to maternity care. A preliminary evaluation of the use revealed positive feedback. Further testing and evaluation of the CHAT-maternity-care is required with a larger and more diverse population, including more (expectant) parents, to determine the effectiveness, perceived barriers, and perceived facilitators for implementation.

Women's Birth Beliefs During Pregnancy and Postpartum in the Netherlands: A Quantitative Cross-Sectional Study.

INTRODUCTION: Women and care providers increasingly regard childbirth as a medical process, resulting in high use of medical interventions, which could negatively affect a woman's childbirth experience. Women's birth beliefs may be key to understanding the decisions they make and the acceptance of medical interventions in childbirth. In this study we explore women's beliefs about birth as a natural and medical process and the factors that are associated with women's birth beliefs. METHODS: Data were obtained from a cross-sectional survey of women living in the Netherlands asking them about their experiences during pregnancy and childbirth, including their beliefs about birth as a natural and medical process. RESULTS: A total of 3494 women were included in this study. Mean scores of natural birth beliefs ranged between 3.73 and 4.01 points, and medical birth belief scores ranged between 2.92 and 3.12 points. There were significant but very small changes between prenatal and postnatal birth beliefs. Regression analyses showed that (previous) childbirth experiences were the most consistent predictor of women's birth beliefs. DISCUSSION: Women's high scores on natural birth beliefs and lower scores on medical birth beliefs correspond with the philosophy of Dutch perinatal care that considers pregnancy and childbirth to be natural processes. Perinatal care providers must be aware of women's birth beliefs and recognize that they as professionals influence women's birth beliefs. They make an important contribution to women's perinatal experiences, which affects both women's natural and medical birth beliefs.

Women's decision-making autonomy in Dutch maternity care.

BACKGROUND: A positive childbirth experience is an important outcome of maternity care. A significant component of a positive birth experience is the ability to exercise autonomy in decision-making. In this study, we explore women's reports of their autonomy during conversations about their care with maternity care practitioners during pregnancy and childbirth. METHOD: Data were obtained from a cross-sectional survey of women living in The Netherlands that asked about their experiences during pregnancy and childbirth, including their role in conversations concerning decisions about their care. RESULTS: A total of 3494 women were included in this study. Most women scored high on autonomy in decision-making conversations. During the latter stage of pregnancy (32+ weeks) and in childbirth, women reported significantly lower levels of autonomy in their care conversations with obstetricians as compared with midwives. Linear regression analyses showed that women's perception of personal treatment increased women's reported autonomy in their conversations with both midwives and obstetricians. Almost half (49.1%) of the women who had at least one intervention during birth reported pressure to accept or submit to that intervention. This was indicated by 48.3% of women with induced labor, 47.3% who had an instrumental vaginal birth, 45.2% whose labor was augmented, and 41.9% of women who had a cesarean birth. CONCLUSIONS: In general, women's sense of autonomy in decision-making conversations during prenatal care and birth is high, but there is room for improvement, and this appeared most notably in conversations with obstetricians. Women's sense of autonomy can be enhanced with personal treatment, including shared decision-making and the avoidance of pressuring women to accept interventions.

Sources of information used by women during pregnancy and the perceived quality.

BACKGROUND: Access to reliable information is critical to women's experience and wellbeing during pregnancy and childbirth. In our information-rich society, women are exposed to a wide range of information sources. The primary objective of this study was to explore women's use of information sources during pregnancy and to examine the perceived usefulness and trustworthiness of these sources. METHOD: A quantitative cross-sectional study of Dutch women's experiences with various information sources during pregnancy, including professional (e.g. healthcare system), and informal sources, divided into conventional (e.g. family or peers) and digital sources (e.g. websites or apps). Exploratory backward stepwise multiple regression was performed to identify associations between the perceived quality of information sources and personal characteristics. RESULTS: A total of 1922 pregnant women were included in this study. The most commonly used information sources were midwives (91.5%), family or friends (79.3%), websites (77.9%), and apps (61%). More than 80% of women found professional information sources trustworthy and useful, while digital sources were perceived as less trustworthy and useful. Personal factors explain only a small part of the variation in the perceived quality of information sources. CONCLUSION: Even though digital sources are perceived as less trustworthy and useful than professional and conventional sources, they are among the most commonly used sources of information for pregnant women. To meet the information needs of the contemporary generation of pregnant women it is essential that professionals help in the development of digital information sources.

Impact of maternal height on birthweight classification in singleton births at term: a cohort study in The Netherlands.

OBJECTIVE: To assess the association between maternal height and birthweight in a healthy population and to study the effect of maternal height on the classification of birthweight as small for gestational age (SGA) and large for gestational age (LGA). METHODS: A descriptive, observational retrospective study was conducted in a low risk population in the Netherlands. The study included term singleton healthy nonsmoking pregnant women with normal body mass index (n = 9291). We calculated the impact of maternal height on birthweight using multiple linear regression analyses with adjustment for gestational age, gender, and parity. We calculated the number of newborns classified as SGA and LGA using the cutoff point of the Dutch Birthweight chart, which does not customize for maternal height. Subsequently, we calculated the changes in classification from SGA and LGA to appropriate for gestational age (AGA) in case of customization for maternal height. RESULTS: A significant association was found between maternal height and birthweight; 15.0 g higher birthweight per extra cm maternal height (95% confidence interval 13.8-16.1; p<.001; R2 model = 0.28). The incidence of SGA was 7.1% (range 17.4-2.0% form shortest to tallest maternal height category) and of LGA 8.4% (range 1.9-21.5% from shortest to tallest maternal height category). We calculated a shift in classification: 114 newborns (17.3%) in shorter (<167 cm) women previously SGA and 165 newborns (21.1%) in taller (>173 cm) women previously LGA were classified as AGA when controlling for maternal height. CONCLUSIONS: Maternal height is significantly associated with birthweight. Birthweight charts customized for maternal height change classification in one out of six SGA or LGA newborns at term.

Evaluating the effect of an educational intervention on student midwife self-efficacy for their role as physiological childbirth advocates.

INTRODUCTION: Midwifery education that strengthens self-efficacy can support student midwives in their role as advocates for a physiological approach to childbirth. METHODS: To assess the effect of an educational intervention on self-efficacy, a pre- and post-intervention survey was administered to a control group and an intervention group of third year student midwives. The General Self-Efficacy Scale (GSES) was supplemented with midwifery-related self-efficacy questions related to behaviour in home and hospital settings, the communication of evidence, and ability to challenge practice. RESULTS: Student midwives exposed to midwifery education designed to strengthen self-efficacy demonstrated significantly higher levels of general self-efficacy (p = .001) when contrasted to a control cohort. These students also showed significantly higher levels of self-efficacy in advocating for physiological childbirth (p = .029). There was a non-significant increase in self-efficacy in the hospital setting in the intervention group, a finding that suggests that education may ameliorate the effect of hospital settings on midwifery practice. DISCUSSION: In spite of the small size of the study population, education that focuses on strengthening student midwife self-efficacy shows promise.

Effect of the use of a national information brochure about fetal movements on patient delay.

BACKGROUND: Perinatal audits in the Netherlands showed that stillbirth was nearly always preceded by a period of reduced fetal movements. Patient or caregiver delay was identified as a substandard care factor. AIM: To determine whether the use of a new information brochure for pregnant women on fetal movements results in less patient delay in contacting their maternity caregiver. METHODS: A pre- and post-survey cohort study in the Netherlands, including 140 women in maternity care with a singleton pregnancy, expecting their first child. All participating women filled out a baseline questionnaire, Cambridge Worry Scale and pre-test questionnaire at the gestational age of 22-24 weeks. Subsequently, the intervention group received a newly developed information brochure on fetal movements. At a gestational age of 28 weeks, all women received the post-test questionnaire. Multiple regression analyses were used. FINDINGS: Per-protocol analysis showed less patient delay in the intervention group compared to the control group (Odds Ratio 0.43; 95% Confidence Interval 0.17-0.86, p=0.02). A significant linear relation was observed between reading the information brochure and an increase of knowledge about fetal movements (B=1.2, 95% Confidence Interval 1.0-1.4, p<0.001). Maternal concerns did not affect patient delay to report reduced fetal movements. CONCLUSION: Use of an information brochure regarding fetal movements has the potential to reduce patient delay and increase knowledge about reduced fetal movements. A national survey to determine the effect of an information brochure about reduced fetal movements on patient delay and stillbirth rates is needed.

Creating an Optimality Index - Netherlands: a validation study.

BACKGROUND: At present, the maternity care system in the Netherlands is being reorganized into an integrated model of care, shifting the focus of midwives to include increasing numbers of births in hospital settings and clients with medium risk profiles. In light of these changes, it is useful for midwives to have a tool which may help them in reflecting upon care practices that promote physiological childbirth practices. The Optimality Index-US is an evidence based tool, designed to measure optimal perinatal care processes and outcomes. It has been validated for use in the United States (OI-US), United Kingdom (OI-UK) and Turkey (OI-TR). The objective of this study was to adapt the OI-US for the Dutch maternity care setting (OI-NL). METHODS: Translation and back translation were applied to create the OI-NL. A panel of maternity care experts (n = 10) provided input for face validation items in the OI-NL. Assessment of inter-rater reliability and ease of use was also conducted. Following this, the OI-NL was used prospectively to collect data on 266 women who commenced intrapartum care under the responsibility of a midwife. Twice groups were compared, based on parity and on care-setting at birth. Mean scores between these groups, corrected for perinatal background factors were assessed for discriminant validity. RESULTS: Face validity was established for OI-NL on the basis of expert input. Discriminant validity was confirmed by conducting multiple regressions analyses for parity (ß = 6.21, P = 0.00) and for care-setting (ß = 12.1, p = 0.00). Inter-rater reliability was 98%, with one item (Apgar score) sensitive to scoring differences. CONCLUSION: OI-NL is a valid and reliable tool for use in the Dutch maternity care setting. In addition to its value for assessing evidence-based maternity care processes and outcomes, there is potential for use for learning and reflection. Against the backdrop of a changing maternity care system, and due to the specificity of its items OI-NL may be of value as a tool for detecting subtle changes indicative of escalating medicalization of childbirth in the Netherlands.

Factors affecting perceived change in physical activity in pregnancy.

OBJECTIVE: reduction of physical activity (PA) during pregnancy is common but undesirable, as it is associated with negative outcomes, including excessive gestational weight gain. Our objective was to explore changes in five types of activity that occurred during pregnancy and the behavioural determinants of the reported changes in PA. DESIGN: we performed a secondary analysis of a cross sectional survey that was constructed using the ASE-Model - an approach to identifying the factors that drive behaviour change that focuses on Attitude, Social influence, and self-Efficacy. PARTICIPANTS: 455 healthy pregnant women of all gestational ages, receiving prenatal care from midwifery practices in the Netherlands. FINDINGS: more than half of our respondents reported a reduction in their PA during pregnancy. The largest reduction occurred in sports and brief rigorous activities, but other types of PA were reduced as well. Reduction of PA was more likely in women who considered themselves as active before pregnancy, women who experienced pregnancy-related barriers, women who were advised to reduce their PA, and multiparous women. Fewer than 5% increased their PA. Motivation to engage in PA was positively associated with enjoying PA. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: all pregnant women should be informed about the positive effects of staying active and should be encouraged to engage in, or to continue, moderately intensive activities like walking, biking or swimming. Our findings concerning the predictors of PA reduction can be used to develop an evidence-based intervention aimed at encouraging healthy PA during pregnancy.

The use of midwife-led primary antenatal care by obese women in The Netherlands: An explorative cohort study.

OBJECTIVE: to study the effect of body mass index (BMI) on the use of antenatal care by women in midwife-led care. DESIGN: an explorative cohort study. SETTING: 11 Dutch midwife-led practices. PARTICIPANTS: a cohort of 4421 women, registered in the Midwifery Case Registration System (VeCaS), who received antenatal care in midwife-led practices in the Netherlands and gave birth between October 2012 and October 2014. FINDINGS: the mean start of initiation of care was at 9.3 (SD 4.6) weeks of pregnancy. Multiple linear regression showed that with an increasing BMI initiation of care was significantly earlier but BMI only predicted 0.2% (R2) of the variance in initiation of care. The mean number of face-to- face antenatal visits in midwife-led care was 11.8 (SD 3.8) and linear regression showed that with increasing BMI the number of antenatal visits increased. BMI predicted 0.1% of the variance in number of antenatal visits. The mean number of antenatal contacts by phone was 2.2 (SD 2.6). Multiple linear regression showed an increased number of contacts by phone for BMI categories 'underweight' and 'obese class I'. BMI categories predicted 1% of the variance in number of contacts by phone. KEY CONCLUSIONS: BMI was not a relevant predictor of variance in initiation of care and number of antenatal visits. Obese pregnant women in midwife-led practices do not delay or avoid antenatal care. IMPLICATIONS FOR PRACTICE: Taking care of pregnant women with a high BMI does not significantly add to the workload of primary care midwives. Further research is needed to more fully understand the primary maternal health services given to obese women.

The effect of gestational weight gain on likelihood of referral to obstetric care for women eligible for primary, midwife-led care after antenatal booking.

OBJECTIVE: to examine the effect of gestational weight gain (GWG) on likelihood of referral from midwife-led to obstetrician-led care during pregnancy and childbirth for women in primary care at the outset of their pregnancy. DESIGN: secondary analysis of data from a prospective cohort study. SETTING: Dutch midwife-led practices. PARTICIPANTS: a cohort of 1288 women of Northern European descent, with uncomplicated, singleton pregnancy at antenatal booking who consequently were eligible for primary, midwife-led care. MEASUREMENTS: because of the absence of an established GWG guideline in the Netherlands, we compared the effect of inadequate and excessive GWG according to two GWG guidelines: the criterion traditionally used, which is based on knowledge of the physiological components of GWG, advising 10-15kg as a normal GWG irrespective of a woman׳s BMI category, and the 2009 Institute of Medicine recommendations (IOMr) on GWG, which provide BMI related advice. Outcome measures were: number of women referred from midwife-led to obstetrician-led care during pregnancy and during childbirth; indications of referral and birth outcomes. FINDINGS: GWG above traditional criteria (Tc; >15kg between 12 and 36 weeks) was associated with increased odds for referral during childbirth (adjusted odds ratio (aOR) 1.88; 95% confidence interval (CI) 1.22-2.90), but had no effect on referral during pregnancy (aOR .86; 95% CI .57-1.30). No associations were established between GWG below Tc (<10kg) and referral during pregnancy (aOR 1.08; 95% CI .78-1.50) or childbirth (aOR 1.08; 95% CI .74-1.56). No associations were found between GWG below and above the IOMr and referral during pregnancy (below IOMr: aOR 1.01; 95% CI .71-1.45; above IOMr: aOR .89; 95% CI .61-1.28) or childbirth (below IOMr: aOR .85; 95% CI .57-1.25; above IOMr: aOR 1.09; 95% CI .73-1.63). With regard to the effect of GWG according to both recommendations on indications for referral and birth outcomes, GWG above Tc was associated with higher rates of referral for hypertensive disorders (aOR 1.91; 95% CI 1.04-3.50) and for meconium stained liquor (aOR 2.22; CI 1.33-3.71) after adjusting for BMI and parity. CONCLUSIONS: GWG above Tc - irrespective of BMI category - was associated with doubled odds of referral to specialist care during childbirth. GWG below or above IOMR and GWG below TC were not associated with adverse obstetric outcomes in women who were eligible for primary care at the outset of their pregnancy. IMPLICATIONS FOR PRACTICE: weight gain <15kg between 12 and 36 weeks is advised for women in all BMI categories in this population. It is important to validate GWG guidelines in a target population before implementing them.

A simple formula for the calculation of sample size in pilot studies.

One of the goals of a pilot study is to identify unforeseen problems, such as ambiguous inclusion or exclusion criteria or misinterpretations of questionnaire items. Although sample size calculation methods for pilot studies have been proposed, none of them are directed at the goal of problem detection. In this article, we present a simple formula to calculate the sample size needed to be able to identify, with a chosen level of confidence, problems that may arise with a given probability. If a problem exists with 5% probability in a potential study participant, the problem will almost certainly be identified (with 95% confidence) in a pilot study including 59 participants.

Weight gain in healthy pregnant women in relation to pre-pregnancy BMI, diet and physical activity.

OBJECTIVE: to explore gestational weight gain in healthy women in relation to pre-pregnancy Body Mass Index, diet and physical activity. DESIGN: a cross-sectional survey was conducted among 455 healthy pregnant women of all gestational ages receiving antenatal care from an independent midwife in the Netherlands. Weight gain was assessed using the Institute of Medicine (IOM) guidelines and classified as below, within, or above the guidelines. A multinomial regression analysis was performed with weight gain classifications as the dependent variable (within IOM-guidelines as reference). Independent variables were pre-pregnancy Body Mass Index, diet (broken down into consumption of vegetables, fruit and fish) and physical activity (motivation to engage in physical activity, pre-pregnancy physical activity and decline in physical activity during pregnancy). Covariates were age, gestational age, parity, ethnicity, family income, education, perceived sleep deprivation, satisfaction with pre-pregnancy weight, estimated prepregnancy body mass index, smoking, having a weight gain goal and having received weight gain advice from the midwife. FINDINGS: forty-two per cent of the women surveyed gained weight within the guidelines. Fourteen per cent of the women gained weight below the guidelines and 44 per cent gained weight above the guidelines. Weight gain within the guidelines, compared to both above and below the guidelines, was not associated with pre-pregnancy Body Mass Index nor with diet. A decline in physical activity was associated with weight gain above the guidelines (OR 0.54, 95 per cent CI 0.33-0.89). Weight gain below the guidelines was seen more often in women who perceived a greater sleep deprivation (OR 1.20, 95 per cent CI 1.02-1.41). Weight gain above the guidelines was seen less often in Caucasian women in comparison to non-Caucasian women (OR 0.22, 95 per cent CI 0.08-0.56) and with women who did not stop smoking during pregnancy (OR 0.49, 95 per cent CI 0.25-0.95). KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: a decline in physical activity was the only modifiable factor in our population associated with weight gain above the gain recommended by the guidelines. Prevention of reduced physical activity during pregnancy seems a promising approach to promoting healthy weight gain. Interventions to promote healthy weight gain should focus on all women, regardless of pre-pregnancy body mass index.

Factors influencing maternal distress among Dutch women with a healthy pregnancy.

BACKGROUND: Maternal distress is a public health concern. Assessment of emotional wellbeing is not integrated in Dutch antenatal care. Midwives need to understand the influencing factors in order to identify women who are more vulnerable to experience maternal distress. OBJECTIVE: To examine levels of maternal distress during pregnancy and to determine the relationship between maternal distress and aetiological factors. METHODS: A cross-sectional study including 458 Dutch-speaking women with uncomplicated pregnancies during all trimesters of pregnancy. Data were collected with questionnaires between 10 September and 6 November 2012. Demographic characteristics and personal details were obtained. Maternal distress was measured with the Edinburgh Depression Scale (EDS), State-Trait Anxiety Inventory (STAI), and Pregnancy-Related Anxiety Questionnaire (PRAQ). Behaviour was measured with Coping Operations Preference Enquiry-Easy (COPE-Easy). Descriptive statistics and multiple linear regression analysis were used. RESULTS: Just over 20 percent of the women in our sample (21.8%) had a heightened score on one or more of the EDS, STAI or PRAQ. History of psychological problems (B=1.071; p=.001), having young children (B=2.998; p=.001), daily stressors (B=1.304; p=<.001), avoidant coping (B=1.047, p=<.001), somatisation (B=.484; p=.004), and negative feelings towards the forthcoming birth (B=.636; p=<.001) showed a significant positive relationship with maternal distress. Self-disclosure (B=-.863; p=.004) and acceptance of the situation (B=-.542; p=.008) showed a significant negative relationship with maternal distress. CONCLUSION: Maternal distress occurs among women with a healthy pregnancy and is significantly influenced by a variety of factors. Midwives need to recognise the factors that make women more vulnerable to develop and experience maternal distress in order to give adequate advice about how to best cope with this condition.

Dutch midwives' behavioural intentions of antenatal management of maternal distress and factors influencing these intentions: an exploratory survey.

OBJECTIVE: to explore midwives' behavioural intentions and the determinants of these intentions with regard to the management of antenatal care of women with maternal distress. DESIGN: an exploratory survey using a questionnaire. Descriptive statistics calculated expanded TPB constructs, demographic information, personal characteristics and work related details. Multiple linear regression analyses were used to examine which factors influence midwives' intention to provide antenatal care of maternal distress. SETTING: midwives working in Dutch primary care. PARTICIPANTS: 112 midwives completed the survey. RESULTS: midwives did not report a clear intention to screen for maternal distress (3.46 ± 1.8). On average, midwives expressed a positive intention to support women with maternal distress (4.63 ± 1.57) and to collaborate with other health-care professionals (4.63 ± 1.57). Finding maternal distress an interesting topic was a positive predictor for the intention to screen (B=0.383; p=0.005), to support (B=0.637; p=<0.000) and to collaborate (B=0.455; p=0.002). Other positive predictors for the intention to screen for maternal distress were years of work experience (B=0.035; p=0.028), attitude about the value of screening (B=0.326; p=0.002), and self-efficacy (B=0.248; p=0.004). A positive attitude toward support for women with maternal distress (B=0.523; p=0.017) predicted the intention to support these women. Number of years of work experience (B=0.042; p=0.017) was a positive predictor for the intention to collaborate with other health-care professionals. KEY CONCLUSIONS: the intention to screen for maternal distress was less evident than the intention to support women with maternal distress and the intention to collaborate with other health-care professionals. Important factors predicting the midwife's intention to screen, support and collaborate were finding maternal distress an interesting topic, years of work experience, attitude about the value of screening and support and self-efficacy about screening. IMPLICATIONS FOR PRACTICE: to provide care involving all three components of antenatal management of maternal distress implies efforts to influence the factors that predict the intention to screen, to support women with maternal distress and the intention to collaborate with other health-care professionals.

Influence on birthing positions affects women's sense of control in second stage of labour.

OBJECTIVE: to explore whether choices in birthing positions contributes to women's sense of control during birth. DESIGN: survey using a self-report questionnaire. Multiple regression analyses were used to investigate which factors associated with choices in birthing positions affected women's sense of control. SETTING: midwifery practices in the Netherlands. PARTICIPANTS: 1030 women with a physiological pregnancy and birth from 54 midwifery practices. FINDINGS: in the total group of women (n=1030) significant predictors for sense of control were: influence on birthing positions (self or self together with others), attendance of antenatal classes, feelings towards birth in pregnancy and pain in second stage of labour. For women who preferred other than supine birthing positions (n=204) significant predictors were: influence on birthing positions (self or self together with others), feelings towards birth in pregnancy, pain in second stage of labour and having a home birth. For these women, influence on birthing positions in combination with others had a greater effect on their sense of control than having an influence on their birthing positions just by themselves. KEY CONCLUSIONS: women felt more in control during birth if they experienced an influence on birthing positions. For women preferring other than supine positions, home birth and shared decision-making had added value. IMPLICATIONS FOR PRACTICE: midwives can play an important role in supporting women in their use of different birthing positions and help them find the positions they feel most comfortable in. Thus, contributing to women's positive experience of birth.

Patterns of gestational weight gain in healthy, low-risk pregnant women without co-morbidities.

BACKGROUND: little is known of the impact of gestational weight gain (GWG) in relation to Body Mass Index (BMI) classification on perinatal outcomes in healthy pregnant women without co-morbidities. As a first step, the prevalence of obesity and the distribution of GWG in relation to the Institute of Medicine (IOM) 2009 guidelines for GWG were examined. METHODS: data from a prospective cohort study of - a priori - low risk, pregnant women from five midwife-led practices (n=1449) were analysed. Weight was measured at 12, 24 and 36 weeks. FINDINGS: at 12 weeks, 1.4% of the women were underweight, 53.8% had a normal weight, 29.6% were overweight, and 15.1% were obese according to the WHO classification of BMI. In our study population, 60% of the women did not meet the IOM recommendations: 33.4% had insufficient GWG and 26.7% gained too much weight. Although BMI was negatively correlated to total GWG (p<.001), overweight and obese women class I had a significant higher risk of exceeding the IOM guidelines. Normal weight women had a significantly higher risk of gaining less weight than recommended. Obese women classes II and III were at risk in both over- and undergaining. CONCLUSIONS: our data showed that the majority of women were unable to stay within recommended GWG ranges without additional interventions. The effects on pregnancy and health outcomes of falling out the IOM guidelines remain unclear for - a priori - low risk women. Since interventions to control GWG would have considerable impact on women and caregivers, harms and benefits should be well-considered before implementation.

Preferred place of birth: characteristics and motives of low-risk nulliparous women in the Netherlands.

OBJECTIVE: to explores preferences, characteristics and motives regarding place of birth of low-risk nulliparous women in the Netherlands. DESIGN: a prospective cohort study of low-risk nulliparous women and their partners starting their pregnancy in midwifery-led care or in obstetric-led care. Data were collected using a self-administered questionnaire, including questions on demographic, psychosocial and pregnancy factors and statements about motives with regard to place of birth. Depression, worry and self-esteem were explored using the Edinburgh Depression Scale (EDS), the Cambridge Worry Scale (CWS) and the Rosenberg Self Esteem Scale (RSE). SETTING: participants were recruited in 100 independent midwifery practices and 14 hospitals from 2007 to 2011. PARTICIPANTS: 550 low-risk nulliparous women; 231 women preferred a home birth, 170 women a hospital birth in midwifery-led care and 149 women a birth in obstetric-led care. FINDINGS: Significant differences in characteristics were found in the group who preferred a birth in obstetric-led care compared to the two groups who preferred midwifery-led care. Those women were older (F (2,551)=16.14, p<0.001), had a higher family income (χ(2) (6)=18.87, p=0.004), were more frequently pregnant after assisted reproduction (χ(2)(2)=35.90, p<0.001) and had a higher rate of previous miscarriage (χ(2)(2)=25.96, p<0.001). They also differed significantly on a few emotional aspects: more women in obstetric-led care had symptoms of a major depressive disorder (χ(2)(2)=6.54, p=0.038) and were worried about health issues (F (2,410)=8.90, p<0.001). Women's choice for a home birth is driven by a desire for greater personal autonomy, whereas women's choice for a hospital birth is driven by a desire to feel safe and control risks. KEY CONCLUSIONS: the characteristics of women who prefer a hospital birth are different than the characteristics of women who prefer a home birth. It appears that for women preferring a hospital birth, the assumed safety of the hospital is more important than type of care provider. This brings up the question whether women are fully aware of the possibilities of maternity care services. Women might need concrete information about the availability and the characteristics of the services within the maternity care system and the risks and benefits associated with either setting, in order to make an informed choice where to give birth.

The effect of guiding questions on students' performance and attitude towards statistics.

BACKGROUND: In this study, the effect of guidance on students' performance was investigated. This effect was hypothesized to be manifested through a reduction of cognitive load and enhancement of self-explanations. AIM: The goal of this study was to investigate the effect of guiding questions on students' understanding of statistics. SAMPLE AND METHOD: In an experimental setting, two randomly selected groups of students (N= 49) answered achievement and transfer questions on statistics as a measure of performance. Students in the intervention condition were given guiding questions to direct their way of reasoning before they answered the achievement questions. The students in the control condition were asked to write down their way of thinking before they answered the same achievement questions. In this way, both groups were stimulated to self-explain, but only the reasoning processes of the students in the intervention condition were guided. RESULTS AND CONCLUSION: It was found that students in the intervention condition performed significantly better on achievement and transfer questions and that this effect of guidance was mediated by self-explanations. Attitude towards statistics was positively related to performance.

The effect of directive tutor guidance on students' conceptual understanding of statistics in problem-based learning.

BACKGROUND: Education is aimed at students reaching conceptual understanding of the subject matter, because this leads to better performance and application of knowledge. Conceptual understanding depends on coherent and error-free knowledge structures. The construction of such knowledge structures can only be accomplished through active learning and when new knowledge can be integrated into prior knowledge. AIMS: The intervention in this study was directed at both the activation of students as well as the integration of knowledge. SAMPLE: Undergraduate university students from an introductory statistics course, in an authentic problem-based learning (PBL) environment, were randomly assigned to conditions and measurement time points. METHOD: In the PBL tutorial meetings, half of the tutors guided the discussions of the students in a traditional way. The other half guided the discussions more actively by asking directive and activating questions. To gauge conceptual understanding, the students answered open-ended questions asking them to explain and relate important statistical concepts. RESULTS AND CONCLUSIONS: Results of the quantitative analysis show that providing directive tutor guidance improved understanding. Qualitative data of students' misconceptions seem to support this finding. Long-term retention of the subject matter seemed to be inadequate.
