How, when, and who should ask about pregnancy intentions in primary care? A qualitative study of women's preferences

BACKGROUND

For health services to help people plan for or prevent pregnancy, health professionals need an acceptable way to identify individuals' preferences.

OBJECTIVE

To assess women's views on the acceptability of specific questions about pregnancy preferences when asked by health professionals in a variety of primary care contexts.

METHODS

One-to-one in-depth interviews with 13 women aged 18-48 from across the UK, involving role-play scenarios and ranking exercises. Interviews covered a range of settings and health professionals, different question wording, and ways of asking (in person or digitally). We conducted a thematic Framework Analysis, focussing on themes relating to feelings and preferences.

RESULTS

Women were generally open to being asked about pregnancy preferences if they understood the rationale, it was asked in a relevant context, such as in women's health-related consultations, and there was follow-up. After signposting, an open question, such as 'How would you feel about having a baby in the next year?' was preferred in a face-to-face context as it enabled discussion. While some women valued a face-to-face discussion with a health professional, for others the privacy and convenience of a digital option was preferred; methods should be tailored to the target population.

CONCLUSION

Discussion of pregnancy preferences via a range of formats is acceptable to, and valued by, women in the UK across a range of primary care settings. Acceptability to health professionals and feasibility of implementation needs further exploration and would benefit from greater public awareness of the benefits of pregnancy planning.

Changes in contraceptive use during the second COVID-19 lockdown in Brazil: A web-based survey

OBJECTIVE

We assessed contraceptive use changes during the second lockdown due to COVID-19 in Brazil and their associated factors.

STUDY DESIGN

This was a longitudinal web-based study in which 725 non-pregnant Brazilian women aged 18 to 49 completed an online structured survey about their contraceptive practices in two rounds in 2021. Multivariate multinomial logistic regression was used to analyze factors associated with contraceptive use changes during COVID-19.

RESULTS

Sixty percent reported they changed their contraceptive use during COVID-19, especially starting to use a method or switching to a more effective one (32%). In adjusted analysis, women who were ambivalent about a future pregnancy were more likely to switch to a more effective method (adjusted odds ratio [aOR] 2.33, 95% CI 1.42-3.83) and to stop using contraceptive (aOR 3.64, 95% CI 1.91-6.91). Women with a partner were less likely to switch to a more effective method (aOR 0.61, 95% CI 0.39-0.93) and to stop using contraceptive (aOR 0.53, 95% CI 0.31-0.93), but more likely to switch to a less effective method (aOR 2.25, 95% CI 1.16-4.34). Age was also associated with contraceptive use changes.

CONCLUSIONS

Contraceptive use among Brazilian women during COVID-19 depended on their age and partnership status. During the period of the highest peak in the number of cases and deaths in the country, ambivalence towards a future pregnancy increased changes in contraceptive use.

IMPLICATIONS

Contraceptive changes were observed during a two-wave web-survey in Brazil depending on women's age and partnership status. Ambivalence towards a future pregnancy increased changes in contraceptive use and should be considered in future studies regarding sexual and reproductive health and COVID-19 as well as in family planning program implementation.

Maternal folic acid supplementation and the risk of ankyloglossia (tongue-tie) in infants; a systematic review

BACKGROUND

Maternal folic acid supplementation is protective against the development of neural tube defects (NTDs) in babies. However, recent public-facing communications have raised concerns about a causal relationship between folic acid supplementation, particularly after the first trimester, and ankyloglossia (tongue-tie) in infants. Non-evidence-based communications are potentially harmful because they could adversely affect adherence to folic acid supplementation, increasing NTD occurrence. This study aimed to review evidence on the relationships between maternal folic acid supplementation during preconception and/or pregnancy and the risk of ankyloglossia in infants.

METHODS

We searched the databases MEDLINE, EMBASE, Cochrane CENTRAL, and Scopus. We searched for observational, and interventional studies, and systematic reviews investigating the effect of maternal folic acid supplementation during preconception or pregnancy on the occurrence of ankyloglossia in offspring. The search was registered on PROSPERO on 01/12/2022, ID: CRD42022375862.

RESULTS

The database searches yielded 93 articles. After removing duplicates and screening titles and abstracts, 26 remained. One article was judged relevant for inclusion in analyses; a case-control study that directly mentions the relationship between folic acid supplementation and ankyloglossia. This study reported that regular intake of folic acid supplements was higher in women with infants with ankyloglossia. However, this study has limitations regarding design, selection bias, and confounding, calling the findings into question.

CONCLUSIONS

Insufficient evidence exists for a relationship between folic acid supplementation and ankyloglossia. Currently, the benefits of folic acid supplementation far outweigh the risks. This must be clearly communicated to patients by their clinicians during preconception and antenatal care.

Predictive ability of the Desire to Avoid Pregnancy scale

BACKGROUND

A longstanding gap in the reproductive health field has been the availability of a screening instrument that can reliably predict a person's likelihood of becoming pregnant. The Desire to Avoid Pregnancy Scale is a new measure; understanding its sensitivity and specificity as a screening tool for pregnancy as well as its predictive ability and how this varies by socio-demographic factors is important to inform its implementation.

METHODS

This analysis was conducted on a cohort of 994 non-pregnant participants recruited in October 2018 and followed up for one year. The cohort was recruited using social media as well as advertisements in a university, school, abortion clinic and outreach sexual health service. Almost 90% of eligible participants completed follow-up at 12 months; those lost to follow-up were not significantly different on key socio-demographic factors. We used baseline DAP score and a binary variable of whether participants experienced pregnancy during the study to assess the sensitivity, specificity, area under the ROC curve (AUROC) and positive and negative predictive values (PPV and NPV) of the DAP at a range of cut-points. We also examined how the predictive ability of the DAP varied according to socio-demographic factors and by the time frame considered (e.g., pregnancy within 3, 6, 9 and 12 months).

RESULTS

At a cut-point of 2 on the 0-4 range of the DAP scale, the DAP had a sensitivity of 0.78, a specificity of 0.81 and an excellent AUROC of 0.87. In this sample the cumulative incidence of pregnancy was 16% (95%CI 13%, 18%) making the PPV 43% and the NPV 95% at this cut-point. The DAP score was the factor most strongly associated with pregnancy, even after age and number of children were taken into account. The association between baseline DAP score and pregnancy did not differ across time frames.

CONCLUSIONS

This is the first study to assess the DAP scale as a screening tool and shows that its predictive ability is superior to the limited pre-existing pregnancy prediction tools. Based on our findings, the DAP could be used with a cut-point selected according to the purpose.

Desire to Avoid Pregnancy scale: clinical considerations and comparison with other questions about pregnancy preferences

BACKGROUND

Clinicians and women of reproductive age would benefit from a reliable way to identify who is likely to become pregnant in the next year, in order to direct health advice. The 14-item Desire to Avoid Pregnancy (DAP) scale is predictive of pregnancy; this paper compares it with other ways of assessing pregnancy preferences to shortlist options for clinical implementation.

METHODS

A cohort of 994 UK women of reproductive age completed the DAP and other questions about pregnancy preferences, including the Attitude towards Potential Pregnancy Scale (APPS), at baseline and reported on pregnancies quarterly for a year. For each question, DAP item and combinations of DAP items, we examined the predictive ability, sensitivity, specificity, area under the receiver operating curve (AUROC), and positive and negative predictive values.

RESULTS

The AUROCs and predictive ability of the APPS and DAP single items were weaker than the full DAP, though all except one had acceptable AUROCs (>0.7). The most predictive individual DAP item was 'It would be a good thing for me if I became pregnant in the next 3 months', where women who strongly agreed had a 66.7% chance of pregnancy within 12 months and the AUROC was acceptable (0.77).

CONCLUSION

We recommend exploring the acceptability to women and healthcare professionals of asking a single DAP item ('It would be a good thing for me if I became pregnant in the next 3 months'), possibly in combination with additional DAP items. This will help to guide service provision to support reproductive preferences.

Evaluation of the psychometric properties of the Reproductive Autonomy Scale for use in the UK

BACKGROUND

Reproductive autonomy-control over outcomes including contraceptive use and childbearing-is a human right and vital to women's empowerment. Those whose reproductive autonomy is threatened by the structures and relationships in their lives are at risk of coercion and unplanned pregnancy and could benefit from additional services. The Reproductive Autonomy Scale (RAS) was developed in the USA to assess women's reproductive autonomy; this study evaluates the RAS for use in the UK.

METHODS

After testing, the RAS was incorporated into an online survey of women of reproductive age. Those who were sexually active were asked to complete the RAS, which was evaluated according to classical test theory. Reliability was assessed via internal consistency and a 3-month test-retest. Construct validity was assessed using hypothesis testing and confirmatory factor analysis.

RESULTS

For 826 women the RAS was highly acceptable, with a response rate of >97.7%. Almost the whole range of reproductive autonomy scores were captured. Internal consistency was good, with a Cronbach's α of 0.75. Test-retest reliability was fair-good with an intraclass correlation coefficient of 0.67. Construct validity analysis found the scale to be valid based on our hypothesis that among women who want to avoid pregnancy, those with higher reproductive autonomy will be more likely to use contraception. The three-factor structure of the scale was confirmed on confirmatory factor analysis.

CONCLUSION

The RAS is valid and reliable for use in the UK. This tool holds potential utility across research, clinical practice, health interventions and policy development.

How common is natural conception in women who have had a livebirth via assisted reproductive technology? Systematic review and meta-analysis

STUDY QUESTION

What is the proportion of women who experience natural conception after a livebirth via assisted reproductive technology (ART)?

SUMMARY ANSWER

Current evidence suggests that natural conception pregnancy may occur in at least one in five women after having a baby via IVF or ICSI.

WHAT IS KNOWN ALREADY

It is widely known that some women having babies via ART go on to conceive naturally. This reproductive history is of media interest and often described as 'miracle' pregnancies.

STUDY DESIGN, SIZE, DURATION

A systematic review with meta-analysis was carried out. Ovid Medline, Embase, and PsycINFO were searched until 24 September 2021 for English language, human studies from 1980. Search terms were used for the concepts of natural conception pregnancy, assisted reproduction, and livebirth.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The inclusion criterion was studies with an outcome measure of the proportion of women experiencing natural conception pregnancy after an ART livebirth. Quality of studies was assessed using the Critical Appraisal Skills Programme cohort study checklist or AXIS Appraisal tool for cross-sectional studies, and a risk of bias assessment was carried out. No studies were excluded based on quality. Random-effects meta-analyses were adopted to produce a pooled effect estimate of the proportion of natural conception pregnancy after ART livebirth.

MAIN RESULTS AND THE ROLE OF CHANCE

A total of 1108 distinct studies were identified, resulting in 54 studies after screening by title and abstract. Eleven studies including 5180 women were selected for this review. The included studies were mostly of moderate quality with a maximum follow-up period ranging from 2 to 15 years. Four studies reported natural conception livebirths which were used as known underestimates of natural conception pregnancies. The pooled estimate for the proportion of women having natural conception pregnancies after ART livebirth was 0.20 (95% CI, 0.17-0.22).

LIMITATIONS, REASONS FOR CAUTION

The studies varied widely according to methodology, population, cause of subfertility, type and outcome of fertility treatment, and length of follow-up, leading to potential bias relating to confounding, selection bias, and missing data.

WIDER IMPLICATIONS OF THE FINDINGS

Current evidence suggests that contrary to widely held views, natural conception pregnancy after ART livebirth is far from rare. National, data-linked studies are needed to provide more accurate estimates of this incidence and analysis of associated factors and trends over time to facilitate tailored counselling of couples considering further ART.

STUDY FUNDING/COMPETING INTEREST(S)

This work was conducted as part of an academic clinical fellowship awarded to AT by the National Institute for Health Research (NIHR). NIHR has had no input into the study design, data collection, and analysis, nor the writing of this study. No authors have any conflicts of interest.

Addressing reproductive health needs across the life course: an integrated, community-based model combining contraception and preconception care

Prevention of pregnancy (contraception) and preparation for pregnancy (preconception care) are services that most people need during their reproductive life course. Despite increased attention, and growing recognition that health before pregnancy is crucial to addressing disparities in maternity outcomes, service provision is far from routine. We bring together evidence from the literature, new quantitative and qualitative data on women's preferences, and case studies of existing practice, to develop an integrated, community-based model that synthesises reproductive life planning, contraception, and preconception care. Our model provides a holistic, life course approach, encompassing school-based education, social media, and national campaigns, and highlights the need for training and system-level support for the range of health-care professionals who can deliver it. This high-level model can be adapted across settings, leading to a step change in the provision of preconception care in the community with consequent improvements in health and wellbeing, and reductions in inequalities at population level.

Emotional experiences of women who access early pregnancy assessment units: a qualitative investigation

Purpose: Early pregnancy complications are common and often result in pregnancy loss, which can be emotionally challenging for women. Research on the emotional experiences of those attending Early Pregnancy Assessment Units [EPAUs] is scarce. This analysis explored the emotions which women spontaneously reported when being interviewed about their experiences of using EPAU services.Materials and methods: Semi-structured telephone interviews were conducted with a purposive sample of 38 women. Using Thematic Framework Analysis, we identified six unique emotional typologies which mapped onto women's clinical journeys.Results: Women with ongoing pregnancies were characterized as having: "Anxious Presentation" or "Sustained Anxiety due to Diagnostic Uncertainty", dependent on whether their initial scan result was inconclusive. Women with pregnancy loss had one of four emotional typologies, varying by diagnostic timing and required interventions: "Anxious-Upset"; "Anxious-Upset after Diagnostic Uncertainty"; "Anxious-Upset with Procedural Uncertainty"; "Anxious with Sustained Uncertainty".Conclusions: We provide insights into the distinct emotions associated with different clinical pathways through EPAU services. Our findings could be used to facilitate wider recognition of women's emotional journeys through early pregnancy complications and stimulate research into how best to support women and their partners, in these difficult times.

Measures of Pregnancy Intention: Why Use Them and What Do They Tell Us?

Understanding pregnancy intention is an important public health measure that captures the ability of individuals to access information, resources, and services needed to plan the timing and spacing of pregnancies. Pregnancy intention is a complex construct impacted by social, emotional, financial, cultural, and contextual factors. In this review, we will examine the range of available tools for individuals and populations to evaluate pregnancy intention, the timing of the tools in relation to pregnancy, their interpretation, and use for policy and practice. Traditionally, pregnancy intention was only assessed in population health surveys; however, more sophisticated tools and measures have been developed. These tools can be used at several time points: before pregnancy, during pregnancy, or after the pregnancy has ended. It is important to appreciate the varied contexts globally for women and their partners when assessing pregnancy intention, and the ability of a given tool to capture this when used retrospectively or prospectively. These tools can inform targeted delivery of services for a person or couple before, during, and after pregnancy. This knowledge can inform strategies at an individual, community, and population level as an indicator of access to sexual and reproductive health information and knowledge and uptake of preconception health.

What does family building mean? A qualitative exploration and a new definition: a UK-based study

Background

The importance of improving men’s and women’s knowledge of sexual and reproductive health has been emphasised in numerous global health policies. Fertility awareness literature highlights a disproportionately higher number of articles related to pregnancy-prevention compared to pregnancy-planning, which is justifiable in many contexts. However, recent concerted effort to improve fertility-awareness warrants a closer investigation of basic reproductive health terminologies. The objective of this study is to explore participants’ views of “family building” and provide a definition.

Methods

We conducted 35 qualitative in-depth interviews on men, women and healthcare professionals who were sampled from a UK cross-sectional survey. We asked participants about terms such as ‘family planning’ and ‘family building’ to elicit views and explored the appropriateness of the term “family building.” Data were transcribed and analysed via Framework analysis.

Results

When asked what ‘family planning’ meant to them, study participants stated that the term meant the avoidance of pregnancy. They viewed it as an “umbrella term for the use of contraception methods,” that “paradoxically, the term family planning almost has a negative connotation regarding having a family,” but could not state similar terminology for planning a family. Reasons cited for this perspective include the focus of school education and usage in clinical settings.

Conclusions

In the absence of an explicit definition in literature, we generated a new definition for family building as follows: “Family building refers to the construction or formation of a family, which can include steps or actions taken by an individual towards having children. In contrast to family planning, the intent focuses on pregnancy planning and childbearing rather than pregnancy prevention. However, it can also include actions taken to space the number of children one has.” Some balance in the global public health messages, including bridging the gap in reproductive health literature, policies, processes and practices may contribute to the effort to improve fertility knowledge. Use of appropriate terminologies help optimise reproductive health services in order to enable men and women achieve their desired fertility intentions, whatever they may be.

Trial registration Not applicable

Global health policies have emphasised the importance of improving individual’s knowledge of sexual and reproductive health. Fertility awareness literature highlights a disproportionately higher number of articles related to pregnancy-prevention compared to pregnancy-planning, which is justifiable in many contexts. However, the recent concerted effort to improve fertility awareness warrants a closer investigation of basic terminologies in the field. For example, although the term family planning encompasses attaining the desired number of children and spacing pregnancies, it is almost synonymous with not having children, while there is currently no widely accepted equivalent terminology for planning to have children, either in general usage or clinical settings. We conducted 35 qualitative in-depth interviews on men, women and healthcare professionals who were sampled from a UK cross-sectional survey. When asked what ‘family planning’ meant to them, study participants stated avoidance of pregnancy. They viewed it as an “umbrella term for the use of contraception methods”, that “paradoxically, the term family planning almost has a negative connotation regarding having a family,” but could not state similar terminology for planning a family. We introduced family building and provided a new definition. We believe that some balance in the global public health messages, including revisiting widely used terminologies can help bridge the gap in reproductive health literature, and contribute to the effort to improve fertility knowledge. Additionally, this has implications for promotion of preconception and optimising reproductive health in relevant policies, processes and practices, in order to help people achieve their desired fertility intentions, whatever they may be.

Evaluation of the Desire to Avoid Pregnancy Scale in the UK: a psychometric analysis including predictive validity

OBJECTIVES

To evaluate the psychometric performance, including predictive validity, of a UK version of the Desire to Avoid Pregnancy (DAP) scale.

DESIGN

Prospective cohort study for psychometric evaluation.

SETTING

UK.

PARTICIPANTS

Women in the UK aged 15 years to menopause, who were not pregnant at the time of recruitment in October 2018, were eligible. 994 women completed the baseline survey and 90.2% of women eligible for the 12-month survey participated.

PRIMARY AND SECONDARY OUTCOME MEASURES

The DAP scale was assessed according to key measurement properties of validity (construct (structural and hypothesis testing) and criterion (predictive)), reliability (internal consistency using Cronbach's alpha and test-retest using intraclass correlation coefficients, ICC) and differential item functioning. Item response and classical test theory methods were used.

RESULTS

The scale was acceptable, understandable and showed good targeting with the full range of scores captured. Construct validity was demonstrated on hypothesis testing, with odds of contraceptive use increasing threefold with each increasing DAP point (range: 0-4). Eighty per cent of women with the lowest DAP score became pregnant within 12 months, compared with <1% of those with the highest DAP score. Reliability, both in terms of internal consistency (Cronbach's α 0.96) and test-retest (ICC 0.95), was excellent. Some tests of structural validity, in relation to model fit with the item-response model, were not met, and investigations suggest further exploration of the factor structure of the DAP is required in other samples. Item 5, regarding relationship with a partner, showed differential item functioning by age, number of children and relationship group.

CONCLUSIONS

The UK DAP is a valid and reliable measure of women's DAP and is highly predictive of pregnancy within the next 12 months. Further evaluations should continue the assessment of the factor structure and the performance of the item relating to the partner.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

BACKGROUND

Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications.

METHODS

We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC).

FINDINGS

In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]).

INTERPRETATION

In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required.

P-734 How common is spontaneous pregnancy after In vitro Fertilisation (IVF) Livebirth? Systematic review and meta-analysis

Study question

How common is spontaneous pregnancy after IVF resulting in livebirth? How can this evidence inform future pregnancy planning by women who have successful IVF?

Summary answer

Current evidence suggests that spontaneous pregnancy occurs in at least one in five women in the first three years after having a baby via IVF.

What is known already

It is known that some women having IVF go on to conceive naturally. This reproductive history is of media interest often described as “miracle” pregnancies (1). Women with this experience also identify themselves as a rarity, and their subsequent pregnancies include rapid-repeat, unplanned and unwelcomed pregnancies (2).

Study design, size, duration

An initial scoping review revealed few, heterogeneous studies reporting rates of spontaneous pregnancy or livebirth after successful IVF. These studies suggested that this event is not rare, prompting this first systematic review and meta-analysis. This aims to identify, appraise and synthesise the current evidence on the rate of spontaneous pregnancy after successful IVF.

Participants/materials, setting, methods

Ovid Medline, Embase and PsycINFO were searched on 24/09/2021 using a strategy containing thesaurus and free text terms for the concepts of spontaneous pregnancy, assisted reproduction and livebirth. The search was limited to English language, human studies and publications from 1980. Results were de-duplicated and managed in EndNote, screened by title/abstract and then full text. Random-effects meta-analyses were used to produce a pooled effect estimate of the incidence of spontaneous pregnancy after IVF livebirth.

Main results and the role of chance

1108 distinct references were identified, reducing to 54 when screened by title and abstract. On evaluation of full text, 11 studies were included in this review. Rates of spontaneous pregnancy after IVF livebirth ranged from 10-33% of women. However, studies varied widely according to methodology, population, cause of subfertility, type and outcome of fertility treatment and length of follow-up. Different covariates were investigated and inconsistently found to be associated with spontaneous conception after IVF including younger age, shorter duration of subfertility, fewer number of treatment cycles prior to first delivery and specific causes of subfertility (unexplained, no male factor). The pooled estimate for the rate of spontaneous pregnancy after IVF livebirth was 19% (95% CI, 16%-22%). The pooled estimate was robust when stratifying by IVF/intracytoplasmic sperm injection (ICSI), outcome measure and follow up period. It is a likely underestimate as some studies reported on livebirths (i.e. excluding adverse pregnancy outcomes) and did not include spontaneous births that occurred outside of the study region. Moreover, no studies gave due consideration to contraception, plannedness of pregnancies, change in partner, nor serial spontaneous pregnancies in the same woman.

Limitations, reasons for caution

The current evidence is relatively scarce and diverse. Sample sizes are typically small with only two studies of over a thousand women. Better evidence, in the form of national, data-linked studies, is needed to provide more accurate estimates of this rate, analysis of associated factors and trends over time.

Wider implications of the findings

These findings refute a widely held misconception that spontaneous pregnancy after IVF livebirth is a rare phenomenon. They should be used to counsel women having babies via IVF and inform their decision-making regarding the timing and mode of conception of future pregnancies and contraception use.

Contraception after in vitro fertilisation (IVF): a qualitative study of the views of women who have had spontaneous pregnancies after successful IVF

Background

The use of in vitro fertilisation (IVF) has increased rapidly since its inception in 1978. Women seeking IVF have a wide range of subfertility causes including unexplained subfertility. A growing subgroup of women seek treatment for other reasons than fertility problems, for example, women in same sex relationships and single women. This study aims to better understand the contraceptive needs of women after successful IVF pregnancy in order to improve service delivery and prevent unplanned and rapid-repeat pregnancies.

Methods

A qualitative study of views of women who have had spontaneous pregnancies after successful IVF. Participants were recruited using purposive and snowballing sampling methods from social media and peer networks. The framework method was used for analysis using NVivo12.

Results

The sample comprised 21 interviewees from the United Kingdom (UK), having a range of spontaneous pregnancy outcomes, including single and multiple livebirths, miscarriage, ectopic pregnancy and termination of pregnancy. Contraceptive choices were subject to a complex and dynamic interaction of influencing factors including beliefs regarding subfertility, desire for children and views on contraception. None of the women recalled receiving any information or useful counselling about contraception during fertility or maternity care. After IVF pregnancy, most women (n = 16) used no or ineffective contraception. Spontaneous pregnancy was not universally welcomed in this group and inter-pregnancy intervals were often short (n = 16, less than 18 months). Even after subsequent spontaneous pregnancy, use of contraception and the most effective methods remained low. Women held persistent beliefs regarding their subfertility despite subsequent spontaneous pregnancy. They associated aspects of the IVF process with a sense of personal failure, despite an ultimately “successful” outcome of livebirth. These aspects may reinforce their self-belief in subfertility. Other barriers to contraception use in women having IVF included: lack of knowledge of likelihood of spontaneous pregnancy, lack of contraceptive experience and inherent incentives towards shorter inter-pregnancy intervals.

Conclusions

The contraceptive needs of women having IVF pregnancies are real and are being overlooked. Fertility services should take responsibility for providing information on the risks of subsequent spontaneous pregnancy. Maternity and community healthcare professionals must address women’s perceptions of their fertility in order to engage them in contraception counselling.

Evaluation of the Portuguese version of the London measure of unplanned pregnancy in Mozambique: A psychometric measurement study

Robust forms of measurement such as the London Measure of Unplanned Pregnancy (LMUP), which recognise the complexity of the construct of pregnancy planning/intention, are being adopted worldwide. The aim of this study was to evaluate the psychometric properties of the Mozambican Portuguese version of the LMUP. The Brazilian Portuguese interviewer-administered LMUP was culturally adapted for use in Mozambique and pre-tested with 28 women. Field testing included 524 women aged 16-42. Completion rates of LMUP items were 100%. LMUP scores 0-12 were captured. In terms of reliability (internal consistency), Cronbach's alpha was 0.90, item-rest correlations were <0.2, and all inter-item correlations were positive. In terms of construct validity, principal components analysis showed that measurement was unidimensional, confirmatory factor analysis showed good model fit, and all hypotheses were met. We conclude that the Mozambican Portuguese LMUP is reliable, valid and suitable to use in Mozambique.

OUP accepted manuscript

STUDY QUESTION

Does maternal infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the first trimester affect the risk of miscarriage before 13 week’s gestation?

SUMMARY ANSWER

Pregnant women with self-reported diagnosis of SARS-CoV-2 in the first trimester had a higher risk of early miscarriage.

WHAT IS KNOWN ALREADY

Viral infections during pregnancy have a broad spectrum of placental and neonatal pathology. Data on the effects of the SARS-CoV-2 infection in pregnancy are still emerging. Two systematic reviews and meta-analyses reported an increased risk of preterm birth, caesarean delivery, maternal morbidity and stillbirth. Data on the impact of first trimester infection on early pregnancy outcomes are scarce. This is the first study, to our knowledge, to investigate the rates of early pregnancy loss during the SARS-CoV-2 outbreak among women with self-reported infection.

STUDY DESIGN, SIZE, DURATION

This was a nationwide prospective cohort study of pregnant women in the community recruited using social media between 21 May and 31 December 2020. We recruited 3545 women who conceived during the SARS-CoV-2 pandemic who were <13 week’s gestation at the time of recruitment.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The COVID-19 Contraception and Pregnancy Study (CAP-COVID) was an on-line survey study collecting longitudinal data from pregnant women in the UK aged 18 years or older. Women who were pregnant during the pandemic were asked to complete on-line surveys at the end of each trimester. We collected data on current and past pregnancy complications, their medical history and whether they or anyone in their household had symptoms or been diagnosed with SARS-CoV-2 infection during each trimester of their pregnancy. RT-PCR-based SARS-CoV-2 RNA detection from respiratory samples (e.g. nasopharynx) is the standard practice for diagnosis of SARS-CoV-2 in the UK. We compared rate of self-reported miscarriage in three groups: ‘presumed infected’, i.e. those who reported a diagnosis with SARS-CoV-2 infection in the first trimester; ‘uncertain’, i.e. those who did not report a diagnosis but had symptoms/household contacts with symptoms/diagnosis; and ‘presumed uninfected’, i.e. those who did not report any symptoms/diagnosis and had no household contacts with symptoms/diagnosis of SARS-CoV-2.

MAIN RESULTS AND THE ROLE OF CHANCE

A total of 3545 women registered for the CAP-COVID study at <13 weeks gestation and were eligible for this analysis. Data for the primary outcome were available from 3041 women (86%). In the overall sample, the rate of self-reported miscarriage was 7.8% (238/3041 [95% CI, 7–9]). The median gestational age (GA) at miscarriage was 9 weeks (interquartile range 8–11). Seventy-seven women were in the ‘presumed infected’ group (77/3041, 2.5% [95% CI 2–3]), 295/3041 were in the uncertain group (9.7% [95% CI 9–11]) and the rest in the ‘presumed uninfected’ (87.8%, 2669/3041 [95% CI 87–89]). The rate of early miscarriage was 14% in the ‘presumed infected’ group, 5% in the ‘uncertain’ and 8% in the ‘presumed uninfected’ (11/77 [95% CI 6–22] versus 15/295 [95% CI 3–8] versus 212/2669 [95% CI 7–9], P = 0.02). After adjusting for age, BMI, ethnicity, smoking status, GA at registration and the number of previous miscarriages, the risk of early miscarriage appears to be higher in the ‘presumed infected’ group (relative rate 1.7, 95% CI 1.0–3.0, P = 0.06).

LIMITATIONS, REASONS FOR CAUTION

We relied on self-reported data on early pregnancy loss and SARS-CoV-2 infection without any means of checking validity. Some women in the ‘presumed uninfected’ and ‘uncertain’ groups may have had asymptomatic infections. The number of ‘presumed infected’ in our study was low and therefore the study was relatively underpowered.

WIDER IMPLICATIONS OF THE FINDINGS

This was a national study from the UK, where infection rates were one of the highest in the world. Based on the evidence presented here, women who are infected with SARS-CoV-2 in their first trimester may be at an increased risk of a miscarriage. However, the overall rate of miscarriage in our study population was 8%. This is reassuring and suggests that if there is an effect of SARS-CoV-2 on the risk of miscarriage, this may be limited to those with symptoms substantial enough to lead to a diagnostic test. Further studies are warranted to evaluate a causal association between SARS-CoV-2 infection in early pregnancy and miscarriage risk. Although we did not see an overall increase in the risk of miscarriage, the observed comparative increase in the presumed infected group reinforces the message that pregnant women should continue to exercise social distancing measures and good hygiene throughout their pregnancy to limit their risk of infection

Impact of the SARS-CoV-2 pandemic on access to contraception and pregnancy intentions: a national prospective cohort study of the UK population

OBJECTIVE

Evaluate the impact of the COVID-19 pandemic on access to contraception and pregnancy intentions.

DESIGN

Nationwide prospective cohort study.

SETTING

United Kingdom.

PARTICIPANTS

Women in the UK who were pregnant between 24 May and 31 December 2020.

MAIN OUTCOME MEASURES

Access to contraception and level of pregnancy intentions, using the London Measure of Unplanned Pregnancy (LMUP) in women whose last menstrual period was before or after 1 April 2020. While the official date of the first UK lockdown was 23 March, we used 1 April to ensure that those in the post-lockdown group would have faced restrictions in the month that they conceived.

RESULTS

A total of 9784 women enrolled in the cohort: 4114 (42.0%) conceived pre-lockdown and 5670 (58.0%) conceived post-lockdown. The proportion of women reporting difficulties accessing contraception was higher in those who conceived after lockdown (n=366, 6.5% vs n=25, 0.6%, p<0.001) and continued to rise from March to September 2020. After adjusting for confounders, women were nine times more likely to report difficulty accessing contraception after lockdown (adjusted odds ratio (aOR) 8.96, 95% CI 5.89 to 13.63, p<0.001). There is a significant difference in the levels of pregnancy planning, with higher proportions of unplanned (n=119, 2.1% vs n=55, 1.3%) and ambivalent pregnancies (n=1163, 20.5% vs n=663, 16.1%) and lower proportions of planned pregnancies (n=4388, 77.4% vs n=3396, 82.5%) in the post-lockdown group (p<0.001). After adjusting for confounders, women who conceived after lockdown were still significantly less likely to have a planned pregnancy (aOR 0.88, 95% CI 0.79 to 0.98, p=0.025).

CONCLUSIONS

Access to contraception in the UK has become harder during the COVID-19 pandemic and the proportion of unplanned pregnancies has almost doubled.

Differences in the organisation of early pregnancy units and the effect of senior clinician presence, volume of patients and weekend opening on emergency hospital admissions: Findings from the VESPA Study

OBJECTIVE

To determine whether the participation of consultant gynaecologists in delivering early pregnancy care results in a lower rate of acute hospital admissions.

DESIGN

Prospective cohort study and emergency hospital care audit; data were collected as part of the national prospective mixed-methods VESPA study on the "Variations in the organization of EPAUs in the UK and their effects on clinical, Service and PAtient-centred outcomes".

SETTING

44 Early Pregnancy Assessment Units (EPAUs) across the UK randomly selected in balanced numbers from eight pre-defined mutually exclusive strata.

PARTICIPANTS

6606 pregnant women (≥16 years old) with suspected first trimester pregnancy complications attending the participating EPAUs or Emergency Departments (ED) from December 2016 to July 2017.

EXPOSURES

Planned and actual senior clinician presence, unit size, and weekend opening.

MAIN OUTCOME MEASURES

Unplanned admissions to hospital following any visit for investigations or treatment for first trimester complications as a proportion of women attending EPAUs.

RESULTS

205/6397 (3.2%; 95% CI 2.8-3.7) women were admitted following their EPAU attendance. The admission rate among 44 units ranged from 0% to 13.7% (median 2.8). Neither planned senior clinician presence (p = 0.874) nor unit volume (p = 0.247) were associated with lower admission rates from EPAU, whilst EPAU opening over the weekend resulted in lower admission rates (p = 0.027). 1445/5464 (26.4%; 95%CI 25.3 to 27.6) women were admitted from ED. There was little evidence of an association with planned senior clinician time (p = 0.280) or unit volume (p = 0.647). Keeping an EPAU open over the weekend for an additional hour was associated with 2.4% (95% CI 0.1% to 4.7%) lower odds of an emergency admission from ED.

CONCLUSIONS

Involvement of senior clinicians in delivering early pregnancy care has no significant impact on emergency hospital admissions for early pregnancy complications. Weekend opening, however, may be an effective way of reducing emergency admissions from ED.

Women's experiences of early pregnancy assessment unit services: a qualitative investigation

OBJECTIVE

To explore the experiences of women who had used an Early Pregnancy Assessment Unit (EPAU) service in the UK and make recommendations for their improvement.

DESIGN

Qualitative interview study.

SETTING

Early Pregnancy Assessment Units in the UK.

SAMPLE

A maximum variation sample of women who had consented to be interviewed having attended one of 26 EPAUs involved in the VESPA study in 2018.

METHODS

In-depth telephone interviews with 38 women. A thematic framework analysis was conducted, with a focus on how experiences varied according to EPAU service configuration and clinical pathway.

MAIN OUTCOME MEASURES

Women's experiences of EPAU services.

RESULTS

We found that EPAUs are highly valued, and women's experiences were generally positive. However, women reported a range of issues that negatively affected their experience. These included difficulties accessing the service, insensitive management of the investigation and treatment options of pregnancy loss, poor communication, insufficient information and a lack of support for their psychological health. These issues were not strongly associated with EPAU configuration or clinical pathway.

CONCLUSIONS

Recommendations to improve women's experiences include the separation of EPAUs from general maternity services, and we make suggestions on how to remove barriers to access by reviewing opening hours, how to provide sensitive patient management, such as automatically cancelling appointments and scans following pregnancy loss, and how to improve communication, both with women and their partners as well as with other parts of the health service.

Evaluating the Chichewa version of the London Measure of Unplanned Pregnancy in Malawi: a validation update

Objective

To investigate the psychometric properties of the validated Chichewa version of the London Measure of Unplanned Pregnancy in a large representative community-based sample in Malawi, a low-income country. We collected data on pregnancy intention from a cohort of 4244 pregnant women in Malawi using the validated Chichewa version of the London Measure of Unplanned Pregnancy (LMUP). We evaluated the psychometric properties of the Chichewa LMUP using classical test theory and confirmatory factor analysis to re-assess the performance of items one and six, which had weaker performance in the original smaller, facility-based validation sample.

Results

The Chichewa version of the LMUP met all pre-set criteria for validation. There are now nine validations of the LMUP in different low-and-middle-income countries, confirming the validity and applicability of the LMUP in these settings.

Variations in the organisation of and outcomes from Early Pregnancy Assessment Units: the VESPA mixed-methods study

Background

Early pregnancy complications are common and account for the largest proportion of emergency work in gynaecology. Although early pregnancy assessment units operate in most UK acute hospitals, recent National Institute of Health and Care Excellence guidance emphasised the need for more research to identify configurations that provide the optimal balance between cost-effectiveness, clinical effectiveness and service- and patient-centred outcomes [National Institute for Health and Care Excellence (NICE). Ectopic Pregnancy and Miscarriage: Diagnosis and Initial Management. URL: http://guidance.nice.org.uk/CG154 (accessed 23 March 2016)].

Objectives

The primary aim was to test the hypothesis that the rate of hospital admissions for early pregnancy complications is lower in early pregnancy assessment units with high consultant presence than in units with low consultant presence. The key secondary objectives were to assess the effect of increased consultant presence on other clinical outcomes, to explore patient satisfaction with the quality of care and to make evidence-based recommendations about the future configuration of UK early pregnancy assessment units.

Design

The Variations in the organisations of Early Pregnancy Assessment Units in the UK and their effects on clinical, Service and PAtient-centred outcomes (VESPA) study employed a multimethods approach and included a prospective cohort study of women attending early pregnancy assessment units to measure clinical outcomes, an economic evaluation, a patient satisfaction survey, qualitative interviews with service users, an early pregnancy assessment unit staff survey and a hospital emergency care audit.

Setting

The study was conducted in 44 early pregnancy assessment units across the UK.

Participants

Participants were pregnant women (aged ≥ 16 years) attending the early pregnancy assessment units or other hospital emergency services because of suspected early pregnancy complications. Staff members directly involved in providing early pregnancy care completed the staff survey.

Main outcome measure

Emergency hospital admissions as a proportion of women attending the participating early pregnancy assessment units.

Methods

Data sources – demographic and routine clinical data were collected from all women attending the early pregnancy assessment units. For women who provided consent to complete the questionnaires, clinical data and questionnaires were linked using the women’s study number. Data analysis and results reporting – the relationships between clinical outcomes and consultant presence, unit volume and weekend opening hours were investigated using appropriate regression models. Qualitative interviews with women, and patient and staff satisfaction, health economic and workforce analyses were also undertaken, accounting for consultant presence, unit volume and weekend opening hours.

Results

We collected clinical data from 6606 women. There was no evidence of an association between admission rate and consultant presence (p = 0.497). Health economic evaluation and workforce analysis data strands indicated that lower-volume units with no consultant presence were associated with lower costs than their alternatives.

Limitations

The relatively low level of direct consultant involvement could explain the lack of significant impact on quality of care. We were also unable to estimate the potential impact of factors such as scanning practices, level of supervision, quality of ultrasound equipment and clinical care pathway protocols.

Conclusions

We have shown that consultant presence in the early pregnancy assessment unit has no significant impact on key outcomes, such as the proportion of women admitted to hospital as an emergency, pregnancy of unknown location rates, ratio of new to follow-up visits, negative laparoscopy rate and patient satisfaction. All data strands indicate that low-volume units run by senior or specialist nurses and supported by sonographers and consultants may represent the optimal early pregnancy assessment unit configuration.

Future work

Our results show that further research is needed to assess the potential impact of enhanced clinical and ultrasound training on the performance of all disciplines working in early pregnancy assessment units.

Evaluation of the Psychometric Properties of a Version of the London Measure of Unplanned Pregnancy for Women’s Partners

BackgroundThe role of women’s partners in pregnancy planning has gained importance with the development of preconception care. The measurement of pregnancy planning/intention has also changed in the last two decades with the development of psychometric measures such as the London Measure of Unplanned Pregnancy (LMUP). This analysis aimed to evaluate the psychometric properties of a version of the LMUP for women’s partners in the UK. MethodsThe LMUP items, adapted for completion by partners, were piloted and included in a survey of (mainly male) partners in three antenatal clinics in London, UK, as part of a study of pre-pregnancy health and care. The psychometric properties of the partner LMUP were assessed according to the principles of Classical Test Theory. ResultsThere were 575 partners of pregnant women in the sample, 573 (99.7%) being men. There were high comple-tion rates for all the LMUP items. The distribution of LMUP scores ranged from 1–12, with a negative skew (biased towards planned/intended pregnancies). In terms of reliability (internal consistency), Cronbach’s alpha was 0.69, item-rest correlations were >0.2 for five items, and all inter-item correlations were positive. In terms of construct validity, principal components analysis showed that measurement was unidimensional, confirmatory factor analysis showed good model fit, and the convergent validity hypothesis of non-perfect, moderate-to-good agreement between couples’ LMUP scores was met. ConclusionsThe partner LMUP performed well in terms of reliability and validity according to internationally-accepted criteria for the performance of psychometric measures and can be used in future research on men and couples. However, we recommend further research relating to the concept of pregnancy planning/inten-tion among partners of all gender identities to understand whether additional content would enhance the measurement of the construct. In particular, we recommend further conceptual exploration with men who have experienced unplanned pregnancies.  

Evaluation of the Krio Language Version of the London Measure of Unplanned Pregnancy in Western Area, Sierra Leone

New ways of measuring pregnancy planning/intention such as the London Measure of Unplanned Pregnancy (LMUP), which recognise the complexity of the construct, are being adopted worldwide. The aim of this study was to evaluate the psychometric properties of the Krio version of the LMUP in Sierra Leone. An interviewer-administered version of the LMUP was translated into Krio and pre-tested with 12 pregnant women. Field testing involved 172 pregnant women aged 15-42, with 87 completing a re-test. Completion rates of LMUP items were 100%. LMUP scores 1-12 were captured. Reliability: the scale was internally consistent (Cronbach's alpha 0.84) and stable (weighted Kappa 0.93). Construct validity: all hypotheses were confirmed. Principal components analysis revealed five items (items 2-6) related to one construct. Mokken scaling procedure selected the same five items. Removal of item 1 (which had 97% endorsement of the ‗no contraception' response option) brought about only a very slight improvement in LMUP performance, therefore we recommend retaining all six items. The Krio LMUP is reliable, valid and suitable to use in Sierra Leone.

Opportunities for enhancing pregnancy planning and preconception health behaviours of Australian women

PROBLEM AND BACKGROUND

The preconception period provides a significant opportunity to engage women in healthy behaviour change for improved maternal and child health outcomes. However, there is limited research exploring women's pregnancy planning in Australia.

AIM

This study investigated associations between pregnancy planning, socio-demographics and preconception health behaviours in Australian women.

METHODS

A retrospective cross-sectional survey of pregnant women ≥18-years-of-age recruited through a Victorian public maternity service and a national private health insurer.

RESULTS

Overall 317 women (30±4.7 years) participated (public: n=225, private: n=92). Planned pregnancies were reported by 74% of women and were independently associated with marital status (AOR=5.71 95% CI 1.92-17.00, p=0.002); having ≤2 children (AOR=3.75 95% CI 1.28-11.05, p=0.016); and having private health insurance (AOR=2.51 95% CI 1.08-5.81, p=0.03). Overall, women reported preconception: any folic-acid supplementation (59%), up-to-date cervical screening (68%), weight management attempts (75%), accessing information from health professionals (57%) and immunisation reviews (47%). Pregnancy planners were more likely to use folic-acid (AOR=17.13 95% CI 7.67-38.26, p<0.001), review immunisations (AOR=2.09 95% CI 1.07-4.10, p=0.03) and access information (AOR=3.24 95% CI 1.75-6.00, p<0.001) compared to non-planners. Women <25-years-of-age were less likely to access information (AOR=0.38 95% CI 0.16-0.89, p=0.03) and take folic-acid (AOR=0.23 95% CI 0.09-0.59, p=0.002) and were more likely to smoke 3-months preconception (AOR=6.68 95% CI 1.24-36.12, p=0.03).

CONCLUSIONS

Women with planned and unplanned pregnancies reported variable preconception health behaviour uptake and limited healthcare engagement. Opportunities exist to improve awareness and healthcare engagement for optimising preconception health and pregnancy planning benefits including collaborative health promotion. Population-based and targeted approaches reaching pregnancy planners and non-planners are required.

Pregnancy Planning among Female Sex Workers in Uganda: Evaluation of the Psychometric Properties of the London Measure of Unplanned Pregnancy

The aim of the study was to evaluate the psychometric properties of the London Measure of Unplanned Pregnancy (LMUP) among female sex workers (FSWs) in Uganda. The LMUP was translated into Luganda and adapted for use with FSWs and underwent cognitive testing and two field tests. From the final Luganda LMUP, three other language versions were created (Acholi, Lugisu and Runyakole), and preliminary field test data were collected. Final data were collected from 819 FSWs attending the 'Most at Risk Population Initiative' clinics. The Luganda field testing showed that there were no missing data, the scale was well targeted, Cronbach's alpha was 0.82, weighted Kappa was 0.78, measurement was unidimensional, and all construct validity hypotheses were met. Likewise, with the Acholi, Lugisu, and Runyankole translations, field testing showed that there were no missing data, the scales were well targeted, Cronbach's alpha were<0.70, and measurement was unidimensional. We concluded that the Luganda LMUP is a valid and reliable tool for assessing pregnancy planning among FSWs in Uganda and that the Acholi, Lugisu, and Runyankole versions of the LMUP also had good initial psychometric properties.

Determination of Ochratoxin A in Currants, Raisins, Sultanas, Mixed Dried Fruit, and Dried Figs by Immunoaffinity Column Cleanup with Liquid Chromatography: Interlaboratory Study

An interlaboratory study was performed on behalf of the Food Standards Agency to evaluate the effectiveness of an affinity column cleanup liquid chromatographic (LC) method for the determination of ochratoxin A in a variety of dried fruit at European regulatory limits. To ensure homogeneity before analysis, laboratory samples are normally slurried with water in the ratio of 5 parts fruit to 4 parts water, and test materials in this form were used in the study. The test portion was extracted with acidified methanol. The extract was filtered, diluted with phosphate-buffered saline, and applied to an affinity column. The column was washed and ochratoxin A was eluted with methanol. Ochratoxin A was quantified by reversed-phase LC. The use of post-column pH shift to enhance the fluorescence of ochratoxin A by the addition of 1.1M ammonia solution to the column eluant is optional. Determination was by fluorescence. Currants, sultanas, raisins, figs, and mixed fruit (comprising dried pineapple, papaya, sultanas, prunes, dates, and banana chips), both naturally contaminated and blank (very low level), were sent to 24 collaborators in 7 European countries. Participants were asked to spike test portions of all test samples at a level equivalent to 5 ng/g ochra toxin A. Average recoveries ranged from 69 to 74%. Based on results for 5 naturally contaminated test samples (blind duplicates) the relative standard deviation for repeatability (RSDr) ranged from 4.9 to 8.7%, and the relative standard deviation for reproducibility (RSDR)rangedfrom14to28%. The method showed acceptable within-and be-tween-laboratory precision for all 5 matrixes, as evidenced by HORRAT values &lt;1.3.

On the Stability of Reported Pregnancy Intentions from Pregnancy to 1 Year Postnatally: Impact of Choice of Measure, Timing of Assessment, Women's Characteristics and Outcome of Pregnancy

OBJECTIVES

Retrospective, cross-sectional estimates of pregnancy intention, as used in the Demographic Health Survey (DHS), are the global norm. The London Measure of Unplanned Pregnancy (LMUP) is a newer, psychometrically validated measure which may be more reliable. This paper assesses the reliability of the LMUP and the DHS question over the first postnatal year and explores the effects of maternal characteristics or pregnancy outcome on reported pregnancy intention.

METHODS

We compared the test-retest reliability of the LMUP (using the AC coefficient) and DHS question (using the weighted Kappa) over the first postnatal year using data from Malawian women. We investigated the effect of maternal characteristics and pregnancy outcome using t-tests, Chi squared or Fisher's exact tests, and calculated odds ratios to estimate effect size.

RESULTS

The DHS question was associated with a statistically significant decrease in the prevalence of unplanned pregnancies from 1-to-12 months postnatally; the LMUP was not. The LMUP had moderate to substantial reliability (0.51-0.66); the DHS had moderate reliability (0.56-0.58). The LMUP's stability was not related to any of the factors examined; the stability of the DHS varied by marital status (p = 0.033), number of children (p = 0.048) and postnatal depression (p < 0.001). Both underestimated unintended pregnancy postnatally vis-à-vis the LMUP in pregnancy.

CONCLUSIONS FOR PRACTICE

The LMUP is a more reliable measure of pregnancy intention than the DHS in the first postnatal year and does not vary by maternal characteristics or pregnancy outcome. The LMUP should become the gold-standard for measuring pregnancy intention and should be collected in pregnancy or at the first postnatal opportunity.

Validation of the London Measure of Unplanned Pregnancy among pregnant Australian women

Introduction

Globally, over half of pregnancies in developed countries are unplanned. Identifying and understanding the prevalence and complexity surrounding pregnancy preparation among Australian women is vital to enable sensitive, responsive approaches to addressing preconception and long-term health improvements for these women with varying motivation levels.

Aim

This study evaluated the reliability and validity of a comprehensive pregnancy planning/intention measure (London Measure of Unplanned Pregnancy) in a population of pregnant women (over 18 years of age) in Australia.

Methods

A psychometric evaluation, within a cross-sectional study comprising cognitive interviews (to assess comprehension and acceptability) and a field test. Pregnant women aged over 18 years were recruited in early pregnancy (approximately 12 weeks’ gestation). Reliability (internal consistency) was assessed using Cronbach’s alpha, corrected item-total correlations and inter-item correlations, and stability via a test-retest. Construct validity was assessed using principal components analysis and hypothesis testing.

Results

Six women participated in cognitive interviews and 317 in the field test. The London Measure of Unplanned Pregnancy was acceptable and well comprehended. Reliability testing demonstrated good internal consistency (alpha = 0.81, all corrected item-total correlations >0.20, all inter-item correlations positive) and excellent stability (weighted kappa = 0.92). Validity testing confirmed the unidimensional structure of the measure and all hypotheses were confirmed.

Conclusions

The London Measure of Unplanned Pregnancy is a valid and reliable measure of pregnancy planning/intention for the Australian population. Implementation of this measure into all maternity healthcare, research and policy settings will provide accurate population-level pregnancy planning estimates to inform, monitor and evaluate interventions to improve preconception health in Australia.

Preconception health in England: a proposal for annual reporting with core metrics

There is growing interest in preconception health as a crucial period for influencing not only pregnancy outcomes, but also future maternal and child health, and prevention of long-term medical conditions. Successive national and international policy documents emphasise the need to improve preconception health, but resources and action have not followed through with these goals. We argue for a dual intervention strategy at both the public health level (eg, by improving the food environment) and at the individual level (eg, by better identification of those planning a pregnancy who would benefit from support to optimise health before conception) in order to raise awareness of preconception health and to normalise the notion of planning and preparing for pregnancy. Existing strategies that target common risks factors, such as obesity and smoking, should recognise the preconception period as one that offers special opportunity for intervention, based on evidence from life-course epidemiology, developmental (embryo) programming around the time of conception, and maternal motivation. To describe and monitor preconception health in England, we propose an annual report card using metrics from multiple routine data sources. Such a report card should serve to hold governments and other relevant agencies to account for delivering interventions to improve preconception health.

Contraceptive use, prevalence and predictors of pregnancy planning among female sex workers in Uganda: a cross sectional study

BACKGROUND

Unintended pregnancies are associated with negative consequences to both mother and baby. Female Sex Workers (FSWs) are at high risk of unintended/unplanned pregnancies. However, prevalence of pregnancy planning and its predictors among FSWs has not been comprehensively investigated. This study was designed to determine contraceptive use, the prevalence, and predictors of pregnancy planning among FSWs in Uganda.

METHODS

In this cross-sectional study, 819 FSWs attending most at risk populations initiative (MARPI) clinics were recruited using systematic sampling and interviewed with a pretested questionnaire that included collection of data on pregnancy intention using the London Measure of Unplanned Pregnancy (LMUP). Data were analysed using STATA version 14.0. Multinomial logistic regression model was used to identify predictors of pregnancy planning, RESULTS: Of the 819 study participants, only 90 (11.0%) had planned pregnancies. Overall, 462 (56.4%) were hazardous alcohol users and 335 (40.9%) abused drugs; 172 (21.0%) had been raped in the last 2 years and 70 (40.7%) of these accessed emergency contraception post-rape. Dual contraception use (condom and other modern method) was 58.0%. Having a non-emotional partner as a man who impregnated the FSW compared to emotional partner was significantly associated with less planned relative to unplanned pregnancy, (aRR = 0.15 95%Cl =0.08, 0.30), so was lack of reported social support compared to support from friends, (aRR = 0.44; 95% CI = 0.22-0.87), keeping all factors constant in the model. Being raped (aRR = 0.51; 95% CI = 0.31-0.84) or abuse of substances (aRR = 0.65; 95% CI = 0.45-0.93) were significantly associated with lower ambivalence relative to unplanned pregnancy but not with planned relative to unplanned pregnancy.

CONCLUSION

Compared to women in the general population, pregnancy planning was low among FSWs amidst modest use of dual contraceptive. There is an urgent need to promote dual contraception among FSWs to prevent unplanned pregnancies especially with non-emotional partners, drug users, and post-rape.

Preparation for fatherhood: A survey of men's preconception health knowledge and behaviour in England

Methods

A cross-sectional survey of men attending antenatal care with their partners at three London Maternity Units. We assessed level of pregnancy planning using the partner version of the London Measure of Unplanned Pregnancy (LMUP), preconception health behaviours, and whether they had sought information and health professional advice before conception.

Main results

We recruited 573 men (91% response rate). Mean age was 34 years, 86% were in employment or full time education and 66% had a degree. Half were overweight or obese, 16% were still smoking and 79% had consumed alcohol in the three months before conception. Of 250 men answering questions about medication, a third were taking medication with potentially adverse effects on male reproductive health, while 23% reported taking pre-pregnancy vitamins.

46.9% had looked at information about pregnancy from a variety of sources, including online, before their partner became pregnant. Assessed by the LMUP, 74% of pregnancies were planned. Male ‘planners’ were more likely than other men to reduce smoking, reduce alcohol consumption and to eat more healthily in preparation for pregnancy. However, 57% took no action to improve their health.

Significance of the findings

In a sample of relatively educated men accompanying their partners on an antenatal visit, nearly half had made at least one positive health behaviour change before pregnancy, but half were overweight or obese and a third were on medication that could impair male reproductive health. These findings, together with a high prevalence of alcohol consumption and smoking, indicate the need for greater paternal preconception health awareness and care. Innovative ways to promote positive messages about fatherhood, including medication review as part of preconception care, should be evaluated for impact on improving paternal reproductive health and pregnancy and neonatal outcomes.

Reassessing pregnancy intention and its relation to maternal, perinatal and neonatal outcomes in a low-income setting: A cohort study

BACKGROUND

It is unclear whether unintended pregnancies are associated with adverse outcomes. Data are predominantly from high-income countries and have methodological limitations, calling the findings into question. This research was designed to overcome these limitations and assess the relationships between pregnancy intention and miscarriage, stillbirth, low birthweight, neonatal death and postnatal depression in a low-income country.

METHODS

The pregnancy intention of 4,244 pregnant women in Mchinji District, Malawi, was measured using the validated Chichewa version of the London Measure of Unplanned Pregnancy (LMUP). Women were re-interviewed postnatally to assess pregnancy outcome. Postnatal depression was assessed using the WHO's Self-Reporting Questionnaire. Multivariable regressions were conducted, with the choice of confounders informed by a pre-existing conceptual epidemiological hierarchy.

RESULTS

Planned pregnancies are associated with a reduced risk of any (adjusted RR 0.90 [95%CI 0.86, 0.95]) or high symptoms of depression (adjusted RR 0.76 [95%CI 0.63, 0.91]) compared to unplanned pregnancies in rural Malawi. There was no relationship between pregnancy intention and the composite measure of miscarriage, stillbirth, low birthweight and neonatal death. There was some evidence that greater pregnancy intention was associated with reduced adjusted risk of stillbirth (0·93 [95%CI 0·87, 1·00]).

CONCLUSION

Our study is the first to use a psychometrically valid measure of pregnancy intention, and to do so antenatally. As pregnancy intention increases, the risk of postnatal depression and, possibly, stillbirth decreases. This suggests a new, clinical use for the LMUP; identifying women antenatally who are at risk of these adverse pregnancy outcomes.

Comparing the order of the London Measure of Unplanned Pregnancy and the Demographic and Health Survey question on pregnancy intention in a single group of postnatal women in Malawi - the effect of question order on assessment of pregnancy intention

Objective

To investigate the effect of question order on women’s responses to the London Measure of Unplanned Pregnancy (LMUP) or the pregnancy intention question of the Demographic and Health Survey (DHS) when both are asked in the same survey. We collected data on pregnancy intention from a cohort of 4244 pregnant women in Malawi who were re-interviewed at 1, 6 and 12 months postnatally. Women in Zone 1 were asked the LMUP, then antenatal questions, then the DHS pregnancy intention question, women in Zone 2 were asked the DHS pregnancy intention question, then antenatal questions, then the LMUP; women in Zone 3 were only asked the DHS pregnancy intention question. We used linear regression to compare the LMUP score and ordinal regression to compare DHS categorisations of pregnancy intention across Zones, adjusting for baseline socioeconomic differences between the Zones.

Results

We found no effect of question order on the assessment of pregnancy intention by the LMUP. There were differences in the assessment of pregnancy intention when the pregnancy intention question in the DHS was used, however this seemed to be due to baseline sociodemographic differences between the groups of pregnant women being compared, and not due to question order.

Before the beginning: nutrition and lifestyle in the preconception period and its importance for future health

A woman who is healthy at the time of conception is more likely to have a successful pregnancy and a healthy child. We reviewed published evidence and present new data from low-income, middle-income, and high-income countries on the timing and importance of preconception health for subsequent maternal and child health. We describe the extent to which pregnancy is planned, and whether planning is linked to preconception health behaviours. Observational studies show strong links between health before pregnancy and maternal and child health outcomes, with consequences that can extend across generations, but awareness of these links is not widespread. Poor nutrition and obesity are rife among women of reproductive age, and differences between high-income and low-income countries have become less distinct, with typical diets falling far short of nutritional recommendations in both settings and especially among adolescents. Several studies show that micronutrient supplementation starting in pregnancy can correct important maternal nutrient deficiencies, but effects on child health outcomes are disappointing. Other interventions to improve diet during pregnancy have had little effect on maternal and newborn health outcomes. Comparatively few interventions have been made for preconception diet and lifestyle. Improvements in the measurement of pregnancy planning have quantified the degree of pregnancy planning and suggest that it is more common than previously recognised. Planning for pregnancy is associated with a mixed pattern of health behaviours before conception. We propose novel definitions of the preconception period relating to embryo development and actions at individual or population level. A sharper focus on intervention before conception is needed to improve maternal and child health and reduce the growing burden of non-communicable diseases. Alongside continued efforts to reduce smoking, alcohol consumption, and obesity in the population, we call for heightened awareness of preconception health, particularly regarding diet and nutrition. Importantly, health professionals should be alerted to ways of identifying women who are planning a pregnancy.

Psychometric properties of the Dutch version of the London Measure of Unplanned Pregnancy in women with pregnancies ending in birth

Objective

To evaluate the psychometric properties of the Dutch version of the London Measure of Unplanned Pregnancy in women with pregnancies ending in birth.

Methods

A two-phase psychometric evaluation design was set-up. Phase I comprised the translation from English into Dutch and pretesting with 6 women using cognitive interviews. In phase II, the reliability and validity of the Dutch version of the LMUP was assessed in 517 women giving birth recently. Reliability (internal consistency) was assessed using Cronbach’s alpha, inter-item correlations, and corrected item-total correlations. Construct validity was assessed using principal components analysis and hypothesis testing. Exploratory Mokken scale analysis was carried out.

Results

517 women aged 15–45 completed the Dutch version of the LMUP. Reliability testing showed acceptable internal consistency (alpha = 0.74, positive inter-item correlations between all items, all corrected item-total correlations >0.20). Validity testing confirmed the unidimensional structure of the scale and all hypotheses were confirmed. The overall Loevinger’s H coefficient was 0.57, representing a ‘strong’ scale.

Conclusion

The Dutch version of the LMUP is a reliable and valid measure that can be used in the Dutch-speaking population in Belgium to assess pregnancy planning. Future research is necessary to assess the stability of the Dutch version of the LMUP, and to evaluate its psychometric properties in women with abortions.

London Measure of Unplanned Pregnancy: guidance for its use as an outcome measure

Background

The London Measure of Unplanned Pregnancy (LMUP) is a psychometrically validated measure of the degree of intention of a current or recent pregnancy. The LMUP is increasingly being used worldwide, and can be used to evaluate family planning or preconception care programs. However, beyond recommending the use of the full LMUP scale, there is no published guidance on how to use the LMUP as an outcome measure. Ordinal logistic regression has been recommended informally, but studies published to date have all used binary logistic regression and dichotomized the scale at different cut points. There is thus a need for evidence-based guidance to provide a standardized methodology for multivariate analysis and to enable comparison of results. This paper makes recommendations for the regression method for analysis of the LMUP as an outcome measure.

Materials and methods

Data collected from 4,244 pregnant women in Malawi were used to compare five regression methods: linear, logistic with two cut points, and ordinal logistic with either the full or grouped LMUP score. The recommendations were then tested on the original UK LMUP data.

Results

There were small but no important differences in the findings across the regression models. Logistic regression resulted in the largest loss of information, and assumptions were violated for the linear and ordinal logistic regression. Consequently, robust standard errors were used for linear regression and a partial proportional odds ordinal logistic regression model attempted. The latter could only be fitted for grouped LMUP score.

Conclusion

We recommend the linear regression model with robust standard errors to make full use of the LMUP score when analyzed as an outcome measure. Ordinal logistic regression could be considered, but a partial proportional odds model with grouped LMUP score may be required. Logistic regression is the least-favored option, due to the loss of information. For logistic regression, the cut point for un/planned pregnancy should be between nine and ten. These recommendations will standardize the analysis of LMUP data and enhance comparability of results across studies.

Prevalence and Determinants of Unintended Pregnancy in Mchinji District, Malawi; Using a Conceptual Hierarchy to Inform Analysis

BACKGROUND

In 2012 there were around 85 million unintended pregnancies globally. Unintended pregnancies unnecessarily expose women to the risks associated with pregnancy, unsafe abortion and childbirth, thereby contributing to maternal mortality and morbidity. Studies have identified a range of potential determinants of unplanned pregnancy but have used varying methodologies, measures of pregnancy intention and analysis techniques. Consequently there are many contradictions in their findings. Identifying women at risk of unplanned pregnancy is important as this information can be used to help with designing and targeting interventions and developing preventative policies.

METHODS

4,244 pregnant women from Mchinji District, Malawi were interviewed at home between March and December 2013. They were asked about their pregnancy intention using the validated Chichewa version of the London Measure of Unplanned Pregnancy, as well as their socio-demographics and obstetric and psychiatric history. A conceptual hierarchical model of the determinants of pregnancy intention was developed and used to inform the analysis. Multiple random effects linear regression was used to explore the ways in which factors determine pregnancy intention leading to the identification of women at risk of unplanned pregnancies.

RESULTS

44.4% of pregnancies were planned. On univariate analyses pregnancy intention was associated with mother and father's age and education, marital status, number of live children, birth interval, socio-economic status, intimate partner violence and previous depression all at p<0.001. Multiple linear regression analysis found that increasing socio-economic status is associated with increasing pregnancy intention but its effect is mediated through other factors in the model. Socio-demographic factors of importance were marital status, which was the factor in the model that had the largest effect on pregnancy intention, partner's age and mother's education level. The effect of mother's education level was mediated by maternal reproductive characteristics. Previous depression, abuse in the last year or sexual abuse, younger age, increasing number of children and short birth intervals were all associated with lower pregnancy intention having controlled for all other factors in the model. This suggests that women in Mchinji District who are either young, unmarried women having their first pregnancy, or older, married women who have completed their desired family size or recently given birth, or women who have experienced depression, abuse in the last year or sexual abuse are at higher risk of unintended pregnancies.

CONCLUSION

A simple measure of pregnancy intention with well-established psychometric properties was used to show the distribution of pregnancy planning among women from a poor rural population and to identify those women at higher risk of unintended pregnancy. An analysis informed by a conceptual hierarchical model shed light on the pathways that lead from socio-demographic determinants to pregnancy intention. This information can be used to target family planning services to those most at risk of unplanned pregnancies, particularly women with a history of depression or who are experiencing intimate partner violence.

Evaluation of the psychometric properties of the London Measure of Unplanned Pregnancy in Brazilian Portuguese

BACKGROUND

Estimates of unplanned pregnancy worldwide are of concern, especially in low and middle-income countries, including Brazil. Although the contraceptive prevalence rate is high in Brazil, almost half of all pregnancies are reported as unintended. The only source of nationally representative data about pregnancy intention is the Demographic and Health Survey, as with many other countries. In more recent years, however, it has been realized that concept of unintended pregnancy is potentially more complex and requires more sophisticated measurement strategies, such as the London Measure of Unplanned Pregnancy (LMUP). The LMUP has been translated and validated in other languages, but not Portuguese yet. In this study, we evaluate the psychometric properties of the LMUP in the Portuguese language, Brazilian version.

METHODS

A Brazilian Portuguese version of the LMUP was produced via translation and back-translation. After piloting, the mode of administration was changed from self-completion to interviewer-administration. The measure was field tested with pregnant, postpartum, and postabortion women recruited at maternity and primary health care services in Sao Paulo city. Reliability (internal consistency) was assessed using Cronbach's alpha and item-total correlations. Construct validity was assessed using principal components analysis and hypothesis testing. Scaling was assessed with Mokken analysis.

RESULTS

759 women aged 15-44 completed the Brazilian Portuguese LMUP. There were no missing data. The measure was acceptable and well targeted. Reliability testing demonstrated good internal consistency (alpha = 0.81, all item-rest correlations >0.2). Validity testing confirmed that the measure was unidimensional and that all hypotheses were met: there were lower LMUP median scores among women in the extreme age groups (p < 0.001), among non-married women (p < 0.001) and those with lower educational attainment (p < 0.001). The Loevinger H coefficient was 0.60, indicating a strong scale.

CONCLUSION

The Brazilian Portuguese LMUP is a valid and reliable measure of pregnancy planning/intention that is now available for use in Brazil. It represents a useful addition to the public health research and surveillance toolkit in Brazil.

Why do women invest in pre-pregnancy health and care? A qualitative investigation with women attending maternity services

BACKGROUND

Despite the importance attributed to good pre-pregnancy care and its potential to improve pregnancy and child health outcomes, relatively little is known about why women invest in pre-pregnancy health and care. We sought to gain insight into why women invested in pre-pregnancy health and care.

METHODS

We carried out 20 qualitative in-depth interviews with pregnant or recently pregnant women who were drawn from a survey of antenatal clinic attendees in London, UK. Interviewees were purposively sampled to include high and low investors in pre-pregnancy health and care, with variation in age, partnership status, ethnicity and pre-existing medical conditions. Data analysis was conducted using the Framework method.

RESULTS

We identified three groups in relation to pre-pregnancy health and care: 1) The "prepared" group, who had high levels of pregnancy planning and mostly positive attitudes to micronutrient supplementation outside of pregnancy, carried out pre-pregnancy activities such as taking folic acid and making changes to diet and lifestyle. 2) The "poor knowledge" group, who also had high levels of pregnancy planning, did not carry out pre-pregnancy activities and described themselves as having poor knowledge. Elsewhere in their interviews they expressed a strong dislike of micronutrient supplementation. 3) The "absent pre-pregnancy period" group, had the lowest levels of pregnancy planning and also expressed anti-supplement views. Even discussing the pre-pregnancy period with this group was difficult as responses to questions quickly shifted to focus on pregnancy itself. Knowledge of folic acid was poor in all groups.

CONCLUSION

Different pre-pregnancy care approaches are likely to be needed for each of the groups. Among the "prepared" group, who were proactive and receptive to health messages, greater availability of information and better response from health professionals could improve the range of pre-pregnancy activities carried out. Among the "poor knowledge" group, better response from health professionals might yield greater uptake of pre-pregnancy information. A different, general health strategy might be more appropriate for the "absent pre-pregnancy period" group. The fact that general attitudes to micronutrient supplementation were closely related to whether or not women invested in pre-pregnancy health and care was an unanticipated finding and warrants further investigation.
