Pre-conception health awareness in infertility patients

Barriers and enablers to a healthy lifestyle in people with infertility: a mixed-methods systematic review

BACKGROUND

While there is a recognized role of optimizing lifestyle (diet and physical activity) behaviours in the management of infertility, the best practice remains unknown and factors influencing the lifestyle of people with infertility are not well understood.

OBJECTIVE AND RATIONALE

This systematic review evaluated barriers and enablers to a healthy lifestyle in people with infertility, from the perspectives of people with infertility and health professionals, in order to inform optimal behavioural change strategies.

SEARCH METHODS

Ovid MEDLINE(R), PsycINFO, EMBASE, EBM Reviews, and CINAHL were searched from inception to 28 August 2023. Eligible studies were qualitative and quantitative primary studies that explored barriers and/or enablers to lifestyle for infertility management. Quality assessment was performed using the Centre for Evidence-Based Management Critical Appraisal of a Survey Tool and the Critical Appraisal Skills Programme Qualitative Checklist. Data were analysed by thematic analysis with themes mapped to the Capability, Opportunity, Motivation and Behaviour (COM-B) model and Theoretical Domains Framework (TDF).

OUTCOMES

After screening 12 326 abstracts and 99 full-texts, 27 studies were included (12 quantitative, 6 qualitative and 9 mixed-methods) with 22 studies of women with infertility (n = 2524), 11 studies of men with infertility (n = 1407), and 6 studies of health professionals (n = 372). We identified barriers and enablers relating to capability (e.g. strategies for behaviour change), opportunity (e.g. limited time, resources, and money), and motivation (e.g. interplay between lifestyle and emotional state). Based on the identified themes, suggested intervention components to integrate into lifestyle management of infertility include facilitating development of self-management skills to support lifestyle change (e.g. self-monitoring, action planning, and goal setting) and incorporating mental health strategies (e.g. providing information about the benefits of healthy lifestyle behaviours for mental health and encouraging patients to reframe healthy lifestyle behaviours as self-care strategies).

WIDER IMPLICATIONS

The findings have identified important factors that influence lifestyle management in people with infertility and have suggested relevant intervention components to consider when designing interventions. Given the paucity of qualitative studies identified, more research is needed to further understand the complex and interacting factors that shape lifestyle during the fertility journey.

Cumulative delivery rate per aspiration IVF/ICSI cycle in POSEIDON patients: a real-world evidence study of 9073 patients

STUDY QUESTION

What is the cumulative delivery rate (CDR) per aspiration IVF/ICSI cycle in low-prognosis patients as defined by the Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number (POSEIDON) criteria?

SUMMARY ANSWER

The CDR of POSEIDON patients was on average ∼50% lower than in normal responders and varied across POSEIDON groups; differences were primarily determined by female age, number of embryos obtained, number of embryo transfer (ET) cycles per patient, number of oocytes retrieved, duration of infertility, and BMI.

WHAT IS KNOWN ALREADY

The POSEIDON criteria aim to underline differences related to a poor or suboptimal treatment outcome in terms of oocyte quality and quantity among patients undergoing IVF/ICSI, and thus, create more homogenous groups for the clinical management of infertility and research. POSEIDON patients are presumed to be at a higher risk of failing to achieve a live birth after IVF/ICSI treatment than normal responders with an adequate ovarian reserve. The CDR per initiated/aspiration cycle after the transfer of all fresh and frozen–thawed/warmed embryos has been suggested to be the critical endpoint that sets these groups apart. However, no multicenter study has yet substantiated the validity of the POSEIDON classification in identifying relevant subpopulations of patients with low-prognosis in IVF/ICSI treatment using real-world data.

STUDY DESIGN, SIZE, DURATION

Multicenter population-based retrospective cohort study involving 9073 patients treated in three fertility clinics in Brazil, Turkey and Vietnam between 2015 and 2017.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Participants were women with infertility between 22 and 42 years old in their first IVF/ICSI cycle of standard ovarian stimulation whose fresh and/or frozen embryos were transferred until delivery of a live born or until all embryos were used. Patients were retrospectively classified according to the POSEIDON criteria into four groups based on female age, antral follicle count (AFC), and the number of oocytes retrieved or into a control group of normal responders (non-POSEIDON). POSEIDON patients encompassed younger (<35 years) and older (35 years or above) women with an AFC ≥5 and an unexpected poor (<4 retrieved oocytes) or suboptimal (4–9 retrieved oocytes) response to stimulation, and respective younger and older counterparts with an impaired ovarian reserve (i.e. expected poor responders; AFC <5). Non-POSEIDON patients were those with AFC ≥5 and >9 oocytes retrieved. CDR was computed per one aspirated cycle. Logistic regression analysis was carried out to examine the association between patient classification and CDR.

MAIN RESULTS AND ROLE OF CHANCE

The CDR was lower in the POSEIDON patients than in the non-POSEIDON patients (33.7% vs 50.6%; P < 0.001) and differed across POSEIDON groups (younger unexpected poor responder [Group 1a; n = 212]: 27.8%, younger unexpected suboptimal responder [Group 1b; n = 1785]: 47.8%, older unexpected poor responder [Group 2a; n = 293]: 14.0%, older unexpected suboptimal responder [Group 2b; n = 1275]: 30.5%, younger expected poor responder [Group 3; n = 245]: 29.4%, and older expected poor responder [Group 4; n = 623]: 12.5%. Among unexpected suboptimal/poor responders (POSEIDON Groups 1 and 2), the CDR was twice as high in suboptimal responders (4–9 oocytes retrieved) as in poor responders (<4 oocytes) (P = 0.0004). Logistic regression analysis revealed that the POSEIDON grouping, number of embryos obtained, number of ET cycles per patient, number of oocytes collected, female age, duration of infertility and BMI were relevant predictors for CDR (P < 0.001).

LIMITATIONS, REASONS FOR CAUTION

Our study relied on the antral follicle count as the biomarker used for patient classification. Ovarian stimulation protocols varied across study centers, potentially affecting patient classification.

WIDER IMPLICATIONS OF THE FINDINGS

POSEIDON patients exhibit lower CDR per aspirated IVF/ICSI cycle than normal responders; the differences are mainly determined by female age and number of oocytes retrieved, thereby reflecting the importance of oocyte quality and quantity. Our data substantiate the validity of the POSEIDON criteria in identifying relevant subpopulations of patients with low-prognosis in IVF/ICSI treatment. Efforts in terms of early diagnosis, prevention, and identification of specific interventions that might benefit POSEIDON patients are warranted.

Preconception Care to Reduce the Risks of Overweight and Obesity in Women of Reproductive Age: An Integrative Review

Despite adverse pregnancy outcomes for women with overweight or obesity, preconception guidelines for achieving optimal wellness for women contemplating pregnancy regarding the risks of overweight or obesity are varied based upon national affiliation. The aim of this study was to synthesize the best evidence related to preconception counseling and care focused on overweight or obesity provided to women of reproductive age. An integrative review of original studies was conducted. PubMed, Cumulative Index in Nursing and Allied Health Literature, Ovid, Scopus, Web of Science, and Embase were included. Full-text, data-based articles were searched from 2009 to 2018, with reviews and synthesis completed in 2019 and 2020. Of 8703 initial articles, 31 articles remained in the review. Quality assessment and level of evidence were evaluated based upon criteria from the Joanna Briggs Institute and the Johns Hopkins Nursing Evidence-Based Practice Quality Guide. The level of evidence for the majority of studies was non-experimental but they were of good quality with appropriate methods, samples and relevant results. Limited attention and interest in preconception counseling regarding risks of overweight or obesity by health care professionals were noted, which may contribute to women’s unawareness of these risks on preconception health.

Low Prognosis by the POSEIDON Criteria in Women Undergoing Assisted Reproductive Technology: A Multicenter and Multinational Prevalence Study of Over 13,000 Patients

OBJECTIVE

To estimate the prevalence of low-prognosis patients according to the POSEIDON criteria using real-world data.

DESIGN

Multicenter population-based cohort study.

SETTINGS

Fertility clinics in Brazil, Turkey, and Vietnam.

PATIENTS

Infertile women undergoing assisted reproductive technology using standard ovarian stimulation with exogenous gonadotropins.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Per-period prevalence rates of POSEIDON patients (overall, stratified by POSEIDON groups and by study center) and the effect of covariates on the probability that a patient be classified as "POSEIDON".

RESULTS

A total of 13,146 patients were included. POSEIDON patients represented 43.0% (95% confidence interval [CI] 42.0-43.7) of the studied population, and the prevalence rates varied across study centers (range: 38.6-55.7%). The overall prevalence rates by POSEIDON groups were 44.2% (group 1; 95% CI 42.6-45.9), 36.1% (group 2; 95% CI 34.6-37.7), 5.2% (group 3; 95% CI 4.5-6.0), and 14.4% (group 4; 95% CI: 13.3-15.6). In general, POSEIDON patients were older, had a higher body mass index (BMI), lower ovarian reserve markers, and a higher frequency of female factor as the primary treatment indication than non-POSEIDON patients. The former required larger doses of gonadotropin for ovarian stimulation, despite achieving a 2.5 times lower number of retrieved oocytes than non-POSEIDON patients. Logistic regression analyses revealed that female age, BMI, ovarian reserve, and a female infertility factor were relevant predictors of the POSEIDON condition.

CONCLUSIONS

The estimated prevalence of POSEIDON patients in the general population undergoing ART is significant. These patients differ in clinical characteristics compared with non-POSEIDON patients. The POSEIDON condition is associated with female age, ovarian reserve, BMI, and female infertility. Efforts in terms of diagnosis, counseling, and treatment are needed to reduce the prevalence of low-prognosis patients.

Preconception care for infertile couples: Nurses' and midwives' roles in promoting better maternal and birth outcomes

INTRODUCTION

Preconception care promotes better maternal outcomes, may assist in preventing birth defects and improves fertility awareness among healthy childbearing couples. Yet, the significance of preconception care for infertile couples is undeveloped area of practice in Europe.

AIMS AND OBJECTIVES

To discuss the importance of nurses and midwives in providing preconception care to infertile couples in the United Kingdom and Spain.

DESIGN

Discursive paper.

METHOD

A comparison of different midwifery and nursing approaches to preconception care for infertile couples in two European countries.

FINDINGS

At present, infertile couples' needs for preconception care are not routinely identified or understood. There is an opportunity for these needs to be considered and identified by nurses at the time of investigation for infertility or when planning pregnancy with assisted conception.

CONCLUSIONS

We argue that, by providing preconception care, nurses and midwives have an opportunity to deliver important advice to infertile couples in both primary care and specialist infertility services.

Do subfertile women adjust their habits when trying to conceive?

AIM

The aim of this study was to investigate lifestyle habits and lifestyle adjustments among subfertile women trying to conceive.

MATERIALS AND METHODS

Women (n = 747) were recruited consecutively at their first visit to fertility clinics in mid-Sweden. Participants completed a questionnaire. Data were analyzed using logistic regression, t tests, and chi-square tests.

RESULTS

The response rate was 62% (n = 466). Mean duration of infertility was 1.9 years. During this time 13.2% used tobacco daily, 13.6% drank more than three cups of coffee per day, and 11.6% consumed more than two glasses of alcohol weekly. In this sample, 23.9% of the women were overweight (body mass index, BMI 25-29.9 kg/m(2)), and 12.5% were obese (BMI ≥30 kg/m(2)). Obese women exercised more and changed to healthy diets more frequently than normal-weight women (odds ratio 7.43; 95% confidence interval 3.7-14.9). Six out of ten women (n = 266) took folic acid when they started trying to conceive, but 11% stopped taking folic acid after some time. Taking folic acid was associated with a higher level of education (p < 0.001).

CONCLUSIONS

Among subfertile women, one-third were overweight or obese, and some had other lifestyle factors with known adverse effects on fertility such as use of tobacco. Overweight and obese women adjusted their habits but did not reduce their body mass index. Women of fertile age would benefit from preconception counseling, and the treatment of infertility should routinely offer interventions for lifestyle changes.

Women's views of a fertility awareness and hormonal support approach to subfertility

The aim of this study was to determine the satisfaction among subfertile women of a fertility awareness-based approach, including hormonal therapy to achieve a pregnancy by natural conception. Eighty four women attending a natural fertility service completed a postal questionnaire exploring (1) the acceptability of the sympto-thermal method and (2) the acceptability of using hormone support. Acceptability rates for the fertility charting, clinical service and clinical care were 64.9-91.6%. Acceptability rates were higher in women who did conceive or had experienced past recurrent miscarriages. Taking hormonal luteal support, by any method, was more acceptable for women over 35 years compared to those under 35 years (100% vs. 69.4%, p = 0.014). Vaginal pessaries were the preferred route of administration. The use of a fertility awareness-based method appears to be acceptable amongst subfertile women intending to conceive naturally. Most women using such a method for conception would be open to the use of hormonal support during the fertility cycle or early pregnancy.

Integrating preconceptional care into an IVF programme

AIM

  This paper is a report of a mixed method study of the outcomes of integrating preconceptional care into an in-vitro fertilization programme on nurses' and patients' attitudes and patients' weight and smoking behaviour.

BACKGROUND

  Increasing evidence points to the significant effect of lifestyle factors on in-vitro fertilization outcomes. Optimizing the health of couples before they commence in-vitro fertilization may improve the chance of achieving success.

METHOD

  In 2007, 130 couples attending a university hospital in-vitro fertilization unit and seven nurses were invited to participate in the study. Questionnaires were developed to assess the attitudes of both patients and nurses. Furthermore, the impact of interventions on body mass index and smoking patterns were evaluated.

RESULTS

  All nurses (n = 7) and 101 patients (77·7%) returned completed questionnaires. Analysis revealed a considerable degree of scepticism among the nurses at the outset as to the value of the programme and their ability to perform their new role effectively. Patients valued positively the increased attention to adjusting lifestyle factors with the goal to improve fertility outcomes. Of those participants who smoked or had a body mass index >30, 30% (n = 7/23) of the patients quit smoking and 50% lost weight (n = 15/30), mean loss: 6·1 kg.

CONCLUSION

  Fertility nurses can play a key role in the provision of preconceptional care. Patients with a fertility problem can be motivated to address lifestyle issues before embarking on in-vitro fertilization treatment. The integration of preconceptional care and lifestyle interventions was shown to be feasible in our clinical setting.
