Are migrants during the periconception period less likely to be supplementing with folic acid: An Australian cohort study.

BACKGROUND: Folic acid (FA) supplementation before and in early pregnancy is known to improve outcomes such as reducing neural tube defects; however, little is known about groups in Australia at risk of low FA use. AIM: To determine whether differences exist in FA supplementation rates between Australian-born women and migrant women, with a secondary aim of examining the sociodemographic characteristics of women who are not supplementing with FA in early pregnancy. METHODS: A retrospective cohort study from January 2018-July 2022 in a high-migrant population in Western Sydney, Australia. Multivariate logistic regression analysis was conducted adjusting for confounders including place of birth, age, ethnicity, parity, history of diabetes, and type of conception. FINDINGS: There were 48,045 women who met inclusion criteria; 65% of whom were migrants. We identified that 39.4% of the study population did not report FA supplementation by early pregnancy. Women who were migrants were more likely to report FA usage than those born in Australia (aOR 1.24; 95%CI 1.17-1.31). Women least likely to report use of FA were women < 20 years of age (aOR 0.54; 95%CI 0.44-0.67) and multiparous women (aOR 0.84; 95%CI 0.82-0.86). Women with type 1 or type 2 diabetes were more likely to report FA use (aOR 1.66; 95%CI 1.11-2.48, aOR 1.30; 95%CI 1.05-1.61). CONCLUSION: A significant proportion of the population did not report FA supplementation before or during early pregnancy. To increase uptake of FA supplementation, clinicians and public health messaging should target at-risk groups.

Preconception and Pregnancy Nutrition Support for Women with a History of Bariatric Surgery: A Mixed-Methods Survey of Healthcare Professionals in the UK.

Preconception bariatric surgery improves obesity-related maternal pregnancy complications but may reduce the absorption of nutrients required for healthy fetal growth and development. Women who receive preconception nutritional support after bariatric surgery are less likely to have adverse pregnancy outcomes. This study aimed to investigate the provision of preconception and pregnancy-specific nutritional support for women having bariatric surgery in the UK. A mixed-methods survey was distributed to healthcare professionals working in obesity or maternity services between December 2018 and October 2019. We collected both quantitative and qualitative data which were analysed using a mixed-methods approach. We received 135 responses from online (n = 99) and postal (n = 36) questionnaires. Only 45% of participants reported being 'very familiar' with the preconception/pregnancy nutritional needs of this population. Barriers to providing nutritional support included: a lack of resources and time; poor communication both across services and with women; not having contact with women preconception; and a lack of information and guidance. Respondents felt that dietitians have the expertise in nutrition necessary to provide support; however, GPs and midwives have the most frequent patient access post-surgery, both before and during pregnancy. Optimal preconception and pregnancy-related nutritional support requires multidisciplinary care pre- and post-surgery, and healthcare professionals require training and guidance to inform practice.

Current preconception care practice in the Netherlands - An evaluation study among birth care professionals.

OBJECTIVE: To evaluate the current practice of preconception care in the Netherlands and the perceptions of birth care professionals concerning preconception care. METHODS: We have developed a digital questionnaire and conducted a cross-sectional study by distributing the questionnaire among 102 organisations: 90 primary care midwifery practices and obstetric departments of 12 hospitals in the Southwest region of the Netherlands between December 2020 and March 2021. One birth care professional per organization was asked to complete the questionnaire. Descriptive statistics were used to present the results. FINDINGS: Respondents of eighty-three organisations (81.4 %) filled in the questionnaire, of whom 74 respondents were independent primary care midwives and 9 respondents were obstetricians. Preconception care mostly consisted of an individual consultation in which personalized health and lifestyle advice was given. Among the respondents, 44.4 % reported that the organization had a preconception care protocol. The way in which the consultation was carried out, as well as the health and lifestyle related questions asked, differed between respondents. More than 85 % of the respondents inquire about the following possible risk factors for complications: maternal illnesses, obstetric history, folic acid supplement intake, alcohol intake, smoking, substance abuse, hereditary disease, prescription medication, dietary habits, overweight, and birth defects in the family. The respondents acknowledged that preconception care should be offered to all couples who wish to become pregnant, as opposed to offering preconception care only to those with an increased risk of complications. Still, respondents do not receive many questions regarding the preconception period or requests for preconception care consultations. KEY CONCLUSION: Birth care professionals acknowledge the need for preconception care for all couples. In the Netherlands, preconception care consists mostly of an individual consultation with recommendations for health and lifestyle advice. However, the identification of risk factors varies between birth care professionals and less than half of the respondents indicate that they have a protocol available in their practice. Furthermore, the demand of parents-to-be for preconception care is low. More research, that includes more obstetricians, is necessary to investigate if there is a difference between the care provided by primary care midwives and obstetricians. IMPLICATIONS FOR PRACTICE: To increase the awareness and uptake of preconception care, it would be prudent to emphasize its importance to parents-to-be and professionals, and actively promote the use of widespread, standardized protocols for birth care professionals.

Preconception Counseling and Care.

Primary care for women and other patients with similar reproductive potential can include a discussion about pregnancy and, depending on the patient's intent, contraceptive care or preconception care. Folic acid supplementation of at least 400 mcg per day is recommended to reduce the risk of neural tube defects, because many pregnancies are unplanned. Having a body mass index of 18.5 to 24.9 kg per m2 before pregnancy also reduces complications. Patients with a history of bariatric surgery should delay pregnancy for at least 12 months post-procedure and ensure that their nutritional status is adequate before conception. It is essential to review the patient's medications and chronic medical conditions to avoid teratogens and optimize treatment before conception to reduce maternal and fetal morbidity and mortality. Having a prepregnancy A1C level of less than 6.5% is strongly recommended for patients with diabetes mellitus to minimize congenital anomalies and complications. Vaccinations should be updated to prevent adverse outcomes related to infections. Infectious disease screenings should be updated before conception to allow for treatment, prophylaxis, or timing of pregnancy to avoid complications. Screening and counseling should be provided for substance use and potential environmental exposures to identify and mitigate detrimental exposures before pregnancy.

The effect of a locally tailored intervention on the uptake of preconception care in the Netherlands: a stepped-wedge cluster randomized trial (APROPOS-II study).

BACKGROUND: The preconception period provides a window of opportunity for interventions aiming to reduce unhealthy lifestyle behaviours and their negative effect on pregnancy outcomes. This study aimed to assess the effectiveness of a locally tailored preconception care (PCC) intervention in a hybrid-II effectiveness implementation design. METHODS: A stepped-wedge cluster randomized controlled trial was performed in four Dutch municipalities. The intervention contained a social marketing strategy aiming to improve the uptake (prospective parents) and the provision (healthcare providers) of PCC. Prospective parents participated by administering a questionnaire in early pregnancy recalling their preconceptional behaviours. Experiences of healthcare providers were also evaluated through questionnaires. The composite primary outcome was adherence to at least three out of four preconceptional lifestyle recommendations (early initiation of folic acid supplements, healthy nutrition, no smoking or alcohol use). Secondary outcomes were preconceptional lifestyle behaviour change, (online) reach of the intervention and improved knowledge among healthcare providers. RESULTS: A total of 850 women and 154 men participated in the control phase and 213 women and 39 men in the intervention phase. The composite primary outcome significantly improved among women participating in the municipality where the reach of the intervention was highest (Relative Risk (RR) 1.57 (95% Confidence Interval (CI) 1.11-2.22). Among women, vegetable intake had significantly improved in the intervention phase (RR 1.82 (95%CI 1.14-2.91)). The aimed online reach- and engagement rate of the intervention was achieved most of the time. Also, after the intervention, more healthcare providers were aware of PCC-risk factors (54.5% vs. 47.7%; p = 0.040) and more healthcare providers considered it easier to start a conversation about PCC (75.0% vs. 47.9%; p = 0.030). CONCLUSION: The intervention showed some tentative positive effects on lifestyle behaviours among prospective parents. Primarily on vegetable intake and the knowledge and competence of healthcare providers. The results of this study contribute to the evidence regarding successfully implementing PCC-interventions to optimize the health of prospective parents and future generations.

Preconception health behaviours of women planning a Pregnancy: A scale development study.

OBJECTIVES: This study aims to develop a health behaviour scale for the preconception period and assess the preconception health behaviours of women who have applied to the municipality for marriage and are planning a pregnancy within a year. METHOD: This is a methodological and descriptive study. While the exploratory and confirmatory factor analysis, the test-retest method and Cronbach's alpha internal consistency methods were used for data analysis in the methodological stage. The Mann-Whitney U test and Kruskal-Wallis test were used in the descriptive stage. Statistical significance was accepted as p < 0.05. In total, 260 women were enrolled in the study during the scale development stage. Upon completion of the scale development stage, for the evaluation of preconception health behaviours was conducted with 331 women who were planning pregnancy within one year. RESULTS: The Preconception Health Behaviours Scale consists of 18 items and 4 subscales. The Cronbach's alpha value was 0.867. The subscales "Preparation", "Coping Skills", "High-Risk Behaviours" and "Nutrition and Sleep" were found to be reliable. The mean score obtained from the scale was 29.50 ± 6.57. It was determined that level of education and level of knowledge on preconception care affected the preconception health behaviours of the women who have applied for marriage. CONCLUSION: The Preconception Health Behaviours Scale is valid and highly reliable. Furthermore, a high level of education and high knowledge on preconception care affect preconception health behaviours positively.

A comprehensive assessment of preconception health needs and interventions regarding women of childbearing age: a systematic review.

Background: This systematic review summarizes the preconception health needs of women in childbearing age, necessary to be addressed to have an eventual safe and healthy pregnancy. Methods: Web of Science, PubMed and Scopus were searched. We excluded studies involving women with reproductive system pathologies and referring to interconceptive or pregnancy period and non-empirical or only abstract studies. Two researchers independently performed the blind screening based on titles/abstracts and full-text and the quality assessment. Results: Four major domains resulted from the thematic analysis: knowledge, behaviors and attitudes, health status and access to healthcare services. The most examined topics were knowledge and awareness on preconception health, folic acid assumption, tobacco and alcohol consumption, physical activity and healthy diet. Conclusions: This review could assist healthcare professionals (physicians, nurses, midwives) in guiding tailored counselling to women to provide the adequate level of preconception care and act as a reference to policymakers.

[The role of health resort factors in preconception preparation of patients with reproductive disorders]. / Rol' sanatorno-kurortnykh faktorov v pregravidarnoi podgotovke patsientok s narusheniyami reproduktivnoi funktsii.

Reproductive dysfunction is a multifactorial problem, for the correction of which the most difficult are cases of pathology comorbidity. Individual preconception preparation, taking into account risk factors, is recognized as an effective measure to increase the chances of conception and prevent reproductive losses. OBJECTIVE: Optimization of treatment and rehabilitation measures at the preconception stage in patients with reproductive disorders. MATERIAL AND METHODS: The effectiveness of the use of natural and preformed physical factors in the preconception preparation of 180 women who underwent medical and rehabilitation measures in the health resort of the Altai Territory - the resort town of Belokurikha (Group 1, 79 patients) and outpatient conditions in the city of Barnaul (Group 2, 101 patients). Comprehensive spa treatment included climatotherapy, a combination of various methods: balneotherapy, peloidtherapy, physiotherapy and a prolonged course of herbal medicine. RESULTS: In patients of the 1st group, who underwent a course of rehabilitation treatment in a sanatorium-resort environment, compared with patients of the 2nd group, early reproductive losses were less common during pregnancy (7.1% and 20.7%, respectively; p=0.04) and more frequent term deliveries occurred (92.8% and 77.2%, respectively; p=0.02). The most significant predictors of the ineffectiveness of preconception preparation were the presence in patients of: chronic cystitis and autoimmune thyroiditis with hypothyroidism; oligomenorrhea at the time of pregnancy planning; aggravated by early reproductive losses and long-term wearing of intrauterine contraception history; burdened heredity for violation of carbohydrate metabolism. CONCLUSION: Comprehensive preconception preparation in the sanatorium-resort conditions of Belokurikha helps to increase the fertility of patients with reproductive disorders, the trophostimulating effect in the genital organs and the restoration of endometrial reception, which makes it possible to recommend this method for use in clinical practice.

Pregnancy planning health information and service needs of women with chronic non-communicable conditions: a systematic review and narrative synthesis.

BACKGROUND: Preparing for pregnancy and being in the best possible health before conception improves reproductive outcomes. For women living with a chronic non-communicable disease (NCD), pregnancy planning is essential to allow optimal disease control in preparation for pregnancy. AIM: The aim was to review the literature relating to the pregnancy planning health information and service needs of women with NCDs. METHOD: The MEDLINE (Ovid), Embase (Ovid), Emcare (Ovid), PsycINFO (Ovid), CINAHL and Scopus databases were searched. Studies were included if they were published in peer-reviewed English language journals between January 2010 and June 2020 and reported on the pregnancy planning health information and service needs of women with rheumatic diseases, asthma, cystic fibrosis, depression and/or anxiety, type 1 diabetes mellitus, epilepsy, or multiple sclerosis. Risk of bias was assessed using QualSyst. The characteristics of the studies were tabulated and summarised. Key findings of the included studies were analysed thematically using an inductive approach, where the study findings determined the themes. Findings are reported in a narrative synthesis. RESULTS: The database searches yielded 8291 results, of which 4304 remained after duplicates were removed. After abstract screening 104 full-text papers were reviewed. Of these 15 met inclusion criteria and were included in analysis. The narrative synthesis of the included studies revealed six themes: 'Women with chronic conditions have unmet preconception health information needs', 'Women with chronic conditions want personalised preconception health information', 'Preferred sources of preconception health information', 'Learning from the experiences of other women', 'Improving preconception health discussions with health care professionals', and 'Women want holistic care'. These themes were consistent across all studies, highlighting the similarity of experiences and needs of women with different chronic conditions. CONCLUSION: To improve pregnancy outcomes for women living with NCDs, health care providers need to ask women of reproductive age proactively and routinely about their pregnancy intentions and provide them with personalised advice on how to avoid unplanned pregnancy and be in optimal health when they wish to conceive.

Association between pregnancy intention and preconception health behaviors.

BACKGROUND: Female adolescent and young adult (AYA) cancer survivors face higher infertility and pregnancy risks than peers with no cancer history. Preconception health behaviors such as physical activity (PA), tobacco smoking, and alcohol intake influence reproductive outcomes. In general populations, pregnancy intention is positively associated with healthy preconception behaviors, but it has not been studied among AYA survivors. The authors hypothesized that higher pregnancy intention would be associated with healthier behaviors, especially among AYA survivors with perceived infertility risk. METHODS: A cross-sectional analysis was conducted with data collected between 2013 and 2017 from 1071 female AYA survivors aged 18 to 39 years who had completed their primary cancer treatment and enrolled in an ovarian function study. Self-reported intention dimensions were measured as a pregnancy intention score (PIS) and trying now to become pregnant. Multivariable linear (PA), binary (smoking), and ordinal (alcohol use) logistic regressions were used to estimate associations between intentions and preconception behaviors, with adjustments made for demographic and cancer characteristics. Effect modification by perceived infertility risk was assessed. RESULTS: The mean PIS was 1.1 (SD, 0.77) on a 0 to 2 scale (2 = high intention), and 8.9% were attempting pregnancy now. A higher PIS was associated with increased PA (ß, 0.08; 95% CI, 0.11-1.04), whereas ambivalence in pregnancy intention was associated with lower alcohol consumption (odds ratio, 0.72; 95% CI, 0.55-0.95). Pregnancy intentions were not associated with smoking. Perceived infertility risk strengthened the relationship between PIS and PA (P < .05). CONCLUSIONS: Pregnancy intentions were associated with some healthier preconception behaviors in AYA survivors. Medical professionals caring for AYA survivors may consider pregnancy intention screening to guide conversations on preconception health.

Time to conceive after myomectomy: should we advise a minimum time interval? A systematic review.

The optimal time interval between myomectomy and pregnancy is unclear and no specific guidelines exist. The aim of this review was to study the time interval from myomectomy to pregnancy and the occurrence of uterine rupture after myomectomy. Randomized controlled trials, cohort studies and retrospective studies were used to assess the primary objective, and case reports, cases series or letters to the editor for the secondary objective. Only articles reporting myomectomy performed via the vaginal route, laparotomy, laparoscopy or robot-assisted surgery were selected for inclusion. Among 3852 women who wanted to become pregnant after the surgery, 2889 became pregnant, accounting for 3000 pregnancies (77.9%) and 2097 live births (54.4%). Mean time between myomectomy and pregnancy was estimated at 17.6 months (SD 9.2) for 2451 pregnant women. Among 1016 women, a third were advised to delay attempting to conceive for between 3 and 6 months and another third for between 6 and 12 months. A total of 70 spontaneous uterine ruptures with a mean gestational age of 31 weeks at occurrence were identified. No linear relationship was found between gestational age at the event and time interval from myomectomy to conception (P = 0.706). There are insufficient data to advise a minimal time interval between myomectomy and conception.

Improvements in PCOS characteristics and phenotype severity during a randomized controlled lifestyle intervention.

RESEARCH QUESTION: What is the effect of weight loss through different interventions (three-component lifestyle intervention with short message service [SMS+] versus three-component lifestyle intervention without SMS [SMS-] versus care as usual [CAU]) on polycystic ovary syndrome (PCOS) characteristics (ovulatory dysfunction, hyperandrogenism, polycystic ovarian morphology [PCOM]) and phenotype distribution? DESIGN: Analysis of secondary outcome measures of a randomized controlled trial. Women diagnosed with PCOS (n = 183), who wished to become pregnant, with a body mass index above 25 kg/m², were assigned to a 1-year three-component (cognitive behavioural therapy, diet, exercise) lifestyle intervention group, with or without SMS, or to CAU (advice to lose weight). RESULTS: The prevalence of biochemical hyperandrogenism was 30.9% less in the SMS- group compared with CAU after 1 year (P = 0.027). Within-group analyses revealed significant improvements in ovulatory dysfunction (SMS+: -39.8%, P = 0.001; SMS-: -30.5%, P = 0.001; CAU: -32.1%, P < 0.001), biochemical hyperandrogenism (SMS-: -27.8%, P = 0.007) and PCOM (SMS-: -14.0%, P = 0.034). Weight loss had a significantly favourable effect on the chance of having ovulatory dysfunction (estimate 0.157 SE 0.030, P < 0.001) and hyperandrogenism (estimate 0.097 SE 0.027, P < 0.001). CONCLUSIONS: All groups demonstrated improvements in PCOS characteristics, although these were more profound within the lifestyle intervention groups. Weight loss per se led to an amelioration of diagnostic characteristics and in the phenotype of PCOS. A three-component lifestyle intervention aimed at a 5-10% weight loss should be recommended for all women with PCOS before they become pregnant.

Periconceptional Folate Supplementation in Women after Bariatric Surgery-A Narrative Review.

The prevalence of obesity is increasing globally, and along with it, there is a growing number of patients opting to undergo bariatric surgery to treat this condition. Whilst it has many advantages, bariatric surgery is known to induce micronutrient deficiency, with possible deleterious effects on overall health. This topic becomes even more relevant during pregnancy, where deficiencies can also affect the developing fetus, possibly being the cause of an increase in congenital anomalies. Most notably amongst these micronutrients is folate, or vitamin B9, which plays an essential role in development, gene expression and genomic stability. As insufficient levels of folate are associated with neural tube defects in the fetus, preventing and treating folate deficiencies during pregnancies after bariatric surgery is a relevant issue. Unfortunately, folate supplementation recommendations for bariatric patients who wish to become pregnant are not clear. In this narrative review, we discuss whether the recommendations for the general population are still valid for bariatric patients. Furthermore, we discuss the role of folate in the human body, folate status in both non-bariatric and bariatric patients, the various types of folate that are available for substitution and the risk associated with over-supplementation.

Determinants of practice of preconception care among women of reproductive age group in southern Ethiopia, 2020: content analysis.

BACKGROUND: Preconception care (PCC) is a series of biomedical, mental, and psycho-social health services provided to women and a couple before pregnancy and throughout subsequent pregnancies for desired outcomes. Millions of women and new-borns have died in low-income countries due to impediments that arise before and exaggerate during pregnancies that are not deal with as part of pre-conception care. To the best of our knowledge, however, there is a lack of information about preconception care practice and its determinants in southern Ethiopia, including the study area. This study was therefore planned to assess the practice of preconception care and its determinants among mothers who recently gave birth in Wolkite town, southern Ethiopia, in 2020. METHODS: A community-based cross-sectional study was conducted from February 1 to 30, 2020. A total of 600 mothers who have given birth in the last 12 months have been randomly selected. A two-stage sampling technique was employed. For data collection, a pre-tested, semi-structured questionnaire was used. The data was encoded and entered into Epi-Data version 3.1 and exported for analysis to SPSS version 23. Household wealth status was determined through the application of principal component analysis(PCA). The practice PCC was considered as a count variable and measured as a minimum score of 0 and a maximum of 10. A bivariable statistical analysis was performed through analysis of variance (ANOVA) and independent t-tests and variables with a p-value of < 0.05 were eligible for the generalized linear regression model. To see the weight of each explanatory variable on PCC utilization, generalized linear regression with a Poisson link was done. RESULTS: Of the sampled 600 participants, 591 took part in the study, which yielded a response rate of 98.8%.The mean (± SD) score of the practice of PCC was 3.94 (± 1.98) with minimum and maximum scores of 0 and 10 respectively. Only 6.4% (95%CI: 4.6, 8.6) of mothers received all selected items of PCC services. Thecommonest item received by 67.2% of mothers was Folic acid supplementation, while 16.1% of mothers received the least item of optimizing psychological health. Education status of mother[AOR 0.74, 95%CI 0.63, 0.97], time spent to access nearby health facilities [AOR 0.69, 95%CI 0.58, 0.83], availability of PCC unit [AOR 1.46; 95%CI 1.17, 1.67], mother's knowledge on PCC [AOR 1.34, 95%CI 1.13, 1.65], being a model household [AOR 1.31, 95%CI 1.18, 1.52] and women's autonomy in decision making [AOR 0.75, 95%CI 0.64, 0.96] were identified as significant predictors of practice of PCC. CONCLUSION: The uptake of WHO-recommended PCC service elements in the current study area was found to be unsatisfactory. Stakeholders must therefore increase their efforts to align PCC units with existing MNCH service delivery points, improve women's decision-making autonomy, and focus on behavioral change communication to strengthen PCC practice. Plain language summary Preconception care (PCC) is a series of biomedical, mental, and psycho-social health services provided to women and a couple before pregnancy and throughout subsequent pregnancies for better endings. The main goal of the PCC is to improve maternal and child health outcomes, by-promoting wellness and providing preventive care. It can also be seen as an earlier chance for teenage girls, mothers, and children to live a better and longer-term healthy life. Pieces of PCC service packages suggested by the World Health Organization(WHO) are, micronutrient supplementation (Folate supplementation), infectious disease (STI/HIV) screening and testing, chronic disease screening and management, healthy diet therapy, vaccination, prevention of substance use (cessation of cigarette smoking and too much alcohol consumption), optimizing psychological health, counseling on the importance of exercise and reproductive health planning and implementation. Millions of women and new-borns have died in low-income countries due to impediments that arise before and exaggerate during pregnancies that are not deal with as part of pre-conception care. To the best of our knowledge, however, there is a lack of information about preconception care practice and its determinants in southern Ethiopia, including the study area. This study was therefore planned to evaluate the practice of preconception care and its determinants among mothers who recently gave birth in Wolkite town, southern Ethiopia, in 2020. Mothers who have given birth in the last 12 months have been randomly selected Household wealth status was determined through the application of principal component analysis(PCA). To see the weight of each explanatory variable on PCC, generalized linear regression with a Poisson type was done. Accordingly, the Education status of the mother, time spent to access nearby health facilities, availability of PCC unit, mother's knowledge on PCC, being a model household, and women's autonomy in decision making were identified as significant predictors of practice of PCC. Stakeholders must therefore increase their efforts to align PCC units with existing MNCH service delivery points, improve women's decision-making autonomy, and focus on behavioral change communication to strengthen PCC practice.

Preconception lifestyle advice for people with infertility.

BACKGROUND: Infertility is a prevalent problem that has significant consequences for individuals, families, and the community. Modifiable lifestyle factors may affect the chance of people with infertility having a baby. However, no guideline is available about what preconception advice should be offered. It is important to determine what preconception advice should be given to people with infertility and to evaluate whether this advice helps them make positive behavioural changes to improve their lifestyle and their chances of conceiving. OBJECTIVES: To assess the safety and effectiveness of preconception lifestyle advice on fertility outcomes and lifestyle behavioural changes for people with infertility. SEARCH METHODS: We searched the Cochrane Gynaecology and Fertility Group Specialised Register of controlled trials, CENTRAL, MEDLINE, Embase, PsycINFO, AMED, CINAHL, trial registers, Google Scholar, and Epistemonikos in January 2021; we checked references and contacted field experts to identify additional studies. SELECTION CRITERIA: We included randomised controlled trials (RCTs), randomised cross-over studies, and cluster-randomised studies that compared at least one form of preconception lifestyle advice with routine care or attention control for people with infertility. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures recommended by Cochrane. Primary effectiveness outcomes were live birth and ongoing pregnancy. Primary safety outcomes were adverse events and miscarriage. Secondary outcomes included reported behavioural changes in lifestyle, birth weight, gestational age, clinical pregnancy, time to pregnancy, quality of life, and male factor infertility outcomes. We assessed the overall quality of evidence using GRADE criteria. MAIN RESULTS: We included in the review seven RCTs involving 2130 participants. Only one RCT included male partners. Three studies compared preconception lifestyle advice on a combination of topics with routine care or attention control. Four studies compared preconception lifestyle advice on one topic (weight, alcohol intake, or smoking) with routine care for women with infertility and specific lifestyle characteristics. The evidence was of low to very low-quality. The main limitations of the included studies were serious risk of bias due to lack of blinding, serious imprecision, and poor reporting of outcome measures. Preconception lifestyle advice on a combination of topics versus routine care or attention control Preconception lifestyle advice on a combination of topics may result in little to no difference in the number of live births (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.79 to 1.10; 1 RCT, 626 participants), but the quality of evidence was low. No studies reported on adverse events or miscarriage. Due to very low-quality evidence, we are uncertain whether preconception lifestyle advice on a combination of topics affects lifestyle behavioural changes: body mass index (BMI) (mean difference (MD) -1.06 kg/m², 95% CI -2.33 to 0.21; 1 RCT, 180 participants), vegetable intake (MD 12.50 grams/d, 95% CI -8.43 to 33.43; 1 RCT, 264 participants), alcohol abstinence in men (RR 1.08, 95% CI 0.74 to 1.58; 1 RCT, 210 participants), or smoking cessation in men (RR 1.01, 95% CI 0.91 to 1.12; 1 RCT, 212 participants). Preconception lifestyle advice on a combination of topics may result in little to no difference in the number of women with adequate folic acid supplement use (RR 0.98, 95% CI 0.95 to 1.01; 2 RCTs, 850 participants; I² = 4%), alcohol abstinence (RR 1.07, 95% CI 0.99 to 1.17; 1 RCT, 607 participants), and smoking cessation (RR 1.01, 95% CI 0.98 to 1.04; 1 RCT, 606 participants), on low quality evidence. No studies reported on other behavioural changes. Preconception lifestyle advice on weight versus routine care Studies on preconception lifestyle advice on weight were identified only in women with infertility and obesity. Compared to routine care, we are uncertain whether preconception lifestyle advice on weight affects the number of live births (RR 0.94, 95% CI 0.62 to 1.43; 2 RCTs, 707 participants; I² = 68%; very low-quality evidence), adverse events including gestational diabetes (RR 0.78, 95% CI 0.48 to 1.26; 1 RCT, 317 participants; very low-quality evidence), hypertension (RR 1.07, 95% CI 0.66 to 1.75; 1 RCT, 317 participants; very low-quality evidence), or miscarriage (RR 1.50, 95% CI 0.95 to 2.37; 1 RCT, 577 participants; very low-quality evidence). Regarding lifestyle behavioural changes for women with infertility and obesity, preconception lifestyle advice on weight may slightly reduce BMI (MD -1.30 kg/m², 95% CI -1.58 to -1.02; 1 RCT, 574 participants; low-quality evidence). Due to very low-quality evidence, we are uncertain whether preconception lifestyle advice affects the percentage of weight loss, vegetable and fruit intake, alcohol abstinence, or physical activity. No studies reported on other behavioural changes. Preconception lifestyle advice on alcohol intake versus routine care Studies on preconception lifestyle advice on alcohol intake were identified only in at-risk drinking women with infertility. We are uncertain whether preconception lifestyle advice on alcohol intake affects the number of live births (RR 1.15, 95% CI 0.53 to 2.50; 1 RCT, 37 participants; very low-quality evidence) or miscarriages (RR 1.31, 95% CI 0.21 to 8.34; 1 RCT, 37 participants; very low-quality evidence). One study reported on behavioural changes for alcohol consumption but not as defined in the review methods. No studies reported on adverse events or other behavioural changes. Preconception lifestyle advice on smoking versus routine care Studies on preconception lifestyle advice on smoking were identified only in smoking women with infertility. No studies reported on live birth, ongoing pregnancy, adverse events, or miscarriage. One study reported on behavioural changes for smoking but not as defined in the review methods. AUTHORS' CONCLUSIONS: Low-quality evidence suggests that preconception lifestyle advice on a combination of topics may result in little to no difference in the number of live births. Evidence was insufficient to allow conclusions on the effects of preconception lifestyle advice on adverse events and miscarriage and on safety, as no studies were found that looked at these outcomes, or the studies were of very low quality. This review does not provide clear guidance for clinical practice in this area. However, it does highlight the need for high-quality RCTs to investigate preconception lifestyle advice on a combination of topics and to assess relevant effectiveness and safety outcomes in men and women with infertility.

Association of maternal body mass index with intellectual disability risk.

OBJECTIVES: The study aimed to investigate the association between maternal body mass index (BMI) in early pregnancy and children's intellectual disability (ID) risk in the absence of chromosomal disorders, neurofibromatosis and tuberous sclerosis, taking adverse birth outcomes, maternal hypertension/diabetes and maternal socioeconomic status into consideration. METHODS: We conducted a cohort study of singletons without common genetic defects born in Sweden during 1992-2006, and followed them from birth until 31 December 2014 (n=1 186 836). Cox proportional hazards models were used to analyse the association between maternal BMI in early pregnancy and the risk of offspring's ID. RESULTS: The risk of ID was higher in children born to mothers who were underweight (HR=1.21, 95% CI=1.07 to 1.36), overweight (HR=1.28, 95% CI=1.21 to 1.34) or had obesity class I (HR=1.63, 95% CI=1.53 to 1.74), obesity class II (HR=2.08, 95% CI=1.88 to 2.30) and obesity class III (HR=2.31, 95% CI=1.46 to 3.65) than in children born to normal weight mothers. Results remained consistent after excluding children with adverse birth outcome or born to mothers with gestational hypertension/diabetes. Analysis stratified by maternal education and annual household income showed that the association between maternal underweight and children's ID risk was attenuated among children of mothers with tertiary education or with high income. CONCLUSIONS: Our findings suggest that maternal underweight or overweight/obesity in early pregnancy was associated with the development of ID in their offspring. This association was independent of the effect of adverse birth outcomes and maternal hypertension/diabetes. High socioeconomic status may attenuate the risk of ID among children of underweight mothers. This study highlights the importance of improving health education before conception to reduce children's ID risk.

Surgical management of endometriotic women with pregnancy intention in France: A national snapshot of centers performing a high volume of endometriosis procedures.

OBJECTIVE: To provide a snapshot of the surgical management of endometriosis in French high-volume activity centers. METHODS: Analysis of prospectively collected data between November 2015 and May 2017 in 21 centers with a high volume of endometriosis surgery in France. Each facility could include up to 40 patients undergoing laparoscopy for endometriosis. Data were collected before and two months after surgery. RESULTS: 361 patients were enrolled in the study. Twenty-seven patients (7.48%) were lost to follow-up at the month 2 visit. Endometriosis stage was I-II in 33.70% of patients and III-IV in 66.30%. Uterosacral ligament resection was the most frequently performed procedure (50.97%) followed by rectal surgery (31.58%), ovarian procedures for endometrioma, procedures for ureters (21.33%) and the bladder (11.91%). Antiadhesion agents were employed in 215/361 (59.56%) patients. The median length of hospital stay after surgery was 2 (IQR 1 - 4) days. Post-operative complications were recorded in 9.34% of patients. Rectovaginal fistulae occurred in 8 patients (2.41%), pelvic abscess in 4 (1.20%) and bladder atony in 3 (0.90%). 17 patients (5.14%) required a second surgical procedure after a median time of 31 days (IQR 9 - 81). Two months after surgery, 95.09% of patients reported being satisfied or very satisfied with the surgery. CONCLUSION: Our study shows that surgical management of endometriosis in centers with a high volume of endometriosis surgery, mainly concerns women presenting with severe disease and deep localizations, with an overall risk of major complications inferior to 10% and a high rate of patient satisfaction.

Factors Associated with Inflammatory Bowel Disease Flare During Pregnancy Among Women with Preconception Remission.

BACKGROUND: The factors associated with inflammatory bowel diseases (IBD) relapse throughout gestation in those with preconception remission remain unknown. AIMS: We aimed to investigate disease and pregnancy course among IBD women with quiescent disease at conception. METHODS: Women with IBD attending a multidisciplinary clinic for preconception, antenatal and postnatal treatment were prospectively recruited during 2011-2018. RESULTS: Overall, 298 women with IBD with quiescent disease at the time of conception constituted the study cohort. Of these, 112 (37.6%) women experienced disease flare during pregnancy. The risk of disease relapse was higher in those with ulcerative colitis (UC) as compared to those with Crohn's disease (CD) (48.1% vs. 31.8%, P = 0.005). The proportion of women with prior IBD-related gastrointestinal surgery was lower in those who experienced disease flare up (13.4% vs. 26.3%, P = 0.009). The use of biologic therapy at the time of conception was associated with lower rates of disease relapse (25.0% vs. 43.9%, P = 0.001). In multivariate analysis, use of conventional medications or no treatment (aOR [95% CI]: 2.0 (1.12, 3.57), P = 0.02) and lack of prior history of IBD-related surgery (aOR [95% CI]: 3.13 (1.37, 7.14), P = 0.007) were independently positively associated with disease relapse. Rates of hospitalization during pregnancy (21.4% vs. 2.2%, P < 0.001) and preterm delivery (22.3% vs. 9.1%, P = 0.002) were higher, and birthweight was lower (median 2987 vs. 3153 grams, P = 0.05) in those with disease flare as compared to those who maintained remission. CONCLUSION: Prior IBD-related surgery and biologic therapy were found as independent protective factors against relapse during pregnancy among women with quiescent disease at conception.

Identifying Patient Priorities for Preconception and Pregnancy Counseling in IBD.

BACKGROUND: Inflammatory bowel disease (IBD) commonly affects women of reproductive age. Many patients lacking knowledge about IBD and reproduction make uninformed decisions, such as voluntary childlessness and medication cessation. Education should be individualized to the patient's knowledge base and include topics of most importance to the patient. Our study aimed to describe the priority rankings of topics selected by patients seeking preconception and pregnancy counseling. METHODS: As part of an ongoing prospective study, patients with IBD were asked to rank, in order of importance, nine a priori preconception, pregnancy, and postpartum topics they would like addressed by our specialized care team, which includes an IBD physician and a high-risk obstetrician. χ2 and Fisher's exact tests were used to assess associations between clinical and demographic characteristics and priority rankings, and a p value cutoff for significance was set as .05. RESULTS: One hundred and fifty-eight women with IBD (mean (IQR) age; 32 (28-37) years) were seen in consultation, and 116 (70 (60%) CD, 43 (37%) UC, and 3 (3%) IBD-U) completed intake forms were analyzed. There were 78 (68%) women seen in the preconception stage, median age 31 (IQR 28-34), and 38 women (32%) were pregnant, median age 32 (IQR 28-33). Safety of IBD medications during pregnancy was most commonly ranked as top priority (40%) for all patients regardless of pregnancy status, followed by control of IBD disease activity and impact on pregnancy (31%), impact of IBD and surgery on fertility (19%), pregnancy outcomes for the baby (18%), mode of delivery (6%), inheritance of IBD (4%), breastfeeding (2%), nutritional health (2%), and vaccines and newborn care (1%). The impact of IBD and surgery on fertility was ranked as the number one priority more often in the preconception group (p value < 0.01) and mode of delivery in the pregnancy group (p value 0.04). CONCLUSION: Safety of IBD medications remains a priority topic for patients seeking preconception and pregnancy counseling.
