Objective: To study compliance and effectiveness of the mHealth nutrition and lifestyle coaching program Smarter Pregnancy in couples undergoing in vitro fertilization (IVF) treatment with or without intracytoplasmic sperm injection (ICSI).Design: Multicenter, single-blinded, randomized controlled trial, conducted from July 2014 to March 2017.Setting: IVF clinics.Patient(s): A total of 626 women undergoing IVF treatment with or without ICSI and 222 male partners.Interventions(s): Couples were randomly assigned to the light (control group) or regular (intervention group) Smarter Pregnancy program. Both groups filled out a baseline screening questionnaire on nutrition and lifestyle behaviors, and the intervention group received coaching tailored to inadequate behaviors during the 24-week period.Main Outcome Measure(s): Difference in improvement of a composite dietary and lifestyle risk score for the intake of vegetables, fruits, folic acid supplements, smoking, and alcohol use after 24 weeks of the program.Result(s): Compared with control subjects, women and men in the intervention group showed a significantly larger improvement of inadequate nutrition behaviors after 24 weeks of coaching. At the same time, the women also showed a significantly larger improvement of inadequate lifestyle behaviors.Conclusion(s): The mHealth coaching program Smarter Pregnancy is effective and improves the most important nutritional and lifestyle behaviors among couples undergoing IVF/ICSI treatment. International multicenter randomized trials are recommended to study the effect of using Smarter Pregnancy on pregnancy, live birth, and neonatal outcome.Netherlands Trial Register Number: NTR4150.

Periconceptional nutrition and lifestyle are essential in pathogenesis and prevention of most reproductive failures, pregnancy outcome and future health. We aimed to investigate whether personalized mobile health (mHealth) coaching empowers couples contemplating pregnancy to increase healthy behaviour and chances of pregnancy. A survey was conducted among 1053 women and 332 male partners who received individual coaching using the mHealth programme ‘Smarter Pregnancy’ to change poor nutrition and lifestyle for 26 weeks, depending on pregnancy state and gender. Poor behaviours were translated into a total risk score (TRS) and Poisson regression analysis was performed to estimate associations with the chance of pregnancy adjusted for fertility status, age and baseline body mass index expressed as adjusted hazard ratio (aHR) and 95% confidence interval (95% CI). A lower (a)HR suggests a higher chance of achieving pregnancy. A higher TRS was significantly associated with a lower chance of pregnancy in all women (aHR 0.79, 95% CI 0.72–0.85) and (a)HR was lowest in women whose male partner participated (aHR 0.75, 95% CI 0.61–0.91). This survey shows that empowerment of couples in changing poor nutrition and lifestyle using personalized mHealth coaching is associated with an enhanced pregnancy chance in both infertile and fertile couples.

Objective To assess whether actively preparing for pregnancy by women is associated with lifestyle changes during the preconception period. Design retrospective cross-sectional study. Setting primary care community midwifery practice in the Netherlands. Participants convenience sample of 283 women who received antenatal care. Measurements and findings the association between pregnancy preparation (defined as searching for information and/or consulting a healthcare provider) and preconception lifestyle changes (healthier diet, folic acid, alcohol and tobacco cessation) was measured and adjusted for age, body mass index and educational level. Almost 60% ( n =160) of women acquired preconception information themselves and 25% ( n =68) consulted a healthcare provider regarding their pregnancy wish. The former group was significantly more likely to quit drinking (adjusted OR 5.46 (95% CI 1.76–16.96)), improve their diet (adjusted OR 7.84 (95% CI 3.03–20.30)) and use folic acid (adjusted OR 3.90 (95% CI 2.00–7.62)) compared with women who did not prepare for pregnancy. Effect sizes were even larger for women who (also) consulted a healthcare provider with regard to folic acid use, healthier diet and smoking cessation. Key conclusions gathering preconception information, either by women themselves or by means of a PCC consult, is associated with women positively changing lifestyles during the preconception period. Implications for practice we recommend to not solely focus interventions on increasing the uptake of PCC consults, yet providing a suitable offer of preconception health information, which enables women to properly inform themselves.

Women who develop preeclampsia have an increased risk of cardiovascular disease (CVD) later in life. However, current guidelines on cardiovascular risk assessment and prevention are unclear on how and when to screen these women postpartum, and about the role of a positive history of preeclampsia in later-life CVD risk management. The aim of this review is to discuss the present knowledge on commonly used cardiovascular screening modalities available to women with a history of preeclampsia, and to discuss recent developments in early detection of CVD using cardiovascular imaging. Furthermore, we explore how female-specific risk factors may have additional value in cardiovascular screening, in particular in relatively young women, although their implementation in clinical practice is challenged by inconsistent results and lack of long-term outcome data. Non-invasive imaging techniques, e.g., coronary artery intima-media thickness (CIMT), can be helpful to detect subclinical atherosclerotic disease, and coronary artery calcium scoring (CACS) has shown to be effective in early detection of cardiovascular damage. However, while more short-term and long-term follow-up studies are becoming available, few studies have investigated women with a history of preeclampsia in the fourth and fifth decade of life, when early signs of premature CVD are most likely to become apparent. Further studies are needed to inform new and improved clinical practice guidelines, and provide long-term strategies to effectively prevent CVD, specifically targeted at women with a history of preeclampsia. Additionally, evaluation of feasibility, cost-effectiveness, and implementation of CVD screening and prevention initiatives targeted at former preeclampsia patients are needed.

To explore healthcare providers' views on improving preconception care in their region. Mixed-methods study. Working conferences aimed to educate healthcare providers on preconceptional risk factors and conduct a region-specific analysis of barriers and facilitators for implementing preconception care, were organised in ten municipalities in the Netherlands. 250 healthcare providers of various disciplines attended a working conference and participated in the study. Participants were asked to both fill out a questionnaire concerning statements and experiences with preconception care and to participate in a workshop, to identify barriers and facilitators for the implementation of a local preconception care program. Almost all healthcare providers suggested that the responsibility for providing preconception care consultations lies within primary care (general practitioners (n = 239; 95.6%) and midwives (n = 236; 94.4%)). Professionals other than midwives found it significantly more difficult to start a conversation about a wish to conceive compared to midwives (26.8% versus 20.2%, p-value = 0.006) and felt less competent to provide preconceptional information (32.3% versus 15.1%, p-value = <0.001). Innovative facilitators were mentioned to improve reaching the target population with preconceptional information, i.e. the use of social media and local ambassadors. While the responsibility for providing preconception care consultations is best suited with primary care, many other healthcare providers involved may act as referrers towards preconception care. Still, approximately 1 in 7 midwives (strongly) disagree with the statement that it is part of their job to provide preconceptional information to couples with a wish to conceive. There is a need for integrating preconception care in many curricula and postgraduate courses, especially for non-midwives, to improve the delivery of preconception care. Insights in the suggested barriers and facilitators can improve the implementation of (local) preconception care programs. [ABSTRACT FROM AUTHOR]

Background: Although the evidence regarding the benefit of using ST waveform analysis of the fetal electrocardiogram is conflicting, ST waveform analysis is considered as adjunct to identify fetuses at risk for asphyxia in our center. Most randomized controlled trials and meta-analyses have not shown a significant decrease in umbilical metabolic acidosis, while some observational studies have shown a gradual decrease of this outcome over a longer period of time. Observational studies can give more insight into the effect of implementation of the ST technology in daily clinical practice.Objective: To evaluate the change in frequency of perinatal intervention and adverse neonatal outcome after the implementation of ST waveform analysis of the fetal electrocardiogram from 2000 to 2013.Study Design: This retrospective longitudinal study was conducted in a tertiary referral center. A total of 19,664 medium- and high-risk singleton pregnancies with fetuses in cephalic presentation, a gestational age of ≥36 weeks, and the intention to deliver vaginally were included. ST waveform analysis of the fetal electrocardiogram was implemented in the year 2000 and by 2010 all deliveries were monitored using this technology. Data were collected on the following perinatal outcomes: fetal blood sampling, mode of delivery, umbilical cord blood gases, Apgar scores, neonatal encephalopathy, and perinatal death. Longitudinal trend analysis was used to detect changes over time in all deliveries monitored by cardiotocography either alone or in adjunct to ST waveform analysis of the fetal electrocardiogram. Logistic regression was used to correct for possible confounders.Results: The umbilical artery metabolic acidosis rate declined from 2.5% (average rate of 2000 + 2001 + 2002) to 0.4% (average of 2011 + 2012 + 2013) (P < .001), which represents an 84% decrease. This decrease largely occurred between 2006 and 2008, during the Dutch randomized trial on fetal electrocardiogram ST waveform analysis. At this time, approximately 20% of deliveries were monitored using this method. Furthermore, there were significant reductions in fetal blood sampling rate (P < .001). Overall cesarean and vaginal instrumental deliveries decreased significantly (P < .001), but not for fetal distress. There were no changes in the Apgar scores. The incidence of neonatal encephalopathy was significantly lower in the second part of the study (odds ratio 0.39, 95% confidence interval 0.17-0.89).Conclusion: There was an 84% decrease in the incidence of umbilical artery metabolic acidosis in all deliveries between 2000 and 2013. The neonatal encephalopathy rate, fetal blood sampling rate, and the total number of cesarean and vaginal instrumental deliveries also decreased. [ABSTRACT FROM AUTHOR]

Background: Twin pregnancies are at increased risk for perinatal morbidity and death because of many factors that include a high incidence of preterm delivery. Compared with singleton pregnancies, overall perinatal risk of death is higher in twin pregnancies; however, for the preterm period, the perinatal mortality rate has been reported to be lower in twins.Objective: The purpose of this study was to compare perinatal mortality rates in relation to gestational age at birth between singleton and twin pregnancies, taking into account socioeconomic status, fetal sex, and parity.Study Design: We studied perinatal mortality rates according to gestational age at birth in 1,502,120 singletons pregnancies and 51,658 twin pregnancies without congenital malformations who were delivered between 2002 and 2010 after 28 weeks of gestation. Data were collected from the nationwide Netherlands Perinatal Registry.Results: Overall the perinatal mortality rate in twin pregnancies (6.6/1000 infants) was higher than in singleton pregnancies (4.1/1000 infants). However, in the preterm period, the perinatal mortality rate in twin pregnancies was substantially lower than in singleton pregnancies (10.4 per 1000 infants as compared with 34.5 per 1000 infants, respectively) for infants who were born at <37 weeks of gestation; this held especially for antepartum deaths. After 39 weeks of gestation, the perinatal mortality rate was higher in twin pregnancies. Differences in parity, fetal sex, and socioeconomic status did not explain the observed differences in outcome.Conclusion: Overall the perinatal mortality rate was higher in twin pregnancies than in singleton pregnancies, which is most likely caused by the high preterm birth rate in twins and not by a higher mortality rate for gestation, apart from term pregnancies. During the preterm period, the antepartum mortality rate was much lower in twin pregnancies than in singleton pregnancies. We suggest that this might be partially due to a closer monitoring of twin pregnancies, which indirectly suggests a need for closer surveillance of singleton pregnancies. [ABSTRACT FROM AUTHOR]

Objective: To compare the endocrine and cardiometabolic cord blood characteristics of offspring of mothers with polycystic ovary syndrome (PCOS) with those of healthy controls.Design: Cross-sectional case control study.Setting: University medical centers.Patient(s): Offspring from mothers with PCOS (n = 61) and healthy controls (n = 82).Intervention(s): Cord blood withdrawal from neonates.Main Outcome Measure(s): Cord blood estradiol, androstenedione, dehydroepiandrosterone sulfate (DHEAS), testosterone, sex hormone-binding globulin, free androgen index (FAI), insulin, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides, c-reactive protein, adiponectin, and leptin.Result(s): Androstenedione and leptin concentrations were increased in the offspring of women with PCOS compared with the controls: androstenedione median 2.9 (interquartile range [IQR] 2.3-3.9) nmol/L vs. 2.2 [IQR 1.6-2.7] nmol/L; and leptin median 13.6 [IQR 8.3-22.9] μg/L vs. 9.8 [IQR 6.0-16.5] μg/L. After adjusting for maternal and pregnancy-related confounders (such as maternal age, gestational age, birth weight), androstenedione appeared associated with PCOS in both male (relative change 1.36 [1.04; 1.78]) and female offspring (relative change 1.40 [1.08; 1.82]). Similarly, in male offspring the leptin concentrations appeared associated with PCOS after correction for confounders (relative change 1.55 [1.12; 2.14]). After correction for multiple testing, these associations attenuated.Conclusion(s): Observed results suggest that androstenedione concentrations are increased in the cord blood of male and female offspring of women with PCOS, although this requires confirmation. This finding would support the hypothesis that a maternal hyperandrogenic environment during pregnancy in women with PCOS may predispose their offspring to fetal hyperandrogenism. The potential associations between fetal hyperandrogenism and long-term health effects remain to be elucidated.Clinical Trial Registration Number: NCT00821379. [ABSTRACT FROM AUTHOR]

Abstract The main risk factors for important reproductive health issues such as subfertility and perinatal mortality largely originate in the periconception period. To evaluate associations between modifiable maternal lifestyle factors and periconception outcomes, a systematic search was conducted for relevant studies published from 1990 to February 2017 on Embase, Medline, Web of Science, Cochrane database, PubMed and Google Scholar. The initial search identified 6166 articles, of which 49 studies were eligible for inclusion. Fecundity (the capacity to have a live birth) showed significant inverse associations with smoking, alcohol use and poor diet. Studies regarding time to pregnancy showed a decline in fecundity ratios (the monthly conception rate among exposed relative to unexposed couples) with increasing body mass index (BMI). Furthermore, risk of first-trimester miscarriage was found to be increased in smokers, alcohol and caffeine consumers, and with increasing BMI. Vitamin supplement use showed a decrease in this risk. This review demonstrates that maternal modifiable lifestyle factors affect periconception outcomes. If couples planning a pregnancy are more aware and supported to adopt healthy lifestyles during the periconceptional 'window of opportunity', short-term reproductive health as well as health in later life and even of future generations can be further improved.

Objective The primary aim of this study was to investigate the correlation between pregnancy outcome and bile acid (BA) levels in pregnancies that were affected by intrahepatic cholestasis of pregnancy (ICP). In addition, correlations between maternal and fetal BA levels were explored. Study Design We conducted a retrospective study that included women with pruritus and BA levels ≥10 μmol/L between January 2005 and August 2012 in 3 large hospitals in the Netherlands. The study group was divided in mild (10-39 μmol/L), moderate (40-99 μmol/L), and severe (≥100 μmol/L) ICP. Main outcome measures were spontaneous preterm birth, meconium-stained amniotic fluid, asphyxia, and perinatal death. Univariate and multivariate logistic regression analysis was used to study associations between BA levels and adverse outcome. Results A total of 215 women were included. Gestational age at diagnosis and gestational age at delivery were significantly lower in the severe, as compared with the mild, ICP group ( P < .001). Spontaneous preterm birth (19.0%), meconium-stained fluid (47.6%), and perinatal death (9.5%) occurred significantly more often in cases with severe ICP. Higher BA levels were associated significantly with spontaneous preterm birth (adjusted odds ratio [aOR], 1.15; 95% confidence interval [CI], 1.03–1.28), meconium-stained amniotic fluid (aOR, 1.15; 95% CI, 1.06–1.25), and perinatal death (aOR, 1.26; 95% CI, 1.01–1.57). Maternal BA levels at diagnosis and at delivery were correlated positively with umbilical cord blood BA levels ( P = .006 and .012, respectively). Conclusion Severe ICP is associated with adverse pregnancy outcome. Levels of BA correlate between mother and fetus. [ABSTRACT FROM AUTHOR]

Which patient features predict the time to pregnancy (TTP) leading to term live birth in infertile women diagnosed with polycystic ovary syndrome (PCOS)? Prospective cohort follow-up study was completed, in which initial standardized phenotyping was conducted at two Dutch university medical centres from January 2004 to January 2014. Data were linked to the Netherlands Perinatal Registry to obtain pregnancy outcomes for each participant. All women underwent treatment according to a standardized protocol, starting with ovulation induction as first-line treatment. Predictors of pregnancies (leading to term live births) during the first year after PCOS diagnosis were evaluated. A total of 1779 consecutive women diagnosed with PCOS between January 2004 and January 2014 were included. In the first year following screening, 659 (37%) women with PCOS attained a pregnancy leading to term birth (≥37 weeks of gestational age). A higher chance of pregnancy was associated with race, smoking, body mass index (BMI), insulin, total testosterone and sex hormone-binding globulin (SHBG) concentrations (c-statistic = 0.59). Predictors of an increased chance of a live birth include White race, no current smoking, lower BMI, insulin and total testosterone concentrations, and higher SHBG concentrations. This study presents a nomogram to predict the chances of achieving a pregnancy (leading to a term live birth) within 1 year of treatment. [ABSTRACT FROM AUTHOR]

Objective: To study the presence of several maternal and neonatal complications in a cohort of women with hyperandrogenic as well as normoandrogenic polycystic ovary syndrome (PCOS) and women with PCOS who received different fertility treatments.Design: Prospective multicenter cohort study.Setting: Hospitals and midwifery practices.Patient(s): One hundred and eighty-eight women with PCOS and singleton pregnancies (study group) and 2,889 women with a naturally conceived singleton pregnancy (reference group).Intervention(s): Observational study.Main Outcome Measure(s): Maternal and neonatal pregnancy complications.Result(s): Women with PCOS had a statistically significantly increased risk of developing gestational diabetes (adjusted odds ratio [AOR] 4.15; 95% confidence interval [CI], 2.07-8.33) compared with the reference group, and their infants were more often born small for gestational age (AOR 3.76; 95% CI, 1.69-8.35). In a subgroup analysis, maternal complications were statistically significantly more often present in women with hyperandrogenic (defined as a free androgen index >4.5) PCOS (n = 76; 40% of all PCOS women) compared with those with normoandrogenic PCOS (n = 97; 52% of all PCOS women) (45% vs. 24%; P=.003); no statistically significant differences were observed between these groups regarding neonatal complications.Conclusion(s): Women with PCOS have an increased risk of maternal and neonatal pregnancy complications, especially women with the hyperandrogenic phenotype.Clinical Trial Registration Number: NCT00821379.

In this retrospective cohort study ( n = 479), the proportion of women with premature ovarian insufficiency (POI) who conceived was assessed, the reproductive characteristics of women with POI who had previously been pregnant or had never been pregnant compared, and the interval between last conception and the menopause in women with POI who had become pregnant assessed. Time to pregnancy and maternal age at first childbirth were compared between women with POI and population-based controls ( n = 2304). Women with POI who had previously been pregnant ( n = 249 [52%]) experienced menopause at a later age compared with controls (35.0 years: interquartile range [IQR] 32.0–37.5 versus 30.0 years [IQR 23.0–35.0]; P < 0.001). The median interval between last conception and menopause in the former group was 4.0 years (IQR 1.0–8.0). Time to pregnancy did not differ between women with POI and controls. Women with POI were younger at first childbirth compared with controls (27.3 years [IQR 23.4–30.5] versus 29.2 years [26.4–32.0]; P < 0.001). The reproductive capacity of young women with POI is comparable to women in the general population, up until a given age; thereafter a rapid loss of the potential to conceive occurs.

Objective To study the cardiometabolic profile characteristics and compare the prevalence of cardiovascular (CV) risk factors between women with different polycystic ovary syndrome (PCOS) phenotypes. Design A cross-sectional multicenter study analyzing 2,288 well phenotyped women with PCOS. Setting Specialized reproductive outpatient clinic. Patient(s) Women of reproductive age (18–45 years) diagnosed with PCOS. Intervention(s) Women suspected of oligo- or anovulation underwent a standardized screening consisting of a systematic medical and reproductive history taking, anthropometric measurements, and transvaginal ultrasonography followed by an extensive endocrinologic/metabolic evaluation. Main Outcome Measure(s) Differences in cardiometabolic profile characteristics and CV risk factor prevalence between women with different PCOS phenotypes, i.e., obesity/overweight, hypertension, insulin resistance, dyslipidemia, and metabolic syndrome. Result(s) Women with hyperandrogenic PCOS (n = 1,219; 53.3% of total) presented with a worse cardiometabolic profile and a higher prevalence of CV risk factors, such as obesity and overweight, insulin resistance, and metabolic syndrome, compared with women with nonhyperandrogenic PCOS. In women with nonhyperandrogenic PCOS overweight/obesity (28.5%) and dyslipidemia (low-density lipoprotein cholesterol ≥3.0 mmol/L; 52.2%) were highly prevalent. Conclusion(s) Women with hyperandrogenic PCOS have a worse cardiometabolic profile and higher prevalence of CV risk factors compared with women with nonhyperandrogenic PCOS. However, all women with PCOS should be screened for the presence of CV risk factors, since the frequently found derangements at a young age imply an elevated risk for the development of CV disease later in life.
