Urogenital cultures and preterm birth in women with cervical cerclage: a single center retrospective cohort study.

BACKGROUND: The leading hypothesis of the pathogenesis of cervical insufficiency suggests a role of cervical inflammation. Urogenital tract infections could play a causative role in this process. To test this hypothesis in women with a cervical cerclage, we aimed to retrospectively examine the relationship between gestational age (GA) at delivery and positive urogenital cultures. METHODS: This single center retrospective study reviewed the records of all women with a singleton pregnancy that underwent cervical cerclage (n = 203) between 2010 and 2020 at the University Hospital of Leuven, Belgium. Transvaginal cerclages were categorized as history indicated (TVC I, n = 94), ultrasound indicated (TVC II, n = 79) and clinically indicated (TVC III, n = 20). Additionally, ten women received transabdominal cerclage (TAC). Urogenital cultures (vaginal and urine) were taken before and after cerclage with 4-week intervals. Urogenital cultures were reported 'positive' if urine and/or vaginal cultures showed significant growth of a microorganism. Treatment decision depended on culture growth and clinical presentation. The primary aim was to evaluate the association between the urogenital culture results and the GA at delivery, for each of the cerclage groups. Secondarily, to investigate the effect of antibiotic treatment of positive cultures on GA at delivery. RESULTS: Positive pre-cerclage urogenital cultures were associated with lower GA at delivery in TVC III (positive culture 26w4d ± 40d vs. negative 29w6d ± 54d, p = 0.036). For TVC I, GA at delivery was longer when pre-cerclage urogenital cultures were positive (positive culture 38w0d ± 26d vs. negative 35w4d ± 42d, p = 0.035). Overall post-cerclage urogenital cultures status was not associated with a different GA at delivery. Treating patients with pre- or post-cerclage positive urogenital cultures did also not change GA at delivery. CONCLUSION: Positive urogenital cultures taken before clinically indicated cerclage intervention may be associated with lower GA at delivery. However, there seems to be no benefit of antibiotic treatment or routine urogenital cultures during follow-up of asymptomatic women after cerclage placement.

The impact of self-monitoring physical and mental health via an mHealth application on postpartum weight retention: Data from the INTER-ACT RCT.

Background: Postpartum weight retention (PPWR) has many health risks. Digital self-monitoring of weight can potentially make postpartum weight management easier. We aim to test to what extent the self-monitoring of weight, steps and mental health through an mHealth application increases postpartum weight loss and reduces the odds of substantial PPWR (≥5 kg). Methods: Participants were mothers in the intervention arm of the INTER-ACT multicenter randomized controlled trial (RCT), an inter-pregnancy lifestyle intervention among mothers with excessive gestational weight gain. Participants (n=288) had access to an mHealth application to log their weight, steps and mental health between 6 weeks and 6 months postpartum. A linear multiple regression model and a logistic regression model were run to test to what extent self-monitoring via the app increases postpartum weight loss and reduces the risk of substantial PPWR. Results: Women who logged their weight more often lost more weight (B=0.03, ß=0.26, CIB =[0.01,0.05], P<0.01), and had reduced odds of substantive PPWR (OR=0.99, CIOR =[0.98, 0.999], P<.05). Mental health logging reduced the odds of substantive PPWR (OR=0.98, CIOR =[0.97, 1.00], P<0.05), but was unrelated to the amount of weight loss. Steps logging was unrelated to either weight loss or substantive PPWR. Conclusion: Mothers with excessive gestational weight gain can benefit from app-based lifestyle interventions to reduce PPWR by self-monitoring their weight. More attention to mental health in PPWR interventions is needed.

Length of hysterotomy for fetal spina bifida repair is associated with prematurity risk.

OBJECTIVE: To investigate whether prenatal repair of spina bifida aperta through mini-hysterotomy results in less prematurity, as compared to standard hysterotomy, when adjusting for known prematurity risks. METHODS: We performed a bi-centric, propensity score matched, controlled study, that is, adjusting for factors earlier reported to result in premature delivery or membrane rupture, in consecutive women having prenatal repair either through stapled hysterotomy or sutured mini-hysterotomy (≤3.5 cm). Matches were pairwise compared and cox-regression analysis was performed to define the hazard ratio of delivery <37 weeks. RESULTS: Of 346 meeting the MOMS-criteria, 78 comparable pairs were available for matched-controlled analysis. Mini-hysterotomy patients were younger and had a higher BMI. Mini-hysterotomy was associated with a 1.67-lower risk of delivery <37 weeks (hazard ratio: 0.60; 95% CI: 0.42-0.85; p = 0.004) and 1.72 for delivery <34 + 6 weeks (hazard ratio: 0.58; 95% CI: 0.34-0.97; p = 0.037). The rate of intact uterine scar at birth (mini-hysterotomy: 98.7% vs. hysterotomy: 90.4%; p = 0.070), the rate of reversal of hindbrain herniation within 1 week after surgery (88.9% vs. 97.4%; p = 0.180) and the rate of cerebrospinal fluid leakage (0% vs. 2.7%; p = 0.50) were comparable. CONCLUSION: Prenatal spina bidifa repair through mini-hysterotomy was associated with a later gestational age at delivery and a comparable intact uterus rate without apparent compromise in neuroprotection.

Effects of exposure to environmental factors on obesity-related growth parameters and leptin (LEP) methylation in children.

The prevalence of childhood obesity is rapidly increasing. Therefore, gaining more information on the role of environmental parameters is key. With overexpression of leptin (encoded by LEP) in obesity, LEP methylation might be altered by environmental exposures. This study aims to assess effects of ambient air pollution and nearby greenness on obesity-related growth and LEP methylation in early childhood. We monitored 120 mother-child pairs from conception until the age of five. Buccal swabs and anthropometric measurements of the children were taken at six months, one year, and five years old. Buccal DNA was extracted to determine LEP methylation levels. Estimates of air pollution and nearby greenness were calculated using high-resolution models. Effects of air pollution and nearby greenness on growth or LEP methylation were investigated using linear mixed effects models. Positive associations were shown for air pollution between conception and age one on impedance in six-month-olds and one-year-olds in the crude model. PM with aerodynamic diameter ≤10 (PM10) and ≤2.5 µm (PM2.5) positively associated with waist-hip-ratio and waist circumference at age five in the fully adjusted model. In early childhood, closest distance to forest negatively, and urban green and forest positively associated with weight-for-length, body mass index, and fat percentage in five-year-olds in the fully adjusted model. No significant associations for noise, and walkability on growth were seen. Negative associations were shown for smaller green clusters and positive associations for greater green clusters on LEP methylation in one-year-olds. For forest distance, walkability, noise, or all green on LEP methylation, no significant associations were found. Evidence is provided that ambient air pollution might have a significant effect on impedance and waist-hip-ratio, suggesting an increased risk of childhood obesity. Based on LEP methylation, greater green clusters might associate with a decreased risk of childhood obesity, while smaller green clusters showed the opposite.

Exteriorization of the uterus reduces fetoscopic cannula-induced stress and strain: A finite element model analysis.

OBJECTIVE: To estimate stresses and strains in the uterine wall and fetal membranes with single/multi-port fetoscopy, simulating either a percutaneous access or via exteriorized uterus. STUDY DESIGN: Finite element models based on anatomical dimensions, material properties and boundary conditions were created to simulate stresses, strains and displacements on the uterine wall and fetal membranes during simulated fetal surgery either via exteriorized uterus or percutaneous approach, and with one or three cannulas. Clinically, we measured the anatomical layer thickness and cannula entry point displacement in patients undergoing single port percutaneous fetoscopy. RESULTS: Simulations demonstrate that single port percutaneous fetoscopy increases stress on the fetal membranes (+105%, 128 to 262 kPa) and uterine wall (+115%, 0.89 to 1.9 kPa) compared to exteriorized uterine access. Using three ports increases stress by 110% (148 to 312 kPa) on membranes and 113% (1.08 to 2.3 kPa) on uterine wall. Finite Element Method showed 0.75 cm uterine entry point displacement from the cutaneous entry, while clinical measurements demonstrated displacement of more than double (1.69 ± 0.58 cm), suggesting modeled measurements may be underestimations. CONCLUSION: The stresses and strains on the fetal membranes and uterus are double as high when entering percutaneously than via an exteriorized uterus. Based on what can be clinically measured, this may be an underestimation.

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.

Mental Health during the Interpregnancy Period and the Association with Pre-Pregnancy Body Mass Index and Body Composition: Data from the INTER-ACT Randomized Controlled Trial.

Mental health problems and obesity are two common complications during pregnancy and postpartum. The preconception period is considered an appropriate period for prevention. Therefore, insights into interpregnancy mental health and the impact on weight and body composition are of interest to developing effective weight management strategies. The primary aim of this study is to assess the difference in women's mental health during the interpregnancy period and the association with pre-pregnancy body mass index (BMI) and body composition. The secondary aim is to study whether this association is affected by socio-demographic factors, interpregnancy interval and sleep. The study is a secondary analysis of the INTER-ACT e-health-supported lifestyle trial. Women were eligible if they had a subsequent pregnancy and mental health measurements at 6 weeks after childbirth and at the start of the next pregnancy (n = 276). We used univariate analyses to assess differences in mental health and performed regression analysis to assess their association with pre-pregnancy BMI and body composition at the start of the next pregnancy. Our results show a statistically significant increase in anxiety and depressive symptoms between 6 weeks after childbirth and the start of the next pregnancy (sSTAI-6 ≥ 40: +13%, p =≤ 0.001; GMDS ≥ 13: +9%, p = 0.01). Of the women who were not anxious at 6 weeks after childbirth (sSTAI < 40), more than one-third (39%) developed anxiety at the start of the next pregnancy (p =≤ 0.001). Regression analysis showed that sense of coherence (SOC-13) at the start of the next pregnancy was independently associated with women's pre-pregnancy BMI and fat percentage. We believe that the development of preconception lifestyle interventions that focus on both weight reduction and support in understanding, managing and giving meaning to stressful events (sense of coherence) may be of added value in optimizing women's preconception health.

Effect of the INTER-ACT lifestyle intervention on maternal mental health during the first year after childbirth: A randomized controlled trial.

We assess whether the INTER-ACT postpartum lifestyle intervention influences symptoms of depression and anxiety, sense of coherence and quality of life during the first year after childbirth. A total of 1047 women of the INTER-ACT RCT were randomized into the intervention (n = 542) or control arm (n = 505). The lifestyle intervention consisted of 4 face-to-face coaching sessions, supported by an e-health app. Anthropometric and mental health data were collected at baseline, end of intervention and 6-months follow-up. We applied mixed models to assess whether the evolution over time of depressive symptoms, anxiety, sense of coherence and quality of life differed between the intervention and control arm, taking into account the women's pre-pregnancy BMI. There was no statistical evidence for a difference in evolution in anxiety or quality of life between intervention and control arm. But an improvement in symptoms of depression and sense of coherence was observed in women who received the intervention, depending on the mother's pre-pregnancy BMI. Women with normal/overweight pre-pregnancy BMI, reported a decrease in EPDS between baseline and end of intervention, and the decrease was larger in the intervention arm (control arm: -0.42 (95% CI, -0.76 to -0.08); intervention arm: -0.71 (95% CI, -1.07 to -0.35)). Women with pre-pregnancy obesity showed an increase in EPDS between baseline and end of intervention, but the increase was less pronounced in the intervention arm (control arm: +0.71 (95% CI, -0.12 to 1.54); intervention arm: +0.42 (95% CI -0.42 to 1.25)). Women with a normal or obese pre-pregnancy BMI in the intervention arm showed a decrease in sense of coherence between baseline and end of intervention (-0.36) (95% CI, -1.60 to 0.88), while women with overweight pre-pregnancy showed an increase in sense of coherence (+1.53) (95% CI, -0.08 to 3.15) between baseline and end of intervention. Receiving the INTER-ACT postpartum lifestyle intervention showed improvement in depressive symptoms, in normal weight or overweight women on the short run, as well as improvement in sense of coherence in women with pre-pregnancy overweight only.

Dietary intake, physical activity and sedentary behavior and association with BMI during the transition to parenthood: a prospective dyadic study.

Introduction: Little is known on how diet, physical activity (PA) and sedentary behavior (SB) changes during pregnancy and after childbirth in primiparous couples. Moreover, it is unclear how potential behavioral changes are associated with changes in BMI. This study examined changes in diet, PA and SB, and their association with changes in BMI in couples transitioning to parenthood. Methods: Dietary intake (FFQ), PA, SB (both Actigraph GT3X accelerometers) and BMI of women and men were assessed at 12 weeks of gestation, 6 weeks and 6 months postpartum. Data were analyzed using dyadic longitudinal data analyses techniques. Results: In women, a decrease in fruit intake, an increase in alcohol intake, an increase of light-intensity PA, and a decrease in SB were observed from the beginning of pregnancy up to 6 months postpartum. Decreases in fruit intake between 6 weeks and 6 months postpartum was associated with increases in BMI. Men did not show significant dietary changes, while an increase in light-intensity PA and a decrease in moderate-to-vigorous PA (MVPA) was observed at 6 months postpartum when compared to 12 weeks of gestation. Paternal increases in "avoidance food group" intake were associated with increases in BMI between baseline and 6 weeks postpartum. No associations of changes in BMI and changes in PA and SB were found. Discussion: Not only mothers but also fathers experienced unfavorable changes in lifestyle during the transition to parenthood, with impact on BMI changes. This highlights the need to monitor unhealthy changes in lifestyle and body weight in both parents when expecting a child and after childbirth. Clinical trial registration: Clinicaltrials.gov, NCT03454958.

Normal glucose tolerant women with low glycemia during the oral glucose tolerance test have a higher risk to deliver a low birth weight infant.

Background: Data are limited on pregnancy outcomes of normal glucose tolerant (NGT) women with a low glycemic value measured during the 75g oral glucose tolerance test (OGTT). Our aim was to evaluate maternal characteristics and pregnancy outcomes of NGT women with low glycemia measured at fasting, 1-hour or 2-hour OGTT. Methods: The Belgian Diabetes in Pregnancy-N study was a multicentric prospective cohort study with 1841 pregnant women receiving an OGTT to screen for gestational diabetes (GDM). We compared the characteristics and pregnancy outcomes in NGT women according to different groups [(<3.9mmol/L), (3.9-4.2mmol/L), (4.25-4.4mmol/L) and (>4.4mmol/L)] of lowest glycemia measured during the OGTT. Pregnancy outcomes were adjusted for confounding factors such as body mass index (BMI) and gestational weight gain. Results: Of all NGT women, 10.7% (172) had low glycemia (<3.9 mmol/L) during the OGTT. Women in the lowest glycemic group (<3.9mmol/L) during the OGTT had compared to women in highest glycemic group (>4.4mmol/L, 29.9%, n=482), a better metabolic profile with a lower BMI, less insulin resistance and better beta-cell function. However, women in the lowest glycemic group had more often inadequate gestational weight gain [51.1% (67) vs. 29.5% (123); p<0.001]. Compared to the highest glycemia group, women in the lowest group had more often a birth weight <2.5Kg [adjusted OR 3.41, 95% CI (1.17-9.92); p=0.025]. Conclusion: Women with a glycemic value <3.9 mmol/L during the OGTT have a higher risk for a neonate with birth weight < 2.5Kg, which remained significant after adjustment for BMI and gestational weight gain.

Subsequent fertility, pregnancy, and gynaecological and psychological outcomes after maternal-fetal surgery for open spina bifida: A prospective cohort study.

OBJECTIVE: To determine the medium-term maternal impact of open fetal spina bifida repair. DESIGN: Prospective cohort study. SETTING: University Hospitals Leuven, Belgium. POPULATION: Mothers who had open maternal-fetal spina bifida repair between March 2012 and December 2021. METHODS: A patient-reported survey on subsequent fertility, pregnancy, and gynaecological and psychological outcomes. MAIN OUTCOME MEASURES: Complications during subsequent pregnancies, and gynaecological and psychological problems. RESULTS: Seventy-two out of 100 invited women completed the questionnaire (72%). Despite being advised not to, seven of 13 women attempting to conceive became pregnant within 2 years after fetal surgery and one woman delivered vaginally. Two of the 16 subsequent pregnancies were complicated by an open neural tube defect. One pregnancy was complicated by a placenta accreta and one pregnancy was complicated by a uterine rupture, both with good neonatal outcomes. Nearly half of respondents who did not attempt to conceive reported that this was because of their experience of the index pregnancy and caring for the index child. Three out of four respondents reported medium-term psychological problems, mostly anxiety for the health of the index child, fear for recurrence in subsequent pregnancies and feelings of guilt. CONCLUSIONS: Open maternal-fetal surgery for spina bifida did not appear to affect fertility in our cohort. Half of the attempts to conceive took place within 2 years. One uterine rupture and one placenta accreta occurred in 16 subsequent pregnancies. Most respondents reported psychological problems linked to the index pregnancy, which reinforces the need for long-term psychological support.

Association between cervical length and gestational age at birth in singleton pregnancies: a multicentric prospective cohort study in the Brazilian population.

BACKGROUND: Short cervical length measured during the second trimester of pregnancy is an important risk factor for spontaneous preterm birth (sPTB). The aim of this study is to identify the association between mid-pregnancy cervical length (CL) and gestational age at birth in asymptomatic singleton pregnant women. METHODS: This is a prospective cohort study involving singleton pregnant women who participated in the screening phase of a Brazilian multicenter randomized controlled trial (P5 trial) between July 2015 and March 2019. Transvaginal ultrasound to measure CL was performed from 18 to 22 + 6 weeks. Women with CL ≤ 30 mm received vaginal progesterone (200 mg/day) until 36 weeks' gestation. For this analysis we considered all women with CL ≤ 30 mm receiving progesterone and a random selection of women with CL > 30 mm, keeping the populational distribution of CL. We obtained prognostic effectiveness data (area under receive operating characteristic curve (AUC), sensitivity and specificity and estimated Kaplan-Meier curves for preterm birth using different CL cutoff points. RESULTS: We report on 3139 women and identified a negative association between cervical length and sPTB. CL ≤ 25 mm was associated with sPTB < 28, sPTB < 34 and sPTB < 37 weeks, whereas a CL 25-30 mm was directly associated with late sPTB. CL by transvaginal ultrasound presented an AUC of 0.82 to predict sPTB < 28 weeks and 0.67 for sPTB < 34 weeks. Almost half of the sPTB occurred in nulliparous women and CL ≤ 30 mm was associated with sPTB at < 37 weeks (OR = 7.84; 95%CI = 5.5-11.1). The number needed to screen to detect one sPTB < 34 weeks in women with CL ≤ 25 mm is 121 and we estimated that 248 screening tests are necessary to prevent one sPTB < 34 weeks using progesterone prophylaxis. CONCLUSIONS: CL measured by transvaginal ultrasound should be used to predict sPTB < 34 weeks. Women with CL ≤ 30 mm are at increased risk for late sPTB.

[Diagnosis and management of a foetus with congenital high airway obstruction syndrome (CHAOS)]. / Cas clinique. Diagnostic et prise en charge d'un fœtus porteur d'un syndrome d'obstruction congénitale des voies respiratoires supérieures (CHAOS).

Congenital high airway obstruction syndrome is a rare malformation whose prognosis is very poor resulting in foetal or perinatal death if no perinatal intervention is performed. However, ultrasound and magnetic resonance enable an accurate prenatal diagnosis and optimal choice of interventional foetal medicine techniques (transtracheal puncture, fetoscopy). These approaches reduce foetal side effects related to the pathological process, and avoid the mother ex utero intrapartal treatment and its deleterious effects. If it becomes indispensable ex utero intrapartal treatment allows optimal management of the new born by securing the foetal airways while minimizing risk for hypoxic damage through the maintenance of maternal-foetal circulation. We present the story of a couple with a suspected case of CHAOS at 21 weeks of amenorrhea, the diagnostic and the management until the birth of the child.

Le syndrome d'obstruction congénitale des voies respiratoires supérieures est une malformation rare dont le pronostic est très péjoratif sans intervention périnatale, entraînant un décès in utero ou à la naissance. L'échographie et la résonance magnétique nucléaire permettent de poser un diagnostic prénatal précis et de choisir les techniques de médecine fœtale interventionnelle les mieux adaptées (ponction trachéale sous contrôle échographique, reperméabilisation sous fœtoscopie). Ces approches réduisent les effets secondaires fœtaux liés au processus pathologique, et évitent à la mère le traitement intrapartal ex utero et ses effets délétères. S'il devient indispensable, le traitement intrapartal ex utero permet une prise en charge optimale du nouveau-né en sécurisant ses voies respiratoires, tout en minimisant les dommages hypoxiques, grâce au maintien de la circulation materno-foetale. Nous présentons l'histoire d'un couple confronté à une suspicion de CHAOS à 21 semaines d'aménorrhée, le parcours diagnostique et la prise en charge jusqu'à la naissance de l'enfant.

Preterm birth during the COVID-19 pandemic: more, less, or just the same?

OBJECTIVES: Coronavirus disease (COVID-19) and its mitigation measures have been associated with changes in preterm birth (PTB) incidences. The objective of this paper is to summarize and comment on the literature on COVID-19 and PTB and to compare PTB incidence between 2019 (pre-COVID-19) and 2020 (COVID-19) in three Belgian tertiary care hospitals. METHODS: A non-systematic review on COVID-19 and PTB was performed, and literature was summarized in a table. Preterm birth rates at Ghent University Hospital, Ziekenhuis Oost-Limburg, and University Hospital Leuven in 2019 and 2020 were compared. Chi-square and Fisher's exact tests were used to compare PTB rates between 2019 and 2020, and Kaplan Meier survival analysis was used to compare pregnancy duration. The mean outcome measure was PTB incidence in 2020 (COVID-19) compared with PTB incidence in 2019 (pre-COVID-19). RESULTS: Some (parts of) countries report decreases in PTB rates, others report no differences in incidence, and a minority of countries report an increased incidence of PTB. Almost all studies only consider live-births. In three tertiary care hospitals in Flanders, there were no differences in PTB rates before and during the COVID-19 pandemic. CONCLUSION: The impact of the (mitigation measures during the) COVID-19 pandemic on PTB incidence is unclear and difficult to explore. To enable a correct interpretation, all conceptions before and during the pandemic should be taken into consideration, as well as all births, still or alive.

Changes in maternal and paternal body composition during the transition to parenthood (TRANSPARENTS).

OBJECTIVE: The transition to parenthood might negatively influence health-related behavior and can result in increased adiposity. The aim of this study was to investigate how body composition in mother-father dyads changes from pregnancy up to 6 months post partum. METHODS: Anthropometrics were collected from 144 nulliparous couples at 12 weeks of gestation (PG12) and 6 weeks (PP6WK) and 6 months (PP6M) post partum. A longitudinal dyadic confirmatory factor analysis model was used to analyze changes in body composition. Body composition was treated as a latent variable using BMI, body fat percentage, and waist circumference as indicators. RESULTS: For women, latent means increased at 6 weeks post partum (PP6WK - PG12: +1.115, SE: 0.117, p < 0.001), decreased again at 6 months post partum (PP6M - PP6WK: -0.368, SE: 0.107, p < 0.001), but remained above baseline levels (PP6M - PG12: +0.747; SE: 0.115, p < 0.001). For men, the latent means at follow-up were higher than at baseline (PP6WK-PG12: +0.370, SE: 0.075; PP6M-PG12: +0.366, SE: 0.084, both p < 0.001). CONCLUSIONS: Increases in latent means correspond to unfavorable changes in BMI, body fat percentage, and waist circumference. These changes were observed from the beginning of pregnancy up to 6 months post partum. Weight management for both women and men during pregnancy and the early postpartum period is recommended and fathers should be included in pre- and postnatal standard care.

Low Gestational Weight Gain in Women With Gestational Diabetes Is Safe With Better Metabolic Profile Postpartum.

CONTEXT: More data are needed on the potential benefits and risks of gestational weight gain (GWG) less than recommended and excessive GWG in women with gestational diabetes (GDM) compared to women with normal glucose tolerance (NGT) during pregnancy. OBJECTIVE: This work aimed to evaluate association of gestational weight gain (GWG) as low, within, or above (excessive) according to Institute of Medicine (IOM) guidelines, with pregnancy outcomes in women with gestational diabetes (GDM) and normal glucose tolerance (NGT). METHODS: This prospective cohort study included 7 Belgian hospitals and 1843 women receiving universal GDM screening with a 75-g oral glucose tolerance test. Pregnancy outcomes and postpartum characteristics were the main outcome measures. RESULTS: Women with GDM and low GWG (n = 97, 52.4%) had similar rates of small-for-gestational age infants and preterm delivery, were less often overweight or obese postpartum (35.7% [30] vs 56.5% [26]; P < .022) and less often had postpartum weight retention (PPWR) (48.8% [41] vs 87.9% [40]; P < .001) compared to GWG within range (n = 58, 31.3%). GDM with excessive GWG (n = 30, 16.2%) more often had neonatal hypoglycemia (30.8% (8) vs 5.9% [3], aOR 7.15; 95% CI, 1.52-33.63; P = .013) compared to GWG within range. NGT with excessive GWG (28.3% [383]) more often had instrumental delivery (15.9% [61] vs 11.9% [64], aOR 1.53; 95% CI, 1.03-2.27; P = .035) and more large-for-gestational age infants (19.3% [74] vs 10.4% [56], aOR 1.67; 95% CI, 1.13-2.47; P = .012) compared to GWG within range. CONCLUSION: GWG below IOM guidelines occurred frequently in GDM women, without increased risk for adverse pregnancy outcomes and with better metabolic profile postpartum. Excessive GWG was associated with increased risk for neonatal hypoglycemia and worse metabolic profile postpartum in women with GDM, and with higher rates of LGA and instrumental delivery in NGT women.

Effect of the e-health supported INTER-ACT lifestyle intervention on postpartum weight retention and body composition, and associations with lifestyle behavior: A randomized controlled trial.

We investigated whether a postpartum lifestyle intervention reduced postpartum weight retention (PPWR) and improved body composition, and whether improved lifestyle was associated with less PPWR and improved body composition. A total of 1075 women with excessive gestational weight gain were randomized into the intervention (N = 551) or control (N = 524) group. A completion rate of 76% was reached. Anthropometrics and lifestyle data were collected at 6 weeks and 6 months postpartum. The e-health supported intervention consisted of 4 face-to-face coaching's, focusing on nutrition, exercise and mental wellbeing and using motivational interviewing and behavior change techniques. In the intervention group we observed; larger decrease in weight in women who reduced their energy intake (mean ± SD: 3.1 ± 4.2 kg vs. 2.2 ± 3.8 kg, P = 0.05) and decreased uncontrolled eating (3.5 ± 4.2 kg vs. 1.9 ± 3.7 kg, P ≤0.001) by the end of the intervention; larger decrease in fat percentage in women who reduced energy intake (2.3% ± 2.9 vs. 1.4% ± 2.7, P = 0.01), enhanced restrained eating (2.2% ± 3 vs. 1.4% ± 2.6, P = 0.02) and decreased uncontrolled eating (2.3% ± 2.9 vs. 1.5% ± 2.7, P = 0.01) and larger decrease in waist circumference in women who reduced energy intake (4.6 cm ± 4.8 vs. 3.3 cm ± 4.7, P = 0.01), enhanced restrained eating (4.5 cm ± 4.8 vs. 3.4 cm ± 4.8, P = 0.05) and decreased uncontrolled eating (4.7 cm ± 4.8 vs. 3.3 cm ± 4.8, P = 0.006), compared to those who did not. Improved energy intake, restrained eating and uncontrolled eating behavior were associated with more favorable outcomes in weight and body composition. ClinicalTrials.gov identifier:NCT02989142.

Mental health after childbirth and the impact on postpartum weight retention and body composition. Data from the INTER-ACT randomized controlled trial.

OBJECTIVE: To study the evolution of maternal mental health during the first year after childbirth in women with previous excessive gestational weight gain, and the relationship with postpartum weight retention and body composition. METHODS: Anthropometric and mental health data of 505 women of the INTER-ACT RCT control group were collected and assessed using descriptive statistics and mixed model analyses. RESULTS: At 6 weeks postpartum 28% of women reported depressive symptoms, 46% anxiety, 47% low sense of coherence and 48% low quality of life. From 6 weeks to 12 months postpartum there was a monthly increase (+0.38, p = .003) in anxiety and a monthly decrease (-0.39, p = .008) in quality of life. High levels of depressive symptoms at 6 weeks postpartum predicted higher body fat (+0.9%, p = .01) and higher waist circumference (+1.3 cm, p = .02) in the first year postpartum. High sense of coherence at 6 weeks postpartum predicted lower body fat (-0.8%, p = .01) the first year postpartum. CONCLUSIONS: In women with a history of excessive gestational weight gain, the first year after childbirth is characterized by a high prevalence of mental health problems in which levels of anxiety and quality of life deteriorate over time. Moreover, high levels of depressive symptoms and low sense of coherence in the first weeks postpartum predict unfavourable body composition outcomes in the year after childbirth.

Association between perceived partner support and lifestyle in mother-father dyads expecting a first child.

Background: A healthy lifestyle during pregnancy is important for the health of mother and child. However, unfavorable physical activity (PA) and dietary changes are observed in pregnant women and their partner. Partner's influence on lifestyle has been reported by expectant women and men. The first aim was to analyze associations between perceived partner support on expectant parents own as well as their partner's moderate-to-vigorous intensity PA (MVPA) levels and dietary intake. Secondly, this study aimed to investigate intra-couple associations of MVPA, dietary intake and perceived support. Methods: A total of 152 heterosexual couples were recruited between week 8 and 10 of gestation by means of convenience sampling. Objective anthropometric and 7-day MVPA measurements were performed at 12 weeks of gestation. An online questionnaire was used to assess dietary intake, perceived partner support and socio-demographic characteristics. An Actor-Partner Interdependence Model for distinguishable dyads was constructed to examine the relationship between perceived partner support and both own's (i.e., actor-effect) and the partner's (i.e., partner-effect) MVPA levels, intake of fruits and vegetables, and an "avoidance food group." Results: For pregnant women, perceived support from their partner was significantly associated with women's own MVPA levels (i.e., actor-effect; estimate = 0.344, SE = 0.168, p = 0.040) as well as the MVPA levels of the men (i.e., partner-effect; estimate = 0.717, SE = 0.255, p = 0.005). No significant actor- nor partner-effects were found for the expectant fathers. For none of the sexes significant actor-effects were found for fruit/vegetables and "avoidance food group" intake. For pregnant women, there was a positive partner-effect for fruit and vegetable intake (estimate = 7.822, SE = 1.842, p < 0.001) and a negative partner-effect for the "avoidance food group" intake (estimate = -16.115, SE = 3.629, p < 0.001). Positive correlations were found for perceived MVPA support (r = 0.40, p < 0.001), MVPA levels (r = 0.24, p = 0.007) and food intake from the "avoidance food group" (r = 0.28, p = 0.005) between partners. Conclusion: This study shows that male partners can act as significant facilitators for women. Partners may be an important target when promoting MVPA during pregnancy. Additionally, supportive couples seem to strengthen each other in keeping a healthy lifestyle in early pregnancy. These results justify couple-based interventions in the promotion of a healthy lifestyle during the transition to parenthood. Clinical trial registration: Clinicaltrials.gov, identifier: NCT03454958.
