Breastfeeding behaviours in women with obesity; associations with weight retention and the serum metabolome: a secondary analysis of UPBEAT.

Maternal obesity is associated with a decreased intention and initiation of breastfeeding as well as a shortened duration of breastfeeding. This analysis was undertaken to identify breastfeeding behaviours, and relationships with maternal anthropometry and the serum metabolome at 6-months postpartum in an ethnically diverse cohort of women with obesity. A cohort analysis of 715 women from the UK Pregnancies Better Eating and Activity Trial (UPBEAT); a multi-centre randomised controlled trial of an antenatal lifestyle intervention in women with obesity. Maternal data were collected in early pregnancy and included body mass index (BMI), socio-demographic characteristics and anthropometry. At 6-months postpartum, breastfeeding behaviours, anthropometry and 158 maternal metabolic measures from blood samples were recorded. Kaplan-Meier curves of breastfeeding duration were constructed and were stratified by obesity class (I: BMI 30.0-34.9 kg/m2, II: 35.0-39.9 kg/m2, III: ≥40.0 kg/m2). Relationships between breastfeeding behaviours, socio-demographic characteristics, the metabolome, and anthropometry were determined using regression analyses. Eighty-two percent (591/715) of the cohort-initiated breastfeeding and at the 6-month follow-up 40% (283/715) were breastfeeding exclusively or partially. Duration of exclusive breastfeeding decreased with increasing BMI: Compared to BMI class I (mean 90.4 ± 64 days) the difference in mean for classes II and III were -15.8 days (95% confidence interval: -28.5, -3.1, p < 0.05) and -16.7 (95% CI: -32.0 to -1.35, p < 0.05), respectively. Compared to no breastfeeding, any breastfeeding at 6-months postpartum was associated with improvements in metabolites towards a healthier profile, reduced weight retention by -1.81 kg (95% CI -0.75, -2.88, p < 0.05 ) and reduced anthropometric measures, including mid-upper arm and hip circumferences. The breastfeeding related changes in anthropometry were not evident in women of Black ethnicity. Greater emphasis on enabling breastfeeding for women with obesity could improve duration, women's weight management and metabolic health. The lack of breastfeeding related anthropometric effects in Black women requires further investigation. ISRCTN reference 89971375.

Resumption of ovulation in anovulatory women with PCOS and obesity is associated with reduction of 11β-hydroxyandrostenedione concentrations.

Is resumption of ovulation after a 6-month lifestyle intervention in women with PCOS and obesity associated with differential changes in endocrine and metabolic parameters (weight, insulin resistance, anti-Müllerian hormone (AMH), and androgens) compared to women with PCOS who remained anovulatory? Resumption of ovulation after a 6-month lifestyle intervention in women with PCOS and obesity is associated with changes in serum 11β-hydroxyandrostenedione (11OHA4) concentrations. Lifestyle interventions have been shown to reduce clinical and biochemical hyperandrogenism in women with PCOS. Weight loss of 5-10% may reverse anovulatory status, thereby increasing natural conception rates. However, the mechanisms underlying why some women with PCOS remain anovulatory and others resume ovulation after weight loss are unclear. Reproductive characteristics at baseline and a greater degree of change in endocrine and metabolic features with lifestyle intervention may be crucial for ovulatory response. We used data and samples originating from an earlier randomized controlled trial (RCT), which examined the efficacy of a 6-month lifestyle intervention prior to infertility treatment compared to prompt infertility treatment on live birth rate in women with obesity. A total of 577 women with obesity (BMI > 29 kg/m2) were randomized between 2009 and 2012. Anovulatory women with PCOS who were allocated to the intervention arm of the original RCT (n = 95) were included in the current analysis. We defined women as having resumed ovulation (RO+) based on the following criteria: spontaneous pregnancy; or assignment to expectant management; or IUI in natural cycles as the treatment strategy after lifestyle intervention. Steroid hormones were measured using liquid chromatography tandem mass spectrometry. Generalized estimating equations with adjustment for baseline measures and interaction between group and time was used to examine differences in changes of endocrine and metabolic parameters between RO+ (n = 34) and persistently anovulatory women (RO-, n = 61) at 3 and 6 months after intervention. At baseline, the mean ± SD age was 27.5 ± 3.6 years in the RO+ group and 27.9 ± 4.1 years in the RO- group (P = 0.65), and the mean ± SD weights were 101.2 ± 9.5 kg and 105.0 ± 14.6 kg, respectively (P = 0.13). Baseline AMH concentrations showed significant differences between RO+ and RO- women (median and interquartile range [IQR] 4.7 [3.2; 8.3] versus 7.2 [5.3; 10.8] ng/ml, respectively). Baseline androgen concentrations did not differ between the two groups. During and after lifestyle intervention, both groups showed weight loss; changes in 11OHA4 were significantly different between the RO+ and RO groups (P-value for interaction = 0.03). There was a similar trend for SHBG (interaction P-value = 0.07), and DHEA-S (interaction P-value = 0.06), with the most pronounced differences observed in the first 3 months. Other parameters, such as AMH and FAI, decreased over time but with no difference between the groups. No high-resolution transvaginal ultrasonography was used to confirm ovulatory status at the end of the lifestyle program. The small sample size may limit the robustness of the results. Reduction of androgen concentrations during and after lifestyle intervention is associated with recovery of ovulatory cycles. If our results are confirmed in other studies, androgen concentrations could be monitored during lifestyle intervention to provide individualized recommendations on the timing of resumption of ovulation in anovulatory women with PCOS and obesity.

Abstract MP45: Beyond Pregnancy: Meta-Analysis of Lifestyle Intervention for Prevention of Diabetes Mellitus in Women With Prior Gestational Diabetes Mellitus

Introduction: Among parous women,1 in 3 have a pregnancy complication, increasing chances of developing Diabetes Mellitus(DM), Hypertension, or heart disease. Lifestyle intervention is recommended to reduce cardiovascular morbidity risk after complicated pregnancies. The effect of lifestyle intervention on the risk of type 2 DM in women with prior Gestational DM (GDM) is not widely studied. Our study highlights the impact of lifestyle intervention on risk of type 2 DM in women with prior GDM. Methods: We ran a systemic literature search of PubMed, EMBASE, Clinical Trials.gov, and Google Scholar from January 2000 to August 2023 for relevant articles comparing lifestyle intervention (diet and physical activity) with standard care in women with prior GDM. The relative risk (RR) of DM with 95% confidence interval (CI) and p-values were extracted with fixed effect model using RevMan v.5.4. Results: Of 3100 articles that were screened, 28 underwent full-text review, and 11 studies met the inclusion criteria. Of 11 studies, 1661 were evaluated in intervention group (IG) and 1671 in control group (CG). The mean age of participants was 26.1-39 years, with a baseline body mass index (BMI) range (R) of 23.4-31.4 kg/m2 and a follow-up duration with R of 4-36 months. On analysis, the incidence of type 2 DM was 7.6% in IG compared to CG (10.35%). IG showed a 27% reduction in DM incidence as compared to CG, RR of 0.73(CI: 0.59-0.91) (p &lt; 0.05) (Figure 1). On meta-regression analysis, duration of lifestyle intervention (R: 4-36 months) significantly impacted the observed reduction in incident type 2 DM (p &lt; 0.05) (positive relation) as compared to baseline BMI (p = 0.21) (Figure 1). Conclusion: Our analysis highlights that lifestyle intervention in women with prior GDM positively reduces risk of type 2 DM, and intervention duration significantly impacts the long-term risk of DM and cardiovascular diseases. Further data is warranted from larger studies for stronger evidence regarding the benefits of lifestyle intervention in prior GDM patients

Effectiveness of a blended mobile-based lifestyle intervention in women with glucose intolerance after a recent history of gestational diabetes (MELINDA): a 1-year, prospective, multicentre, randomised controlled trial

Women with glucose intolerance after gestational diabetes mellitus (GDM) are at high risk to develop type 2 diabetes. Traditional lifestyle interventions in early postpartum have limited impact. We investigated the efficacy of a blended mobile-based lifestyle intervention in women with glucose intolerance after a recent history of GDM. Prospective, double-arm, non-masked, multicentre randomised controlled trial (RCT) in which women with glucose intolerance, diagnosed 6-16 weeks after a GDM-complicated pregnancy, were assigned 1:1 to a one-year blended-care, telephone- and mobile-based lifestyle program (intervention) or usual care (control). Primary endpoint was the proportion of women able to achieve their weight goal (≥5% weight loss if prepregnancy BMI ≥ 25kg/m2 or return to prepregnancy weight if prepregnancy BMI < 25kg/m2) in the intention-to-treat sample. Key secondary outcomes were frequency of glucose intolerance, diabetes and metabolic syndrome, and lifestyle-related outcomes assessed with self-administered questionnaires. The study was registered in ClinicalTrials.gov (NCT03559621). Between April 10th 2019 and May 13th 2022, 240 participants were assigned to the intervention (n=121) or control group (n=119), of which 167 (n=82 in intervention and n=85 in control group) completed the study. Primary outcome was achieved by 46.3% (56) of intervention participants compared to 43.3% (52) in the control group [odds ratio (OR) 1.13, 95% confidence interval (CI) 0.63-2.03, p=0.680; risk ratio 1.07, 95% CI (0.78-1.48)]. Women in the intervention group developed significantly less often metabolic syndrome compared to the control group [7.3% (6) vs. 16.5% (14), OR 0.40, CI (0.22-0.72), p=0.002], reported less sedentary behaviour and higher motivation for continuing healthy behaviours. In the intervention group, 84.1% (69) attended at least eight telephone sessions and 70.7% (58) used the app at least once weekly. A blended, mobile-based lifestyle intervention was not effective in achieving weight goals, but reduced the risk to develop metabolic syndrome.

Chemoprevention and Lifestyle Modifications for Risk Reduction in Sporadic and Hereditary Breast Cancer.

Female breast cancer is the most commonly diagnosed malignancy worldwide. Risk assessment helps to identify women at increased risk of breast cancer and allows the adoption of a comprehensive approach to reducing breast cancer incidence through personalized interventions, including lifestyle modification, chemoprevention, intensified surveillance with breast imaging, genetic counseling, and testing. Primary prevention means acting on modifiable risk factors to reduce breast cancer occurrence. Chemoprevention with tamoxifen, raloxifene, anastrozole, and exemestane has already shown benefits in decreasing breast cancer incidence in women at an increased risk for breast cancer. For healthy women carrying BRCA 1 or BRCA 2 pathogenic/likely pathogenic (P/LP) germline variants, the efficacy of chemoprevention is still controversial. Adopting chemoprevention strategies and the choice among agents should depend on the safety profile and risk-benefit ratio. Unfortunately, the uptake of these agents has been low. Lifestyle modifications can reduce breast cancer incidence, and the recommendations for BRCA 1 or BRCA 2 P/LP germline variant carriers are comparable to the general population. This review summarizes the most recent evidence regarding the efficacy of chemoprevention and lifestyle interventions in women with sporadic and hereditary breast cancer.

734-P: High Pancreatic-Derived Factor Level Is Relative to a Lower Remission of Early Postpartum Impaired Glucose Tolerance in Women with History of Gestational Diabetes Mellitus

Purpose: To clarify whether pancreatic derived factor (PANDER) predicted the remission of early postpartum impaired glucose tolerance (IGT) by lifestyle intervention among women with history of gestational diabetes mellitus (GDM). Methods: IGT women with GDM history in a prospective cohort study were enrolled at postpartum 4-12 weeks. Subjects were grouped based on quarters of PANDER level at recruitment. After lifestyle intervention, the oral glucose tolerance test (OGTT) was performed and insulin levels were measured at one year postpartum. The relation between PANDER and glycemic outcome was analyzed with logistic regression and receiver operating characteristic curve (ROC). Results: A total of 113 women were included. 55 (48.7%) of these IGT women were reversed to normal glucose tolerance at one year postpartum by lifestyle intervention. The odds of remission were lower in participants with high PANDER level than in those with low PANDER level. Compared those with PANDER&amp;lt;3.19ng/mL, women with PANDER&amp;gt;5.34 ng/mL, and PANDER&amp;gt;8.77ng/mL, were associated with a lower effect on remission of IGT (OR=0.31, 95%CI 0.11-0.90, P=0.031 and OR=0.12, 95%CI 0.04-0.41, P=0.001, respectively). After adjusting for other confounders, these associations remained in multivariable logistic regression. The area under the receiver operating characteristic curve (AUC) of PANDER for the remission of IGT was 0.702 (95% CI 0.595-0.809). When PANDER was combined with clinical information, the AUC reached 0.812 (95% CI 0.725-0.899) (P&amp;lt;0.001). Conclusions: High PANDER level in early postpartum was closely associated with the remission of IGT by lifestyle intervention in women with GDM history at one year postpartum. Disclosure L.Pei: None.

The Effect of Tailored Short Message Service (SMS) on Physical Activity: Results from a Three-Component Randomized Controlled Lifestyle Intervention in Women with PCOS

This analysis of secondary outcome measures of a randomized controlled trial was conducted to study the effect of a one-year three-component (cognitive behavioural therapy, diet, exercise) lifestyle intervention (LSI), with or without additional Short Message Service (SMS) support, on physical activity and aerobic capacity in overweight or obese women with polycystic ovary syndrome (PCOS). Women diagnosed with PCOS and a BMI > 25 kg/m2 were randomly assigned to LSI with SMS support (SMS+, n = 60), LSI without SMS support (SMS-, n = 63) or care as usual (CAU, n = 60) in order to lose weight. Based on results from the International Physical Activity Questionnaire (IPAQ), we found a significant within-group increase after one year for SMS+ in the high physical activity category (+31%, p < 0.01) and sitting behaviour decreased (Δ -871 min/week, p < 0.01). Moreover, the peak cycle ergometer workload increased within SMS+ (Δ +10 watts, p < 0.01). The SMS+ group also demonstrated a significantly different increase in walking metabolic equivalent of task minutes (METmin)/week compared with CAU after one year (Δ 1106 METmin/week, p < 0.05). Apart from this increase in walking activity, no other between-group differences were found in this trial. Overall, based on within-group results, SMS support seemed to help with improving physical activity and aerobic capacity and decreasing sedentary behaviour.

Research Trends of Lifestyle Intervention for Women With Obesity: A Text Network Analysis.

While the number of lifestyle intervention studies for women with obesity continues to increase, the research trends related to this topic should be evaluated through text network analysis. A total of 231 relevant studies published in international journals between 2011 and 2021 were identified. Semantic morphemes of the abstracts were refined, and a co-occurrence matrix with 117 keywords was generated using the text network analysis program NetMiner 4.3. The core keywords were determined as the top 25 in degree centrality, closeness centrality, or betweenness centrality. 'Lifestyle', 'Intervention', 'Diet', 'Exercise', 'Diabetes mellitus', 'Body', 'Composition', 'Quality of life', 'Obesity', 'Gain', 'Diet', and 'Loss' were the most frequently used keywords. The findings of this study provide a general overview of the research trends in lifestyle interventions for women with obesity and may be used as reference for future research.

Supports and Barriers to Lifestyle Interventions in Women with Gestational Diabetes Mellitus in Australia: A National Online Survey.

Gestational diabetes mellitus (GDM) affects approximately one in six pregnancies, causing a significant burden on maternal and infant health. Lifestyle interventions are first-line therapies to manage blood glucose levels (BGLs) and prevent future cardiometabolic complications. However, women with GDM experience considerable barriers to lifestyle interventions; thus, the aim of this study was to determine how women with GDM manage their condition and to identify the primary supports and barriers to lifestyle intervention participation. An online cross-sectional survey of women in Australia with a history of GDM was conducted. Questions included participant demographics, strategies used to manage BGLs, physical activity and dietary habits, and barriers and supports to lifestyle interventions. A total of 665 individuals consented and responded to the advertisement, of which 564 were eligible and provided partial or complete responses to the survey questions. Most respondents were between 35 and 39 years of age (35.5%), not pregnant (75.4%), working part-time (26.7%), university-educated (58.0%), and had only one child (40.1%). Most respondents managed their BGLs through diet (88.3%), with "low-carbohydrate" diets being the most popular (72.3%), and 46.2% of respondents were undertaking insulin therapy. Only 42.2% and 19.8% of respondents reported meeting the aerobic and strengthening exercise recommendations, respectively. Women with one child or currently pregnant expecting their first child were 1.51 times more likely (95% CI, 1.02, 2.25) to meet the aerobic exercise recommendations than those with two or more children. The most common reported barriers to lifestyle intervention participation were "lack of time" (71.4%) and "childcare" commitments (57.7%). Lifestyle interventions delivered between 6 and 12 months postpartum (59.0%), involving an exercise program (82.6%), and delivered one-on-one were the most popular (64.9%). Most women report managing their GDM with lifestyle strategies. The most common strategies reported involve approaches not currently included in the clinical practice guidelines such as reducing carbohydrate consumption. Furthermore, despite being willing to participate in lifestyle interventions, respondents report significant barriers, including lack of time and childcare commitments, whereas mentioned supports included having an online format. Lifestyle interventions for women with a history of GDM should be designed in a manner that is both tailored to the individual and considerate of existing barriers and supports to participation.

PMON206 Pregnancy Rate and Outcomes Following a Randomized Controlled Three-component Lifestyle Intervention in Women with PCOS

Abstract PCOS (polycystic ovary syndrome) is associated with overweight and obesity. Women with PCOS and overweight or obesity present with more pronounced reproductive derangements. Moreover, when pregnant, pregnancy complications such as gestational diabetes, hypertensive disorders and preterm birth seem to be more prevalent in this population. The present study is a one-year randomized controlled trial to investigate the effect of a three-component (cognitive behavioral therapy, healthy diet and physical therapy) lifestyle intervention (LSI) with or without Short Message Service (SMS) on pregnancy leading to live birth, pregnancy complications and outcomes within 24 months after the start of the lifestyle intervention compared to care as usual (CAU). We hypothesized that pre-pregnancy weight loss and the adoption of a healthy lifestyle would cause more pregnancies, shorter time to conception and less pregnancy complications. Women diagnosed with PCOS according to the Rotterdam 2003 criteria and a BMI above 25 kg/m2 were included. A total of 183 participants were randomly assigned to three groups: 1) three-component lifestyle intervention with SMS (LSI SMS+); 2) three-component lifestyle intervention without SMS (LSI SMS-); 3) care as usual (CAU): encourage to lose weight autonomously (control group). Pregnancy and neonatal outcomes were collected from the Dutch Bureau of Statistics (CBS) combined with the Dutch Perinatal registry (Perined). Within 24 months after the start of the intervention the pregnancy rate leading to live birth was 41.7% (25/60) within SMS+, 38.1% (24/63) within SMS- and 38.3% (23/60) within CAU. This was non-significant between the groups. Mean time to pregnancy for SMS+ was 18.3 months, 19.1 months for SMS- and 19.4 months for CAU (p=0.775). Gestational diabetes (LSI: 8.2% vs CAU: 21.7%, p=0.133), hypertensive disorders (LSI: 8.2% vs CAU: 13.0%, p=0.673) and preterm birth (LSI: 12.2% vs CAU: 17.4%, p=0.716) rates were all lower in the LSI groups (SMS+ and SMS- combined) compared to CAU. This trial demonstrated a non-significant positive trend in pregnancy outcomes in favor of the lifestyle intervention groups. We believe that a pre-pregnancy three-component lifestyle intervention in overweight or obese women with PCOS supports the attempts to get a healthy pregnancy by creating weight loss with positive effects on their physical and mental health.

A Pilot 6-Week Lifestyle Intervention in Women Aged 50+ in Ireland

<strong>Introduction:</strong> The deleterious effects of ageing and inactivity are compounded by the menopause which typically occurs in females aged 50+. The menopause is associated with unfavourable changes in body composition including decreased skeletal muscle mass, bone density and increased adipose tissue. This study aimed to determine the effects of a 6-week community-based intervention on nutrition knowledge and physical, metabolic, and cardiovascular health of women aged 50+ years. <strong>Methods:</strong> Nineteen participants (57 ± 6 years, 32.4 ± 7.2 kg/m²) completed the intervention consisting of 2 hours of aerobic training (home-based / participant led), 2 hours of concurrent training (instructor led) and one 60-minute health workshop per week. General nutrition knowledge was assessed using an adapted validated questionnaire. Body weight, body mass index (BMI), body composition and waist circumference were measured pre and post intervention. Lower body strength endurance and cardiovascular endurance were assessed using sit-to-stand and 6-minute walk tests respectively. Point-of-care testing determined fasting glucose and lipid profile. <strong>Results:</strong> There were significant reductions in body weight (–2.2 ± 2.0 kg, p &lt; 0.01), BMI (–0.9 ± 0.8 kg/m², p &lt; 0.05), percent body fat (–1.1 ± 0.5%, p &lt; 0.05), waist circumference (–2.4 ± 0.5 cm, p &lt; 0.05) and fasting glucose (–0.6 ± 0.8 mmol/L) post intervention. General nutrition knowledge score (5.8 ± 0.05, p &lt; 0.05), 6-minute walk test (Mdn = 82.5, IQR = 49.5, p &lt; 0.05) and sit-to-stand performance increased (11.5 ± 4.5 repetitions, p &lt; 0.05) significantly. <strong>Discussion:</strong> This intervention successfully improved body weight, BMI, body fat percent, waist circumference, fasting glucose, general nutrition knowledge, cardiovascular fitness, and lower body strength of participants. Metabolic health improved with a trend towards improved cardiovascular health.

P-627 Pregnancy Rate and Outcomes Following a Randomized Controlled Three-component Lifestyle Intervention in Women with PCOS

Abstract Study question What is the impact of a three-component lifestyle intervention on the pregnancy rate, time to pregnancy and pregnancy complications in women with polycystic ovary syndrome? Summary answer A non-significant positive trend in pregnancy outcomes was demonstrated in favor of the lifestyle intervention groups, in line with the weight loss achieved per group. What is known already PCOS (polycystic ovary syndrome) is associated with overweight and obesity. Women with PCOS and overweight or obesity present with more pronounced reproductive derangements. Moreover, when pregnant, pregnancy complications such as gestational diabetes, hypertensive disorders and preterm birth seem to be more prevalent in this population. The first line treatment for women with PCOS and overweight or obesity is a multi-component lifestyle intervention. Data on pregnancy outcomes after multi-component lifestyle interventions in women with PCOS are scarce. Study design, size, duration The present study is a one-year randomized controlled trial to investigate the effect of a three-component (cognitive behavioral therapy, healthy diet and physical therapy) lifestyle intervention (LSI) with or without Short Message Service (SMS) on pregnancy leading to live birth, pregnancy complications and outcomes within 24 months after the start of the lifestyle intervention compared to care as usual (CAU). Participants/materials, setting, methods Women diagnosed with PCOS according to the Rotterdam 2003 criteria and a BMI above 25 kg/m² were included. A total of 183 participants were randomly assigned to three groups: 1) three-component lifestyle intervention with SMS (SMS+); 2) three-component lifestyle intervention without SMS (SMS-); 3) care as usual (CAU): encourage to lose weight autonomously (control group). Pregnancy and neonatal outcomes were collected from the Dutch Bureau of Statistics (CBS) combined with the Dutch Perinatal registry (Perined). Main results and the role of chance Within 24 months after the start of the intervention the pregnancy rate leading to live birth was 41.7% (25/60) within SMS+, 38.1% (24/63) within SMS- and 38.3% (23/60) within CAU. This was non-significant between the groups. Mean time to pregnancy for SMS+ was 18.3 months, 19.1 months for SMS- and 19.4 months for CAU (p = 0.775). Gestational diabetes (LSI: 8.2% vs CAU: 21.7%, p = 0.133), hypertensive disorders (LSI: 8.2% vs CAU: 13.0%, p = 0.673) and preterm birth (LSI: 12.2% vs CAU: 17.4%, p = 0.716) rates were all lower in the LSI groups (SMS+ and SMS- combined) compared to CAU. Limitations, reasons for caution Although significantly less than the LSI groups, even the CAU group achieved weight loss, which may give an underestimation of the effect of the lifestyle intervention with regard to pregnancy outcomes. Wider implications of the findings Weight loss overall seems to have a positive effect on pregnancy outcomes, and multi-component lifestyle interventions are needed to achieve weight loss.

Effect of an antenatal diet and lifestyle intervention and maternal BMI on cord blood DNA methylation in infants of overweight and obese women: The LIMIT Randomised Controlled Trial.

To investigate the effect of an antenatal diet and lifestyle intervention, and maternal pre-pregnancy overweight or obesity, on infant cord blood DNA methylation. We measured DNA methylation in 645 cord blood samples from participants in the LIMIT study (an antenatal diet and lifestyle intervention for women with early pregnancy BMI ≥25.0 kg/m2) using the Illumina 450K BeadChip array, and tested for any differential methylation related to the intervention, and to maternal early pregnancy BMI. We also analysed differential methylation in relation to selected candidate genes. No CpG sites were significantly differentially methylated in relation to either the diet and lifestyle intervention, or with maternal early pregnancy BMI. There was no significant differential methylation in any of the selected genes related to the intervention, or to maternal BMI. We found no evidence of an effect of either antenatal diet and lifestyle, or of maternal early pregnancy BMI, on cord blood DNA methylation. ACTRN12607000161426.

1509-PUB: Effects of an Early Postpartum Lifestyle Intervention in Women with Gestational Diabetes Mellitus and Newly Diagnosed Diabetes

Very few studies have assessed short-term and long-term cardiovascular effects of an early postpartum lifestyle intervention among women with gestational diabetes mellitus and diabetes. The aim of the present study was to examine whether an early postpartum 9-month intensive lifestyle intervention can lead to weight loss and improve cardiovascular risk factors among women with both GDM and newly diagnosed diabetes, and also to investigate these effects in a long term. A total of 83 women who had GDM and were newly diagnosed as type 2 diabetes at 2.6 year after delivery participated in a 9-month intensive lifestyle intervention and a follow-up survey at 6-9 years post-intervention. A total of 68 women finished the 9-month lifestyle intervention and 39 women finished the 6-9 years post-intervention survey. During the first 9-month intervention, women lost their weight at 2.76 kg (-3.81% initial weight) , decreased their waist circumference (-2.88 cm) , body fat (-1.69%) , diastolic blood pressure (-3.49 mm Hg) , fasting glucose (-0.98 mmol/L) and HbA1c (-0.71%) . During the 6-9 years post intervention, women still lost weight (-3.49 kg; -5.14% initial weight) , decreased their waist circumference (-4.03 cm) , and body fat (-1.93%) , but slightly increased their HbA1c (0.26%) , total cholesterol (0.29 mmol/L) and triglycerides (0.17 mmol/L) . The prevalence of using glucose-lowering agents increased from 2.9% at baseline to 35.3% after the 9 month lifestyle intervention, and to 48.7% at 6-9 years post-intervention. An early postpartum 9-month intensive lifestyle intervention could have effects on weight loss, decreased HbA1c and other cardiovascular risk factors among women with GDM and newly diagnosed diabetes. The weight loss effect with a lifestyle intervention can persist for at least 6 years, however, HbA1c levels slightly increased in the long term. Disclosure G.Hu: None. J.Leng: None. H.Liu: None.

Reshaping the Gut Microbiota Through Lifestyle Interventions in Women with PCOS: A Review.

Polycystic ovary syndrome (PCOS) is an endocrine disorder evolving as a global threat to women's health. However, its multifactorial etiology causes difficulty in eliminating it. The interrelation between the gut microbiota and metabolic disorders has been trending recently, giving rise to new opportunities on the etiology and pathogenesis of PCOS. Lifestyle interventions such as healthy diet, physical exercises, and behavioral interventions such as regulation of stress and sleep cycles have been identified to improve the symptoms of PCOS across the endocrinological, metabolic and psychological scales and are recommended as the first line of treatment for PCOS. The impact of the unhealthy lifestyle factors on intestinal dysbiosis that cause PCOS is summarized in this review. This review also provides an insight on the therapeutic approaches that primarily target the gut microbiota and offers novel gut microflora-associated treatment strategies for PCOS. Further, this survey also highlights the need for the implementation of lifestyle management strategies and strongly recommends a healthy and stress-free lifestyle to promote gut health and manage PCOS.

Preconception lifestyle intervention in women with obesity and echocardiographic indices of cardiovascular health in their children

Improving maternal lifestyle before conception may prevent the adverse effects of maternal obesity on their children's future cardiovascular disease (CVD) risk. In the current study, we examined whether a preconception lifestyle intervention in women with obesity could alter echocardiographic indices of cardiovascular health in their children. Six years after a randomized controlled trial comparing the effects of a 6-month preconception lifestyle intervention in women with obesity and infertility prior to fertility care to prompt fertility care, 315 of the 341 children conceived within 24 months after randomization were eligible for this study. The intervention was aimed at weight loss (≥5% or until BMI < 29 kg/m2). Children underwent echocardiographic assessment of cardiac structure and function, conducted by a single pediatric cardiologist, blinded to group allocation. Results were adjusted for multiple variables including body surface area, age, and sex in linear regression analyses. Sixty children (32 girls, 53%) were included, mean age 6.5 years (SD 1.09). Twenty-four children (40%) were born to mothers in the intervention group. Children of mothers from the intervention group had a lower end-diastolic interventricular septum thickness (-0.88 Z-score, 95%CI -1.18 to -0.58), a lower left ventricle mass index (-8.56 g/m2, 95%CI -13.09 to -4.03), and higher peak systolic and early diastolic annular velocity of the left ventricle (1.43 cm/s 95%CI 0.65 to 2.20 and 2.39 cm/s 95%CI 0.68 to 4.11, respectively) compared to children of mothers from the control group. Children of women with obesity, who underwent a preconception lifestyle intervention, had improved cardiac structure and function; a thinner interventricular septum, lower left ventricle mass, and improved systolic and diastolic tissue Doppler velocities. Despite its high attrition rates, our study provides the first experimental human evidence suggesting that preconception lifestyle interventions may present a method of reducing CVD risk in the next generation.

Lifestyle interventions in women with polycystic ovary syndrome: A scoping systematic review of randomised evidence

ObjectiveLifestyle interventions (LSI) are recommended as first-line treatment for polycystic ovary syndrome (PCOS), yet the strength of evidence underpinning LSIs effectiveness remains unclear. We systematically reviewed the literature on LSIs in PCOS, evaluated evidence quality and summarised recommendations for clinical practice. Material and methodsWe searched MEDLINE, EMBASE and CENTRAL for all randomised trials evaluating any LSI in PCOS until April 2021. We extracted data on the LSIs’ characteristics, dietary composition, duration, implementation, compliance assessment, and reported outcomes. We evaluated the evidence gap using a network-map of evaluated interventions. ResultsWe screened 550 citations and included 79 trials (n=4659 women). Most trials were from high-income countries (57/79, 72%) over a decade ago (48/79, 61%) and enrolled obese/overweight women (57/77, 74%). BMI was the commonest reported outcome (58/79, 73%), followed by weight (49/79, 62%), and testosterone (45/79, 57%). More than half of the trials had high-risk of randomisation (51/79, 65%) and allocation bias (49/79, 62%). Only 27 were registered prospectively (27/79, 34%). Two-thirds evaluated a dietary intervention (70/79, 88%), most commonly a hypocaloric diet (32/70, 46%); nineteen evaluated a combined dietary with pharmacological intervention (19/79, 24%), six combined diet with physical or behavioural intervention (6/79, 8%), and only one trial included all four elements. ConclusionsEvidence on LSI in PCOS is of poor quality with high variations in trial design, comparisons, and outcome reporting. Hypocaloric diet is the most commonly recommended LSI intervention for primary care. Future trials are needed to evaluate pragmatic and simple LSIs in robust multicenter studies.

Body composition and cardiometabolic health across the menopause transition.

Every year, 2 million women reach menopause in the United States, and they may spend 40% or more of their life in a postmenopausal state. In the years immediately preceding menopause-known as the menopause transition (or perimenopause)-changes in hormones and body composition increase a woman's overall cardiometabolic risk. In this narrative review, we summarize the changes in weight, body composition, and body fat distribution, as well as the changes in energy intake, energy expenditure, and other cardiometabolic risk factors (lipid profile, glucose metabolism, sleep health, and vascular function), that occur during the menopause transition. We also discuss the benefits of lifestyle interventions in women in the earlier stages of menopause before these detrimental changes occur. Finally, we discuss how to include perimenopausal women in research studies so that women across the life-span are adequately represented.

Risks of overweight in the offspring of women with gestational diabetes at different developmental stages: A meta-analysis with more than half a million offspring.

We conducted a meta-analysis to evaluate the association of maternal gestational diabetes mellitus (GDM) and offspring overweight from birth to adulthood, and to assess the effects of lifestyle interventions in women with GDM on this risk of offspring overweight. We identified literature from PubMed and 12 other electronic databases and retrieved relevant literature published before October 20, 2020. Random-effects model analysis was used to calculate relative risks (RRs) of overweight and weighted mean differences of body mass index among children stratified into different developmental stages. Forty-nine cohort studies (n = 559,377) and four randomized controlled trials (n = 1277) were included. We found that offspring of women with GDM were at an increased risk for overweight with age, from 1.14 (95% confidence interval [CI]: 1.06-1.22) under 5 years, 1.37 (95% CI: 1.31-1.44) at 5 to <10 years, 2.00 (95% CI: 1.79-2.23) at 10 to <18 years, to 2.05 (95% CI: 1.65-2.55) over 18 years of age (p < 0.05 for differences among groups). However, it was not observed that lifestyle interventions for GDM decreased the elevated overweight risk (RR: 0.94, 95% CI: 0.80-1.11, I2 = 0.0%). These findings highlight the need for adopting an active and healthy lifestyle in this high-risk group.

Lifestyle and Chronic Pain in the Pelvis: State of the Art and Future Directions.

During their lifespan, many women are exposed to pain in the pelvis in relation to menstruation and pregnancy. Such pelvic pain is often considered normal and inherently linked to being a woman, which in turn leads to insufficiently offered treatment for treatable aspects related to their pain experience. Nonetheless, severe dysmenorrhea (pain during menstruation) as seen in endometriosis and pregnancy-related pelvic girdle pain, have a high impact on daily activities, school attendance and work ability. In the context of any type of chronic pain, accumulating evidence shows that an unhealthy lifestyle is associated with pain development and pain severity. Furthermore, unhealthy lifestyle habits are a suggested perpetuating factor of chronic pain. This is of specific relevance during lifespan, since a low physical activity level, poor sleep, or periods of (di)stress are all common in challenging periods of women’s lives (e.g., during menstruation, during pregnancy, in the postpartum period). This state-of-the-art paper aims to review the role of lifestyle factors on pain in the pelvis, and the added value of a lifestyle intervention on pain in women with pelvic pain. Based on the current evidence, the benefits of physical activity and exercise for women with pain in the pelvis are supported to some extent. The available evidence on lifestyle factors such as sleep, (di)stress, diet, and tobacco/alcohol use is, however, inconclusive. Very few studies are available, and the studies which are available are of general low quality. Since the role of lifestyle on the development and maintenance of pain in the pelvis, and the value of lifestyle interventions for women with pain in the pelvis are currently poorly studied, a research agenda is presented. There are a number of rationales to study the effect of promoting a healthy lifestyle (early) in a woman’s life with regard to the prevention and management of pain in the pelvis. Indeed, lifestyle interventions might have, amongst others, anti-inflammatory, stress-reducing and/or sleep-improving effects, which might positively affect the experience of pain. Research to disentangle the relationship between lifestyle factors, such as physical activity level, sleep, diet, smoking, and psychological distress, and the experience of pain in the pelvis is, therefore, needed. Studies which address the development of management strategies for adapting lifestyles that are specifically tailored to women with pain in the pelvis, and as such take hormonal status, life events and context, into account, are required. Towards clinicians, we suggest making use of the window of opportunity to prevent a potential transition from localized or periodic pain in the pelvis (e.g., dysmenorrhea or pain during pregnancy and after delivery) towards persistent chronic pain, by promoting a healthy lifestyle and applying appropriate pain management.
