Abstract
AIM Women with overweight or obesity are recommended to lose weight before conception to optimize pregnancy outcomes. However, the obstetrical implications of prepregnancy weight loss have been minimally examined. The objective of this study was to investigate the association between prepregnancy weight loss and maternal metabolic and inflammatory profiles during a subsequent pregnancy. METHODS This study was a retrospective analysis of National Health and Nutrition Examination Survey data (2003-2018). Participants were women who were pregnant at the time of assessment. Prepregnancy weight loss was described as percent weight change based on self-reported baseline (1 year before pregnancy) and prepregnancy weight. Metabolic (e.g., blood pressure [BP]) and inflammatory biomarkers (i.e., high-sensitivity C-reactive protein [hs-CRP]) were determined by standard medical tests. Statistical analyses included linear regressions with appropriate imputation, weighting, and variance estimation techniques. RESULTS Participants (N = 236) reported a mean percent weight loss of 4.6% (standard error [SE] = 0.3%) during the year before pregnancy. Regression models showed that prepregnancy weight loss was inversely associated with levels of total cholesterol (β = -1.24, p = 0.01), low-density lipoprotein-cholesterol (β = -0.79, p < 0.01), and high-density lipoprotein-cholesterol (β = -0.18, p < 0.01). The effect of prepregnancy weight loss on BP, insulin sensitivity, and hs-CRP was not significant, although there was a trend toward higher levels of diastolic BP (β = 0.24, p = 0.07) and hs-CRP (β = 0.10, p = 0.08). CONCLUSIONS This study found favorable changes in lipid profiles following prepregnancy weight loss. Due to limitations such as a relatively small sample size, self-reported weight measures, and missing data on several outcome variables, future studies are needed to confirm study findings.

Abstract
PURPOSE OF REVIEW The purpose of this study was to conduct a scoping review to map intervention, sample, and physiologic measurement characteristics of lifestyle interventions for gestational diabetes mellitus (GDM) prevention. RECENT FINDINGS A total of 19 studies met selection criteria from 405 articles screened (PubMed, Web of Science). No studies were US-based (47% multi-site), and all were delivered in clinical settings. The most targeted nutrition components were low carbohydrate intake (sugar rich foods/added sugars, low glycemic index), low fat intake (mainly low-fat meat, dairy, and saturated fat), and increased fruits and vegetables. Many studies promoted 150 min/week moderate-intensity physical activity. Only two studies provided supervised physical activity sessions. Dietitians and nurses were the most common implementers. Samples were characterized as adults with obesity (mean age 31 yr, BMI 31 kg/m2). Asian populations were predominantly studied. Four studies used theoretical frameworks (75% of which used Social Cognitive Theory). GDM diagnostic criteria set forth by the American Diabetes Association were the most widely used. Insulin sensitivity was commonly assessed via fasting indices. There was a lack of multi-disciplinary, multi-level, and theory-based lifestyle interventions for reducing GDM risk. Addressing these gaps and prioritizing high-risk populations in the US with measurement of traditional and novel biomarkers will advance the field.

Effectiveness of preconception weight loss interventions on fertility in women: a systematic review and meta-analysis. Fertil Steril 2024:S0015-0282(24)00126-2. [PMID: 38408693 DOI: 10.1016/j.fertnstert.2024.02.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 02/09/2024] [Accepted: 02/19/2024] [Indexed: 02/28/2024]
Abstract
IMPORTANCE Weight loss before conception is recommended for women with overweight or obesity to improve fertility outcomes, but evidence supporting this recommendation is mixed. OBJECTIVE To examine the effectiveness of weight loss interventions using lifestyle modification and/or medication in women with overweight or obesity on pregnancy, live birth, and miscarriage. DATA SOURCES An electronic search of MEDLINE, Embase, Cochrane Library, including Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials, and Cumulative Index to Nursing and Allied Health Literature was conducted through July 6, 2022, via Wiley. STUDY SELECTION AND SYNTHESIS Randomized controlled trials examining weight loss interventions through lifestyle and/or medication in women with overweight or obesity planning pregnancy were included. Random-effects meta-analysis was conducted, reporting the risk ratio (RR) for each outcome. Subgroup analyses were conducted by intervention type, type of control group, fertility treatment, intervention length, and body mass index (BMI). MAIN OUTCOME(S) Clinical pregnancy, live birth, and miscarriage events. RESULT(S) A narrative review and meta-analysis were possible for 16 studies for pregnancy (n = 3,588), 13 for live birth (n = 3,329), and 11 for miscarriage (n = 3,248). Women randomized and exposed to a weight loss intervention were more likely to become pregnant (RR = 1.24, 95% CI 1.07-1.44; I2 = 59%) but not to have live birth (RR = 1.19, 95% CI 0.97-1.45; I2 = 69%) or miscarriage (RR = 1.17, 95% CI 0.79-1.74; I2 = 31%) compared with women in control groups. Subgroup analyses revealed women randomized to weight loss interventions lasting 12 weeks or fewer (n = 9, RR = 1.43; 95% CI 1.13-1.83) and women with a BMI ≥ 35 kg/m2 (n = 7, RR = 1.54; 95% CI, 1.18-2.02) were more likely to become pregnant compared with women in the control groups. Miscarriage was higher in intervention groups who underwent fertility treatment (n = 8, RR 1.45; 95% CI 1.07-1.96). CONCLUSION(S) Pregnancy rates were higher in women undergoing preconception weight loss interventions with no impact on live birth or miscarriage rates. Findings do not support one-size-fits-all recommendation for weight loss through lifestyle modification and/or medication in women with overweight or obesity immediately before conception to improve live birth or miscarriage outcomes.

Mothers' experiences of a lifestyle intervention for weight reduction 12 months after gestational diabetes mellitus: Qualitative findings from the PAIGE2 study. Midwifery 2024; 129:103911. [PMID: 38141456 DOI: 10.1016/j.midw.2023.103911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 11/27/2023] [Accepted: 12/19/2023] [Indexed: 12/25/2023]
Abstract
The standardised pooled prevalence of gestational diabetes mellitus (GDM) globally is approximately 14 %, a reflection of increasing rates of obesity in women of childbearing age. Lifestyle interventions to reduce GDM and subsequent type 2 diabetes (T2D) have been deemed a research priority but are challenging to perform and have variable success rates. The PAIGE2 study was a pragmatic lifestyle randomised controlled trial for women with GDM and body mass index ≥25 kg/m2, which began during pregnancy and continued for one year postnatally. The primary outcome was weight loss 12 months postnatally compared with mothers receiving standard maternity care. Qualitative results are presented from end of study focus groups conducted amongst intervention mothers to gather feedback and determine acceptability of the PAIGE2 intervention. In total, 19 mothers participated in five virtual focus groups. Content analysis explored general study experience, longer term changes to lifestyle and suggested improvements of intervention components including monthly phone calls, motivational text messages, Fitbit experience, Slimming World, and study contact timings. Overall, most mothers found the individual PAIGE2 intervention components enjoyable, although opinions differed as to which were the most effective. Several mothers claimed the intervention helped them make long-term changes to their behaviours. A common suggested improvement was the establishment of a local group where mothers could share their experiences. In conclusion, most mothers deemed the intervention acceptable, and felt that with minor enhancements, it could be utilised as an effective tool to support weight loss after pregnancy and reduce future risk of obesity and T2D.

[PMID: 37979551 DOI: 10.1016/j.midw.2023.103875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2023] [Revised: 10/30/2023] [Accepted: 11/06/2023] [Indexed: 11/20/2023]
Abstract
BACKGROUND The Saudi population is characterized by a high fertility rate, a conservative sociocultural context, and an ongoing societal and lifestyle transition. Yet, data regarding childbearing intentions and the associated factors is scarce. Furthermore, childbearing intention may be impacted by abnormal pregnancy events, such as the clinical suspicion or diagnosis of a fetal congenital disease and the negative experience that may result from it. OBJECTIVES The present study explored childbearing intention and determined the sociodemographic and health-related factors discouraging from future pregnancies among women visiting the cardiology clinic for antenatal screening of congenital heart diseases (CHD). METHODS A one-year cross-sectional study involved 150 consecutive pregnant women aged between 18 and 47 years old, who presented for antenatal screening of CHD at the fetal echocardiography clinic for, of a teaching hospital in Jeddah, Saudi Arabia. An interview-based questionnaire was administered before the clinic visit and collected sociodemographic data, obstetrical history, risk factors of congenital diseases, mothers' knowledge about fetal echocardiography and CHDs, and childbearing intention (the primary outcome). RESULTS Fetal echocardiography and CHD were correctly described by 60 % and 31.3 % of the participants respectively, while 40.7 % and 12 % recognized the association of congenital diseases with consanguinity and advanced maternal age respectively. Childbearing intentions showed 68.0 % of the participants declared desiring a future baby while the remaining 32.0 % declared having no further pregnancy expectations. Attitudes towards a hypothetical baby with CHD were positive in 97.3 % of the participants, and only 30 % declared that the fetal echocardiography results will impact their future childbearing decision. However, childbearing intention showed no significant association with knowledge or attitudes towards CHD. On the other hand, childbearing intention was independently associated with the number of children (OR=0.34; p<0.001), consanguinity with husband (OR=3.64; p = 0.010), and history of gestational diabetes (OR=0.28; p = 0.040). CONCLUSION Fertility expectations among Saudi mothers are more likely to be impacted by the personal experience and judgment of own pregnancy fitness, while no significant impact of fetal risks and events. This demonstrates a certain level of autonomy balanced with deeply rooted religious ethics yet combined with a lack of awareness about fetal and maternal risks associated with advanced maternal age and consanguinity. We emphasize the unmet need of education and family planning.

Effectiveness of pre-pregnancy lifestyle in preventing gestational diabetes mellitus-a systematic review and meta-analysis of 257,876 pregnancies. Nutr Diabetes 2023; 13:22. [PMID: 37973902 PMCID: PMC10654718 DOI: 10.1038/s41387-023-00251-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2023] [Revised: 10/03/2023] [Accepted: 11/06/2023] [Indexed: 11/19/2023] Open
Abstract
BACKGROUND Gestational Diabetes Mellitus (GDM) is hyperglycaemia first detected during pregnancy. Globally, GDM affects around 1 in 6 live births (up to 1 in 4 in low- and middle-income countries- LMICs), thus, urgent measures are needed to prevent this public health threat. OBJECTIVE To determine the effectiveness of pre-pregnancy lifestyle in preventing GDM. METHODS We searched MEDLINE, Web of science, Embase and Cochrane central register of controlled trials. Randomized control trials (RCTs), case-control studies, and cohort studies that assessed the effect of pre-pregnancy lifestyle (diet and/or physical activity based) in preventing GDM were included. Random effects model was used to calculate odds ratio (OR) with 95% confidence interval. The Cochrane ROB-2 and the Newcastle-Ottawa Scale were used for assessing the risk of bias. The protocol was registered in PROSPERO (ID: CRD42020189574) RESULTS: Database search identified 7935 studies, of which 30 studies with 257,876 pregnancies were included. Meta-analysis of the RCTs (N = 5; n = 2471) in women who received pre-pregnancy lifestyle intervention showed non-significant reduction of the risk of developing GDM (OR 0.76, 95% CI: 0.50-1.17, p = 0.21). Meta-analysis of cohort studies showed that women who were physically active pre-pregnancy (N = 4; n = 23263), those who followed a low carbohydrate/low sugar diet (N = 4; n = 25739) and those women with higher quality diet scores were 29%, 14% and 28% less likely to develop GDM respectively (OR 0.71, 95% CI: 0.57, 0.88, p = 0.002, OR 0.86, 95% CI: 0.68, 1.09, p = 0.22 and OR 0.72, 95% CI 0.60-0.87, p = 0.0006). CONCLUSION This study highlights that some components of pre-pregnancy lifestyle interventions/exposures such as diet/physical activity-based preparation/counseling, intake of vegetables, fruits, low carbohydrate/low sugar diet, higher quality diet scores and high physical activity can reduce the risk of developing gestational diabetes. Evidence from RCTs globally and the number of studies in LMICs are limited, highlighting the need for carefully designed RCTs that combine the different aspects of the lifestyle and are personalized to achieve better clinical and cost effectiveness.

Abstract
INTRODUCTION Gestational diabetes mellitus (GDM) is associated with increased risk for type 2 diabetes in the mother and cardiometabolic diseases in the child. The preconception period is an optimal window to adapt the lifestyle for improved outcomes for both mother and child. Our aim is to determine the effect of a lifestyle intervention, initiated before and continued throughout pregnancy, on maternal glucose tolerance and other maternal and infant cardiometabolic outcomes. METHODS AND ANALYSIS This ongoing randomised controlled trial has included 167 females aged 18-39 years old at increased risk for GDM who are contemplating pregnancy. The participants were randomly allocated 1:1 to an intervention or control group. The intervention consists of exercise (volume is set by a heart rate-based app and corresponds to ≥ 1 hour of weekly exercise at ≥ 80% of individual heart rate maximum), and time-restricted eating (≤ 10 hours/day window of energy intake). The primary outcome measure is glucose tolerance in gestational week 28. Maternal and offspring outcomes are measured before and during pregnancy, at delivery, and at 6-8 weeks post partum. Primary and secondary continuous outcome measures will be compared between groups based on the 'intention to treat' principle using linear mixed models. ETHICS AND DISSEMINATION The Regional Committees for Medical and Health Research Ethics in Norway has approved the study (REK 143756). The anonymised results will be submitted for publication and posted in a publicly accessible database of clinical study results. TRIAL REGISTRATION NUMBER Clinical trial gov NCT04585581.

Randomized controlled trial of prepregnancy lifestyle intervention to reduce recurrence of gestational diabetes mellitus. Am J Obstet Gynecol 2023; 229:158.e1-158.e14.

Abstract
BACKGROUND Preconception lifestyle intervention holds potential for reducing gestational diabetes mellitus, but clinical trial data are lacking. OBJECTIVE This study aimed to determine the effects of a prepregnancy weight loss intervention on gestational diabetes mellitus recurrence in women with overweight/obesity and previous gestational diabetes mellitus. STUDY DESIGN A 2-site, randomized controlled trial comparing a prepregnancy lifestyle intervention with educational control was conducted between December 2017 and February 2022. A total of 199 English- and Spanish-speaking adults with overweight/obesity and previous gestational diabetes mellitus were randomized to a 16-week prepregnancy lifestyle intervention with ongoing treatment until conception or educational control. The primary outcome was gestational diabetes mellitus recurrence. Analyses excluded 6 participants who conceived but did not have gestational diabetes mellitus ascertained by standard methods. RESULTS In the 63 (33%) women who conceived and had gestational diabetes mellitus ascertained (Ns=38/102 [37%] intervention vs 25/91 [28.0%] control; P=.17), those in the intervention group had significantly greater weight loss at 16 weeks compared with controls (4.8 [3.4-6.0] vs 0.7 [-0.9 to 2.3] kg; P=.001) and a greater proportion lost ≥5% of body weight (50.0% [17/34] vs 13.6% [3/22]; P=.005). There was no significant difference in the incidence of gestational diabetes mellitus recurrence between the intervention (57.9% [ns=23/38]) and the control group (44.0% [ns=11/25]; odds ratio, 1.8 [0.59-5.8]). Independent of group, greater prepregnancy weight loss predicted 21% lower odds of gestational diabetes mellitus recurrence (odds ratio, 0.79 [0.66-0.94]; P=.008). A ≥5% weight loss before conception reduced the odds of gestational diabetes mellitus recurrence by 82% (odds ratio, 0.18 [0.04-0.88]; P=.03). CONCLUSION Lifestyle intervention produced considerable prepregnancy weight loss but did not affect gestational diabetes mellitus rates. Given that the conception rate was 50% lower than expected, this study was underpowered.

[PMID: 37528363 PMCID: PMC10392008 DOI: 10.1186/s12884-023-05850-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Accepted: 07/12/2023] [Indexed: 08/03/2023] Open
Abstract
BACKGROUND American Indians and Alaska Natives (AI/AN) are disproportionately affected by adolescent obesity, adolescent pregnancy and gestational diabetes mellitus (GDM). GDM is associated with increased risk for perinatal death, obesity, and subsequent type 2 diabetes (T2D) for the offspring. Moreover, mothers with GDM are also at increased risk for T2D post-partum. Yet few lifestyle interventions exist to reduce GDM risk prior to pregnancy. We describe the process of adapting an existing validated preconception counseling intervention for AI/AN adolescent girls at-risk for GDM and their mothers. Perspectives and recommendations were gathered from a diverse array of stakeholders to assure the new program called Stopping GDM was culturally responsive and developed with tribal voices and perspectives represented. METHODS We conducted focus groups and individual interviews with multiple AI/AN stakeholders (n = 55). Focus groups and interviews were digitally recorded, transcribed verbatim, and analyzed using a thematic content approach to construct cross-cutting themes across the focus groups and interviews. RESULTS Four key themes emerged reflecting issues important to planning a reproductive health intervention: 1) Limited awareness, knowledge, and health education resources about GDM; 2) The importance of acknowledging traditional AI/AN values and the diversity of traditions and culture among AI/AN tribes; 3) The need to cultivate healthy decision-making skills and empower girls to make safe and healthy choices; and 4) Lack of communication about reproductive health between AI/AN mothers and daughters and between AI/AN women and health care professionals. CONCLUSION Findings have been used to inform the cultural tailoring and adaptation of an existing preconception counseling program, originally designed for non-AI/AN adolescent girls with diabetes, for AI/AN adolescents at-risk for GDM in future pregnancies.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is one of the most common metabolic dysfunction in pregnancy and as overweight and obesity are of the major risk factors. The aim of this study was to determine the effect of Information-Motivation and Behavioral skills (IMB) model-based counseling on preventing GDM in overweight and obese pregnant women. METHODS This randomized controlled trial study was conducted on 137 pregnant women in two groups; education and counseling IMB model-based for four sessions (n = 70), and antenatal usual care (AUC) (n = 67). This study was conducted on overweight and obese pregnant women, at the 12 to 16 weeks' gestation and recruited from the Prenatal Clinic of Rohani Hospital in north of Iran. Blood glucose was measured before and 8 weeks after the intervention. Descriptive and inferential statistics including mean, frequency, t-test, chi-square and ANCOVA were used. RESULTS The prevalence of GDM was lower in the intervention group than the control group (10% and 29.9%, respectively, RR = 0.33, CI 95% (0.15- 0.74) p = .004) as well as mean fasting blood glucose (Cohen's d = 0.28, p = .07), and glucose tolerance test at the first and second hour (d = 0.41 and Cohen's d = 0.73, respectively, p < .01). CONCLUSIONS A lifestyle intervention in early pregnancy by IMB counseling in overweight and obese pregnant women can be effective in decrease GDM.

Abstract
Gestational diabetes mellitus (GDM) significantly increases maternal health risks and adverse effects for the offspring. Observational studies suggest that weight loss before pregnancy may be a promising GDM prevention method. Still, biochemical pathways linking preconception weight changes with subsequent development of GDM among women who are overweight or obese remain unclear. Metabolomic assessment is a powerful approach for understanding the global biochemical pathways linking preconception weight changes and subsequent GDM. We hypothesize that many of the alterations of metabolite levels associated with GDM will change in one direction in GDM studies but will change in the opposite direction in studies focusing on lifestyle interventions for weight loss. The present review summarizes available evidence from 21 studies comparing women with GDM with healthy participants and 12 intervention studies that investigated metabolite changes that occurred during weight loss using caloric restriction and behavioral interventions. We discuss 15 metabolites, including amino acids, lipids, amines, carbohydrates, and carbohydrate derivatives. Of particular note are the altered levels of branched-chain amino acids, alanine, palmitoleic acid, lysophosphatidylcholine 18:1, and hypoxanthine because of their mechanistic links to insulin resistance and weight change. Mechanisms that may explain how these metabolite modifications contribute to GDM development in those who are overweight or obese are proposed, including insulin resistance pathways. Future nutritional metabolomics preconception intervention studies in overweight or obese are necessary to investigate whether weight loss through lifestyle intervention can reduce GDM occurrence in association with these metabolite alterations and to test the value of these metabolites as potential diagnostic biomarkers of GDM development.

Abstract
BACKGROUND Women with overweight (a body mass index of ≥ 25 kg/m2) or obesity (a body mass index of ≥ 30 kg/m2) are at greater risk of experiencing complications during pregnancy and labour than women with a healthy weight. Women who remove their long-acting reversible contraception (i.e. coils or implants) are one of the few groups of people who contact services as part of their preparation for conception, creating an opportunity to offer a weight loss intervention. OBJECTIVES The objectives were to understand if routine NHS data captured the pathway from long-acting reversible contraception removal to pregnancy and included body mass index; to identify the suitable components of a preconception weight loss intervention; and to engage with key stakeholders to determine the acceptability and feasibility of asking women with overweight/obesity to delay the removal of their long-acting reversible contraception in order to take part in a preconception weight loss intervention. DESIGN This was a preparatory mixed-methods study, assessing the acceptability and feasibility of a potential intervention, using routine NHS data and purposefully collected qualitative data. PARTICIPANTS The NHS routine data included all women with a long-acting reversible contraception code. There were three groups of participants in the surveys and interviews: health-care practitioners who remove long-acting reversible contraception; weight management consultants; and women of reproductive age with experience of overweight/obesity and of using long-acting reversible contraception. SETTING UK-based health-care practitioners recruited at professional meetings; and weight management consultants and contraceptive users recruited via social media. DATA SOURCES Anonymised routine data from UK sexual health clinics and the Clinical Practice Research Datalink, including the Pregnancy Register; and online surveys and qualitative interviews with stakeholders. RESULTS The records of 2,632,871 women aged 16-48 years showed that 318,040 had at least one long-acting reversible contraception event, with 62% of records including a body mass index. Given the identified limitations of the routine NHS data sets, it would not be feasible to reliably identify women with overweight/obesity who request a long-acting reversible contraception removal with an intention to become pregnant. Online surveys were completed by 100 health-care practitioners, four weight management consultants and 243 contraceptive users. Ten health-care practitioners and 20 long-acting reversible contraception users completed qualitative interviews. A realist-informed approach generated a hypothesised programme theory. The combination of weight discussions and the delay of long-acting reversible contraception removal was unacceptable as an intervention to contraceptive users for ethical and practical reasons. However, a preconception health intervention incorporating weight loss could be acceptable, and one potential programme is outlined. LIMITATIONS There was very limited engagement with weight management consultants, and the sample of participating stakeholders may not be representative. CONCLUSIONS An intervention that asks women to delay long-acting reversible contraception removal to participate in a preconception weight loss intervention would be neither feasible nor acceptable. A preconception health programme, including weight management, would be welcomed but requires risk communication training of health-care practitioners. FUTURE WORK Work to improve routine data sets, increase awareness of the importance of preconception health and overcome health-care practitioner barriers to discussing weight as part of preconception care is a priority.

Abstract
Background Low birth weight (LBW), including preterm birth (PTB) and small for gestational age (SGA), contributes a significant global health burden. We aimed to summarise current evidence on the effect of preconception and periconception interventions on LBW, SGA and PTB. Methods In this systematic review and meta-analysis, we searched PubMed, Embase, Cochrane Library and WHO Global Index Medicus for randomised controlled trials and quasi-experimental studies published by 28 November 2020, which assessed interventions delivered in preconception and periconception or preconception and pregnancy. Primary outcomes were LBW, SGA and PTB. Studies were categorised by intervention type and delivery during preconception and periconception or during preconception and pregnancy. Estimates were pooled using fixed-effects or random-effects restricted maximum likelihood method meta-analyses. Quality of evidence for primary outcomes was assessed using the Grades of Recommendations, Assessment, Development and Evaluation approach. Results We included 58 studies. Twenty-eight studies examined nutrition interventions (primarily micronutrient or food supplementation). Thirty studies (including one reporting a nutrition intervention) provided health interventions (general preconception health, early adverse pregnancy outcome prevention, non-communicable disease and infectious disease prevention and management). One study assessed a social intervention (reproductive planning). Studies varied in terms of specific interventions, including delivery across preconception or pregnancy, resulting in few studies for any single comparison. Overall, the evidence was generally very uncertain regarding the impact of any intervention on LBW, SGA and PTB. Additionally, preconception and periconception nutritional supplementation containing folic acid was associated with reduced risk of birth defects (10 studies, N=3 13 312, risk ratio: 0.37 (95% CI: 0.24 to 0.55), I2: 74.33%). Conclusion We found a paucity of evidence regarding the impact of preconception and periconception interventions on LBW, SGA and PTB. Further research on a wider range of interventions is required to clearly ascertain their potential effectiveness. Trial registration number This review was prospectively registered with PROSPERO (CRD42020220915).

Abstract
AIMS/HYPOTHESIS The aim of this study was to assess the interaction between genetic risk and lifestyle intervention on the occurrence of gestational diabetes mellitus (GDM) and postpartum diabetes. METHODS The RADIEL study is an RCT aimed at prevention of GDM and postpartum diabetes through lifestyle intervention. Participants with a BMI ≥30 kg/m2 and/or prior GDM were allocated to intervention and control groups before pregnancy or in early pregnancy. The study visits took place every 3 months before pregnancy, once in each trimester, and at 6 weeks and 6 and 12 months postpartum. We calculated a polygenic risk score (PRS) based on 50 risk variants for type 2 diabetes. RESULTS Altogether, 516 participants provided genetic and GDM data. The PRS was associated with higher glycaemic levels (fasting glucose and/or HbA1c) and a lower insulin secretion index in the second and third trimesters and at 12 months postpartum, as well as with a higher occurrence of GDM and glycaemic abnormalities at 12 months postpartum (n = 356). There was an interaction between the PRS and lifestyle intervention (p=0.016 during pregnancy and p=0.024 postpartum) when analysing participants who did not have GDM at the first study visit during pregnancy (n = 386). When analysing women in tertiles according to the PRS, the intervention was effective in reducing the age-adjusted occurrence of GDM only among those with the highest genetic risk (OR 0.37; 95% CI 0.17, 0.82). The risk of glycaemic abnormalities at 12 months postpartum was reduced in the same group after adjusting additionally for BMI, parity, smoking and education (OR 0.35; 95% CI 0.13, 0.97). CONCLUSIONS/INTERPRETATION Genetic predisposition to diabetes modifies the response to a lifestyle intervention aimed at prevention of GDM and postpartum diabetes. This suggests that lifestyle intervention may benefit from being tailored according to genetic risk. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT01698385.

Abstract
BACKGROUND The association between body mass index (BMI) in adolescence and gestational diabetes mellitus (GDM) has not been completely delineated. The purpose of our study was to determine the extent by which adolescent obesity increases the risk for developing GDM later in life. METHODS A retrospective cohort study including all army personnel pregnancies occurring between the years 2009-2019 was conducted. Adolescent BMI of participants was available using pre-recruitment army records. GDM and other pregnancy outcomes were compared between two groups: adolescent BMI below 30 (comparison group) and that of 30 or more (exposed group). Multivariable models were adjusted for sociodemographic factors. RESULTS Following exclusion of cases with missing or partial glucose tests, and undocumented BMI, 6877 deliveries were included in the analysis. GDM rates were higher in the exposed group (4.9% vs. 2.9%, p value-0.09). GDM rates were twice as common in the exposed group (4.9% vs. 2.9%, p value-0.09). The multivariable model, adjusted for country of birth, socio-economic class, medical profile score, maternal age, and follow-up time, confirmed an independent association between adolescent obesity and later GDM, with an adjusted odds ratio of 2.22 (CI 1.1-4.5, p value - 0.03). CONCLUSION Obesity during the adolescent years is independently associated with gestational diabetes later in life.

Abstract
Gestational diabetes mellitus (GDM) is a common complication of pregnancy and a serious public health problem. It carries significant risks of short-term and long-term adverse health effects for both mothers and their children. Risk factors, especially modifiable risk factors, must be considered to prevent GDM and its consequences. Observational studies have identified several nutritional and lifestyle factors associated with the risk of GDM. The results of intervention studies examining the effects of diet and lifestyle on the prevention of GDM are contradictory. Differences in the study populations, types and intensity of intervention, time frame of the intervention, and diagnostic criteria for GDM may explain the heterogeneity in the results of intervention studies. This review provides an overview of new diets and other factors that may help prevent GDM. The main results of epidemiological studies assessing the risk factors for GDM, as well as the results and methodological problems of intervention studies on the prevention of GDM and their meta-analyses, are discussed. In addition, the evidence that gene and lifestyle interactions influence the development of GDM, as well as prospects for increasing the effectiveness of interventions designed to prevent GDM, including new data on the possible uses of personalized diet therapy, are highlighted.

OBJECTIVE This study examined the effectiveness of a nonsurgical, preconception weight loss intervention on pregnancy outcomes in women with obesity. METHODS This was a two-arm, parallel-group randomized controlled trial. A total of 164 women with BMI 30 to 55 kg/m2 who were aged 18 to 38 years and planning pregnancy were randomized to a 12-week standard dietary intervention (SDI; n = 79) or a modified very low-energy diet (VLED; n = 85). Participants were observed for ≤48 weeks while trying for pregnancy and then during pregnancy. The primary outcome was maternal fasting plasma glucose at 26 to 28 weeks' gestation. Exploratory outcomes were individual and composite obesity-related adverse pregnancy outcomes. RESULTS Weight loss was greater in the VLED group (SDI 3.2 [0.6] kg vs. VLED 13.0 [0.5] kg, p < 0.01). In completers who had a singleton live birth (SDI 22/79 vs. VLED 35/85, p = 0.10), there was no difference in fasting glucose at 26 to 28 weeks' gestation (SDI 4.8[0.2] mmol/L vs. VLED 4.6 [0.1] mmol/L, p = 0.42). However, the composite of adverse pregnancy outcomes was significantly lower in the VLED group (p < 0.001). CONCLUSIONS Substantial prepregnancy weight loss in women with obesity does not alter fasting glucose at 26 to 28 weeks' gestation but does reduce a composite of adverse pregnancy outcomes. A better understanding of metabolic changes in pregnancy after preconception weight loss may assist in improving maternal and neonatal health outcomes.

Abstract
Background: Preconception lifestyle interventions appear promising to reduce pregnancy complications, prevent adult cardiometabolic diseases, and prevent childhood obesity. These interventions have almost exclusively been studied in populations of obese infertile women. The development of preconception lifestyle interventions targeting a broader population of overweight and obese women without a history infertility and their partners is needed. Methods: This study is a multicenter open label parallel group randomized controlled trial. Sixty-eight non-infertile women with overweight or obesity in the preconception period and their partners will be recruited from the Sherbrooke and Quebec City regions. The couples will be randomized in a 1:1 ratio to receive the Healthy for my Baby intervention or standard care in the preconception period and pregnancy. Women and their partners will be invited to take part in this lifestyle intervention which includes motivational interviews and daily self-monitoring of lifestyle goals through a mobile phone application. The primary endpoint of this study is the diet quality of women during the preconception period, which will be evaluated using the C-HEI 2007 score at baseline, 2, 4- and 6-months following study enrolment. Women's dietary quality will also be evaluated through the measure of urinary biomarkers of habitual dietary intake at baseline and 2 months in preconception, and 24–26 weeks in pregnancy. Additional indicators of women's lifestyle as well as anthropometric measures will be documented in preconception and pregnancy. For the pregnancy period, the main secondary endpoint is the pattern of gestational weight gain. Pregnancy and neonatal complications will also be evaluated. For partners, diet quality, other lifestyle habits, and anthropometric measures will be documented in the preconception and pregnancy periods. Discussion: This study will evaluate the effectiveness of a low-cost intervention designed to improve diet and other lifestyle characteristics of women in the preconception period who are overweight or obese. If the Healthy for my Baby intervention is efficacious regarding dietary measures, larger trials will be needed to evaluate the impact of this intervention on the rates of pregnancy complications, childhood obesity, and adult cardiometabolic disease.

Abstract
BACKGROUND American Indian and Alaska Native (AI/AN) women have a higher risk of gestational diabetes mellitus (GDM) and subsequent diagnosis of diabetes than do non-Hispanic White women. Healthy eating is key to weight management both prior to pregnancy and between pregnancies and can reduce the risk of developing GDM. Our research team developed an innovative preconception counseling and diabetes risk-reduction program, which includes nutrition and weight-management principles and is culturally tailored for adolescent AI/AN women. The program is entitled Stopping Gestational Diabetes Mellitus (SGDM). OBJECTIVE The purpose of this article is to examine nutrition-related information collected as a part of the formative qualitative research conducted for the development of a preconception counseling and gestational diabetes risk-reduction program, SGDM. METHODS This in-depth secondary analysis explored the original qualitative data from the needs assessment for SGDM program development. Participants included AI/AN women with a history of GDM (n = 5); AI/AN girls at risk of GDM (n = 14), and their mothers (n = 11), health care providers, and health administrators who care for AI/AN girls (n = 16); AI/AN elected leaders; and Indian health system administrators (n = 12). All focus groups and interviews were reanalyzed utilizing the following research question: "How do key stakeholders discuss food and/or nutrition in terms of gestational diabetes risk reduction for AI/AN adolescent girls?" RESULTS Three primary nutrition themes emerged: 1) AI/AN women were aware of healthy nutrition, healthy weight gainduring pregnancy, and healthy nutrition for people with type 2 diabetes, but these principles were not linked to reducing the risk of GDM; 2) participants expressed the need for education on the role of nutrition and weight management in GDM risk reduction; 3) participants shared challenges of healthful eating during and before pregnancy for AI/AN women. CONCLUSIONS These stakeholders' comments informed the development of the nutrition components of SGDM.

Protocol for a randomized controlled trial of pre-pregnancy lifestyle intervention to reduce recurrence of gestational diabetes: Gestational Diabetes Prevention/Prevención de la Diabetes Gestacional. Trials 2021; 22:256. [PMID: 33827659 PMCID: PMC8024941 DOI: 10.1186/s13063-021-05204-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Accepted: 03/17/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is associated with several maternal complications in pregnancy, including preeclampsia, preterm labor, need for induction of labor, and cesarean delivery as well as increased long-term risks of type 2 diabetes, metabolic syndrome, and cardiovascular disease. Intrauterine exposure to GDM raises the risk for complications in offspring as well, including stillbirth, macrosomia, and birth trauma, and long-term risk of metabolic disease. One of the strongest risk factors for GDM is the occurrence of GDM in a prior pregnancy. Preliminary data from epidemiologic and bariatric surgery studies suggest that reducing body weight before pregnancy can prevent the development of GDM, but no adequately powered trial has tested the effects of a maternal lifestyle intervention before pregnancy to reduce body weight and prevent GDM recurrence. METHODS The principal aim of the Gestational Diabetes Prevention/Prevención de la Diabetes Gestacional is to determine whether a lifestyle intervention to reduce body weight before pregnancy can reduce GDM recurrence. This two-site trial targets recruitment of 252 women with overweight and obesity who have previous histories of GDM and who plan to have another pregnancy in the next 1-3 years. Women are randomized within site to a comprehensive pre-pregnancy lifestyle intervention to promote weight loss with ongoing treatment until conception or an educational control group. Participants are assessed preconceptionally (at study entry, after 4 months, and at brief quarterly visits until conception), during pregnancy (at 26 weeks' gestation), and at 6 weeks postpartum. The primary outcome is GDM recurrence, and secondary outcomes include fasting glucose, biomarkers of cardiometabolic disease, prenatal and perinatal complications, and changes over time in weight, diet, physical activity, and psychosocial measures. DISCUSSION The Gestational Diabetes Prevention /Prevención de la Diabetes Gestacional is the first randomized controlled trial to evaluate the effects of a lifestyle intervention delivered before pregnancy to prevent GDM recurrence. If found effective, the proposed lifestyle intervention could lay the groundwork for shifting current treatment practices towards the interconception period and provide evidence-based preconception counseling to optimize reproductive outcomes and prevent GDM and associated health risks.

Abstract
BACKGROUND Women with elevated body mass index are encouraged to lose weight before pregnancy, but no trials have tested the effects of prepregnancy weight loss on health outcomes. OBJECTIVE This study aimed to determine whether prepregnancy weight loss reduces gestational weight gain and improves pregnancy outcomes. STUDY DESIGN Pragmatic randomized clinical trial was conducted between May 2015 and October 2019 at Kaiser Permanente Northwest, an integrated health system. Data collection was blind to condition assignment. Eligible participants were women aged 18 to 40 years with a body mass index of ≥27 kg/m2 who were planning pregnancy within 2 years. Recruitment contacts were sent to 27,665 health system members who met age and body mass index criteria; 329 women attended screening visits, and 326 were randomized. They were randomized to either a behavioral weight loss intervention or usual care control. The intervention consisted of health coaching phone sessions weekly for 6 months and then monthly for 18 months or until end of pregnancy. We used logistic regression to examine the a priori primary hypothesis that participants in the intervention would be less likely to exceed National Academy of Medicine guidelines for gestational weight gain during each trimester and overall. Secondary and exploratory outcomes included absolute weight gain before and during pregnancy and perinatal and newborn outcomes. RESULTS Of the 326 participants, 169 had singleton pregnancies lasting ≥14 weeks (analytical cohort: intervention, 89; control, 80). At baseline, mean age was 31.3±3.5 years, and body mass index was 34.8±5.8 kg/m2. Participants in the intervention group lost more weight before pregnancy than those in the control group (-0.25±0.51 vs -0.03±0.21 kg/wk; P<.001). However, participants in the intervention group gained more weight than those in the control group in the second trimester (0.42±0.26 vs 0.33±0.28 kg/wk; P=.04) and third trimester (0.56±0.37 vs 0.43±0.33 kg/wk; P=.02) and overall (13.2±8.20 vs 10.3±7.41 kg; P=.03). Nevertheless, arms did not differ in rates of exceeding gestational weight gain guidelines at any time point. Spontaneous pregnancy loss was less common in the intervention arm than in the control arm (8 [4.9%] vs 19 [11.8%]; odds ratio, 0.39 [0.16-0.92]), but we found no other differences in the secondary or exploratory outcomes. CONCLUSION Participation in the prepregnancy weight loss intervention had no effect on women's likelihood of exceeding gestational weight gain guidelines. Although the intervention group successfully lost weight before conception, the intervention group was associated with greater weight gain in late pregnancy. To effectively reduce weight throughout pregnancy and improve maternal and child outcomes, prepregnancy weight loss interventions may need to be combined with intensive weight management that continues throughout delivery.

Abstract
Carbohydrate metabolism disorders resulting in hyperglycemia are among the most common metabolic complications of pregnancy. According to 2017 data from the International Diabetes Federation (IDF), 16.2% of pregnancies are complicated with hyperglycemia, of which gestational diabetes mellitus (GDM) accounts for 86.4% of cases. Carbohydrate metabolism disorders developing during pregnancy require the patient to change her lifestyle or, in some cases, to undergo pharmaceutical treatment, which may affect various aspects of the patient’s life, including her perceived quality of life (QoL). The purpose of the present study was to evaluate levels of QoL, social support, acceptance of illness, and self-efficacy among pregnant patients with hyperglycemia. The study was performed between July 2016 and September 2017 in a group of hyperglycemic pregnant women. The following instruments were used: the World Health Organization Quality of Life—BREF (WHOQOL-BREF), the Berlin Social Support Scales (BSSS), the Acceptance of Illness Scale (AIS), the Generalized Self-Efficacy Scale (GSES) and a standardized interview questionnaire. Participants rated their overall QoL (3.64 points) higher than their overall perceived health (3.43). In terms of social support, the highest scores were obtained in terms of actually received support (3.53) and perceived available instrumental support (3.52), while the lowest in terms of support seeking (2.99) and the need for support (2.95). The mean acceptance of illness score among the hyperglycemic pregnant women that were studied was 31.37, and the mean generalized self-efficacy score was 31.58. Participants’ reported QoL in the various WHOQOL-BREF domains was associated with specific social support scales, acceptance of illness, and generalized self-efficacy.

Abstract
Obesity is a major public health problem. Children of women who were obese before or during pregnancy are at increased risk for neurobehavioral developmental problems. Whether a maternal lifestyle intervention conducted before and during pregnancy in obese women affects child neurobehavioral development is unknown. This study reports on the follow‐up of a subsample of two randomized controlled trials, the Finnish RADIEL (n = 216) and Dutch LIFEstyle (n = 305) trial. Women with a pre‐pregnancy BMI ≥29 kg/m2 wishing to conceive or who were already pregnant (<20 weeks) were allocated to a lifestyle intervention or to care as usual. Child neurodevelopment was measured with the Ages and Stages Questionnaire and child behavioral problems were measured with the Childhood Behavior Checklist (RADIEL) or the Strengths and Difficulties Questionnaire (LIFEstyle) at age 3‐6 years. We used linear and binary logistic regression analyses to assess the effects of the lifestyle interventions on children's neurobehavioral developmental scores. Follow‐up data was available from 161(38%) RADIEL and 96(32%) LIFEstyle children. Child neurodevelopmental scores did not differ significantly between children in the intervention and the control group (RADIEL:median = 275 vs. 280; LIFEstyle:median = 270 vs 267). Child behavioral problem scores did not differ significantly between children in the intervention and the control group (RADIEL:median = 22 vs. 21; LIFEstyle:median = 8 vs. 8). We did not observe considerable effects of the lifestyle interventions before or during pregnancy in obese women on child neurobehavioral development. With our sample sizes, we were not able to detect subtle differences in neurobehavioral development however.

Abstract
Background The global prevalence of obesity in women keeps increasing. The preconception period may be a window of opportunity to improve lifestyle, reduce obesity and improve cardiometabolic health. This study assessed the effect of a preconception lifestyle intervention on long-term cardiometabolic health in two randomized controlled trials (RCTs). Methods Participants of the LIFEstyle and RADIEL preconception lifestyle intervention studies with a baseline body mass index (BMI) ≥29 kg/m2 were eligible for this follow-up study. Both studies randomized between a lifestyle intervention targeting physical activity, diet and behaviour modification or usual care. We assessed cardiometabolic health 6 years after randomization. Results In the LIFEstyle study (n = 111) and RADIEL study (n = 39), no statistically significant differences between the intervention and control groups were found for body composition, blood pressure, arterial stiffness, fasting glucose, homeostasis model assessment of insulin resistance, HbA1c, lipids and high sensitive C-reactive protein levels 6 years after randomization. Participants of the LIFEstyle study who successfully lost ≥5% bodyweight or reached a BMI <29 kg/m2 during the intervention (n = 22, [44%]) had lower weight (−8.1 kg; 99% CI [−16.6 to −0.9]), BMI (−3.3 kg/m2; [−6.5 to −0.8]), waist circumference (−8.2 cm; [−15.3 to −1.3]), fasting glucose (−0.5 mmol/L; [−1.1 to −0.0]), HbA1c (−4.1 mmol/mol; [−9.1 to −0.8]), and higher HDL-C (0.3 mmol/L; [0.1–0.5]) compared with controls. Conclusion We found no evidence of improved cardiometabolic health 6 years after a preconception lifestyle intervention among overweight and obese women in two RCTs. Women who successfully lost weight during the intervention had better cardiometabolic health 6 years later, emphasizing the potential of successful preconception lifestyle improvement.
