Aims: The aim of the study was to examine the content and impact of interventions that have been used to increase the uptake of pre‐pregnancy care for women with type 2 diabetes, and their impact on maternal and fetal outcomes. Methods: A systematic search of multiple databases was conducted in November 2021, and updated July 2022, to identify studies assessing interventions to enhance pre‐pregnancy care for women with type 2 diabetes. Over 10% of articles were screened by two reviewers at title and abstract phase, after which all selected full‐text articles were screened by two reviewers. Quality assessment was conducted using the Critical Appraisal Skills Programme checklist for cohort studies. Meta‐analysis was not possible due to study heterogeneity; therefore, narrative synthesis was conducted. Results: Four eligible cohort studies were identified. The conclusions able to be drawn by this review were limited as women with type 2 diabetes (n = 800) were in the minority in all four studies (35%–40%) and none of the interventions were exclusively tailored for them. The uptake of pre‐pregnancy care was lower in women with type 2 diabetes (8%–10%) compared with other participant groups in the studies. Pregnancy preparation indicators generally improved among all groups exposed to pre‐pregnancy care, with varying impact on pregnancy outcomes. Conclusions: This review demonstrates that previous interventions have had a limited impact on pre‐pregnancy care uptake in women with type 2 diabetes. Future studies should focus on tailored interventions for improving pre‐pregnancy care for women with type 2 diabetes, particularly those from ethnic minorities and living in poorer communities.

This year's diabetes pregnancy manuscripts, three for each of type 1 diabetes (T1D), type 2 diabetes (T2D), and gestational diabetes mellitus (GDM), were chosen from over 3500 published articles. Data were collected on pregnant women with diabetes (any type) with DKA events (cases) and pregnant women with diabetes without DKA (controls) from 194 maternity units between April 2019 and September 2020. Another concerning finding is the prevalence of diabetic ketoacidosis (DKA) during pregnancy in all types of diabetes. Seventy DKA events (85%) occurred in women with T1D (incidence 16.6/100,000; 95% CI, 13.0-20.9), 5 DKA events (6%) in women with T2D (incidence 1.1/100,000; 95% CI, 0.4-2.5), and 7 (9%) in women diagnosed with GDM.

Type 1 diabetes in pregnancy is associated with an increased risk of complications for both mother and fetus. However, managing glycaemia during pregnancy to reduce these risks is challenging, owing to changes in insulin resistance with advancing gestation, as well as increased daily variation in insulin pharmacokinetics. These factors can add significant psychological and daily self-care burden to mothers during what may already be an anxious time. Increasingly, diabetes technologies are being used during pregnancy to improve and facilitate diabetes self-care. While these can be empowering for people with type 1 diabetes, careful consideration is required in relation to how and when these can be continued safely in the inpatient setting (including acute antenatal admissions, labour and delivery) and when extra support is required from adequately trained healthcare professionals. This article describes current forms of diabetes technologies used and the latest national guidance relating to the care of type 1 diabetes in pregnancy. [ABSTRACT FROM AUTHOR]

Gestational diabetes mellitus (GDM) traditionally refers to abnormal glucose tolerance with onset or first recognition during pregnancy. GDM has long been associated with obstetric and neonatal complications primarily relating to higher infant birthweight and is increasingly recognized as a risk factor for future maternal and offspring cardiometabolic disease. The prevalence of GDM continues to rise internationally due to epidemiological factors including the increase in background rates of obesity in women of reproductive age and rising maternal age and the implementation of the revised International Association of the Diabetes and Pregnancy Study Groups' criteria and diagnostic procedures for GDM. The current lack of international consensus for the diagnosis of GDM reflects its complex historical evolution and pragmatic antenatal resource considerations given GDM is now 1 of the most common complications of pregnancy. Regardless, the contemporary clinical approach to GDM should be informed not only by its short-term complications but also by its longer term prognosis. Recent data demonstrate the effect of early in utero exposure to maternal hyperglycemia, with evidence for fetal overgrowth present prior to the traditional diagnosis of GDM from 24 weeks' gestation, as well as the durable adverse impact of maternal hyperglycemia on child and adolescent metabolism. The major contribution of GDM to the global epidemic of intergenerational cardiometabolic disease highlights the importance of identifying GDM as an early risk factor for type 2 diabetes and cardiovascular disease, broadening the prevailing clinical approach to address longer term maternal and offspring complications following a diagnosis of GDM.

Similarly, in late pregnancy, women with type 2 diabetes were more likely to have anxiety symptoms (31 vs 11%; I P i =0.002) and depressive symptoms (23 vs 4%; I P i =0.002) compared to women without diabetes. Compared to women without diabetes, those with type 2 diabetes were more likely to have both anxiety symptoms (36 vs 6%; I P i <0.001) and depressive symptoms (14 vs 2%; I P i =0.003) in early pregnancy. Conclusions While mean sensor glucose over 24 h and overnight were similar between IS-CGM and RT-CGM, time below range overnight was higher when assessed using IS-CGM compared to masked RT-CGM in early pregnancy. The manuscripts chosen for this yearbook address key controversies in the screening and detection of gestational diabetes mellitus (GDM), glycemic metrics using intermittent and continuous glucose monitoring (CGM) in type 1 diabetes and the theory of beta-cell regeneration.

Aims: To undertake a Priority Setting Partnership (PSP) to establish priorities for future research in diabetes and pregnancy, according to women with experience of pregnancy, and planning pregnancy, with any type of diabetes, their support networks and healthcare professionals. Methods: The PSP used established James Lind Alliance (JLA) methodology working with women and their support networks and healthcare professionals UK‐wide. Unanswered questions about the time before, during or after pregnancy with any type of diabetes were identified using an online survey and broad‐level literature search. A second survey identified a shortlist of questions for final prioritisation at an online consensus development workshop. Results: There were 466 responses (32% healthcare professionals) to the initial survey, with 1161 questions, which were aggregated into 60 unanswered questions. There were 614 responses (20% healthcare professionals) to the second survey and 18 questions shortlisted for ranking at the workshop. The top 10 questions were: diabetes technology, the best test for diabetes during pregnancy, diet and lifestyle interventions for diabetes management during pregnancy, emotional and well‐being needs of women with diabetes pre‐ to post‐pregnancy, safe full‐term birth, post‐natal care and support needs of women, diagnosis and management late in pregnancy, prevention of other types of diabetes in women with gestational diabetes, women's labour and birth experiences and choices and improving planning pregnancy. Conclusions: These research priorities provide guidance for research funders and researchers to target research in diabetes and pregnancy that will achieve greatest value and impact.

Aims/hypothesis: Maternal hyperglycaemia alone does not explain the incidence of large offspring amongst women with type 1 diabetes. The objective of the study was to determine if there is an association between placental function, as measured by angiogenic factors, and offspring birthweight z score in women with type 1 diabetes. Methods: This cohort study included samples from 157 Continuous Glucose Monitoring in Pregnant Women with Type 1 Diabetes (CONCEPTT) trial participants. Correlations were estimated between birthweight z score and placental growth factor (PlGF) and soluble fms-like tyrosine kinase (sFlt-1) levels measured at baseline and at 24 and 34 weeks of gestation. Linear regression was used to assess the relationship between birthweight z score and placental health, as measured by PlGF and sFlt-1/PlGF ratio, stratified by glycaemic status (continuous glucose monitoring and HbA1c measures) and adjusted for potential confounders of maternal BMI, smoking and weight gain. Higher PlGF levels and lower sFlt-1/PlGF ratios represent healthy placentas, while lower PlGF levels and higher sFlt-1/PlGF ratios represent unhealthy placentas. Results: Among CONCEPTT participants, the slopes relating PlGF levels to birthweight z scores differed according to maternal glycaemia at 34 weeks of gestation (p = 0.003). With optimal maternal glycaemia (HbA1c < 48 mmol/mol [6.5%]/ or continuous glucose monitoring time above range ≤ 30%), birthweight z scores were reduced towards zero (normal weight) with increasing PlGF values (representing a healthy placenta), and increased with decreasing PlGF values. With suboptimal glycaemic status (HbA1c ≥ 48 mmol/mol [6.5%] or time above range > 30%), increasing PlGF values were associated with heavier infants. Those with a healthy placenta (PlGF > 100) and suboptimal glycaemic control had a higher mean z score (2.45) than those with an unhealthy placenta (mean z score = 1.86). Similar relationships were seen when using sFlt-1/PlGF ratio as a marker for a healthy vs unhealthy placenta. Conclusions/interpretation: In women with type 1 diabetes, infant birthweight is influenced by both glycaemic status and placental function. In women with suboptimal glycaemia, infant birthweight was heavier when placentas were healthy. Suboptimal placental function should be considered in the setting of suboptimal glycaemia and apparently 'normal' birthweight. [ABSTRACT FROM AUTHOR]

Results Case 1 presented at 4-weeks gestation in her second pregnancy, having had a previous miscarriage at 7-weeks gestation. They encompass improvements in our understanding of continuous glucose monitoring (CGM) in pregnancy, early data on the first commercially available closed-loop system used (off-license) during pregnancy, and advancements in our understanding of screening for GDM. As CGM in pregnancy continues to gain more widespread use, identifying these patterns using FDA may not only aid in the understanding of the pathophysiology of various glycemic-related complications but also help diabetes clinicians and women with diabetes identify and target patterns to reduce adverse outcomes. The manuscripts chosen for this year's article on technology and pregnancy demonstrated advances in our understanding of type 1, type 2, and gestational diabetes (GDM) in pregnant women.

The article focuses on the good news for pregnant women with type 1 diabetes and past or current gestational diabetes. Topics discussed include the National Institute for Health and Care Excellence (NICE) reviewed the evidence and updated their recommendations on intermittently scanned and Continuous Glucose Monitoring (CGM) during pregnancy for type 1 diabetes women; and the NICE guidelines recommend offering CGM to all pregnant women with type 1 diabetes.

In recent years, continuous glucose monitoring (CGM) has become increasingly available with the introduction of devices that are specifically approved for use during pregnancy. Evidence in the form of randomized-controlled trials and cohort studies continues to build support for the use of CGM during pregnancy to improve measures of maternal glycemia as well as obstetric and neonatal outcomes. Based on data from the CGM in pregnant women with type 1 diabetes (CONCEPTT) trial alongside a Swedish cohort study of real-world outcomes of pregnant women with type 1 diabetes, the UK National Institute for Health and Clinical Excellence (NICE) guidelines now recommend that real-time CGM be offered to all pregnant women with type 1 diabetes. Based on these guidelines, all pregnant individuals in the United Kingdom with type 1 diabetes will receive government-funded real-time CGM for a 12-month duration. These guidelines are a game-changer and will continue to facilitate more widespread access to CGM use in the United Kingdom and beyond. This review describes the role of CGM in the management of diabetes in pregnancy, discusses contemporary maternal glucose levels and their relationship with outcomes in diabetes pregnancies, and examines the high-quality, randomized-controlled trial and the real-world clinical data evaluating the impact of CGM use.

The manuscripts chosen for this year's technology and pregnancy article provide new insights into fetal exposure to maternal glucose during pregnancies complicated by gestational diabetes, and type 1 diabetes. Data relating continuous glucose monitoring (CGM) in type 1 diabetes pregnancy to neonatal outcomes are scarce. Healthcare providers and women with diabetes can focus on increasing CGM time in range during the latter half of pregnancy to reduce the risk of neonatal hypoglycemia. Women with gestational diabetes were more likely to develop type 2 diabetes or prediabetes than women without gestational diabetes (adjusted OR 3.44 [95% CI 2.84, 4.14]).

The article discusses research which described longitudinal continuous glucose monitoring (CGM) metrics during healthy pregnancy and following Roux-en-Y gastric bypass (RYGB) in women aged 29 years. The study measured mean CGM glucose levels during the day and overnight throughout pregnancy, glycemic variability, median nocturnal CGM glucose in Bariatric Surgery and Consequences for Mother and Baby in Pregnancy (BAMBI) control participants, target glucose range, and pregnancy outcomes.

Aims/hypothesis: We performed a systematic review and meta-analysis to determine whether exposure to maternal pre-existing diabetes in pregnancy is associated with neurocognitive or behavioural outcomes in offspring. Methods: We searched MEDLINE, EMBASE, PsychINFO, the Cochrane Database of Systematic Reviews and Scopus for studies that examined any neurocognitive or behavioural outcomes in offspring of mothers with pre-existing diabetes in pregnancy in accordance with a published protocol (PROSPERO CRD42018109038). Title and abstract review, full-text review and data extraction were performed independently and in duplicate. Risk of bias was assessed using the Newcastle–Ottawa scale. Meta-analyses of summary measures were performed using random-effects models. Results: Nineteen articles including at least 18,681 exposed and 2,856,688 control participants were identified for inclusion. Exposure to maternal pre-existing diabetes in pregnancy was associated with a lower pooled intelligence quotient in the offspring (pooled weighted mean difference −3.07 [95% CI −4.59, −1.55]; I2 = 0%) and an increased risk of autism spectrum disorders (effect estimate 1.98 [95% CI 1.46, 2.68]; I2 = 0%). There was also an increased risk of attention deficit/hyperactivity disorder (pooled HR 1.36 [95% CI 1.19, 1.55]; I2 = 0%), though this was based on only two studies. Although most studies were found to be high quality in terms of participant selection, in many studies, comparability of cohorts and adequacy of follow-up were sources of bias. Conclusions/interpretation: There is evidence to suggest that in utero exposure to maternal pre-existing diabetes is associated with some adverse neurocognitive and behavioural outcomes. It remains unclear what the role of perinatal factors is and the degree to which other environmental factors contribute to these findings. [ABSTRACT FROM AUTHOR]

Objective: To compare glycemic control, quality of life, and pregnancy outcomes of women using insulin pumps and multiple daily injection therapy (MDI) during the Continuous Glucose Monitoring in Women With Type 1 Diabetes in Pregnancy Trial (CONCEPTT).Research Design and Methods: This was a prespecified analysis of CONCEPTT involving 248 pregnant women from 31 centers. Randomization was stratified for pump versus MDI and HbA1c. The primary outcome was change in HbA1c from randomization to 34 weeks' gestation. Key secondary outcomes were continuous glucose monitoring (CGM) measures, maternal-infant health, and patient-reported outcomes.Results: At baseline, pump users were more often in stable relationships (P = 0.003), more likely to take preconception vitamins (P = 0.03), and less likely to smoke (P = 0.02). Pump and MDI users had comparable first-trimester glycemia: HbA1c 6.84 ± 0.71 vs. 6.95 ± 0.58% (51 ± 7.8 vs. 52 ± 6.3 mmol/mol) (P = 0.31) and CGM time in target (51 ± 14 vs. 50 ± 13%) (P = 0.40). At 34 weeks, MDI users had a greater decrease in HbA1c (-0.55 ± 0.59 vs. -0.32 ± 0.65%, P = 0.001). At 24 and 34 weeks, MDI users were more likely to achieve target HbA1c (P = 0.009 and P = 0.001, respectively). Pump users had more hypertensive disorders (P = 0.011), mainly driven by increased gestational hypertension (14.4 vs. 5.2%; P = 0.025), and more neonatal hypoglycemia (31.8 vs. 19.1%, P = 0.05) and neonatal intensive care unit (NICU) admissions >24 h (44.5 vs. 29.6%; P = 0.02). Pump users had a larger reduction in hypoglycemia-related anxiety (P = 0.05) but greater decline in health/well-being (P = 0.02).Conclusions: In CONCEPTT, MDI users were more likely to have better glycemic outcomes and less likely to have gestational hypertension, neonatal hypoglycemia, and NICU admissions than pump users. These data suggest that implementation of insulin pump therapy is potentially suboptimal during pregnancy. [ABSTRACT FROM AUTHOR]

Objective: Despite advances in technology, optimal glucose control remains elusive and neonatal complications remain ubiquitous in type 1 diabetes (T1D) pregnancy. Our aim was to examine the safety, efficacy, and longer-term feasibility of day-and-night closed-loop insulin delivery.Research Design and Methods: We recruited 16 pregnant women (mean [SD]: age 32.8 [5.0] years, T1D duration 19.4 [10.2] years, HbA1c 8.0% [1.1], and BMI 26.6 [4.4] kg/m2) to an open-label, randomized, crossover trial. Participants completed 28 days of closed-loop and sensor-augmented pump (SAP) insulin delivery separated by a washout period. Afterward, participants could continue to use the closed-loop system up to 6 weeks postpartum. The primary end point was the proportion of time with glucose levels within the target range (63-140 mg/dL).Results: The proportion of time with glucose levels within target was comparable during closed-loop and SAP insulin delivery (62.3 vs. 60.1% [95% CI -4.1 to 8.3]; P = 0.47). Mean glucose and time spent hyperglycemic >140 mg/dL also did not differ (131.4 vs. 131.4 mg/dL [P = 0.85] and 36.6 vs. 36.1% [P = 0.86], respectively). During closed-loop, fewer hypoglycemic episodes occurred (median 8 [range 1-17] vs. 12.5 [1-53] over 28 days; P = 0.04) and less time at <63 mg/dL (1.6 vs. 2.7%; P = 0.02). Hypoglycemia <50 mg/dL (0.24 vs. 0.47%; P = 0.03) and low blood glucose index (1.0 vs. 1.4; P = 0.01) were lower. Less nocturnal hypoglycemia (2300-0700 h) during closed-loop therapy (1.1 vs. 2.7%; P = 0.008) and a trend toward higher overnight time in target (67.7 vs. 60.6%; P = 0.06) were found.Conclusions: Closed-loop insulin delivery was associated with comparable glucose control and significantly less hypoglycemia than SAP therapy. Larger, longer-duration multicenter trials are now indicated to determine clinical efficacy of closed-loop insulin delivery in T1D pregnancy and the impact on neonatal outcomes.

Gestational diabetes mellitus (GDM) is defined as hyperglycaemia that is diagnosed for the first time in the second or third trimester of pregnancy. It occurs in one in seven pregnancies worldwide and is associated with increased risk of adverse perinatal outcome, in particular, infant birth weight that is large for gestational age, increased infant adiposity, preeclampsia and preterm delivery, and increased delivery by caesarean section. This review focuses on the controversy regarding screening and diagnosis of GDM following development of the International Association of Diabetes and Pregnancy Study Groups (IADPSG) guidelines and the National Institute of Clinical Excellence (NICE) 2015 guidelines. It reviews the most recent research in to diet and exercise modification in prevention and management of GDM, pharmacological management and post-partum management to delay and/or prevent progression to type 2 diabetes.

Background: Women with type 1 diabetes strive for optimal glycemic control before and during pregnancy to avoid adverse obstetric and perinatal outcomes. For most women, optimal glycemic control is challenging to achieve and maintain. The aim of this study is to determine whether the use of real-time continuous glucose monitoring (RT-CGM) will improve glycemic control in women with type 1 diabetes who are pregnant or planning pregnancy.Methods/design: A multi-center, open label, randomized, controlled trial of women with type 1 diabetes who are either planning pregnancy with an HbA1c of 7.0 % to ≤10.0 % (53 to ≤ 86 mmol/mol) or are in early pregnancy (<13 weeks 6 days) with an HbA1c of 6.5 % to ≤10.0 % (48 to ≤ 86 mmol/mol). Participants will be randomized to either RT-CGM alongside conventional intermittent home glucose monitoring (HGM), or HGM alone. Eligible women will wear a CGM which does not display the glucose result for 6 days during the run-in phase. To be eligible for randomization, a minimum of 4 HGM measurements per day and a minimum of 96 hours total with 24 hours overnight (11 pm-7 am) of CGM glucose values are required. Those meeting these criteria are randomized to RT- CGM or HGM. A total of 324 women will be recruited (110 planning pregnancy, 214 pregnant). This takes into account 15 and 20 % attrition rates for the planning pregnancy and pregnant cohorts and will detect a clinically relevant 0.5 % difference between groups at 90 % power with 5 % significance. Randomization will stratify for type of insulin treatment (pump or multiple daily injections) and baseline HbA1c. Analyses will be performed according to intention to treat. The primary outcome is the change in glycemic control as measured by HbA1c from baseline to 24 weeks or conception in women planning pregnancy, and from baseline to 34 weeks gestation during pregnancy. Secondary outcomes include maternal hypoglycemia, CGM time in, above and below target (3.5-7.8 mmol/l), glucose variability measures, maternal and neonatal outcomes.Discussion: This will be the first international multicenter randomized controlled trial to evaluate the impact of RT- CGM before and during pregnancy in women with type 1 diabetes.Trial Registration: ClinicalTrials.gov Identifier: NCT01788527 Registration Date: December 19, 2012.

OBJECTIVE -- To implement and evaluate a regional prepregnancy care program in women with type 1 and type 2 diabetes. RESEARCH DESIGN AND METHODS -- Prepregnancy care was promoted among patients and health professionals and delivered across 10 regional maternity units. A prospective cohort study of 680 pregnancies in women with type 1 and type 2 diabetes was performed. Primary outcomes were adverse pregnancy outcome (congenital malformation, stillbirth, or neonatal death), congenital malformation, and indicators of pregnancy preparation (5 mg folic acid, gestational age, and A1C). Comparisons were made with a historical cohort (n = 613 pregnancies) from the same units during 1999-2004. RESULTS -- A total of 181 (27%) women attended, and 499 women (73%) did not attend prepregnancy care. Women with prepregnancy care presented earlier (6.7 vs. 7.7 weeks; P < 0.001), were more likely to take 5 mg preconception folic acid (88.2 vs. 26.7%; P < 0.0001) and had lower A1C levels (A1C 6.9 vs. 7.6%; P < 0.0001). They had fewer adverse pregnancy outcomes (1.3 vs. 7.8%; P < 0.009). Multivariate logistic regression confirmed that in addition to glycemic control, lack of prepregnancy care was independently associated with adverse outcome (odds ratio 0.2 [95% CI 0.05-0.89]; P = 0.03). Compared with 1999-2004, folic acid supplementation increased (40.7 vs. 32.5%; P = 0.006) and congenital malformations decreased (4.3 vs. 7.3%; P = 0.04). CONCLUSIONS -- Regional prepregnancy care was associated with improved pregnancy preparation and reduced risk of adverse pregnancy outcome in type 1 and type 2 diabetes. Prepregnancy care had benefits beyond improved glycemic control and was a stronger predictor of pregnancy outcome than maternal obesity, ethnicity, or social disadvantage. [ABSTRACT FROM AUTHOR]

A gap currently exists between our expectations of tight blood glucose control and the reality of safely achieving it before and during pregnancy. Technological and pharmaceutical advances will not in isolation prevent poor pregnancy outcomes without recognising the social, cultural and behavioural context of the women living with diabetes. Neither will behavioural and/or educational programmes completely overcome the fundamentally disordered metabolic pathways and physiological challenges of pregnancy. Improved integration of the technological, behavioural and educational aspects of diabetes care will pave the way for truly personalized, interdisciplinary diabetes management and ultimately improved pregnancy outcomes for women with diabetes and their infants. [ABSTRACT FROM AUTHOR]

The pregnancy outcomes for women with type 1 diabetes remain poor with increased risk of major congenital malformation, stillbirth, premature delivery and perinatal death compared to the background maternity population. Despite clear evidence that women who attend prepregnancy care have improved blood glucose control with reduced risk of serious adverse outcomes, only a minority of women attend these clinics. For women with type 2 diabetes who are older, more obese and more likely to belong to an ethnic minority or live in an area of social deprivation, pregnancy outcomes are at least as poor as for women with type 1 diabetes. This is important as the prevalence of type 2 diabetes in women of reproductive years is increasing and even fewer women with type 2 diabetes attend prepregnancy care or take folic acid supplementation. Greater awareness regarding the risks among women with diabetes as well as primary and secondary healthcare professionals is required, if pregnancy outcomes are to be improved.

The authors present a response to a comment on the study regarding use of insulin pump or multiple daily injections in type 1 diabetes (T1D) pregnancy glycemic outcomes. The authors agree that more data are needed regarding the optimal implementation of insulin pump therapy during T1D. However, owing to some psycho social complexity, the authors claim that it is not practical to collect detailed data on patient-clinician relationship regarding insulin pump usage.

Gestational diabetes mellitus (GDM) annually affects 35,000 pregnancies in the United Kingdom, causing suboptimal health outcomes to the mother and child. Obesity and excessive gestational weight gain are risk factors for GDM. The Institute of Medicine recommends weight targets for women that are overweight and obese, however, there are no clear guidelines for women with GDM. Observational data suggest that modest weight loss (0.6–2 kg) after 28 weeks may reduce risk of caesarean section, large-for-gestational-age (LGA), and maternal postnatal glycaemia. This protocol for a multicentre randomised double-blind controlled trial aims to identify if a fully controlled reduced energy diet in GDM pregnancy improves infant birthweight and reduces maternal weight gain (primary outcomes). A total of 500 women with GDM (National Institute of Health and Care Excellence (NICE) 2015 criteria) and body mass index (BMI) ≥25 kg/m2 will be randomised to receive a standard (2000 kcal/day) or reduced energy (1200 kcal/day) diet box containing all meals and snacks from 28 weeks to delivery. Women and caregivers will be blinded to the allocations. Food diaries, continuous glucose monitoring, and anthropometry will measure dietary compliance, glucose levels, and weight changes. Women will receive standard antenatal GDM management (insulin/metformin) according to NICE guidelines. The secondary endpoints include caesarean section rates, LGA, and maternal postnatal glucose concentrations. [ABSTRACT FROM AUTHOR]

In this article, the author talks about the healthcare outcomes of pregnant women's suffering with type 1 diabetes, using insulin pump therapy which is associated with improved glucose control and discussed cost implications of such women's.
