"It feels like medically promoted disordered eating": The psychosocial impact of gestational diabetes mellitus in the perinatal period

Exploring the lived experience of women with gestational diabetes: A cross-sectional Irish national survey

AIM

Gestational diabetes (GDM) poses risks of short- and long-term complications for mother and infant, emphasising the importance of antenatal and postpartum education and support. We aimed to understand the experiences and views of women with GDM in the Republic of Ireland.

METHODS

Women with current or previous GDM were invited to complete an online cross-sectional survey (April-June 2022). Recruitment utilised social media, local media and personal networks. The survey addressed demographics, GDM knowledge and experiences, breastfeeding and weight management during pregnancy and post-pregnancy GDM support needs. Descriptive statistics were conducted, and between-group comparisons were undertaken using the chi-square test. Content analysis was applied to free text data.

RESULTS

Amongst 231 respondents, most were aged 35-39 (42%); 70% experienced a single GDM pregnancy. Only 6% correctly identified their increased level of risk for developing type 2 diabetes. Under half (44.5%) of respondents reported sufficient time with health professionals to address GDM-related questions. Just over half (54.3%) reported attending for diabetes screening at 6-12 weeks postpartum. The majority (66%) expressed a desire for postpartum information, particularly on healthy eating and physical activity. Having a more recent GDM experience was associated with a stronger preference for weaning (p ≤ 0.001) and weight management information (p = 0.025). Qualitative analysis identified inconsistencies in healthcare messaging, significant concerns about a GDM diagnosis' impact on the pregnancy experience, and financial costs of diagnosis.

CONCLUSIONS

The findings underscore women's desire for appropriate information and support during and after pregnancy with GDM. Future interventions should address these needs to effectively promote chronic disease prevention after GDM.

Quality of Life in Women With Gestational Diabetes Mellitus and Treatment Satisfaction Upon Intermittently Scanned Continuous Glucose Monitoring

BACKGROUND

To assess the quality of life (QoL) and treatment satisfaction with intermittently-scanned continuous glucose monitoring (isCGM) in women with gestational diabetes mellitus (GDM).

METHODS

This prospective observational study included 189 women with GDM who completed the Korean version of the Audit of Diabetes-Dependent Quality of Life Questionnaire (K-ADDQoL). Among them, 25 women who utilized isCGM between gestational weeks 30 and 34 completed the Korean version of the Diabetes Treatment Satisfaction Questionnaire change version (K-DTSQc) to evaluate their satisfaction with isCGM during pregnancy.

RESULTS

GDM had a negative impact on the perceived QoL in 89.4% of the women. All 19 domains of the K-ADDQoL were adversely influenced by GDM, with the most significant impact on the freedom to eat (weighted impact score, -6.98 ± 2.49, P < 0.001) and the least impact on the sex life (-0.25 ± 0.80, P = 0.008). Younger women and those treated with insulin perceived themselves as being more affected in their QoL due to GDM. Women perceived to have less effect on their QoL attributed to GDM exhibited higher ΔHbA1c one year after delivery (ΔHbA1c, 0.3 ± 0.4% vs. 0.0 ± 0.4% in less affected vs. more affected women). The utilization of isCGM improved treatment satisfaction (overall satisfaction score, 10.36 ± 9.21, P < 0.001), independent of glycemic control during pregnancy.

CONCLUSION

Although GDM negatively affects the perceived QoL during pregnancy, attentiveness to GDM management may have a positive impact on long-term glycemic control. Moreover, employing isCGM can enhance treatment satisfaction in women with GDM.

From the shadows: A qualitative study of fathers' perspectives and experiences of their partner's gestational diabetes mellitus and its implications

AIMS

Gestational diabetes mellitus (GDM) affects an increasing number of women each year. Research involving partners of women with GDM, such as fathers is limited, however, understanding their perspectives and involvement in GDM management could enhance health outcomes for both women and their families. This study aims to explore the impact and experiences of GDM on fathers in the perinatal period.

METHODS

Qualitative, individual, semi-structured interviews were conducted with individuals whose partners either currently had GDM or had been diagnosed with GDM within the past 3 years. All participants identified as biological fathers. Data were transcribed and analysed using reflexive thematic analysis.

RESULTS

Nine fathers participated in the study. Analysis resulted in four themes that explored fathers' experiences of GDM during the perinatal period: 'navigating a GDM diagnosis', 'partnering in management and health', 'finding a place within the GDM journey' and 'the lasting impact of GDM'.

CONCLUSION

Fathers encountered wide-ranging impacts of their partners' GDM. Fathers provided both practical and emotional support to their partners. Engaging fathers in discussions at diagnosis and in management could facilitate the maintenance of positive health behaviour changes postpartum, potentially reducing the risk of type 2 diabetes for both parents.

Unveiling Gestational Diabetes: An Overview of Pathophysiology and Management

Gestational diabetes mellitus (GDM) is characterized by an inadequate pancreatic β-cell response to pregnancy-induced insulin resistance, resulting in hyperglycemia. The pathophysiology involves reduced incretin hormone secretion and signaling, specifically decreased glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), impairing insulinotropic effects. Pro-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6), impair insulin receptor substrate-1 (IRS-1) phosphorylation, disrupting insulin-mediated glucose uptake. β-cell dysfunction in GDM is associated with decreased pancreatic duodenal homeobox 1 (PDX1) expression, increased endoplasmic reticulum stress markers (CHOP, GRP78), and mitochondrial dysfunction leading to impaired ATP production and reduced glucose-stimulated insulin secretion. Excessive gestational weight gain exacerbates insulin resistance through hyperleptinemia, which downregulates insulin receptor expression via JAK/STAT signaling. Additionally, hypoadiponectinemia decreases AMP-activated protein kinase (AMPK) activation in skeletal muscle, impairing GLUT4 translocation. Placental hormones such as human placental lactogen (hPL) induce lipolysis, increasing circulating free fatty acids which activate protein kinase C, inhibiting insulin signaling. Placental 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) overactivity elevates cortisol levels, which activate glucocorticoid receptors to further reduce insulin sensitivity. GDM diagnostic thresholds (≥92 mg/dL fasting, ≥153 mg/dL post-load) are lower than type 2 diabetes to prevent fetal hyperinsulinemia and macrosomia. Management strategies focus on lifestyle modifications, including dietary carbohydrate restriction and exercise. Pharmacological interventions, such as insulin or metformin, aim to restore AMPK signaling and reduce hepatic glucose output. Emerging therapies, such as glucagon-like peptide-1 receptor (GLP-1R) agonists, show potential in improving glycemic control and reducing inflammation. A mechanistic understanding of GDM pathophysiology is essential for developing targeted therapeutic strategies to prevent both adverse pregnancy outcomes and the progression to overt diabetes in affected women.

Beyond one size fits all: Probing patient choices in gestational diabetes management, from screening to postpartum

During antenatal care, gestational diabetes mellitus (GDM) screening is crucial for early diagnosis and treatment to ameliorate clinical outcomes and limit health care expenses. Dietary management and physical activity are central to GDM treatment, however, adherence is often influenced by personal preferences, socioeconomic barriers, and psychological stress. Pharmacologically, insulin and oral hypoglycemic medications, are the main GDM treatment that can be subject to patients' resistance due to fears of needles and side effects. Metformin is increasingly preferred for its ease of administration and lower cost. In the postpartum stage, regular screening for type 2 diabetes mellitus (T2DM) should always be considered despite the possible limitations that could arise, including communication gaps, lack of long-term focus, and personal barriers. Overall, women with GDM prefer personalized, flexible management plans that consider their lifestyle, support from health care professionals (HCPs), and family involvement. Addressing psychological and socioeconomic barriers through education, counseling, and support networks is crucial for improving adherence and health outcomes. Enhancing patient-centered care and shared decision-making can empower women with GDM to manage their condition effectively and maintain lifestyle changes postpartum. Therefore, this review aimed to assess pregnant women's preferences in GDM management, focusing on screening, dietary recommendations, physical activity, and treatment. Additionally, this review examined GDM care in terms of these patients' quality of life and postpartum experiences.

Women's experience of gestational diabetes and healthcare in southern Sweden - a qualitative study

BACKGROUND

Gestational diabetes is one of the most common pregnancy complications, affecting 14% of all pregnancies globally, and its prevalence is increasing. Gestational diabetes is associated with short and long-term complications for both the mother and their offspring, which are possible to prevent by glycemic control mainly facilitated by healthy lifestyle behaviors. Hence, women diagnosed with gestational diabetes have a significant role in disease management which can be perceived as burdensome. Previous research has well documented the psychological implications of diagnosis in the women and the need for support from healthcare. Despite the global burden of disease associated with gestational diabetes, recent qualitative studies exploring women's experiences are scarce, particularly in Sweden. Thus, highlighting a critical gap in understanding the impact of this condition and the women's experiences of diagnosis and prenatal healthcare, which this study aimed to address.

METHODS

Purposive sampling was used to recruit women with previous gestational diabetes in southern Sweden. Individual interviews were held with 17 participants according to a semi-structured interview guide. The interviews were audio recorded and transcribed verbatim. Data analysis was conducted according to qualitative content analysis.

RESULTS

The analysis generated 10 subcategories, which were grouped into three categories labeled: "experience of diagnosis", "a complex relationship with food" and "experience of prenatal healthcare". One theme emerged: to suddenly become a patient as opposed to an expectant mother. Most women were initially overwhelmed by the diagnosis and its consequences. They felt that healthy eating was important, despite it limiting their everyday lives, which also revealed a complicated relationship with food. Women felt supported during pregnancy but abandoned after labor. They requested additional information and emotional support from healthcare personnel, increased awareness and understanding of the treatment burden of gestational diabetes, improved person-centered care, and collaboration between healthcare providers, particularly to ensure better support in reducing future risk of disease.

CONCLUSIONS

This study provides an understanding of women's experience of gestational diabetes and the care provided in southern Sweden. Their views could improve future care regarding both successful gestational diabetes management and post-pregnancy follow-up to prevent long-term adverse health outcomes.

Associations Between Carbohydrate Intake Behaviours and Glycaemia in Gestational Diabetes: A Prospective Observational Study

Carbohydrate intake (CI) has the largest impact on the short-term glycaemia of all nutrients, yet optimal CI management in gestational diabetes remains unclear.

OBJECTIVE

To examine CI behaviours in individuals with recently diagnosed gestational diabetes and their association with self-monitored blood glucose.

METHODS

Data from 97 individuals were collected using food and blood glucose diaries. CI (including amounts, types, and timing) was manually assessed using 15 g servings over 5-8 days, while a 3-day computerised analysis examined a broader intake of macro- and micronutrients.

RESULTS

Elevated fasting glycaemia (EFG) was associated with lower total CI (Mdn 10.8 vs. 12.5 servings/day, p = 0.006), missed meals (Mdn 1.4 vs. 0.0/week, p = 0.007), missed snacks (Mdn 10.5 vs. 7.5/week, p = 0.038), low-carbohydrate meals (<30 g; Mdn 4.3 vs. 2.0/week, p = 0.004), and a higher proportion of energy intake from fat (Mdn 35% vs. 33%, p = 0.047), as compared with in-target fasting glycaemia. In contrast, elevated postprandial glycaemia (EPG) was not significantly associated with total CI, low-carbohydrate meals (<30 g), low-carbohydrate snacks (<15 g), or high-carbohydrate loads (>50 g). EPG was instead associated with high-glycaemic index meals (Mdn 1.6 vs. 0.9 lunch meals/week, p = 0.026; Mdn 0.9 vs. 0.0 dinner meals/week, p = 0.023); and a lower intake of energy (Mdn 7650 kJ vs. 9070 kJ/day, p = 0.031), protein (Mdn 91 g vs. 109 g/day, p = 0.015), fat (Mdn 61 g vs. 84 g/day, p = 0.003), and multiple micronutrients (p <0.05), as compared with in-target postprandial glycaemia.

CONCLUSIONS

CI profiles differed for individuals with EFG, as compared with EPG, emphasising the need for dietary guidelines tailored for gestational diabetes subtypes. Further interventional studies are needed to explore these findings, particularly the associations between EFG and low CI behaviours.

Risk-Prioritised Versus Universal Medical Nutrition Therapy for Gestational Diabetes: A Retrospective Observational Study

BACKGROUND

The optimal application of medical nutrition therapy (MNT) in treating gestational diabetes remains uncertain. MNT involves individualised nutrition assessment and counselling, which is labour-intensive and is not the sole type of intervention offered by clinical dietitians.

OBJECTIVE

To determine whether pregnancy outcomes differed for individuals with gestational diabetes who were offered MNT on a risk-prioritised (RP) versus universal basis.

METHODS

Observational data from two cohorts of individuals who were offered MNT only if they met the high-risk criteria following general group-based dietary education (RP1, n = 369; RP2, n = 446) were compared with a baseline cohort who were universally offered at least one MNT consultation (UM, n = 649). The RP1 cohort were seen during community-wide COVID-19 restrictions in 2021, while RP2 were seen after restrictions had lifted in 2022. Furthermore, the RP approach primarily utilised telemedicine, while the UM approach was delivered in person.

RESULTS

MNT consultations halved under the RP approach (59 vs. 119 sessions per 100 diagnoses for RP2 vs. UM) and saved more than 20 h of dietitian time per 100 diagnoses (95 vs. 73 h for RP2 vs. UM). No significant increases were observed (p < 0.05) for any pregnancy outcomes in the RP cohorts compared with the UM cohort, including usage of diabetes medications, maternal weight gain below and above target, early deliveries, induced deliveries, emergency caesarean sections, large- and small-for-gestational-age (SGA) infants, infant macrosomia, neonatal hypoglycaemia and neonatal intensive care admissions. The use of both basal insulin (27% vs. 33%, OR 0.62, 95% CI 0.46 to 0.84) and metformin (6% vs. 10%, OR 0.52, 95% CI 0.31 to 0.88) was lower in the RP1 cohort during pandemic restrictions compared with the UM cohort; however, these differences were not retained in the RP2 cohort. Additionally, there were fewer SGA infants under the RP approach, particularly for the RP2 cohort (6% vs. 11% for RP2 vs. UM, OR 0.55, 95% CI 0.34 to 0.89).

CONCLUSIONS

Risk-prioritised MNT was a more efficient dietetic service approach to gestational diabetes than the universal MNT model, with comparable pregnancy outcomes. Similar approaches may represent a strategic way to address sustainable health service planning amidst the rising global prevalence of this condition. However, further research is needed to investigate consumer perspectives, wider service impacts and post-partum maternal and child health outcomes.

Gestational diabetes mellitus and peripartum depression: a longitudinal study of a bidirectional relationship

BACKGROUND

Gestational diabetes mellitus (GDM) and peripartum depression (PPD) are increasing global health issues with potentially long-lasting adverse outcomes. While limited studies suggest a bidirectional relationship between GDM and PPD, most research has been cross-sectional and focused on one direction of the relationship, primarily if GDM predicts postpartum depression. The interplay between antenatal depression and GDM is less explored, with a critical lack of prospective bidirectional studies. This longitudinal study aimed to investigate the bidirectional relationship between GDM and PPD in a total sample and according to different pre-pregnancy body mass index (BMI) categories. Specifically, we examined whether antenatal depression symptoms predict a subsequent GDM diagnosis and whether GDM predicts subsequent postpartum depression symptoms.

METHODS

A three-wave online longitudinal study included 360 women who were followed from the second trimester (20-28 weeks, T1) through the third trimester (32-42 weeks, T2), and into the postpartum period (6-20 weeks after birth, T3). Participants completed the General Data Questionnaire, one item about the diagnosis of GDM, and the Edinburgh Postnatal Depression Scale (EPDS). The sample was stratified according to pre-pregnancy BMI into normal-weight (N = 247) and overweight/obese (N = 113) subgroups. Women with type I and II diabetes, GDM at T1, and underweight BMI were excluded.

RESULTS

In the total sample, antenatal depression symptoms predicted GDM, whereas GDM did not predict postpartum depression symptoms. A bidirectional relationship was observed in normal-weight women, where antenatal depression symptoms predicted subsequent GDM diagnosis, and GDM diagnosis predicted postpartum depression symptoms. In contrast, no associations were found in either direction in the overweight/obese subgroup.

CONCLUSIONS

This study provides evidence of a bidirectional relationship between GDM and PPD only in women with normal body weight before pregnancy. The results highlight the complexity of the relationship between peripartum mental and metabolic health, that is dependent on pre-pregnancy BMI. Clinicians should be aware that normal-weight women may have a unique sensitivity to the bidirectional interplay between GDM and PPD. Pregnant women should be closely monitored for both mental and metabolic health issues and targeted for prevention programs to reduce the risks and burdens associated with both conditions.

Depression, anxiety, and health-related quality of life in normal weight, overweight and obese individuals with diabetes: a representative study in Germany

OBJECTIVE

Diabetes in the course of lifetime is related to a higher risk for mental disorders. The present study addresses the comparison of individuals with diabetes and non-diabetic individuals in depressive symptoms, generalized anxiety symptoms, and health-related quality of life. Furthermore, mediator effect of BMI and health-related quality of life (HRQOL) on the association between diabetes, depression, and generalized anxiety was analyzed.

METHODS

In this cross-sectional study, the three questionnaires PHQ-9, GAD-7, EQ-5D-5L were measured in a representative sample of the German population (N = 2386). In addition, the presence of diabetes and BMI were assessed via self-report.

RESULTS

There were higher values in depressive and anxiety symptoms as well as lower score in HRQOL in individuals with diabetes compared to non-diabetic individuals. Obese individuals with diabetes showed the highest rates in depressive symptoms and generalized anxiety as well as lowest score in HRQOL. With regard to the mediator analyses, association between diabetes, depressive symptoms, and anxiety symptoms is partially mediated by the BMI and fully mediated by the HRQOL.

CONCLUSIONS

In conclusion, individuals with diabetes have an increased risk in the development of depressive and anxiety symptoms as well as lower health-related quality of life. Future research and strategies in the public health policies among individuals with diabetes should take into account that the association between diabetes, depression, and anxiety is mediated by BMI and HRQOL.

Implementation and evaluation of the centering pregnancy group prenatal care model in pregnant women with diabetes: a convergent parallel mixed methods study protocol

BACKGROUND

Diabetes during pregnancy has negative effects on both mothers and their fetuses. To improve perinatal outcomes and women's experience of care, the World Health Organization (WHO) suggests implementing health system interventions to enhance the use and quality of antenatal care. The main goal of this study is to implement and evaluate the outcomes of the Centering Pregnancy group care model for pregnant women with diabetes.

METHODS/DESIGN

The study will consist of three phases: a quantitative phase, a qualitative phase, and a mixed phase. In the quantitative phase, a randomized controlled trial will be conducted on 100 pregnant women with diabetes receiving prenatal care in Tabriz City, Iran. The Summary of Diabetes Self-Care Activities (SDSCA) questionnaire will also be validated in this phase. The qualitative phase will use qualitative content analysis with in-depth and semi-structured individual interviews to explore pregnant women's understanding of the impact of the Centering Pregnancy group care model on their care process. The mixed phase will focus on the degree and extent of convergence between quantitative and qualitative data.

DISCUSSION

The implementation of the Centering Pregnancy group care approach is anticipated to empower women in effectively managing their diabetes during pregnancy, resulting in improved outcomes for both mothers and newborns. Furthermore, adopting this approach has the potential to alleviate the financial burden of diabetes on healthcare system.

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

Background

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.

Methods

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 ≥ 25 kg/m2 or return to prepregnancy weight if prepregnancy BMI < 25 kg/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).

Findings

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.

Interpretation

A blended, mobile-based lifestyle intervention was not effective in achieving weight goals, but reduced the risk to develop metabolic syndrome.

A Critical Review of Diagnostic Strategies and Maternal Offspring Complications in Gestational Diabetes Mellitus

Gestational diabetes mellitus (GDM) is a complex and significant health concern affecting pregnant individuals and their offspring. This review provides a comprehensive examination of GDM, focusing on diagnostic strategies and the associated maternal and offspring complications. We delve into the challenges and controversies surrounding GDM diagnosis, including the variability in diagnostic criteria, diagnostic accuracy and reproducibility issues, ethical considerations, and the influence of ethnicity and genetics. Maternal complications, such as preeclampsia, cesarean sections, long-term health implications, and neonatal complications like macrosomia, hypoglycemia, and respiratory distress syndrome, are explored in detail. Additionally, we investigate the long-term risks of childhood obesity and type 2 diabetes in offspring and potential cognitive and developmental outcomes. This review underscores the critical importance of early detection and effective management of GDM, the need for standardized diagnostic criteria, personalized care plans, and the ongoing pursuit of research to enhance our understanding of this complex condition. GDM remains a dynamic field where ongoing innovation and research promise to improve the health outcomes of pregnant individuals and their children.
