Background: Early-onset GDM often requires pharmacological treatment and is associated with adverse perinatal outcomes, but data is insufficient regarding the best methods to identify high-risk women requiring early GDM screening. The aim of this study was to analyze the diagnostic accuracy of HbA1c in the prediction of (1) plasma glucose concentrations > 90th percentile in an oral glucose tolerance test (OGTT) at 12–16 weeks' gestation; and (2) pharmacologically treated early- or late-onset GDM. Methods: HbA1c was measured at 8—14 weeks' gestation in a population-based cohort of 1394 Finnish women recruited for the Early Diagnosis of Diabetes in Pregnancy (EDDIE) study between 3/2013 and 12/2016. Information on maternal risk factors were collected at recruitment. Subsequently, a 2-hour 75 g OGTT was performed at 12—16 weeks' gestation (OGTT1), and if normal, repeated at 24–28 weeks' gestation (OGTT2). Early- and late-onset GDM were diagnosed using the same nationally endorsed cut-offs for fasting, 1 h- and 2 h-plasma glucose: ≥5.3, ≥ 10.0mmol/l, and/or ≥ 8.6mmol/l, respectively. In total, 52/1394 (3.7%) women required metformin or insulin treatment for GDM, including 39 women with early-onset GDM diagnosed at OGTT1 and 13 women with late-onset GDM diagnosed at OGTT2. Results: Maternal early-pregnancy HbA1c ≥ 35mmol/mol (≥ 5.4%) was the best cut-off to predict fasting or post-load plasma glucose > 90th percentile in OGTT1, but its diagnostic accuracy was low [AUC (95% CI) 0.65 (0.62 to 0.69), sensitivity 0.55 (0.49 to 0.60) and specificity 0.67 (0.64 to 0.70)] both alone and in combination with other maternal risk factors. However, HbA1c ≥ 35mmol/mol correlated positively with plasma glucose concentrations at all time points of OGTT1 and predicted pharmacologically treated GDM diagnosed at OGTT1 or OGTT2; AUC (95% CI) 0.75 (0.68 to 0.81), sensitivity 0.75 (0.61 to 0.86), specificity 0.64 (0.61 to 0.66). Conclusions: In our population-based cohort, early-pregnancy HbA1c ≥ 35mmol/mol was positively associated with fasting and post-load plasma glucose concentrations in an OGTT at 12—16 weeks' gestation and predicted pharmacologically-treated early- and late-onset GDM, suggesting potential utility in first-trimester identification of women at high risk of severe GDM subtypes.

Obesity increases the risk of low 25-hydroxyvitamin D (25(OH)D) concentrations and gestational diabetes (GDM). We explored whether the association between GDM and change in 25(OH)D concentrations measured in the first (7-18 wk) and second (20-27 wk) trimesters of pregnancy is dependent on maternal BMI. The study was a prospective study of 219 women with BMI of [greater than or equal to]30 kg/m.sup.2, a history of GDM, or both. The participants were stratified by first-trimester BMI: BMI of, Author(s): Anita J Valkama [sup.1] [sup.2] , Jelena M Meinilä [sup.1] , Saila B Koivusalo [sup.3] , Jaana Lindström [sup.4] , Kristiina Rönö [sup.3] , Aila E Tiitinen [sup.3] , [...]

Objectives To assess the associations of perceived financial satisfaction and health-related quality of life (HRQoL) and depressive symptoms in an unselected pregnant population in early pregnancy. Methods 750 consecutive pregnant women attending the first communal ultrasound examination before gestational week 14 were invited to participate. Questionnaires assessing HRQoL (15D), depressive symptoms (Edinburgh Depression Scale, EPDS), medical, obstetric, and socioeconomic status were handed out. The participants were divided into three groups according to their satisfaction with their financial status, (unsatisfied, somewhat satisfied, and satisfied). Main outcome measures were 15D and EPDS-scores and dimensions of HRQoL. Results 325 (43,3%) questionnaires were returned. The mean 15D-score for HRQoL was 0,926 (SD 0,056). The financially unsatisfied women had lower HRQoL than women in more satisfied groups (0.906, 0.923 and 0.931, p = 0.012). The result remained significant, even after adjusting for age and education(p = 0.032). The unsatisfied women had a higher mean body mass index (BMI) (25.4, 24.4 and 23.2 kg/m.sup.2, p for linearity = 0.002), were more often smokers, (13 vs. 4 and 3%, p = 0.029), and had experienced at least one abortion (18, 14 and 7%, p = 0.017). Dimensions of depression, distress and sleep explained the differences between the groups. 27% of unsatisfied women scored EPDS [greater than or equal to]10 points suggesting increased risk of depression. Conclusions Financial satisfaction in early pregnancy associates with HRQoL and risk of perinatal depressive symptoms. Unsatisfied women more often have risk factors for unfavourable pregnancy outcomes which may influence the later health and wellbeing of the mother and child., Author(s): Niina Sahrakorpi [sup.1] [sup.7] , Saila B.

Background The incidence of gestational diabetes (GDM) is increasing and interventions to curb the detrimental effects of GDM are needed. We have previously reported that a combined diet and physical activity intervention has the potential to reduce GDM among high-risk women. It is also important to know whether the intervention affects health-related quality of life (HRQoL). Methods A total of 378 women at high risk for GDM were randomized into an intervention (lifestyle counselling four times during pregnancy, n =192), or a control group (n =186) before 20 gestational weeks. HRQoL was assessed with the 15D-instrument six times: once during each trimester and at six weeks, six months and 12 months postpartum. Results In this study population, the cumulative incidence of GDM was similar in the intervention and the control group (45.7 vs. 44.5%). There was no difference between the 15D scores of the control and intervention groups at any of the time points. Conclusions Combined diet and physical activity intervention did not provide HRQoL benefits in the study. A high prevalence of GDM in both study groups may have confounded the effect of the intervention. [ABSTRACT FROM AUTHOR]

Purpose: Lifestyle intervention studies performed during pregnancy have shown inconsistent results in relation to prevention of gestational diabetes mellitus (GDM). Therefore, the aim of this study was to assess the effect of an intervention initiated already before pregnancy in prevention of GDM in high-risk women.Patients and methods: A randomized controlled trial was conducted in four Finnish maternity hospitals between the years 2008 and 2014. Altogether 228 high-risk women planning pregnancy were randomized to an intervention (n=116) or a control group (n=112). The risk factors were body mass index ≥30 kg/m2 (n=46), prior GDM (n=120), or both (n=62), without manifest diabetes at study inclusion. Trained study nurses provided individualized lifestyle counseling every 3 months in addition to a group session with a dietician. The control group received standard antenatal care. GDM was defined as one or more pathological glucose values in a 75 g 2-hour oral glucose tolerance test, performed between 12 and 16 weeks of gestation and if normal repeated between 24 and 28 weeks of gestation.Results: Within 12 months, 67% of the women (n=72) in the intervention group and 63% of the women (n=71) in the control group (p=0.84) became pregnant. The cumulative incidence of GDM among the women available for the final analyses was 60% (n=39/65) in the intervention group and 54% (n=34/63) in the control group (p=0.49). GDM was diagnosed already before 20 weeks of gestation in 60% (n=44/73) of the cases.Conclusion: The preconceptional lifestyle intervention applied in the present study did not reduce the incidence of GDM.

Introduction: The purpose was to examine the effects of a randomized lifestyle intervention on self-rated health from pregnancy to postpartum in participants at high risk for gestational diabetes mellitus.Methods: We included 266 women with a history of gestational diabetes and/or prepregnancy BMI ≥30 kg/m2. The intervention group (n = 144) received individualized counseling on diet, physical activity, and weight management from trained nurses at six timepoints between the first trimester of pregnancy and 12 months postpartum, and met three times with a dietitian. The control group (n = 122) received standard antenatal care. We assessed self-rated health at the six timepoints by means of a single question with five response options ranging from good (1) to poor (5). Baseline-adjusted mean changes in self-rated health level were assessed with a mixed model for repeated measure methods.Results: The mean (SD) for self-rated health at baseline was 1.8 (0.8) in the intervention group and 2.1 (0.9) in the control group (p = 0.006). Self-rated health varied over time (time effect p < 0.001) and was the poorest in the third trimester. The sample indicated that self-rated health improved in the intervention group and deteriorated in the control group from the first trimester to 12 months postpartum, but the difference between the groups did not reach statistical significance (group effect p = 0.064).Discussion: The self-rated health level varied over time from the first trimester of pregnancy to 12 months postpartum in women at risk for gestational diabetes. Improving self-rated health among high-risk pregnant women through lifestyle intervention calls for further research. [ABSTRACT FROM AUTHOR]
