The incidence of obstructive sleep apnea (OSA) is higher in pregnancy than in non-pregnancy,and obesity is a major risk factor.OSA in pregnancy can lead to multiple organ dysfunction and is associated with hypertensive disorders in pregnancy,gestational diabetes mellitus,premature birth,and fetal growth restriction. Therefore,early screening and diagnosis are essential for the prevention and treatment of OSA in pregnancy.

Gestational diabetes mellitus(GDM)can cause blood glucose disorders in pregnant women and result in adverse maternal-neonatal outcomes.Vitamin D(VD)can improve glucose tolerance and insulin sensitivity,and thus theoretically,VD supplementation during pregnancy could improve glycemic control as well as maternal-neonatal outcomes in GDM patients.Although studies have shown that VD deficiency is associated with poor maternal-neonatal outcomes in GDM patients,no solid conclusion has been drawn with regard to the effects of VD supplementation on these patients.Therefore,here we summarized the research progress of the effects of VD supplementation on glycemic control and adverse maternal-neonatal outcomes in GDM patients,in an effort to guide the clinical VD supplementation during pregnancy.

gestational diabetes mellitus (GDM) has been increasing worldwide, as has the economic cost associated with this condition. GDM threatens the health of the mother and child, and thus proper monitoring and management are essential. Mobile healthcare services have been applied to manage some diseases, particularly chronic diseases. We aimed to evaluate the utility of a mobile application in nutritional intervention by observing cases of a mobile application in a series of patients with GDM. We provided a mobile-based intervention to GDM patients and collected biochemical and nutritional information. The mobile-based nutritional intervention was effective in controlling carbohydrate intake and improving blood glucose level for patients with GDM.]]>

BACKGROUND: An early identification of the risk groups might be beneficial in reducing morbidities in patients with gestational diabetes mellitus (GDM). Therefore, this study aimed to assess the biochemical predictors of glycemic conditions, in addition to fasting indices of glucose disposal, to predict the development of GDM in later stage and the need of glucose-lowering medication.METHODS: A total of 574 pregnant females (103 with GDM and 471 with normal glucose tolerance [NGT]) were included. A metabolic characterization was performed before 15+6 weeks of gestation by assessing fasting plasma glucose (FPG), fasting insulin (FI), fasting C-peptide (FCP), and glycosylated hemoglobin (HbA1c). Thereafter, the patients were followed-up until the delivery.RESULTS: Females with NGT had lower levels of FPG, FI, FCP, or HbA1c at the early stage of pregnancy, and therefore, showed an improved insulin action as compared to that in females who developed GDM. Higher fasting levels of FPG and FCP were associated with a higher risk of developing GDM. Moreover, the predictive accuracy of this metabolic profiling was also good to distinguish the patients who required glucose-lowering medications. Indices of glucose disposal based on C-peptide improved the predictive accuracy compared to that based on insulin. A modified quantitative insulin sensitivity check index (QUICKIc) showed the best differentiation in terms of predicting GDM (area under the receiver operating characteristics curve [ROC-AUC], 72.1%) or need for pharmacotherapy (ROC-AUC, 83.7%).CONCLUSION: Fasting measurements of glucose and C-peptide as well as the surrogate indices of glycemic condition could be used for stratifying pregnant females with higher risk of GDM at the beginning of pregnancy.

OBJECTIVES: The aim of this study was to examine self-management status, nutritional knowledge, barrier factors in dietary management and needs of nutritional management program for women with Gestational Diabetes Mellitus (GDM). METHODS: A total of 100 women with GDM were recruited from secondary and tertiary hospitals in Seoul. The questionnaire composed of general characteristics, status of self-management, dietary habits, nutrition knowledge, barrier factors in dietary management, needs for nutrition information contents and nutritional management programs. Data were collected by a self-administered questionnaire. All data were statistically analyzed using student's t-test and chi-square test using SAS 9.3. RESULTS: About 35% of the subjects reported that they practiced medical nutrition and exercise therapy for GDM control. The main sources of nutrition information were ‘internet (50.0%)’ and ‘expert advice (45.0%)’. More than 70% of the subjects experienced nutrition education. The mean score of nutrition knowledge was 7.5 point out of 10, and only about half of the subjects were reported to be correctly aware of some questions such as ‘the cause of ketosis’, ‘the goal of nutrition management for GDM’, ‘the importance of sugar restriction on breakfast’. The major obstructive factors in dietary management were ‘eating more than planned when dining out’, ‘finding the appropriate menu when dining out’. The preferred nutrition information contents in developing management program were ‘nutritional information of food’, ‘recommended food by major nutrients’, ‘the relationship between blood glucose and food’, ‘tips on menu selection at eating out’. The subjects reported that they need management program such as ‘example of menu by calorie prescription’, ‘recommended weight gain guide’, ‘meal recording and dietary assessment’, ‘expert recommendation’, ‘sharing know-how’. CONCLUSIONS: Based on the results of this study, it is necessary to develop a program that provide personalized information by identifying the individual characteristics of the subjects and expert feedback function through various information and nutrition information contents that can be used in real life.

Gestational diabetes mellitus (GDM) is commonly defined a frequent metabolic condition associated with pregnancy that leads to substantial maternal and perinatal complications. Medical nutrition therapy (MNT) is the cornerstone treatment on patients with GDM, and accordingly, it has a significant impact in women and newborns. The main purpose of MNT in GDM is carbohydrates because they are the major nutrient affecting postprandial euglycemia. Recent epidemiological studies suggest that low-carbohydrate intake is related to beneficial effects on maternal and newborn outcomes. Current evidence consistently supports the advantages of using the glycemic index for additional benefit. Therefore in this context, we will discuss from summarize studies involving carbohydrate in GDM. In addition, this article describes the efficacy of low glycemic index diet for the management of GDM.

Gestational diabetes mellitus (GDM) is one of the most common medical complications during pregnancy. Both mother and baby are at increased risk of adverse pregnancy outcomes, as well as long-term metabolic effects such as diabetes. Diagnosing and treating GDM can reduce perinatal complications. The International Association of Diabetes and Pregnancy Study Groups (IADPSG) has proposed a new screening strategy for overt diabetes at the first prenatal visit and diagnostic criteria for GDM based on perinatal outcomes. However, controversies still exist and there is no international consensus about these issues. Regarding the management of GDM, individualized medical nutrition therapy is the cornerstone of treatment. If maternal glucose levels and/or fetal growth patterns show a sufficiently high risk of perinatal complications, insulin can be used to intensify treatment, and regimens should be tailored to meet glycemic targets. Postpartum screening for early detection of glucose intolerance and implementation of diabetes prevention programs are important for women with a history of GDM.

PURPOSE: The purpose of this study was to investigate the effects of using a Coaching Program on Comprehensive Lifestyle Modification with pregnant women who have gestational diabetes. METHODS: The research design for this study was a non-equivalent control group quasi-experimental study. Pregnant women with gestational diabetes were recruited from D women's hospital located in Gyeonggi Province from April to October, 2013. Participants in this study were 34 for the control group and 34 for the experimental group. The experimental group participated in the Coaching Program on Comprehensive Lifestyle Modification. The program consisted of education, small group coaching and telephone coaching over 4weeks. Statistical analysis was performed using the SPSS 21.0 program. RESULTS: There were significant improvements in self-care behavior, and decreases in depression, fasting blood sugar and HbA1C in the experimental group compared to the control group. However, no significant differences were found between the two groups for knowledge of gestational diabetes mellitus. CONCLUSION: The Coaching Program on Comprehensive Lifestyle Modification used in this study was found to be effective in improving self-care behavior and reducing depression, fasting blood sugar and HbA1C, and is recommended for use in clinical practice as an effective nursing intervention for pregnant women with gestational diabetes.
