Filter by:The IBEP study is a randomized control trial of a healthy lifestyle intervention program for women with gestational diabetes. The primary aim of the study is to evaluate whether women with gestational diabetes enrolled in an intensive behavioral educational program (IBEP) demonstrate lower mean fasting glucose levels measured by 2 hour 75 gram oral glucose tolerance test (OGTT) at 6 weeks postpartum compared to women with gestational diabetes who undergo routine gestational diabetes education and counseling.
Gestational diabetes, diabetes diagnosed during pregnancy, affects 8.8% of pregnancies in Spain that means more than 40,000 women per year. This prevalence is based on the National Diabetes Data Group criteria, previous to the 4th workshop on Gestational Diabetes (1998), but, if the new diagnosis criteria proposed by the International Associations of Diabetes and Pregnancy Study Groups, based on the most important study never made before on this topic, prevalence would increase to the double. When a women is diagnosed, the risk of complications for her and the child increases and, therefore, she has to start an specific diet and frequent visits to the diabetes center in order to check that glucose values do not exceed 95 mg/dl before or 140 mg/dl 1-hour after meals. In other case, she should start insulin treatment. Our project is aimed to develop intelligent tools based on neuro-diffuse techniques and integrated in a telemedicine system that allows control of gestational diabetes automatically, guaranteeing glucose control objectives consecution and avoiding face-to-face visits to the health care center. Furthermore, educational and motivation tools for a healthy behaviour will be included. At the end of the study efficacy and security about insulin management will be compare with the recommendations proposed by the diabetes team and data about direct and indirect costs will be calculated. The investigators anticipate that the smart telemedicine system can allow us to detect high blood glucose values earlier than in-person scheduled visits.
The main objective of the study is to estimate and compare the percentage of patients with abnormal glucose metabolism at 4-12 weeks postpartum between two groups: patients diagnosed with gestational diabetes before or after 24 weeks of pregnancy. Abnormal glucose metabolism is defined as type 2 diabetes, glucose intolerance or impaired fasting glucose.
The incidence of gestational diabetes mellitus (GDM) is increasing. GDM requires patients to test their blood glucose at least four times daily. The investigators propose to prospectively evaluate blood glucose testing done every day compared to every other day. The primary goal is to establish the most cost-effective modality while still being able to detect patients who require therapy in a timely fashion. The investigators plan to evaluate this new management scheme utilizing a non-inferiority trial design. The investigators primary research question is the following: When managing patients with GDM, is every other day blood glucose testing non-inferior compared to every day blood glucose testing, as measured by the difference of less than 5% in birth weight?
The purpose of this study is to determine whether a 14 week intervention is successful in improving outcomes for women with gestational diabetes mellitus and their infants.
The purpose of this study are: - Assess the impact of an intervention to the adoption of healthy lifestyles among pregnant women at high risk of gestational diabetes mellitus on: - weight gain in pregnancy - the levels of maternal and fetal adipokines and - glycemic control maternal and fetal. - Determine whether the adoption of healthy lifestyles in pregnancy is associated with epigenetic changes that influence the levels of adipokines and glucose regulation during pregnancy and in newborns.
Personal behaviors can influence development of Gestational Diabetes Mellitus (GDM), a condition that can adversely affect the pregnant woman, her developing fetus and future events for both. To reduce GDM risk, we will develop and implement an in-person team and web-based nutrition and exercise program for women, beginning in their first trimester. A scripted, peer-led, 20-week educational program, tailored for pregnant women working in teams (5 women/team), will be developed and implemented among pregnant employees and/or their spouses. Each weekly thirty minute session will focus on achieving 30-minutes of moderate daily physical activity with nutrition targets of five servings of fruits and vegetables, 3 servings of whole grains and lower fat food choices. Diet, exercise and lab assessments will occur before enrollment during the first trimester, each subsequent trimester and 12 weeks after delivery. In addition to exercise and diet survey results, we will assess fasting glucose, insulin, hemoglobin A1C levels, pregnancy weight gain, blood pressure, lipid and lipoprotein levels, pedometer records, weekly accelerometer data, each trimester and at 12 weeks post delivery, as well as gestational birth age, Apgar score, delivery mode and infant birth weight, and weekly health thermometer self-ratings during the assessment period.
The objective of the study is to investigate the effect of stress on glucose tolerance during pregnancy. The main objectives of the study are to investigate if various measures of stress (stressful life events, the perceived level of stress and the cortisol or copeptin concentrations) differ between pregnant women with and without gestational diabetes during the end of the second/beginning of the third trimester when presenting for their routine glucose tolerance testing. Secondary objectives are the link between these different stress measures and the routinely measured fasting and stimulated glucose levels during the oral glucose tolerance test.
OVERALL OBJECTIVES: 1. To assess the efficacy of a diet and exercise intervention before and/or during pregnancy in the prevention of GDM and its fetal complications in women with high diabetes risk. 2. To assess the cost-effectiveness of a diet and exercise intervention in the prevention of GDM from a socio-economic point of view. To find out whether the intervention can be used to reduce health care costs due to GDM and T2DM. 3. To determine the long-term effectiveness of the above-mentioned lifestyle intervention in the reduction of T2DM incidence among women with prior GDM and their offspring STUDY SUBJECTS Group 1: Women planning pregnancy with a history of diet/insulin-treated GDM or BMI >30 kg/m2. N= 250 + 250. Group 2: Women in early pregnancy with a history of diet/insulin-treated GDM or BMI >30 kg/m2. N= 250 + 250 METHOD The Finnish multi-center randomized controlled intervention trial started in the maternity hospitals of Helsinki and Uusimaa District Area 1/2008 and in the South-Karelia Central Hospital in Lappeenranta in 9/2008. 1000 women at high GDM risk will be recruited. Half of the subjects are randomized into the intervention group and the other half act as controls receiving only standard antenatal care in addition to the laboratory tests taken and questionnaires administered by the RADIEL study. The active intervention arm of the study will be carried out in a structured, standardized manner by diabetes nurses and nutritionists specifically trained for their tasks. The intervention includes: 1. Structured visits to diabetes nurse every 3 months before and during pregnancy as well as at 6 weeks, 6 and 12 months post partum. Visits include e.g. structured counseling on diet and exercise, setting of specific goals, follow-up of achievements, laboratory tests and measurements 2. Structured group visits to nutritionist at the moment of enrollment in the study, at the beginning of pregnancy as well as at 6 and 12 months post partum. Additional individual visits are booked if needed. 3. Services of physical activity advisors are provided by the study subjects' cities of residence free of charge to all who wish to receive extra counseling on exercise. If exercise goals are not met, study subjects book an appointment with the physical activity advisor.

Intervention will continue until 2014 (including pre- and postpartum periods). Long-term follow up of both mothers' and children's cohorts starts in 2014 and has been planned to continue up to 10 years postpartum. Data analysis starts in autumn of 2013 and results will be reported from 2014 onwards in international peer-reviewed journals.
Childhood obesity is a critical global public health concern. Breastfeeding is the ideal choice for infant nutrition. However, rapid and excess weight gain during infancy predicts later, even among breastfed infants. This risk is higher if mothers are obese and/or diabetic. Composition of bioactive components of breast milk may differ based between mothers who are normal weight (NW), overweight, or who have diabetes. Obesity and Type 2 Diabetes are associated with overall increases in inflammation and oxidative stress, but how breast milk composition is affected remains unknown. The investigators overarching goal is to determine how maternal obesity and Type 2 Diabetes impacts human breast milk composition and how differences in composition may impact infant growth and fat development. The investigators are undertaking a study that follows 20 Normal Weight, 20 Obese, 20 Gestational Diabetic, and 20 Type 2 Diabetic mothers and their infants over the first 4 months of life. The investigators will track infant weight and fat gain and monitor maternal glucose control. The investigators will also collect breast milk samples over the first 4 months and measure concentrations of growth and appetite hormones, cytokines, markers of oxidative stress and nutrient composition in milk. The investigators predict that concentrations of growth-regulatory hormones (insulin and leptin) in addition to the inflammatory cytokines and markers of oxidative stress will be lowest in breast milk from NW mothers, higher in breast milk from obese and gestational diabetic mothers, and highest in Type 2 Diabetic mothers' breast milk. The investigators expect these differences will be most pronounced in the first 2 weeks after birth. The investigators also predict that breast milk concentrations of these biomarkers will be associated with infant fat gain. What the investigators find will help understand how early infant nutrition and growth may affect that child's later risk of obesity.
