The Effect of E-Health Management on Gestational Diabetes Control

Study Overview
=================
Brief Summary
-----------------
The purpose of this study was to develop an e-heath management platform(eHMP) for women with high risk of gestational diabetes mellitus (GDM) and to evaluate the longitudinal effects between groups of eHMP intervention.

Detailed Description
-----------------
Background: Women with previous gestational diabetes mellitus are at increased risk for developing type2 diabetes mellitus or metabolic syndrome in their later life. Infants of mothers with GDM are more susceptible to stillbirth and more serious health concerns. With limited time for visits and the predicament of education, applying web-based intervention has become a convenient tool for health management. Objectives: The approved project aimed to develop an e-heath management platform(eHMP) for women with high risk of gestational diabetes mellitus (GDM) and to evaluate the longitudinal effects between groups of eHMP intervention. The eHMP integrate GDM health care knowledge, self-awareness of health, self-monitoring of health status (i.e., recording weight and measurement data of metabolic syndrome risk factors and monitoring changes in data trends); participation in discussions or browsing forums; healthy lifestyle guidance and counseling; reminder systems, a token system of earning points in exchange for prizes. Methods: Pregnant women aged 18-45 years with high risk of metabolic syndrome who have a singleton pregnancy, are eligible to participate in this study. Women who agree to participate in the study will be given a participant information sheet and consent form. Participants will be recruited from the Pregnancy diabetes Clinic, at Chang Gung memorial hospital and introduced to the eHMP using the mobile phone in the clinic. Participants will also be given the URL to access to the program and they can learn the modules at home by using their home PCs, mobile phones, or tablets. They were followed up for three times: 28 weeks' gestation, 36-40 weeks' gestation and 6-12 weeks postpartum. SPSS version 20.0 software was used to compile and analyze the research data, including questionnaires and blood test for metabolic index.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of Triglyceride Level | Blood sampling was performed in the fasting state. Normal triglyceride was <150 mg/dl; ≥150mg/dl was abnormal | Change from Baseline at 6-12 weeks after delivery | 
| Change of Fasting Blood Glucose (FBG) Level | Blood sampling was performed in the fasting state. Normal FBG was < 100 mg/dl; ≥100mg/dl was abnormal | Change from Baseline at 6-12 weeks after delivery | 
| Change of high-density lipoprotein cholesterol (HDL) level | Blood sampling was performed in the fasting state. Normal HDL was ≥50 mg/dl; <50mg/dl was abnormal | Change from Baseline at 6-12 weeks after delivery | 
| Change of Cholesterol level | Blood sampling was performed in the fasting state. Normal Cholesterol was < 200 mg/dl; ≥200mg/dl was abnormal | Change from Baseline at 6-12 weeks after delivery | 
| Change of systolic blood pressure | Normal systolic blood pressure was <130mmHg; ≥130mmHg was abnormal. Blood pressure was measured at the right arm twice after a 10-min rest in the supine position by using a calibrated sphygmomanometer and averaged. | Change from Baseline at 6-12 weeks after delivery | 
| Change of diastolic blood pressure | Normal diastolic blood pressure was <85mmHg; ≥85mmHg was abnormal. Blood pressure was measured at the right arm twice after a 10-min rest in the supine position by using a calibrated sphygmomanometer and averaged. | Change from Baseline at 6-12 weeks after delivery | 
| Change of body weight | Women's weight following as assessed using calibrated digital scales | Change from Baseline at 6-12 weeks after delivery | 
| Newborn baby weight | Newborn baby weight in normal range (>2500g - <4500g) - dichotomous outcome Yes/No assessed using calibrated digital scales. | at birth | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of Pregnancy Physical Activity Assessment | There are 12 items in this questionnaire, including two dimensions: exercise and inactivity. Exercise dimension contained four items to assess the type of physical activity, intensity, duration, frequency during pregnancy. At least 3 days per week, and each time at least 20-30 minutes, counted as regular exercise (dichotomous outcome Yes/No assessed). Inactivity dimension contained 8 items, dichotomous outcome Yes/No assessed (score 0-8), higher values represent an inactivity lifestyle. | Change from Baseline at 6-12 weeks after delivery | 
| Change of Dietary Behavioral Characteristics Scale | The instrument is 17-item Likert-type self-report instrument, used a 5-point response format to obtain data regarding the frequency of reported behaviors (never, rarely, sometimes, usually, always). It including two dimensions and each scale range as: balanced diet (5 items, scale range 5-25) and diet control behavior (12 items, scale range 12-60). Higher values represent a better maternal dietary patterns during pregnancy. | Change from Baseline at 6-12 weeks after delivery | 
| Change of Health Promotion Scale | The instrument is 40-item Likert-type self-report instrument, used a 5-point response format to obtain data regarding the frequency of reported behaviors (never, rarely, sometimes, usually, always). It including six dimensions and each scale range as: social-support (6 items, scale range 6-30), life-appreciation (8 items, scale range 8-40), health-responsibility (8 items, scale range 8-40), stress-management (9 items, scale range 9-45), nutritional behaviors (5 items, scale range 5-25) and exercise behaviors (4 items, scale range 4-20). The total score was 40 to 200, higher values represent a better health promotion lifestyle. | Change from Baseline at 6-12 weeks after delivery |
