What is being measured
The primary outcome is the main question the study is designed to answer.
Effectiveness of mHealth apps at changing bodyweight assessed by bodyweight measurements over 6 months
Determine if the mhealth app is an effective weight loss modality compared to standard weight loss program (control)
Outcome measure will be body weight in kg
Measured: 3 months
Self-efficacy in weight management assessed by Weight Management and Nutrition Knowledge questionnaire
Compare and determine which intervention promotes self-efficacy in weight management.
Reporting will be on a scale of 0-100, with higher scores indicating higher self-efficacy
Measured: 3 months
Long-term change in diabetes via fasting blood glucose
Compare and determine which intervention elicits the most change towards diabetes via fasting blood glucose
Outcome measure will be fasting blood glucose
Measured: 3 months
Quality of Life after using mHealth apps assessed by World Health Organization Quality of Life BREF questionnaire
Comparing the two arms to determine which leads to greater quality of life (QOL)
Measures will be reported on a scale of 1-5 across four domains. Scores will be converted to a scale of 0-100
Measured: 3 months
