Efficacy of Using Mobile Health Applications for Health

The purpose of this study is to determine the effectiveness of mobile health applications in improving health outcomes and type II diabetes outcomes in type 2 diabetics. This study will involve a 6-month long commitment where participants will be expected to weigh themselves every morning, at the same time, and check their blood glucose readings daily before and after meals for at least three meals in the day.

Intervention will be with mobile health application

Primary outcomes

  1. Effectiveness of mHealth apps at changing bodyweight assessed by bodyweight measurements over 6 months

    Time frame: 6 months

    Determine if mhealth app is an effective weight loss modality compared to standard weight loss program (control)

    Outcome measure will be body weight in kg

  2. Self-efficacy in weight management assessed by Weight Management and Nutrition Knowledge questionnaire

    Time frame: 6 months

    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

  3. Long term change in diabetes via A1c

    Time frame: 6 months

    Compare and determine which intervention elicits the most change towards diabetes via HbA1c

    Outcome measure will be HbA1c

  4. Long term change in diabetes via fasting blood glucose

    Time frame: 6 months

    Compare and determine which intervention elicits the most change towards diabetes via fasting blood glucose

    Outcome measure will be fasting blood glucose

Secondary outcomes

  1. Quality of Life after using mHealth apps assessed by World Health Organization Quality of Life BREF questionnaire

    Time frame: 6 months

    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
