The purpose of this study is to determine the effectiveness of mobile health applications in improving health outcomes and the subsequent benefit of improving type II diabetes outcomes in a low socioeconomic Hispanic population.
View original scientific description
The purpose of this study is to determine the effectiveness of mobile health applications in improving health outcomes and the subsequent benefit of improving type II diabetes outcomes in a low socioeconomic Hispanic population. 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.
Interventions
OTHER
Mobile health application
Intervention will be with two different mobile health (mHealth) applications, Weight Watchers and Healthi app (formerly iTrackBites)
Primary outcome measures
Effectiveness of mHealth apps at reducing bodyweight assessed by bodyweight measurements over 6 months
Time frame: 6 months
Determine if mHealth apps-Weight Watchers (WW) and Healthi app-are an effective weight loss modality compared to standard weight loss program (control)
Most effect intervention for weight loss in first 3 months
Time frame: 6 months
Compare the three interventions, mHealth apps and control, against each other to determine which is most effective at achieving the maximum amount of weight loss within the first three months
Most effective intervention for weight loss by 6 months
Time frame: 6 months
Compare and determine which intervention leads to the highest weight loss maintenance after six months
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
Long term diabetes improvement via A1c
Time frame: 6 months
Compare and determine which intervention provides the best improvements towards diabetes via blood glucose and HbA1c

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
