Text Based Mobile Technology and Weight Loss

Completed · Not applicable

Conditions studied: Obesity

In brief

Hispanic populations in the US are dis-proportionally affected by high rates of obesity and diabetes; according to the Centers for Disease Control and Prevention, Latinos are the minority group with the second-highest obesity prevalence in adults. In comparison to the general female population (61.2%), Mexican American women (73%) have a greater overweight or obese percentage. In addition, more than 50% of Hispanic men and women are expected to develop type-2 diabetes over their lifetime, compared to 40% among whites. Hispanics are also 50% more likely to die from diabetes compared to whites. In many cases Hispanic populations do not have the knowledge, self-confidence and resources to participate in mainstream physical activity and nutrition interventions, which are usually geared towards the general population without considering cultural and linguistic differences. Information and communication technologies in the form of Internet and mobile phone access have grown enormously during the past decade; these technologies have the potential to affect food intake and physical activity as well as weight loss. Approximately 95% of countries have mobile telephone networks and about 70% of people worldwide use mobile phones. CareMessage is a Google-backed 501(c)3 nonprofit technology organization based in San Francisco that uses 'smart' text and voice messaging to enable clinical staff to provide automated yet personalized support to patients struggling with chronic conditions. The CareMessage™ Adult Obesity texting program adapts the Health Belief Model by strategically implementing behavioral concepts to help improve self-efficacy. The investigators will pilot test its effectiveness among a sample of Hispanic women who are at risk of obesity and diabetes by sending a culturally-sensitive and linguistically-appropriate text-based message three to 5 times a week, encouraging lifestyle modifications (diet and exercise education and behavior modification).
