Clinical Trial Summary
In an effort to personalize medical care, novel approaches have been used to categorize
sub-populations of patients with type 2 diabetes (T2D). These are based on biological and
genetic variables, allowing identification of clusters with significantly different clinical
characteristics and risks of complications that may be more amenable to targeted and precise
therapeutic interventions. Increasingly, wearable and other digital health technologies have
the potential to capture additional and objective information to support personalized
medicine but at present underserved populations have largely been excluded from clinical
trials incorporating digital health.
With this study, the Investigators aim to build on prior work using specially trained
community health workers ("Community Scientists") to support engagement with an underserved
population and to encourage adherence to using wearables and other digital health
technologies. In the US, this is especially imperative for the Hispanic/Latino population,
which is at high risk for T2D and associated complications.
Description:
As treatment choices for type 2 diabetes (T2D) evolve from a one-size-fits-all approach into
a patient-centered precision medicine model, there is a need for a deeper understanding of
the clinically meaningful differences between individuals to inform therapy choice.
Recently there have been new approaches to creating sub-groups of populations with T2D based
on biological, psychosocial, and genetic variables which have identified clusters of patients
with significantly different clinical characteristics and risk of associated complications.
By incorporating personal, wearable digital health technologies, it will become possible to
further refine such stratification through the inclusion of additional variables and advances
in big data analytics and machine learning. The vision is that identifying sub-groups at high
risk of complications early in the course of T2D will help clinicians to offer more effective
personalized therapies.
In the US, the prevalence of both diagnosed and undiagnosed T2D is nearly twice as high among
Mexican-origin Hispanic/Latino adults compared to non-Hispanic whites. Rates of
diabetes-related complications are also higher among Hispanic/Latino adults. T2D is also
associated with a high burden of depression. There are independent barriers to the treatment
of depression in the Hispanic/Latino population, and a population with comorbid depression
and T2D could represent a distinct endophenotype requiring modified treatment plans that
address common pathophysiological pathways linking both diseases. Of particular interest is
the common presence of anxiety symptoms that can worsen depression prognosis and muddle the
diagnostic picture. For this purpose, and to elucidate better endophenotypes in our study,
attention will be paid to anxious distress, a specifier of major depressive disorder that
could potentially be very pertinent to this population, and bring about somatic complaints,
insomnia, and irritability.
Although wearable technologies for self-monitoring such as continuous glucose monitors (CGM)
are used in diabetes care, the overwhelming experience has been in type 1 diabetes and
insulin-treated type 2 diabetes. There is much less use in individuals with non-insulin
treated T2D or those at risk of diabetes. Across all forms of diabetes, minority use of CGM
has been consistently and markedly less than in the general population with diabetes.
Diet plays a crucial role in the management of T2D. To design personalized dietary
recommendations, it is vital to understand an individual's food behaviors. Mobile health
platforms present the opportunity to collect detailed information regarding daily food
choices. In this study, data collected through daily food logging and ecological momentary
assessment (EMA) on hunger, satisfaction, and satiety will be used to quantify and understand
the individual's dietary behaviors and glycemic outcomes.
To summarize the rationale behind this study, developments in precision medicine have allowed
for the categorization of individuals with T2D into sub-groups that may be amenable to
different therapeutic strategies. However, there is also a need to better understand the
impact of behavioral and psychological factors on the risk of progression of T2D and
responses to existing and new therapies, especially in the context of development of
depressive symptomatology. These may be especially relevant for US minorities, such as
Hispanic/Latino adults who have an excess burden of T2D and the associated complications
compared to non-Hispanic whites. Digital health has the potential to be of enormous value
provided it is acceptable and will be used by underserved communities.
