Background: Continuous glucose monitoring (CGM) promotes glycemic benefits in adults with type 2 diabetes (T2D), including insulin users as well as noninsulin users, often with minimal professional support. To investigate whether these benefits may stem from increased user engagement in self-management, we conducted a randomized controlled trial comparing the impact of CGM versus self-monitoring of blood glucose (SMBG) on self-reported engagement and HbA1c in CGM-naïve adults with T2D.

Methods: Potential participants completed the Impact of Glucose Monitoring on Self-Management Scale (IGMSS) and an HbA1c home test to confirm eligibility (>7.

Background: Recent advances in diabetes care and technology, such as real-time continuous glucose monitoring, can help people live more freely, with more flexibility and fewer constraints, thereby enhancing quality of life (QOL). To date, there has been no validated means for measuring this key psychological dimension. We developed the Diabetes Constraints Scale (DCS) to assess perceived constraints pertaining to diabetes self-management.

As diabetes technologies continue to advance, their use is expanding beyond type 1 diabetes to include populations with type 2 diabetes, older adults, pregnant individuals, those with psychiatric conditions, and hospitalized patients. This review examines the psychosocial outcomes of these technologies across these diverse groups, with a focus on treatment satisfaction, quality of life, and self-management behaviors. Despite demonstrated benefits in glycemic outcomes, the adoption and sustained use of these technologies face unique challenges in each population.

Despite the known glycemic benefits of continuous glucose monitoring (CGM) for adults with type 2 diabetes (T2D), the attitudinal and behavioral changes underlying these glycemic improvements remain understudied. This study aimed to qualitatively explore these changes among a sample of adults with T2D. In-depth, semistructured interviews were conducted with adults with T2D who had been using CGM for 3-6 months as part of a larger community project in Ohio.

Although a broad literature on fear of hypoglycemia and its impact on people with type 1 or type 2 diabetes has accumulated over the past three decades, there has been surprisingly little guidance concerning how best to tackle this problem in clinical care. The aim of this article is to begin filling this gap by describing the "hypoglycemic fear syndrome," which we define as hypoglycemic fear that has become so overwhelming that it leads to avoidance behaviors and chronically elevated glucose levels. We begin by presenting several illustrative cases, describing the syndrome and how it is most commonly presented in clinical care, and detailing its most common precipitants.

Background: Continuous subcutaneous insulin infusion (CSII) use in adults with type 1 diabetes offers psychosocial and clinical benefits, but little is known about its impact on such outcomes in the type 2 diabetes (T2D) population. To address this gap, we conducted a quasi-experimental prospective study to assess psychosocial, glycemic, and behavioral changes over six months in T2D adults on multiple daily injections (MDI) who were interested in starting Omnipod DASH, comparing those who did versus did not start on it.

Methods: In total, 458 adults with T2D completed baseline questionnaires assessing psychosocial dimensions (eg, diabetes distress), clinical metrics (eg, HbA [glycosylated hemoglobin]), and behavioral measures (eg, missed mealtime boluses).

The term "prediabetes" has traditionally been used to describe the state of abnormal glucose homeostasis (dysglycemia) that could eventually lead to developing clinical type 2 diabetes. The HbA1c, oral glucose tolerance testing, and fasting glucose measurements represent the standard approaches for assessing risk. However, they do not predict with complete accuracy, nor do they provide individualized risk assessment to determine who will develop diabetes.

The majority of individuals referred to diabetes self-management education and support (DSMES) programs do not access this resource. Of those who do, attrition is high, with anecdotal reports pointing to the didactic and impersonal nature of these programs contributing to low utilization and completion rates. In an effort to develop a more engaging form of DSMES for adults with type 2 diabetes (T2D), we constructed a nondidactic "discovery learning"-based DSMES program centered on real-time flash glucose monitoring (FGM).
