Not Applicable

Completed

• Conditions: Prediabetes
• Interventions: Behavioral: Blood Test Group Intervention; Behavioral: Brochure Group Intervention

• Registration Number: NCT02747108
• Lead Sponsor: VA Office of Research and Development

Brief Summary

This study will evaluate the effects of screening for type 2 diabetes mellitus (T2DM) and brief counseling about screening test results on weight and key health behaviors among Veterans with risk factors for T2DM. Study participants will be randomly assigned to one of two study groups: (1) Blood Test Group or (2) Brochure Group. Participants in the Blood Test Group will complete a blood test called hemoglobin A1c (HbA1c) which measures average blood sugar levels. Participants will receive brief counseling about the results from their primary care provider or someone authorized to speak on their behalf. Participants randomly selected for the Brochure Group will review a handout from the VA National Center for Health Promotion and Disease Prevention (NCP) on recommended screening tests and immunizations. All participants will be asked to complete a survey prior to study group assignment, immediately after a Primary Care appointment, 3 months after enrollment, and 12 months after enrollment.

Detailed Description

An essential step in designing effective strategies to improve patient engagement in behavior change is to better understand their current levels of engagement in these behaviors and determine which factors most influence their engagement. Within and outside the Veterans Health Administration (VHA), little is known about how patients with risk factors for T2DM view their risk of developing T2DM, what these patients understand about strategies to reduce this risk, and to what degree at-risk patients are currently engaging in behaviors to prevent T2DM. This project will generate important new data in these areas and will improve the investigators' understanding of the effects of a prediabetes diagnosis and brief counseling on engagement in behaviors to prevent T2DM and mediators of these behaviors.

Arm && Interventions

Group	Intervention	Description
Blood Test Group	Blood Test Group Intervention	Patients will complete an HbA1c test and then receive brief counseling and written information about their test result based on the American Diabetes Association and National Diabetes Prevention Program guidelines.
Brochure Group (usual care)	Brochure Group Intervention	Patients will not complete an HbA1c test and will instead receive brief counseling and written information about recommended screenings and immunizations.

Primary Outcome Measures

Name	Time	Method
Weight Change From Baseline to 12 Months	12 months	The primary outcome will be weight change 12 months after an HbA1c test and brief counseling or review of health promotion literature.

Secondary Outcome Measures

Name	Time	Method
Change in Use of Medication for T2DM Prevention	3 and 12 months	The investigators will use medical record data and survey data to evaluate changes in use of medication for T2DM prevention after an HbA1c test and brief counseling or review of health promotion literature.
Changes in Participation in a Weight Management Program	3 months and 12 months	The investigators will use survey data to evaluate changes in participation in a weight management program after an HbA1c test and brief counseling or review of health promotion literature.
Changes in Knowledge of Strategies to Prevent T2DM	2 weeks, 3 months, and 12 months	The investigators will use survey data to evaluate changes in knowledge of strategies to prevent T2DM after an HbA1c test and brief counseling or review of health promotion literature. Respondents were given 3 open-ended questions to report things they could do to prevent T2DM. Each respective response to the 3 questions were coded and scored according to whether they indicated engagement in the following activities: weight loss, physical activity, use of metformin, or enrollment into a diabetes prevention program. Each question denoted with a positive response were coded with 1 whereas those that did not were coded as a 0. The three questions were summed into a final score ranging from 0 (no report of engagement in the aforementioned healthy activities) with the worst outcome to 3 (a report of 3 of the 4 aforementioned healthy activities) with the best outcome.
Changes in Perception for Risk for T2DM	Baseline, 2 weeks, 3 months, and 12 months	The investigators will use survey data to evaluate changes in perception of risk for T2DM after an HbA1c test and brief counseling or review of health promotion literature. The Adriaanse T2DM Risk Perception Scale, which was included in the survey, measured self-assessed risk perception from 0 denoting no choice of developing T2DM to 100 denoting absolute confidence in developing T2DM.
Changes in Motivation to Prevent T2DM	Baseline, 2 weeks, 3 months, and 12 months	The investigators will use survey data to evaluate changes in motivation to prevent T2DM after an HbA1c test and brief counseling or review of health promotion literature. The Treatment Self-Regulation Questionnaire (TSRQ) was included in the survey and respondents were asked about their level of motivation from 1 (Not at all motivated) to 10 (Highly motivated).
Changes in Self-efficacy to Engage in Behaviors to Prevent T2DM	Baseline, 3 months and 12 months	The investigators will use survey data to evaluate changes in self-efficacy to engage in behaviors to prevent T2DM after an HbA1c test and brief counseling or review of health promotion literature. The Perceived Competence Scale was used to measure respondent self-efficacy from 1 (lowest) to 7 (highest).
Change in Physical Activity	Baseline, 3 months and 12 months	The investigators will use survey data to evaluate changes in physical activity after an HbA1c test and brief counseling or review of health promotion literature. The International Physical Activity Questionnaire - Short Form (IPAQ-SF) was used to measure physical activity change. Respondents were asked to report how many hours and minutes within the past week they completed of vigorous physical activity, moderate physical activity, and brisk walking. The total sum of minutes for these three questions were subsequently coded into a yes/no binary variable for whether respondents met a recommended 150 minutes of overall physical activity within 7 days of being assessed. The values provided reflect a proportion of respondents that met or exceeded the 150 minute threshold of overall physical activity based on the newly generated variable that combined total minutes of vigorous physical activity, moderate physical activity, and brisk walking.
Change in Mental Health	Baseline, 2 weeks, 3 months, and 12 months	The investigators will use survey data to evaluate changes in SF-12 mental health scores after an HbA1c test and brief counseling or review of health promotion literature. The SF-12 provides a calculation of (1) a physical score (PCS-12) generated from a subset of questions focused on physical health and (2) a mental health score (MCS-12) generated from a subset of questions focused on mental health. The data provided represent the mean score of the PCS-12 and MCS-12. Scores range from 0 to 100, where a zero score indicates the lowest level of physical/mental health measured by the scales and 100 indicates the highest level of physical/mental health.
