Diabetes Prevention for Black Men

June 10, 2021 updated by: NYU Langone Health

Using a Geographically Targeted and Mixed Methods Approach to Improve Glycemic Control Among Black Men Identified as Having Previously Undiagnosed Diabetes and Prediabetes

Geographic analyses of diabetes burden have found that poor glycemic control, high rates of diabetes-related hospital utilization, and a high prevalence of microvascular diabetic complications all cluster in the same neighborhoods.This proposed study seeks to identify Black barbers with undiagnosed diabetes or prediabetes using point-of-care HbA1c testing, perform qualitative interviews to identify health behaviors that may explain poor sugar control, and develop a workplace-based food intervention to promote primary prevention and test its effect on sugar control in these individuals.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
16

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Black or African American men who work as barbers at Black-owned barbershops
  • Barbershop clients.
  • Workplace in neighborhood geographically identified as having higher diabetes burden
  • No prior history of clinical diagnosis of diabetes
  • Identified on initial and second point-of-care testing to have an HbA1c of 5.7 or greater

Exclusion Criteria:

  • Individuals with a history of blood loss or blood disorder that would lead to incorrect results on point-of care HbA1c testing
  • Individuals with a history of food allergies that requires specific dietary restrictions
  • Individuals who are not English speaking
  • Individuals who have a significant cognitive impairment that will be a barrier to communication, valid consent and participation

Design Details

  • Primary Purpose: Prevention
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Dietary intervention
Community-based dietary intervention to Black and African American barbers identified as having previously undiagnosed diabetes and prediabetes
Behavioral: Dietary intervention
Over a 60-day period, participants will receive healthy lunches that provide a hand-delivered healthy alterative to their current diets.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adherence to the intervention during the initial 60-day period when lunches are provided at no cost
Time Frame: 60 days
Adherence will be calculated as the proportion of participants continuing to consume at least 80% of the lunch meals at the end of the initial intervention period when lunches will be provided at no cost.
60 days
Continuation with the dietary intervention after initial period when study participants may choose to pay for meals developed on their own
Time Frame: Until the end of the two year study period
proportion of participants continue to purchase meals after the initial intervention period when individuals will be given the option to continue the intervention but paying for the lunch meals themselves.
Until the end of the two year study period

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Photographic food and beverage diaries
Time Frame: Baseline
Study participants will take photos of all food and beverages ingested over a 72-hourperiod to provide quantitative data on baseline dietary patterns
Baseline
First Point-of-care Hemoglobin A1c (HbA1c) test
Time Frame: Baseline
This first baseline point-of-care HbA1c test will be used as a reference.
Baseline
Second Point-of-care HbA1C test
Time Frame: Baseline (3-6 months after first test)
This second baseline point-of-care HbA1c test will be used to identify any changes in glycemic control that developed after initial diagnosis of diabetes or prediabetes by the first point-of-care test.
Baseline (3-6 months after first test)
Third Point-of-care HbA1C test
Time Frame: Post treatment (3 months after the intervention)
This post-treatment HbA1c test will be used to identify whether there was any short-term change in glycemic control after the dietary intervention
Post treatment (3 months after the intervention)
Fourth Point-of-Care HbA1c Test
Time Frame: Post-Treatment (6 to 12 months after the intervention)
This post-treatment HbA1c test will be used to identify whether there was any longer-term change in glycemic control after the dietary intervention
Post-Treatment (6 to 12 months after the intervention)
