Diabetes Prevention for Black Men

Not Applicable

Terminated

Brief Summary: 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.

Recruitment & Eligibility

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

Arm && Interventions

Group	Intervention	Description
Dietary intervention	Dietary intervention	Community-based dietary intervention to Black and African American barbers identified as having previously undiagnosed diabetes and prediabetes

Primary Outcome Measures

Name	Time	Method
Continuation with the dietary intervention after initial period when study participants may choose to pay for meals developed on their own	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.
Adherence to the intervention during the initial 60-day period when lunches are provided at no cost	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.

Secondary Outcome Measures

Name	Time	Method
First Point-of-care Hemoglobin A1c (HbA1c) test	Baseline	This first baseline point-of-care HbA1c test will be used as a reference.
Fourth Point-of-Care HbA1c Test	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
Photographic food and beverage diaries	Baseline	Study participants will take photos of all food and beverages ingested over a 72-hourperiod to provide quantitative data on baseline dietary patterns
Second Point-of-care HbA1C test	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.
Third Point-of-care HbA1C test	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
