Food Assistance, Diabetes, and HIV

Recruiting

• Conditions: HIV/AIDS; FOOD SECURITY; Diabetes
• Interventions: Other: Food assistance

• Registration Number: NCT04045184
• Lead Sponsor: University of Alabama at Birmingham

Brief Summary

Diabetes prevalence is increasing among people living with HIV (PLWH), yet blood glucose control is less successful in this population who are also often food insecure. Food assistance programs often provide nutrient-poor foods. This proposal asses the feasibility of monitoring diabetes-related health outcomes among food insecure PLWH who are receiving food boxes higher in dietary protein and fiber and lower in simple carbohydrates.

Detailed Description

The objective of this investigation is to develop and assess a study protocol to evaluate the impact of food assistance on diabetes-related health outcomes in food insecure people living with HIV (PLWH). Compared to the general population, PLWH have increased risk for type 2 diabetes and worse glycemic control when using similar pharmaceutical treatments. Interventions to improve diet quality could thus have a clinically meaningful impact on diabetes treatment in this population. However, many PLWH are food insecure and rely on food assistance to meet basic nutrition needs. This proposal will determine the feasibility of a protocol to evaluate diabetes-related health outcomes in food insecure PLWH and diabetes who receive high protein, high dietary fiber food boxes from Birmingham AIDS Outreach. The study will consist of retrospective analysis of electronic medical record data and stored specimens, and prospective cross-sectional analysis of food security and diet quality in PLWH who do versus those who do not receive the food boxes.

Specific Aim 1: To determine the feasibility of recruiting, enrolling, and collecting dietary intake data from people living with HIV who are food insecure.

Specific Aim 2: To compare changes over twelve months in glycemic control, food security, and diet quality in B-FED participants compared to non-participating 1917 clinic patients.

This proposal aligns with the UAB Diabetes Research Center's goal to facilitate development of new methods to treat diabetes and its complications. The investigators will determine the effect size for scale-up of larger, longer-term assessment through an NIDDK-R18 grant to evaluate the real-world impact of B-FED on glycemic control and food security.

Arm && Interventions

Group	Intervention	Description
B-FED	Food assistance	Clients of the Birmingham AIDS Outreach Food and Education Delivery (B-FED) program who are also patients at the 1917 Clinic.

Primary Outcome Measures

Name	Time	Method
To determine the feasibility of recruiting, enrolling from people living with HIV who are food insecure.	1 year	We will track the ability to recruit and enroll eligible participants in the study.
To determine the feasibility of collecting dietary intake data from people living with HIV who are food insecure.	1 year	We will track the percentage of enrolled participants who complete 3 24-hour diet recalls
Change in diabetes-related health outcomes as measured by hemoglobin A1c.	1 year	Six months after program enrollment, B-FED participants will have improved glycemic control (lower hemoglobin A1c). Value will be measured using stored blood samples.
Change in diabetes-related health outcomes as measured by body weight.	1 year	Six months after program enrollment, B-FED participants will have improved body mass index (calculated using height and weight from electronic medical record) versus PLWH with insulin resistance and type 2 diabetes who do not participate in the program. Body weight will be measured to the nearest 0.1 kg using a Medtronic scale. Height will be measured to the nearest 0.1 cm using a stadiometer. The values will be used to compute the body mass index (weight\[kg\]/height\[m2\]).
Change in diabetes-related health outcomes as measured by waist circumference	1 year	Six months after program enrollment, B-FED participants will have lower waist circumference versus PLWH with insulin resistance and type 2 diabetes who do not participate in the program. Waist circumference will be measured to the nearest 0.1 cm using a flexible measuring tape.
Compare food security among groups using the Food Security Questionnaire.	1 year	B-FED participants will report a higher prevalence of food security compared to clinic patients who do not participate in the program. This will be assessed at 1 time point using the validated 2-item Food Security Questionnaire to classify participants as food secure, low food security, or very low food security.
Compare hemoglobin A1c levels between groups with high versus low dietary fiber intake	1 year	B-FED participants in the highest tertile of dietary fiber intake will experience greater reductions in hemoglobin A1c levels compared to participants in the lowest fiber tertile. Hemoglobin A1c will be measured using stored blood samples. Dietary fiber intake will be assessed as the average daily fiber intake in grams from three 24-hour diet recalls.
