Trial Summary

What is the purpose of this trial?

This trial is testing if delivering healthy food and teaching cooking skills can help adults with high blood pressure and food insecurity. Participants will receive either their regular care or a program that provides food and cooking lessons. The goal is to see if these changes can improve their blood pressure and nutrition.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the FoRKS Program for High Blood Pressure treatment?

Research on culinary medicine and food provision interventions suggests that programs focusing on nutrition education and cooking skills can improve health outcomes by encouraging healthier eating habits. These programs have shown promise in improving diet quality and health markers in conditions like diabetes, which may indirectly support the potential benefits of the FoRKS Program for managing high blood pressure. ^{1 2 3 4 5}

Is the treatment generally safe for humans?

Varenicline, also known as Chantix or Champix, has been associated with some safety concerns, including potential neuropsychiatric symptoms like depression and suicidal thoughts, as well as a small risk of cardiovascular events. However, these risks are generally low, and the overall number of adverse events reported in studies is small. ^{6 7 8 9 10}

How does the FoRKS treatment for high blood pressure differ from other treatments?

The FoRKS treatment is unique because it combines food resources and kitchen skills to help manage high blood pressure, focusing on dietary changes and cooking confidence rather than medication. This approach is different from standard drug treatments, as it emphasizes lifestyle and nutritional education to support health. ^{11 12 13 14 15}

• Food Resources & Kitchen Skills (FoRKS) (Behavioral Intervention)

Trial Overview The study tests a home-delivered foods and kitchen skills program (FoRKS) against Enhanced Usual Care (EUC) to see their effects on blood pressure control, diabetes management (HbA1c), food security, and nutrition in adults with hypertension.

Participant Groups

Group I: Food Resources & Kitchen Skills (FoRKS) Experimental Treatment 1 Intervention

Participants randomized to FoRKS will attend weekly HTN SMES classes separately from EUC participants. SMES classes will include the EUC curriculum stated above and an introduction to the upcoming FoRKS intervention. Following HTN SMES completion, FoRKS continues with home-delivered Mediterranean-style ingredient kits, food management lessons, and hands-on cooking classes in one's own kitchen. Classes are led by registered dietitians via Webex. Classes are held twice per week thru Week 12, then only once per week through Week 16.

Group II: Enhanced Usual Care (EUC) Active Control 1 Intervention

Participants randomized to EUC will have access to existing usual primary care services. They will also be enrolled in Hypertension Self-Management Education and Support (SMES) class ("Hypertension group"), which is an existing CDC-endorsed program offered at Eskenazi Health to provide information and skills for managing hypertension (HTN). Classes are led by registered dietitians via Webex.

Enhanced Usual Care (EUC) is already approved in Canada for the following indications:

Findings from Research

A systematic review of 10 studies on food provision programs for patients with type 2 diabetes or prediabetes showed that those including nutrition education consistently reduced HbA1c levels, indicating improved diabetes management.

Programs varied widely in their design and implementation, but those that incorporated nutrition education—covering topics like general nutrition and fruit/vegetable consumption—tended to yield better dietary quality and health outcomes compared to those without such education.
