Approximately 320 subjects who are determined fully eligible will be randomly assigned (by chance, like flipping a coin) to participate in intervention Group A or Group B, where you will receive either 1 of the 2 asthma care programs~Both asthma care programs are for a year and offer patient education on asthma and health. In both asthma care programs, you will receive fact-based patient information on asthma and health. Additionally, in one of the programs, a registered dietitian will also provide nutrition counseling on how to follow the USDA recommended DASH diet. Both asthma care programs offer 3 individual sessions, 8 group sessions, and 11 phone consultations. Your first individual session will be in-person with a trained health coach on the ALOHA team. The remaining 2 individual sessions will be either in-person or remote, depending on what you and your coach decide. You will also attend the first 2 (of 8) group sessions in-person to build connection with your coach and peer participants in the group. You and your coach will then decide whether you should attend the remaining group sessions in-person or remotely. Your ALOHA health coach will offer you continued support by phone until you complete your 1-year program.~Study Visits at UIC: Irrespective of your asthma care group, all participants will be expected to visit UIC Study site 4 times over the next year, initially and then at 3 months, at 6 months, and finally at one year. You will meet with an ALOHA study coordinator for 2 hours at the initial and final visits and for 1 hour at 3 and 6 months. Before each visit, you will complete online surveys about your health and phone interviews about your diet. At each visit, you will complete a breathing test, a blood draw, a physical exam, and questions about your asthma, diet and exercise habits, use of asthma medications and dietary supplements.
The goal of the ALOHA trial is to investigate the efficacy of improved diet quality following a DASH behavioral intervention that has shown promising results in adults with uncontrolled asthma. DASH stands for Dietary Approaches to Stop Hypertension. This healthy diet is known to help people with high blood pressure manage their health. But physicians do not know if the DASH diet can also benefit patients with uncontrolled asthma. Researchers in the ALOHA study are trying to find out the answer to this important question.~Researchers at UIC are studying how 2 asthma care programs compare in terms of helping adults with uncontrolled asthma to improve their quality of life. Researchers also want to learn what might explain the differences in patient outcomes that they may see between the 2 programs.~The primary outcome will be asthma-specific quality of life. If the DASH behavioral intervention is found to benefit people with uncontrolled asthma, it would provide a practical, safe, and acceptable public-health intervention in the form of dietary modification to reduce the burden of asthma.
