Summary

Dietary intervention efficacy trials are distinctly lacking in asthma research. This pilot study aims to provide effect size estimates and justification, clinical trial and intervention feasibility data, and procedural materials for a full-scale randomized controlled trial that will determine the efficacy and mechanisms of action of the Dietary Approaches to Stop Hypertension (DASH)-a recommended dietary pattern based on proven cardiovascular benefits-as adjunct therapy to standard care for adults with uncontrolled asthma.

Detailed description

Dietary intervention efficacy trials are distinctly lacking in asthma research. This pilot study aims to provide effect size estimates and justification, clinical trial and intervention feasibility data, and procedural materials for a full-scale randomized controlled trial that will determine the efficacy and mechanisms of action of the Dietary Approaches to Stop Hypertension (DASH)-a recommended dietary pattern based on proven cardiovascular benefits-as adjunct therapy to standard care for adults with uncontrolled asthma. Eligible, consenting participants (n=90) will be randomized to receive usual care alone or combined with a DASH intervention. Follow-up assessments will occur at 3 and 6 months. By evaluating a dietary pattern approach to improving asthma control, this study could advance the evidence base for refining clinical guidelines and public health recommendations regarding the role of dietary modifications in asthma management.

Conditions

Interventions

Type	Name	Description
BEHAVIORAL	Dietary Approaches to Stop Hypertension dietary pattern	The intervention will employ a series of small group and individual sessions, followed by periodic telephone contacts, to help participants make appropriate dietary changes and develop the skills to maintain these changes over the long term. The initial 3 months of intensive intervention will involve 8 group and 3 individual sessions for 45-60 minutes each. During the next 3 months, participants will receive counseling phone calls once per month for 20-30 minutes each call. Group session sizes may range from 8-15 participants.
