Interventions

  • Allergen Avoidance Intervention - group 1 — BEHAVIORAL
    Participants received standardized allergen avoidance measures, with the primary goal of reducing allergen exposure levels. Specific measures included regularly implementing allergen avoidance behaviors and recording environmental parameters. The operational details were carried out in accordance with the research protocol. During the intervention period, the original medication treatment was maintained.
  • Exercise Intervention - group 1 — BEHAVIORAL
    Participants receive a standardized exercise promotion program, which included, but is not limited to, regular face-to-face guidance, motivational interviews, personalized goal setting, action planning, and self-feedback and adjustment based on objective activity monitoring data. During the intervention period, the subjects maintain their original medication treatment plans unchanged.
  • Dietary Intervention - group 1 — BEHAVIORAL
    Participants receive standardized guidance on a healthy diet pattern. The intervention measures included, but are not limited to, guidance from nutritionists, provision of food materials, and monitoring of dietary compliance. During the intervention period, the subjects maintain their original medication treatment plans unchanged.
  • Allergen Avoidance Intervention - group 2 — BEHAVIORAL
    Participants eceive usual care, consisting of standard pharmacological treatment. They are instructed to maintain their baseline lifestyle and activity levels without participating in additional allergen avoidance interventions.
  • Dietary Intervention - group 2 — BEHAVIORAL
    Participants continue their routine clinical treatment and do not receive dietary interventions. At baseline, all participants watch a 10-minute asthma self-management education video that does not contain dietary advice.
  • Exercise Intervention - group 2 — BEHAVIORAL
    Participants receive usual care, consisting of standard pharmacological treatment. They are instructed to maintain their baseline lifestyle and activity levels without participating in additional exercise interventions.

Study Details

The aim of this study is to develop and validate a digital screening tool and digital management system for asthma and allergic diseases among Chinese adults and to evaluate the effectiveness of integrated non-pharmacological interventions in improving disease control and quality of life. The digital management cohort consists of: * At least 12 months of longitudinal monitoring of symptoms, environmental exposures, and health behaviors via a digital platform, supplemented by regular clinical assessments. * 3x embedded randomized controlled trials (RCTs) evaluating the clinical efficacy of non-pharmacological strategies: allergen avoidance (anti-mite bedding), physical activity (wearable-guided exercise), and dietary management (Mediterranean diet).
