Smartwatch May Track AD Status in Children

Wearable-derived scratching measures align with disease activity and short-term treatment response in pediatric patients with atopic dermatitis.

1

Smartwatch-measured nighttime scratching correlates moderately with disease severity in pediatric atopic dermatitis patients.
2

The study involved 50 children aged 4 to 15 years who wore an Apple Watch to track scratching metrics during topical therapy.
3

Scratching metrics showed moderate correlations with clinical severity, with coefficients ranging from 0.60 to 0.64 at baseline.
4

The SBI-based model effectively distinguished patients achieving significant clinical improvement, with an area under the curve of 0.78.
5

Further validation is needed before applying smartwatch-derived metrics as objective indicators of atopic dermatitis activity.
