Introduction
This study compares users of connected smart scale technologies with the general population in England, exploring how use of smart scale technology affects weight change.
Methods
The study used two datasets: the Health Survey for England (HSE) and a random sample of Withings Smart Scale users. The HSE is a cross-sectional survey of the general population in England, while the Withings Smart Scale data was obtained from users who created an account and stored their measurements.
The study examined the association between engagement with self-weighing and BMI change, using linear regression and multilevel Cox proportional hazard models.
Results
Among women, users of self-weighing technology had a mean BMI 1.62 kg/m² lower than the general population. Among men, users had a mean BMI 1.26 kg/m² greater than the general population.
Engagement with self-weighing was associated with recent weight change, with users more likely to self-weigh when they had recently reduced their BMI.
