Agreement Between Apple Watch and Actical Step Counts in a Community Setting: Cross-Sectional Investigation From the Framingham Heart Study.

ABSTRACT:

Background

Step counting is comparable among many research-grade and consumer-grade accelerometers in laboratory settings.

Objective

The purpose of this study was to compare the agreement between Actical and Apple Watch step-counting in a community setting.

Methods

Among Third Generation Framingham Heart Study participants (N=3486), we examined the agreement of step-counting between those who wore a consumer-grade accelerometer (Apple Watch Series 0) and a research-grade accelerometer (Actical) on the same days. Secondarily, we examined the agreement during each hour when both devices were worn to account for differences in wear time between devices.

Results

We studied 523 participants (n=3223 person-days, mean age 51.7, SD 8.9 years; women: n=298, 57.0%). Betw
