TL;DR: A 24-hour waist-worn accelerometry protocol implemented in U.S. children may produce an important increase in wear time compliance that also provides an opportunity to study the total sleep episode time separate and distinct from physical activity and sedentary time detected during waking-hours.

TL;DR: The RSA is a refinement of the previous algorithm, allowing researchers who use a 24-h waist-worn accelerometry protocol to distinguish children's nocturnal sleep (including night time wake episodes) from daytime activities.

TL;DR: The low proportion of children engaging in moderate-to-vigorous physical activity and accumulating relatively more LIPA than SB had the lowest DXA-BF%.

TL;DR: Parent-targeted mobile phone interventions are feasible, yet more intense interventions may be needed to support parents’ efforts to increase their children’s physical activity to levels that approximate national recommendations.

TL;DR: Detailed accelerometer paradata is useful for standardizing communication, facilitating study management, improving the representative qualities of surveys, tracking study endpoint attainment, comparing studies, and ultimately anticipating and controlling costs.
