• Conditions: Physical Activity; Sleep

• Registration Number: NCT03403816
• Lead Sponsor: Harvard School of Public Health (HSPH)

Brief Summary

This study will determine the effectiveness of a free before-school physical activity program, BOKS (Build Our Kids' Success), in increasing objectively measured physical activity levels among children in elementary and middle school in 7 schools in Massachusetts.

Detailed Description

This study will determine the effectiveness of a free before-school physical activity program, BOKS (Build Our Kids' Success), in increasing objectively measured physical activity levels among children in elementary and middle school in 7 schools in Massachusetts. The study focuses on capturing valid and objective assessments of student-level physical activity during BOKS program time and assessing the impact of the BOKS program on overall daily physical activity levels using minute-by-minute physical activity level data among elementary aged students. Data is also collected to understand how increasing physical activity may impact students' sleep.

Primary Outcome Measures

Name	Time	Method
Total steps per day	Participants wore a Fitbit activity monitor for up to 5 school days beginning with the before school period simultaneously for 24 hours/day	The primary outcome measure is a physical activity measure of how many steps per day participants took.

Secondary Outcome Measures

Name	Time	Method
Active minutes	Participants wore a Fitbit activity monitor for up to 5 school days beginning with the before school period simultaneously for 24 hours/day	A secondary outcome measure is a measure of how many minutes participants spent in light, moderate and vigorous activity per day.
Sleep duration	Participants wore Fitbit activity monitors for 24 hours for up to 5 school days	A secondary outcome measure is the amount of time participants spent asleep each night, measured by a Fitbit activity monitor, which collects a measure of total sleep time.
