Abstract
Limited availability of desirable destinations within walkable distances and unsuitable weather may adversely affect physical activity among adolescents on weekends. This study examines evidence for associations between objective measures of local environment and physical activity levels of adolescents.
Students (n
=
152, 59% male; mean age, 13.7 years) from 10 neighborhoods with schools in four communities wore TriTrac-R3D accelerometers recording physical movements on weekends. Minute-by-minute data were summed over 15-minute intervals providing estimates of proportion of time spent in moderate and vigorous physical activity (MVPA) and (log) mean physical activity levels on weekends (n
=
7,506 intervals). Objective measures of neighborhood characteristics were calculated using geographic information systems including average daily traffic, housing density, open space, and density of employees per square kilometer in youth destinations. Linear mixed models were fit examining associations between neighborhood environmental variables and accelerometer measures of physical activity, controlling for time, day, age, body mass index, gender of respondent, race/ethnicity, precipitation, and temperature deviation.
On weekends, the presence of greater densities of employees in neighborhood destinations serving youth (β
=
3.96,
p
=
0.050) was directly associated with MVPA, independent of student characteristics.
Young people attending schools in neighborhoods characterized by greater densities of employees in destinations for youth are more physically active on weekends. Compared with neighborhoods with lower densities, attending a school in neighborhoods with higher densities of employees in potential destinations for youth may contribute to participation in an additional 30
minutes of MVPA per day on weekends.
