^a Presented as the mean (standard deviation) unless otherwise denoted by percent, %; reported as percentage of column total. ^b Moderate-to-vigorous physical activity (MVPA) defined as ≥2200 counts per minute, as measured via accelerometry and expressed as average minutes of activity per hour of wear time. ^c Sedentary behavior defined as <100 counts per minute, as measured via accelerometry and expressed as average minutes of activity per hour of wear time. ^d The Heathy Eating Index (HEI) was constructed using dietary data from the Block Food Screener for Kids. Scores range from 0 to 50, with higher scores indicating better diet quality. ^e Index score was calculated using data from the American Community Survey 5-year estimates for the period 2008–2012. Neighborhood defined as census tract corresponding to participant’s home address. The index has a mean of zero and standard deviation of 1.
