Abbreviations: CI = confidence interval; MVPA = moderate to vigorous physical activity
a
From mixed-effects regression models adjusted for child age, gender, and race/ethnicity, dance type, instructor experience, class size, and nesting of participants within classes; e.g., “c” means that percent of MVPA during the segment different significantly from the percent of MVPA during Routine/practice
b
Calculated as the difference in percent of segment in MVPA between the segments, from the adjusted means
