Note. Percentages are weighted and may not add to 100 because of rounding.
aFrequency and duration of physical education were reported by teachers, who used the categories provided in the table for frequency and duration.
bEstimates may be unstable because the coefficient of variation was more than 30%.
cMinutes per week of physical education was estimated by multiplying the median frequency by the median duration and categorized by minutes per week as low (0–35), medium (36–69), or high (70–300).
