N Odds Ratio (95% CI) b (p-value) N Odds Ratio (95% CI) b (p-value)
Grade 6 PE (≥150 min/week)b 401 2.10 (0.97-4.44) -- 388 2.01 (1.00-4.30) --
Grade 8 PE min/weekc 227 -- 18.66 (<.001) 218 -- 17.72 (<.001)
Delivery (Linear)d 231 3.77 (1.10-12.92) -- 222 3.45 (1.15-10.28) --
Grade 10 PE min/weekb 199 -- 9.12 (0.04) 192 -- 11.17 (0.01)
Delivery (Linear)d 204 0.51 (0.19-1.36) -- 197 0.42 (0.15-1.19) --

aModels were adjusted for neighborhood-level median household income, percent with post-sec education, school size, and school location.

bMixed effect logistic regression examining the odds of offering greater than or equal to 150 minutes of PE per week versus offering less than 150 minutes per week, in 2011–12 as compared to 2007–08.

cMixed effect linear regression, mean increase in minutes of PE per week between 2007–08 and 2011–12.

dMixed effect logistic regression examining the odds of offering PE as a linear course versus a semester course in 2011–12 as compared to 2007–08.

CI, confidence interval; b, unstandardized regression coefficient; Bolded estimates are statistically significant at p < 0.05.
