1Trends between 2008 and 2013, p-values were calculated with generalized linear regression model including schools as random intercept, adjusted for overweight.
2Difference between grades 1–2 in 2008 and grades 3–4 in 2010, p-values were calculated with generalized linear regression model including schools as repeated subject.
