positive relationship between health and academic achievement (Bird &
Markle, 2012; Ryzin, Gravely, & Roseth, 2009). Overall health and body
image did not show significant as predictors in our model.
In fourth set of models, the variation in reading, mathematical and
scientific literacy scores is analyzed using predictors of academic self-con-
cept, sense of belonging to school, frequency of bullying in the school,
having goals for one’s future, motivation to have good grades in school
(extrinsic motivation), and school climate. Socio-economic and cultural
status is again used for controlling.
