The associations between individual and environmental
variables are summarised in Table 4. This table only presents
data for the aspects of school health promotion that had
an impact on one or more health indicators in participants.
Thus, schoolchildren whose teachers had received training on nutrition in recent years showed higher levels of physical activity (P = .010), a greater degree of compliance with
the Mediterranean diet (P = .020) and fewer daily hours of
screen time (P = .016) compared to peers whose teachers
had not received such training. Meanwhile, schoolchildren
attending schools with written or unwritten policies aiming at increasing the consumption of fruits and vegetables
reported a higher compliance with Mediterranean dietary
patterns (P = .017) and fewer hours of screen time per day
(P = .023). Lastly, when it came to the physical environment,
it is worth noting that students whose schools had sports
facilities within the school grounds or in the vicinity showed
higher levels of physical activity than students that did not
have access to such facilities (P = .023).
