Bivariate and multivariate models were run to assess any relationship between each independent variable (socio-demographic factors, school environment, parental or family factors, knowledge about menstruation and its hygienic management and disposable sanitary napkins use) and outcome variables (disposable sanitary napkins use and absenteeism from school).
10 Given that the majority of the subjects in the present study were school-aged, the school environment is an important factor to consider.
This suggests that other factors of school environment could explain PA level differences, such as social exclusion or playground issues, for example.
Other contextual variables (e.g., school connectedness, social support) available from the IYS were considered as possible protective factors in the school environment against bullying; however, conceptually, they function as possible intermediates impacted by law and should not be adjusted for in the models.
Additional studies examining gender differentials in the associations between factors of the school environment and student PA are warranted.
In the light of our demonstrated sex differences also during school age, one may surmise that factors related to school environment might affect girls and boys differently.
This may be explained in part by factors in the school environment, such as constant visual observation of the children and focused training of teachers and staff.
The purpose of this cross-sectional study was to explore gender differences in the association between factors of the school environment and students' time spent in PA.
Experts consider teaching staff as the main responsible for the creation of a beneficial school environment, apart from being the principal factor in the origin of conflict (91%).
The intervention focused on changes in instructional practices and the school environment to affect personal, social, and environmental factors related to physical activity.
In addition to the primary interventions effects, the study assesses the moderating effect of the school environment on BMI, blood pressure, cardiovascular risk factors, and quality of life.
