Hierarchical Analysis of Physical Activity Determinants in Brazilian Adolescents: A Cross-Sectional Study.

ABSTRACT:

Background

Physical inactivity during adolescence remains a major public health concern, yet its multifactorial determinants are not fully understood in low- and middle-income settings.
