Individual and environmental parameters in children with and without developmental coordination disorder: associations with physical activity and body mass index.

Introduction: Physical Activity (PA) is a complex behavior, and the relevance of other factors such as BMI, SES and children's behavior at school and home still lacks investigation for children, especially those at risk or with Developmental Coordination Disorder (DCD). The objective of this study was to examine whether socioeconomic status (SES), school's spaces for children's movement, active play, screen time, motor skill proficiency, perceived motor competence, and engagement in the physical education lessons were associated with PA and BMI in children with typical development (TD), at risk of DCD (r-DCD), and with DCD.

Methods: Children ( = 352; 4-10-year-old) from six public schools in a major urban city, in southern of Brazil, were assessed regarding motor skill proficiency (locomotor and ball skills), perceived motor competence, and weight status.
