Physical activity in youth: prevalence, risk indicators, and solutions

Area of Science:

• Public Health
• Pediatrics
• Exercise Science

Background:

• Youth physical activity levels are a significant public health concern.
• Meeting daily physical activity standards is crucial for child development and long-term health.
• Few studies have identified specific, modifiable factors associated with meeting physical activity guidelines in youth.

Purpose of the Study:

• To identify developmental, environmental, psychological, social, and demographic factors associated with meeting the Health Canada physical activity standard in youth.
• To determine which of these factors remain significant after multivariate adjustment.

Main Methods:

• A survey was administered to 4197 students in grades 5 to 8 in Saskatoon.
• Data collected included whether students met the Health Canada standard for daily physical activity.
• Associated risk factors for not meeting the standard were analyzed using multivariate adjustment.

Main Results:

• Only 7% of surveyed youth met the Health Canada daily physical activity standard (over 1 hour of moderate-to-vigorous activity).
• Five factors were independently associated with meeting physical activity standards: employed fathers, daily parental observation of physical activity, daily peer encouragement, lack of peer teasing for sports performance, and playing sports with coaches more than four times weekly.
• These factors showed significant odds ratios (ORs) ranging from 1.19 to 2.29 (P < .05).

Conclusions:

• Low rates of physical activity among youth necessitate targeted interventions.
• Identifying key independent risk indicators can help focus limited resources for effective community-based programs.
• Interventions should consider parental involvement, peer support, and structured sports engagement.
