Joint physical activity and sedentary behavior in parent-child pairs

Area of Science:

• Physical activity and sedentary behavior research
• Parent-child dyadic interactions
• Public health and wellness

Background:

• Understanding parent-child joint physical activity is crucial for promoting healthy lifestyles.
• Sedentary behavior is prevalent among parent-child pairs, with limited research on joint engagement.
• Accelerometers and GPS devices offer objective measures of physical activity and proximity.

Purpose of the Study:

• To examine joint physical activity and sedentary behavior in parent-child pairs.
• To quantify the time spent in physical activity and sedentary behavior together.
• To identify factors associated with joint behaviors.

Main Methods:

• 291 parent-child pairs wore accelerometers and GPS devices for 7 days.
• Joint behavior defined as parent-child separation distance < 50m.
• Activity and proximity data analyzed for nonschool waking hours.

Main Results:

• Parents and children averaged 2.4 min/day in joint moderate-to-vigorous physical activity (MVPA) and 92.9 min/day in joint sedentary behavior.
• Children engaged in more MVPA when parents were nearby (10 min/day) than vice versa (4.6 min/day).
• Lower household income and older child age were linked to less joint MVPA; girls and older children/parents engaged in more joint sedentary behavior.

Conclusions:

• Significant opportunities exist to increase joint physical activity between parents and children.
• Shifting sedentary time to joint physical activity may yield health benefits, particularly for specific demographics.
• Interventions targeting families, especially girls, older children, and older parents, could promote healthier joint behaviors.
