Does excess mass affect plantar pressure in young children?

Area of Science:

• Pediatrics
• Biomechanics
• Orthopedics

Background:

• Childhood obesity is a growing concern with potential long-term health implications.
• Understanding the biomechanical effects of excess weight in children is crucial for early intervention.

Purpose of the Study:

• To investigate the impact of overweight and obesity on dynamic plantar pressures during gait in preschool children.
• To compare plantar pressure variables between overweight/obese and non-overweight preschool children.

Main Methods:

• Dynamic plantar pressure analysis was performed on 17 overweight/obese and 17 non-overweight preschool children.
• Key variables measured included contact area, peak pressure, and force-time/pressure-time integrals across different foot regions.

Main Results:

• Overweight/obese children exhibited larger foot sole contact areas and generated higher forces during walking.
• Despite increased contact, overweight/obese children had significantly higher peak pressures and integrals in the midfoot.
• Higher force-time and pressure-time integrals were observed in the midfoot of overweight/obese children.

Conclusions:

• Increased midfoot plantar pressures in overweight/obese preschoolers suggest a higher vulnerability to stress-related injuries.
• The findings highlight potential risks for bony fatigue and soft tissue damage in the midfoot of obese children.
• Further research is needed to explore the long-term consequences on foot health and physical activity.
