The relationship between motor skill proficiency and body mass index in preschool children

Area of Science:

• Pediatric Health
• Motor Development
• Childhood Obesity

Background:

• Motor proficiency is crucial for children's physical activity and overall development.
• Rising rates of childhood obesity necessitate understanding its impact on various developmental domains.
• Body Mass Index (BMI) is a common indicator used to classify weight status in children.

Purpose of the Study:

• To investigate the association between motor proficiency and Body Mass Index (BMI) in preschool-aged children.
• To determine if BMI status influences motor skill performance in young children.

Main Methods:

• Thirty-eight preschool children (ages 4-6 years) participated in the study.
• Body Mass Index (BMI) was calculated for each child.
• Motor proficiency was assessed using the Movement Assessment Battery for Children-2 (MABC-2).
• Statistical analyses included correlation and t-tests to compare MABC-2 scores across BMI categories.

Main Results:

• No significant correlation was found between overall BMI and MABC-2 percentile ranks (r = -.237).
• Significant differences in MABC-2 percentile ranks were observed between children in the high BMI group compared to the low (p = .042) and medium (p = .043) BMI groups.
• Children with higher BMI tended to have lower motor proficiency scores.

Conclusions:

• Preschool children classified as overweight or obese may demonstrate reduced motor proficiency compared to their normal or underweight peers.
• A direct relationship exists between motor proficiency and BMI in the preschool population, highlighting potential implications for early intervention.
