The Relationship Between Physical Activity and Body Mass Index (BMI) of Young Children
Abstract
This study aims to analyze the relationship between physical activity and Body Mass Index (BMI) in early childhood children at the Preschool Center. The research uses a quantitative approach with a correlational design. The sample consisted of 32 young children and their parents, selected using purposive sampling. Data on physical activity was collected through a questionnaire filled out by the parents, while BMI data was obtained by measuring the children's weight and height, which were then converted based on BMI standards according to age and sex. Spearman Rank correlation. Data analysis was carried out using the Spearman Rank correlation test because the data were not normally distributed. The analysis results showed a correlation coefficient (Spearman’s rho) of -0.331 with a significance value (p) of 0.065. These results indicate that there is a negative relationship with a weak correlation between physical activity and Body Mass Index, but the relationship is not statistically significant. This finding suggests that physical activity is not the only factor affecting the Body Mass Index of young children. Other factors such as diet, nutritional intake, genetics, and environment are also suspected to play a role in determining children's nutritional status. Therefore, comprehensive efforts are needed to support the optimal growth and development of children.
