Utility of Body Mass Index Quick Screening Tool for Assessing Nutritional Category of Children

Area of Science:

• Pediatric Endocrinology
• Public Health Nutrition
• Biostatistics

Background:

• Childhood obesity is a growing global health concern.
• Accurate screening tools are crucial for early identification and intervention.
• Existing screening methods require validation in diverse populations.

Purpose of the Study:

• To evaluate the diagnostic accuracy of a rapid Body Mass Index (BMI) screening tool.
• To compare the tool's performance against established Indian Academy of Pediatrics BMI charts.
• To determine the sensitivity and specificity for identifying different weight categories in children.

Main Methods:

• Retrospective analysis of 415 boys and 428 girls aged 8-14 years.
• Assessment of a quick BMI screening tool's performance.
• Comparison with Indian Academy of Pediatrics BMI charts for validation.

Main Results:

• The BMI tool demonstrated high sensitivity and specificity for normal weight and underweight children.
• Sensitivity for identifying overweight children ranged from 50% to 57.4%.
• Specificity varied for detecting overweight and obese children.

Conclusions:

• The rapid BMI screening tool is effective for identifying normal weight and underweight children.
• The tool's accuracy is limited in detecting overweight and obesity in children.
• Further refinement or alternative methods may be needed for comprehensive childhood weight status screening.
