General practitioners cannot rely on reported weight and height of children

Area of Science:

• Pediatric Health
• Clinical Measurement Accuracy
• General Practice Research

Background:

• Accurate weight and height measurements are crucial for general practitioners (GPs) in screening, signaling, and treating childhood obesity.
• Reliance on reported data can compromise the accuracy of these essential clinical assessments.
• Understanding discrepancies between reported and measured anthropometrics is vital for effective pediatric care.

Purpose of the Study:

• To investigate discrepancies between reported and measured weight and height in children across different weight categories (underweight, normal-weight, overweight).
• To analyze these differences specifically within the context of a general practitioner setting.
• To evaluate the reliability of self-reported and parent-reported anthropometric data in pediatric populations.

Main Methods:

• Utilized a cohort of 715 children aged 2-17 years.
• Collected data on both reported and directly measured weight and height.
• Employed paired t-tests to compare the means of reported versus measured values.

Main Results:

• Weight and height reporting inaccuracies were observed across various age and weight groups.
• Younger children (2-8 years) showed reported weights that were significantly higher for underweight and lower for overweight categories compared to measured values.
• Older children (9-17 years) consistently reported lower weights than measured, particularly in normal-weight and overweight groups.

Conclusions:

• General practitioners should not depend on reported weight and height data from parents or children.
• Direct measurement of weight and height in a clinical setting is recommended when under- or overweight is suspected.
• Accurate anthropometric data collection is essential for appropriate pediatric health management.
