What is the primary purpose of plotting growth on standard growth charts during preventive visits?

• A. To set a fixed target height for the child.
• B. To diagnose every health condition.
• C. To monitor percentile changes and detect growth concerns.
• D. To compare the child with every other child in the class.

Answer: (C)

Plotting growth on standard growth charts is about watching how a child grows over time, not aiming for a fixed height or ranking against others. By charting height, weight, and BMI percentiles at routine visits, clinicians can detect changes in growth velocity or crosses of percentiles that may signal nutritional problems, chronic illness, endocrine issues, or other concerns. If the child maintains a consistent percentile with normal velocity, growth is typically appropriate. When percentiles shift up or down significantly, it prompts a more thorough assessment—history, diet review, physical exam, and possibly further testing—to identify underlying causes. Growth charts are screening tools used to flag potential problems, not to set targets, diagnose every condition, or compare a child to classmates.
