Which statement best describes the use of growth charts in preschool preventive care?

• A. They track weight, height, and BMI and are used to monitor percentile changes.
• B. They focus only on height.
• C. They help identify growth patterns and potential concerns when plotted over time.
• D. They are based on a single measurement.

Answer: (C)

Growth charts are best understood as tools to track a child’s growth trajectory over time rather than rely on a single measurement. In preschool preventive care, clinicians plot serial measurements of weight, height (or length), and often BMI on age-appropriate percentile curves. The value comes from seeing how a child moves along those curves across visits—whether they stay on a stable percentile, cross upward or downward, or show a mismatch between height and weight growth. This pattern helps identify potential concerns such as undernutrition, growth faltering, or risk for overweight/obesity early enough to intervene.

So the key idea is that growth charts illuminate growth patterns and potential issues when data are plotted over time, not from isolated measurements.
