Assesses pediatric growth using WHO and CDC growth charts with percentile and z-score calculations. Use when user asks to "plot growth", "check growth chart", "growth assessment", "growth percentiles", "is the child growing normally", "failure to thrive", "FTT workup", "pediatric BMI", mentions "growth velocity", "weight for age", "height for age", or needs growth trend analysis for a child. Do NOT use for adult BMI, adult weight management, or prenatal growth (use prenatal-visit-workflow).
Retrieve longitudinal height, weight, and head circumference Observations for a pediatric patient. Calculate age- and sex-specific percentiles and z-scores using WHO standards (0-2 years) and CDC growth charts (2-20 years). Assess growth velocity, BMI-for-age, and weight-for-length (under 2 years). Flag percentile crossing (shift of 2+ major percentile lines), failure to thrive criteria, obesity, and short stature triggers. Generate a structured growth assessment with referral recommendations when indicated.
