Is 115 lbs Healthy for a 15-Year-Old Girl? Context Matters

Weight alone cannot determine health. For a 15-year-old female, BMI-for-age percentile is the standard screening tool.

Assessment Steps

1. Obtain accurate height and weight.
2. Calculate BMI = kg/m².
3. Plot on CDC BMI-for-age growth chart (girls 2–20 years).

Interpretation

• 5th–84th percentile: Healthy weight.
• 85th–94th: Overweight.
• ≥95th: Obesity.
• <5th: Underweight.

Additional Factors

• Body composition (muscle vs. fat).
• Pubertal stage (early vs. late).
• Growth trajectory (crossing percentiles).
• Nutrition, activity, mental health.

Recommendation: Discuss with pediatrician or adolescent medicine specialist for personalized evaluation. Avoid dieting without professional guidance.
