Adolescent BMI / growth chart interpretation
Appears 0×
Teaching point — how the wording changes the answer
In ages 2-18 use BMI-FOR-AGE percentile, not adult cut-offs. >=85th = overweight, >=95th = obese. So 'BMI 27' alone is read off the chart; if the stem states >=95th percentile the answer is OBESE, not just overweight. Adult absolute cut-offs do NOT apply, but the chart itself IS valid for this age (so 'cannot use BMI under 18' is wrong).
