PE11.3-4 | Childhood Obesity Assessment — Summary & Reflection

KEY TAKEAWAYS

Assessment of an obese child requires a structured, systematic approach covering history, anthropometry, and clinical examination. The 24-hour dietary recall (probing every meal, snack, and beverage with portion sizes) and physical activity assessment (MVPA + screen time) are the key history tools targeting modifiable drivers. Anthropometric measurements must follow precise technique: weight (calibrated scale, light clothing), height (stadiometer, Frankfurt plane), BMI (weight ÷ height²) plotted on IAP age/sex charts (overweight ≥85th, obese ≥95th percentile), waist circumference (midpoint 12th rib–iliac crest, mid-axillary line; >90th percentile = abdominal obesity), hip circumference (widest buttock point), and blood pressure (correct cuff size). External markers on examination — acanthosis nigricans (insulin resistance; seek at neck nape, axillae, groin), striae (silver-white = primary obesity; purple = Cushing flag), pseudogynaecomastia vs true gynaecomastia (palpation distinguishes adipose from glandular tissue) — add essential metabolic and aetiological information. Findings are synthesised into a structured assessment documenting weight classification, abdominal obesity, blood pressure status, aetiological classification (primary vs secondary), and a metabolic investigation and management plan.

REFLECT

Think back to a clinical encounter — a real one, or the vignette in this module — where an obese child was being assessed. Was the examination systematic, or did it focus only on the obvious (the scales)? Were the correct landmarks used for waist circumference? Was the blood pressure cuff the right size? Reflecting on Kolb's cycle: what deliberate practice would you undertake to make these technical steps automatic — so that in an OSCE or a busy outpatient clinic, you are not searching your memory for the waist measurement landmark, but simply performing the correct technique with confidence? Consider seeking out supervised practice sessions with a paediatric nutritionist or endocrinology team during your clinical posting.
