NHS / NICE scale · waist as the determinant
Central Adiposity Screener
BMI proposes a rating. Waist circumference then decides whether that rating holds — confirming it, raising it, or failing to back it up. BMI is highly specific but misses roughly half of people carrying excess fat, so a normal BMI with a big waist is under-rated, and a high BMI with a slim waist may be over-rated. The waist is the tie-breaker.

Interpretation
Your waist sits below the action level, yet waist-to-height is 0.517 — at or above 0.50. That keeps the BMI rating of Increased standing rather than downgrading it. Waist-to-height often flags central adiposity a single waist threshold misses, especially in shorter people.
