Evaluation of Progress Using Asia-Pacific Cut-offs
The woman’s current BMI is calculated as 67 ÷ (1.59 × 1.59) =
26.5 kg/m², down from
26.9 kg/m² three months ago. Under the Asia-Pacific classification, a BMI of
25 kg/m² or greater is already considered obese, not merely overweight. Therefore, although her BMI has decreased slightly, she remains in the
obese range by this regional standard .
Her waist circumference improved from
88 cm to
82 cm, a reduction of
6 cm. However, the cut-off for abdominal obesity in women is
80 cm, so her current waist measurement is still at or above the threshold
[2]. This distinction matters because
abdominal obesity is an independent risk factor for noncommunicable diseases and is not fully captured by BMI alone [2]. A person can have a normal BMI but still carry excess visceral fat, which is why waist circumference is measured separately in NCD risk assessment.
Her physical activity increased from
30 minutes to
160 minutes of brisk walking per week. This now exceeds the commonly recommended minimum of
150 minutes of moderate-intensity activity per week. The change in activity level is substantial and indicates that the behavioral intervention is being adopted.
Key point! The plan is working, but success is defined by reaching the cut-offs, not by the speed of weight loss. A loss of only
1 kg over three months may seem small, yet it is accompanied by a meaningful reduction in waist circumference and a large increase in physical activity. Gradual change is often more sustainable than rapid weight loss.
Watch out! Do not interpret a BMI of
26.5 kg/m² as “overweight” using Western cut-offs. In the Asia-Pacific region, the threshold for obesity is lower (
25 kg/m²) because metabolic complications appear at lower BMI levels in Asian populations . The same principle applies to waist circumference: the cut-off for women is
80 cm, not the higher values used in some other guidelines
[2].
The most accurate evaluation is that she is improving but has not yet reached either the BMI or waist circumference target. Follow-up should continue, and the current plan should be reinforced rather than changed or discontinued.
