Background
Simple measurements such as weight, height and waist circumference are widely used to screen for health risks because they are cheap and easy to repeat. They are not diagnoses, but tracked over time they show whether lifestyle changes are working.
Research has shown that Asians tend to develop conditions such as type 2 diabetes and heart disease at lower body weights than Europeans. That is why the Health Promotion Board recommends lower BMI cut-offs for Singaporeans, with 23 marking the start of moderate risk.
