Frequently Asked Questions
What is a healthy BMI for Singaporeans?
According to Singapore's Health Promotion Board (HPB), a healthy BMI for Asian adults is 18.5–22.9. This is lower than the WHO global range of 18.5–24.9, as Asians have a higher proportion of body fat at the same BMI compared to Caucasians.
Why does Singapore use different BMI cutoffs from the WHO?
Research shows that Asians, including Singaporeans, have higher body fat percentages and greater risk of obesity-related diseases like diabetes and heart disease at lower BMI values. The HPB Asian cutoffs (overweight ≥23.0, obese ≥27.5) better reflect these health risks.
What is the average BMI in Singapore?
The average BMI in Singapore is approximately 23.5 for adults, placing the average Singaporean in the overweight category by HPB standards. Around 40% of Singaporeans aged 18–69 are classified as overweight or obese by Asian BMI standards.
Is BMI accurate for Singaporeans?
BMI is a useful population-level screening tool but has limitations — it does not measure body fat directly or account for muscle mass. For Singaporeans, the Asian HPB cutoffs provide a more accurate health risk assessment than WHO standards. Those with high muscle mass (athletes) may have elevated BMI without excess fat.
