Defining metabolic syndrome with harmonised criteria including South Asian waist cut-offs, and prescribing combined exercise, sitting reduction and lifestyle change.
Learning objectives
- List the harmonised criteria for metabolic syndrome
- Apply population-specific waist cut-offs
- Prescribe combined exercise for metabolic syndrome
- Integrate sitting reduction, diet and sleep
Before this lesson
Why this matters
Metabolic syndrome substantially raises the risk of cardiovascular disease and type 2 diabetes. It is common among South Asians, often at lower body weights.
Harmonised criteria (3 of 5) [alberti2009]
| Criterion | Threshold |
|---|---|
| Waist circumference | Population-specific (South Asian commonly ≥90 cm men, ≥80 cm women) |
| Triglycerides | ≥150 mg/dL (or treatment) |
| HDL cholesterol | <40 mg/dL men, <50 mg/dL women (or treatment) |
| Blood pressure | ≥130 systolic or ≥85 diastolic (or treatment) |
| Fasting glucose | ≥100 mg/dL (or treatment) |
Prescription
| Component | Guidance |
|---|---|
| Aerobic | 150–300 min/week moderate, progressing [garber2011] |
| Resistance | 2–3 days/week |
| Sitting | Break up prolonged sitting; high activity offsets sitting risk [ekelund2016] |
| Sleep | 7+ hours supports cardiometabolic health [stonge2016] |
Common mistakes and misconceptions
Case study
A 42-year-old with a normal BMI but 94 cm waist, high triglycerides and borderline BP adopts walking, strength training and earlier bedtimes. After 6 months, waist and triglycerides fall below thresholds.

- Explain metabolic syndrome to a client.
Key takeaways
- Metabolic syndrome is diagnosed when 3 of 5 risk factors are present.
- Waist cut-offs are population-specific; for South Asians commonly ≥90 cm (men) and ≥80 cm (women).
- Combined aerobic and resistance training improves multiple components.
- Reducing sitting and improving diet and sleep add further benefit.
