To monitor secular changes in growth and the impact of the obesity epidemic in Hong Kong children.

Conclusion

The study shows significant secular changes in child growth and an increasing obesity epidemic among Hong Kong children.

Supporting Evidence

  • 16.7% of children were classified as overweight or obese in 2005/6.
  • Obesity rates increased by 5.1% since 1993.

Takeaway

The study found that Hong Kong children are getting taller and heavier, and more of them are becoming overweight or obese.

Methodology

Limitations
