Points to Note for Parents:

I. Body weight of Hong Kong children

According to the findings of the Healthy Exercise for All Campaign Physical Fitness Test for the Community announced in 2012, about one fourth of the children in Hong Kong were overweight or obese. Similarly, statistics of the Student Health Service of the Department of Health for 2012 also revealed that about one in five primary students were overweight or obese. These findings reflect that children in Hong Kong do not have sufficient physical activity. Parents should encourage their children to exercise regularly in order to develop a healthy lifestyle and maintain their body weight within an appropriate range by proper means.


II. Why should we manage our body weight?

Being overweight may lead to the accumulation of excessive fat, which in turn increases the risk of such diseases as hypertension, cardiovascular disease, type II diabetes, gall stone and some types of cancer (e.g. colorectal cancer).

Other disadvantages of being overweight:
III. How to define obesity?
  1. A ratio of weight to height can be used to assess whether a person is obese or not.
    Definition of obesity: Body weight being 20% higher than the median "weight for height".

Weight-for-Height Chart



The Weight-for-Height Chart is an instrument to assess if the weight is proportional to the height of a child. For boys taller than 175 cm and girls taller than 165 cm, their weight status should be assessed by the Body Mass Index (BMI), which is applicable to individuals aged 18 or above.


  1. Checking the Weight-for-Height Chart is one of the methods to determine whether a person is underweight or overweight. However, measuring the level of subcutaneous fat and assessing the percentage of body fat using a bioelectrical impedance analyser are more accurate methods of assessment in the following situations:

    • Children who exercise regularly have more muscles and less fat.  They may be overweight but healthy.

    • Some children who are not overweight may have muscle mass that is way below standard and body fat far higher than the normal level.  They are considered obese despite having a normal body weight.
