Fighting the obesity problem may need more than education
- With more Hongkongers considered either overweight or obese, a tougher approach to the problem may need to be considered such as regulations and taxes on sugary food and drinks
Obesity is a global health problem that societies, Hong Kong’s included, are struggling to deal with. Whether it is a disease, as some people are trying to have governments recognise, is a matter of debate. With such a classification involving the likelihood of laws, enforcement and financial obligations, there is an obvious reluctance for officials to make such a decision. But whether it is a chronic illness, a condition or the result of behavioural choices, what is important is that authorities push ahead with concerted efforts to stem what is increasingly being described as an epidemic and if those measures fail, to consider more far-reaching action.
The government’s strategy to fight the problem is based on awareness through education, labels on food products and setting guidelines on salt and sugar consumption. It uses the body mass index, commonly referred to as BMI, to determine what constitutes being normal, overweight or obese for adults: a formula based on calculating weight in kilograms divided by the square of the person’s height in metres, with a figure of 25 or more being overweight, and 30 and above obese. Different calculations are needed for children and the index is not accurate for those with exceptional bodies, such as athletes. An above-normal BMI is considered a risk factor for cardiovascular diseases including heart ailments and stroke, diabetes and some cancers, among them breast, ovarian, prostate and kidney.
