Gulfnews: UAE to formulate anti-obesity plan
The UAE records one of the highest rates of obesity in the world, higher than the US. It is blamed on a sedentary lifestyle and easy access to food high in fat and calories. It also has one of the highest rates of diabetes, one of many obesity-related diseases, with an estimated one in five adults affected. Dr Huda Al Suwaidi, a consultant in family medicine at the ministry, said bad diet and lack of physical exercise were causing a wide range of health problems.

Dr Abdul Rahaman Obeid, director of the Bahrain-based Arab Centre for Nutrition, said obesity prevalance in the Gulf region ranged between 10 to 15 per cent among children in primary schools, 15 to 30 per cent in students at the intermediate level and 20 to 40 per cent in students at the secondary level. He said the statistics were from a recent report of the World Health Organisation (WHO). “Obesity in married women reached levels as high as 50 to 75 per cent due to recurrent pregnancy,” he said.
With obesity, prevention was by far better than treatment. “Therefore effective measures ought to be taken to counter the phenomenon through reduced intake of fast-food rich in fats and soft drinks,” said Dr Sinan Hunood, a specialist in diabetes at Al Noor Hospital in Abu Dhabi. “It is a mistake to depend on one type of meal only. One needs between 45 to 65 per cent of starches, 10-35 per cent of proteins, 20-35 per cent of fats in addition to fibres such as lettuce every day.”
Dr Hunood said a new phenomenon has become apparent, and that was the spread of adult diabetes among children because of obesity or what was often abbreviated as ‘MODY’.
