Researchers of Pennsylvania health policy extracted data of 176 Chinese overweight teenagers through investigation. They found that 69% of these teenagers underestimated their body weights. And 72% mother of the overweight teenagers judged their children to be normal weight or underweight.

Yao Nengliang， a health policy and management expert said “A number of overweight teenagers in China underestimate their weight， and are unlikely to change their dietary structures and exercise patterns. However， if not， they are probably to become extremely obese and will face lots of health problems， just like what we often see now in America.”

Wang Longde， former Deputy Minister of Health， President of China Preventive Medicine Association believes that children obesity is mainly caused by unhealthy lifestyles. “And one of the major reasons is drinking excessive sugary soft drinks. Now many countries have legislated against this， and China can learn from them.”

美國賓夕法尼亞州衛(wèi)生政策研究人員曾經(jīng)從調(diào)查中抽取176名中國超重青少年的數(shù)據(jù)，經(jīng)研究發(fā)現(xiàn)，其中69%的青少年低估了自己的體重。此外，有72%的母親對自己體重超重的孩子給出了體重正?；虿蛔愕脑u判。

美國衛(wèi)生政策與管理學專家姚能良（音）說：“中國許多超重青少年都低估了自己的體重，不大可能采取措施改善膳食和鍛煉模式。如果不改變，他們很可能會變得極為肥胖，將來會面臨許多健康問題——就像我們在美國經(jīng)?？吹降那闆r一樣。”

原衛(wèi)生部副部長、中華預防醫(yī)學會會長王隴德認為，兒童肥胖的主要原因是不良生活方式造成的，“其中一個主要原因就是飲用含糖軟飲料，這對造成兒童的肥胖是非常重要的?，F(xiàn)在許多國家要對此提出一些立法的限制，中國也應該效仿。”

It is much harder to lose weight for obese children than obese adults， because children obesity is not just the increase of adipocyte as the adults do， but the increase in both adipocyte in number and size.

Wang said that， nowadays most of the common diseases， including infectious and chronic diseases are to some extent related with lifestyle. The reason for the rising of children obesity rate is mainly improper diet： no breakfast but excessive dinner， being in favor of high-calorie and high-fat fast food and high-sugar drinks like Coke， preferring dessert and chocolate， long TV time.

“Among the children aged 0 to 6 years old in the city of China， the rate of overweight and obese has been up to 8%. The rate for teenagers aged 7 to 17 years old has even reached to 21%. If the trend of becoming overweight and obesity are not be curbed， it would be a disaster for us.”

兒童肥胖減肥比成年人要困難，因為兒童肥胖不單像成年人那樣僅僅是脂肪細胞的體積增大，而兒童肥胖是脂肪細胞的個數(shù)和體積同時增多和增大，所以解決起來更困難。

王隴德提醒說，現(xiàn)在基本上絕大部分的常見疾病，包括傳染病和慢性病，都和生活方式相關。造成兒童肥胖比例上升的主要原因是飲食不當：有人愛睡懶覺不習慣吃早餐，晚餐過量；喜歡吃高熱量、高脂肪的快餐，喜歡喝可樂等飲料；習慣吃甜點心、巧克力；長時間看電視等。

“中國城市現(xiàn)在0歲-6歲的兒童，超重加肥胖已經(jīng)達到8%，7歲-17歲的青少年超重加肥胖已經(jīng)達到了21%。如果不及早注意、做出改變的話，這將是我們民族的災難?！?/p>
