2009年7月，美國研究人員發布的一份報告中指出，肥胖造成的疾病大約占用美國近10%的醫療費用，每年耗費約1470億美元。在過去10年中，美國花在肥胖相關健康問題上的醫療費用幾乎翻倍，肥胖引發的糖尿病、心臟病、關節炎等疾病治療費用由此上升89%。

在發達國家，肥胖與超重人口比例嚴重超標，已經成為他們發展人口素質，促進人口健康的重大問題，肥胖帶來的影響不容忽視。那么在中國，情況是怎樣的呢？值得注意的是我國超重、肥胖患病率的上升速度高于美國，美國的肥胖人口比例在1998年至2006年間增長了37%，我國的肥胖人口比例在1992年至2002年間增長了84%。肥胖問題已經成為我國重要的公共衛生問題。

配合2010廣州亞運開展的“健康亞運健康廣州全民健康活動”，其中一個我們積極倡導的“限鹽限油”項目，也是針對影響健康的這些不利因素。項目中控油壺的推廣，主要目的是讓居民對烹調用油有個量化的概念，逐漸培養適量用油的健康意識，這是個長期的健康教育過程，而對肥胖的預防也應該著眼長期的行為改善。為了人民的健康，對于肥胖的預防和控制，特別是青少年的肥胖問題我們更不容忽視。BMJ - British Medical Journal（《英國醫學雜志》）上面近期發表的一篇關于中小學生肥胖防治的文章，從中我們可以學習一下美國在這方面有關的經驗，啟發我們的工作思路。感興趣的朋友可以到以下鏈接查看：http://www.bmj.com/cgi/content/extract/340/feb23_1/c819

Preventing obesity in primary schoolchildren

中小學生肥胖的防治

作者：Esther M F van Sluijs, Alison McMinn

School based physical activity programmes are promising, but difficult to sustain.

Childhood obesity is rapidly increasing worldwide and is associated with a higher risk of several health problems, as well as with being obese as an adult. Obesity is at least partly caused by an energy imbalance, which makes tackling unhealthy diets and low levels of physical activity in children key public health objectives. Physical activity in childhood has also been independently associated with health outcomes, so promoting physical activity probably has benefits beyond weight control. However, promoting physical activity in children has proved challenging, and we have little evidence available for effective strategies.

In the linked cluster randomised trial on bmj.com (doi:10.1136/bmj.c785), Kriemler and colleagues evaluated a school based physical activity programme targeted at preventing excessive weight gain in Swiss primary schoolchildren. The multi-component intervention was conducted over one school year and focused on three main aspects: increasing the quality and amount of physical education, introducing short daily . . .
