孩童參加體適能計畫 家長也減重


  【24drs.com】根據線上發表於12月18日美國公共衛生期刊的一篇研究,孩童參加以學校為中心、社區為基礎的肥胖預防計畫時,這些家長在2年左右的期間也有適度減重。
  
  疾病控制與預防中心預防效果研究員Edward Coffield博士等人指出,這或許是首度分析測量學校為主之計畫對社區成員健康的影響。研究者在針對1-3年級孩童的計畫(2002-2005年間進行的「桑莫市健身:吃的精明,玩的痛快」)開始與結束時調查了478名家長,調查家長的身高與體重、社經資料、孩童的運動與飲食習慣資訊。參與的家長中,122人有小孩就讀於麻州桑莫市的10所小學,有參與「Shape Up Somerville (SUS)」計畫,另外356人的小孩就讀於桑莫市媒體市場之外的20所小學,作為對照組。
  
  估計治療效果是:與對照組相比,治療組的身體質量指數減少0.411(95%信心區間:減少0.725到減少- 0.097)。
  
  雖然治療效果僅中等,作者們估計,這效果已足以讓治療組家長的平均體重指標從過重降為健康體重,正是美國國家醫學研究院的成年肥胖預防目標之一。
  
  這項計畫還包括:制訂了讓城市適宜行走和適宜騎腳踏車的條例;桑莫市的餐廳提供比較健康的菜單選項;社區報Somerville Journal有固定的SUS專欄;提供附有折價券與食譜的家庭報給參與SUS學校的學生與家長。參與SUS社區的成年人,社區共提供100項SUS社區活動,包括一項健身博覽會。SUS的資料都以桑莫市的四大主要語言(英語、西班牙語、海地-克里奧爾語、葡萄牙語)印刷,每種語言都有家長論壇。
  
  在家長調查中,95.8%的家長表示,他們有時候會或一定會閱讀SUS新聞報,訂閱Somerville Journal的家長中,86.2%表示會閱讀報紙中的SUS文章,超過半數(56.5%)家長表示,因為參與了SUS,外食時會選擇比較健康的選項,將近三分之一(32.2%)的家長表示他們更常採用步行方式。
  
  SUS的主要研究者、麻州波士頓Tufts大學Gerald J.& Dorothy R. Friedman營養科學與政策學院副教授Christina Economos博士在大學新聞稿中表示,我們提供的新證據顯示,社區擴大了學校的預防肥胖計畫的效果,除了原設定為目標的孩童,還影響了家長的體重,因為家長扮演著在家怎麼吃以及如何運動的角色。就公衛觀點,這是相當好的觀察研究。

Parents Lose Weight When Program Targets Children's Fitness

By Jenni Laidman
Medscape Medical News

Parents whose children were part of a school-centered, community-based obesity prevention program reported losing a modest amount of weight over the course of the 2-year intervention, according to a study published online December 18 in the American Journal of Public Health.

The program may be the first to measure the effect of a school-based program on community health, according to Edward Coffield, PhD, prevention effectiveness fellow, Centers for Disease Control and Prevention, Atlanta, Georgia, and colleagues. The researchers surveyed 478 parents at the start and completion of a program targeting children in grades 1 through 3, called Shape Up Somerville: Eat Smart Play Hard, which ran from 2002 to 2005. Parents were asked for their height and weight, socioeconomic data, and information about their child's physical activity and dietary habits. Of participating parents, 122 had children in 10 elementary schools in Somerville, Massachusetts, which participated in Shape Up Somerville (SUS). Another 356 had children in 20 elementary schools in two communities outside the Somerville media market and served as the control group.

The estimated treatment effect was a ?0.411 point reduction in body mass index in the treatment group (95% confidence interval, ?0.725 to ?0.097) compared with control parents.

Although the treatment effect was modest in size, the authors estimate the effect would be enough to reduce mean body mass index of treatment parents from overweight to healthy weight, one of the Institute of Medicine's adult obesity prevention goals.

The program included city walkability and bikeability ordinances; healthier menu options in Somerville restaurants; a regular SUS column in the community newspaper, the Somerville Journal; and a home newsletter with coupons and recipes delivered to parents of children in SUS schools. Adults in the SUS community were exposed to 100 SUS community events, including a fitness fair. SUS materials were printed in Somerville's four dominant languages (English, Spanish, Haitian-Creole, and Portuguese), and parent forums were held in each language.

In a parental survey, 95.8% of parents reported they sometimes or always read the SUS newsletter. Of parents who received the Somerville Journal, 86.2% reported reading SUS articles in the newspaper. More than half of the parents (56.5%) reported choosing healthier options while eating out because of SUS, and almost a third (32.2%) of parents reported they walked more.

"We've provided new evidence that community wide school-based obesity prevention efforts may go beyond the target audience of young children and influence the weight status of their parent, who helps decide what they eat and how active they are at home. From a public health perspective, this is a pretty powerful observation," Christina Economos, PhD, an associate professor at the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy, Tufts University, Boston, Massachusetts, and principal investigator of SUS, said in a university news release.

Funding for this research was provided by a grant from the Centers for Disease Control and Prevention, with additional unrestricted support from Blue Cross Blue Shield of Massachusetts, United Way of Mass Bay, the US Potato Board, Stonyfield Farm, and Dole Foods.
