[[alternative]]The Effects of Body Weight Control Intervention on Metabolic Syndrome: A Preliminary Study in a Junior High School-Running Title: Metabolic Syndrome with Body Weight Control

[[abstract]]目的：旨在探討青少年體重控制做為介入策略對於代謝症候群防治之成效。方法：採前後測對照組之類實驗性研究設計。共有36位國民中學七年級學生參與本研究，實驗組、對照組各有18人。介入為期六個月；內容包括與體重控制有關的活動和飲食，策略則以強化認知及增加體能活動作為介入之徑路。結果：本研究假設獲得證實的有二：(1)實驗組學生介入後，腰圍減小(1.6±1.9cm)、舒張壓下降(4.8±8.6mmHg)；(2)實驗組學生的收縮血壓明顯下降（達11-29mmHg）的人數百分比顯著高於對照組，且舒張壓下降的平均值(4.8±8.6mmHg) 也明顯優於對照組(2.6±5.7mmHg)。但與研究假設不一致的是，實驗組學生介入前後的體重改變雖達到顯著差異(p=0.009)，但體重並非降低，而是平均增加1.9±2.8公斤。其他研究假設則未能在本研究中獲得証實。結論：本研究藉由體重控制介入降低了腰圍及血壓，顯示這對於高危險群的青少年預防代謝性症候群的價值是肯定的；但由於運動介入的頻率與時間長度的不足加上青少年的快速生長特質，影響介入成效，在本文中將進一步討論並提出日後研究的建議。[[abstract]]Purpose: The aim of this study is to examine the effects of body weight control programs on metabolic syndrome for adolescents. Methods: The pretest-posttest control group of quasi-experimental was designed. The study consisted of 36 seventh grade students in junior high school that the experimental and the control groups were 18 students in each group. The interventional programs included regular exercises and dietary educations. The strategies were increased the dietary knowledge and physical activities. Results: The hypotheses were proved. The results of the study were that the experimental group's circumferences of waist were reduced, and the systolic pressure and the diastolic pressure were also reduced significantly. Unfortunately, the hypothesis was not able to match the goals of the intervention since the experimental group had raised the body weight to 1.9±2.8kg for average. Conclusions: This study had the positive value. By controlling of body weight reduce blood pressure and circumference of waist in the high risk students of the metabolic syndrome. The limitations of this study were the maturation of the students and lacked regular exercises. The suggestions will be provided for further research
