摘要

背景：肥胖對台灣兒童來說已形成一個值得重視的健康問題，並且是糖尿病和心血管疾病的危險因子；本研究的目的是評估施行十二週的心臟健康衛教和體能活動，對體重、糖尿病、以及心血管疾病危險因子的影響。
方法：研究對象包括120位肥胖國小五年級生（65位男生，55位女生，年齡10-13歲（平均10.6歲），身體質量指數(BMI)是95 percentile或以上），被隨機分配為介入組(n=60)或控制組(n=60)。介入組接受十二週的心臟健康衛教和體能活動，而控制組沒有。兩組肥胖兒童於研究前後都接受一系列檢查，包括身高、體重，BMI、體脂肪比例、血壓、體適能測試（八百公尺跑步時間）、心臟健康知識，血清生化檢查。統計分析兩組肥胖兒童的研究前後資料，以比較其差異性。
結果：研究結果顯示兩組肥胖兒童於研究後，有顯著差異的項目是體重(P=0.024)、BMI(P=0.047)、體脂肪比例(P=0.008)、八百公尺跑步時間(P=0.025)、心臟健康知識(P=0.006)，總膽固醇(P=0.027)、三酸甘油脂(P=0.018)，高密度脂蛋白膽固醇(P=0.009)、低密度脂蛋白膽固醇(P=0.041)、血糖(P=0.035)、胰島素(P=0.007)、胰島素抵抗力(HOMA-IR)(P=0.028)。介入組於研究後，體重、BMI、體脂肪比例、總膽固醇、三酸甘油脂、低密度脂蛋白膽固醇、血糖、胰島素和HOMA-IR下降，而高密度脂蛋白膽固醇上升。
結論：本研究的結論是以班級為基礎，施行心臟健康衛教和體能活動課程的體重控制介入，有助於促進兒童心血管的健康，這個方法對國小學生是簡單、實用、且有益。

Background: Childhood obesity has become a growing public health issue in Taiwan. Obese children have risk factors for type 2 diabetes and cardiovascular disease. In this prospective study, we investigated the effect of a twelve-week heart health education and physical activity program on body weight and risk factors for type 2 diabetes and cardiovascular disease.
Methods: Subjects were 120 obese fifth graders (65 boys and 55 girls, aged 10-13 years (mean 10.6 yrs), body mass index (BMI) at the 95th percentile or more) and were randomly assigned to an intervention group (n=60) or control group (n=60). The intervention group received a twelve-week heart health education and physical activity program, while the control group did not. In both groups, a series of examinations were done at baseline and post-test, including height, weight, BMI, body fat, blood pressure (BP), physical fitness (800-meter running test), heart health knowledge, and serum biochemistry. Differences for baseline and post-test data were compared between both groups.
Results: Mean changes in the intervention group versus control group were significant for weight (P=0.024), BMI (P=0.047), percentage body fat (P=0.008), physical fitness (800-meter running test) (P=0.025), heart health knowledge (P=0.006), total cholesterol (P=0.027), triglycerides (P=0.018), high-density lipoprotein cholesterol (HDL-C) (P=0.009), low-density lipoprotein cholesterol (LDL-C) (P=0.041), sugar (P=0.035), insulin (P=0.007), and insulin resistance (HOMA-IR) (P=0.028). At post-test, weight, BMI, body fat, total cholesterol, triglycerides, LDL-C, sugar, insulin and HOMA-IR had decreased, but HDL-C had increased in the intervention group.
Conclusions: A classroom-based weight-control intervention provides educational programs to promote cardiovascular health in children. This intervention is simple, practical, and beneficial for elementary school children.
