Prevalence of Obesity and Its Association with Cardiovascular Disease Risk Factors in Adolescent Girls from a College in Central Taiwan

過去研究結果知道肥胖與多種疾病有密切關係，但在臺灣關於青少年女性之肥胖情形與心血管疾病之關係的研究較少。本研究之目的乃研究青少年女性之肥胖與過重的盛行率及其與相關心血管疾病危險因子之關係。研究方法是針對中部某國立大專院校某年全部新生體檢之結果資料，進一步分析研究，這些研究對象分別為15歲年齡層(五專新生)及18歲年齡層（大一新生）。測量項目包括身高、體重、收縮壓、舒張壓、尿酸、膽固醇、三酸甘油脂及高密度脂蛋白。為較清楚表達，我們將肥胖(BMI≥25.3)及過重(22.7≤BMI≤25.2)合併並重定義為過重(BMI≥22.7)的研究結果顯示在291位女生中過重（BMI≥22.7）的盛行率為21.31%，並且發現過重與較高的收縮壓、舒張壓、尿酸值、三酸甘油脂及較低的高密度脂蛋白有相關，具有統計學上明顯的差異。另外發現15歲年齡層女生之尿酸、總膽固醇、三酸甘油脂與高密度脂蛋白之平均值高於18歲年齡層者，且具有統計學上明顯的差異。此外分別有3.1%、15.12%及2.1%的女生其尿酸、總膽固醇及三酸甘油脂值異常過高，而且亦具統計學上顯著差異。另外有5.84%的女生其高密度脂蛋白膽固醇值過低。本研究結果顯示需對於肥胖的青少年女生減重，鼓勵適當的飲食習慣以增加高密度脂蛋白膽固醇的血中濃度，並降低尿酸、低密度脂蛋白膽固醇及三酸甘油脂的血中濃度。

Although obesity is associated with important hemodynamic disturbances, little data exists on population-wide cardiovascular risk factors in obese adolescent girls in Taiwan. This study measured the prevalence of overweight/obesity and related cardiovascular disease risk factors in adolescent females. This was a school-based survey of a representative sample of 291 females aged 15 and 18 years in a public college in Central Taiwan. The main measures were height, body weight, systolic (SBP) and diastolic blood pressure (DBP), uric acid, cholesterol, triglyceride (TG) and high-density lipoprotein cholesterol (HDL-C). Obese (body mass index [BMI]≥25.3) and overweight (22.7≤BMI≤25.2) individuals were combined and labeled as overweight (BMI≥22.7) to make communication of results clearer. Data gleaned from freshmen's health examinations were analyzed. The prevalence of obesity (BMI≥25.3) was 9.28% and of overweight (BMI≥22.7) was 21.31%. Being overweight was associated with higher SBP, DBP, uric acid and TG, and lower levels of HDL-C, but was not associated with cholesterol. The 15-year-old group showed higher mean levels of uric acid, total cholesterol, TG and HDL-C than the 18-year-old group (p＜0.05). All told, 3.1%, 15.12% and 2.1% of the girls showed abnormally elevated levels of uric acid, cholesterol and TG, respectively. In addition, 5.84% had abnormally lower HDL-C levels, indicating that interventions should focus on reducing obesity and encouraging proper dietary habits and sufficient exercise, especially in subjects with lower HDL-C levels and higher levels of cholesterol, TG and uric acid.
