To examine the prevalence of childhood and adolescent obesity in Taiwan and investigate the association between excess weight and physical fitness and blood pressure.
Cross-sectional study.
A total of 13 935 children and adolescents aged 6-18 years (boys: 7031, girls: 6904) were involved in the 1999 survey and 24 586 (boys: 12 367, girls: 12 219) were available in the 2001 survey.
Weight, height, systolic and diastolic blood pressures, and health-related fitness tests (bent-leg curl-ups, sit-and-reach test and step test) were measured.
The overall prevalence of obesity (including overweight) in boys was 19.8% in 1999 and 26.8% in 2001. It was lower in girls with 15.2% in 1999 and 16.5% in 2001. The normal weight group performed better (P<0.05) than the overweight/obese group in all fitness tests except in the 2001 sit-and-reach test where there were no differences between the two groups. The risk of hypertension increased nearly two times for the overweight/obese-fit group and nearly three times for the overweight/obese-unfit group compared to the normal weight-fit group (adjusted odds ratio (AOR)=1.93, 95%CI=1.514-2.451 and AOR=2.93, 95%CI=2.493-3.454, respectively).
Overall, the findings demonstrated that there is an increasing trend in overweight/obesity prevalence for Taiwanese youth even in a 2-year period. The overweight/obese youngsters tend to have poorer muscular strength and cardiovascular endurance than the normal weight group. The overweight/obese and unfit group had a greater risk of hypertension than other groups. However, this risk was significantly lower if obese/overweight children had a higher than average level of cardiovascular fitness.
调查台湾儿童及青少年肥胖症的患病率，并研究超重与身体素质及血压之间的关联。
横断面研究。
1999年的调查纳入了13935名6至18岁的儿童及青少年（男孩7031名，女孩6904名），2001年的调查中有24586名（男孩12367名，女孩12219名）。
测量体重、身高、收缩压和舒张压，以及与健康相关的体能测试（屈膝仰卧起坐、坐位体前屈测试和台阶测试）。
1999年男孩肥胖（包括超重）的总体患病率为19.8%，2001年为26.8%。女孩患病率较低，1999年为15.2%，2001年为16.5%。在所有体能测试中，正常体重组的表现均优于超重/肥胖组（P<0.05），但在2001年的坐位体前屈测试中，两组之间没有差异。与正常体重且体能良好组相比，超重/肥胖且体能良好组患高血压的风险增加了近两倍，超重/肥胖且体能不佳组患高血压的风险增加了近三倍（调整后的优势比（AOR）分别为1.93，95%置信区间=1.514 - 2.451和AOR = 2.93，95%置信区间=2.493 - 3.454）。
总体而言，研究结果表明，即使在两年时间内，台湾青少年超重/肥胖的患病率也呈上升趋势。超重/肥胖的青少年往往比正常体重组的肌肉力量和心血管耐力更差。超重/肥胖且体能不佳的组患高血压的风险比其他组更大。然而，如果肥胖/超重儿童的心血管健康水平高于平均水平，这种风险会显著降低。
