中文摘要：

目的研究肥胖儿童发生血压升高与运动和饮食行为的相关性，旨在探究影响肥胖儿童发生血压升高的不良生活因素。方法采用Cox比例风险模型对124例肥胖儿童进行高血压的运动和饮食行为的分析。结果多因素Cox回归分析结果显示，喜欢吃肉类、甜点、西式快餐、食欲旺盛和学习时间的相对危险度分别为6．658、3．579、2．291、0．528和0．830。结论高脂、高糖饮食，学习时间过长是肥胖儿童早期发生高血压的高危因素。纠正不良饮食、运动行为，可防止肥胖儿童发生高血压，降低心血管疾病的危险。

英文摘要：

[ Objective] To investigate the correlation between hypertension and physical activity, eating behaviors of children with simple obesity, so as to explore the risk factors to hypertension of children with simple obesity. [ Methods ] Cox proportional hazards model was adopted to analyze the hypertension related living risk factors. [ Results] Cox regression analysis showed the relative risk of overeating meat, sweet foods and Western - style fast food, good appetite and long time learning were 6. 658, 3. 579, 2. 291, 0. 528 and 0.830 respectively. [ Conclusion] High-fat and high- sugar diet and long time learning are high risk factors to early hy- pertension of children. Corrected eating habit and exercise behavior can prevent the occurrence of hypertension on children with simple obesity and reduce the risk of cardiovascular disease.
