Background
Television viewing is strongly associated with an increased risk of childhood and adolescent obesity. However, the association between TV viewing and hypertension in children is unknown. This study aimed to identify whether TV watching is associated with hypertension in obese children.
Methods
Children seen for obesity, aged 4 to 17 years, were evaluated at three pediatric centers from 2003 to 2005. In 2006–2007, a logistic regression model estimated the odds of hypertension for hours of daily TV time controlling for race, site, and body mass index (BMI) z-score.
Results
A total of 546 subjects, with a mean age of 12 years, were evaluated. The children had a mean BMI of 35.5±9.3 kg/m2 (98.7th±0.8 percentile, z-score 2.54±0.4). TV time was positively correlated with the severity of obesity. After controlling for race, site, and BMI z-score, both the severity of obesity and daily TV time were significant independent predictors of the presence of hypertension. Children watching 2 to 4 hours of TV had 2.5 times the odds of hypertension compared with children watching 0 to <2 hours. The odds of hypertension for children watching 4 or more hours of TV were 3.3 times greater than for children watching 0 to <2 hours of TV.
Conclusions
In obese children, the amount of time spent watching TV is associated with both hypertension and the severity of obesity. Thus, TV viewing is a potential target for addressing hypertension in obese children.

肥胖儿童看电视与高血压的关系
Background
Television viewing is strongly associated with an increased risk of childhood and adolescent obesity. However, the association between TV viewing and hypertension in children is unknown. This study aimed to identify whether TV watching is associated with hypertension in obese children.
背景：看电视与儿童和青少年肥胖有密切的关系。但是，儿童看电视与高血压的关系尚不清楚。这项研究的旨在明确肥胖儿童看电视与高血压是否相关。
Methods
Children seen for obesity, aged 4 to 17 years, were evaluated at three pediatric centers from 2003 to 2005. In 2006–2007, a logistic regression model estimated the odds of hypertension for hours of daily TV time controlling for race, site, and body mass index (BMI) z-score.
方法：2003年-2005年间，4-17岁的肥胖儿童在3个儿科中心接受检查。2006年-2007年，采用logistic回归模型分析高血压危险与每天看电视时间的关系，同时控制民族，地区和体重指数Z－score。
Results
A total of 546 subjects, with a mean age of 12 years, were evaluated. The children had a mean BMI of 35.5±9.3 kg/m2 (98.7th±0.8 percentile, z-score 2.54±0.4). TV time was positively correlated with the severity of obesity. After controlling for race, site, and BMI z-score, both the severity of obesity and daily TV time were significant independent predictors of the presence of hypertension. Children watching 2 to 4 hours of TV had 2.5 times the odds of hypertension compared with children watching 0 to <2 hours. The odds of hypertension for children watching 4 or more hours of TV were 3.3 times greater than for children watching 0 to <2 hours of TV.
结果：546名儿童接受了检查，平均年龄12岁。这些儿童平均体重指数为 35.5±9.3 kg/m2（98.7±0.8 百分位数，Z-score 2.54±0.4）。看电视时间与肥胖的严重程度呈正相关。控制了民族、地区和体重指数Z-score之后，肥胖的严重程度和每天看电视时间是发生高血压的显著独立危险因子。每天看电视2-4小时的儿童发生高血压的危险是每天看电视少于2小时的儿童的2.5倍。每天看电视超过4小时的儿童发生高血压的危险是每天看电视少于2小时的儿童的3.3倍。
