青少年久坐血压容易偏高
发表日期：2007.2.6
Teenagers who spend a lot of time planted in front of the TV are more likely to have higher blood pressure, regardless of whether they are overweight. "This is the first research to show a direct and independent connection between TV watching and higher blood pressure among adolescents," said study leader Nicolas Stettler, M.D., M.S.C.E., a pediatric nutrition specialist at The Children's Hospital of Philadelphia.
花费大量时间在电视机前的青少年，不管他们是否体重超标血压都更容易偏高。费城儿童医院的儿科营养专家，研究带头人 Nicolas Stettler M.D., M.S.C.E.说“这是揭示青少年看电视和血压偏高间直接而独立联系的第一项研究”。
The team reported on their study of 4,500 American adolescents in the February issue of the Journal of Adolescent Health. They found that sedentary activities and higher body mass index (BMI) were associated with higher systolic blood pressure. Systolic blood pressure is the pressure found when the heart pumps, in contrast to diastolic blood pressure, the pressure between heart beats.
研究小组对4500名美国青少年进行的研究报告发表在青少年健康杂志的周二版上。他们发现，坐式活动和较高的体重指数（BMI）与较高的收缩压联系在一起。收缩压是心脏泵入时的压力，对应心脏搏动间的压力，舒张压。
"It was already known that physical activity lowers blood pressure in both adults and children, but sedentary activity is not just the opposite of physical activity," said Dr. Stettler. "For example, other studies have found that decreasing sedentary activity in young people helps prevent or treat obesity better than interventions to increase physical activity."
Stettler博士说“已知对于成人和儿童体力活动都能降低血压，但是坐式活动不只是与体力活动作用相反”。“例如，其他研究已经发现，减少青少年的坐式活动可以帮助预防或治疗肥胖症，效果比增加体力活动要好。”
If further studies confirm these results, encouraging adolescents to reduce their sedentary activity may improve their blood pressure and lower their later risk of cardiovascular disease and stroke.
如果进一步的研究证实了这些结果，鼓励青少年减少他们的坐式活动可能会改善他们的血压并降低他们以后发生心血管疾病和中风的风险。
The researchers studied nationally representative data from 4,500 U.S. adolescents, aged 12 to 19, who participated in the 1999-2002 National Health and Nutrition Examination Survey. Interviewers assessed the adolescents' nutritional intake and activities. Measurements of blood pressure and BMI were adjusted for gender and age.
研究人员对4500名美国青少年的全国代表性数据进行了研究，年龄在12到19岁间，他们在1999-2002年的国家健康与营养调查研究时加入。交谈者评估青少年的营养摄入和活动情况。根据性别和年龄对血压和BMI的测量结果进行了修正。
Within the 12- to 15-year-old age group, the study team found higher blood pressure to be especially associated with higher levels of watching television and video. "Although the association between sedentary activity and systolic blood pressure was rather small, most adolescents spend several hours per day in sedentary activities," said Yasuki Kobayashi, M.D., Ph.D., of the University of Tokyo Department of Public Health, a co-author on this study. "Interventions to decrease sedentary activities may have an important public health impact."
在12到15岁年龄组，研究小组发现了尤其与看较多电视和录像有关的血压较高。东京大学公共卫生教研室，此项研究的合作者Yasuki Kobayashi, M.D. Ph.D.说“虽然在坐式活动和收缩压间的联系相当小，但是大部分的青少年每天花费几个小时进行坐式活动”。“通过减少坐式活动可能对公共健康有重大的影响。”
"Elevated blood pressure is one of the most important risk factors for cardiovascular diseases and stroke," said Mr. Takehiro Sugiyama, a medical student at the University of Tokyo and first author on this study. "High blood pressure in adolescents is predictive of hypertension in adulthood, and in addition, adolescent obesity is a predictor or obesity and cardiovascular risk factors in young adulthood and beyond."
东京大学的医学生及此项研究的首作者Takehiro Sugiyama先生说“血压升高是心血管疾病和中风发作的很多重要风险因素之一”。“青少年的高血压是预示着成人时期的高血压，另外，青少年时期的肥胖是成人期及之后肥胖和心血管风险的一个预报器或者影响因素。”
The researchers also found that higher BMI is associated with lower diastolic blood pressure, contrary to associations found previously in studies of adults. The implications of this finding are unclear, but shows that adolescents are not just "small adults" and may have determinants of blood pressure that are different from adults said the authors.
