【medical-news】脂肪多的人中风后死亡率较低
NEW YORK (Reuters Health) Mar 17 - Obese and overweight individuals are less likely to die after a stroke than are their normal-weight peers, new research suggests.
According to the authors, the link between obesity and poor disease outcomes, in general, is usually mediated through the presence of other conditions. Obese individuals who are otherwise healthy may fare just as well as, or perhaps in the case of stroke, better than their lean counterparts.
The findings, which are reported in the February 29th online issue of Neuroepidemiology, are based on an analysis of data from 21,884 stroke patients in Denmark who had their body mass index determined. The subjects were followed for up to 5 years after their stroke.
The patients were placed into one of five BMI groups: underweight (BMI < 18.5), normal weight (18.5 to 24.9), overweight (25.0 to 29.9), obese (30.0 to 34.9), and severely obese (35 and greater).
Compared with the normal weight individuals, the overweight, obese and severely obese subjects were 27%, 16%, and 16% less likely, respectively, to die during follow-up, lead author Dr. Tom Skyhoj Olsen, from Hvidovre University Hospital and colleagues note.
Underweight patients, by contrast, were 63% more likely to die, the report indicates.
High BMI remained a predictor of post-stroke survival, independent of sex, age, civil status, stroke severity, stroke subtype and risk factors.
"Recently, the use of BMI as a risk factor marker in primary and secondary prevention of cardiovascular disease has been questioned," the authors state. "The result of our study lends support to the suggestion from (prior) studies of a redefinition of overweight and obesity, for example by the waist-to-hip ratio."

脂肪多的人中风后死亡率较低
NEW YORK (Reuters Health) Mar 17 - Obese and overweight individuals are less likely to die after a stroke than are their normal-weight peers, new research suggests.
纽约（路透社-健康）：新的研究表明，肥胖和过高体重的人与正常体重的同龄人相比，中风后死亡的可能性小得多。
According to the authors, the link between obesity and poor disease outcomes, in general, is usually mediated through the presence of other conditions. Obese individuals who are otherwise healthy may fare just as well as, or perhaps in the case of stroke, better than their lean counterparts.
作者提到，一般来说，肥胖和疾病不良结局的联系通常受到其他因素的影响。在中风这个问题上，那些肥胖而健康的人与那些体型瘦小的比较对象相比，发病情况可能差不多，甚至可能更少。
The findings, which are reported in the February 29th online issue of Neuroepidemiology, are based on an analysis of data from 21,884 stroke patients in Denmark who had their body mass index determined. The subjects were followed for up to 5 years after their stroke.
这个研究结果发表在《神经流行病学》二月份第29期的网络版上，该研究的结果基于对丹麦21884位中风病人的数据分析，并且这些病人的BMI(体重指数)是已经确定的。在他们中风后，研究者对他们随访了5年。
The patients were placed into one of five BMI groups: underweight (BMI < 18.5), normal weight (18.5 to 24.9), overweight (25.0 to 29.9), obese (30.0 to 34.9), and severely obese (35 and greater).
根据病人的BMI水平，他们被分为5组：过低体重组(BMI < 18.5)，正常体重组(18.5 to 24.9)，过高体重组(25.0 to 29.9)，肥胖组(30.0 to 34.9)，和极度肥胖组(35 and greater).
Compared with the normal weight individuals, the overweight, obese and severely obese subjects were 27%, 16%, and 16% less likely, respectively, to die during follow-up, lead author Dr. Tom Skyhoj Olsen, from Hvidovre University Hospital and colleagues note.
来自Hvidovre大学附属医院的主要负责人Tom Skyhoj Olsen医生和他的同事说到，过高体重组、肥胖组和极度肥胖组的研究对象分别与正常体重组研究对象相比，在随访期间死亡的可能性降低了27%, 16%, and 16%。
Underweight patients, by contrast, were 63% more likely to die, the report indicates.
研究显示，相反地，过低体重组的病人与正常体重组病人相比，在随访期间死亡的可能性要高63%。
High BMI remained a predictor of post-stroke survival, independent of sex, age, civil status, stroke severity, stroke subtype and risk factors.
高BMI仍然作为独立于性别、年龄、社会地位、中风严重性、中风亚型的预测中风后生存时间的危险因素之一。
