Study confirms that moderate drinking reduces stroke risk. Similar to the way a drink or two a day protects against heart attacks, moderate alcohol consumption wards off strokes, a new study found.
The study also found that the type of alcohol consumed—beer, wine or liquor-was unimportant. Any of them, or a combination was protective, researchers reported in today’s Journal of the American Medical Association. "No study has shown benefit in recommending alcohol to those who do not drink", cautioned the authors, led by Dr. Ralph L. Sacco of Columbia University College of Physicians and Surgeons in New York. But the new data support the guidelines of the National Stroke Association, which say moderate drinkers may protect themselves from strokes by continuing to consume alcohol, the authors said.
The protective effect of moderate drinking against heart attacks is well established, but the data had been conflicting about alcohol and strokes, the authors said. The new study helps settle the question and is the first to find blacks and Hispanics benefit as well as whites, according to the authors. Further research is needed among other groups, such as Asian, whom past study suggested may get no stroke protection from alcohol or may even be put at greater risk.
Among the groups where the protective effect exists, its mechanism appears to differ from the protective effect against heart attacks, which occurs through boosts in levels of so-called "good" cholesterol, the authors said. They speculated alcohol might protect against stroke by acting on some other blood trait, such as the tendency of blood platelets to clump, which is key in forming the blood clots that can cause strokes.
The researchers studied 677 New York residents who lived in the northern part of Manhattan and had strokes between July 1,1993 and June, 1997. After taking into account differences in other factors that could affect stroke risk, such as high blood pressure, the researchers estimated that subjects who consumed up to two alcoholic drinks daily were only half as likely to have suffered clot-type strokes as nondrinkers. Clot-type strokes account for 80 percent of all strokes, a leading cause of the US deaths and disability. Stroke risk increased with heavier drinking. At seven drinks per day, risk was almost triple that of moderate drinkers.
An expert spokesman for the American Heart Association, who was not involved in the study, said it was well-done and important information. But it shouldn’t be interpreted to mean, "I can have two drinks and therefore not worry about my high blood pressure or worry about my cholesterol," said Dr. Edgar J. Kenton, an associate professor of clinical neurology at Thomas Jefferson University Medical College in Philadelphia. Instead, he said, the study provides good reason to do further research and to add alcohol to the list of modifiable risk factors for stroke.
What is said in the last paragraph by Dr. Kenton indicates that ______.
选项
A、he is in serious doubt about the validity of the study
B、drinking alone can not protect against strokes
C、people should add alcohol to their daily diet
D、the study has not built a link between drinking and high blood pressure
答案
B
解析
推理判断题。根据文章最后一段第二句话:Dr. Kenton警告说(尽管这项研究意义重大)但不要认为:喝两杯酒就可以不用担心高血压或胆固醇了。这暗含了仅仅靠喝酒不能根本解决问题,也表明中风跟高血压是有关系的,这也在文章第五段第二句话... other factors that could affect stroke risk, such as high blood pressure...得到了证实,所以排除选项D ,而选择B 。根据最后一句话,Kenton说这项研究为进一步研究指明了方向,为将酒列为减少中风因素提供了很好的理由,所以排除A 。
