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.
The new study conducted by Dr. Sacco and his colleagues is unique in that ______.
选项
A、it refutes early studies on the protective effect of moderate drinking against heart attacks
B、it confirms early studies of moderate drinking against heart attacks
C、it helps to resolve the disputes over the effect of moderate drinking against strokes
D、it finds that moderate drinking can benefit people of different races equally well
答案
C
解析
推理判断题。根据文章第三段第一句话:适量饮酒可以预防心脏病,这已是大家完全确认的事实,但是酒与中风的关系,在数据上一直存在冲突。可见论文不是讨论酒与心脏病的关系,所以排除A 和B ;第二句话指出这项研究解决了这一问题,所以正确答案为C ,选项D 是干扰项,第三段第二句话后半部分说,这项研究对黑人、拉美人和白人同样有效,可能会误导我们认为对所有种族有效,但是可以根据第三段最后一句话予以排除:还需要对亚洲人做进一步研究,以确认适量饮酒是否在他们身上有效。
