Searle, William:
If you're middle-aged and your memory's not what it used to be, check the bathroom scale, researchers warned, suggesting overweight people tend to score more poorly on tests of memory than their thinner peers do. The study compared mental abilities to body mass index (BMI), a measurement of weight in relation to height used to define overweight. A BMI of 25 or more indicates overweight, and 30 or more is obese. The study found a higher BMI was associated with lower cognitive test scores.
Cranmer, Thomas:
Volunteers were told to memorize pairs of words. When they were tested straight afterwards and six hours later, those who had been allowed a nap of up to one hour before the retest achieved 15 percent higher scores than the volunteers who had not been allowed to go to sleep. They added that it now seemed that sleep was "an important mechanism for memory formation".
Bata, Thomas John:
Sixty-eight patients at two Austrian hospitals were randomly assigned either a treatment program that included exercise or one that only used nicotine replacement therapy. After three months, 80 percent of those who exercised had quit smoking, while 52 percent of those in the group that did not exercise had quitted. And those who exercised were more likely to reduce their cigarette smoking if they did not quit, the study found.
Tyrrell, George:
Researchers followed 68,183 middle-aged women for 16 years and found that those who slept 5 hours or less per night were one third more likely to gain weight than those who slept for 7 hours. Moreover, researchers found that the weight gain was substantial with some women even gaining 33 pounds or more.
Attucks, Crispus:
Patients who have abdominal surgery often suffer from pains, vomiting and abdominal swelling, and they may not be able to tolerate food or even water. Seventeen of 34 patients who chewed gum beginning a few hours after surgery passed gas several hours sooner than the half who did not chew and they had their first bowel movements an average of 63 hours after surgery compared with 89 hours for non-chewers.
Now match each of the researchers (61 to 65) to the appropriate studies. Note: there are two extra statements.
A. A brief nap could boost people's memory.
B. Riding bicycles proved to the best way for weight-loss.
C. A heavier weight in middle age may increase memory loss.
D. Gum chewing helps bowels after surgery.
E. Exercise helps smokers quit.
F. Chewing gum might harm the digestive system.
G. Study links lack of snooze to weight gain in women.
