A new study conducted among 110,000 American adults has once again shown several factors that are associated with a greatly increased risk of death and disability from heart disease. (1) _______________________________________.Men who are classified as "most active" showed no advantage in terms of heart attack rate over men considered "moderately active". Men who are "least active", both on and off the job, are twice as likely as "moderately active" men to suffer a first heart attack.(2) _________________________________________, such as the amount they smoke, could account for their different heart attack rates.The heavier men in the study had a fifty percent greater risk of suffering a first heart attack than the lighter-weight men. (3) ________________________________. None of the differences in risk could be explained on the basis of variations in exercise habits.The incidence of heart attacks was also found to be higher among white men than among non-whites and among Jewish men than among Christians. But the heart attack rate among Jewish women was not markedly different from that among non-Jewish women.
1. The study reported that men and women who smoke cigarettes face twice the risk of suffering a first heart attack as do non-smokers
2. The study didn't show that other differences between active and inactive men
3. An increased risk was also found among women who had gained a lot of weight since age 25
1)The study reported that men and women who smoke cigarettes face twice the rest suffering a first heart attack as do not smokers
2)The study didn't show that other differences between accident and inact men
3)And increase risk could also find among women who gain a lot of way sends eight to twenty five
