Shift Work Link to Increased Risk of Heart Problems
Shift workers are slightly more at risk of having a heart attack or stroke than day workers,research suggests.
An analysis of studies involving more than 2 million workers in the British Medical Journal said shift
work can disrupt the body clock and have a negative effect on lifestyle.It has previously been linked to an
increased risk of high blood pressure and diabetes.
Limiting night shifts would help workers cope,experts said.
The team of researchers from Canada and Norway analyzed 34 studies.In total,there were 17,359
coronary events of some kind,including cardiac arrests,6,598 heart attacks and 1,854 strokes caused by
lack of blood to the brain.These events were more common in shift workers than in other people.
The BMJ study calculated that shift work was linked to a 23%increased risk of heart attack,24%
increased risk of coronary event and 5%increased risk of stroke.But they also said shift work was not linked
to increased mortality rates from heart problems and that the relative risks associated with heart problems
were"modest".
Dan Hackam,associate professor at Western University,London, Ontario in Canada,said shift workers
were more prone to sleeping and eating badly."Night shift workers are up all the time and they don't have
a defined rest period.They are in a state of perpetual nervous system activation which is bad for things like
obesity and cholesterol,"he said.
The authors say that screening programs could help identify and treat risk factors for shift workers,such
as high blood pressure and cholesterol levels.They add that shift workers could also be educated about what
symptoms to look out for,which might indicate early heart problems.
Jane White,research and information services manager at the Institution of Occupational Safety and
Health,said there were complex issues surrounding shift work."It can result in disturbed appetite and
digestion,reliance on sedatives and/or stimulants,as well as social and domestic problems."These can
affect performance,increase the likelihood of errors and accidents at work,and even have a negative effect
on health.She said the effects of shift work needed to be well managed.
"Avoiding permanent night shifts,limiting shifts to a maximum of 12 hours and ensuring workers have a
minimum of two full nights'sleep between day and night shifts are simple,practical solutions that can help
people to cope with shift work."

共用题干Most Adults in US Have Low Risk of Heart DiseaseMore than 80 percent of US adults have a less than 10-percent risk of developing heart disease in the next 10 years,according to a report in the Journal of the American College of Cardiology.Just 3 percent have a risk that exceeds 20 percent."I hope that these numbers will give physicians,researchers,health policy analysts,and others a better idea of how coronary heart disease is distributed in the US population,"lead author Dr.Earl S.Ford,from the Centers for Disease Control and Prevention in Atlanta,said in a statement.The findings are based on analysis of data from 13,769 subjects,between 20 and 79 years of age,who narticipated in the Third National Health and Nutrition Examination Survey from 1988 to 1994.Overall,82 percent of adults had a risk of less than 10 percent,15 percent had a risk that fell between 10 to 20 percent,and 3 percent had a risk above 20 percent.The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.By contrast,race or ethnicity had little effect on risk distributions.Although the report suggests that most adults have a low 10-year risk of heart disease,a large proportion have ahigh or immediate risk,Dr.Daniel S.Berman,from Cedars-Sinai Medical Center in Los Angeles,and Dr.Nathan D.Wong,from the University of California at Irvine,note in a related editorial.Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward,they add. The main purpose of the passage is to______.A:introduce that most adults in US adults have low risk of heart diseaseB:give treatment measures to reduce the risk of developing heart disease for US adultsC:describe the research made by the Centers for Disease Control and PreventionD:warn people that they should pay attention to the threat of heart disease immediately
共用题干Napping to a Healthier Heart?1 Researchers say they have developed a simple test that can tell if a person with heart disease is likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people with high levels of this protein are at high risk of heart attack,heart failure or stroke.2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about four years,they studied almost one thousand patients with heart disease.The researchers tested the heart disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more likely than those with the lowest levels to have a heart attack,heart failure or stroke.3 The researchers say the presence of high levels of the protein in the blood shows that the heart muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP were older and had other problems like diabetes or high blood pressure.4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heartdisease patient should affect that person’s treatment.They also would like to know if more aggressive treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in theJournal of the American Medical Association.5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelatedstudy earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries like the United States,afternoon naps are mostly for children. But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in theUnited States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not takenaps.6 The researchers say napping may improve heart health by reducing stress.They say the researchsuggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.If a person has a high level of NT-proBNP_________.A: where fewer pepole die from heart problemB:whether they have the risk of heart attack,heart failure or stroke C:would probably have lower rates of heart diseaseD:how to test a person's NT-proBNP level in the blood by himselfE:his heart muscle would be under pressure in some wayF:that napping is of great benefit to women too

共用题干U.S.Eats Too Much SaltPeople in the United States consume more than twice the recommended amount of salt,raising their risk for high blood pressure,heart attacks and strokes,government health experts said on Thursday.They found nearly 70 percent of U.S.adults are in high-risk groups that would benefit from a lower-salt diet of no more than 1,500 mg per day,yet most consume close to 3,500 mg per day.“It's important for people to eat less salt.People who adopt a heart-healthy eating pattern that includes a diet low in sodium and rich in potassium and calcium can improve their blood pressure,”Dr.Darwin Labarthe of the Centers for Disease Control and Prevention said in a statement."People need to know their recommended daily sodium limit and take action to reduce sodium intake,"Labarthe said.The study in CDC's weekly report on death and disease used national survey data to show that two out of three adults should be consuming no more than 1,500 mg of sodium per day because they are black or over the age of 40-which are considered highrisk groups.Yet studies show most people in the United States eat 3,436 mg of sodium per day,according to a 2005-2006 CDC estimate.Most of the sodium eaten comes from packaged,processed and restaurant foods.The CDC said it will join other agencies in the Health and Human Services department in working with major food manufacturers and chain restaurants to reduce sodium levels in the food supply.Nationwide,16 million men and women have heart disease and 5.8 million are estimated to have had a stroke.Cutting salt consumption can reduce these risks,the CDC said.Too much salt raises one's risk for______.A:high blood pressure B:heart attacksC:strokes D:all of the above

But they are common for adults in Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in theUnited States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three times a week had a thirty-seven percent lower risk of death from heart problems than people who did not takenaps.6 The researchers say napping may improve heart health by reducing stress.They say the researchsuggests that naps are especially good for working men.But they say not enough female subjects died during the study to judge the benefits for women.Paragraph 2 _________A:More Questions to Be AskedB:Older Males Have Higher Levels of NT-proBNPC:Development of a Simple But Important TestD:Evidence of Positive Relationship Between Napping and Heart DiscaseE: How to Control the Levels of NT- proBNPF: Effects of NT-proBNP on Heart Disease
共用题干Most Adults in US Have Low Risk of Heart DiseaseMore than 80 percent of US adults have a less than 10-percent risk of developing heart disease in the next 10 years,according to a report in the Journal of the American College of Cardiology.Just 3 percent have a risk that exceeds 20 percent."I hope that these numbers will give physicians,researchers,health policy analysts,and others a better idea of how coronary heart disease is distributed in the US population,"lead author Dr.Earl S.Ford,from the Centers for Disease Control and Prevention in Atlanta,said in a statement.The findings are based on analysis of data from 13,769 subjects,between 20 and 79 years of age,who narticipated in the Third National Health and Nutrition Examination Survey from 1988 to 1994.Overall,82 percent of adults had a risk of less than 10 percent,15 percent had a risk that fell between 10 to 20 percent,and 3 percent had a risk above 20 percent.The proportion of subjects in the highest risk group increased with advancing age,and men were more likely than women to be in this group.By contrast,race or ethnicity had little effect on risk distributions.Although the report suggests that most adults have a low 10-year risk of heart disease,a large proportion have ahigh or immediate risk,Dr.Daniel S.Berman,from Cedars-Sinai Medical Center in Los Angeles,and Dr.Nathan D.Wong,from the University of California at Irvine,note in a related editorial.Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward,they add. What's the proportion of US adults who have a risk of 10%～20%to develop heart disease? A:More than 80 percent. B:3 percent.C:15 percent. D:20 percent.

共用题干第一篇U. S. Eats Too Much SaltPeople in the United States consume more than twice the recommended amount of salt,raising their risk for high blood pressure,heart attacks and strokes,government health experts said on Thursday.They found nearly 70 percent of U.S.adults are in high-risk groups that would benefit from a lower-salt diet of no more than 1,500 mg per day,yet most consume close to 3,500 mg per day."It's important for people to eat less salt.People who adopt a heart一healthy eating pattern that includes a diet low in sodium（钠）and rich in potassium（钾）and calcium（钙）can improve their blood pressure,"Dr. Darwin Labarthe of the Centers for Disease Control and Prevention(CDC)said in a statement."People need to know their recommended daily sodium limit and take action to reduce sodium intake （摄入量）,"Labarthe said.The study in CDC's weekly report on death and disease used national survey data to show that two out of three adults should be consuming no more than 1,500 mg of sodium per day because they are black or over the age of 40一who are considered as high-risk groups.Yet studies show most people in the United States eat 3,436 mg of sodium per day,according to a 2005- 2006 CDC estimate.Most of the sodium eaten comes from packaged,processed and restaurant foods.The CDC said it will ioin other agencies in the Health and Human Services Department in working with major food manufacturers and chain restaurants to reduce sodium levels in the food supply.Nationwide,1 6 million men and women have heart disease and 5.8 million are estimated to have had a stroke.Cutting salt conoumption can reduce theoe risks，the CDC said.A heart-healthy diet is one that contain_________.A:a low level of sodiumB:a lot of potassium and calciumC:no salt at allD:hoth A and B

共用题干第一篇Shift Work Link to Increased Risk of Heart ProblemsShift workers are slightly more at risk of having a heart attack or stroke than day workers,research suggests.An analysis of studies involving more than 2 million workers in the British Medical Journal said shift work can disrupt the body clock and have a negative effect on lifestyle.It has previously been linked to an increased risk of high blood pressure and diabetes.Limiting night shifts would help workers cope,experts said.The team of researchers from Canada and Norway analyzed 34 studies.In total,there were 17,359 coronary events of some kind,including cardiac arrests,6,598 heart attacks and 1,854 strokes caused by lack of blood to the brain.These events were more common in shift workers than in other people.The BMJ study calculated that shift work was linked to a 23%increased risk of heart attack,24% increased risk of coronary event and 5%increased risk of stroke.But they also said shift work was not linked to increased mortality rates from heart problems and that the relative risks associated with heart problems were"modest".Dan Hackam,associate professor at Western University,London, Ontario in Canada,said shift workers were more prone to sleeping and eating badly."Night shift workers are up all the time and they don't have a defined rest period.They are in a state of perpetual nervous system activation which is bad for things like obesity and cholesterol,"he said.The authors say that screening programs could help identify and treat risk factors for shift workers,such as high blood pressure and cholesterol levels.They add that shift workers could also be educated about what symptoms to look out for,which might indicate early heart problems.Jane White,research and information services manager at the Institution of Occupational Safety and Health,said there were complex issues surrounding shift work."It can result in disturbed appetite and digestion,reliance on sedatives and/or stimulants,as well as social and domestic problems."These can affect performance,increase the likelihood of errors and accidents at work,and even have a negative effect on health.She said the effects of shift work needed to be well managed."Avoiding permanent night shifts,limiting shifts to a maximum of 12 hours and ensuring workers have a minimum of two full nights'sleep between day and night shifts are simple,practical solutions that can help people to cope with shift work."Where can we probably see this article?A:On an issue of newspaper.

问答题Many have come to believe that Type A's are at a much higher risk of suffering heart attack or dying of heart disease than others.
问答题Practice 1 Healthy people with stressful jobs who work long hours but get little satisfaction from what they do have twice the risk of dying from heart disease as satisfied employees, according to a study. Job stress has been known to trigger heart problems in people who already have cardiovascular disease. Now Finnish scientists have now shown that even in healthy people the pressures of work can take their toll. Obesity, high blood pressure, lack of exercise, smoking and being overweight contribute to heart disease — a leading killer in many industrialized countries. But Mika Kivimaki, of the Finnish Institute of Occupational Health, and his colleagues, who studied the medical histories of 812 healthy Finnish men and women in a metal industry company over 25 years, said job stress also plays an important role. Workers who had the highest job-related stress levels at the start of the study were more than twice as likely to die of heart disease, according to the study published in The British Medical Journal. Work stress involves too much work as well as a lack of satisfaction and feeling undervalued and unappreciated. Many people work long hours but if the effort is rewarding the stress is minimized. Kivimaki said job pressure is damaging when being overworked is combined with little or no control, unfair supervision and few career opportunities. The British Heart Foundation said the results support earlier research showing that people in jobs with low control, such as manual workers, could be at greater risk of heart disease than other employees. "It is advisable for people to try to minimize levels of stress at work and for employers to allow people to have more control at work and to be rewarded for their successes," the foundation said in a statement.
