Millions of Americans have lost their jobs because of the present recession (经济衰退). A new study shows that losing your job can bring some health problems. It is bad for your heart, your blood pressure and so on.

Earlier studies have shown that health has something to do with job loss. But it was not sure whether job loss made health poor, or poor health led to job loss. The new study tried to discover the answer to this.

Kate Strully worked on the study while she was at the Harvard School of Public Health. Ms Strully is now a scientist at the State University of New York. She had some information about the income (收入) of some people.

She asked people all over the country some questions about their health and work. Ms Strully checked the information about more than eight thousand people. She collected the information, and then looked at their health some time later. She found out that 80% of people didn't have health problems before they lost their jobs. But now they have a new health problem after losing their jobs.
