People with chronic physical diseases such as angina, arthritis, asthma and diabetes also fare far worse if they also suffer from depression, the team of international researchers found.

They found that 3.2 percent of people had experienced a depressive episode in the past year. For people with angina, the rate was 4.5 percent; for people with arthritis, it was 4.1 percent; for those with asthma, it was 3.3 percent; and for people with diabetes, it was 2 percent.
Moreover, between 9 percent and 23 percent of people had depression in addition to suffering from one or more of these conditions. That's significantly higher than the likelihood of having depression without having a chronic disease, Chatterji's group noted.
After the researchers had accounted for socioeconomic factors and health conditions, they confirmed that depression had the biggest effect on worsening health compared with the other four major chronic illnesses. In different countries, people with depression plus one or more chroni
