Hearing Loss May Increase Depression Risk
People who lose their hearing are more likely than others to become depressed, a new study suggests. Researchers looked at data from a U.S. government health survey of 18,000 adults. Those who were 70 and older received hearing tests. The others were asked about their hearing and any problems with it. Everyone also filled out a questionnaire designed to show if they were depressed. About 5% of those with no hearing problems and 11% of those with some degree of hearing loss were depressed. Depression with hearing loss was most common among those under age 70. Women had higher rates of depression than men. Depression was also more likely as hearing loss grew worse. But those who were totally deaf were not more likely to be depressed. Researchers said they may have become used to coping with a lack of hearing.
Study: Prostate Surgery Boosts Survival
Men with prostate cancer may live longer if they have surgery rather than "watchful waiting," a long-term study suggests. The benefit was strongest for younger men and those with medium-risk tumors. At the time the study began, the PSA test was not widely used. Most men were diagnosed because they had symptoms or a lump in the prostate. The study included nearly 700 Swedish men with prostate cancer. They were randomly assigned to receive prostatectomy (removal of the prostate) or no immediate treatment. In the next 23 years, 56% of the men in the surgery group and 69% in the watchful-waiting group died. Prostate cancer was the cause of death for 18% of the surgery group and 29% of the other group. Men in the surgery group also were less likely to have their cancer spread or to need anti-hormone treatments. The most benefit occurred among men who were under age 65 when diagnosed.
Age May Alter Cancer-Death Risk from Meat
Eating more meat in middle age may increase people's risk of death, particularly from cancer, a new study finds. But older adults who ate more protein lived longer than those who ate less. The study was based on diet surveys from more than 6,800 adults. Researchers kept track of deaths during the next 18 years. People were divided into 2 groups: middle aged (50-65) or older (over 65). Diets with at least 20% of calories from protein were classified as high-protein. Middle-aged people with high-protein diets were 75% more likely to die during the study period than those with low-protein diets (less than 10% of calories). They were 4 times as likely to die of cancer. Cancer-death risk was 3 times as high in the moderate-protein group (10% to 19% of calories). Most protein came from meat and dairy products.
