WASHINGTON — Knee pain from osteoarthritis (OA), which damages the quality of life, can in turn lead to depression, according to a new Japanese study.
The study, published in the Journal of the American Geriatrics Society, found that among non-depressed older adults with osteoarthritis knee pain, nearly 12 percent will go on to develop symptoms of depression within two years.
To learn more, the researchers examined information from 573 people aged 65 or older who participated in the Kurabuchi Study, an ongoing look at the health of older adults living in central Japan.
Participants at greatest risk for depression include those who experience knee pain while lying in bed at night, while putting on socks, or while getting in or out of a car.
When the study began (between 2005 and 2006) none of the participants had symptoms of depression. Two years later, nearly all of them completed follow-up interviews. The participants answered questions about their knee pain and were evaluated for symptoms of depression.
Nearly 12 percent of the participants had developed symptoms of depression. People who experienced knee pain at night while in bed, while putting on socks, or while getting in or out of a car were more likely to report having symptoms of depression, noted the researchers.
The researchers concluded that asking older adults with knee pain whether they have pain at night in bed, when putting on socks, or while getting in or out of a car could be useful for helping to screen people at risk for developing depression.

Regular bedtime beneficial for heart and metabolic health among older adults
KATHMANDU — Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But a new study on sleep patterns has suggested that a regular bedtime and wake time are just as important for heart and metabolic health among older adults too.
Researchers at Duke Health and the Duke Clinical Research Institute, in a study of 1,978 older adults, have found that people with irregular sleep patterns weighed more, had higher blood sugar, higher blood pressure, and a higher projected risk of having a heart attack or stroke within 10 years than those who slept and woke at the same times every day.
The study was published Sept 21 in the journal Scientific Reports.
“From our study, we can’t conclude that sleep irregularity results in health risks, or whether health conditions affect sleep,” said study’s lead author Jessica Lunsford-Avery.
“Perhaps all of these things are impacting each other.”
African-Americans had the most irregular sleep patterns compared to participants who were white, Chinese-American or Hispanic, the data showed.
Still, the data suggest tracking sleep regularity could help identify people at risk of disease, and where health disparities may impact specific groups.
Irregular sleepers were also more likely to report depression and stress than regular sleepers, both of which are tied to heart health.Follow @gorkhapost
