WHO Focuses on Aging Population for World Health Day

By |March 12, 2012|Research|

Between 2000 and 2050, the proportion of the world’s population over 60 years will double from about 11 percent to 22 percent.

One of the biggest social transformations is population aging. Soon, the world will have more older people than children and more people of very old age than ever before. The World Health Organization is focusing on aging and health for World Health Day on April 7.

The world will have more people who live to see their 80s or 90s than ever before. The number of people aged 80 years or older, for example, will have almost quadrupled to 395 million between 2000 and 2050. There is no historical precedent for a majority of middle-aged and older adults having living parents, as is already the case today. More children will know their grandparents and even their great-grandparents.

With that in mind Chiropractic and Manual Therapy has just published the first paper in a thematic series on chiropractic care in older adults. This thematic series provides an overview of current best evidence in key aspects of evaluation and management of chiropractic care for older adults. Individual articles address the magnitude of musculo-skeletal problems in the elderly population, diagnostic challenges for chiropractors and other manual therapists seeing elderly patients, the evidence for chiropractic and manual therapy in the care of the elderly and also imaging modalities for musculo-skeletal disorders in the elderly including utility, validity and cost.

Nutrition: 4 Vitamins That Strengthen Older Brains

Higher blood levels of omega-3 fatty acids, vitamin B, vitamin C, vitamin D and vitamin E are associated with better mental functioning in the elderly, a new study has found.

Researchers measured blood levels of these nutrients in 104 men and women, whose average age was 87. The scientists also performed brain scans to determine brain volume and administered six commonly used tests of mental functioning. The study is in the Jan. 24 issue of Neurology.

After controlling for age, sex, blood pressure, body mass index and other factors, the researchers found that people with the highest blood levels of the four vitamins scored higher on the cognitive tests and had larger brain volume than those with the lowest levels.

Omega-3 levels were linked to better cognitive functioning and to healthier blood vessels in the brain, but not to higher brain volume, which suggests that these beneficial fats may improve cognition by a different means.

Higher blood levels of trans fats, on the other hand, were significantly associated with impaired mental ability and smaller brain volume.

The lead author, Gene L. Bowman, a researcher in neurology at Oregon Health and Science University, said that the study could not determine whether taking supplements of these nutrients would decrease the risk for dementia. But he added: “What’s the harm in eating healthier? Fish, fruits, vegetables all have these nutrients, and staying away from trans fats is one key thing you can do.”
