According to a new research, old people with not enough Vitamin D in their bodies are likely to face problems in mobility and become disabled.
Vitamin D is very important for strength of bones and sunlight is one of the major sources of this component of nutrition. People in old age often limit themselves to indoor activities and therefore do not get exposure to sunlight. They usually have other health problems as well and this limitation in their physical activity adds to their health issues.
The recent study focuses on this aspect to highlight the problem and encourage the researchers for further research on the topic. "This is one of the first studies to look at the association of vitamin D and the onset of new mobility limitations or disability in older adults," lead study author Denise Houston, a nutrition epidemiologist in the Wake Forest Baptist Department of Geriatrics and Gerontology, said regarding the research, as reported on sciencedaily.com.
The sample for the study consisted of male and female participants, whose ages were within the range of 70 to 79 years. They were observed over a period and noted for mobility issues and other health problems. "We observed about a 30 percent increased risk of mobility limitations for those older adults who had low levels of vitamin D, and almost a two-fold higher risk of mobility disability. It's difficult to get enough vitamin D through diet alone and older adults, who may not spend much time outdoors, may need to take a vitamin D supplement," Houston said, as reported by the sciencedaily.com report.
Experts say that muscle performance deteriorates as a result of deficiency of Vitamin D. The deficiency also accelerates other diseases like heart problems, diabetes etc. to some extent. So it needs to be taken seriously and managed through proper diet and supplements if required.
The study is a starting point for further investigations into the subject and developing remedies for the problems arising because of the lack of Vitamin D. "Higher amounts of vitamin D may be needed for the preservation of muscle strength and physical function as well as other health conditions. However, clinical trials are needed to determine whether increasing vitamin D levels through diet or supplements has an effect on physical function," Houston further said.
