It is summer now and thought a suntan we get vitamin D. This vitamin plays a key role in bone and muscle health, and a deficiency can lead to reduced bone density, muscle weakness, osteoporosis and broken bones. However, there are a little percentage of tanned people among the seniors.
So in was calculated that about 90 percent of older people are vitamin D-deficient. Also a study reviled that vitamin D deficiency some how connected with physical activity of the person. The study included more than 1000 people, aged 55 to 88 who were under doctor's control for six years. Participants' vitamin D levels were checked and they were asked about their ability to do routine tasks. Among participants aged 65 to 88, those with the lowest vitamin D levels were likely to have at least one physical limitation as those with the highest vitamin D levels. Among participants aged 55 to 65, those with the lowest vitamin D levels were twice as likely to have at least one physical limitation as those with the highest vitamin D levels.
The findings indicate low vitamin D levels in older individuals may contribute to the declining ability to live independently. While the study found an association between low vitamin D levels and limited mobility, it did not establish a cause-and-effect relationship.
