A new study shows that older people with vitamin D deficiency may struggle with daily physical activities such as climbing stairs or dressing. It’s estimated that as many as 90 percent of older people are vitamin D-deficient. The vitamin, usually absorbed through diet or sunlight, plays a key role in bone and muscle health, and a deficiency can lead to muscle weakness, reduced bone density, broken bones and osteoporosis.
The study included more than 1,300 people, aged 55 to 88 who were followed for six years. Their vitamin D levels were checked and they were asked about their ability to do regular or everyday tasks, such as sitting down and standing up from a chair or walking outside for five minutes without resting.
Among participants aged 65 to 88, those having the lowest vitamin D levels were 1.7 times more feasible to have at least one physical limitation as those with the highest vitamin D levels. Among participants those aged 55 to 65, and those having the lowest vitamin D levels were twice as probable to have at least one physical limitation as those with the highest vitamin D levels.
In the older age group, 70 percent of those having the lowest vitamin D levels had at least one physical limitation, while most of those with moderate or high vitamin D levels had no physical limitations, according to the study.
The researchers also found that people with vitamin D deficiency were more likely to develop additional physical limitations over time. Seniors who have low levels of vitamin D are more likely to have mobility limitations and to see their physical functioning decline over time. The findings indicate low vitamin D levels in older individuals may contribute to the declining ability to live independently
