“…In the present study, the average serum 25OH-D concentrations at baseline were only 9.7 ng/ mL in both groups. It is similar to the previous data that Japanese physically disabled elderly living in nursing homes had low serum 25OH-D levels (12.0Ϯ5.2 ng/ mL) (11). Average dietary intake of vitamin D was around 300 IU/d, which is approximately 150% of the AI in DRI 2005 in both groups in the present study.…”

SummaryTo study the adequate intake (AI) for vitamin D in the elderly, we have performed an intervention study with 800 IU/d of vitamin D 3 in the institutionalized elderly. Sixty-two institutionalized elderly were randomly assigned to two groups; receiving either supplements of 200 mg calcium plus 800 IU vitamin .3 ng/mL in the Ca ϩ VD group and to 11.1 ng/mL in the Ca group. Post intervention serum 25OH-D level was significantly higher in the Ca ϩ VD group than in the Ca group ( p Ͻ 0.001). In 53 subjects (85.5%) who took more than 80% of their supplements for 30 d, serum PTH level in the Ca ϩ VD group was significantly lower than in the Ca groups ( p ϭ 0.05). Bone turnover markers were not significantly changed after intervention in either group. Daily supplementation of 800 IU vitamin D 3 was considered effective in the institutionalized elderly with minimal chance of sun exposure, but further studies with longer duration are necessary.

“…Since elderly people are much more prone to fracture, it is possible that the AI for vitamin D in the elderly in Japan would be higher. Institutionalized elderly have been our special concern, since they are at even higher risk of fracture ( 7 -9 ) and have been reported to have a high prevalence of vitamin D deficiency or insufficiency (10)(11)(12)(13)(14).…”

“…The latter was related both to resident status and vitamin D levels. As observed previously (18,21,24), SHPT is by itself an independent risk factor for hospitalization and/or death in the elderly. The prevalence of SHPT expressed as an elevated PTH and higher alkaline phosphatase was higher among the nursing home residents in our cohort.…”

Objective: To compare the prevalence of vitamin D deficiency and fracture history in nursing home residents and community-dwelling elderly subjects and to explore the association of vitamin D levels with various characteristics. Materials and methods: Sixty-six nursing home residents and 139 community-dwelling elderly subjects participated. Marital status, medical history, medication including vitamin D supplements, smoking, past fractures were assessed. Weight and height were measured and body mass index calculated. Serum 25-hydroxyvitamin D (25-OHD), PTH, Ca, phosphate, creatinine and eGFR were determined. Results: In the nursing home residents 25-OHD was lower

“…We defined inactive elderly people as those who spent most of the day in their bedroom (Nashimoto et al 2002). The subjects had prolonged decreases in muscle contractile activity, such as those associated with a sedentary lifestyle, periods of prolonged bed rest, and inactivity as a consequence of congestive heart failure, stroke, chronic obstructive pulmonary disease, limb casting, and muscle unloading (i.e., microgravity).…”

Abdominal muscle strength declines easily with the process of aging and/or disuse, and it is difficult to strengthen weak abdominal muscles in the inactive elderly. In the present study, we applied surface electrical stimulation (ES) to the abdomen of inactive elderly people to investigate its chronic effects. Twenty inactive elderly people (65-89 years) who spent most of the day in their bedroom participated in the study. The subjects were assigned to ES and non-ES groups in a random order. In addition to conventional physical therapy and occupational therapy, ES was applied to both sides of the flank of 10 subjects (ES group) for 8 weeks. For evaluation of the abdominal muscles, the cross-sectional area (CSA) was measured with computed tomography and the electrical muscle activity (iEMG) was measured by electromyography. Functional examinations were performed at 2, 4, and 8 weeks after the beginning of the study with the following parameters: grip strength; maximum walking speed (WS); movement time for sitting up (MSU); number of trunk flexions (NTF); flexibility of the trunk; sit-to-stand time (STS); and Barthel index (BI) score. In the ES group, the NTF and MSU were significantly improved at 4 weeks and thereafter. Furthermore, the STS and WS were also improved significantly after 8 weeks (p < 0.05). The CSA and iEMG both increased significantly (p < 0.05). However, the flexibility of the trunk and BI score did not change. In conclusion, ES to the abdomen has the potential to improve motor function in the inactive elderly.

Hypovitaminosis D and hyperparathyroidism in physically inactive elderly Japanese living in nursing homes: Relationship with age, sunlight exposure and activities of daily living

Abstract: Hypovitaminosis D and hyperparathyroidism are commonly seen in elderly Japanese with low ADL levels. Hypovitaminosis D seems to adversely affect PTH levels, especially in the very elderly.
