Trends in calcium and vitamin D usage among older people in nursing care facilities in Australia: still falling short of the guidelines

Abstract

Objective: To determine the impact of awareness‐raising strategies of calcium and vitamin D supplements in the active management of bone health of older people living in nursing care facilities in Australia. Design: We compared data drawn from two prospective cohort studies that have evaluated falls and fractures in older people living in hostels (intermediate care facilities): the FREE study (conducted from 1996–2002, n = 1107) and the ongoing FREEDOM study (commenced in 2006, n = 1284 screened individuals). Both studies recruited older people living in a large number of nursing care facilities in northern Sydney (Australia). Results: We found a small but significant increase in both calcium and vitamin D supplementation in the FREEDOM study participants compared to those in the FREE study. Calcium alone increased from 6.2% to 10.5% (P = 0.0002), vitamin D alone from 5.8% to 7.9% (P = 0.04) and the combined use of calcium and vitamin D increased from 1.6% to 11.9% (P < 0.0001). Conclusion: There appears to be increasing awareness of the need for calcium and vitamin D supplementation in older people in nursing care facilities. However, given the high prevalence of osteoporosis and vitamin D deficiency among this population, the levels of supplementation achieved must still be considered suboptimal for treatment and prevention of osteoporosis and falls.

Associations Between Drug Burden Index and Falls in Older People in Residential Aged Care

“…A limitation of this study is that the inclusion criteria may mean that the sample population is not truly representative of the RACF population 28 . In particular, only ambulatory residents were investigated, excluding residents who could not walk.…”

Physical Functioning Measures and Risk of Falling in Older People Living in Residential Aged Care Facilities

“…The exclusion criteria limit this being a true representation of the population in RACFs [Sanchez Riera et al 2008]. This study focused on ambulatory fallers, and therefore did not include wheelchair-bound or immobile residents of the RACFs.…”
