title = "Risk of falling in older women",
abstract = "We propose a weighted average approach to measure the risk of falling in older women. We consider four causal variables of falling, namely serum 25-OHD levels, medication use, fracture, and age. We use five methods to derive linear equations with these four factors as independent variables in the linear equations with risk of falling as the dependent variable.",

note = "Funding Information: Participants: The participants have been described in detail in a previous article, Ref. 11. Brie°y, participants were recruited as a population-based sample from a 9-county, largely rural area in eastern Nebraska (latitude 41.4°N), with the use of random telephone dialing of all listed telephones in the counties concerned. Inclusion criteria consisted mainly of age > 55 years, absence of known cancers, and both mental and physical status su±ciently good to permit four-year participation. 1180 women meeting inclusion criteria were enrolled. One woman was excluded because of a history of hypoparathyroidism and being treated with 50,000 IU vitamin D daily for the past 25 years. Mean (± SD) age at enrollment was 66.7 ± 7.3 years, body mass index (BMI in kg/m2) was 20.0 ± 5.7, and baseline serum 25 (OH)D was 71.8 ± 20.3 nmol/L. Although there were no ethnic inclusion criteria, all participants were white in ancestry. The project had been approved by Creighton University's Institutional Review Board, and all participants gave written consent. Study visits were conducted at a research site established in a community hospital in the rural area. The study was funded by DHHS AG14683-01A2.
