Relationship between the FRAX score and falls in community-dwelling middle-aged and elderly people.

OBJECTIVES

Falls is a risk factor for fracture. The FRAX predicts fractures. Whether the FRAX is associated with fall in both gender is inconclusive. The aim of our study is to evaluate the association between FRAX scores and falls.

METHODS

The cross-sectional study set from 2009 to 2010 included 1200 community-dwelling people who were systematically sampled in central Taiwan. The 1200 participants (men: 524; women: 676; ≥40 years old) completed questionnaires about socioeconomic status; lifestyle; medical and fall history were completed. FRAX scores with and without bone mineral density (BMD) were calculated by using the Taiwan calculator.

RESULTS

A total of 19.8% participants fell down. Binary regression models showed that diabetes mellitus history (OR: 1.61; 95% CI: 1.03-2.52), the FRAX without BMD in a continuous major score (OR: 1.06; 95% CI: 1.03-1.09), continuous hip score (OR: 1.11; 95% CI: 1.05-1.16), categorical major score ≥ 10% (OR: 1.81; 95% CI: 1.25-2.61), and categorical hip score ≥ 3% (OR: 1.80; 95% CI: 1.30-2.50) were independent risk factors for falls. FRAX with BMD in a continuous major score (OR: 1.04; 95% CI: 1.02-1.06), continuous hip score (OR: 1.06; 95% CI: 1.02-1.09), categorical major score ≥ 10% (OR: 1.52; 95% CI: 1.09-2.12), and categorical hip score ≥ 3% (OR: 1.53; 95% CI: 1.13-2.09) were also independent risk factors.

CONCLUSIONS

We concluded that FRAX scores with and without BMD were unanimously correlated with falls in community-dwelling middle-aged and elderly males and females.
