Biochemical Predictors for Osteoporotic Fractures in Elderly Chinese – A Longitudinal Study

Abstract

In a longitudinal study of 283 elderly subjects aged 60 years or over living in the community, 9 subjects (7 women and 2 men) developed osteoporosis-related fractures in 30 months. These subjects initially had higher random urinary hydroxyproline/creatinine and calcium/creatinine ratios, and lower plasma 25-hydroxyvitamin D concentrations. These biochemical variables may be useful predictors of osteoporosis-related fractures and may provide a suitable community screening method to identify those most at risk.
