Risk faktors for fracture in middle-aged men and women

Sammanfattning: The number of fractures is increasing worldwide, and fractures frequently cause long-term disability, impaired quality of life and sometimes death. The Malmö Preventive Project, a population-based, prospective study, consisting of 22 444 men, mean age 44 and 10 902 women, mean age 50 years, provides data for evaluation of common public health conditions, such as fracture and diabetes. The follow-up was 19 and 15 years for men and women, respectively. Multiple risk factors for fracture were identified.

In women, the most important risk factors were advancing age (relative risk RR 1.56, Confidence Interval 95% 1.45-1.68), previous fracture (RR 2.00, CI 95% 1.56-2.58) and diabetes (RR 1.87, CI 95% 1.26-2,79). In men, advancing age (RR 1.19, CI 95% 1.12-1.26), mental health problems (RR 1.92, CI 95% 1.47-2.51), increased levels of ? glutamyl transferase (RR 1.24, CI 95% 1.18-1.31) and diabetes (RR 2.38, CI 95% 1.65-3.42) were major risk contributors.

Impaired glucose tolerance, evaluated through an oral glucose tolerance test, was in both genders associated with a substantially decreased risk of fractures, independent of age, BMI and smoking.

This thesis has identified multiple risk factors for low-energy fracture, in both men and women, highlighting diabetes and mental health problems as major contributors in this age group. Current management strategies and therapeutic guidelines are not addressing a number of the identified risk factors. Subsequently, risk assessment can be substantially improved by adding these risk factors to intervention algorithms for middle-aged individuals.
