Abstract

Summary

Objectives

The present study was designed to determine the most applicable FRAX^® model for the Iranian population. Methods: Seventy four men and women (with the mean age of 70 years), who had experienced at least a fragility fracture in their life, along with 162 individuals with no such an experience (with the mean age of 66 years), were enrolled in this study. Fracture probabilities were calculated using FRAX^® models from Jordan, Lebanon and the US.

Results

We found a significant difference in the probability rate between the fracture cases and the controls; the rate, however, was lower than the recommended threshold for intervention, especially for the Lebanese and the Jordanian models.

Conclusion

As for women all the three models had a good discrimination value, while the Lebanese and the Jordanian model needed to be revised. As for men, on the other hand, the Jordanian model had a low discriminative value. The Lebanese model, despite its acceptable discrimination value, needed a revision regarding its threshold. The US model was the most compatible.

Zusammenfassung

Studienziele

Diese Studie wurde konzipiert, um zu bestimmen, welches FRAX^®-Modell für die iranische Bevölkerung am besten geeignet ist.

Methoden

In diese Studie wurden 74 Männer und Frauen (Durchschnittsalter: 70 Jahre) eingeschlossen, die in ihrem Leben mindestens eine Fragilitätsfraktur erlitten haben, sowie 162 Personen ohne derartige Frakturen (Durchschnittsalter: 66 Jahre). Die Frakturwahrscheinlichkeiten wurden anhand der FRAX^®-Modelle von Jordanien, dem Libanon und der USA berechnet.

Ergebnisse

Wir haben signifikant unterschiedliche Wahrscheinlichkeiten bei den Frakturfällen und Kontrollen festgestellt. Die Rate war jedoch insbesondere bei den libanesischen und jordanischen Modellen niedriger als die empfohlene Interventionsschwelle.

Schlussfolgerung

Für Frauen hatten alle drei Modelle einen guten Diskriminationswert, allerdings mussten das libanesische und jordanische Modell überarbeitet werden. Für Männer hatte das jordanische Modell jedoch einen niedrigen Diskriminationswert. Beim libanesischen Modell musste trotz des akzeptablen Diskriminationswerts die Schwelle überarbeitet werden. Das US-Modell war am besten geeignet.
