Official Title

Study to Establish Reference Curves for Bone Mineral Density (BMD) and Body Composition (BC) in Women Aged 20-89 MONIKA

Brief Summary

Up-to-date normalcy curves for bone mineral density and body composition (fat and lean mass), are currently lacking. DMS IMAGING is therefore financing the MONIKA study, with Nîmes University Hospital as sponsor.

Some 425 healthy female volunteers aged 20 to 89 will be recruited from three centers (Nîmes, Montpellier and Lyon). A bone density scan at various bone sites (femur, rachis, radius and whole body) will provide up-to-date normalcy curves for bone mineral density as well as body composition (fat and lean mass). These measurements should help to better understand bone physiology and the links that may exist between bone tissue and muscle and adipose tissue.

This is a prospective multicenter cross-sectional descriptive study of healthy female volunteers. The study population is made up of healthy female volunteers from Europe, the Middle East and North Africa aged between 20 and 89, stratified into 7 age groups.

Detailed Description

Bone densitometry using dual-photon X-ray absorptiometry (DXA) is the standard technique for measuring bone mineral density. According to the International Osteoporosis Foundation (IOF), if a single site is to be preferred, it should be the total hip or femoral neck, using a single NHANES III reference curve. It should be stressed, however, that this curve was obtained from a North American population with anthropometric parameters, notably body mass index (BMI), that differ from those of European populations, and more particularly of European, Middle Eastern and North African origin.

So far, only one reference curve has been obtained in France, from the OFELY study in 1993.

Given the age of this cohort and the possibility of changes in BMI over time in the population of European, Middle Eastern and North African origin, but even more so, the impossibility of transposing this curve onto new DXAs of different brands, new reference curves need to be developed. DMS IMAGING is therefore financing the MONIKA study, with Nîmes University Hospital as sponsor.

As part of this study, some 425 healthy female volunteers aged between 20 and 89 will be recruited from three centers (Nîmes, Montpellier, Lyon). A DXA examination at various bone sites (femur, rachis, radius and whole body) will provide up-to-date normalcy curves for BMD, but also for body composition (fat and lean mass), which are currently lacking. Access to this population could also enable us to better understand bone physiology and the links that may exist between bone tissue and muscle and adipose tissue.
