Epidemiology of low back pain: what's new?

Les indicateurs de frequence de la lombalgie ont ete relativement stables dans la derniere decennie, comme en attestent les resultats d'enquetes realisees sur ce sujet en France et ailleurs dans les pays industrialises. Ce constat d'echec relatif de la prevention primaire a donne lieu a une intensification des efforts de recherche dans le domaine des facteurs contributifs de la lombalgie chronique. Ces facteurs sont assez bien documentes maintenant et les resultats des etudes convergent entre les pays. Malgre tout, la frequence populationnelle de la lombalgie chronique a peu evoluee. La recherche s'oriente presentement vers le transfert des donnees de recherche pour la pratique clinique, avec une insistance sur des moyens pratiques a mettre en œuvre par le clinicien, par les patients et par les praticiens de la sante au travail, et sur la coordination des actions entre ces acteurs. Au plan de la recherche, emergent, pour la premiere fois, des consensus internationaux pour definir la lombalgie, sa gravite, son evolution et ses facteurs de risque, incluant les contraintes ergonomiques en milieu de travail. Ces travaux devraient faciliter les echanges d'information entre les pays pour une meilleure interpretation et utilisation des connaissances par les milieux cliniques et de travail.
