We revue the epidemiology of cardiovascular disease in the elderly, their relationship to arterial stiffness. The measurement of arterial stiffness is of considerable increasing interest in this early 21 century. This paper is focusing on modeling, in different measurement methods. Several measurement techniques are presented. A review of the bibliography that explain the link between cardiovascular risk factors and arterial stiffness is summarized, as are the relationships between the various risk factors and arterial stiffness. The current role of these measurement methods seems to be time consuming although the European consensus recommends the measure once a year in the management of vascular patients. New techniques for the assessment of the arterial stiffness, more reproducible and easy to use, could ultimately trivialize this measurement, contributing in medical practice to the assessment and the management of the vascular risk.

Osteoporosis concerns 50% of women over 80 years. Prevalence of energizing and protein malnutrition is high as for institutional elderly people as for community dwelling elderly people. Malnutrition, physical inactivity and many etiological factors lead to tissular losses especially on protein compartment, named sarcopenia. Among the common etiological factors, some cytokines have an effect on proteolysis and bone restructuring, interfering with osteoclast metabolism. Inflammation or stress, mechanisms which product cytokines, are responsible for unfavourable bone restructuring and for a loss of protein mass, deteriorating the muscular functional prognostic. We researched articles on Medline® between 1980 and 2010 about relations between protein compartment, malnutrition and bone density. Several studies in literature suggest that increase in protein intake in daily caloric needs could have a positive effect on bone mineral density and functional performances (in primary prevention as in secondary prevention). So, primary and secondary preventive measures must comprise an increase in protein intake and a sufficient physical activity.
