The influence of age and body mass index on the metabolic syndrome and its components

For each component of the metabolic syndrome and associated factors, there is a complex interaction between ageing and obesity. Some components are associated with obesity but not ageing (e.g. CRP), while others are associated with both obesity and ageing (e.g. glucose). Even when the association exists, the specific relationship can appear to be more (e.g. SBP) or less (e.g. triglycerides) linear.
