Conceptual Framework for the Metabolic Syndrome

Environmental causes are responsible for the epidemic of the metabolic syndrome (NCEP)

Personal Dx of HTN, TGL, low HDL or CVD
Acanthosis nigricans



Polycystic ovarian syndrome (PCOS)
Nonalcoholic fatty liver disease (NAFLD) Cancer (obesity related)
n = 2,815 (age 25-64) – Both NCEP and WHO metabolic syndrome, 509 – NCEP alone, n=197 – WHO alone, n=199 12.7 year follow-up (229 deaths) Three populations considered – Overall population – No CVD at baseline – No CVD or diabetes at baseline (primary prevention)
–
Treatment:
reduce obesity and increase activity

Insulin resistance is the underlying cause of the metabolic syndrome (WHO)
–
Treatment:
a) reduce obesity and increase activity b) insulin sensitizers
