    METABOLIC SYNDROME Metabolic Syndrome Discuss the metabolic syndrome, including its definition, core components, associated abnormalities, genetic and environmental influences, and approaches for identifying its genetic determinants. Additionally, analyze the prevalence and correlates of metabolic syndrome in different populations, using relevant studies to support your discussion. Your answer should be comprehensive and supported by current research findings. (Word count: 1500 - 2000 words)

    METABOLIC SYNDROME A syndrome is defined as "The aggregate of signs and symptoms associated with any morbid process, and constituting together the picture of the disease". The metabolic syndrome represents a heterogeneous group of metabolic disorders, the central component being insulin resistance. It can involve multiple metabolic pathways that results in dyslipidaemia , abdominal obesity, microalbuminuria and hypertension. The WHO has defined the metabolic syndrome as impaired insulin sensitivity, glucose intolerance or diabetes mellitus in combination with at least two other metabolic derangements, including abdominal obesity, dyslipidaemia (HDL - cholesterol levels and/or elevated plasma triacylglycerol (TAG) concentrations) and urinary microalbuminuria. The National Cholesterol ducation Program Adult Treatment Panel III (Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults, 2001) have proposed that individuals with the metabolic syndrome have three or more of the following metabolic derangements, including central obesity (waist girth >1020mm in men or >880mm in women), low HDL - cholesterol concentrations (<1.1 mmol/l for men or <1.3 mmol/l for women), hypertriacylglycerolaemia (>1.7 mmol/l), hypertension (blood pressure >130/85mmHg) or fasting hyperglycaemia (>6.1 mmol/l). Thus, the metabolic syndrome represents a genetically - heterogeneous group of metabolic disorders sharing insulin resistance. Abnormalities associa ted with the metabolic syndrome which are as follows : - The core cluster
