Association between high molecular weight adiponectin levels and metabolic parameters

Area of Science:

• Endocrinology
• Cardiovascular Health
• Metabolic Syndrome

Background:

• Low plasma adiponectin is linked to obesity and insulin resistance.
• High molecular weight (HMW) adiponectin may offer greater vascular protection than total adiponectin.
• Clinical data on HMW adiponectin is limited.

Purpose of the Study:

• Investigate HMW adiponectin levels in Japanese rural residents.
• Elucidate the clinical significance of HMW adiponectin.

Main Methods:

• Measured plasma HMW adiponectin in 1,183 subjects (643 men) from a health check program.
• Utilized multivariate linear regression analysis.

Main Results:

• Median plasma HMW adiponectin was significantly lower in men (1.6-4.0 microg/mL) than women (3.7-8.6 microg/mL).
• Body weight, B-type natriuretic peptide (BNP), and HDL cholesterol were independently associated with HMW adiponectin in both genders.
• Triglyceride and serum creatinine levels were associated with HMW adiponectin in men only.

Conclusions:

• HMW adiponectin levels are lower in men than women.
• HMW adiponectin is independently associated with BNP.
• Further prospective studies are needed to confirm HMW adiponectin's utility as a cardiovascular disease biomarker.
