Association between coffee and adiponectin according to the obesity status: A cross-sectional analysis of the Japan Multi-Institutional Collaborative Cohort Study in Tokushima, Japan
M Ishizu et al, 2025. Association between coffee and adiponectin according to the obesity status: A cross-sectional analysis of the Japan Multi-Institutional Collaborative Cohort Study in Tokushima, Japan, Nutrition, Metabolism and Cardiovascular Disease.
ABSTRACT:
Background and Aims: Coffee may contribute to the prevention of metabolic abnormalities in both obese and normal weight Japanese adults. Although evidence suggests a relationship between coffee and serum adiponectin, stratified analyses according to the obesity status have not yet been reported. This cross-sectional study examined the relationship between coffee intake and serum high molecular weight (HMW)-adiponectin, which is the most active form of adiponectin, according to the obesity status.
Methods and Results: The baseline data of 606 participants (aged 35-69 years) living in Tokushima prefecture in the Japan Multi-Institutional Collaborative Cohort Study were analyzed. Coffee intake was assessed using a questionnaire. Participants were stratified by the presence or absence of obesity (normal weight: BMI<25 kg/m2; obesity: BMI≥25 kg/m2). Multiple linear regression analyses adjusted for potential confounders were performed to examine the association between coffee intake and HMW-adiponectin or other diabetic factors. Coffee intake was associated with serum HMW-adiponectin in normal weight subjects (Coffee intake ≥3 cups/day, β for model 2 1.02, 95% CI 0.30, 1.74), but not in obese subjects. Moreover, filtered/instant coffee intake was associated with serum HMW-adiponectin in normal weight subjects (Coffee intake ≥3 cups/day, β for model 2 0.93, 95% CI 0.21, 1.65), but not in obese subjects.
Conclusion: The present study suggests that coffee intake, particularly filtered/instant coffee, is associated with serum HMW-adiponectin in normal weight Japanese adults.
