Abstract Objective: To evaluate the association between dietary fiber intake and obesity in Japanese outpatients with type 2 diabetes, as well demographic factors influencing this association. Design: Cross-sectional study nationwide registry data on diabetes (2014-2019). Diet was self-reported via a Food Frequency Questionnaire. Obesity defined BMI ≥25 kg/m . Setting: Clinics throughout Japan. Participants: 1,565 (63.1% men; age range 30–89 years). Results: Multivariate analysis revealed that higher associated lower risk of all participants (95% CI = 0.439–0.795, p < 0.001). Stratified showed significant inverse men older groups (59–89 years), but not women or younger group (30–58 In men, healthier lifestyle behaviors, including increased physical activity (p 0.001) non-smoking 0.001), stronger associations compared to women. Vegetables, fruits, soybeans/soy products were strongly correlated fiber, while grains had weak correlation. Folate micronutrient most fiber. Conclusion: Higher risk, particularly groups. These findings emphasize need for targeted public health initiatives promoting diverse fiber-rich foods effectively manage obesity. Further research is needed understand sex- age-specific fiber-obesity relationship populations.
