The association between food group-based inflammatory score and cardiometabolic disorders in Ganzhou City of China

This cross-sectional study systematically evaluated the association between the Food Group-Based Inflammatory Score (FGBIS) and cardiometabolic disorders among adults in Ganzhou City, China. The results demonstrated a significant correlation between FGBIS levels and metabolic abnormalities, with differential distribution patterns observed across sex (P = 0.044) and marital status (P = 0.008) groups. Regression analyses revealed a significant positive association between age and FGBIS, while hypertension status showed an inverse relationship with FGBIS. Gender-stratified analyses further indicated that higher FGBIS levels in males were significantly associated with greater age (β = 0.027), and smoking initiation among non-smoking males substantially associated with higher FGBIS (β = 0.500). In contrast, female hypertensive patients exhibited lower FGBIS levels (β=-0.268). These findings not only reveal distinct demographic patterns in dietary inflammatory effects but also provide important implications for public health practice: targeted anti-inflammatory dietary interventions may effectively mitigate the development of metabolic disorders, and incorporating FGBIS assessment into chronic disease prevention systems could facilitate the development of personalized dietary guidelines, thereby offering scientific evidence for improving population cardiometabolic health.
