Objective To analyze the correlation between visceral fat area (VFA) and metabolic indicators such as body mass index (BMI), waist circumference, hip circumference, and glucose-lipid acid in different age groups of patients with type 2 diabetes, by organizing the database of the National Standardized Metabolic Disease Management Center (MMC) at a tertiary hospital in Shenzhen.Methods We conducted a cross-sectional study based on the MMC center, performing statistical analysis on the relevant data of 2 175 enrolled diabetes patients, categorized into four age groups: A ( <40 years), B ( 40≤ age <50 years), C( 50≤ age <65 years), D( ≥65 years).Analyze the differences in VFA, SFA, BMI, WC, HC, FBG, HbA1c, TG, TC, LDL-C, HDL-C, and UA levels among different age groups. The Pearson method was used to analyze the correlation between VFA and SFA, BMI, WC, HC, FBG, HbA1c, TG, TC, LDL-C, HDL-C, UA, and other indicators in different age groups.Results This study included 2 175 participants, comprising 1 327 males (61.3%) and 848 females (38.7%), with an average age of (53.20 ± 10.62)years. Group A has 262 participants, Group B has 425 participants, Group C has 1 178 participants, and Group D has 310 participants.In the male group, BMI, WC, HC, VFA, FBG, HbA1c, and TG were higher than those in the female group, while age, TC, LDL-C, and AST were lower than in the female group, with statistically significant differences (P < 0.05). Among patients in different age groups, younger age was associated with higher levels of BMI, WC, HC, VFA, SFA, UA, HbA1c, ALT, and LDL-C, with statistically significant differences (P < 0.05).Correlation analysis showed that VFA levels were positively correlated with BMI (r =0.436, P = 0.000), WC (r = 0.728, P = 0.000), HC (r = 0.588, P = 0.000), SFA (r = 0.686, P =0.000), UA (r = 0.289, P = 0.000), FBG (r = 0.189, P =0.000), and TG r = 0.143, P =0.000), and negatively correlated with HDL (r = -0.165, P = 0.000). In the age subgroup analysis, in Group A, VFA was positively correlated with BMI (r = 0.296, P = 0.000), WC (r = 0.799, P = 0.000), HC (r = 0.706, P =0.000), SFA (r = 0.708, P =0.000), UA (r = 0.260, P = 0.000), and FBG (r = 0.184, P = 0.003), and negatively correlated with HbA1c (r = -0.147, P= 0.018), TC (r = -0.003, P = 0.042, LDL-C (r = -0.005, P = 0.023), and HDL-C (r = -0.123, P =0.048); in Group B, VFA was positively correlated with BMI (r = 0.756, P = 0.000), WC (r = 0.767, P = 0.000), HC (r = 0.664, P = 0.000), SFA (r = 0.750, P = 0.000), UA (r = 0.307, P = 0.000), FBG (r =0.226, P =0.000), and TG (r =0.143, P = 0.003), and negatively correlated with HDL-C (r = -0.161, P = 0.000); in Group C, VFA was positively correlated with BMI (r = 0.693, P = 0.000), WC (r = 0.696, P = 0.000), HC (r = 0.537, P = 0.000), SFA (r = 0.663, P = 0.000), UA (r = 0.256, P = 0.000), FBG (r = 0.179, P = 0.000), and TG (r = 0.140, P = 0.000), and negatively correlated with HDL-C (r = -0.161, P = 0.000); in Group D, VFA was positively correlated with BMI (r = 0.603, P = 0.000), WC (r = 0.633, P = 0.000), HC (r = 0.411, P = 0.000), SFA (r = 0.602, P = 0.000), UA (r = 0.304, P = 0.000), and FBG (r = 0.166, P = 0.003), and negatively correlated with HDL-C (r = -0.152, P = 0.007). The overall research results indicated that in the diabetic population, BMI, WC, HC, SFA, UA, FBG, and TG were positively correlated with VFA, while HDL-L was negatively correlated. However, HbA1c, TC, and LDL-C did not show significant correlations with VFA. Further age-stratified analysis revealed that as age increased, the correlation between BMI and VFA became increasingly significant, while the correlations between WC and HC weakened.Conclusion The type 2 diabetes mainly occurs in the middle-aged and elderly population. BMI, WC, HC, SFA, TG, and UA are the primary risk factors affecting VFA. In the young and middle-aged group, BMI, TG, and UA have a significant impact on diabetes patients, necessitating strengthened management efforts for this demographic.
