Abstract: The purpose of this study was to examine the possible inverse relationship between total meat intake or processed meat intake on insulin sensitivity as mediated by body mass index (BMI). The Quantitative Insulin Sensitivity Check Index (QUICKI) was used to calculate participants’ insulin sensitivity. Cross-sectional data were used from Visit 1 of the Atherosclerosis Risk In Communities cohort. Mediation analysis was conducted using the PROCESS macro for SPSS. The mean BMI was 27.3 kg/m2, total meat intake was 1.76 servings per day, processed meat intake was 0.44 servings per day, and the mean QUICKI score was 0.34. As hypothesized, total meat intake was significantly associated with lower insulin sensitivity. The significant inverse total association model was -0.0044 (95% CI: -0.0054, -0.0034) with a significant inverse BMIassociation [-0.0029 (95% CI: -0.0033, -0.0024)] which indirectly accounted for 66% of the association between total meat intake and QUICKI. The processed meat intake association was partially mediated by BMI. Ultimately, these findings suggest that the majority of the association of meat intake with insulin sensitivity is contributed by its association with BMI.
