PG - 556 LID - 10.3389/fendo.2018.00556 [doi] LID - 556 AB - Objective: Long-term positive energy balance promotes the development of obesity, a main risk factor for type 2 diabetes mellitus (T2DM). While an association between increased resting metabolic rate (RMR) and insulin sensitivity (IS) was shown previously, the underlying mechanisms remain unclear. Aim of the mediator analysis was to investigate the role of inflammation within the association between RMR and IS. Methods: Anthropometric, clinical, and lifestyle data were collected according to standard operating procedures. RMR was measured using indirect calorimetry. Homeostasis model assessment for insulin resistance (HOMA-IR) was used as an IS parameter and C-reactive protein (CRP) was measured to represent the inflammatory status. Statistical analyses were performed using SPSS. Results: The analysis included 782 adults (517 females) with a mean age of 32.4 +/- 12.0 years and a mean body mass index (BMI) of 24.6 +/- 5.2 kg/m(2). Regression analysis indicated a significant evidence for associations between RMR and HOMA-IR (ss = 39.3 +/- 7.3 kcal/d; p
