Abstract 179: Vascular Inflammation and Hepatic Steatosis among the Overweight Metabolically Healthy Individuals and Normal Weight with Cardiometabolic Risk Factor Clustering
BACKGROUND Emerging literature has elucidated a new phenotype, metabolically healthy overweight/obese (MHO) who have a similar CVD risk to normal weight individuals. The aim of the study was to compare the relative risk of both phenotypes with subclinical inflammatory-cardiometabolic disorders.
METHODS We evaluated 6,464 healthy non diabetic Brazilian subjects (43±10 years, 79% males). Those with <2 metabolic risk factors (MRF)were considered metabolically healthy and those with BMI≥25 kg/m2 as overweight (OW). High sensitivity C reactive protein (hs-CRP) was measured to assess degree of underlying inflammation and hepatic steatosis (HS) was determined via abdominal ultrasound.
RESULTS Overall, 52% OW individuals were metabolically normal, and 11% normal-weight had≥2 MRF. The respective prevalence for elevated CRP (≥ 3 mg/dl) was 28% vs 16%, p<0.0001) and 71% vs 28% for HS, respectively. As compared to those with normal weight/metabolically benign, the highest risk of elevated CRP & HS was noted among those with overweight/metabolically unhealthy individuals (table). Both MHO individuals & normal weight metabolically unhealthy participants had similar association with elevated CRP & HS.
CONCLUSION Our study highlights that healthy overweight/obesity & normal weight metabolically unhealthy phenotypes are not entirely benign and efforts are needed to reverse these conditions.
