Perceived Weight Discrimination and 10-Year Risk of Allostatic Load Among US Adults
Background Discrimination promotes multisystem physiological dysregulation termed allostatic load , which predicts morbidity and mortality . It remains unclear whether weight-related discrimination influences allostatic load . Purpose The aim of this study was to prospect ively examine 10-year associations between weight discrimination , allostatic load , and its components among adults 25–75 years in the Midlife Development in the US Biomarker Sub study . Methods Participants with information on weight discrimination were analyzed ( n=986 ) . At both timepoints , participants self-reported the frequency of perceived weight discrimination across nine scenarios as “ never/rarely ” ( scored as 0 ) , “ sometimes ” ( 1 ) , or “ often ” ( 2 ) . The two scores were averaged and then dichotomized as “ experienced ” versus “ not experienced ” discrimination . High allostatic load was defined as having ≥3 out of 7 dysregulated systems ( cardiovascular , sympathetic/parasympathetic nervous systems , hypothalamic pituitary axis , inflammatory , lipid/metabolic , and glucose metabolism ) , which collectively included 24 biomarkers . Relative risks ( RR ) were estimated from multivariate models adjusted for sociodemographic and health characteristics , other forms of discrimination , and BMI . Results Over 41 % of the sample had obesity , and 6 % reported weight discrimination at follow-up . In multivariable-adjusted analyses , individuals who experienced ( versus did not experience ) weight discrimination had twice the risk of high allostatic load ( RR , 2.07 ; 95 % CI , 1.21 ; 3.55 for baseline discrimination ; 2.16 , 95 % CI , 1.39 ; 3.36 for long-term discrimination ) . Weight discrimination was associated with lipid/metabolic dysregulation ( 1.56 ; 95 % CI 1.02 , 2.40 ) , glucose metabolism ( 1.99 ; 95 % CI 1.34 , 2.95 ) , and inflammation ( 1.76 ; 95 % CI 1.22 , 2.54 ) , but no other systems . Conclusions Perceived weight discrimination doubles the 10-year risk of high allostatic load . Eliminating weight stigma may reduce physiological dysregulation , improving obesity-related morbidity and mortality
