Association Between Food Allergy, Psychological Stress, and Allostatic Load.

Allostatic load (AL), the cumulative biological burden of persistently high stress exposure, influences adult health and well-being across the lifespan, and can be measured with clinical indicators, such as BMI, blood pressure (BP), and waist-hip ratio. Adverse childhood events and other stressors contribute to AL, but stress from other sources, such as previously diagnosed chronic health conditions, has been overlooked. We hypothesized that adults with these conditions would have more stress exposures, higher perceived stress, worse mental health, and higher AL, compared to controls. A secondary analysis of deidentified data from cases with self-reported food allergies and controls found that individuals with chronic health conditions reported more stress exposures, higher levels of perceived stress, and had higher AL, compared to controls. However, other results did not support the study hypotheses. Future studies should examine additional AL measures, such as biomarkers of stress response, in individuals with existing chronic health conditions.
