The link between allergic disease and depression in young adults: A structural equation modelling analysis

Perla A Vargas*, Agnes Bucko and Elias Robles

Background: The co-occurrence of multiple interacting medical and psychological disorders is extremely common. A significant association between allergic disease (ADz - e.g., asthma, allergic rhinitis, allergic dermatitis) and depression has been reported. Objective: Path analysis models using cross-sectional data were constructed to evaluate the inter-relationships among underlying co-occurring factors known to impact depression in young adults. Method: 885 college students (21.80 ± 3.22 years old) completed an online survey assessing current ADz, sleep quality, pain/discomfort, Body Mass Index, stress, substance use, Internet addiction, physical activity, social support and depression. Results: Our findings suggest that ADz is only one of multiple factors modulating depression. Six factors had significant direct effects (all p < .05) on depression: female gender, sleep quality, pain/discomfort, stress, Internet addiction, and social support. ADz, Body Mass Index, and substance use had only indirect effects (all p < .05). Social support was associated with better sleep, less depression and less stress. Physical activity had no measurable effect on depression. Conclusions: This study is the first attempt to evaluate the complex interrelations between ADz, depression and co-occurring factors. The complex interactions between variables in the model highlight the need to study these factors conjointly. Future longitudinal studies are needed to determine the temporal order and to validate causal pathways.
