Early Childhood Stress and the Risk of Developing Psoriasis: A Cohort Study

Area of Science:

• Dermatology and Environmental Health
• Pediatric Psychology and Epidemiology

Background:

• Environmental factors are recognized triggers for psoriasis onset.
• The impact of early childhood stress on long-term health outcomes, including dermatological conditions, requires further investigation.

Purpose of the Study:

• To examine the association between early childhood stress and the subsequent development of psoriasis.
• To determine if a "new family structure" before age eight is a risk factor for psoriasis.

Main Methods:

• Utilized data from the All Babies in Southeast Sweden (ABIS) prospective birth cohort (n=16,145).
• Collected parental-reported stress factors via questionnaires at ages 1, 3, 5, and 8.
• Identified psoriasis cases through the Swedish National Patient Register and performed statistical analyses using R.

Main Results:

• A "new family structure" (e.g., parental divorce, new siblings/adults) before age one was associated with an increased psoriasis risk (OR=4.19) in univariate analysis.
• Integrating data up to age eight, a "new family structure" consistently showed a trend towards increased psoriasis risk (OR=3.40 univariate, OR=2.91 adjusted), though not statistically significant in the adjusted model.
• The observed effect size for "new family structure" remained substantial even when adjusted for confounders.

Conclusions:

• Experiencing a "new family structure" during the first eight years of life is linked to an elevated risk of developing psoriasis.
• Early life psychological stress from family changes may represent a significant environmental factor contributing to psoriasis development.
• Further research with larger cohorts or different methodologies may be needed to confirm the statistical significance of this association in adjusted models.
