The purpose of the study was to determine whether psychosocial stress during different life periods could be a risk factor in the etiology/pathogenesis of insulin-dependent diabetes mellitus (IDDM) in children.
In a population-based sample of 67 case patients 0–14 years of age and 61 matched healthy control subjects, life events during the entire lifespan before the onset of IDDM were recorded as well as measures of child behavior before onset, social support, and family function.
Negative life events occurring during the first 2 years of life, life events with difficult adaptation, child behavioral deviances, and a more chaotic family function were more common in the case group. A stepwise logistic regression indicated that negative life events in the first 2 years increased the risk of IDDM and that premorbid child behavior as well as dysfunctional hierarchical family pattern affect the risk.
Stress early in life may increase the risk for IDDM, presumably by affecting the autoimmune process. To confirm these results, it is necessary to make a truly prospective study.
