Stressful life events and psychiatric comorbidity in acne-a case control study

Possibility of a causal influence of emotional stress, on the course of various skin diseases, has been postulated. However, it is still inconclusive about the role of stressful life events in acne. In this background, the present study was carried out to know its role in acne.

Consecutive one hundred patients who were diagnosed with acne vulgaris in the age group of 12 to 45 years were included. Age and sex matched controls were taken. A semistructured proforma was used to collect sociodemographic details. Stressful life events were assessed using presumptive stressful life event scale. Anxiety was evaluated using Hamilton Anxiety Rating scale and Depression by Hamilton Depression Rating Scale.

There was no difference in total stressful life events in past one year between patients and controls. The undesirable life event was present in 65 patients and 50 controls, this difference was statistically significant. Getting married or appearing for exams were the most common stressful life event in patients. Forty patients had comorbid psychiatric illness whereas in controls comorbidity was in 24 and this difference was statistically significant.

The undesirable stressful life events and psychiatric comorbidity were more in acne patients than in controls.
