Objectives: The goal of this session is to examine current diagnostic incidence and medical and psychiatric comorbidities of adjustment disorder and stress-related disorders using data obtained from Korea's National Health Insurance (NHI) database between 2010 and 2012. Methods: We used data from the NHI that covered the period from January, 2010 to December, 2012. We selected our subjects according to age-groups (ages 0-6, 7-12, and 13-18 years), all of whom had at least one medical claim containing an ICD-10 code for the diagnosis of an adjustment (F432) or stress-related disorder (F430, F431, F438, F439) during the study period. We compared incidence in accordance with age and gender, and we analyzed comorbidity through the ICD-10 code data. Results: In Korea from 2010 to 2012, the overall diagnostic incidence of adjustment disorder was 0.08 percent, and the overall diagnostic incidence of stress-related disorders was 0.065 percent. The total number of incident cases of adjustment disorder were as follows: 1,890 (ages 0-6 years); 5,742 (ages 7-12 years); and 19,259 (ages 13-18 years). In addition, the total number of incident cases of stress-related disorders were 2,330 (ages 0-6 years); 4,577 (ages 7-12 years); and 14,005 (ages 13-18 years). There were more boys between the ages of 0 and 12 years, and there were more girls between the ages of 13 and 18 years who exhibited both adjustment and stress-related disorders. The psychiatric comorbidity ratios of adjustment and stress-related disorders were 47.9 and 40.9 percent, respectively. The most common psychiatric comorbidity was affective disorder (F30-F39) for adjustment disorder and stress-related disorders, whereas the next most common comorbidity was anxiety disorder (F40-F42). When the patients were hospitalized, the most common medical comorbidities for adjustment and stress-related disorders were gastrointestinal (K00-K99) and respiratory disorders (J00-J99). Conclusions: This is the first epidemiology report of adjustment and stressrelated disorders in Korea using data from the NHI. Our findings indicate that both disorders were most diagnosed during adolescence and that we should pay attention to the comorbidities. Further investigation is needed to examine the psychosocial variables related to the development and precipitating factors of adjustment and stress-related disorders.
