Objectives. To estimate the dynamics of hospital admissions for affective disorders in various socio-demographic fractions.
Methods. Differences were analyzed between the years 1997 and 2001 in the total number of admissions, and in the number of first admissions by the diagnostic categories of affective disorders. Three independent variables were taken into account: age, sex, and place of residence (urban v. rural area). Comparisons were made using two rates: the number of patients per 100.000 of either general population, or population with characteristics under study.
Results. In the years 1997-2001 the frequency of hospital admissions has increased by 39%, with a similar rate for the first admissions. The most frequent causes of hospitalization were recurrent depressive disorders and depressive episodes. The highest hospitalization rates were noted in the 45-45 age range. Women were hospitalized twice as often as men. While inhabitants of urban areas were more frequently hospitalized than those living in rural areas, the difference disappeared in the 45-54 age group. During the 5-year period under study the highest increment in the number of hospital admissions was found in the group aged 45-54, being higher among women as compared to men, and among urban area dwellers as compared to inhabitants of rural areas.
Conclusions. The largest increment in the number of hospital admissions was noted in the categories of depressive episodes and recurrent depressive disorders, especially severe.
