Psychiatric Morbidity Among Older Hospitalized Patients.

Background: Globally, life expectancy is increasing, leading to an equal proportion of elderly and young individuals, which carries extensive implications. In Bosnia and Herzegovina (BiH), the average age at death in 2021 was 77 years, positioning BiH in the middle of the global list of average life expectancy. Current studiesinvestigate whether the prevalence of psychiatric disorders increases or decreases with age, but results are inconsistent regarding the role of age.There is no prior research on mental disorders in the elderly population in BiH. The experience of the previous war in BiH and the post-war complex "transitional period" have been associated with specific challenges to the mental health of this population, inspiring our research topic.

Objective: The aim of this study was to investigate the psychiatric morbidity in hospitalized individuals aged≥55 years.

Methods: The sample consisted of all patients over age 55 treated at the Department of Psychiatry in Tuzla between January 2018 and December 2020 (N=637), divided into four age categories. Data were obtained from medical records, and for research purposes, a specific questionnaire was constructed.

Results: The predominant psychiatric morbidity stemmed from the category of affective disorders, most common within the "55-64 years" age group, while organic mental disorders were more prevalent in other age groups.Substance use disorders were present in patients aged "55-64 years", with a sharp decline in their prevalence in older age. Female participants had a significantly higher prevalence of affective, psychotic, neurotic, and stress-related disorders, whereas male participants exhibited an increased prevalence of organic mental and substance use disorders.

Conclusion: In total sample, the most prevalent diagnoses belong to the category of affective disorders. Female were most frequently diagnosed with affective disorders, whereas organic mental disorders and substance use disorders prevail in male.
