Brief summary
With the rapid aging and worsening psychological problems worldwide, the special focus on somatic symptom and other psychological diseases of the older population is needed. However, there is no research comparing the incidence of somatic symptom between elderly and non-elderly, and clinical relevance with somatic symptom is uncertain. The study aims to clarify the prevalence of somatic symptom, depression and anxiety disorders in China, to compare physical and psychological difference between the elderly and non-elderly and to explore risk factors for somatic symptom in the elderly.
Detailed description
With the steadily increasing of life expectancy, the aging people is expected to 2 billion by 2050, which brings the deeper demand on the quality of life improvement. The psychological problems is an important factor affecting the quality of life. As reported, 73.6% of urban residents were with mental sub-health, indicating that psychological problem has grown into inevitable issues in hindering healthy development. The elderly, compared with the non-elderly, have unique social and biological characteristics, so psychological problem of the older population deserves special focus. Literatures have investigated aged people with depression or anxiety disorder, but somatic symptom in elderly have rarely been addressed. Somatic symptom disorder prevalence in elderly in European ranged from 0-13.5%. However, there is no research comparing the incidence of somatic symptom, anxiety and depression between elderly and non-elderly and revealing the prevalence of somatic symptom under Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. Investigators use Somatic Symptom Scale-China (SSS-CN) questionnaire to assess the presence and severity of the symptoms. Patient Heath Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder Screener (GAD-7) are used to evaluate depression and anxiety disorder respectively. The study aims to clarify the prevalence of somatic symptom, depression and anxiety disorders in China, to compare physical and psychological difference between the elderly and non-elderly and to explore risk factors for somatic symptom in the elderly.
Interventions
