Psychotic symptoms are common among older adults and are seen in a wide range of conditions. Most studies examining the prevalence and correlates of psychotic symptoms among older adults have been conducted in Western populations. To address this gap the current study was undertaken to establish the prevalence and correlates of psychotic symptoms and paranoid ideation within a community sample of older adults without dementia in an Asian population.
The Well-being of the Singapore Elderly (WiSE) study was a comprehensive single phase, cross-sectional survey. All respondents were assessed using the Geriatric Mental State examination (GMS). Specific questions of the GMS were then used to establish the prevalence of hallucinations and persecutory delusions.
A total of 2,565 respondents completed the study giving a response rate of 65.6%. The prevalence of any psychotic symptoms in this population of older adults was 5.2%. The odds of hallucinations and any psychotic symptoms were significantly higher among those of Malay ethnicity, and those who had no formal education. Older adults aged 75-84 years were significantly associated with lower odds of having hallucinations (vs. older adult aged 60-74 years), while homemaker status was significantly associated with lower odds of having any psychotic symptoms.
The prevalence of psychotic symptoms among older Asian adults without dementia was higher than that reported from Western countries. Psychotic symptoms were associated with Malay ethnicity, poor cognitive performance and fewer years of schooling, visual and hearing impairment as well as depression and irritability.
精神病性症状在老年人中很常见，且在多种情况下都可出现。大多数关于老年人精神病性症状患病率及其相关因素的研究都是在西方人群中进行的。为填补这一空白，本研究旨在确定亚洲人群中无痴呆的老年人社区样本中精神病性症状和偏执观念的患病率及其相关因素。
新加坡老年人福祉（WiSE）研究是一项全面的单阶段横断面调查。所有受访者均使用老年精神状态检查（GMS）进行评估。然后使用GMS的特定问题来确定幻觉和被害妄想的患病率。
共有2565名受访者完成了研究，回应率为65.6%。该老年人群中任何精神病性症状的患病率为5.2%。马来族裔以及未接受过正规教育的人群出现幻觉和任何精神病性症状的几率显著更高。75 - 84岁的老年人出现幻觉的几率显著低于60 - 74岁的老年人，而家庭主妇身份与出现任何精神病性症状的几率显著降低相关。
亚洲无痴呆老年人中精神病性症状的患病率高于西方国家报告的患病率。精神病性症状与马来族裔、认知功能差、受教育年限少、视力和听力障碍以及抑郁和易怒有关。
