The international prevalence of psychotic symptoms in older subjects without dementia varies from 0.9% to 8.0%. However, an analysis of these symptoms in developing countries has not been undertaken.
To determine the prevalence and to correlate these symptoms with socioeconomic and clinical characteristics.
A community-based sample aged 60 years and older was evaluated. Those who screened positive for dementia, cognitive and functional impairment or significant depressive symptoms were excluded, resulting in 1125 individuals.
The prevalence of psychotic symptoms was 9.1% (visual/tactile hallucinations, 7.8%; auditive hallucinations, 7.5%; persecutory delusions, 2.9%). Subjects with psychotic symptoms had lower Mini Mental State Examination and The Bayer Activities of Daily Living Scale scores, fewer years of schooling, belonged to lower socioeconomic classes compared with non-psychotic subjects, and 80% had clinical comorbidities.
The prevalence was in the upper range of international data. Significant relationships were found between psychotic symptoms and lower Mini Mental State Examination score, fewer years of schooling and lower socioeconomic class. Clinical comorbidity was also very frequent.
在无痴呆的老年受试者中，国际上精神病性症状的患病率在0.9%至8.0%之间。然而，尚未对发展中国家的这些症状进行分析。
确定患病率，并将这些症状与社会经济和临床特征相关联。
对一个年龄在60岁及以上的社区样本进行评估。排除那些痴呆、认知和功能障碍或显著抑郁症状筛查呈阳性的个体，最终纳入1125人。
精神病性症状的患病率为9.1%（视幻觉/触幻觉，7.8%；听幻觉，7.5%；被害妄想，2.9%）。与无精神病性症状的受试者相比，有精神病性症状的受试者简易精神状态检查表和拜耳日常生活活动量表得分较低，受教育年限较少，属于社会经济阶层较低者，且80%有临床合并症。
患病率处于国际数据的较高范围。发现精神病性症状与较低的简易精神状态检查表得分、较少的受教育年限和较低的社会经济阶层之间存在显著关系。临床合并症也非常常见。
