HDS-R在广东沿海农村老年期痴呆筛查中的应用

Application of HDS-R in Screening Senile Dementia in Coastal Rural Areas of Guangdong Province

探讨HDS R在老年期痴呆筛查中的应用及其影响因素。方法 :本研究用改良长谷川痴呆量表 (HDS R)对广东沿海三个县中 10 18名世居农村 ,年龄≥ 65岁的老年人进行痴呆筛查。结果 :HDS R分为 0— 32 5分 ,平均 2 3 50± 5 80分 ,经逐步回归分析表明年龄、教育程度、痴呆诊断、听力、性别是影响HDS R评分的重要因素 ;HDS R界限分为 17分时 ,敏感度 95 1% ,特异度为 97 7%。结论 :年龄、教育程度、痴呆诊断、听力、性别是影响HDS R评分的重要因素 ,HDS R因其特异度和敏感度高且易于实施、项目简便 。

Objective: To explore the application and related influential factors of the Revised Hasegawa's Dementia Scale (HDS-R) in screening senile dementia. Methods: A total of 1018 subjects who were older than 65-years old and permanently lived in the rural areas of three coastal counties of Guangdong province were screened for dementia using the HDS-R. Results: The scores of HDS-R ranged between 0 and 32.5 and the mean score was 23.5±5.80. The results of step-by-step regression analysis showed that age, gender, educational level, diagnosis of dementia, and hearing capacity were important influential factors of HDS-R. When the threshold score was 17, the sensitivity and the specificity were 95.1% and 97.7% respectively. Conclusions: HDS-R is easily operated and suitable for Chinese practice because of its higher sensitivity and specificity.
