BACKGROUND
Data on dementia from low- and middle-income countries are still necessary to quantify the burden of this condition. This multicenter cross-sectional study aimed at estimating the prevalence of dementia in 2 large cities of Central Africa.
METHODS
General population door-to-door surveys were conducted in the districts of Bangui (Republic of Central Africa) and Brazzaville (Congo) in elderly aged ≥ 65 years. The subjects were screened with the Community Screening Interview for Dementia and the Five-Words Test. Diagnosis of dementia was made according to the DSM-IV criteria and to the clinical criteria proposed by the NINCDS-ADRDA for Alzheimer's disease.
RESULTS
We enrolled 496 subjects in Bangui and 520 in Brazzaville. The prevalence of dementia was estimated at 8.1% (95% CI = 5.8-10.8) in Bangui and 6.7% (95% CI = 4.7-9.2) in Brazzaville.
CONCLUSION
The prevalence of dementia in urban areas of Central Africa is close to those observed in high-income countries.
背景
仍需要来自中低收入国家的痴呆症数据来量化这种疾病的负担。这项多中心横断面研究旨在估计中非两个大城市的痴呆症患病率。
方法
在中非共和国的班吉和刚果共和国的布拉柴维尔的城区进行了≥65 岁老年人的入户调查。采用社区痴呆筛查访谈和五词测试对受试者进行筛查。根据 DSM-IV 标准和 NINCDS-ADRDA 对阿尔茨海默病的临床标准诊断痴呆症。
结果
我们在班吉纳入了 496 名受试者，在布拉柴维尔纳入了 520 名受试者。班吉的痴呆症患病率估计为 8.1%（95%CI=5.8-10.8），布拉柴维尔的患病率估计为 6.7%（95%CI=4.7-9.2）。
结论
中非城市地区的痴呆症患病率接近高收入国家的观察结果。
