The number of people living with dementia is growing worldwide and most rapidly in low- and middle-income countries. Little is known about dementia in Benin. We estimated the prevalence of dementia among retired people in Parakou, a northern city in Benin, and then assessed associated factors.
A cross-sectional study was performed in Parakou from July to August 2014. Participants were recruited at 2 centers, the National Center of Social Security and the Public Treasury of Benin. Participants with cognitive impairment were defined as having a low cognitive score (<7) for the brief version of the Community Screening Interview for Dementia and were invited to neurological examination. DSM-IV-TR criteria were used to diagnose dementia and the HACHINSKI score was used to differentiate dementia subtypes. A logistic regression model was performed to identify factors associated with dementia.
Overall, 440 retired people were included in the study. They were mainly male (92.3%) and their mean age was 64.9 ± 6.0 years. The prevalence of cognitive impairment was 7.7% (95% CI 5.2-10.2). Fourteen participants were diagnosed with dementia, representing a prevalence of 3.2% (95% CI 1.5-4.8). Alzheimer disease was the most frequent subtype (64.3%), followed by vascular dementia (21.4%). Retired people diagnosed with dementia were all men and were aged between 61 and 71 years. Most of them were living alone. The main factors associated with dementia were older age, low fruit and vegetables consumption, and living alone.
This study showed a low prevalence of dementia among retired older people in Benin. Despite this, greater attention must be given to the potential burden dementia places on families for better care, before the expected aging of the population becomes more significant.
全球范围内痴呆患者人数不断增加，且中低收入国家的增长速度最快。目前对贝宁的痴呆情况知之甚少。我们评估了贝宁北部城市帕拉库的退休人群中痴呆的患病率，并评估了相关因素。
2014 年 7 月至 8 月在帕拉库进行了一项横断面研究。参与者是在两个中心招募的，即贝宁国家社会保障中心和公共财政部。具有认知障碍的参与者被定义为社区痴呆筛查访谈简短版认知评分较低（<7），并被邀请进行神经检查。使用 DSM-IV-TR 标准诊断痴呆，使用 HACHINSKI 评分区分痴呆亚型。使用逻辑回归模型确定与痴呆相关的因素。
共有 440 名退休人员参与了研究。他们主要为男性（92.3%），平均年龄为 64.9±6.0 岁。认知障碍的患病率为 7.7%（95%CI 5.2-10.2）。14 名参与者被诊断为痴呆，患病率为 3.2%（95%CI 1.5-4.8）。阿尔茨海默病是最常见的亚型（64.3%），其次是血管性痴呆（21.4%）。诊断为痴呆的退休人员均为男性，年龄在 61 至 71 岁之间。他们大多独居。与痴呆相关的主要因素是年龄较大、水果和蔬菜摄入量低以及独居。
本研究表明，贝宁退休老年人痴呆的患病率较低。尽管如此，随着人口预期老龄化变得更加显著，必须更加关注痴呆给家庭带来的潜在负担，以便更好地提供护理。
