摘要
目的确定加纳 50 岁及以上老年人语义记忆（SM）和外显记忆（EM）的相关因素：本研究使用了世界卫生组织全球老龄化与成人健康研究（SAGE）加纳第 2 波的数据。语义记忆（SM）和外显记忆（EM）分别是主要的研究结果。研究采用了嵌套普通最小平方回归分析法，依次增加 6 个变量组，并在嵌套模型之间进行比较测试：研究涉及 3575 名 50 岁及以上的加纳成年人，平均年龄（± 标准差）为 62.6 ± 18.4 岁。EM和SM的总体平均值（标准差）分别为5.86 ± 2.51和11.69 ± 8.59。69）、居住在大阿克拉地区（地区差异）（β = -3.45；95% CI = -4.73-2.20）、体重不足（β = -0.81；95% CI =-1.34-0.27）和中度自评健康（SRH）（β = -0.98；95% CI =-1.52-0.45）会显著降低 SM。同样，年龄增加、分居/离婚（β = -0.22；95% CI = -0.35-0.87）、居住在大阿克拉地区（β = -0.53；95% CI = -0.80-0.26）和中度自评健康（SRH）（β = -0.20；95% CI = -0.36--0.04）会明显降低 EM，总体显著差异约为 22.9%（ΔR2 = 2.7%）：结论：年龄、性别、婚姻状况、地区差异和性健康和生殖健康不良的增加会明显降低语义记忆和外显记忆。较高的教育程度和生活满意度对语义记忆和外显记忆有明显影响。这些研究指出了决定语义记忆和外显记忆的重要社会人口因素，对实施 2010 年加纳国家老龄化政策 "安全和有尊严地迈向老年 "具有重要意义，也是迈向 2030 年健康老龄化的关键因素。
Determinants of semantic and episodic memory decline among older adults in Ghana: Evidence from the WHO study on global AGEing and adult health Ghana wave 2.
Objective: Determined factors associated with semantic (SM) and episodic memory (EM) among older adults aged 50 years and older in Ghana.
Methods: Data from WHO Study on Global AGEing and Adult Health (SAGE) Ghana Wave 2 was used for this study. Semantic memory (SM) and Episodic memory (EM) were the main study outcomes separately. The study employed Nested Ordinary Least Square regression analysis by sequentially adding 6 blocks of variables and comparison tests between the nested models.
Results: The study involved 3575 adult Ghanaians aged 50 years and older with a mean ± standard deviation of 62.6 ± 18.4 years. The overall mean ± SD of EM and SM were 5.86 ± 2.51 and 11.69 ± 8.59 respectively. Overall, analysis from block 6 showed a significant variation in SM by approximately 16.9%(ΔR2 = 1.17%) where increasing age, never married (β = -1.55; 95% CI = -2.41-0.69), being resident in Greater Accra (regional disparity) (β = -3.45; 95% CI = -4.73-2.20), underweight (β = -0.81;95% CI = -1.34-0.27), and moderate self-rated health (SRH) (β = -0.98; 95% CI = -1.52-0.45) significantly decreased SM. Similarly, increasing age, separated/divorced (β = -0.22; 95% CI = -0.35-0.87), being resident in Greater Accra (β = -0.53; 95% CI = -0.80-0.26), and moderate SRH (β = -0.20; 95% CI = -0.36--0.04) significantly decrease EM with an overall significant variation of approximately 22.9%(ΔR2 = 2.7%).
Conclusions: Increasing age, sex, marital status, regional disparity, and poor SRH significantly decreased both Semantic memory and Episodic memory. Higher educational attainment and life satisfaction significantly influenced SM and EM. These provide pointers to important socio-demographic determinants of SM and EM with implications for the implementation of the Ghana national ageing policy 2010, 'ageing with security and dignity', and as a key consideration for healthy ageing towards 2030.
