The main objective of this study was to examine the relationships among demographic characteristics, depressive symptoms, and cognitive impairment in oldest-old elders from rural areas of the Brazilian State of Rio Grande do Sul.
A cross-sectional, descriptive correlational design was used to conduct the study.
137 Brazilian elders age 80 years or over.
A target population data form, a county data form, a demographic questionnaire, the Mini-Mental State Examination, and the Depressive Cognition Scale were used to collect the data.
A significant difference was found between males and females in regard to cognitive impairment. In addition, educational level and depressive symptoms were correlated with cognitive impairment. Depressive symptoms were a weak but significant predictor of cognitive impairment after controlling for the effect of age, gender, and educational level of the oldest-old elders.
The findings need to be interpreted cautiously since the sample scored above the cutoff points for cognitive impairment, and had low scores on depressive symptoms. Despite several limitations, findings from this study can be a foundation for further studies, and well-designed correlational or experimental approaches, are warranted.
本研究的主要目的是考察巴西南里奥格兰德州农村地区高龄老年人的人口统计学特征、抑郁症状与认知障碍之间的关系。
采用横断面描述性相关设计进行本研究。
137名80岁及以上的巴西老年人。
使用目标人群数据表、县数据表、人口统计问卷、简易精神状态检查表和抑郁认知量表收集数据。
在认知障碍方面，男性和女性之间存在显著差异。此外，教育水平和抑郁症状与认知障碍相关。在控制了高龄老年人的年龄、性别和教育水平的影响后，抑郁症状是认知障碍的一个微弱但显著的预测因素。
由于样本的认知障碍得分高于临界值，且抑郁症状得分较低，因此对研究结果的解释需要谨慎。尽管存在若干局限性，但本研究结果可为进一步研究奠定基础，且有必要采用精心设计的相关或实验方法。
