| 摘要: | Background： The global population is rapidly aging during recent years; the issue in relation to the elderly cognition has been widely discussed. There are many factors could affect the rate of elderly cognition decline. For instance, in-taking more fruits-vegetables, and have more physical activities could effectively reduce the risk of decline. However, the combinatorial effect of in-taking more fruits-vegetables and having more physical activities on the risk of elderly cognition decline at the same time is lack of discussion.
Objective: The object of this study was to explore the combinatorial effect of in-taking higher fruits-vegetables, and having more physical activity on risk of cognitive decline to elder people in Taiwan.
Method：This study implemented the database of the "Taiwan Longitudinal Survey on Aging (TLSA) from 1999 to 2007". 4,440 samples were collected in 1999 and excluded the samples which cannot be considered by the study, such as people who already have had cognitive decline, cancer, and passed away during the research period. There were 1,138 samples which were used. The study conducted that logistic regression with the following factors fixed: demographic variables, socioeconomic, health behavior, disease and other variables in order to analyze the longitudinal association that how much amount of in-taking fruits-vegetables and physical activities are enough to influence the risk of elder cognitive decline during eight years (the recession is defined in terms of the index of SPMSQ in 2007 reduces over 2 points in the comparison of the index in 1999).
Results：The elder who had lower in-take fruit-vegetable and physical activity, the risk of having cognitive decline is 69% higher than (OR=0.31, 95%; CI=0.16-0.58, P<0.001) the elder who had higher in-take fruit-vegetable and physical activity. There is no statistical significance, when only one factor is considered independently.
Conclusion：The result shows that the correlation between elder cognitive decline and the intake of fruits-vegetables and physical activity is significantly in the negative way. In other words, the risk of cognitive decline can be reduced when elder in-taking more fruits-vegetables and having more physical activity. Therefore, people should be encouraged to increase their intake of fruits-vegetables and have more physical activities in order to reduce the risk of elder cognitive decline. |
