天津市社区老年人膳食模式与认知功能的关联

Association between dietary pattern and cognitive function of elderly in Tianjin

  • 摘要:
    目的 探讨社区老年人膳食多样性和膳食模式与认知功能的关联。
    方法 采用横断面研究,于天津市王顶堤社区单纯随机抽样 143名>65岁老年人,对参与者采用自行设计调查问卷获取膳食信息,并计算出膳食多样性指数;采用韦氏成人智力量表中国修订版测量智商值,评估认知功能。因子分析提取膳食模式,多元线性回归模型分析膳食多样性和膳食模式与老年人认知功能的关联。
    结果 因子分析得到4种膳食模式:肉谷类膳食模式、鱼禽奶制品膳食模式、豆类蔬菜膳食模式、蛋类膳食模式。多元线性分析结果显示,蛋类膳食模式与操作智商关联有统计学意义(P<0.05),即蛋类膳食模式可能对老年人操作智商具有一定保护作用。膳食多样性指数与老年人认知功能关联无统计学意义(P>0.05)。
    结论 遵循蛋类膳食模式可对老年人认知功能具有一定的保护作用,故日常饮食中老年人应适量增加对蛋类的摄入。

     

    Abstract:
    Objective To determine the association of dietary diversity and dietary pattern with cognitive function in elderly in community.
    Methods A cross-sectional study was conducted to randomly select 143 elderly people over 65 years old in Wangdingdi Community of Tianjin. Self-designed questionnaire was used and then dietary diversity index was calculated. Wechsler Adult Intelligence Scale-Chinese Revised (WAIS-RC) was used to measure intelligence quotient (IQ) to assess cognitive function. Factor analysis and multivariate linear regression model were used to extract dietary patterns and determine the association of dietary diversity index and dietary patterns with cognitive function, respectively.
    Results Factor analysis revealed four dietary patterns, which were meat and cereal dietary pattern, fish and poultry milk dietary pattern, bean vegetable dietary pattern, and egg dietary pattern. Multivariate linear regression showed that egg dietary pattern was significantly associated with performance IQ (P<0.05), suggesting that egg dietary pattern may have a protective effect on IQ of the elderly. There was no significant association between dietary diversity and cognitive function in the elderly (P>0.05).
    Conclusion Egg dietary pattern may protect cognitive function in the elderly. Therefore, the elderly should increase the intake of eggs in daily diet.
