Previous research suggests that common modifiable health risk factors (e.g., depression, anxiety, metabolic illness, inflammation) may have an impact on memory. In the present study, we sought to investigate relationships between a number of these health risk factors and two components of recognition memory (recollection and familiarity). Data were analyzed for 96 healthy young adults between 17 and 25 years old. Recollection and familiarity were measured using an associative recognition procedure involving unitized and unrelated word pairs, and regression analyses were used to relate recognition memory performance to physical health (inflammation via plasma IL-6 levels, central obesity via waste-to-hip ratio, and heart rate variability) and mental health (depression via CESD-R, stress via PSS, and state and personality trait anxiety via STAI) measures of modifiable risk factors. Together, these health variables predicted an additional 19% of the variance in recollection beyond what was accounted for by familiarity, and 15% of the variance in familiarity beyond what was accounted for by recollection. These effects were primarily driven by inflammation, depression, and trait anxiety, which were each significant ( < .05) independent predictors of recognition. Higher levels of depression and inflammation were related to worse recollection yet better familiarity. Higher levels of trait anxiety were related to better recollection but were not related to familiarity. These findings demonstrate complex relationships between these modifiable health risk factors and recognition memory. Future longitudinal and cross-sectional research is needed to further explore these relationships and determine whether or not poor health causes these changes in recognition.
先前的研究表明，常见的可改变的健康风险因素（例如，抑郁、焦虑、代谢疾病、炎症）可能对记忆产生影响。在本研究中，我们试图研究这些健康风险因素中的许多因素与两种识别记忆成分（再认和熟悉度）之间的关系。对 96 名年龄在 17 至 25 岁之间的健康年轻成年人进行了数据分析。使用涉及单元化和非相关词对的联想识别程序来测量再认和熟悉度，回归分析用于将识别记忆表现与身体健康（通过血浆 IL-6 水平测量炎症，通过腰臀比测量中心性肥胖，通过心率变异性测量心理健康）和心理健康（通过 CESD-R 测量抑郁，通过 PSS 测量压力，通过 STAI 测量状态和人格特质焦虑）相关联。这些健康变量共同预测了再认的方差增加了 19%，熟悉度的方差增加了 15%，而这两个变量的方差增加了 19%。这些影响主要是由炎症、抑郁和特质焦虑驱动的，它们都是识别的重要（ <.05）独立预测因子。较高的抑郁和炎症水平与较差的再认有关，但与更好的熟悉度有关。较高的特质焦虑与更好的再认有关，但与熟悉度无关。这些发现表明这些可改变的健康风险因素与识别记忆之间存在复杂的关系。需要进行未来的纵向和横断面研究来进一步探索这些关系，并确定健康状况不佳是否导致识别能力的这些变化。
