AbstractBackgroundOlder females show greater cognitive gains from physical activity (PA) than males, which may be related to long-term consequences of female-specific reproductive events (eg, pregnancy) on cognitive health.MethodsTo determine whether previous parity could moderate the relationship between PA and cognitive decline in older women, we conducted secondary analyses of data from the Health, Aging, and Body Composition Study. We tested whether the association between average PA over 10 years and cognition (Modified Mini-Mental State Examination [3MS]) and executive functioning (digit symbol substitution test [DSST]) over 10 years varied by previous parity (nulliparity, low parity, medium parity, and grand multiparity). An analysis of covariance was performed with cognition (average and change over 10 years) as the dependent variables, parity as a categorical predictor, average PA as a continuous predictor, and a set of relevant covariates.ResultsSignificant interactions were found between PA and parity group for all 4 comparisons: average 3MS (p = .014), average DSST (p = .032), change in 3MS (p = .016), and change in DSST (p = .017). Simple slope analyses indicated the positive relationship between PA and average 3MS and DSST was only significant in the nulliparity and grand multiparity groups, and the positive relationship between PA and change in 3MS and DSST was only significant in the grand multiparity group.ConclusionThe findings suggest the relationship between self-reported walking and cognitive performance was strongest in the groups at risk for cognitive decline and dementia, the nulliparous and grand multiparous groups.

步行促进认知健康:先前的奇偶性调节了自我报告的步行与认知之间的关系

摘要背景与男性相比,老年女性从体力活动(PA)中获得的认知收益更大,这可能与女性特有的生殖事件(例如怀孕)对认知健康的长期影响有关。方法为了确定之前的生育情况是否可以调节老年女性 PA 与认知能力下降之间的关系,我们对健康、衰老和身体成分研究的数据进行了二次分析。我们测试了 10 年平均 PA 与 10 年认知(改良简易精神状态检查 [3MS])和执行功能(数字符号替换测试 [DSST])之间的关联是否因之前的奇偶性(无效性、低奇偶性、中等奇偶性)而变化。平价和大多重平价)。以认知(10 年平均和变化)作为因变量,奇偶性作为分类预测变量,平均 PA 作为连续预测变量以及一组相关协变量进行协方差分析。结果在所有 4 项比较中,PA 和奇偶组之间均发现显着的交互作用:平均 3MS (p = .014)、平均 DSST (p = .032)、3MS 变化 (p = .016) 和 DSST 变化 (p = .032)。 017)。简单斜率分析表明,PA 与平均 3MS 和 DSST 之间的正相关关系仅在未产妇组和大多产组中显着,并且 PA 与 3MS 和 DSST 变化之间的正相关关系仅在大多产组中显着。结论研究结果表明,在有认知能力下降和痴呆风险的群体、未产妇和多产妇群体中,自我报告的步行与认知表现之间的关系最强。
