Abstract
Purpose: To investigate the association among different intensity and duration of physical activity (PA), cognitive domains (executive function, processing speed, and memory), and demographic and lifestyle characteristics of aging Hispanic population. PA has been identified as a promising non-pharmaceutical preventative intervention for Alzheimer disease and other dementias. This study aims to provide a better understanding of the effects of different intensities of PA on cognitive performances of aging Hispanic population.
Methods: For this study, 441 Hispanic (age ≥60) participants’ data from NHANES (20112014) were analyzed. The protocol was approved by the NCHS Research Ethics Review Board, and all data collection performed by NHANES. Participants self-reported demographic, lifestyle, and health characteristics. The Global Physical Activity Questionnaire (GPAQ) was used for PA pattern, the frequency and duration of moderate intensity PA (MPA) and vigorous intensity PA (VPA) in a typical week, weekly PA was calculated from the product of the number of days by minutes per day and reported as minutes per week. American College of Sports Medicine (ACSM) guidelines were used for both VPA and MPA and for defining inactive, insufficiently active, sufficiently active categories for each intensity level. Participants completed cognitive performance assessment in verbal learning and memory (immediate / delayed), verbal fluency (animal fluency test (AFT)), and processing speed, sustained attention, and working memory (the Digit Symbol Substitution (DSS)) domains.
Results: Out of 441 participants, 225 were female (age= 66.83±5.49 yr.) and 216 were male (age= 66.62±5.81 yr.). Based on reported total minutes of PA in a typical week, 83% and 37% of participants were placed in a physically inactive category for VPA and MPA, respectively. There was no significant difference in immediate recall and DSS assessment between VPA and MPA groups. VPA’s sufficiently active subgroup showed a trend to improve delayed recall scores/ delayed memory domain (p< 0.1). MPA’s sufficiently active subgroup showed significantly improved scores in the AFT/ executive function domain (p< 0.01), compared to physically inactive group. Gender and education level were positively, age and depression state were negatively correlated with cognitive performances. There was a positive relationship among HDL and immediate / delayed, AFT, and DSS tests.
Conclusions: The findings of the study indicated that magnitude of impacts and the degree of association between various PA intensities and different cognitive domain may vary. In addition, many aging Hispanic individuals reported that they are not physically active, and more than two thirds of the participants do not engage in enough vigorous activity. Therefore, caution is advised when interpreting the findings related to the effects of VPA on various cognitive domains. It should be also noted that the positive relationship between HDL levels and immediate / delayed, AFT, and DSS tests may be unique for Hispanic population and demands further attention.
