Cognition is integral for health and well-being. Modifiable health behaviors, such as physical activity and alcohol use, can have contrasting effects on cognition. Physical activity typically positively impacts cognitive health, while the relationship between alcohol use and cognition is more nuanced depending upon the intensity of use. Understanding the simultaneous impact of physical activity and alcohol use in middle adulthood is of interest as individuals transition to older adulthood. Whether from normal aging or pathological etiologies, cognitive decline is a significant personal and public health concern. Data from the Midlife in the United States (MIDUS) Waves 2 and 3 general and cognitive projects were analyzed. Participants (N=3,657; M age 56.4; 55.3% female) completed phone-based interviews assessing biopsychosocial factors related to physical and mental health, including past 30-day alcohol use, engagement in physical activity, and aspects of cognition - executive functioning, episodic memory, and a total composite. Individuals were classified as low or high-risk drinkers based on empirical guidelines using quantity and frequency data. The scope of physical activity was narrowed to include moderate or vigorous leisure-time physical activity (LPA). General linear models assessed the relationship of LPA and drinking status on cognition cross-sectionally (MIDUS 2) and longitudinally (change over time; MIDUS 2 to MIDUS 3), controlling for demographic and health variables. Baseline LPA (assessed at MIDUS 2) was positively and robustly associated with better cognition cross-sectionally and with less cognitive decline over time. An increase in LPA From MIDUS 2 to MIDUS 3 was associated with less executive functioning decline; however, the effects on episodic memory and total cognition were non-significant. The effect of drinking status was non-significant cross-sectionally and longitudinally. Results provide evidence for a robust positive relationship between physical activity and cognition and should be considered for cognitive health interventions. The non-significant findings between drinking status and cognition are likely due to the nuanced alcohol-cognition relationship and the limited range of heavy drinking exhibited by the high-risk drinkers in this general population sample. The effects of greater alcohol consumption and the interaction of LPA and drinking status at varying intensities of engagement warrant further investigation.
