Daytime sleepiness is highly prevalent in middle-aged adults and has a detrimental impact on their quality of life. Our study examined the psychological and behavioral determinants of daytime sleepiness among adults aged 35 to 64 years. The main variables of interest were psychological factors (perceived stress and anxiety), physical activity factors (moderate-to-vigorous physical activity and sedentary behaviors), and dietary factors (fat, sugar, fruit, and vegetable intake). Partial correlation and multiple linear regression were conducted to determine their associations with daytime sleepiness, with adjustment for covariates. Our sample included 87 adults with a mean age of 47 ± 9 years. About 21% met the criterion for excessive daytime sleepiness. Greater anxiety, longer time spent in sedentary behaviors, and higher consumption of foods rich in trans fat, sugar, and calories were independently associated with higher daytime sleepiness levels. Targeted interventions or treatments are warranted to address the identified risk factors for middle-aged adults.
