Conclusion
A wide array of social and behavioral factors play a significant role in reports of insufficient sleep, as it is experienced in a large, diverse, nationally representative sample. Overall, the variable most closely related to insufficient sleep was general mental health, though other variables, such as general physical health, age, race/ethnicity, emotional support, and household size, were also robustly associated with insufficient sleep. Overall, the social and behavioral determinants examined in this study accounted for approximately 17–20% of the variance of insufficient sleep, leaving room for future studies aimed at further clarifying which factors are most strongly related to insufficient sleep in the general population. These data may be useful for developing and targeting interventions to alleviate the increased risk of morbidity and mortality.
