Sleep, Activity, and Nutrition Among an Army Sample: Strengths, Deficits, and Demographic Differences

Sleep, activity, and nutrition (SAN) are key components in overall health, and an individual’s knowledge about and self-confidence to engage in healthy SAN behaviors can have an impact on their actions. This evaluation examined SAN knowledge, self-confidence, and behaviors among U.S. Army Soldiers prior to participating in a health promotion program. Baseline surveys from participating Soldiers provide evidence in this evaluation. U.S. Army Soldiers ( N = 11,485) participating in a health promotion program completed surveys. Participants completed an online survey assessing SAN knowledge, self-confidence, and behaviors (among other constructs). We examined the common patterns of SAN behaviors, the associations between them, and the differences based on gender and rank. Knowledge, self-confidence, and behaviors were correlated within each of the three SAN domains. Men reported more aerobic exercise ( d = .48) and more resistance training ( d = .34) per week than women. Officers reported greater self-confidence in their ability to consume a post-exercise snack (i.e., refuel; d = .38), greater refueling behaviors ( d = .43), greater activity knowledge ( d = .33), and greater self-confidence in their ability to achieve activity goals ( d ranging from .33 to .39), compared to enlisted Soldiers. Finally, greater confidence in one’s ability to achieve healthy sleep correlated with getting more sleep, both during workweek ( r = .56, p
