Association of sleep adequacy with more healthful food choices and positive workplace experiences among motor freight workers.

OBJECTIVES We assessed whether adequate sleep is linked to more healthful eating behaviors among motor freight workers and whether it mediates the effects of workplace experiences. METHODS Data were derived from a baseline survey and assessment of permanent employees at 8 trucking terminals. Bivariate and multivariate regression models were used to examine relationships between work environment, sleep adequacy, and dietary choices. RESULTS The sample (n = 542) was 83% White, with a mean age of 49 years and a mean body mass index of 30 kg/m(2). Most of the participants were satisfied with their job (87.5%) and reported adequate sleep (51%); 30% reported job strain. In our first model, lack of job strain and greater supervisor support were significantly associated with adequate sleep. In our second model, educational level, age, and adequate sleep were significantly associated with at least 2 of the 3 healthful eating choices assessed (P < .05). However, work experiences were not significant predictors of healthful food choices when adequate sleep was included. CONCLUSIONS Adequate sleep is associated with more healthful food choices and may mediate the effects of workplace experiences. Thus, workplace health programs should be responsive to workers' sleep patterns.
