Obesity is associated with impaired health-related quality of life (QoL) and reduced productivity; less is known about the effect of dietary factors. This study investigated how dietary behaviors, physical activity, and Body Mass Index (BMI) relate to weight-specific QoL and work productivity. The study was conducted in 31 small blue-collar and service industry worksites in Seattle. Participants were 747 employees (33.5% non-White). Measures included self-reported servings of fruits and vegetables, dietary behaviors such as fast food consumption, Godin free-time physical activity scores, measured height and weight, Obesity and Weight Loss Quality of Life (OWLQOL) scores, and Work Limitations Questionnaire (WLQ) scores. Baseline data were analyzed using linear mixed models separately for men (n=348) and women (n=399), since gender modified the effects. BMI was negatively associated with OWLQOL in both women (p<0.001) and men (p<0.001). The linear effect estimate for OWLQOL score associated with one-category increase in BMI was 30% (95% CI: 25%, 44%) for women and 14% (95% CI: 10%, 17%) for men. BMI was positively associated with productivity loss only in women (exp(slope)=1.46, 95% CI: 1.02, 2.11, p=0.04). Eating while doing another activity was negatively associated with OWLQOL scores in men (p=0.0006, independent of BMI) and with productivity in women (p=0.04, effect diminished when adjusting for BMI). Fast food meals were associated with decreased productivity for men (p=0.038, independent of BMI). Results suggest the obesogenic dietary behaviors and higher BMI are associated with decreased QoL and productivity variously in women and men.
