Abstract
Background: Job strain has been reported as a trigger for binge eating, yet the underlying mechanisms have been
unclear. The aim of this study was to evaluate whether work-family conflict is a pathway in the association between
job strain and binge eating, considering the possible effect-modifying influence of body mass index (BMI).
Methods: This cross-sectional analysis included 12,084 active civil servants from the multicenter Brazilian Longitudinal
Study of Adult Health (ELSA-Brasil). Job strain was assessed using the Demand-Control-Support Questionnaire.
Work-family conflict was considered as a latent variable comprising three items. Binge eating was defined as eating
a large amount of food in less than 2 h at least twice a week in the last six months with a sense of lack of control over
what and how much was eaten. Structural equation modelling was used to test the role of work-family conflict in the
association between job strain and binge eating, stratifying for BMI.
Results: For individuals of normal weight, positive associations were found between skill discretion and binge eating
(standardized coefficient [SC] = 0.209, 95%CI = 0.022–0.396), and between psychological job demands and workfamily
conflict (SC = 0.571, 95%CI = 0.520–0.622), but no statistically significant indirect effect was found. In overweight
individuals, psychological job demands, skill discretion, and work-family conflict were positively associated
with binge eating (SC = 0.099, 95%CI = 0.005–0.193; SC = 0.175, 95%CI = 0.062–0.288; and SC = 0.141, 95%CI = 0.077–
0.206, respectively). Also, work-family conflict was observed to be a pathway on the associations of psychological
job demands and decision authority with binge eating (SC = 0.084, 95%CI = 0.045–0.122; and SC = − 0.008,
95%CI = − 0.015– − 0.001, respectively).
Conclusions: Work-family conflict partly explains effects of high levels of psychological job demands and low levels
of decision authority on binge eating among overweight individuals. Moreover, skill discretion is positively associated
with binge eating, regardless of BMI category.
