In this article, we examine and reconsider the relationship between Body Mass
Index (BMI) and night work, and we analyze specically the moderating role of selfcontrol
in this relationship. Using a German panel data set of 13,146 individuals
followed between 2007 and 2014, we nd signicant cross-sectional correlations between
evening and night work and BMI. However, xed-eect regressions show that
transitioning from a regular working schedule to evening and night work has a signi
cant impact on body mass index, only for those individuals who score high on an
impulsiveness scale and are assigned to irregular evening and night work schedules.
Transitions to regular evening and night shifts have no eect on BMI. Additional
regressions reveal that the result may be explained by changes in the propensity to
implement health-conscious diet but are unrelated to changes in physical exercises.
Our results are line with predictions of self-control theory about the role of trait impulsiveness
and environmental factors in self-control depletion and impulsive behaviors.
