In addition, our analysis of weight fluctuations informs the association between antagonism and weight gain. As noted above, consistent with previous research on anger-related traits, antagonism was associated with weight gain across adulthood. The fluctuation analyses, however, indicated that antagonism was unrelated to deviations in weight. Taken together, these two sets of analyses suggest that antagonistic individuals gradually gain weight over time rather than gaining and losing, as is the case with other traits.
