The associations between personality and weight were consistent across the different measures of adiposity (see Table 2).1 This consistency was not surprising given that the four different measures of adiposity were highly intercorrelated (median r = .87; range .78 to .94). At the broad domain level, controlling for demographic variables (sex, age, age squared, ethnicity, and education), participants higher on Neuroticism or Extraversion had greater adiposity, as assessed through either global (e.g., BMI) or central (e.g., waist circumference) measures. In addition, those higher in Conscientiousness were leaner, as assessed through either global or central measures of adiposity. Although the categorical analyses suggested that there may be a curvilinear association between personality and adiposity, we did not find such an association between BMI and any of the five traits in the continuous analyses.
