Broadly consistent with the concurrent analyses, higher scores on Neuroticism, Extraversion, and Openness were associated with being heavier, whereas higher scores on Agreeableness and Conscientiousness were associated with being leaner. Most of the facets that had a significant effect on the intercept followed their domain-level associations. There were, however, a few notable exceptions. Although N2: Hostility, N3: Depression, and N5: Impulsiveness were associated with higher BMI, N6: Vulnerability was not related to BMI. In addition, participants higher on C1: Competence had higher BMI, whereas most of the other facets within Conscientiousness were associated with lower BMI. Of note, with the exception of E4: Activity, all of the associations between personality and the intercept of BMI replicated the concurrent analyses.
