Background: Endocannabinoids and temperament traits have been linked to both physical activity and body mass index
(BMI) however no study has explored how these factors interact in females. The aims of this cross-sectional study were to 1)
examine differences among distinct BMI groups on daytime physical activity and time spent in moderate-vigorous physical
activity (MVPA), temperament traits and plasma endocannabinoid concentrations; and 2) explore the association and
interaction between MVPA, temperament, endocannabinoids and BMI.
Methods: Physical activity was measured with the wrist-worn accelerometer Actiwatch AW7, in a sample of 189 female
participants (43 morbid obese, 30 obese, and 116 healthy-weight controls). The Temperament and Character InventoryRevised
questionnaire was used to assess personality traits. BMI was calculated by bioelectrical impedance analysis via the
TANITA digital scale. Blood analyses were conducted to measure levels of endocannabinoids and endocannabinoid-related
compounds. Path-analysis was performed to examine the association between predictive variables and MVPA.
Results: Obese groups showed lower MVPA and dysfunctional temperament traits compared to healthy-weight controls.
Plasma concentrations of 2-arachidonoylglyceryl (2-AG) were greater in obese groups. Path-analysis identified a direct effect
between greater MVPA and low BMI (b = 20.13, p = .039) and high MVPA levels were associated with elevated anandamide
(AEA) levels (b = 0.16, p = .049) and N-oleylethanolamide (OEA) levels (b = 0.22, p = .004), as well as high Novelty seeking
(b = 0.18, p,.001) and low Harm avoidance (b = 20.16, p,.001).
Conclusions: Obese individuals showed a distinct temperament profile and circulating endocannabinoids compared to
controls. Temperament and endocannabinoids may act as moderators of the low MVPA in obesity. [-]
