Resumo
Abstract Physical inactivity during pregnancy is problematic and associated with adverse health outcomes, including increased blood loss during labor and pre-eclampsia. The purpose of the present study was to apply the behavioral economic framework to understand physical inactivity among pregnant women. We examine the factor structure of a novel hypothetical purchase task for physical inactivity in a cross-sectional survey study, as well as examine differences in the latent variable scores in a convenience sample of two distinct populations ( n = 68): pregnant veterans and nonveterans. Results showed that the purchase task was characterized by two latent factors: amplitude (i.e., intensity of demand for physical inactivity, α = 0.5) and persistence (i.e., demand sensitivity regarding physical inactivity, α = 0.9). After controlling for relevant demographic variables using linear regression analysis, veterans—compared to nonveterans—exhibited higher persistence (b = 1.6, p < 0.001) and amplitude scores (b = 1.2, p < 0.001). In summary, this study characterized a new behavioral economic measure of physical inactivity for pregnant women. Furthermore, we suggest that pregnant veterans may value physical inactivity more than pregnant nonveterans.
