Whether physical activity (PA) tracking devices are associated with PA motivation in young adults is largely unknown. We compared total PA minutes per week, total minutes walking/week, meeting moderate-to vigorous PA guidelines, and past-year activity tracking across motivation cluster profiles among 799 young adults. Participants with "self-determined" profiles reported the highest total PA minutes/week followed by participants with "low intrinsic," "controlled self-determined," and "high external" profiles. A behavior regulation profile X activity tracking frequency interaction was not significant. Behavior regulation profiles may need to be considered in PA interventions using activity trackers.

The objectives of this study were to describe the cross-sectional associations between body-related self-conscious emotions and depressive symptoms in young adults and examine self-esteem as a moderator of these associations. Data from a population-based sample of 811 young adults were analyzed using hierarchical multivariate linear regression analysis. Body-related shame (β =.26) and guilt (β =.25) were positively related to frequency of depressive symptoms. Self-esteem was negatively related to frequency of depressive symptoms (β = −.46). Self-esteem moderated the association between body-related guilt and frequency of depressive symptoms. These findings suggest promoting self-esteem may help to reduce the negative effects of body-related guilt on depressive symptoms. [ABSTRACT FROM AUTHOR]
