Background: Movement behaviors (i.e., physical activity [PA], sedentary behaviors [SB], sleep) relate to mental health. Although movement behaviors are often analyzed as distinct entities, they are in fact highly inter‐dependent (e.g., if an individual increases sleep, then PA and/or SB must be reduced) and these dependencies should be accounted for in the analysis. We tested whether perceptions of time spent in movement behaviors (i.e., moderate‐to‐vigorous intensity PA [MVPA], light physical activity [LPA], SB, and sleep) related to depressive symptoms and self‐report mental health in young adults using a compositional analysis. We then estimated change in depressive symptoms with reallocation of time across movement behaviors using compositional time‐reallocation models. Methods: Data were drawn from the longitudinal NDIT dataset. Complete data were available for 770 young adults (Mage = 20.3, 55% females). Results: The proportion of time spent in MVPA relative to other movement behaviors related to depressive symptoms non‐significantly and to mental health significantly. Reallocating 15 min from MVPA to SB resulted in a significant (0.46 unit) increase in depressive symptoms, and reallocating 15 min of MVPA to LPA was associated with a (0.57) increase in depressive symptoms. Conclusion: These results indicate the importance of relative time spent in each movement behavior to mental health. Further research should examine these associations over time.

Underuse of best practices in chronic disease prevention (CDP) represents missed opportunities to promote healthy living and prevent chronic disease. Better understanding of how CDP programs, practices and policies (PPPs) are transferred from ‘resource' organizations that develop them to ‘user' organizations that implement them is crucial. The objectives of this work were to develop psychometrically sound measures of transfer practices occurring within resource organizations; describe the use of these transfer practices and identify correlates of the transfer process. Cross-sectional data were collected in structured telephone interviews with the person most knowledgeable about PPP transfer in 77 Canadian organizations that develop PPPs. Independent correlates of transfer were identified using multiple linear regression. The transfer practices most commonly used included: identification of barriers to PPP adoption/implementation, tailoring transfer strategies and designing a transfer plan. Skill at planning/implementing transfer, external sources of funding specifically allocated for transfer, type of resource organization, attitude toward process of collaboration and user-centeredness were all positively associated with the transfer process. These factors represent possible targets for interventions to improve transfer of CDP PPPs. [ABSTRACT FROM PUBLISHER]
