The National Center for Advancing Translational Sciences (NCATS) has defined translation as the process of turning observations into interventions that are adopted, sustained, and improve health. Translation must attend to research and community systems and context at multiple levels, and to key stakeholders. Dissemination and implementation (D&I) sciences are informed by an understanding of the critical role of people and systems in disseminating, adopting, and sustaining innovations within real-world settings. Thus, the D&I sciences provides a set of principles that can guide the translational work of Clinical and Translational Science Award (CTSA) programs from basic research to public health. In this special communication, our cross-domain working group of the CTSA consortium, comprised of experts in methods and processes, workforce development, evaluation, stakeholder engagement, and D&I sciences, share a vision of how CTSAs can enhance translation across the translational spectrum through the integration of D&I sciences into the critical areas of methods and processes, workforce development, and evaluation. We propose a set of recommendations for NCATS national and local leaders that are intended to move D&I sciences out of a position of unfamiliarity and ancillary value and into the core identity of who CTSAs are, how they think, and what they do, to advance translation and health.

Background: The objective of this paper is to derive a wrist-placed cut-point threshold for distinguishing sedentary behaviors from light-intensity walking using the ActiGraph GT3X+ in children. Methods: This study employed a cross-sectional study design, typically used in measurement-related studies. A sample of 167 children, ages 5-11 years (mean ± SD: 8.0 ± 1.8 years), performed up to eight seated sedentary activities while wearing accelerometers on both wrists. Activities included: reading books, sorting cards, cutting and pasting, playing board games, eating snacks, playing with tablets, watching TV, and writing. Direct observation verified sedentary behavior from light activity. Receiver operator characteristic (ROC) analyses were used to determine optimal cut-point thresholds. Quantile regression models estimated differences between dominant and non-dominant placement. Results: The optimal cut-point threshold for the non-dominant wrist was 203 counts/5 s with sensitivity, specificity, and area under the curve (AUC) of 71.56, 70.83, and 0.72, respectively. A 10-fold cross-validation revealed an average AUC of 0.70. Statistically significant (p ≤ 0.05) differences in median counts ranging from 7 to 46 counts/5 s were found between dominant and non-dominant placement in five out of eight sedentary activities, with the dominant wrist eliciting higher counts/5 s. Conclusion: Results from this study support the recommendation to place accelerometers on the non-dominant wrist to minimize "noise" during seated sedentary behaviors.

State and national organizations recently developed policies focused on increasing physical activity (PA) in afterschool programs (ASPs). These policies emphasize "activity friendly" environment characteristics that, when present, should lead to higher levels of PA and reduce the amount of time children spend sedentary during an ASP. Currently, little is known about the impact of existing PA policies on children's PA and sedentary behaviors in ASPs. A sample of 18 community-based ASPs serving 1,241 children (5-12 years) were audited for environment features outlined in existing PA policies (i.e., presence of a written policy to promote PA, collecting child feedback, staff training to promote PA and the quality of that training, holding parent workshops, use of PA curricula, evaluating PA, allocating time in the schedule for PA opportunities, and providing activities that appeal to both boys and girls). Children's PA and sedentary behavior were measured via accelerometry. Unexpectedly, the presence of a written policy, collecting child feedback, and receiving 1 to 4 hours of staff training for PA was associated with an increase in time spent sedentary and a decrease in PA. Conversely, allocating 50% or more time in an ASP schedule for PA and providing activities that appealed to boys and girls was associated with a decrease of time spent sedentary and an increase in PA. The present state of practice in ASPs suggests that policy environment characteristics are largely unrelated to the amount of PA children accumulate while attending ASPs.
