Objectives: This study reports on the feasibility of the SitLess with MS trial, an intervention targeting sedentary behavior in individuals with multiple sclerosis (MS).
Design: Single group, pre-post intervention design.
Setting: Community.
Participants: Participants (N=41) with mild to moderate disability from MS.
Intervention: The intervention was 15 weeks, with a 7-week follow-up, and included 2 stages: SitLess and MoveMore. During the SitLess stage, participants were encouraged to break up prolonged sitting bouts over a 7-week period, whereas the MoveMore stage promoted increased steps per day and interrupting sitting over a 7-week period. The intervention was delivered through weekly one-on-one coaching sessions via telerehabilitation and an accompanying newsletter based on social-cognitive theory. Activity was monitored throughout the program using a Fitbit.
Main Outcome Measures: Process (eg, recruitment) and resource and management (eg, personnel requirements) metrics were assessed, along with efficacy outcomes (eg, effect). Progression criteria were set a priori and were related to safety, fatigue, satisfaction, and attrition. Sedentary behavior, measured using the ActivPal, was reported pre- and postintervention, as well as 7 weeks postintervention. Effect sizes (pre to post, pre to 7 weeks post) were calculated for the sedentary behavior outcomes (eg, time sitting, transitions from sitting to standing, number of long sitting bouts). Experiences with the intervention were explored through an online survey.
Results: Forty-one participants enrolled, 39 of whom completed the intervention. All participants but 1 were satisfied with the experience. Pre-post intervention effect sizes for change in total sedentary time, number of transitions from sit to stand, and number of long (>30 min) sedentary bouts were 0.34, 0.02, and 0.39 respectively. All a priori progression criteria were met.
Conclusions: The SitLess with MS program, a novel intervention that emphasized and facilitated sitting less and moving more, was feasible and resulted in small changes in sedentary behavior in individuals with MS.

Background: Increased burden of socially determined vulnerabilities (SDV), which include nonmedical conditions that contribute to patient health, is associated with incident heart failure (HF). Mediators of this association have not been examined. We aimed to determine if a healthy lifestyle mediates the association between SDV and HF.

Introduction: Despite increasing global migration, children from migrant backgrounds are underrepresented in physical activity research. This systematic review aimed to consolidate existing qualitative evidence on parental perceptions of the benefits, barriers, and facilitators of promoting physical activity and limiting sedentary behavior of their first- or second-generation migrant children aged 0-6 years.
Methods: Six electronic databases (Medline, CINAHL, PsycINFO, SPORTDiscus, Global, and Health EMBASE) were searched for qualitative peer-reviewed English language studies using terms covering migrants, parents, perceptions, physical activity, and sedentary behavior.

It is well-known that not meeting the movement guidelines, including insufficient physical activity (PA), excessive sedentary behavior (SB), inadequate sleep duration, and their combinations, are independent risk factors for noncommunicable diseases (NCDs). The prevalence of not meeting the guidelines is high across the world, especially in China where has one of the largest population. Some studies have estimated the economic cost of insufficient PA in China, which is useful to guide policymakers to develop and implement effective health actions.
