Background: Many studies have attempted to mitigate the negative health consequences of sedentary behavior (SB) in the work environment using standing desks. However, no studies have explored the use of standing desks in the home. Purpose: To evaluate interest, factors influencing desk usage, and acceptability of a low-cost standing desk in the home. Methods: Participants (adults aged 18-65 years living in university residential areas) received a low-cost standing desk, and completed online surveys at baseline and 4 weeks to assess leisure SB. After 4 weeks, participants completed a phone interview to assess level of engagement and acceptability. A follow-up interview was conducted at 6 months. A descriptive content analysis was conducted. Results: A total of 71 participants were recruited, with 55 and 49 participants completing the 4-week and 6-month interview, respectively. At 4 weeks, there was a self-reported decline in weekday leisure SB (P < .05), but not on weekend days. Approximately 75% of interviewed participants reported using the desk every week. After 6 months, 21 participants (30%) were still using the desk. Conclusion: This study indicates interest in using standing desks in the home. Future research could examine the behavioral and health impact of SB interventions in this setting.

Background: Ecological momentary assessment (EMA) is a method of collecting behavioral data in real time. The purpose of this study was to examine EMA compliance, identify factors predicting compliance, assess criterion validity of, and reactivity to, using EMA in a workplace intervention study. Methods: Forty-five adults (91.1% female, 39.7 [9.6] y) were recruited for a workplace standing desk intervention. Participants received 5 surveys each day for 5 workdays via smartphone application. EMA items assessed current position (sitting/standing/stepping). EMA responses were time matched to objectively measured time in each position before and after each prompt. Multilevel logistic regression models estimated factors influencing EMA response. Cohen kappa measured interrater agreement between EMA-reported and device-measured position. Reactivity was assessed by comparing objectively measured sitting/standing/stepping in the 15 minutes before and after each EMA prompt using multilevel repeated-measures models. Results: Participants answered 81.4% of EMA prompts. Differences in compliance differed by position. There was substantial agreement between EMA-reported and device-measured position (κ = .713; P < .001). Following the EMA prompt, participants sat 0.87 minutes more than before the prompt (P < .01). Conclusion: The use of EMA is a valid assessment of position when used in an intervention to reduce occupational sitting and did not appear to disrupt sitting in favor of the targeted outcome.

Background: Physical activity (PA) is critical to early child development, and child care is a key setting for promotion. The authors investigated differences in daily PA and sedentary behavior practices as well as physical environments between family child care (FCC) and group child care (GCC) settings for children aged 3–5 years in Canada. Methods: Group child care (n = 581) and FCC (n = 357) managers completed surveys assessing the implementation of PA promoting practices and description of their environments. Crosstabulation and chi-square tests of association were used to examine differences between GCC and FCC. Results: The prevalence of facilities implementing 120 minutes of active play (odds ratio [OR] 2.23; 95% confidence interval [CI], 1.58–3.15), <30 minutes on screens (OR 1.35; 95% CI, 1.02–1.80), and 60-minute outdoors daily (OR 1.99; 95% CI, 1.4–2.9) was more likely in FCC compared with GCC. However, implementation of fundamental movement skill activities (OR 1.40; 95% CI, 1.01–1.92), breaking up prolonged sitting (OR 1.86; 95% CI, 1.36–2.5), and outdoor space for large group running games (OR 1.74; 95% CI, 1.07–2.83) were more likely in GCC. Conclusions: Child care setting was associated with daily PA and sedentary practices and outdoor space for PA. Interventions to support PA in child care should be tailored to different settings and the facilitators explored.
