Feasibility and Preliminary Efficacy of an m-Health Intervention Targeting Physical Activity, Diet, and Sleep Quality in Shift-Workers.

摘要: Poor health behaviors are prevalent in shift-workers, but few multiple health-behavior interventions consider their unique needs. This study aimed to (1) evaluate the feasibility and acceptability of an existing app-based intervention improve physical activity, diet, sleep quality a shift-worker population, (2) estimate effect four-week pilot randomized controlled trial (RCT) (ACTRN12618001785291). Shift-workers (18–65 years old) were (n = 20) or wait-list groups. Outcomes included recruitment, engagement, attrition, usefulness ratings, System Usability Scale (SUS), qualitative interviews, estimation treatment (minutes diet quality, quality) using mixed model analysis. Recruitment took one week. App-use at week four was 55% (11/20), 85% (34/40) completed follow-up questionnaire, 20% (4/20) group interview. The rated as slightly moderately useful by 76.9% (10/13) participants on five-point scale. SUS score 62.7 (12.7) out 100. Diet improved for (4.5 points; 95% confidence interval (CI) 0.1, 8.9; p 0.047) vs. group, not activity quality. Qualitative interviews found that more tailored intervention, accessible information, interactive features desired. feasible terms modifications increase engagement needed.
