Title: Intervention to Reduce Sedentary Time in Older Adults Undergoing Orthopaedic Surgery: a Feasibility Study (INTEREST)
Brief Summary: The aim of this study is to investigate the feasibility of an intervention to reduce sedentary behaviour in older adults waiting for hip and knee replacements. The study will be a randomised controlled trial design, including 2:1 randomisation into an intervention and usual care group respectively. A target of n=45 patients ≥60 years will be recruited from Russells Hall Hospital, Dudley, UK, approximately 8-10 weeks before surgery, assisted by research nurses. The variable-length intervention, informed by Self-Determination Theory (SDT), will be composed of multiple behaviour change techniques, namely motivational interviewing, individualised feedback on sedentariness, goal-setting, environmental modification, self-monitoring, and social support. Assessments will occur at baseline, 1 week pre-surgery, and 6 weeks post-surgery. The primary outcome will be the feasibility of the trial, assessed quantitatively using study statistics, and with mixed-methods assessment of acceptability, practicality, adaption, satisfaction, and safety via questionnaires given to participants. Exploratory outcomes will include physical function, cardiometabolic biomarkers, measurement of SDT constructs, and both objective and subjective measurement daily activity and sedentariness. The study will last up to 18 weeks per participant.


Options:
A: Study uptake rates (as % of those approached who are randomised, recruitment rates (N/mth) (Assessed post-study-endpoint (up to month 18)); Intervention adherence to goals (Assessed post-study-endpoint (up to month 18)); Percentage of participants whose surgery is scheduled up to 2 weeks prior to the end of the intervention (Assessed post-study-endpoint (up to month 18)); Percentage of participants whose surgery is scheduled up to three weeks after the end of the intervention (Assessed post-study-endpoint (up to month 18)); Percentage of participants whose surgery is cancelled or delayed for too long (Assessed post-study-endpoint (up to month 18)); Retention rates (% of participants randomised who provide data at follow-up) (Assessed post-study-endpoint (up to month 18)); Acceptability of intervention for participants (Pre-surgery (visit 4, up to week 10), post-surgery (visit 5, up to week 18)); Practicality of intervention for participants (Pre-surgery (visit 4, up to week 10), post-surgery (visit 5, up to week 18)); Participant satisfaction with the study (Pre-surgery (visit 4, up to week 10), post-surgery (visit 5, up to week 18)); Patient perception of the safety of the study as assessed by questionnaire (Pre-surgery (visit 4, up to week 10), post-surgery (visit 5, up to week 18))
B: Change in objective total, light and moderate-to-vigorous physical activity (PA) (Pretest, posttest (6 weeks) and follow-up (6 months)); Change in objective sedentary behaviour (Pretest, posttest (6 weeks) and follow-up (6 months)); Change in self-reported total, light and moderate-to-vigorous physical activity (PA) (Pretest, posttest (6 weeks) and follow-up (6 months)); Change in self-reported sedentary behaviour (Pretest, posttest (6 weeks) and follow-up (6 months))
C: Functional performance, balance and reduced self-reported upper and lower body functional limitations in sedentary, older adults' physical activity. (Baseline, 6-month, 12-month follow-up)
D: Change in Fruit/Vegetable Serving Intake (3, 6, and 9 months); Change in Saturated Fat (% of daily calories from fat) Intake (3, 6, and 9-months); Change in Sedentary Leisure Screen Time (minutes/week) (3, 6, and 9-months); Change in Physical Activity (minutes/week) (3, 6, and 9-months); Change in Dietary Intake (3 and 9-months); Healthy Diet and Activity Improvement (3, 6, and 9 months)
