Reducing sedentary behaviour and cognitive function in community-dwelling older people: Study protocol for a randomized feasibility study

(1) Background: Sedentary behaviour is high amongst older adults and increases with ill-health and cognitive impairment. Although there is strong evidence of the deleterious effects of high sedentary levels on cardiovascular health, its role and risk to cognitive health is inconclusive. In light of the recent lockdown and COVID-pandemic, the use of web-based health promotion amongst older adults has become more pertinent to attaining healthier living. Therefore, this study proposes to test the feasibility of an online health coaching intervention in people aged 50+ with mild cognitive impairment (MCI). (2) Methods: This is a 13-week unblinded, single-centre randomized feasibility study. People with MCI who meet study criteria (50+ years and MCI diagnosis) will be recruited from community settings nationwide. Participants will be randomized to receive online coaching or health information. The study reporting will follow the CONSORT statement. Primary outcomes will be feasibility of study and acceptability of online coaching intervention. (3) Discussion: It is hoped that if the intervention is feasible and acceptable, the study will progress to a definite large-scale study to evaluate clinical and cost-effectiveness.
