Mindfulness-based Lifestyle Modification Programme for Caregivers of People With Neurodegenerative Disorders: A Pilot Randomised Controlled Trial

Краткое описание

Over 80% of caregivers for individuals with neurodegenerative diseases (ND) engage in significant risk behaviors, particularly physical inactivity, which increases the risk of cardiometabolic diseases (CMD) by 30% and reduces life expectancy by 4-8 years. Despite the health benefits of maintaining healthy behaviors, awareness of behavioral risk management among healthcare professionals and the public is low, and research on this topic for ND caregivers is limited. Given that physical activity (PA) is the most prevalent modifiable risk factor, timely intervention is essential. International guidelines prioritize PA as a key strategy for caregiver health. However, existing PA interventions often struggle with low compliance due to the physical and emotional challenges caregivers face. Our research group actively explores the health-regulating and enhancing effects of integrative mind-body modalities, particularly mindfulness, which may promote and sustain healthy behaviors by improving attentional regulation and psychological flexibility. Mindfulness-based lifestyle modification might help caregivers better manage physical discomfort, stress, and self-limiting beliefs, thereby supporting sustained PA. The World Health Organization advocates for non-communicable disease (NCD) prevention through brief lifestyle interventions, such as ecological momentary interventions (EMI), which use mobile messaging (e.g., WhatsApp) to deliver personalized health content. This method is particularly valuable for caregivers who find it difficult to access traditional services due to their responsibilities. This pilot randomized clinical trial aims to evaluate the feasibility and acceptability of an EMI-enhanced "Brief and Blended Mindfulness-based Lifestyle Counselling Programme" (B-Mindful-Life) compared to brief lifestyle education for increasing PA among Chinese ND caregivers. The primary outcome will be the feasibility (rates of recruitment, eligibility, refusal, and retention at 2 and 5 months), and acceptability measures (adherence, incidence of adverse events, and satisfaction with intervention).
