Understanding 24 Hour Activity, Sedentary Time and Sleep in Young Onset Dementia to Inform HEPA Strategies in Care Settings 1: Odisee University of Applied Sciences, Active Neighborhoods and Lifestyle Interventions, Brussels, Belgium; 2: University of Brussels, Mental Health research group, Brussels, Belgium Background Health care settings are pivotal to promote physical activity and wellbeing in people with young‑onset dementia (YOD). Evidence describing 24‑hour movement behaviours together with lived experiences in YOD remains limited. Methods This was a convergent mixed‑methods study in four care centres. Fifty‑six adults with YOD wore wrist accelerometers to assess sedentary time, activity intensities, steps and sleep (efficiency, total sleep time, awakenings). Ten focus groups explored sleep, emotions, coping, daytime functioning and support needs within care environments. Results Participants (ages 53–73 years) showed high sedentary time and low moderate-to-vigorous physical activity (MVPA), with many accumulating far below 10,000 steps/day, reflecting markedly inactive 24‑hour movement patterns. Sleep efficiency was generally high, yet several individuals experienced fragmented or short sleep, with long wake time after sleep onset (WASO) episodes influencing daytime energy. Qualitative findings revealed that these disrupted 24‑hour rhythms often interacted with emotional states, where early awakenings, rumination, or noise sensitivity reinforced feelings of uncertainty, frustration or sadness. Conversely, moments of good sleep or movement were linked to more stable mood and engagement. Participants used music, light activity, routines, and social interaction to regulate emotions and compensate for fatigue. Conclusions Health‑care settings should address YOD‑related inactivity and variable sleep–emotional patterns through personalised, low‑threshold HEPA approaches that embed social–emotional support, music‑ and movement‑based coping, and practical guidance on sleep and emotional self‑management, fostering consistent engagement and wellbeing. | |
