A secondary time-series analysis of the Behavioral and Environmental Sensing and Intervention (BESI) dataset examined how momentary home environmental conditions relate to agitation episodes reported by caregivers of persons with dementia living at home. Room-level sensors captured light, temperature, humidity, pressure, and noise/audio; agitation was measured with wrist-worn accelerometers. Generalized linear mixed models indicated higher noise and abrupt light changes significantly elevated agitation odds (p\u003C0.05), with bedroom and kitchen effects. Phase III caregiver-targeted interventions reduced agitation sensitivity to environmental volatility, suggesting real-time contextual feedback improves

Innovation in Aging, 2025, Vol. 9, No. S2  \n13 BESI deployments (Phase II: eight 30-day, Phase III: five 60-day). Environmental features, including light level, temperature, humidity, air pressure, and noise/audio features, were collected via room-level sensors. Agitation was captured using wrist-worn accelerometers. Caregivers provided timestamped agitation reports and contextual surveys. Data were harmonized across modalities using UNIX (a standardized digital timestamp format) and relative time formats. Agitation windows (±5 minutes) were labeled, and environmental features were normalized. Generalized linear mixed models were used to estimate agitation likelihood based on environmental fluctuations, controlling household-level clustering. Preliminary modeling revealed that elevated noise levels and abrupt light changes significantly increased agitation odds (p \u003C 0.05), especially bedroom and kitchen. Caregiver-targeted interventions in Phase III deployments demonstrated reduced agitation sensitivity to environmental volatility. This suggests that real-time contextual feedback enhanced caregiver responsiveness and behavior management. Momentary environmental context plays a critical role in dementia-related agitation. Time-series data offer a novel lens for understanding agitation triggers in dementia care. Findings support the development of context-aware, just-in-time interventions to empower caregivers and improve dementia care in home settings.  \nAbstract citation ID: igaf122.3625  \nMOMENTARY ENVIRONMENTAL CONTEXT AND  \nAGITATION IN PERSONS WITH DEMENTIA AT HOME  \nSETTINGS: A TIME-SERIES ANALYSIS  \nChunhong Xiao1, Azziza O.
