Web-Based Light, Activity, and Sleep Program to Improve Quality of Life in Adults 70 and Older

What this Trial Is About

Researchers are evaluating a behavioural intervention called Light, activity and sleep in my daily life LAS aimed at improving quality of life for community-dwelling older adults aged 70 and over. The study focuses on addressing challenges related to circadian rhythm sleep disorders, poor sleep, reduced physical activity, and time spent indoors, which affect wellbeing in this population. The intervention targets light-related behaviour, outdoor walking, and sleep routines to promote active ageing and independence. The LAS intervention is delivered as a 9-week web-based course with nine modules covering electric lighting, daylight, outdoor physical activity, and sleep. Participants also receive a test kit with items like light bulbs, a sleep mask, and a sleep diary to support engagement and experimentation. The course includes one introductory physical meeting and three additional meetings held at a senior citizen meeting point. All participants receive the same noninvasive behavioural education and support. Participants complete questionnaires, interviews, and wear accelerometers to track activity and rest patterns before and after the course, with follow-ups at 3, 6, and 10 months after baseline. Outcomes measured include usability of the intervention, mood, sleep quality, behavioural skills, quality of life, physical activity, sedentary behaviour, and step counts. The study also explores factors that help or hinder daytime outdoor walking. Results will guide improvements for future delivery within municipal health promotion services.
