Life-Space Mobility Is Related to Loneliness Among Living-Alone Older Adults: Longitudinal Analysis With Motion Sensor Data.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLife-space mobility can be a behavioral indicator of loneliness. This study examined the association between life-space mobility measured with motion sensors and weekly vs. annually reported loneliness.
methodsParticipants were older adults who lived alone. Passive infrared motion sensors were placed in the bathroom, bedroom, kitchen, and living room. Time spent in each room and out-of-home across the day was derived and used as the measure of life-space mobility. Participants reported via weekly questionnaires whether they felt lonely. In annual visits, the UCLA loneliness scale was administered to a subsample (n = 71), and the scores were categorized into high, moderate, and low groups. We used generalized estimating equations (GEE) to correlate life-space mobility with weekly and yearly loneliness. Repeated observations from each individual were bootstrapped for 1000 rounds to associate annual and weekly loneliness measures.
resultsWe analyzed 4995 weeks of data from 139 participants (age = 78.1 ± 8.6, 74% female, 23% African Americans, 14% with MCI diagnosis). An additional hour in the bedroom in the afternoon was associated with a 21.4% increased odds (OR = 1.214, p = 0.049) of experiencing loneliness in the week. An additional hour out-of-home in the morning and in the afternoon was associated with 18.2% (OR = 0.818, p = 0.040) and 15.3% (OR = 0.847, p = 0.018) fewer odds of experiencing weekly loneliness. In the subsample with annual loneliness assessments, an additional hour out-of-home was associated with 38.1% (OR = 0.619, p = 0.006) fewer odds of being in the high UCLA loneliness group. Compared with the low UCLA group, those with high UCLA scores were five times more likely to report loneliness weekly (OR = 5.260, p = 0.0004).
conclusionsFrequent and objective measurements of mobility combined with self-reported social wellbeing information can offer new insights into the experience of loneliness and provide opportunities for timely interventions.
