Outdoor activities and social support on anxiety in Chinese older adults: a cross-sectional study.

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
Objective: This study examined the associations between different types of outdoor activity and anxiety in older Chinese adults, and assessed whether social support was related to these associations as a potential mediator. Methods: Data were obtained from 8,813 adults aged 60 years and older who participated in the 2018 wave of the Chinese Longitudinal Healthy Longevity Survey. Outdoor activity was classified as Tai Chi, square dancing, neighborhood walking, other outdoor activities, and overall outdoor activity frequency. Anxiety symptoms were measured using the Generalized Anxiety Disorder-7 scale. Social support was assessed using a composite indicator covering family, caregiving, financial, and community-based support resources. Mediation analyses were conducted with 5,000 bootstrap resamples after adjustment for demographic, behavioral, residential, relational, and socioeconomic covariates. Results: Anxiety was identified in 11.57% of participants. Social support was consistently associated with lower anxiety scores. Overall outdoor activity, neighborhood walking, and other outdoor activities were associated with lower anxiety, and small indirect effects through social support were observed for these activity types. No significant mediation through social support was found for Tai Chi or square dancing. The observed correlations and regression coefficients were modest in magnitude. Conclusion: Routine outdoor activities, particularly neighborhood walking, were associated with lower anxiety levels in older adults, with social support accounting for part of these associations. Although the effect sizes were small and causal inferences cannot be drawn from the cross-sectional design, the findings suggest that accessible outdoor activities and supportive social environments may be relevant to healthy aging and later-life mental wellbeing.
