Social activity participation, sex, and healthy aging among community-dwelling frail older adults: A secondary data analysis.
Article in Journal of Korean gerontological nursing, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThis study aimed to identify the influencing factors of healthy aging (HA) among frail older adults based on the activity theory of aging. We examined the relationship between perceived health (PH) and HA, with social activity participation (SAP) as a mediator and sex as a moderator.
methodsSecondary data analysis was conducted using data from a national survey of 505 frail older adults in Korea, including measures of PH, SAP, and HA. Analysis utilized SPSS/WIN 29.0 and PROCESS Macro v.4.2 (Model 14).
resultsPH was positively correlated with SAP (r=.18, p<.001) and HA (r=.43, p<.001), while the relationship between SAP and HA was not significant (r=-.07, p=.107). PH showed a statistically significant indirect effect on HA through SAP (β=-0.05, BootCI [-0.12~-0.01]), indicating that PH influenced HA both directly and indirectly via SAP. Sex significantly moderated the association between SAP and HA (β=0.24, BootCI [0.08~0.40]), such that SAP was negatively associated with HA in men, whereas no significant association was observed in women. The moderated mediation index was small but significant (β=0.06, BootCI [0.004~0.15]).
conclusionPH and SAP were significant determinants of HA among frail older adults, with the mediating role of SAP differing by sex. Although activity theory posits that social engagement promotes HA, these findings suggest that sex-specific patterns and individual preferences in social activities should be considered when designing interventions to support HA.
