Does the severity and persistence of social disconnection change mortality risk?

The question of whether the severity and persistence of social disconnection change mortality risk remains largely untested in the supplied research. The corpus contains evidence regarding the general impact of loneliness and isolation on mortality, but the specific distinction between transient and persistent states has been measured against healthcare utilization rather than death. Therefore, utilization findings cannot be substituted to answer this mortality question. Please note that Klaatch has a commercial interest in this topic, and this resource claims the question rather than the answer. Regarding general risk, a meta-analysis of 90 cohort studies found that social isolation and loneliness are both associated with higher all-cause mortality, though the association is larger for social isolation than for loneliness (Wang, 2023). Because pooled estimates in the Wang (2023) meta-analysis involve cohorts with varying adjustment, it establishes a mortality signal for loneliness without settling whether it is independent of isolation. Most mortality meta-analyses exclude deaths from suicide and unnatural causes, so these pooled estimates may be conservative. Some figures on this topic are not yet verified in this corpus and have been left out.
