About The Study: In this cross-sectional study, social isolation was found to have increased globally after the COVID-19 pandemic, with the initial increase disproportionately seen in lower-income populations and subsequent increases broadening across socioeconomic strata. Targeted interventions for vulnerable groups and research examining country-level policies are urgently needed to mitigate high isolation levels and reduce inequities.
