The health benefits of social support have been widely documented. However, the social distancing practices from the COVID-19 pandemic is causing social disruption on a grand scale, potentially causing poor health outcomes. Through Google Trends analysis, we found a COVID-19-related surge in interest surrounding “loneliness.” We assessed if social isolation and loneliness increase the risk for all-cause and cardiovascular disease (CVD) mortality (ICD-10: I00–I99) and used the data to create a conceptual framework. Using the 10-year overall and cardiovascular mortality follow-up data (n = 12,019) from the National Health and Nutrition Examination Survey (1999–2008), we conducted survival analyses and found that individuals who experience social isolation or loneliness have a significantly higher likelihood of overall and CVD mortality than those without support. These effects generally remained strong with further adjustment for NHANES-detected health and demographic differences showing the need to address COVID-19 related loneliness through increasing social nearing.
