Risk Factors for Death Among Hospitalized Patients Aged 21–64 Years Diagnosed with COVID-19—New York City, March 13–April 9, 2020

Abstract

Background COVID-19 mortality studies have primarily focused on persons aged ≥ 65 years; less is known about decedents aged <65 years. Methods We conducted a case-control study among NYC residents aged 21–64 years hospitalized with COVID-19 diagnosed March 13–April 9, 2020, to determine risk factors for death. Case-patients (n=343) were hospitalized decedents with COVID-19 and control-patients (n=686) were discharged from hospitalization with COVID-19 and matched 2:1 to case-patients on age and residential neighborhood. Conditional logistic regression models were adjusted for patient sex, insurance status, and marital status. Matched adjusted odds ratios (aORs) were calculated for selected underlying conditions, combinations of conditions, and race/ethnic group. Results Median age of both case-patients and control-patients was 56 years (range: 23–64 years). Having ≥ 1 selected underlying condition increased odds of death 4.45-fold (95% CI: 2.33–8.49). Patients with diabetes; morbid obesity; heart, kidney, or lung disease; cancer; neurologic/neurodevelopmental conditions; mental health conditions; or HIV had significantly increased odds of death. Compared with having neither condition, having both diabetes and obesity or diabetes and heart disease was associated with approximately threefold odds of death. Five select underlying conditions were more prevalent among non-Hispanic Black control-patients than among control-patients of other races/ethnicities. Conclusions and Relevance Selected underlying conditions were risk factors for death, and most prevalent among racial/ethnic minorities. Social services; health care resources, including vaccination; and tailored public health messaging are important for COVID-19 prevention. Strengthening these strategies for racial/ethnic minority groups could minimize COVID-19 racial/ethnic disparities.

Cirrhosis is an independent predictor for COVID-19 mortality: A meta-analysis of confounding cofactors-controlled data

“…This is an interesting study. To our knowledge, some other studies reported cirrhosis was not significantly associated with the risk for COVID-19 mortality in the multivariable analysis [2] , [3] , [4] . This suggested that the association between cirrhosis and COVID-19 mortality remained to be conclusive.…”

Body mass index does not impact survival in COVID-19 patients requiring veno-venous extracorporeal membrane oxygenation

“…Although obesity has been identified as a risk factor for worse outcomes in COVID-19, 23 - 25 This study may add to an existing body of literature that supports the “obesity paradox” in critically ill patients. In some studies, obese patients have been shown to have equivocal, or even improved outcomes compared to non-obese patients, 26 , 27 whereas others have questioned the validity of this observation when appropriate statistical controls were implemented.…”

Significant association between anemia and higher risk for COVID-19 mortality: A meta-analysis of adjusted effect estimates

“…1 showed the flow chart of related literature search and selection process. A total of twenty-three articles with 573,928 COVID-19 patients were eligibly included in this quantitative meta-analysis [ [10] , [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] ]. The characteristics of the eligible studies are summarized in Table 1 .…”
