High body mass index (BMI) is associated with severe COVID-19 but findings regarding the need of intensive care (IC) and mortality are mixed. Using electronic health records, we identified all patients in western Sweden hospitalised with COVID-19 to evaluate 30-day mortality or assignment to IC. Adjusted logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CI) for outcomes. Of totally 9761 patients, BMI was available in 7325 (75%), included in the study. There was a marked inverse association between BMI and age (underweight and normal weight patients were on average 78 and 75 years, whereas overweight and obese were 68 and 62 years). While older age, male sex and several comorbidities associated with higher mortality after multivariable adjustment, BMI did not. However, BMI ≥ 30 kg/m2 (OR 1.46, 95% CI 1.21–1.75) was associated with need of IC; this association was restricted to women (BMI ≥ 30; OR 1.96 (95% CI 1.41–2.73), and not significant in men; OR 1.22 (95% CI 0.97–1.54). In this comprehensive hospital population with COVID-19, BMI was not associated with 30-day mortality risk. Among the obese, women, but not men, had a higher risk of assignment to IC.
In addition to the consideration of individual medicine, social medicine focuses on the social references of health and sickness. In this context, it reflects the structures of the entire health care system, its functions and its functional deficits. It deals with the specific interaction between medicine and society and functions such as a link to the classical social sciences (1). Of particular interest in this context are the interfaces to sectoral health care provision. The working group "Nursing Care" of the Department "Practical Social Medicine and Rehabilitation" of the German Society for Social Medicine and Prevention examines the fundamental interfaces in our sectoral health care system from the perspective of social medicine in their current functions and perspectives, particularly in view of the future demographic challenges to be faced. Of particular importance is the interface between medicinal and nursing care in the areas of acute inpatient and homecare as well as in the area of geriatric care, including preventive measures. The aim of this article is to start a discussion on this subject.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
