To the Editor: Dr Flegal and colleagues1 reported a beneficial association between being overweight and survival in a large cohort of general population adults. One study2 found a 20% and 30% improvement in 30-day and 1-year survival, respectively, among both overweight and obese patients admitted to an intensive care unit. Other studies (see citations in 2) reported better survival (the obesity paradox) among obese patients with chronic diseases such as heart failure, chronic kidney disease, and human immunodeficiency virus/AIDS compared with normal weight patients.
