Overweight, obesity, and all-cause mortality [3]

摘要

Dr Flegal and colleagues reported a beneficial association between being overweight and survival in a large cohort of general population adults. One study 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 ) 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.
