TY - JOUR T1 - DOes body mass index adequately convey a patient's mortality risk? AU - Heymsfield SB, Cefalu WT Y1 - 2013/01/02 N1 - 10.1001/jama.2012.185445 JO - JAMA SP - 87 EP - 88 VL - 309 IS - 1 N2 - A Metropolitan Life Insurance Company (MLIC) statistician revealed an association between longevity and body weight in 1942. Lifespan was longest when body weight was maintained at the same level as 25-year-old adults with similar height and frame size.1 The initial 1942 MLIC ideal body weight tables were later revised to desirable weight tables in 1959 and again in 1983 to height and weight tables. Obesity was considered present when a person's weight exceeded his or her desirable weight by 20%.
