To the Editor: In their study of midlife body mass index, Dr Yan and colleagues1 found that obesity in middle-aged persons with or without cardiovascular risk factors predicted a high risk of hospitalization and mortality from coronary heart disease, cardiovascular disease, and diabetes beginning at age 65 years. However, they did not address whether this was also a risk factor for total mortality. That analysis would be valuable to more fully understand the importance of obesity for long-term health.
