Mortality Rate - Obese Patients
The majority of studies show an increase in mortality rate associated with obesity (body mass index > 30).
Obese individuals have a 50-100 percent increased risk of death from all causes, compared with normal-weight individuals (body mass index 2025). Most of the increased risk is due to cardiovascular causes.
Life Expectancy and Obesity
Life expectancy of a moderately obese person could be shortened by 2 to 5 years.
White men between 20 and 30 years old with a body mass index > 45 could shorten their life expectancy by 13 years.
White women in the same category could lose up to 8 years of life.
Young African American men with a body mass index > 45 could lose up to 20 years of life; African American women, up to 5.
Obesity Mortality Risk Study
A study of more than 1 million adults in the United States (457,785 men and 588,369 women), investigated the relation between body mass index and the risk of death from all causes, cancer, and cardiovascular disease. In people who had never smoked, the lowest point of the mortality curve occurred at a body mass index of 23.5 to 24.9 in men and 22.0 to 23.4 in women. Above those points, the relative risk of death increased linearly with increased body mass indices in both men and women.
