HEALTH MANAGEMENT. Increases death risk in African-American women with obesity and waist size

According to a new study led by researchers from the Slone Epidemiology Center at the Boston University higher overweight and obesity in African-American women, will increase the risk of death. Cause of death in women, moreover, was a larger waist size with a higher risk the not obese. The relationship between body size and risk of death was strongest for deaths from cardiovascular disease.
The study, published in the New England Journal of medicine, Deborah Boggs, ScD, a researcher at the Slone led.
Researchers assessed the relationship of body mass index (BMI) and waist circumference risk of death over a period of 13 years of follow up in the black women's health study, an ongoing study of 59,000 African-American women in the United States. The Auditors focused on 33.916 women who had never smoked and were free from cardiovascular disease and cancer at the beginning of the study.
The risk of death was 18 percent, for every 5 units increase in BMI and BMI most from cardiovascular disease death was connected. The risk of death from cardiovascular disease was two times higher for obese women (BMI 25-29) and three times higher for obese women (BMI of 30 or higher) compared with women with a healthy weight (BMI below 25). The researchers also found that a larger waist size increased risk of death among women is associated with, who were not obese been classified; A waist size was over 35 inches a 55 percent higher risk of death.
Whereas BMI is one good estimate of the total body fat, waist size is a measure of the distribution of body fat, particularly abdominal fat. Previous research suggests that belly fat is more metabolically active, plays a role in the development of insulin resistance and can be especially harmful for the long-term health. In those who are not obese may be waist size a better indicator of risk for many health consequences.
Earlier results found that risk of death with higher BMI in the white population increased, but the limited data available on African-Americans out, pointed, increasing risk of death only at a very high level of BMI.
"Today's results show that increases the risk of death in black women with increasing BMI of 25 or more similar to the pattern in the white people", said Boggs, main author of the study. "Our results emphasize the importance for women of a healthy weight, and keep additional inches from the waist in order to reduce the risk of death."
