Body-Mass Index, Waist-to-Height Ratio and More... Waist is usually measured at one inch above the navel. Body-Mass Index (BMI) The body-mass index (BMI) is calculated by dividing your weight (in kg) by the square of your height (in meters). A BMI greater than 25 may indicate that you are overweight, while a BMI greater than 30 generally indicates obesity. A BMI of 27.8 for men and 27.3 for women is the cutoff point for obesity used in the National Health and Nutrition Examination Survey (NHANES II).
(Department of Health and Human Services Consensus Conference on Obesity, April,1 1992) Dr. A BMI from 20 through 26: desirable for most middle-aged adults. A BMI from 27 through 29: moderately overweight, carries a slightly increased risk of weight-related health problems, such as high blood pressure, high blood cholesterol, heart disease and adult-onset diabetes. A BMI of 30 through 40: truly overweight, the risk of developing heart disease and other weight-related conditions rises sharply.

Results from a new study in laboratory mice show that nighttime exposure to artificial light stimulated the growth of human breast tumors by suppressing the levels of a key hormone called melatonin. The study also showed that extended periods of nighttime darkness greatly slowed the growth of these tumors. The study results might explain why female night shift workers have a higher rate of breast cancer.
It also offers a promising new explanation for the epidemic rise in breast cancer incidence in industrialized countries like the United States. The National Cancer Institute and the National Institute of Environmental Health Sciences, agencies of the federal National Institutes of Health, provided funding to researchers at the Bassett Research Institute of the Mary Imogene Bassett Hospital in Cooperstown, New York and The Thomas Jefferson University in Philadelphia, Pa. To test this hypothesis, the researchers injected human breast cancer cells into laboratory mice. Source : NIH.
