      Abstract: Mortality in relation to relative   weight and exercise was analyzed from data collected in the first   2 years of the American Cancer Society's Cancer Prevention Study   II. It included data on 868,620 persons who had no history of   cancer, heart disease, or stroke and who were not sick at the   start of the study. Standardized mortality ratios (SMR) were 187   for men who were 20% or more underweight and 187 for men who were   40% or more overweight. Comparable SMR in women were 186 and 178.   Current smokers had considerably higher SMR than nonsmokers for   all causes of death and cancer deaths at each relative weight   category. Degree of exercise reported by subjects was inversely   related to mortality, independent of smoking habits. Subjects who   exercised heavily and died of cancer of the lung, colon-rectum,   and pancreas had 20% to 37% higher SMR than men and women who   reported moderate exercise.
