Association of weight loss and weight fluctuation with mortality among Japanese American men
Article Abstract:
Weight loss and weight variation may be related to increased death rates in middle-aged men who smoke or have health problems, but not to death rates in healthy men. Researchers reviewed medical examinations of 6,537 Japanese American men and evaluated their mortality rates during an average follow-up period of 14.5 years. Men who tended to lose more than 4.5 kg had a high risk of dying from all causes except cancer. However, this connection between death and weight loss was weakened when other risk factors, such as disease and smoking, were adjusted for. Among men who were healthy and never smoked, there was no relation between weight change and mortality. Thus weight variation is more likely the result of other health problems than a cause of death to otherwise healthy people.

Serum total cholesterol and mortality: confounding factors and risk modification in Japanese-American men
Article Abstract:
The presence of certain risk factors appears to be associated with the higher death rates from cancer and other non-cardiac diseases seen among people with low total cholesterol (TC) levels. Researchers followed 7,049 Japanese-American men for 23 years. During that time, 1,954 men died. Approximately 39% died from cancer, 14% died from coronary artery disease and the rest died from stroke, obstructive lung disease, liver disease, trauma and other causes. The higher-than-expected number of deaths among the men with low TC was partially a result of preexisting disease and confounding factors such as smoking and untreated hypertension. Men with low TC levels had a higher risk of death from cancer and hemorrhagic stroke but a lower risk of death from coronary heart disease.

Effects of walking on mortality among nonsmoking retired men
Article Abstract:
Older men who walk more than one mile each day may gain important health benefits, including a lower mortality rate. Researchers examined 707 men aged 61-81 living in Hawaii. All the men were of Japanese descent, and they did not smoke. During the 12-year study, the mortality rate among men who walked more than one mile each day was 27.4% or lower, compared to 40.5% in men who walked less than a mile. Low-intensity exercise may be healthy in this age group, and more likely continued over many years than more intense activity.
