Longevity, mortality and body weight

[Guest guest]

Hi All, Study says longevity correlates with body weight. Is it calories

or weight or both? I like weight. It is accurate. It is valuable to know,

I think.

I liked:

" Findings show absolute body size is negatively related to longevity and

life expectancy and positively to mortality. Trend lines show an average age

at death versus weight slope of -0.4years/kg. We also found that gender

differences in longevity may be due to differences in body size "

The purpose of this study was to analyze the relation of total body weight to

longevity and mortality. The MEDLINE database was searched for data that allow

analysis of the relationship between absolute body weight and longevity or

mortality. Additional data were used involving US veterans and baseball players.

Trend lines of age at death versus body weight are presented. Findings show

absolute body size is negatively related to longevity and life expectancy and

positively to mortality. Trend lines show an average age at death versus weight

slope of -0.4years/kg. We also found that gender differences in longevity may be

due to differences in body size. Animal research is consistent with the findings

presented. Biological mechanisms are also presented to explain why increased

body mass may reduce longevity. Life expectancy has increased dramatically

through improved public health measures and medical care and reduced

malnutrition. However, overnourishment and increased body size have promoted an

epidemic of chronic disease and reduced our potential longevity. In addition,

both excess lean body mass and fat mass may promote chronic disease.
