Serum inorganic phosphate in middle-aged men. I. Inverse relation to body weight.

Serum inorganic phosphate was determined in 752 men born in 1926. An inverse correlation was found between serum inorganic phosphate levels and body weight. Other parameters of possible relevance to this finding, such as serum calcium, serum albumin, serum lambda-glutamyltransferase, and the occurrence of upper gastrointestinal disorders were analysed, and no correlations to the phosphate level were detected.
