What factors are associated with hemoglobin levels in healthy college men?
In healthy college men, hemoglobin levels are significantly associated with pulse rate, potentially due to emotional factors, but not with other socio-economic or physiologic factors.
Pulse rate may warrant attention when interpreting hemoglobin in young men; hypothesis-generating for emotional factors and requires prospective confirmation.
Abstract 1. The distribution of hemoglobins (obtained by the Sahli method on venous blood and by the O2 capacity method of Van Slyke) and the red blood cell counts of 153 to 259 college men, selected for participation in the Grant Study, are reported. 2. There is a statistically significant relationship between the hemoglobin and the pulse rate (those subjects having higher pulse rates tending to have higher hemoglobins). This relationship is apparently associated with emotional factors. 3. No significant relationship could be established between hemoglobin level and a variety of other factors, including socio-economic, dietary, physiologic, medical, body-build and others.

Clark W. Heath (1948) conducted a cross-sectional in Healthy (n=259). Pulse rate was evaluated on Hemoglobin level. Higher pulse rates were significantly associated with higher hemoglobin levels in healthy college men, with no significant relationship found for socio-economic, dietary, or medical factors.
