Background: Longitudinal studies of Total Body Potassium (TBK) are rare. Assessing TBK in order to evaluate Body Cell Mass (BMC) is important in the measure of Body Composition and aging. Objectives: The aim of this study was to assess TBK and BCM in healthy men longitudinally in order to evaluate the changes with age. Design: Longitudinal study Subjects: Body composition of 133 healthy Italian men, 20 to 66 years of age, was measured by whole-body counting of 40K. BCM (kg) was calculated as 0.00833 × TBK (mmol). Results: There was a significant increase in overweight and obese subjects between entry into and exit from the study. There was no significant decrease in TBK in this sample. The maximum BCM score from early age (30 years of age) was found to be a significant predictor of BMI after age 30. Conclusion: Subjects with high maximum BCM at early age tend to increase in BMI as they age.
Studi longitudinali di misura del potassio 40 sono rari. Effettuare tale misura è tuttavia importante nella valutazione dei cambiamenti della composizione corporea con l’età. Lo scopo del lavoro è stato quello di misurare longitudinalmente il potassio 40 e la massa cellulare metabolicamente attiva in maschi. E’ stata effettuate la misura del potassio 40, attraverso un contatore di potassio, ogni anno in 133 maschi di età compresa tra i 20 ed i 66 anni. La massa cellulare metabolicamente attiva (BCM) è stata calcolata con la seguente formula: 0.00833 × TBK (mmol). I risultati mostrano un significativo aumento di soggetti soprappeso ed obesi tra l’ingresso e l’uscita dallo studio. Non c’è stata alcun significativa diminuzione del potassio in questo campione di popolazione. Il picco massimo di BCM è stato riscontrato al di sotto dei 30 anni di età ed era significativo del BMI dopo i 30 anni di età. In conclusione i soggetti con una elevata BCM in età giovanile tendevano ad aumentare il BMI con il passare degli anni.

The maximum BCM score from early age (30 years of age) was found to be a significant predictor of BMI after age 30.
