Abstract

There has been insufficient data available for suggesting a recommended dietary allowance for pantothenic acid in the elderly population. The purpose of this study was to determine the average dietary intake of pantothenic acid and correlate it with urinary excretions and the blood levels of this vitamin to assess the pantothenic acid status of the elderly population.

A seven day diet record was obtained from 65 non-institutionalized and 26 institutionalized persons over 65 years of age assessed to be free of chronic diseases. A 24 hour urine specimen and a fasting blood sample was obtained from each study participant. An average of the seven day diet record was calculated to obtain the amount of pantothenic acid consumed per day. The averaged value calculated for dietary in-take was correlated with urinary excretion and blood levels of the vitamin. The amount of pantothenic acid ingested from vitamin supplements was also calculated. The total amount of pantothenic acid (dietary and vitamin sources) was correlated with urinary excretion levels and blood levels of the vitamin.

The average dietary intake of pantothenic acid for the elderly population studied was 5.9 ± 1.4 mg/day. The average total intake of pantothenic acid (dietary and vitamin sources) was 10.3 ± 13.8 mg/day. The dietary intake of pantothenic acid ranged from 2.5 - 9.5 mg/day and the intake of pantothenic acid from vitamin plus dietary sources ranged from 2.5 - 122.4 mg/day. there was a low to moderate correlation between the intake of pantothenic acid and the urinary excretion of the vitamin and a low to moderate correlation between the intake levels and blood levels of pantothenic acid.
