Plasma pyridoxal 5'-phosphate concentrations in obese and nonobese black women residing near Petersburg, VA.
The vitamin B-6 status of 15 obese and 15 nonobese black women aged 21-51 y who were not taking vitamin supplements was assessed by using plasma pyridoxal 5'-phosphate (PLP) measurements. Ages, heights, and ideal body weights of the two groups were similar as were reported energy, protein, and vitamin B-6 intakes obtained by using 24-h intake data collected on two nonconsecutive days separated by at least 1 wk. The reported vitamin B-6 intakes were 1.18 +/- 0.44 mg/d (means +/- SD). Plasma PLP levels in the obese and nonobese black women were similar; these levels were also similar to those observed previously for white obese and nonobese women having similar physical characteristics. All subjects had plasma PLP levels indicative of adequate status with one possible exception. Obesity did not affect the plasma PLP levels in these black women.
