Background Recent case reports of scurvy indicate that vitamin C deficiency may be more prevalent that generally assumed. The Low Income Diet and Nutrition Survey (2003–05) of a representative sample of the low-income/materially deprived UK population included a plasma vitamin C measurement.
Methods Adults aged
19 years from all countries/regions of UK were screened to identify low-income/materially deprived households. A valid plasma vitamin C measurement was made in 433 men and 876 women. The results were weighted for sampling probability and non-response.
Results An estimated 25% of men and 16% of women in the low-income/materially deprived population had plasma vitamin C concentrations indicative of deficiency (<11 µmol l–1), and a further fifth of the population had levels in the depleted range (11–28 µmol l–1). Being a man, reporting low-dietary vitamin C intake, not taking vitamin supplements and smoking were predictors of plasma vitamin C levels
28 µmol l–1 in mutually adjusted logistic regression models.
Conclusion Health professionals need to be aware that poor vitamin C status is relatively common among adults living on a low income.
