Physical activity and fitness levels did not significantly correlate with serum ascorbate in males. However, in females, higher physical fitness and younger age were linked to increased serum ascorbate levels.

Area of Science:

  • Nutritional biochemistry
  • Public health research
  • Human physiology

Background:

  • Serum ascorbate (Vitamin C) is a vital antioxidant.
  • Understanding factors influencing serum ascorbate levels is crucial for public health.
  • Previous research has explored diet and lifestyle factors, but population-level data on physical activity and fitness is less common.

Purpose of the Study:

  • To investigate the association between physical activity, physical fitness, and serum ascorbate levels.
  • To examine these relationships within the adult population of Northern Ireland.

Main Methods:

  • Cross-sectional population study of 1600 individuals in Northern Ireland.
  • Physical activity assessed via computer-assisted interviews.
  • Physical fitness estimated using maximal oxygen uptake (VO2 max) extrapolation.

  • Serum ascorbate measured using a colorimetric assay.

    • Main Results:

    • Mean serum ascorbate was higher in females than males (p < 0.001).
    • Smokers had lower serum ascorbate than non-smokers in both sexes (males p = 0.01, females p < 0.001).
    • In males, no significant relationship was found between serum ascorbate and age, social class, BMI, physical activity, or fitness. In females, serum ascorbate was associated with age (p < 0.01) and physical fitness (p < 0.05).

    Conclusions:

    • Serum ascorbate levels are influenced by sex and smoking status in the Northern Ireland population.
    • Physical fitness and age are significant factors for serum ascorbate in females, but not in males.
    • Further research could explore the mechanisms behind sex-specific associations.
