    Serum Ascorbic Acid and Gallbladder Disease Prevalence Among US Adults: The Third National Health and Nutrition Examination Survey (NHANES III)

    Simon JA, Hudes ES

    Published in Archives of Internal Medicine

    Methodology

    Cross-sectional analysis of NHANES III data on serum ascorbic acid and gallbladder disease prevalence in a nationally representative US adult sample

    Key Findings

    Higher serum vitamin C levels were inversely associated with gallbladder disease prevalence, particularly in women, with a dose-response gradient across quintiles

    Conclusions

    Serum ascorbic acid is inversely and independently associated with gallbladder disease prevalence

    Limitations

    Cross-sectional design precludes causal inference; single serum measurement; residual confounding

    Supplements Studied

    Vitamin C
    Vitamin

    To examine the relationship of ascorbic acid, an antioxidant nutrient involved in cholesterol catabolism, to gallbladder disease, we analyzed data collected from a probability sample of US adults.
