n = 8881. Unless otherwise indicated, values are means ± SEs. The estimates presented were obtained using analytic sample 3, and include individuals aged ≥19 y that were not pregnant or lactating with complete information for the DSMQ and at least one 24HR. DFE, dietary folate equivalents.
Significant difference in estimated prevalence of any DS or MVM use when compared with the estimated prevalence of any DS or MVM use, respectively, of the referent group (i.e., DSMQ only). A Bonferroni-corrected P value < 0.0167 was considered statistically significant. DFE, dietary folate equivalents; DS, dietary supplement; DSMQ, Dietary Supplement and Prescription Medication Questionnaire; MVM, multivitamin-mineral; 24HR, 24-h dietary recall.
MVMs are categorized as DSs containing ≥3 vitamins and ≥1 mineral.
