Superscripts denote sets of within-gender age groupings with prevalence estimates that are statistically indistinguishable from the lowest (a) or highest (b) population mean, as determined by Hsu's procedure (22) with α = 0.025. * The relative SE is >30%; this estimate is unreliable.
2
Data are mean ± SE foods only.
3
Data are percent ± SE.
4
Data are mean ± SE for total intake: foods and dietary supplements.
