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.

Data are mean ± SE food and water only.

Data are percent ± SE.

⁴

Data are mean ± SE for total intake: food, water, antacids, and dietary supplements.
