27. Skinner et al. (A-16) conducted a cross-sectional telephone survey to obtain 24-hour dietary recall of
infants’ and toddlers’ food intakes, as reported by mothers or other primary caregivers. One finding
of interest was that among 561 toddlers ages 15–24 months, the age in weeks of the child was
negatively related to vitamin C density b^1 ¼ :43, p ¼ :01. When predicting calcium density, age in
weeks of the child produced a slope coefficient of 1:47 with a p of .09.
