¹Number responding varied according to applicability of question. ²Scale and frequency variables were ranked into quartile categories for calculating Cohen’s kappa ³Ages reported in weeks up to 7, thereafter in whole months. ⁴A 10-point Likert scale on which 10 was “very willing” was used from willingness to try new foods. ⁵Could vary among 4 choices from “never” to “always”. All correlation measures significant at p ≤ 0.001.
