  1. 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.
