UKHLS: dietary data collection

While there were no FFQs or diet diaries collected, there are a number of diet-related questions (see the table below). From Wave 7, some of these questions were based on the Eating Choice Index which has been shown in the NSHD to discriminate unhealthy and healthy eating [50].

The COVID-19 surveys contained specific questions about food insecurity which are outlined in the second table below.

In addition to the questions in the first table, mothers answered information about their child’s breastfeeding, including the age of their child when they stopped breastfeeding.
