†Data not available for 2004. Results were derived from logistic regression analyses using the SURVEY module and user-defined simplest models are reported: only variables with P < 0·05 were retained and reported, except for ‘survey year’ which was forced into the final model. The full model included demographics (sex, age group, education, income, employment status, country of birth) and associated dietary behaviours (food shopping and preparation responsibility, purchase of meals away from home on day prior to the survey).
