  1. Data analysed using multiple regression. Data presented as means (SD), and unadjusted and adjusted differences in means (95% CI). aVariables were naturally logged transformed for analysis, and presented as geometric means (IQRs), and ratio of the geometric means (95% CIs). DEN group was fixed as the reference category in each model. bAdjusted for age, gender, SES (low, med & high), living status (living alone or not living alone), energy intake (kJ/d), survey year, smoking status (current smoker, past regular smoker & never smoked) and nutritional supplement use (yes/no).
