Results
During the intervention period, the covariate-adjusted proportion of vegetable-rich meal orders was 1.50 times higher than the control period.
Respondents who reported spending the least amount of money on eating out (used as a proxy measure for income) were the least likely to order vegetable-rich meals during the control period. However, these individuals increased the most their proportion of purchasing such meals during the intervention period.
