Abbreviations: BMI, body mass index; FAVVA, Fruit and Vegetable Variety index. * p < 0.05; linear regression modelling with adjustment for the area of residence, ability to manage on their current income, total energy intake and baseline FAVVA. Note: Women with ‘Underweight’ BMI were excluded from the analysis due to the small sample size.
