Objective: To evaluate the impact of a fruit and vegetable (F&V) subsidy program for disadvantaged Aboriginal children in Australia, implemented alongside the introduction of mandatory folic acid fortification of bread-making flour. Methods: A before-and-after evaluation was undertaken of a F&V subsidy program at three Aboriginal community-controlled health services in New South Wales. The program provided a weekly box of subsidised F&V linked to preventive health services and nutrition promotion for families. In this analysis, red blood cell (RBC) folate was assessed together with self-reported dietary intake at baseline and 12 months later in a cohort of 125 children (aged 0-17 years). Results: No children had low RBC folate at baseline or at follow-up; however, 33 children (26%) exceeded the reference range of RBC folate at baseline and 38 children (30%) exceeded the reference range at follow-up. Mean RBC folate levels increased substantially in children at follow-up (mean RBC folate z-score increased +0.55 (95%CI 0.36-0.74). Change in F&V intake (p=0.196) and mean bread intake (p=0.676) were not statistically significant predictors for change in RBC folate levels. Conclusions: RBC folate levels increased among these disadvantaged Aboriginal children following mandatory folic acid fortification and participation in a subsidised F&V program. Even before mandatory folic acid fortification, none of these children had low RBC folate. Implications: The effect on health of mandatory fortification of foods with folate is not clear, hence, ongoing population-based monitoring of folate levels to assess the impact of mandatory folic acid fortification is important. © 2014 The Authors.
