  1. The local food environment and its association with the dietary quality of mothers Christina Black NIHR Doctoral Research Fellow MRC Lifecourse Epidemiology Unit 12th June 2014

  2. Black et al, Health & Place 2014 Caspiet al, Health & Place 2012

  3. Methodological limitations Food outlets Home/ frequently visited locations • Few studies have: • Linked activity space exposures to dietary outcomes • Measured the full range of food outlets • Assessed the moderating role of level of education Perchouxet al, Health & Place 2013 Zenk et al, Health & Place 2011

  4. Food environment score creation Thornton and Kavanagh, Nutrition & Diabetes 2012

  5. Example: Healthy FES (8.8 x n )+(6.3 x n ) = Less healthy FES Healthy FES Overall FES - = Less healthy FES (1.1 x n )+(8.3 x n ) =

  6. Crozier et al, European Journal of Clinical Nutrition 2010

  7. Mothers’ characteristics by education a Pearson correlation

  8. Environmental factors by education a Spearman correlation

  9. Overall FES & diet by education Interaction (FES & education): Low & mid p=0.16 Low & high p=0.04

  10. Results: Regression: mother’s diet score & food environment scores

  11. Summary and implications • The direction of relationships between food outlet accessibility and dietary quality differ by education level • Less healthy food outlets are more prevalent than healthier food outlets • Mothers’ with higher education levels may be less susceptible to poorer food outlet exposures than mothers with low education. • Further research testing educational moderation effects is needed • Local authorities could improve the imbalance through planning restrictions, particularly in more deprived areas
