Intervention effects on purchasing and consumption of fruits,
vegetables and beverages, adjusted for key covariates identified a
priori, are presented in Table 2. Details of the effectiveness of the
SHELf interventionwas reported in full elsewhere (Ball et al., 2015).
Briefly, compared to participants in the control group, participants
who received the price reduction intervention purchased more
vegetables (233 g/wk) during the three months of intervention
(T2), which was a 12% increase relative to the control group at time
2). Participants in the combined price reduction and skill-building
intervention, and in the price reduction intervention alone, also
purchased significantly more fruit (364 g/wk in the price reduction
arm or a 21% increase relative to the control group and 280 g/wk in
the combined arm or a 16% increase relative to the control group)
during the intervention than did participants in the control group
at T2. However, these increases were not maintained over the six
months post-intervention (T3). The skill-building intervention had
no significant effect on purchases of fruits or vegetables at T2 or T3
