Table 4 Food Purchasing and Fruit and Vegetable Consumption by Time and Intervention Status

From: Substantial improvements not seen in health behaviors following corner store conversions in two Latino food swamps

  Intervention Comparison Mean Difference (Follow-up – Baseline)
Mean (SD) Mean (SD)
  Baseline Follow-up Baseline Follow-up Intervention Comparison
  (N = 313) (N = 323) (N = 482) (N = 568)   
Dollars spent on food per weeka 131.6 (64.0) 140.6 (126.0) 123.1 (66.4) 134.8 (74.8)** 9.0 11.7
Dollars spent on fruits and vegetables per weeka 46.2 (28.4) 49.8 (33.9) 44.6 (29.7) 47.2 (32.6) 3.6 2.6
Percent of dollars spent on fruits and vegetables 36.5 (16.7) 38.1 (17.6) 37.7 (18.0) 36.9 (18.7) 1.6 −0.8
Servings of fruits and vegetables consumed each day 4.4 (2.0) 4.2 (2.1) 4.5 (2.4) 4.8 (2.3) −0.2 0.3
  1. NOTES: Significant differences in continuous variables were tested between intervention baseline and follow-up using independent sample t-tests, comparison baseline and follow-up using independent sample t-tests tests, and mean difference (follow-up – baseline) for intervention and comparison using a F-test on the interaction term of a linear regression (more details can be seen in Additional file 3: Table S3)
  2. **p < 0.01
  3. aThe significance of the mean difference was not tested, as this variable was only of interest to calculate percent of dollars spent on fruits and vegetables
