From: The community and consumer food environment and children’s diet: a systematic review
Author (Year) | Sample size (n) | Specific exposure reported | FF outcome | Results |
---|---|---|---|---|
Powell et al. [36] | 47,675 | FV and FF prices from Cost of Living Index | Daily FV consumption | - A dollar increase in the price of FF is statistically significantly associated with a reduction in frequent consumption of FV by 6.7 percentage points (p<0.001). |
- A dollar increase in the price of FV is estimated to decrease FV consumption by 6.3 percentage points (z = 2.05). | ||||
Khan et al. [29] | 11,700 | FF prices from the Cost of Living Index and food outlet density | FF consumption in the past 7 days | - Higher FF prices were associated with lower childhood FF consumption (beta = −0.527, p<0.05). - FF restaurant outlet densities were significantly associated with FF consumption patterns (beta = 0.025, p<0.05). |
Sturm & Datar [39] | 4896 | Price indices for meat, FV, dairy and FF calculated from Cost of Living Index | Consumption of FV, milk, soft drinks and FF in the past 7 days | - Lower real prices for FV predict higher intake frequency (a 1SD increase in the price index for FV is associated with a 0.82 times per week reduction in the frequency of consumption of FV), higher dairy prices predict lower milk consumption (a 1 SD increase in dairy prices predicts a reduction in milk consumption of two-thirds of a glass per week), and increased meat price predicts increased milk consumption. |
- The effects on FF and SSB are small and generally insignificant. | ||||
Edmonds et al. [22] | 90 | FV, 100% juice availability and shelf space in food stores and restaurants around home | FV (including fried potatoes), juice and consumption per day | Significant positive correlations were found between restaurant juice (r = 0.61, p < 0.05) and vegetable availability (r = 0.53, p = 0.10) and Boy Scouts’ reported consumption of juice and vegetables, - but no relationships were detected with grocery store availability. |
Longacre et al. [33] | 1,547 | Availability of FF outlets (onsite audit) | FF intake in past week | Adolescent who lived in towns with > = 5 FF outlets were about 30% more likely to eat FF compared to those in town with no FF outlets (RR = 1.29, 95% CI 1.10 - 1.51). |
Leung et al. [32] | 215 | “Food and retail” scale - Food outlet audit on random street segments within 0.25 mile of home | Total energy intake | Inverse relationship between prevalence of food and retail locations and total energy intake (for a one quartile increase, OR=0.84, 95% CI 0.74-0.96). |
