Summary
This summary is machine-generated.A new supermarket improved fruit and vegetable intake for children in public housing, but only if their families lacked vehicle access. This highlights how mobility barriers impact neighborhood food environment benefits.
Area Of Science
- Public Health
- Nutrition Science
- Community Health
Background
- Food deserts disproportionately affect low-income, minority communities.
- Access to supermarkets can influence dietary patterns.
- Transportation barriers can limit food choices.
Purpose Of The Study
- To evaluate the impact of a new supermarket on children's dietary patterns in a public housing community.
- To examine how proximity to a supermarket affects fruit and vegetable consumption.
- To explore the role of transportation barriers in moderating these effects.
Main Methods
- Utilized data from the Watts Neighborhood Health Study (WNHS) in South Los Angeles.
- Surveyed children (9-17 years) and a household adult before and after supermarket opening.
- Employed ANCOVA linear regression models to analyze dietary outcomes and proximity, considering transportation barriers.
Main Results
- Living near the new supermarket did not significantly improve overall dietary patterns.
- Children without vehicle access showed increased fruit and vegetable consumption when living closer to the supermarket.
- Dietary improvements were contingent on overcoming transportation barriers.
Conclusions
- Supermarket proximity alone is insufficient to improve diets; mobility is a key factor.
- Neighborhood food environment impacts are modified by individual transportation access.
- Comprehensive interventions addressing both food access and mobility are necessary for vulnerable populations.

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children...
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?
