TLDR
Improving physical access to supermarkets may be one strategy to deal with the obesity epidemic; improving economic access to healthy foods is another.Abstract:
Objectives. We examined whether physical proximity to supermarkets or supermarket price was more strongly associated with obesity risk.Methods. The Seattle Obesity Study (SOS) collected and geocoded data on home addresses and food shopping destinations for a representative sample of adult residents of King County, Washington. Supermarkets were stratified into 3 price levels based on average cost of the market basket. Sociodemographic and health data were obtained from a telephone survey. Modified Poisson regression was used to test the associations between obesity and supermarket variables.Results. Only 1 in 7 respondents reported shopping at the nearest supermarket. The risk of obesity was not associated with street network distances between home and the nearest supermarket or the supermarket that SOS participants reported as their primary food source. The type of supermarket, by price, was found to be inversely and significantly associated with obesity rates, even after adjusting for individual-level so...read more

TL;DR: The scientific goal is to elucidate obesity pathogenesis so as to better inform treatment, public policy, advocacy, and awareness of obesity in ways that ultimately diminish its public health and economic consequences.

TL;DR: With the exception of urban sprawl and land use mix in the US the results of the current review confirm that the available research does not allow robust identification of ways in which that physical environment influences adult weight status, even after taking into account methodological quality.

TL;DR: A brief synthesis of the food environment literature is conducted, a new definition and conceptual framework that includes external and personal domains and dimensions within the wider food environment construct is introduced, and a discussion on the implications for future research in LMICs is discussed.

Distance to Store, Food Prices, and Obesity in Urban Food Deserts

TL;DR: Placing supermarkets in food deserts to improve access may not be as important as simultaneously offering better prices for healthy foods relative to junk foods, actively marketing healthy foods, and enabling consumers to resist the influence of junk food marketing.
Measuring Socio-Economic Position in Dietary Research: Is Choice of Socio-Economic Indicator Important?
TL;DR: The food purchasing behaviours of socio-economically disadvantaged groups were least in accord with dietary guideline recommendations, and hence are more consistent with greater risk for the development of diet-related disease.

A Modified Poisson Regression Approach to Prospective Studies with Binary Data
TL;DR: Results from a limited simulation study indicate that this approach is very reliable even with total sample sizes as small as 100, and the method is illustrated with two data sets.

TL;DR: This economic framework provides an explanation for the observed links between socioeconomic variables and obesity when taste, dietary energy density, and diet costs are used as intervening variables.

Neighborhood Environments: Disparities in Access to Healthy Foods in the U.S.
TL;DR: Neighborhood disparities in access to food are of great concern because of their potential to influence dietary intake and obesity and additional research is needed to address various limitations of current studies, identify effective policy actions, and evaluate intervention strategies designed to promote more equitable access to healthy foods.

Neighborhood characteristics associated with the location of food stores and food service places
TL;DR: Without access to supermarkets, which offer a wide variety of foods at lower prices, poor and minority communities may not have equal access to the variety of healthy food choices available to nonminority and wealthy communities.

TL;DR: Findings suggest the local food environment is associated with residents' recommended diets, and black Americans' fruit and vegetable intake increased for each additional supermarket in the census tract.
