Abstract This study explores the association between neighborhood social and economic change from 2009 to 2013 and changes in the retail food environment from 2013 to 2017 in Madrid (Spain). We classified neighborhoods into four types: decreasing SES, new housing/gentrifying, increasing SES, and aging (population and housing). Food store data was obtained from a retail spaces census and classified as supermarket, specialized small store, or fruit and vegetable store. Compared to aging areas, new...

Abstract Background Exposure to Bisphenol A (BPA) is ubiquitous and includes dietary and environmental pathways. BPA is rapidly glucuronidated in the body, and both BPA and its conjugates can be readily measured in urine. Objectives To investigate the contribution of canned food and beverages, known sources of BPA contamination, to BPA biomarkers of exposure using dietary and urinary BPA concentration information in a representative sample of the U.S. population. Methods We evaluated 7669 NHANES...

Abstract Places where we buy food influence dietary patterns, making local food environments a good example of a mass influence on population diets. Cross-cultural studies, using reliable methods, may help understanding the relationship between food environments and diet-related health outcomes. We aimed to understand cross-national differences in the local food environment between Madrid and Baltimore by comparing an average neighborhood in each city in terms of food store types, healthy food a...

Many endocrine-disrupting chemicals (EDCs), including bisphenol A (BPA), are approved for use in food packaging, with unbound BPA migrating into the foods it contacts. Children, with their developing organ systems, are especially susceptible to hormone disruption, prompting this research to model the potential dose of BPA from school-provided meals. Probabilistic exposure models for school meals were informed by mixed methods. Exposure scenarios were based on United States school nutrition guide...

Half of the seafood consumed globally now comes from aquaculture, or farmed seafood. Aquaculture therefore plays an increasingly important role in the global food system, the environment, and human health. Traditionally, aquaculture feed has contained high levels of wild fish, which is unsustainable for ocean ecosystems as demand grows. The aquaculture industry is shifting to crop-based feed ingredients, such as soy, to replace wild fish as a feed source and allow for continued industry growth. ...

There is a substantial need among clinicians for health-related, evidence-based recommendations. Evidence-based recommendations help distill research findings and aid health care providers in making clinical decisions. However, it is infeasible for providers to sort through thousands of available guidelines, and heterogeneity among recommendation developers (e.g., composition, processes, outputs) can make it difficult for clinicians to identify which recommendations are trustworthy, feasible, an...

A pilot multiphase environmental intervention (February to September 2011) was conducted in 4 intervention and 4 comparison carry-outs in low-income urban areas of Baltimore, Maryland, to examine the association between exposure to a point-of-purchase intervention and purchasing behavior among customers (n = 186). Intervention exposure score (IES; range: 0–24) combined the number of intervention materials seen. Multivariate linear regression calculated an adjusted beta-coefficient (β) and 95% co...

The US food system functions within a complex nexus of social, political, economic, cultural, and ecological factors. Among them are many dynamic pressures such as population growth, urbanization, socioeconomic inequities, climate disruption, and the increasing demand for resourceintensive foods that place immense strains on public health and the environment. This review focuses on the role that policy plays in defining the food system, particularly with regard to agriculture. It further examine...

Youth obesity has increased over the past two decades in South Korea. Researchers employed in-depth interviews and focus-group discussions with parents and teachers from 26 schools in metropolitan South Korea, to examine environmental factors affecting youth eating habits. Home environment and exposure to healthy foods were the most important factors influencing healthy eating habits. Families with working mothers eat out more than do families with stay-at-home mothers. Poor nutrition education ...
