FV

INTRODUCTION: Studies have characterized food environments and documented its impact on access and consumption of healthy foods as well as diet-related health conditions. This study aims to characterize the local food environment in New York City's Washington Heights and Inwood community and to examine its influence on Hispanics' perceptions of healthy food access. METHODS: Person-level local food environments were created by spatially modeling food retailers selling fresh fruits and vegetables or low-fat products within a participant's 400- and 800-m residential radius buffers...

INTRODUCTION: A diet high in fruits and vegetables (FV) is associated with reduced risk of chronic disease. One strategy to incentivize FV consumption among low-income households is to make them more affordable through the Supplemental Nutrition Assistance Program (SNAP). This study aims to identify the cost effectiveness of subsidizing FV purchases among the one in seven Americans who participate in SNAP. METHODS: A cost-effectiveness analysis was conducted from a societal perspective to estimate lifetime costs and health gains associated with subsidizing FV purchases...

Hispanic families are at elevated risk for certain diet related illnesses including obesity and diabetes. Brighter Bites is a 16-week school-based program that delivers produce and nutrition education to high-need areas. The purpose of this study was to explore the adoption of Brighter Bites healthy eating strategies in low-income Spanish-speaking families as well as barriers to the sustainability of improved dietary behaviors using Photovoice. Two researchers worked with a predominately Hispanic, low-income public school to conduct the project...

Despite growing attention to the problem of obesogenic environments, there has not been a comprehensive review evaluating the food environment-diet relationship. This study aims to evaluate this relationship in the current literature, focusing specifically on the method of exposure assessment (GIS, survey, or store audit). This study also explores 5 dimensions of "food access" (availability, accessibility, affordability, accommodation, acceptability) using a conceptual definition proposed by Penchansky and Thomas (1981)...

Reliable and valid measures of local food environments are needed to more fully understand the relationship between these environments and health and identify potential intervention points to improve access to, and the availability of, healthy foods. These measures also inform policy making, including the zoning of food outlets and food labelling/information requirements. A literature review was undertaken using health, behavioural and social sciences, nutrition and public health databases and grey literature, to determine available information on the measurement of local food environments...

Studying the relation between the residential environment and health requires valid, reliable, and cost-effective methods to collect data on residential environments. This 2002 study compared the level of agreement between measures of the presence of neighborhood businesses drawn from 2 common sources of data used for research on the built environment and health: listings of businesses from commercial databases and direct observations of city blocks by raters. Kappa statistics were calculated for 6 types of businesses-drugstores, liquor stores, bars, convenience stores, restaurants, and grocers-located on 1,663 city blocks in Chicago, Illinois...

BACKGROUND: The impact of local availability of healthy foods on dietary intake and health has been established. Interventions to local environments are being evaluated for their efficacy and sustainability. PURPOSE: The aim of this paper is to provide an evaluation of a community-driven approach to transform neighborhood healthy food availability. METHODS: The information provided comes from minutes of monthly meetings of the partners, newsletters, media, and other store and project documentation...

Studies that explore associations between the local food environment and diet routinely use global regression models, which assume that relationships are invariant across space, yet such stationarity assumptions have been little tested. We used global and geographically weighted regression models to explore associations between the residential food environment and fruit and vegetable intake. Analyses were performed in 4 boroughs of London, United Kingdom, using data collected between April 2012 and July 2012 from 969 adults in the Olympic Regeneration in East London Study...

BACKGROUND: Disparities in the type and density of food retail outlets have been hypothesized as a possible cause of differential obesity rates across racial/ethnic and income groups. Several local studies have documented differences in business environments by sociodemographic neighbourhood characteristics, but no data specific for youth have been published. This study analyses the food environment surrounding all public middle and high schools in the USA. METHODS: Buffers were calculated with a radius of 400 and 800 m from the main entrance of public secondary schools in the USA (n=31,622), and business establishments within those buffers were identified using InfoUSA proprietary business listings...

BACKGROUND: Consuming enough fruits and vegetables and engaging in regular physical activity are believed to be two important components of several lifestyle modifications for people with hypertension. The purpose of this study was to measure the degree to which US adults with hypertension achieved recommended intakes of fruits and vegetables and engaged in recommended levels of physical activity in 2003 and 2007. METHODS: Using the Behavioral Risk Factor Surveillance System (BRFSS) data conducted in 2003 (N = 264,178) and 2007 (N = 430,082), we determined the changes in the prevalence of eating > or =5 servings of fruits and vegetables and of obtaining Healthy People 2010 recommended level of physical activity among adults with hypertension during the period...

BACKGROUND: The relationship between intake of fruits and vegetables (F/V) during young adulthood and coronary atherosclerosis later in life is unclear. METHODS AND RESULTS: We studied participants of the Coronary Artery Risk Development in Young Adults (CARDIA) study, a cohort of young, healthy black and white individuals at baseline (1985-1986). Intake of F/V at baseline was assessed using a semiquantitative interview administered diet history, and coronary artery calcium was measured at year 20 (2005-2006) using computed tomography...

BACKGROUND: dietary modification can potentially reduce dementia risk, but the importance of fruits and the amount of vegetables and fruits required for cognitive maintenance are uncertain. We examined whether the minimal daily requirement of vegetables and fruits recommended by the World Health Organization (WHO) would independently lower dementia risk. METHODS: in this population-based observational study, we examined the diet of 17,700 community-living dementia-free Chinese older adults who attended the Elderly Health Centres in Hong Kong at baseline and followed their cognitive status for 6 years...

The reinforcing value of food is an important determinant of food intake. Research has yet to examine the relative reinforcing value (RRV) of snack foods in young children with overweight and obesity (OW/OB). The current study compared the RRV of high-energy dense foods (cookies) to low-energy dense foods (fruits) between preschoolers with OW/OB and healthy weight (HW). RRV of cookies and fruits in preschoolers with OW/OB (n = 30; Mage  = 4.4 ± 0.84; 60% male) and HW (n = 30; Mage  = 4.5 ± 0.85; 70% male) was assessed with a developmentally-tailored computer program which used a progressive fixed ratio reward schedule...

Obesity is a significant public health issue, and is associated with poor diet. Evidence suggests that eating behavior is related to individual differences in executive functioning. Poor executive functioning is associated with poorer diet (few fruits and vegetables and high saturated fat) in normal weight samples; however, the relationship between these specific dietary behaviors and executive functioning have not been investigated in adults with obesity. The current study examined the association between executive functioning and intake of saturated fat, fruits, and vegetables in an overweight/obese sample using behavioral measures of executive function and dietary recall...

BACKGROUND: The Prevalence of obesity and overweight has been increasing in many countries. Many factors have been identified as contributing to obesity including the food environment, especially the access, availability and affordability of healthy foods in grocery stores and supermarkets. Several interventions have been carried out in retail grocery/supermarket settings as part of an effort to understand and influence consumption of healthful foods. The review's key outcome variable is sale/purchase of healthy foods as a result of the interventions...

BACKGROUND: The 'deprivation amplification' hypothesis suggests that residents of deprived neighbourhoods have universally poorer access to high-quality food environments, which in turn contributes to the development of spatial inequalities in diet and diet-related chronic disease. This paper presents results from a study that quantified access to grocery stores selling fresh fruit and vegetables in four environmental settings in Scotland, UK. METHODS: Spatial accessibility, as measured by network travel times, to 457 grocery stores located in 205 neighbourhoods in four environmental settings (island, rural, small town and urban) in Scotland was calculated using Geographical Information Systems...

Most food-environment research has focused narrowly on select stores and restaurants. There has been comparatively less attention to non-storefront food sources like farmers' markets (FMs), particularly in urban communities. The objective of the present study was to assess FMs' potential contribution to an urban food environment in terms of specific foods offered, and compare FM accessibility as well as produce variety, quality, and price to that of nearby stores. Investigators conducted a detailed cross-sectional assessment of all FMs in Bronx County, NY, and of the nearest store(s) selling produce within a half-mile walking distance (up to two stores per FM)...

Cardiovascular disease is the leading cause of premature mortality in the developed world, and hypertension is its most important risk factor. Controlling hypertension is a major focus of public health initiatives, and dietary approaches have historically focused on sodium. While the potential benefits of sodium-reduction strategies are debatable, one fact about which there is little debate is that the predominant sources of sodium in the diet are industrially processed foods. Processed foods also happen to be generally high in added sugars, the consumption of which might be more strongly and directly associated with hypertension and cardiometabolic risk...

Prevailing thinking about obesity and related diseases holds that quantifying calories should be a principal concern and target for intervention. Part of this thinking is that consumed calories - regardless of their sources - are equivalent; i.e. 'a calorie is a calorie'. The present commentary discusses various problems with the idea that 'a calorie is a calorie' and with a primarily quantitative focus on food calories. Instead, the authors argue for a greater qualitative focus on the sources of calories consumed (i...
