Context: At least 40% of cancers are linked to environmental or behavioral factors, and dietary behavior appears to be a major lever. Epidaure Market is a prevention initiative developed using a method for co-constructing health promotion initiatives and prevention programs that stratifies evidence from the scientific literature and combines it with experiential knowledge (DEVA, TPB, BCT). It promotes a sustainable diet (i.

Objectives: Consideration of future consequences (CFC) distinguishes individuals who adopt behaviours based on immediate needs and concerns from individuals who consider the future consequences of their behaviours. We aimed to assess the association between CFC and diet, and testing the mediating role of food choice motives on this relationship.

Design: Individuals (aged ≥ 18 years) completed the CFC-12 questionnaire in 2014, at least three 24-h dietary records, and a food choice motive questionnaire.

Objective: To explore store-specific grocery shopping patterns and assess associations with the objective and perceived retail food environment (RFE).

Design: This cross-sectional study used principal component analysis and hierarchical cluster analysis to identify grocery shopping patterns and logistic regression models to assess their associations with the RFE, while adjusting for household characteristics.

Setting: The Montpellier Metropolitan Area, France.

Background: Reducing meat consumption is advocated for healthier and more sustainable diets. However, behavioral studies are needed to better understand the mechanisms underlying meat-reducing dietary changes.

Objectives: The main aim of this study was to compare the motives associated with stages of change toward meat reduction in French adults, using the transtheoretical model (TTM).

Purpose: As the French West Indies are facing an ongoing nutrition transition with increasing type-2 diabetes mellitus (T2DM) prevalence, our study aimed to evaluate the effect of potential shifts in dietary patterns on T2DM risk in French West Indian adults according to several scenarios.

Methods: We used a cross-sectional multistage sampling survey on dietary intake conducted in 2013 on a representative sample of Guadeloupeans and Martinicans adults (n = 1063). From previously identified current dietary patterns, we used PRIME-Diabetes, a comparative risk assessment model, to estimate the effect of potential shifts from the "transitioning" pattern to the "convenient," the "prudent," and the "traditional" ones on T2DM risks.

Background: Mechanisms underlying the associations between changes in the urban environment and changes in health-related outcomes are complex and their study requires specific approaches. We describe the protocol of the interdisciplinary UrbASanté study, which aims to explore how urban interventions can modify environmental exposures (built, social, and food environments; air quality; noise), health-related behaviors, and self-reported health using a natural experiment approach.

Methods: The study is based on a natural experiment design using a before/after protocol with a control group to assess changes in environmental exposures, health-risk behaviors, and self-reported health outcomes of a resident adult population before and after the implementation of a time series of urban interventions in four contiguous neighborhoods in Paris (France).

Environmental features such as the 'foodscape' defined as the physical, sociocultural and economic space in which people encounter meals and foods, might be associated with dietary intake and health outcomes. This review focuses mainly on the spatial approach of the foodscape, i.e.

Article Synopsis
  • A cross-sectional study aimed to identify the motivations behind non-vegetarians reducing meat consumption and increasing legume intake in a large cohort of 25,393 French participants, mostly women around 55 years old.
  • The study focused on various change-inducing motives such as health, taste, and environmental concerns, finding that health and nutrition were the strongest drivers for reducing meat while taste preferences influenced legume consumption.
  • Results indicated a correlation between specific motives and individual characteristics, revealing that people motivated by health and nutrition were more likely to change their eating habits.

Background: The Healthy Purchase Index (HPI) assesses the nutritional quality of food purchases (FP) from food group expenditure shares only. However, it was developed from the FP of a disadvantaged population.

Objective: To adapt and validate the HPI for a general population.

Purpose: The purpose of this study was to assess whether the retail food environment, measured by multiple indicators around the home and in activity space, was associated with the nutritional quality of food purchases.

Methods: This cross-sectional study included 462 households from a quota sampling survey conducted in the south of France (Montpellier Metropolitan Area). The revised Healthy Purchase Index was implemented in order to assess the nutritional quality of food purchases.

Background: To limit the spread of COVID-19, a strict lockdown was imposed in France between March and May 2020. Mobility limitations and closure of non-essential public places (restaurants, open-air markets, etc.) affected peoples' food environment (FE) and thus their food purchasing practices (FPPs).

Objective: The Caribbean has seen a dramatic shift in the obesity and chronic disease prevalence over the past decades, suggesting a nutrition transition. Simultaneously, Martinique has faced a demographic transition marked by significant population ageing. We aimed to differentiate the contribution of changes in health status and dietary intakes due to shifts in demographic and socio-economic characteristics (DSEC) from that due to unobserved factors.

Background: Despite an increasing number of studies highlighting the health benefits of community gardening, the literature is limited by cross-sectional designs. The "JArDinS" quasi-experimental study aimed to assess the impact of community garden participation on the adoption of more sustainable lifestyles among French adults.

Methods: Individuals entering a community garden in Montpellier (France) in 2018 (n = 66) were compared with pairwise matched individuals with no experience in community gardening (n = 66).

Background: Ultra-processed food (UPF) consumption has increased drastically worldwide and already represents 50%-60% of total daily energy intake in several high-income countries. In the meantime, the prevalence of overweight and obesity has risen continuously during the last century. The objective of this study was to investigate the associations between UPF consumption and the risk of overweight and obesity, as well as change in body mass index (BMI), in a large French cohort.

Purpose: Despite the urgency regarding increasing rates of obesity and chronic diseases in the Caribbean, few studies described the nutrition transition. We aimed to provide such information by identifying dietary patterns in the French West Indies and their characteristics.

Methods: This cross-sectional analysis included 1144 Guadeloupeans and Martinicans from a multistage sampling survey conducted on a representative sample.

Background: Obesity and metabolic diseases represent a major health burden in the Caribbean, particularly since a large part of the population is disadvantaged. However, socioeconomic inequalities in chronic diseases are poorly explored in this region. We investigated the association between socioeconomic position and metabolic syndrome (MetS) prevalence and explored the contribution of diet quality to explain this association, among adults in the French West Indies.

Objective: This study examined the role of migration and acculturation in the diet of Ghanaian migrants in Europe by (1) comparing food intake of Ghanaian migrants in Europe with that of Ghanaians living in Ghana and (2) assessing the association between acculturation and food intake.

Design: Data from the cross-sectional multicenter study Research on Obesity and Diabetes among African Migrants were used. Food intake was assessed using a Ghana-specific food propensity questionnaire (134 items and 14 food groups); foods were grouped based on a model of dietary change proposed by Koctürk-Runefors.
