Objective: We investigated the association between junk food consumption at lunchtime (JCL) and fast-food outlet access near school among secondary-school children in Quebec.
Design: A geographic information system database was used to characterize the food environment around a sub-sample of 374 public schools in which 26 655 students were enrolled. The outcome variable was JCL during the previous week, dichotomized into low JCL (none or once) v. high JCL (twice or more). Access to fast-food outlets near school was assessed using an existing database of fast-food outlets in Quebec. Covariates included student (age, sex and self-rated perceived health), family (familial status and parental education) and school (urban/rural status and deprivation) variables. Hierarchical logistic regression models were employed for analyses using PROC GLIMMIX of SAS version 9.3.
Setting: Province of Quebec, Canada.
Subjects: We used data from the Quebec Health Survey of High School Students (QHSHSS) 2010-11, a survey of secondary-school Quebec students.
Results: Exposure to two or more fast-food outlets within a radius of 750 m around schools was associated with a higher likelihood of excess JCL (OR=1·50; 95 % CI 1·28, 1·75), controlling for the characteristics of the students, their families and their schools.
Conclusions: The food environment surrounding schools can constitute a target for interventions to improve food choices among secondary-school children living in the province of Quebec. Transforming environments around schools to promote healthy eating includes modifying zoning regulations that restrict access to fast-food outlets around schools.

The built and natural environment can facilitate (un)healthy behaviors in adolescence. However, most previous studies have focused on examining associations between singular aspects of the environment. This study examined the association between the mixture of health-promoting and health-constraining environmental features in a Healthy Location Index (HLI) and physical activity and screen time among adolescents.

Background: The food environment plays a crucial role in shaping our dietary choices and overall health. Spatial measures provide distinct perspectives on the physical food environment and its impact on diet. While proportion measures are theoretically considered to provide a more accurate representation of the overall physical food environment than density measures, it is important to recognize that the association between food environments and diet can vary depending on the context.

Article Synopsis
- The study examines how socioeconomic position (SEP), food environments, walkability, and greenspace impact type 2 diabetes (T2D) risk, focusing on their interconnection.
- Lower SEP correlates with a higher risk of T2D, with significant hazard ratios indicating a strong link between education, income, occupation, and diabetes prevalence.
- Environmental factors only weakly mediate the relationship between SEP and T2D, suggesting that while lower SEP leads to a less healthy environment, this isn't the primary driver for increased diabetes risk.
Public acceptability of proposals to manage new takeaway food outlets near schools: cross-sectional analysis of the 2021 International Food Policy Study.

Global trends indicate that takeaway food is commonly accessible in neighbourhood food environments. Local governments in England can use spatial planning to manage the opening of new takeaway outlets in 'takeaway management zones around schools' (known sometimes as 'exclusion zones'). We analysed data from the 2021 International Food Policy Study to investigate public acceptability of takeaway management zones around schools.

Background: Takeaway food is often high in calories and served in portion sizes that exceed public health recommendations for fat, salt and sugar. This food is widely accessible in the neighbourhood food environment. As of 2019, of all local authorities in England (n=325), 41 had adopted urban planning interventions that can allow them to manage the opening of new takeaway outlets in "takeaway management zones around schools" (known elsewhere as "exclusion zones").
