Objectives: To examine longitudinal pathways from multiple types of neighborhood restaurants and food stores to BMI, through dietary behaviors.

Methods: We used data from participants (n=5114) in the United States-based Coronary Artery Risk Development in Young Adults study and a structural equation model to estimate longitudinal (1985-86 to 2005-06) pathways simultaneously from neighborhood fast food restaurants, sit-down restaurants, supermarkets, and convenience stores to BMI through dietary behaviors, controlling for socioeconomic status (SES) and physical activity.

Results: Higher numbers of neighborhood fast food restaurants and lower numbers of sit-down restaurants were associated with higher consumption of an obesogenic fast food-type diet. The pathways from food stores to BMI through diet were inconsistent in magnitude and statistical significance.

Conclusions: Efforts to decrease the numbers of neighborhood fast food restaurants and to increase the numbers of sit-down restaurant options could influence diet behaviors. Availability of neighborhood fast food and sit-down restaurants may play comparatively stronger roles than food stores in shaping dietary behaviors and BMI.

Background: Apathy (loss of motivation or goal-directed behaviour) and depression each confer risk for dementia, cardiovascular disease and mortality in older adults. Mechanisms for this are not yet understood, and may involve systemic inflammation. However, this has received little attention, particularly in older adults where depression may present differently.

Background: This study aimed to explore the impact of the COVID-19 pandemic and resulting changes to diabetes care, especially concerning disease control, the use of (tele)consultation and lessons worth implementing to improve diabetes care, with a specific focus on ethnic minority groups.

Methods: A mixed-methods prospective cohort study among people with type 2 Diabetes Mellitus (T2DM) treated in primary care during the COVID-19 pandemic. A survey was sent regionally, including items related to teleconsultation and amount of contact with the healthcare professional.

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.
