Design of the (FRESH) study: leveraging systems science to work with independently-owned restaurants to increase access to and promotion of healthful foods.

Background: High dietary quality can protect against diet-related chronic diseases. In the United States, racial and ethnic minorities and those with lower incomes consistently exhibit lower dietary quality. Independently-owned restaurants are a common prepared food source in minority low-income communities, but there are significant knowledge gaps on how to work with these restaurants to offer healthy food, due to underlying and dynamic complexities associated with providing healthy food options.

Support for Foods Allowed Under the Supplemental Nutrition Assistance Program.

Introduction: Millions of U.S. families rely on the Supplemental Nutrition Assistance Program (SNAP) to afford food.

The lived experience of Co-occurring food insecurity and food addiction: A qualitative study.

Household food insecurity affects 13.5% of US households and is associated with short and long-term negative health outcomes. Food addiction, which posits that highly processed (HP) foods may trigger addictive responses akin to substance use disorders (SUD), occurs in approximately 15% of adults.

Reinforced Borrowing Framework: Leveraging Auxiliary Data for Individualized Inference.

Increasingly during the past decade, researchers have sought to leverage auxiliary data for enhancing individualized inference. Many existing methods, such as multisource exchangeability models (MEM), have been developed to borrow information from multiple supplemental sources to support parameter inference in a primary source. MEM and its alternatives decide how much information to borrow based on the exchangeability of the primary and supplemental sources, where exchangeability is defined as equality of the target parameter.
