简要总结
The objective of this cross-sectional study was to characterize the dietary intake of SNAP participants and nonparticipants by food source, including grocery stores, sit-down restaurants, and fast food.
详细描述
The study used 4,237 low-income adults from the National Health and Nutrition Examination Survey (NHANES) (2003-2006 and 2011-2014). De-identified data was collected from demographic questionnaires and 24 hour dietary recalls. We assessed intake of calories, solid fats, added sugars, and servings of non-starchy vegetables, whole fruits, and whole grains, by food source in SNAP participants and income-eligible nonparticipants. Associations between SNAP participation and dietary intake were analyzed using multivariate linear regression controlling for relevant sociodemographic characteristics.
