About this study

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.

Treatment and study plan

Primary outcomes

  1. Caloric intake

    Time frame: 2003-2014

    Number of calories consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

  2. Solid fat

    Time frame: 2003-2014

    Number of grams of solid fat and percent of intake from solid fat consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

  3. Added sugar

    Time frame: 2003-2014

    Number of grams of added sugar and percent of intake from added sugar consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

  4. Non-starchy vegetables

    Time frame: 2003-2014

    Cup-equivalent servings of non-starchy vegetables consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

  5. Whole fruit

    Time frame: 2003-2014

    Cup-equivalent servings of whole fruits consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.

  6. Whole grains

    Time frame: 2003-2014

    Ounce-equivalents of whole grains consumed by SNAP participants compared to nonparticipants in 2003-2006 and 2011-2014 by source of food (including grocery stores, fast food restaurants, sit-down restaurants and other sources). SNAP participants will be compared to income-eligible nonparticipants at income levels up to 200% of the federal poverty level.
