About this study
Official title: Dietary Quality by At-home and Away-from-home Food Sources in the Supplemental Nutrition Assistance Program (SNAP)
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.
Read the detailed description
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Caloric intake
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.
Measured: 2003-2014
Solid fat
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.
Measured: 2003-2014
Added sugar
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.
Measured: 2003-2014
Non-starchy vegetables
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.
Measured: 2003-2014
Whole fruit
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.
Measured: 2003-2014
Whole grains
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.
Measured: 2003-2014

The record says: finished, as of the sponsor's last update on 13 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Caloric intake (time frame: 2003-2014). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Dec 2017.
