Few changes in food security and dietary intake from short-term participation in the supplemental nutrition assistance program among low-income Massachusetts adults.

摘要

Objective: To examine whether short-term participation in the Supplemental Nutrition Assistance Program (SNAP) affects food security and dietary quality among low-income adults recruited from a Massachusetts-wide emergency food hotline. Methods: A 3-month, longitudinal study was conducted among 107 adults recruited at the time of SNAP application assistance. Outcomes included household food security (10-item US Department of Agriculture Food Security Survey Module), dietary intake (eg, grains, fruit) and diet quality (modified Alternate Healthy Eating Index). Data were analyzed using paired t tests and multivariable linear regression. Results: Supplemental Nutrition Assistance Program participation was not associated with improved household food security over 3 months (P=.25). Compared with non-participants, SNAP participants increased refined grain intake by 1.1 serving/d (P=.02), from baseline to follow-up. No associations were observed with other foods, nutrients, or dietary quality. Conclusion and Implications: Policies that simultaneously improve household food security and dietary quality should be implemented to support the health of low-income Americans participating in this crucial program.
