TABLE 4—

Treatment Effect of SNAP Participation on Cost-Related Medication Nonadherence for All Older Adults, Those Threatened by Hunger, and Those Who Are Food Insecure: United States, 2013–2015

				Percentage Point Reduction in CRN Owing to SNAP^b
Sample	No.	% CRN Among SNAP Participants^a	% CRN Among Eligible Nonparticipants^a	% (SE)	95% CI
All older adults	4347	11.4	16.2	−4.8** (0.015)	−1.9, −7.7
Older adults threatened by hunger^c	1344	18.3	27.4	−9.1** (0.028)	−3.6, −14.7
Food-insecure older adults	886	21.5	28.9	−7.4* (0.036)	−0.3, −14.5

Note. CI = confidence interval; CRN = cost-related medication nonadherence; SNAP = Supplemental Nutrition Assistance Program. All regressions include a constant and all other covariates. For the full results from these models, see Table B, available as a supplement to the online version of this article at http://www.ajph.org. All regressions are weighted by the product of the propensity weight and the survey weight to produce nationally representative estimates.

^{^a}

Regression-adjusted CRN rates among participants and eligible nonparticipants.

^{^b}

The average marginal effect (robust standard error) estimated in the Probit regression model.

^{^c}

“Threatened by hunger” includes both marginally food-secure and food-insecure older adults.
