At baseline, SNAP users had lower socioeconomic status and a greater number of chronic conditions than nonusers and were more likely to be lost to follow-up. Our multivariable IP-weighted models suggested that SNAP users had worse memory scores at baseline but slower rates of memory decline compared with nonusers (the annual decline rate is −0.038 standardized units [95% CI = −0.044 to −0.032] for users and −0.046 [95% CI = −0.049 to −0.043] for nonusers). Results were slightly stronger from the PS-matched sample (N = 1,014) (the annual decline rate was −0.046 units [95% CI = −0.050 to −0.042] for users and −0.060 units [95% CI = −0.064 to −0.056] for nonusers). Put in other words, our findings suggested that SNAP users had approximately 2 fewer years of cognitive aging over a 10-year period compared with nonusers.Discussion After accounting for preexisting differences between eligible SNAP users and nonusers as well as differential attrition, we find SNAP use to be associated with slower memory function decline.FPL=federal poverty level; HS=high school; HRS=Health and Retirement Study; IP=inverse probability; IPAW=IP attrition weight; IPTW=IP of treatment weight; PS=propensity score; SNAP=Supplemental Nutrition Assistance Program
