Participants were aged 18 to 30 years at baseline; design indicated equal recruitment by race (black vs white), educational attainment, age, and sex. Community-level price data from the Council for Community and Economic Research were temporally and geographically linked to study participants&#039; home address at each examination.<\/p>\n<p><strong>MAIN OUTCOMES AND MEASURES:<\/strong><\/p>\n<p>Participant-reported number of fast food eating occasions per week, body mass index (BMI), and homeostasis model assessment insulin resistance (HOMA-IR) from fasting glucose and insulin concentrations. Covariates included individual-level and community-level social and demographic factors.<\/p>\n<p><strong>RESULTS:<\/strong><\/p>\n<p>In repeated measures regression analysis, multivariable-adjusted associations between fast food price and consumption were nonlinear (quadratic, P &lt;&thinsp;.001), with significant inverse estimated effects on consumption at higher prices; estimates varied according to race (interaction P =&thinsp;.04), income (P =&thinsp;.07), and education (P =&thinsp;.03). At the 10th percentile of price ($1.25\/serving), blacks and whites had mean fast food consumption frequency of 2.20 (95% CI, 2.07-2.33) and 1.55 (1.45-1.65) times\/wk, respectively, whereas at the 90th percentile of price ($1.53\/serving), respective mean consumption estimates were 1.86 (1.75-1.97) and 1.50 (1.41-1.59) times\/wk. We observed differential price effects on HOMA-IR (inverse for lower educational status only [interaction P =&thinsp;.005] and at middle income only [interaction P =&thinsp;.02]) and BMI (inverse for blacks, less education, and middle income; positive for whites, more education, and high income [all interaction P &lt;&thinsp;.001]).<\/p>\n<p><strong>CONCLUSIONS AND RELEVANCE:<\/strong><\/p>\n<p>We found greater fast food price sensitivity on fast food consumption and insulin resistance among sociodemographic groups that have a disproportionate burden of chronic disease. Our findings have implications for fiscal policy, particularly with respect to possible effects of fast food taxes among populations with diet-related health disparities.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-59534","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Department of Nutrition, Gillings
