In ۲۰۱۰, food subsidy program implemented since ۱۹۷۹ was replaced by unconditional cash transfer (CT) in Iran. The present pre-and-post evaluation study aims to compare food security and expenditures of urban households during the implementation of food subsidy and CT programs. Methods: Using a stratified cluster sampling method, ۲۶۶ households were selected from Tehran city. Data were collected in two phases: before (۲۰۰۹) and after (۲۰۱۲) implementing CT program using questionnaires including demographics; household expenditure; locally validated Household Food Insecurity Access Scale (HFIAS); and three consecutive ۲۴-hours diet recalls. Seven focus group discussions (FGDs) with women were also held. Results: After implementing CT program, the households' food and total expenditures increased and their family size decreased. Mild, moderate, and severe food insecurity increased from ۱۹.۳%, ۱۳.۳%, and ۱۱% to ۲۸.۴%, ۱۵.۵%, and ۱۲.۵%, respectively (P<۰.۰۰۱). There was a significant decrease in consumption of fat and oils and sugary food groups (time effect P<۰.۰۵). The consumption of fruits, meat, and dairy products was lower in the food insecure women than in the food secure ones (group effect P<۰.۰۵). However, the food secure and insecure households behaved differently in terms of only sugar consumption (time group effect P<۰.۰۵). Based on the FGDs, relative deprivation and social gaps increased. Conclusion: Considering the reduction in welfare index, targeting poor/vulnerable groups, as well as conditional CT could be considered in Iran
