چکیده
مطالعه حاضر با هدف بررسی سطح اثرگذاری افزایش قیمت شدید مواد غذایی در سال 1397 بر الگوی تغذیه خانوار و نیز تعیین سطح آسیب پذیری مصرف کنندگان طراحی و انجام شد. بدین منظور، میزان آسیب پذیری خانوارهای شهری در شهرستان آزادشهر به عنوان یکی از بحرانی ترین مناطق استان گلستان به لحاظ امنیت غذایی مورد ارزیابی و تحلیل قرار گرفت. اطلاعات مورد نیاز از طریق تکمیل پرسشنامه هزینه خوراک و درآمد خانوار و با کمک مرکز بهداشت استان گلستان گردآوری شد. برای دستیابی به نتایج مطالعه، سیستم تقاضای تقریباً ایده آل درجه دوم به تفکیک دو گروه خانوارهای شهری با درآمد بالا و درآمد پایین برآورد شد؛ سپس، محاسبه شاخص آسیب پذیری خانوارها پس از افزایش قیمت مواد غذایی صورت گرفت. نتایج نشان داد که پس از افزایش قیمتها، خانوارها از نظر رفاهی در وضعیت وخیمی قرار گرفتهاند، به گونهای که شاخص آسیب پذیری برای خانوارها در گروه های درآمدی بالاتر و پایینتر از متوسط، به ترتیب، 04/15 و 4/25 محاسبه شد. این واقعیت لزوم حمایت از مصرف کنندگان برای بهبود امنیت غذایی و استاندارد زندگی را تاکید میکند.

چکیده [English]
This study aimed at investigating the effect of severe food price increases on family nutrition pattern in 2019 and determining the level of consumer vulnerability. For this purpose, the vulnerability of urban households in Azadshahr County as one of the most critical areas of Golestan province of Iran in terms of food security was evaluated and analyzed. The required information was collected through the questionnaire of food expenditure and household income and with the help of Golestan Health Center. In order to obtain the results, the Quadratic ideal demand system (QAIDS) was estimated by dividing the urban households with higher and lower average incomes. Then, the vulnerability index of the households was calculated after food price increase. The results showed that after rising prices, the households were in poor condition, so that the vulnerability index for the higher and lower income groups was 15.04 and 25.4, respectively. This fact emphasizes the need for consumer protection to improve food security and standard of living.
