The statistical population studied in this study is rural households living in 3 villages (Fash, Nejoobran and Kandoleh) in the counties (Harsin, Sahneh and Kangavar) of Kermanshah province. To determine the desired sample in the present study, a random stratified sampling method was used and the sample size was estimated using the Cochran formula based on the number of households in the three villages studied, which is 259 people.
