The present study is a descriptive-analytical and applied research conducted at national level using econometrics Heckman two-step model.

Higher education and employment of mothers have led to a decrease in the probability of household facing hospital expenditures, by 0.002% and 0.9%, respectively. Mother’s employment, having supplementary health insurance, and bachelor's or higher education of mother resulted in a decrease in per capita hospital expenditures of households by 2058123, 1361437 and 3647518 Rials, respectively. An increase in household size, having children under the age of seven and elderly persons over sixty years old, and mothers with elementary education led to an increase in household hospital expenditures by 1347241, 4406778, 1602637 and 1674286 Rials, respectively.
Regarding the greater impact of aging of mothers, compared to fathers, and having children and elderly persons in the household and increased hospital expenditures, protection and support of such households is necessary to achieve better health status and reduce household hospital expenditures, which  can be achieved through improving and discounting insurance coverage and preventive health care. Also, investing in education to provide an appropriate condition for education of most people in the community, as well as enhancing parental health literacy through health education, is recommended.
