1. Health expenditure in household budgets
of different socio-economic groups in Poland

2. The aim of the study is to assess the level of expenditure on health in different groups of households with particular attention paid to the households with relatively the best and worst financial situation. The aim is also to indicate the hierarchy of determinants of health expenditures depending on the financial situation of household members.

3. Materials
Individual data of the household budget survey by the Central Statistical Office of Poland (GUS) 2012.
The collection included more than 37 thousand households.

4. In the structure of health expenditure, there are three categories:
pharmaceuticals, medical devices (medical articles, therapeutic appliances and equipment, maintenance and repair services of therapeutic appliances and equipment);
outpatient services and services of alternative medicine (dental services, medical laboratories and X-ray laboratories, ancillary medical services, other health-related services);
hospital and sanatorium services.

5. Multiple regression analysis
Methods
Scheffe test.
It is one of the tests examining statistical significance which carries out a comparison of post-hoc. This is the most conservative test.
Multiple regression analysis
The overall objective of the multiple regression analysis is to investigate relationship between several independent variables and the dependent variable. The final model shows the "optimal" set of independent variables, assuming that construction of the model was successful, no potential variable was omitted, and the data is properly interpreted
