Vliv životního stylu na psychické zdraví obyvatel ČR podle dat šetření EHIS 2019

This bachelor's thesis deals with the analysis of the influence of selected lifestyle factors (healthy diet, physical exercise, alcohol consumption and use of tobacco products) on the mental health of respondents of the EHIS 2019 survey in the Czech Republic. The goal of the thesis is to establish initial hypotheses about the influence of each of the factors based on the literature and previous research, to examine the data available from the survey and to test the hypotheses using the data. The reason for the analysis is the greater emphasis placed on the monitoring of mental illnesses in society, and thus the effort to find out whether the physical habits of the respondents can also influence their mental state. Data from the survey are processed into contingency tables and described and all results are related only to respondents of the survey itself and not to the entire population of the Czech Republic. All variables are ordinal and thus hypotheses are tested using the chi-square test of independence in a contingency table and described using appropriate contingency measures. The research shows that the psychological health of the respondents is influenced by the factor of healthy diet, physical exercise and alcohol consumption, and the possible dependence of the factor of using tobacco products was not proven. The conclusion of the thesis describes the possible causes of these influences and the differences that can be observed between genders and age and educational groups of respondents for all factors that enter the analysis. The work also includes an explanation of interesting phenomena of source data and the calculation of indicators directly from the EHIS 2019 questionnaire.
