Abstract: This thesis uncovers the long-term development of overweight and obesity prevalence
in the Czech Republic and finds the associations with relevant lifestyle risk factors and
determinants of health. Periodically collected interview and examination survey data
from 1993 to 2019 are standardised and used to perform a pooled analysis to inspect
trends within the cross-sectional units. The binomial logistic regression is used to
estimate changes in the odds of being overweight given a set of socio-economic and
lifestyle-related predictors, and to inspect time trends in their magnitude and
significance. Adjustment to historical data is calculated to account for methodological
changes in BMI classification scheme to ensure comparability of survey outcomes. In
addition, the response bias in self-reported anthropometric measurements is confirmed
and quantified. Finally, the most recent data (2019) for obesity rates are updated
accordingly to reflect this finding. The true prevalence of overweight in the Czech adult
population is calculated to 75.8% for men and 58.8% for women, which is higher than
interview survey results by 7.7 and 9.6 percentage points respectively. These adjusted
results may be utilised by users of survey outcomes to build their analyses on validated
data, together with other observations from the comprehensive overview of the
historical development of core health indicators, which is the first of its kind and scope
in the local environment.
