Age- and gender-specific prevalence estimates of obesity based on complementary data sources and various definitions. For health survey (SHS) (a and b), we defined obesity as BMI ≥30 kg/m2 derived from self-reported height and weight. For primary care data (FIRE) (c and d), we defined obesity as BMI ≥30 kg/m2 derived from measured height and weight, and BMI ≥30 kg/m2 derived from measured height and weight or diagnosis of obesity. For hospital discharge statistics (MEDSTAT) (e and f), we defined obesity as ICD-10 code E66 as secondary diagnosis. Results based on less than 30 observations are marked by an asterisk.
