RESUMO
AIMS: To evaluate the prevalence of diabetes and impaired fasting glucose in Poland in 2013-2014 and to determine the temporal trends between 2003-2005 and 2013-2014. METHODS: A questionnaire survey was conducted in a representative sample of Polish adults, complemented by anthropometric and fasting plasma glucose measurements. The research was part of the national cross-sectional WOBASZ study. Diabetes was assessed as self-reported or screened (fasting plasma glucose level ≥ 7 mmol/l, based on one blood sample). RESULTS: In the years 2013-2014 among 5694 participants aged 20-74 years, 6.0% (95% CI 5.4-6.6) reported a previous diagnosis of diabetes (5.8% in women and 6.2% in men). In addition, 2.4% of the participants (95% CI 2.0-2.8) without a previous diagnosis of diabetes (1.8% of women and 3.1% of men) had a fasting blood glucose level ≥7.0 mmol/l in a single measurement. In a single measurement, 18.4% of the participants (95% CI 17.4-19.4; 13.2% of women and 23.8% of men) had impaired fasting glucose. The prevalence of dysglycaemia in the WOBASZ II study was significantly higher compared to the WOBASZ I study findings from 2003-2005, increased from 6.6% to 8.4% for diabetes and from 9.3% to 18.4% for impaired fasting glucose (after age and sex standardization to the 2013 Polish population). CONCLUSIONS: The prevalence of diabetes in Poland is similar to that observed in other European populations and has increased significantly over the last decade.
