Abstract

INTRODUCTION There are limited data on the current prevalence of overweight and obesity as well asits changes with time in Poland. OBJECTIVES The aim of the study was to assess the prevalence of general and abdominal obesity andoverweight in Polish adults in the years 2013-2014, and to compare it with the prevalence in the years2003-2005. PATIENTS AND METHODS The study was conducted in 2 independent, representative samples of thePolish population, comprising 14 537 persons (aged 20-74 years) examined in the years 2003-2005and 6164 persons (aged ≥20 years) examined in the years 2013-2014. Anthropometric measurementswere done by trained nurses. RESULTS In the years 2013-2014, the age-standardized prevalence of obesity (body mass index [BMI]≥30 kg/m2) was 24.4% in men and 25.0% in women. The prevalence of overweight (BMI, 25.0-29.9kg/m2) was 43.2% in men and 30.5% in women. Abdominal obesity (waist circumference ≥102 cm inmen or ≥88 cm in women) was noted in 32.2% of men and 45.7% of women. Abdominal overweight(waist circumference, 94-101.9 cm in men or 80-87.9 cm in women) was present in 27.2% of menand 21.7% of women. Since the years 2003-2005, the distribution of body mass according to the BMIcategory had shifted to higher values, and an increase in the prevalence of obesity was observed inmen. The percentage of adults with normal waist circumference decreased significantly in both sexes. CONCLUSIONS Every fourth inhabitant of Poland is obese, and during the last decade, the prevalence ofobesity has increased, particularly in men. Abdominal obesity is observed in every third man and nearlyevery second woman, and an excess of abdominal fat has increased in both sexes.
