title: Obesity. An analysis of epidemiological and prognostic research.
abstract: BACKGROUND
  Apart from its medical dimension, the current problem with obesity has acquired social urgency. This serious lifestyle disease has a negative impact on a number of life processes in the body, causing distortions and damaging different structures. It also contributes to clinical complications, lowers the quality of life and reduces life expectancy. Apart from health-related consequences, it can bring such unfavourable results as social, mental and emotional disorders.
  
  
  METHODS
  A systematic review of relevant epidemiological studies on obesity in Poland relative to selected countries in Europe and the world over the past 15 years was conducted. Also an attempt was made at forecasting the development of the obesity problem.
  
  
  RESULTS
  The analysed results demonstrated that the percentage of obese people among the adult population of Poland was on the rise in the period under investigation. Taking into account the estimated growth rate, we can assume that the percentage of obese people in Poland right now might total 23.7% for men and 23.3% for women. If no changes are introduced in this respect, in 2020 we can expect a rise to, respectively, 30.3% and 27.3%, and in 2030 to 37% for men and 31.4% for women.
  
  
  CONCLUSIONS
  The increase in the percentage of obese people among the adult population in Poland is most likely connected with a positive energy balance. In comparison to other European countries Poland has the highest percentage of obese men and women.
