In 1989, communist rule was overthrown in Poland, one of the largest economies in Europe with a population of over 38 million(1), and the country successfully transformed itself into a booming capitalistic market economy. This led to rapid changes in lifestyle behaviour including increase in food accessibility and availability, the use of cars, the duration of television viewing and sedentary activity, changes which are typical of countries undergoing rapid economic and nutrition transition(Reference Popkin2).
A literature review was conducted to investigate if changes in the Polish economy were reflected in dietary intake and the prevalence of overweight and obesity pre- and post communism. The majority of the literature search was conducted in Poland using the Library of the Medical University of Gdansk as the primary source, and many of the papers had to be translated from Polish to English. Studies were included if appropriate dietary assessment tools of 3- to 7-d weighed diary and multiple 24 h recalls were used, and if anthropometric measurements were conducted using standardised procedures. A total of 25 studies were selected for review, which included six large cohort studies and 13 cross-sectional studies.
A review of four(Reference Charzewska3–Reference Ostrowska6) relatively large dietary intake studies showed that the average proportion of energy from fat intake increased from 36% in 1989 to 39% in 2003, and subsequently the proportion of energy from carbohydrate intake decreased from 50% to 47% during the same period. The proportion of energy intake from protein remained largely unchanged. The epidemiological evidence also revealed a gradual, but steady increase in adult mean BMI from 21.4 kg/m2 in 1971(Reference Koziel, Szklarska and Bielicki7)to 23.4 kg/m2(Reference Kułaga, Krzyżaniak and Palczewka8) in 2002. A similar pattern was observed in studies, which examined changes in BMI in children(Reference Kułaga, Krzyżaniak and Palczewka8–Reference Abramowicz, Białkoz-Kalinowska and Konstantynowicz10), rising from 15.6 kg/m2 in 1971 to 17.4 kg/m2 in 2002. This pattern was further emphasised in the increased prevalence of overweight and obesity in adults from 5.6% and 1% in 1971(Reference Chrzanowska, Koziel and Ulijaszek9) to 11.9% and 2.5% in 2001(Reference Koziel, Szklarska and Bielicki7), respectively. A more rapid increase was observed in the prevalence of overweight and obesity in children rising from 5.5% and 0.6% in 1971(Reference Chrzanowska, Koziel and Ulijaszek9) to 16.9% and 6%, respectively, in 2007(Reference Abramowicz, Białkoz-Kalinowska and Konstantynowicz10). It is evident that there is a growing body of evidence to show that Poland is in rapid nutrition transition and timely interventions to decrease risk from chronic disease may be necessary.
