After the unification of East and West Germany the living conditions and the nutritional habits of the East German population changed considerably. The effects of these changes on nutritional status, physique and body composition are examined by a comparison of the representative sample of Greil taken from the East German population before the reunification of Germany with the sample of Trippo measured in the East German town of Potsdam between 1995 and 1997. The comparison of the samples of Greil and Trippo gives no indication of any increase in overweight subjects or adiposity during the last few years amongst the older test persons. However, the body mass of younger subjects shows a slight increase. Comparison of the estimates of total body fat showed considerable variation in results for skinfold thickness measurements and bioelectrical impedance analysis depending on the formula used.
