    Abstract:
    The age at menarche, body height and weight of the daughters of farmers, farmer-workers and landless villagers in a rural region of Poland were studied. In the period 1967-1977, a time of economic development, a decrease in age at menarche (by 0.74 years) and a secular trend in body height (by 2.4 cm/decade) was observed. In 1977-1987, a period of acute economic crisis, age at menarche increased by 0.16 years and the secular trend in body height was only 1.1 cm/decade. In 1987-2001, age at menarche decreased and body height increased by 0.28 years and 2.9 cm respectively. The percentage of families owning a car, freezer and video increased during this period. These last results are indicative of an improvement in living conditions, but the villagers regard themselves as losers as a result of the political transformation (1989) in Poland.
