“…The authors concluded that the outcome was some sort of artifact. However, the veracity of their conclusions was later confirmed by Hulanicka (1986;Hulanicka et al 2001), Popczyk (1990) and Cichocka et al (2012). The results of researches indicated that the severe stress caused by family conflicts accelerates maturation.…”

“…The publication of Radochońska et al (2006) brought however an error of method in the results of the AM, as all the girls examined were below 14.5 years of age and the girls with delayed puberty were not considered. In the research conducted on 9599 rural girls in 2001 (Łaska-Mierzejewska and Olszewska 2003) only 90% out of 633 14.5 years old girls menstruated, whereas 95.6% result was noted by Cichocka et al (2012) in the group of girls of the same age from the city of Cra- cow. It was in the group of 17.5-year-olds where all the participants from quoted publications began menstruating.…”

“…The rural inhabitants decide to divorce three times less frequently than city residents, however for their children the trauma is undoubtedly more severe because of stronger community disapproval. Cichocka et al (2012) conclude, referring to the Demographic Yearbooks that about 20-28% of children grow in families with disturbed structure, and such proportion may lower the mean age at maturation calculated for the total number of children. Cichocka and Żarów (2002) emphasize the relationship between the divorce rate and the age at menarche in three Polish cities.…”

The aim of the study is to present social distances in biological development of youth in the period of changes in economic and political situation in Poland.Material and methods: 1. Nationwide study of children and adolescents aged 7.5 to 19.5 years started in 1979 and repeated every decade till 2009, 2. Survey conducted in the region of eastern Poland in 1987 and 2007, 3. Study of rural girls repeated four times between 1967 and 2001. The differences in body height and age at menarche between the inhabitants of towns and rural areas, as well as the differences between rural girls determined by diversified source of income for the family, will be presented. The age at menarche (AM) in each study was calculated using probit method. A monotonic decrease in body height differences between the inhabitants of towns, and girls living in rural areas was observed. On the basis of nationwide studies arithmetic means of the differences in terms of age were 1.9 cm in 1979 and 0.82 in 2009. At the same time, differences in the AM among girls in compared agglomerations decreased from 0.36 to 0.26, respectively. In eastern region of Poland the difference in body height between the residents of towns and villages in 1987 was 1.76 cm, and in 2007, only 0.38 cm; the difference of AM decreased from 0.41 to 0.14 years.The research conducted on inhabitants of rural areas has shown the earliest maturation and slightly greater body height for girls from landless families and the latest maturation and the smallest body height for the daughters of farmers. The differences in AM between the two groups decreased from 0.53 years in 1967 to 0.15 in 2001.The political transformation (1989) unequally influenced people on different levels of urbanization, different socio-professional groups and residents of various regions of the country, but was reflected in the results of anthropological research.The largest social advancement measured in terms of acceleration of maturation in the period covered by the research was characteristic for rural girls, especially the daughters of farmers.

Reliability of retrospective assessment of the age of first menstruation

The age of the first menstruation is one of the indicators for assessing the course of puberty. It is also a sensitive indicator of the economic situation of individual professional groups or societies, and the low average age of menarche is widely recognized as a marker of society’s well-being. The aim of the study was to analyse the reliability of the retrospective method of assessing the age at menarche by comparing the results to the age obtained from continuous research. Data regarding the age at menarche came from longitudinal somatic development and physical fitness studies conducted between 1976 and 2022. In 2022, 47 women were examined. In continuous studies, the prospective method was used in the assessment of the age of first menstruation while in the 2004 and 2022 studies a retrospective method was applied. Only in 4 out of 47 women the age of the first menstruation declared in 2004 and 2022 (the women were 32–34 and 50–52 years old, respectively) was consistent with the one found in continuous studies. In other cases, there was a discrepancy between the age found in continuous studies and self-reported in 2004 or 2022 or between the age stated in 2004 and 2022. Of those women who were present for the 2022 study, 36 had information about the age of first menstruation from continuous studies and the age of menarche in 2004 was given. For this sample the arithmetic mean and the standard deviation of the age at menarche were calculated. It was found that the retrospective method often used in the assessment of the age of the first menstruation is not fully reliable, as the average discrepancy in the assessment ranged from nearly 1 month (0.05 years) to over 2 months (0.19 years) compared to the prospective method. Women surveyed in 2004 determined the age of the first menstruation more accurately compared to statements obtained 18 years later from the same women. This study suggests that long-term memory (LTM) of a significant life event of every woman is unreliable, as indicated by the difference in the declared age of the first menstruation of women examined in 2004 and 2022, which, in individual cases, was up to 3, 4 or 5 years.
