TY - JOUR A1 - Hermanussen, Michael A1 - Weick, Stefan A1 - Scheffler, Christiane T1 - Severe postwar malnutrition did not have a negative impact on the earnings and subsequent pensions of German men born in 1945-1948 JF - Acta paediatrica : nurturing the child N2 - Aim: Poverty has often been associated with malnutrition, stunted growth, impaired cognitive development and poor earnings. We studied whether these associations were found in German men born and raised shortly after World War II during severe and long-standing nationwide malnutrition. Methods: We analysed German old-age pension payments, as a rough measure of lifetime earnings, in German men born from 1932 to 1960 and compared the at-risk-of-poverty rates of German men born in 1945-1948 versus 1935-1938 and 1955-1958. Results: Substantially fewer women worked during this period and their longer life expectancy makes their pension payments difficult to interpret. We therefore limited our analysis to men. Men born in the 1930s received the highest monthly old-age pensions and these declined slightly in men born from 1945 to 1948, indicating a minute impairment in work-related income in cohorts born shortly after the war. We also found that there was no evidence for increased at-risk-of-poverty rates in men born in 1945-1948 versus those born in 1935-1938 and in 1955-1958. Conclusion: Being born and raised following World War II was associated with a minute work and pension impairment that was not visible in the at-risk-of-poverty rates. These findings question statements associating early childhood nutrition and future lifetime earnings.

Proceedings of the 23rd Aschauer Soiree, Held at Aschauhof, Germany, November 7th 2015 T2 - Pediatric Endocrinology Reviews N2 - Twenty-four scientists met at Aschauhof, Altenhof, Germany, to discuss the associations between child growth and development, and nutrition, health, environment and psychology. Meta-analyses of body height, height variability and household inequality, in historic and modern growth studies published since 1794, highlighting the enormously flexible patterns of child and adolescent height and weight increments throughout history which do not only depend on genetics, prenatal development, nutrition, health, and economic circumstances, but reflect social interactions. A Quality of Life in Short Stature Youth Questionnaire was presented to cross-culturally assess health-related quality of life in children. Changes of child body proportions in recent history, the relation between height and longevity in historic Dutch samples and also measures of body height in skeletal remains belonged to the topics of this meeting. Bayesian approaches and Monte Carlo simulations offer new statistical tools for the study of human growth.

The aim of this study was to assess the temporal pattern in variability of menarcheal age for a historic Swiss population from the 19th and 20th centuries. ResultsMean menarcheal age declined from 17.34 years (n=358) around 1830 to 13.80 years (n=141) around 1950. Within-cohort variance decreased from 7.5 to 2.1 year(2). Skewness was negatively correlated with birth year (r=-0.58). ConclusionThis study provided evidence for a secular trend in various statistical parameters for age at menarche since the 19th century. Furthermore, the results of the analysis of temporal pattern in variability revealed that the secular trend in menarcheal age happened in two phases. Am. J. Hum. Biol. 28:705-713, 2016.

Methods: We re-analysed data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS study) on body height, body weight and body mass index based on the voice break, or mutation, in 3956 boys aged 10-17 years. We used the LMS method to construct smoothed references centiles for the studied variables in premutational, mutational and postmutational boys. Results: Body height, body weight and BMI differed significantly (p < 0.001) between the different stages of voice break. On average, boys were 5.9 cm taller, 5.8 kg heavier and had a 0.7 kg/m(2) higher BMI with every higher stage of voice break. Currently used growth references for chronological age in comparison with maturity-related references led to an average of 5.4% of boys being falsely classified as overweight.

Evidence in meerkats suggests that social dominance itself may be a strong stimulus for growth. Relative size serves as the signal for individuals to induce strategic growth adjustments. Aim: We construct a thought experiment to explore the potential consequences of the question: is stature a social signal also in humans? We hypothesize that (1) upward trends in height in the lower social strata are perceived as social challenges yielding similar though attenuated upward trends in the dominant strata, and that (2) democratization, but also periods of political turmoil that facilitate upward mobility of the lower strata, are accompanied by upward trends in height. Material and methods: We reanalyzed large sets of height data of European conscripts born between 1856-1860 and 1976-1980; and annual data of German military conscripts, born between 1965 and 1985, with information on height and school education. Results: Taller stature is associated with higher socioeconomic status. Historic populations show larger height differences between social strata that tend to diminish in the more recent populations. German height data suggest that both democratization, and periods of political turmoil facilitating upward mobility of the lower social strata are accompanied by a general upward height spiral that captures the whole population. Discussion: We consider stature as a signal. Nutrition, health, general living conditions and care giving are essential prerequisites for growth, yet not to maximize stature, but to allow for its function as a lifelong social signal. Considering stature as a social signal provides an elegant explanation of the rapid height adjustments observed in migrants, of the hitherto unexplained clustering of body height in modern and historic cohorts of military conscripts, and of the parallelism between changes in political conditions, and secular trends in adult human height since the 19th century.

Since our environmental factors are constantly changing because of anthropogenic influences, the question arises as to how far we have an impact on the human phenotype in the very sensitive growth phase in children and adolescents. Growth and development of all children and adolescents follow a universal and typical pattern. This pattern has evolved as the result of trade-offs in the 6-7 million years of human evolution. This typically human growth pattern differs from that of other long-living social primate species. It can be divided into different biological age stages, with specific biological, cognitive and socio-cultural signs. Phenotypic plasticity is the ability of an organism to react to an internal or external environmental input with a change in the form, state, and movement rate of activity (West-Eberhard 2003). The plasticity becomes visible and measurable particularly when, in addition to the normal variability of the phenotypic characteristics within a population, the manifestation of this plasticity changes within a relatively short time. The focus of the present work is the comparison of age-specific dimensional changes. The basic of the presented studies are more than 75,000 anthropometric data-sets of children and adolescence from 1980 up today and historical data of height available in scientific literature. Due to reduced daily physical activity, today's 6-18 year-olds have lower values of pelvic and elbow breadths. The observed increase in body height can be explained by hierarchies in social networks of human societies, contrary to earlier explanations (influence of nutrition, good living conditions and genetics). A shift towards a more feminine fat distribution pattern in boys and girls is parallel to the increase in chemicals in our environment that can affect the hormone system. Changing environmental conditions can have selective effects over generations so that that genotype becomes increasingly prevalent whose individuals have a higher progeny rate than other individuals in this population. Those then form the phenotype which allows optimum adaptation to the changes of the environmental conditions. Due to the slow patterns of succession and the low progeny rate (Hawkes et al. 1998), fast visible in the phenotype due to changes in the genotype of a population are unlikely to occur in the case of Homo sapiens sapiens within short time. In the data sets on which the presented investigations are based, such changes appear virtually impossible. The study periods cover 5-30 to max.100 years (based on data from the body height from historical data sets). N2 - Der anatomisch moderne Mensch Homo sapiens sapiens zeichnet sich durch eine hohe Anpassungsfähigkeit von Physiologie, Körperbau und Verhalten an sich kurzfristig ändernde Umweltbedingungen aus. Daraus ergibt sich die Frage inwieweit anthropogene Umweltbedingungen die sehr sensible Wachstumsphase von Kindern und Jugendlichen beeinflussen können. Das universelle und für den Menschen typische Wachstums- und Entwicklungsmuster mit unterschiedlichen biologisch, kognitiv und soziokulturell abgrenzbaren Entwicklungsstadien, welches sich in 6-7 Millionen Jahren menschlicher Evolution herausgebildet hat, unterscheidet sich von dem anderer langlebender sozialer Primaten. Phänotypische Plastizität ist die Fähigkeit eines Organismus sich in Form, Zustand, Aktivitätsrate oder Verhalten an unterschiedliche Umweltbedingungen anzupassen (West-Eberhard 2003). Beim Menschen wird diese Plastizität u.a. sichtbar, wenn sich anthropometrisch bestimmbare Merkmale im Vergleich von Populationen in relativ kurzer Zeit ändern. Der Schwerpunkt der vorliegenden Arbeit ist es, altersspezifische Änderung von Körpermaßen (Skelettbreiten, Körperendhöhe und Fettverteilungsmuster) aufeinanderfolgender Populationen in Abhängigkeit von neuen Umweltparametern zu vergleichen. Dem liegen ca. 75 000 anthropo-metrische Datensätzen von Kindern und Jugendlichen seit 1980 bis heute und historische Datensätze aus der Literatur zugrunde. Aufgrund verringerter alltäglicher Bewegung haben heutige 6-18-Jährige geringere Werte der Becken- und der Ellenbogenbreiten. Die beobachtete Zunahme der Körperhöhe lässt sich entgegen früherer Erklärungen (Einfluss von Ernährung, guter Lebensbedingungen und Genetik) durch Hierarchien in sozialen Netzwerken menschlicher Gesellschaften erklären. Eine Verschiebung zu einem eher weiblichen Fettverteilungsmuster bei Jungen und Mädchen findet sich parallel zur Zunahme von Chemikalien in unserer Umwelt, die das Hormonsystem beeinflussen können. Die beschriebene Plastizität des Phänotyps findet im Rahmen des genetisch manifestierten Wachstumsmusters bei Kindern und Jugendlichen statt. Epigenetische Einflüsse können nicht ausgeschlossen werden, sind aber an Körpermaßdaten per se nicht bestimmbar. Die Veränderung der analysierten Körpermaße unterstreicht, dass der Phänotyp des Menschen sich an veränderte Umweltbedingungen sehr plastisch anpassen kann. Wegen der langsamen Generationenfolge und Entwicklung des Menschen sind derartige eigentlich kurzfristige Veränderungen nur über einen Zeitraum von mindestens 5-30 Jahren zu beobachten.

Parallel to the decrease in physical activity and locomotion, modern people are slimmer in skeletal proportions. In German children and adolescents, elbow breadth and particularly relative pelvic breadth (50th centile of bicristal distance divided by body height) have significantly decreased in recent years. Even more evident than the changes in pelvic morphology are the rapid changes in body height in most modern countries since the end-19th and particularly since the mid-20th century. Modern Japanese mature earlier; the age at take-off (ATO, the age at which the adolescent growth spurt starts) decreases, and they are taller at all ages. Preece-Baines modelling of six national samples of Japanese children and adolescents, surveyed between 1955 and 2000, shows that this gain in height is largely an adolescent trend, whereas height at take-off (HTO) increased by less than 3 cm since 1955; adolescent growth (height gain between ATO and adult age) increased by 6 cm. The effect of globalization on the modern post-war Japanese society ("community effect in height") on adolescent growth is discussed.

Screening strongly relies on the concept of "normal values". Normal values are defined as values that are frequently observed in a population and usually range within certain statistical limits. Screening for obesity should start early as the prevalence of obesity consolidates already at early school age. Though widely practiced, measuring BMI is not the ultimate solution for detecting obesity. Children with high BMI may be "robust" in skeletal dimensions. Assessing skeletal robustness and in particularly assessing developmental tempo in adolescents are also important issues in health screening. Yet, in spite of the necessity of screening investigations, appropriate reference values are often missing. Meanwhile, new concepts of growth diagrams have been developed. Stage line diagrams are useful for tracking developmental processes over time. Functional data analyses have efficiently been used for analysing longitudinal growth in height and assessing the tempo of maturation. Convenient low-cost statistics have also been developed for generating synthetic national references.

The reasons for this phenomenon, as well as its outcomes, are undetermined so far. Aim: The present study explores the association between anthropometric skeletal measurements, bone quality measurements, and physical activity in young adults. Subjects and Methods: 118 German young men (N=568; 19-25 years old) and women (N=550; 19-24 years old) were investigated by anthropometric methods (i. e., height, weight, shoulder, elbow breadth, and pelvic breadth) and quantitative ultrasound measurement (QUS). Strength and stability of Os calcis have been determined by speed of sound (in m/s) and broadband ultrasound attenuation (in dB/Mhz); individual physical activity was analyzed by a pedometer and by questionnaire. Results: The results show a correlation between sports hours per week and bone quality index in males. But no correlation exists between anthropometric data and QUSs for either sexes, as well as no correlation between total steps per day and internal bone quality or external bone dimensions. Conclusion: These results are discussed in the context of generally decreasing physical activity, the outcomes of prevention programs as well as evolutionary adaptation of human phenotypic plasticity in a changing environment.

We aimed to develop references for body height, body weight and body mass index (BMI) with respect to tempo of maturity. Methods Data obtained from the German KiGGS study (2003-2006) on body height, body weight and presence or absence of the menarche were re-analysed in 3776 girls, aged 10-17years. We developed smoothed centiles for BMI-, body-height- and body-weight-for-age using the LMS method for premenarcheal and postmenarcheal girls. Results Body height, body weight and BMI differed significantly between premenarcheal and postmenarcheal girls. On average, postmenarcheal girls aged 11-17years were 5.3cm taller and 9.7kg heavier, and their BMI was 2.9kg/m2 higher than in premenarcheal girls of the same calendar age. Conclusion Adolescent BMI rises with calendar age and biological age. New reference charts for adolescent girls aged 10-18years were generated to be inserted into the currently used references to avoid misclassifying underweight and overweight pubertal girls.

JF - American journal of human biology : the official journal of the Human Biology Council N2 - Objectives: Modern human life style has led to significant decrease in everyday physical activity and bipedal locomotion. It has previously been shown that skeletal robustness (relative elbow breadth) is associated with daily step counts. The aim of the study was to investigate whether also other skeletal measures, particularly pelvic breadth may have changed in recent decades. Methods: We re-analyzed elbow breadth, pelvic breadth (bicristal), and thoracic depth and breadth, of up to 28,975 healthy females and 28,288 healthy males aged 3-18 years from cross-sectional anthropological surveys performed between 1980 and 2012 by the Universities of Potsdam and Berlin, Germany. Results: Relative elbow breadth (Frame index) significantly decreased in both sexes since 1980 (< 0.001). The trend toward slighter built was even more pronounced in absolute and relative pelvic breadth. In contrast, equivalent changes of parts of the skeletal system that are not involved in bipedal locomotion such as thoracic breadth, thoracic depth, and the thoracic index were absent. Conclusions: The present investigation confirms the decline in relative elbow breadth in recent decades. Analogue, but even more pronounced changes were detected in pelvic breadth that coincides with the modern decline in upright locomotion. The findings underscore the phenotypic plasticity of humans while adapting to new environmental conditions. (C) 2014Wiley Periodicals, Inc.

Anthropometric data were obtained in 289 German children (146 boys, 143 girls) aged 6-11 years and 41 20-29 year old German female students for describing the type of body shape by Metric-Index (thoracic breadth, thoracic depth, height). The data were correlated with 15 fat layers measured with a lipometer with Principal Component Analyses and ANOVA. In females the android respectively gynoid type of body shape was significantly associated with the pyknomorphic respectively leptomorphic type. The study demonstrates that this pattern is established by an age of 8 years, when the earliest maturing children start to enter puberty. This pattern can be used to check the individual's risk of overweight and to recommend preventive healthcare interventions.

Focusing on this issue, BMI and percentage of body fat were compared in 2094 schoolchildren from two cross-sectional studies from India and Germany investigated in 2008 and 2009. The German children are in all age groups significantly taller, whereas the Indian children show higher values in BMI (e.g. 12 years: Indian: around 22 kg/m(2); German: around 19 kg/m(2)) and in the percentage of body fat (e.g. 12 years: Indian: around 27 %; German: around 18-20%) in most of the investigated age groups. The Indian children have significantly higher BMI between 10 and 13 (boys) respectively 14 years (girls). Indian children showed significant higher percentage of body fat between 10 and 15 years (boys) and between 8 and 16 years (girls). The difference in overweight between Indian and German children was strongest at 11 (boys) and 12 (girls) years: 70 % of the Indian but 20% of the German children were classified as overweight. In countries such as India that undergo nutritional transition, a rapid increase in obesity and overweight is observed. In contrast to the industrialized countries, the risk of overweight in developing countries is associated with high socioeconomic status. Other reasons of the rapid increase of overweight in the developing countries caused by different environmental or genetic factors are discussed.

The analysis of facial dimensions is essential for identifying individual features also for forensic issues. The analysis of facial proportions was performed on photogrammetric data from front views of 125 children. The data were pooled from 2 different studies. The children's data were obtained from a longitudinal study and reduced by random generator to ensure the data of adults from a separate cross-sectional study. We applied principal component analysis on photogrammetric facial proportions of 169 individuals: 125 children (63 boys and 62 girls) aged 2-7 years and 44 adults (18 men and 26 women) aged 18-65 years. Facial proportions depend on age and sex. Three components described age: (1) proportions of facial height to head height, (2) proportions that involve endocanthal breadth, and (3) bigonial to bizygonial proportions. Proportions that associate with sex are connected with nasal distances and nasal to bizygonial distances. Twenty-three percent of the variance, particularly variance that are connected with proportions of lower and middle face heights to head height, do neither depend on sex nor on age and thus appear useful for screening purposes, eg, for dysmorphic genetic syndromes.

The aim of this investigation was to determine and evaluate the instrument's precision, as well as its manageability within anthropometric field studies. Data collected by the digital laser rangefinder did not show a significant difference to data of control by an anthropometer. Furthermore, more than 96% of the difference values are located within area of agreement. Nevertheless, the GLM Professional (R) is a highly sensitive instrument and mean SD within threefold data acquisition is twice as high as SD resulting from data collection by an anthropometer. However, due to the minimal percentage differences within data acquisition and compared to the standard method, the GLM Professional (R) is proved to be a reliable instrument and to be highly applicable for anthropometric field studies. Furthermore, due to its excellent manageability and compact size, the GLM Professional (R) shows a very good applicability even for less trained anthropometrists and thus ameliorates the possibilities of collecting reliable data within anthropometric field studies.

JF - American journal of human biology : the official journal of the Human Biology Council N2 - Objectives Childhood obesity is a global problem, e.g., due to physical inactivity. External skeletal robustness (Frame-Index) has decreased in German schoolchildren. An association between Frame-Index and physical activity was assumed. Further often body mass index (BMI) is analyzed without reference to bone structure. Therefore, we analyze relationships between Frame-Index, BMI, % body fat, and physical activity. Methods In a cross-sectional study, 691 German children aged 610 years were investigated. BMI, % body fat, Frame-Index, total steps p.w., sports club rate p.w., training time p.d., and TV-time p.d. were determined. Results Total steps (P<0.001), BMI (P<0.001), and % body fat (P=0.024) are positively linked to Frame-Index. Total steps (P<0.001), sports club rate (P=0.001), and training time (P<0.001) are negatively associated with % body fat. Total steps (P=0.017) are negatively linked to BMI. TV-time is positively related to BMI (P<0.001) and % body fat (P<0.001). % Body fat is affected by age (P<0.001), sex (P=0.028), and total steps (P=0.002). BMI is influenced by age (P<0.001), and Frame-Index by sex (P<0.001) and total steps (P=0.029). Principal component analysis indicates an association between BMI and TV-time and Frame-Index and total steps. Conclusions We demonstrate an association between external skeletal robustness and physical activity, which is not captured by in BMI measurements.

Physical activity affects the external skeletal robustness which decreased in German children. It was assumed that the negative trend of decreased external skeletal robustness can be found in other countries. Therefore anthropometric data of Russian and German children from the years 2000 and 2010 were compared. Methods: Russian (2000/2010 n = 1023/268) and German (2000/2010 n = 2103/1750) children aged 6-10 years were investigated. Height, BMI and external skeletal robustness (Frame-Index) were examined and compared for the years and the countries. Statistical analysis was performed by Mann-Whitney-Test. Results: Comparison 2010 and 2000: In Russian children BMI was significantly higher; boys were significantly taller and exhibited a decreased Frame-Index (p = .002) in 2010. German boys showed significantly higher BMI in 2010. In both sexes Frame-Index (p = .001) was reduced in 2010. Comparison Russian and German children in 2000: BMI, height and Frame-Index were different between Russian and German children. German children were significantly taller but exhibited a lower Frame-Index (p<.001). Even German girls showed a significantly higher BMI. Comparison Russian and German children in 2010: BMI and Frame-Index were different. Russian children displayed a higher Frame-Index (p<.001) compared with Germans. Conclusions: In Russian children BMI has increased in recent years. Frame-Index is still higher in Russian children compared with Germans however in Russian boys Frame-Index is reduced. This trend and the physical activity should be observed in the future.

A1 - Lieberman, Leslie Sue T1 - Growth variation, final height and secular trend : proceedings of the 17th Aschauer Soiree, 7th November 2009 N2 - Growth and body height have always been topics interesting to the public. In particular, the stupendous increase of some 15-19 cm in final adult height during the last 150 years in most European countries (the "secular trend"), the concomitant changes in body and head proportions, the tendency towards early onset of sexual maturation, the changes in the age when final height is being reached, and the very recent trend in body mass index, have generated much scientific literature. The marked plasticity of growth in height and weight over time causes problems. Child growth references differ between nations, they tend to quickly become out of date, and raise a number of questions regarding fitting methods, effects caused by selective drop-out, etc. New findings contradict common beliefs about the primary importance of nutritional and health related factors for secular changes in growth. There appears to be a broad age span from mid-childhood to early adolescence that is characterised by a peculiar insusceptibility. Environmental factors that are known to influence growth during this age span appear to have only little or no impact on final height. Major re- arrangements in height occur at an age when puberty has almost been completed and final height has almost been reached, implying that factors, which drive the secular trend in height, are limited to early childhood and late adolescence.

In view of the rising interest in reliable biometric kephalofacial data, we focussed on head and face measurements. Out of 34 classic facial anatomical landmarks, 27 landmarks were investigated both by direct anthropometry and 2D-photogrammetry; 7 landmarks could not be localized by 2D-photogrammetry. Twenty-six kephalofacial distances were analysed both by direct anthropometry and digital 2D-photogrammetry. Kephalofacial distances are on average 7.6% shorter when obtained by direct anthropometry. The difference between the two techniques is particularly evident in total head height (vertex-gnathion) due to the fact that vertex is usually covered by hair and escapes from photogrammetry. Also the distances photographic sellion-gnathion (1.3 cm, i. e. 11.6%) and nasal-gnathion (1.2 cm, i. e. 9.4%) differ by more than one centimetre. Differences below 0.5 cm between the two techniques were found when measuring mucosa-lip-height (2.2%), gonia (3.0%), glabella-stomion (3.9%), and nose height (glabella-subnasal) (4.0%). Only the estimates of forehead width were significantly narrower when obtained by 2D-photogrammetry (-1.4 cm, -13.1%). The methodological differences increased with increasing magnitude of the kephalometric distance. Apart from these limitations, both techniques are similarly valid and may replace each other.

Twentynine German studies with n > 200 subjects published since 1848 on menarcheal age, were reanalyzed, and 101 studies from various other European and non-European countries. On average, mean age at menarche declined since the mid-19(th) century. Historic urban samples tended to decline earlier than rural groups, upper class women earlier than working class women. In Germany, minimum values for the age at menarche were seen already between the two World Wars (Leipzig 12.6 years in 1934, Halle 13.3 years in 1939). Values for mean age and SD for age at menarche were strongly associated. With improving historic circumstances, the two parameters declined in parallel. The standard deviation for menarcheal age dropped from over 2.5 years in mid-19th century France to little more or even less than 1 year in most modern countries. In the German studies the correlation between menarcheal age and SD was almost complete with r = 0.96 (y = 0.35x - 3.53). Similar associations between mean age at menarche and SD for age were found in other European countries. The obvious and immediate effects of historic events on menarcheal age, and particularly on the age distribution, indicate that menarche is a sensitive indicator of public health and wealth, and may be an appropriate estimator for the socio-economic background of historic populations.

The aim of this study was to detect a critical age for exceeding weight gain. It is assumed that especially in the early years of life, the years of nursery school age, the individual development of weight is fundamental for the prediction of obesity. The data of 638 children (324 boys and 314 girls) and the data of additional 1390 children of a preceding longitudinal study were analysed. The results show that overweight newborns are not at higher risk of becoming overweight children later, in the first place. But the results identify a high risk of becoming overweight for children 4.5 years old through a BMI rebound. In addition, this comparably earlier BMI rebound is linked with an increasing percentage of body fat. This leads to the assumption, that a comparably early BMI rebound is remarkably atypical for healthy child development. The results are also interrelated with the test person's sex. Endangered girls are of pyknomorphic body type. In contrast, the boys' results are independent of the body type. Obesity of boys therefore is strongly assumed to be caused by environmental factors.

This combination models growth even in incomplete sets of data and in data obtained at irregular intervals. We re-analysed late 18th century longitudinal growth of German boys from the boarding school Carlsschule in Stuttgart. The boys aged 6-23 years, were measured at irregular 3-12 monthly intervals during the period 1771-1793. At the age of 18 years, mean height was 1652 mm, but height variation was large. The shortest boy reached 1474 mm, the tallest 1826 mm. Measured height closely paralleled modelled height, with mean difference of 4 mm, SD 7 mm. Seasonal height variation was found. Low growth rates occurred in spring and high growth rates in summer and autumn. The present study demonstrates that combining the principal component analysis and the maximum likelihood principle enables growth modelling in historic height data also.
