The socio-cultural exposome as a regulator of human growth
Background: Humans are social. The social environment is strongly associated with body height. Recent evidence emphasizes the role of social signalling in the regulation of human growth. Objective: To disentangle the influence of physical living conditions such as wealth, health, nutrition, and education from influences that are transmitted among group members. We analysed the impact of the group assuming a theoretical “transgenerational growth p…
Avoiding “Too Tall” and “Too Short”
BACKGROUND: Recent evidence emphasizes the role of social signaling in the regulation of human growth. AIM: To disentangle the influence of physical living conditions such as wealth, health, nutrition, and education from influences that are transmitted among members of the social group. We consider the spectrum of all historically possible heights ("transgenerational growth potential") and disentangle the influence of the physical living conditio…
Chain Reversion for Detecting Associations in Interacting Variables—St. Nicolas House Analysis
(1) Background: We present a new statistical approach labeled as "St. Nicolas House Analysis" (SNHA) for detecting and visualizing extensive interactions among variables. (2) Method: We rank absolute bivariate correlation coefficients in descending order according to magnitude and create hierarchic "association chains" defined by sequences where reversing start and end point does not alter the ordering of elements. Association chains are used to …

Community‐based clustering of height in Ethiopia, India, Peru, and Vietnam
OBJECTIVES: Human growth and final height are influenced by many factors such as genetics, nutrition, living conditions, socioeconomic background and, as recently proposed, by social peer groups and the community. In this paper, we aim to evaluate the extent to which spatial proximity, acting as a proxy for the social community, causes height clustering in low and middle income countries. MATERIAL AND METHODS: We analyzed data from the study "You…
Nonparametric Multiple Imputation for Questionnaires with Individual Skip Patterns and Constraints
Large-scale surveys typically exhibit data structures characterized by rich mutual dependencies between surveyed variables and individual-specific skip patterns. Despite high efforts in fieldwork and questionnaire design, missing values inevitably occur. One approach for handling missing values is to provide multiply imputed data sets, thus enhancing the analytical potential of the surveyed data. To preserve possible nonlinear relationships among…
Synthetic growth reference charts
OBJECTIVES: To reanalyze the between-population variance in height, weight, and body mass index (BMI), and to provide a globally applicable technique for generating synthetic growth reference charts. METHODS: Using a baseline set of 196 female and 197 male growth studies published since 1831, common factors of height, weight, and BMI are extracted via Principal Components separately for height, weight, and BMI. Combining information from single g…
The association of body height, height variability and inequality
Body height is associated with environmental conditions. It has been suggested that under poor conditions when inequality within a population increases, also the variability in height tends to increase. We studied the association of body height, within-country variability in height and geographic and historic origin in 767 growth studies carried out in 80 countries, published between 1794 and 2013, with data on N = 78,184 infants age 2 years, and…
Increasing prevalence of overweight and obesity among children in Vilnius, Lithuania
The aim of this study was to assess changes in prevalence of overweight and obesity among children born in 1996 and 1990 in Vilnius city. The results were based on comparison of two longitudinal data sets (N = 624 and N = 389) collected from the personal health records of children born in 1996 and 1990 respectively. No statistically significant differences in final height and BMI were established between children born in 1990 and 1996; however, b…
Sex, Sport, IGF-1 and the Community Effect in Height Hypothesis
We test the hypothesis that differences in social status between groups of people within a population may induce variation in insulin-like growth factor-1(IGF-1) levels and, by extension, growth in height. This is called the community effect in height hypothesis. The relationship between IGF-1, assessed via finger-prick dried blood spot, and elite level sport competition outcomes were analysed for a sample of 116 undergraduate men and women. Ther…
The impact of physical connectedness on body height in Swiss conscripts
BACKGROUND: Human populations differ in height. Recent evidence suggests that social networks play an important role in the regulation of adolescent growth and adult height. We further investigated the effect of physical connectedness on height. MATERIAL AND METHODS: We considered Switzerland as a geographic network with 169 nodes (district capitals) and 335 edges (connecting roads) and studied effects of connectedness on height in Swiss conscrip…
Diversity in auxology
Auxology has developed from mere describing child and adolescent growth into a vivid and interdisciplinary research area encompassing human biologists, physicians, social scientists, economists and biostatisticians. The meeting illustrated the diversity in auxology, with the various social, medical, biological and biostatistical aspects in studies on child growth and development.
Growth variation, final height and secular trend. Proceedings of the 17th Aschauer Soiree, 7th November 2009
Statistical agreement and cost–benefit
The analysis revitalizes the debate on clinically relevant and at the same time practicable but less demanding alternatives for constructing growth reference charts, and for economic reasons, strongly suggests replacing the traditional empirical methods by synthetic growth references
