Background: An essential element of soldiers' efficiency and readiness to carry out tasks is their physical fitness, which is closely dependent on their body mass and composition, which in turn determine the proper functioning of the body. Subjects and methods: The aim of this study was to examine changes in physical fitness and body composition of students after a 4-week physical training. The study involved women (N=45) and men (N=45). Body com…
Relationship Between Self‐Reported Storytelling Ability and Reproductive Success Among Three Non‐Western Populations in Nigeria, Pakistan, and Papua
The association between storytelling ability and reproductive success appears context-dependent and may differ between egalitarian and hierarchical societies. Findings suggest that storytelling ability may be more strongly related to the likelihood of parenthood than to completed fertility in certain socioecological settings
Absence of Sex Difference in Digit Ratio ( 2D
The swimmers had lower 2D:4D than non-sporting individuals; the top level swimmers had the lowest 2D:4D. The female swimmers, particularly the elite group, showed "masculine" 2D:4D similar to their male counterparts. A plausible positive selection for a masculinised digit ratio (higher prenatal testosterone exposure) among the females in highly competitive professional sports was hypothesized
Social Mobility of the Father and Relative Body Weight of Offspring
This study identified age- and sex-related variation in the associations between intergenerational social mobility and BMI, contributing to a broader understanding of how intergenerational processes relate to physical development
Worldwide trends in underweight and obesity from 1990 to 2022

Social position in a peer group of school-aged boys and selected biological parameters
The period of adolescence includes biological, psychological and social maturation. All these processes complement and affect each other. The ultimate goal is the transition from childhood to adulthood which enables individuals to become socialized beings, who are psychologically mature and able to pass on their genetic inheritance. In the process of reaching full maturity, adolescents are exposed to both positive and negative stimuli the socio-c…
Differentiating effects of socio-economic factors on relative weight and nutritional status in Polish schoolchildren across intergenerational changes
Objective: The aim of this study was an assessment of the effects of urbanisation level, family size and parental education on body mass index (BMI) and mid-upper arm circumference (MUAC) among Polish schoolchildren in cross-sectional surveys conducted between 1966 and 2012. Design: The analysis involved schoolchildren measured in four Polish Anthropological Surveys (1966, 1978, 1988 and 2012). Socio-economic factors involved: urbanisation level …
Socio-economic determinants of the somatic development and reaction time of vegetarian and non-vegetarian children
Vegetarian diet affects the height, BMI and body fatness, as well as the reaction time in children at the age of 3-15.
Rising rural body-mass index is the main driver of the global obesity epidemic in adults
Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities 1,2 . This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity 3–6 . Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean B…
Is digit ratio (2D
The 2nd to 4th digit ratio (2D:4D) is a sexually dimorphic trait determined by the relative balance of prenatal testosterone (T) and oestrogen during the intrauterine development of foetus. Males on average have relatively lower 2D:4D than women in population. Lower 2D:4D is very often linked with greater physical ability, strength, superior sporting performance and many personality traits and behaviours which are seen more among the males. Recen…
Testing the Trivers-Willard Hypothesis on Polish kings and dukes
The Trivers-Willard Hypothesis (TWH), frequently investigated by evolutionary psychologists, states that human beings may have evolved to produce a greater number of sons when having a high status, and a greater number of daughters when having a low status. To test this hypothesis, we examined the sex of children of Polish high status: kings, dukes, magnates families; and of low status: peasants, burghers and gentry. Our findings do not provide e…

Influence of socioeconomic factors during adolescence on the menarcheal age in Central Poland girls
The purpose of the project was to indication the environmental factors that may influence on the menarcheal age in girls of Central Poland. The study was conducted in Warsaw and Lodz between 2016 and 2017 among subjects of randomly selected high schools, schools for adults, and workplaces. The material included 752 subjects between the ages of 16.00 and 29.23 years (mean age was 20.99 years). The questionnaire form provided information on the pla…
Further Evidence of an Association Between Low Second-to-Fourth Digit Ratio (2d
Males and females differ in their preference for occupations and sporting activities, and differ also in risk-taking attitudes. In addition to other explanations, prenatal hormone exposure has been implicated in these gender-associated differences. The ratio of the relative lengths of the second-to-fourth digits (2D:4D) is a proxy indicator of prenatal exposure to testosterone relative to oestrogen. The 2D:4D ratio has been found to be associated…
Sex differences in relationship between body composition and digit length ratio (2D
It is believed that the second to fourth finger length ratio is an indirect indicator of fetal testosterone levels. It is pointed out that there is a relationship between the 2nd to 4th finger length ratio and the body structure in women and men. Studies on the relationship between body composition and 2D:4D finger length among military students have not been carried out so far. The work aims to determine the dependence of body composition and th…
Parental smoking during pregnancy and head shape and size in school children
Smoking-induced chronic hypoxic effects on the growing foetus, indicated that both active and passive smoking during pregnancy seems to have persistent negative effects on children, going beyond foetal development and pre-natal growth restrictions
External skeletal robusticity of children and adolescents – European references from birth to adulthood and international comparisons
Background: In our modern world, the way of life in nutritional and activity behaviour has changed. As a consequence, parallel trends of an epidemic of overweight and a decline in external skeletal robusticity are observed in children and adolescents. Aim: We aim to develop reference centiles for external skeletal robusticity of European girls and boys aged 0 to 18 years using the Frame Index as an indicator and identify population specific age-r…
Waiting for Trivers and Willard
Parental investment theory has been put forward as a major evolutionary argument explaining male or female biased birth sex ratio, the Trivers‐Willard (T‐W) hypothesis, predicting that parents living in good circumstances will bias their investment to sons, whereas parents in poor circumstances will bias their investment toward daughters. Tests of the T‐W hypothesis on human beings have shown limited evidence for parents appearing to differentiat…

Overall trends vs. individual trajectories in the second‐to‐fourth digit (2D
Relatively slight overall changes in digit ratio in puberty and adolescence themselves are not inconsistent with the use of the 2D:4D ratio as an indirect marker of prenatal sexual differentiation. Nevertheless, individual changes in the ratios varied substantially in this study and differed from the average trends. Future studies should focus on the nature of interindividual developmental differences in the digit and metacarpal ratios
Influence of socioeconomic factors during adolescence on the menarcheal age in Central Poland girls

The effect of neighboring districts on body height of Polish conscripts
order neighbors than in another country (Switzerland) may be associated with differences in geography, since in Poland there are no natural barriers (e.g., mountains) and road infrastructure is well-developed.
Post-migration adaptation and age at menarche in the second generation of migrants
Age at menarche is one of the most important measures of sexual maturation in girls. Since it has a high level of ecosensitivity, early environmental stress may trigger early puberty. One of these stress factors may be parental stress caused by the change of living conditions related to migration and adaptation to the new environment. Therefore, the aim of this study was to investigate the relationship between parental migration status and the ti…
Mother's trauma during pregnancy affects fluctuating asymmetry in offspring's face
OBJECTIVE: Fluctuating asymmetry (FA) of paired body structures is considered to be a reliable measurement of developmental instability of humans. The aim of the study is to examine whether the mother's traumatic experience during pregnancy results in an increase of the level of fluctuating asymmetry of the structures of the face. METHODS: Average relative FA of six cephalometric traits was calculated in 269 boys aged 7-10 years from Lodz, Poland…
Isolation by distance between spouses and its effect on children's growth in height
Heterosis is thought to be an important contributor to human growth and development. Marital distance (distance between parental birthplaces) is commonly considered as a factor favoring the occurrence of heterosis and can be used as a proximate measure of its level. The aim of this study is to assess the net effect of expected heterosis resulting from marital migration on the height of offspring, controlling for midparental height and socioeconom…
Age at maturation, body structure and their relationship with socioeconomic factors
Socioeconomic and lifestyle factors may be helpful in some levelling of differences in the body structure between girls differing in the age at menarche, especially the level of stress and the education and profession of parents.
Impact of normal weight obesity on fundamental motor skills in pre-school children aged 3 to 6 years
centile of the MABC-2 norm. These findings are strongly alarming since indices like BMI are not able to identify normal weight obese individual. We recommend verifying real portion of normal weight obese children as they are probably in higher risk of health and motor problems than overweight and obese population due to their low lean mass.

Variation of height and BMI within school classes in 14-year-old children
] were standardized based on mean and SD of the whole population separately for boys and girls. The SDs of height and BMI in each class were tested by Student-t test for one sample to check the difference in comparison to population with SD equal 1. Additionally, the nested analysis of variance was used, where height and BMI were dependent variables, and classes were nested into schools. SDs of height and BMI within classes are significantly lowe…
Sexual dimorphism in growth in the relative length of the forearm and relative knee height during adolescence
There are numerous studies concerning sexual dimorphism in body proportions, but only a few have investigated growth in the relative length of particular segments of the upper and lower limbs during adolescence. The aim of the study is an assessment of sex differences of longitudinal growth in the relative length of the forearm and knee height among adolescents. Sample involved 121 boys and 111 girls, participants of the Wroclaw Growth Study, exa…
Sibling Composition and Household Room Sharing Are Associated with Menarcheal Status among Rural Bengalee Girls of West Bengal, India
Menarche, the first menstruation, is one of the most important events in a woman's reproductive life. The timing of menarche varies across populations and depends upon social interaction and family environment. It is also associated with several biological as well as social factors. The objective of this study was to explore the relationship between sibling composition and age at menarche (AAM) and to assess the association between the pattern of…
Variation in subcutaneous adipose tissue distribution associated with age, sex, and maturation
Variation in subcutaneous adipose tissue distribution associated with age, sex, and maturation
Age-, sex-, and maturity-associated variation in subcutaneous adipose tissue (SAT) distribution is reviewed and then considered longitudinally in a sample of Polish youth. Current study of adipose tissue distribution places considerable emphasis on abdominal adiposity, specifically intra-abdominal or visceral adipose tissue (VAT). Most studies of children and adolescents do not include an abdominal skinfold, and when it is available, the skinfold…

Variation in relative fat distribution associated with maturational timing
Complete longitudinal data of 136 boys aged 8-16 years and 124 girls aged 8-15 years were used to evaluate the association between maturational timing and the relative distribution of subcutaneous adipose tissue, specifically a trunk-oriented pattern of distribution. Age at peak height velocity (PHV) was the indicator of maturational timing and three skinfolds (triceps, subscapular, abdomen) were the indicators of subcutaneous fatness. Principal …
Village distance from urban centre as the prime modernization variable in differences in blood pressure and body mass index of adults of the Purari delta of the Gulf Province, Papua New Guinea
Distance to urban centre appears to have a strong effect, relative to other modernization variables, on BMI and blood pressure, this effect being far stronger for males than for females. In large part, this effect operates by way of differences in number of sources of income as well as number of close relatives of women who are resident in an urban centre. Reasons for the male-female differences observed may include gender differences in degree o…

Influence of Height on Attained Level of Education in Males at 19 Years of Age
In this study it is hypothesized that taller individuals are more likely to move up the scale of educational attainment compared with shorter individuals from the same social background. Three national cohorts of 19-year-old males were considered: 29,464 born in 1967 and surveyed in 1986, 31,062 born in 1976 and surveyed in 1995, and 30,851 born in 1982 and surveyed in 2001. Four social variables were used to describe the social background of eac…
Socioeconomic Status During Childhood and Health Status in Adulthood
It has been widely observed that socioeconomic status (SES) is associated with frequency of cardiovascular disease. Both men and women of low socioeconomic position have increased risk of cardiovascular disease morbidity and premature death. In this study the relationship between SES in childhood, and health status at the age of 50 years was examined. Socioeconomic status in childhood was measured using objective (father’s educational level and n…

The effects of fatness and fat distribution on respiratory functions
Background: Inverse relationships between respiratory function and indices of obesity and fat distribution have been reported, but it remains unclear which measure of obesity shows the strongest relationship with lung function.Aim: The study assessed the effect of fatness and fat distribution on respiratory function.Subjects and methods: A sample of 423 males and 509 females aged 40–50 years were examined in the Silesian Centre for Preventive Med…
Inter-Generation Social Mobility Modifies Framingham Risk Score in Polish Middle-Aged Men, but Not in Women
In modern societies, there are regular social gradients in most health parameters, and also in the structure of morbidity and mortality. However, the significance of inter-generation social mobility for general health status still remains equivocal. This study was therefore performed in order to compare the effect of social mobility on coronary heart disease (CHD) risk between middle-aged Polish men and women. A total of 342 men and 458 women, ag…
Biological condition of adult migrants and nonmigrants in Wrocław, Poland
