Secular Trend and Socioeconomic Variation in Body Height of Young Polish Men Between 1965 and 2023
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
Age at Menarche Is Associated With Leg‐Length Components Among the Adolescent Girls in West Bengal, India
BACKGROUND: The relationship between early age at menarche (AAM) and body height (HT), including its different segments has not been extensively studied among non Western populations. Lengths of the lower (distal) part of the leg, such as knee HT (KH) and tibial length (TbL), are considered to be sensitive indicators of living conditions during early growth and development. Life history theory predicts that within a survival challenge the growth …

Design: This was a prospective follow up study with measurements at two time points with gap of f…
Is digit ratio (2D)
Human females demonstrate higher religiosity than men in populations. Digit ratio (2D:4D), being a putative indicator of prenatal testosterone, is associated in varying degrees with characters that show sexual dimorphism. A small number of studies have indicated that religiosity may be associated with the biological basis of sex differences in humans. The objective of the present study was to ascertain whether 2D:4D in religiously oriented semina…

Estimating Growth in Height from Limited Longitudinal Growth Data Using Full-Curves Training Dataset
A variety of models are available for the estimation of parameters of the human growth curve. Several have been widely and successfully used with longitudinal data that are reasonably complete. On the other hand, the modeling of data for a limited number of observation points is problematic and requires the interpolation of the interval between points and often an extrapolation of the growth trajectory beyond the range of empirical limits (predic…
Nutritional and weight status of Indian mother‐child dyads experienced by a natural disaster
Natural disasters have detrimental effects not only on local infrastructure in an affected population but may also have an impact on the human biological condition, particularly during critical periods of life. This study aimed to assess the nutritional and weight status of women and their children who had experienced cyclone Aila prenatally and postnatally in comparison with a non-affected neighbouring group. The study sample involved N = 597 dy…

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…
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…
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

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.

In this analysis, a comparison is made between blood pressure of the Rarotonga, Cook Islands, population in 1996 with values obtained for this population in 1964. In addition, the extent to which education and occupation, as markers of modernization, associate with b…
The effect of the economic transition on the body mass index of conscripts in Poland
Secular change in height, sitting height and leg length in rural Oaxaca, southern Mexico
There are major secular increases in height, sitting height and estimated leg length of children and adolescents of both sexes since 1978. Secular gains in height are of similar magnitude in boys and girls 6-13 years, but are greater in adolescent and young adult males than females. The secular increase in height of young adults of both sexes is smaller than that among adolescents. Estimated leg length accounts for about 60% of the secular increa…
Changing Patterns of Social Variation in Stature in Poland
The aim of this analysis was to examine the effects on stature in two nationally representative samples of Polish 19-year-old conscripts of maternal and paternal education level, and of degree of urbanization, before and after the economic transition of 1990. Data were from two national surveys of 19-year-old Polish conscripts: 27,236 in 1986 and 28,151 in 2001. In addition to taking height measurements, each subject was asked about the socioecon…
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…
Relationship between early puberty and the risk of hypertension/overweight at age 50
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…
