Height data of North Korean escapees are analyzed to assess changes in their biological standard of living. In contrast to the population of South Korea, as well as to that of most of the rest of the world, North Koreans did not experience an increase in physical stature during the second half of the 20th century. The divergence between the height of North- and South-Koreans began among the bir...

Spectral analysis of the physical stature of Americans and Europeans in the 18th and 19th centuries reveals a cyclical structure similar to the traditional view of the business cycle: a longer cycle with a length of 7-10 years, and a shorter cycle with a length of 3-5 years. The correlation between height cycles and cycles of economic variables such as grain prices indicates an influence of eco...

A major component of variation in body height is due to genetic differences, but environmental factors have a substantial contributory effect. In this study we aimed to analyse whether the genetic architecture of body height varies between affluent western societies. We analysed twin data from eight countries comprising 30,111 complete twin pairs by using the univariate genetic model of the Mx ...

Jumping and proprioception are important abilities in many sports. The efficiency of the proprioceptive system is indirectly related to jumps performed at specified heights. Therefore, this study recorded the ability of young athletes who play team sports to jump to a specific height compared with their maximum ability. A total of 154 male (age: 14.8 ± 0.9 years, body height: 181.8 ± 8.9 cm, bo...

The purpose of this study was to investigate the average tracheal length and number of the tracheal cartilages in Turkish people, with emphasis on the relationships to body height and sex. A hundred fresh human cadaver tracheas were harvested from 75 males and 25 females. Age, sex and body height of cadavers were recorded. All the neck and intrathoracic structures were removed. The tracheal len...

Pediatric cardiopulmonary resuscitation drug therapy is based upon body weight, a statistic that often requires estimation. Using two current techniques of estimating body weight and the devised weight-estimating method (DWEM), the authors estimated the weights of 258 children. The DWEM, which is based on body habitus and height, was more accurate than other methods (P less than 0.01). Using he...

background: adolescent pregnancy and childbirth are associated with increased risk and challenges for both mothers and birth outcomes. objective: to investigate the associations of growth change over time with parenting factors and to compare the differences between children born to adolescent and adult mothers in taiwan. materials and methods: the dataset retrieved from taiwan birth cohort stu...

Mussels are commonly used to monitor metal pollution despite high inter-individual variability in tissue concentrations. In this study, influences of body size, condition index and tidal height on concentrations of As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were investigated. Body weight was inversely related to metal concentrations and for Cd, Mn, Pb and Zn the regression was affected by tidal ...

1. Body-weight, body height, knee width, wrist width and skinfold measurements were made on males (n 139) and females (n 167) in three age-groups (20-22, 25-27 and 30-32 years). Percentage of body fat was calculated from skinfold thicknesses using regression equations according to Durnin & Womersley (1974). Three indices of relative weight were calculated: W/H2, W/Hp and W/W, where W is body-we...

The present study investigated attention bias in response to height-related words among young men in China. 47 [26 high height dissatisfied (HHD) and 21 low height dissatisfied (LHD)] men performed a dot-probe task. Eye movement (EM) recordings showed that compared to LHD men, HHD men had an avoidance bias in response to height-related words, which was revealed by less frequent first fixations ...
