Mandibular shape analysis in fossil hominins
Body Mass Index of Married Bangladeshi Women
Body mass index (BMI) is a good indicator of nutritional status in a population. In underdeveloped countries like Bangladesh, this indicator provides a method that can assist intervention to help eradicate many preventable diseases. This study aimed to report on changes in the BMI of married Bangladeshi women who were born in the past three decades and its association with socio-demographic factors. Data for 10,115 married and currently non-pregn…
Influence of anthropometric measures and socio-demographic factors on menstrual pain and irregular menstrual cycles among university students in Bangladesh
Menstrual disturbances generally affect the daily activities of young females. The aim of this study was to determine the effects of anthropometric measures and sociodemographic factors on menstrual disturbances among university students in Bangladesh. Data were collected from 995 students from Rajshahi University using a stratified sampling technique between July 2004 and May 2005. Factors influencing menstrual pain and irregular menstrual cycle…
Age at Menarche of University Students in Bangladesh
Age at menarche has been shown to be an important indicator for diseases such as breast cancer and ischaemic heart disease. The aim of the present study was to document secular trends in age at menarche and their association with anthropometric measures and socio-demographic factors in university students in Bangladesh. Data were collected from 995 students from Rajshahi University using a stratified sampling technique between July 2004 and May 2…

Effect of craniofacial measures on the cephalic index of Japanese adult female students
This study was designed to identify possible craniofacial measurements that have an influence on the cephalic index (CI) of Japanese adult females. The total sample used in the current study consisted of 832 healthy Japanese adults. The subjects were all of Japanese birth and ancestry. The age range of the subjects was between 18–25 years. Eight craniofacial measurements were taken: head length, head breadth, head height, head circumference, mini…
Sexual dimorphism using elliptical Fourier analysis
The assessment of sexual dimorphism plays an essential role in numerous disciplines such as: (1) forensics, with its concern with skeletal identification, including sexing; (2) archeology, where the sexing of skeletal materials is an essential aspect; (3) primatology, where sex differences are diverse; (4) paleoanthropology, where the identification of sex can influence taxonomic and phylogenetic decisions, and (5) growth and development, where o…
Secular changes in head dimensions of Japanese adult male students over eight decades
Sexual dimorphism in the Japanese cranial base
An approach, computational shape analysis (CSA), is presented here which utilizes a Fourier‐wavelet representation to numerically describe shape features of biological forms. Two elements are involved: 1) elliptical Fourier functions (EFFs), to provide estimates of global aspects , and 2) continuous wavelet transforms (CWTs) to generate an objective estimate of localized features . EFFs are computed, using a set of pseudohomologous points, to cre…
A Fourier-wavelet representation of 2-D shapes
We present a new approach called computational shape analysis, which utilizes a Fourier-wavelet representation for characterizing shape features of 2-D forms commonly encountered in a wide set of sub-disciplines within the biological sciences. The morphology of interest consists of the human cranial base (CB) as depicted on lateral cephalometric radiographs. Given a complex irregularly bounded form in Cartesian coordinate space, we first compute …
Secular changes in head dimensions of Japanese females over eight decades
The aim of this work is to document secular changes in the head dimensions of Japanese adult females. The data set of the current study was compared with two others, one covering 1910–1917 and the other 1975–1979. The subjects of the present study were all of Japanese birth and ancestry, and were aged 18–25 years. Four head dimensions were measured: head length, head breadth, head height, and head circumference. The subjects’ height and body weig…
Adolescent growth events in eight decades of Japanese cohort data
The presence of secular trends in sex differences for the onset or takeoff of the adolescent growth spurt and subsequent (adolescent) growth of Japanese boys and girls were investigated using data published in “The Statistical Report of the School Health Survey” of the Ministry of Education, Science, Sports and Culture, Japan. An optimum kernel regression method was used to derive the biological parameters of the adolescent growth curve. The six …

Secular trends for takeoff and maximum adolescent growth for eight decades of Japanese cohort data
The presence of secular trends in the onset or takeoff of the adolescent growth spurt and subsequent adolescent growth of Japanese boys and girls were investigated using data published in "The Statistical Report of the School Health Survey" by the Ministry of Education, Science, Sports and Culture, Japan. An optimum kernel regression method was used to derive the biological parameters of the adolescent growth curve. An increasing trend in height …
Longitudinal study of cranial base shape changes in Macaca nemestrina
The primate cranial base (CB) represents a complex irregular structure even when limited to two dimensions, making it difficult to describe quantitatively using the conventional metrical approach composed of angles and distances. Consequently, a curve‐fitting procedure, elliptical Fourier functions (EFF), was utilized; which accurately defines the form of complex two‐dimensional morphologies. A longitudinal Macaca nemestrina sample consisting of …
Method for analyzing complex two‐dimensional forms
A generalized procedure, elliptical Fourier analysis, for accurately characterizing the shape of complex morphological forms of the type commonly encountered in the biological sciences, is described. Elliptical Fourier functions are derived as a parametric formulation from conventional Fourier analysis, i.e., as a pair of equations that are functions of a third variable. The use of elliptical Fourier functions circumvents three restrictions that …
Size and shape of the hominoid distal femur
A quantitative description of the shape of the distal femur is provided by Fourier analysis. Fourier analysis also facilitates the separation of the size and shape components which allows the removal of the distorting effect of size. Hence, comparisons between the hominoid groups can be based solely on shape. A sample of 91 hominoid distal femora from the Cleveland Museum of Natural History was used to make comparisons based on size and shape as …
