The aim was to study the influences of several background factors on age at marriage of ever-married females living in urban and rural areas of Bangladesh. Data was collected by Bangladesh Demographic and Health Survey (BDHS) in 2004.Chi-square test was performed to find the association between age at marriage and background factors of Bangladeshi females. Logistic regression analysis was used to identify the factors which were responsible for the age at marriage among ever-married females. Chi-square test demonstrated that age at marriage was positively associated (p<.01) with the level of female and her husband education for urban and rural. Muslim female showed lower probability in getting married at legal age (age of 18+ years) than that of non-Muslim and the probability was higher for rural areas. The results exhibited that only 7.4% of rural and about 14% of urban females got married at the age of 18+ years. Moreover, logistic regression analysis showed that husbands and their wife’s education, geographic regions, religion and watching TV were significantly effect on the age at marriage of Bangladeshi females.The results of this study provide some additional suggestive policy measures that the planners and implementers may consider for quality development of the inconsistent factors.

A systematic study of inbreeding effects on finger dermatoglyphic ridge counts among the Ansari Muslims in rural areas of Nandigram in West Bengal portrays some significant results. The distribution of total and absolute finger ridge counts (TFRC and AFRC respectively) show wide range of variation in inbred and non-inbred series of both the sexes. The rise of mean (studied both right and left sides combined as well as separately), increase of bilateral correlation and decline of bilateral asymmetry (examined both sides separately) of dermatoglyphic ridge counts in male and female samples due to inbreeding are observed. The study further records the sexual dimorphism in distribution and inbreeding effects on these traits. This investigation also attempts to throws some light on genetics of these traits. In frequency distributions, clear modes suggest that at least a few major genes (homozygous) clearly segregate on inbreeding with lowering of heterozygotes in antimodes. The results of the present study also conform to some earlier reports from different populations.

Overweight and obesity are the leading nutrition-related disorders of clinical and public health concern. Assessment and classification of these conditions are dependent on specific body mass index (BMI) cut-off points. A study of BMI with correlation to Cormic index (CI, sitting height /stature ratio), mid-arm circumference (MAC), waist circumference (WC) and lower limb length (LLL), was carried out on post-pubertal Nigerian subjects within Ilorin Metropolis. The subjects considered were randomly selected from some of the major converging centres within the metropolis. The height, weight, MAC waist circumference and lower limb length of 400 volunteers (200 males; 200 females) were measured. Their BMIs were calculated from the heights and body weights. The results obtained showed a mean BMI of 21.33 ± 0.328 and 21.83 ± 0.443 for the post-pubertal male and female population respectively. The mean MAC and waist circumference respectively were found to be 27.14 ± 0.380 and 77.80 ± 0.885 for the post-pubertal male population and 26.94 ± 0.376 and 75.44 ± 0.914 for the post-pubertal female population. The values obtained for the correlation coefficient (rXY) of the BMI to MAC and waist circumference were close to +1 for all the groups under study. This implies that there is a significant positive correlation between the BMIs and other parameters considered.

Variation is one of the most important phenomena occurring in humans, and is attributed to many factors such as mutation and natural selection. Many studies have emphasized the importance of anthropometric measurements as a means of studying variation in human populations as well as a veritable tool in forensic science for crime detection. This study investigates the nasal breadth, nasal length and nasal indices of individuals of Itsekiri and Urhobo ethnic extraction, as a baseline study which may be necessary for future reference in these regard. Nasal length and nasal breadth of 1000 living Itsekiri and Urhobo people, aged 25-45 years, were measured. From these data, nasal indices were calculated and results were compared with published standards for various world populations. The results showed that on the average, the Urhobos had a mean nasal index of 89.63 and the Itsekiri’s had a mean nasal index of 90.74. Sexual dimorphism was also observed in the ethnic groups studied with males having significantly higher nasal index values than the females (p < 0.05). Therefore, the two ethnic groups fall within the same nose type which is platyrrhine (short and broad nosed) expected of an African population. The findings of this study have confirmed anthropological differences amongst the two Nigerian ethnic groups examined.

Cephalometric techniques have been used by numerous researchers to produce standard mean values for skeletal, dental, and soft tissue structures. This has become useful in the classification of different populations. In the present study, 600 adult Igbo subjects (18-69yrs) comprising 300 males and 300 females were measured for facial height (FH) and nasal height (NH). The result obtained showed that on the average, the Facial Height (FH) of adult Igbo males was found to be 12.55 cm ± 2.11 cm while that of Adult Igbo females was found to be 11.19 cm ± 1.92cm.Futhermore, the Nasal Height (NH) for adult Igbo males was found to be 4.87 cm ± 0.84cm and 4.40 cm ± 0.76 for Adult Igbo Females. Statistical analysis of mean and Standard Deviation indicates sexual dimorphism, with significantly higher value (p 0.05) of all parameters in males compared to females. The result of this study will be of importance in functional orthodontics, clinical practice and forensic medicine.

The objective of this research work was to study the ischiopubic index in Cross River State in Nigeria. This was done by measuring the pubic and ischial lengths in 214-ray films (114 males and 100 females) of Cross River State indigenes. The ischiopubic index was calculated by dividing the pubic length by ischial length and by multiplying by 100.The sex differences of the pubic length, ischial length and ischiopubic index was found to be statistically significant when male and female x-ray films are compared (p<0.001).The demarking points of these parameters were worked out to determine sex. The demarking point of the ischiopubic index was more useful in sex determination assigning sex to 69% males and 81% females. The ischiopubic index therefore is a useful parameter in sexing of the hipbone. This research carried out in Departments of Radiology of the University of Calabar Teaching Hospital and the University of Calabar Medical Center There was no external funding for this research

Digital dermatoglyphics has been found useful in forensic medicine and identification purposes. It is useful in medical diagnosis of genetically inherited diseases and in detection of crimes. Anthropometric studies of the digit, palm and feet provides data that reveal the relative distribution of dermal ridges among people in different geographical zones. Cross-sectional study was carried out using 200 males and 200 females healthy volunteers of Annang ethnic group in Akwa Ibom State of Nigeria to establish their digital dermatoglyphic traits. This was done by counting and classifying their ridge pattern configurations of arches, loops and whorls. Ulnar loops were the most predominant digital pattern in females (50.1 percent) than in males (39.6 percent), followed by whorls (42.9 percent) in males, then arches (31.1 percent) in females and radial loop (2.1 percent) in males. The sex differences between these patterns were statistically significant (chi2 equal to 154.569; d.f

For an anthropologist, the prehistoric archaeological data would give an indication of the kind of data that we should be expecting today from the population. This data would inform us of the underlying physical and social complexity in the population as well as about inter-community relations. Ideally, we should be able to tell something about the archaeological past of each community. However, this is rarely, if ever, possible. Hence, only some broad outlines may be possible in this work to show these indications.

Three dimensional evaluation of internal structures of small bones with histological methods or conventional X-ray is difficult. Micro-computed tomography (µCT) can provide 3D datasets with high resolution. In this study we applied µCT to analyse tail vertebra of autotomizing lizards. Autotomy is an ability of several reptile families to loose their tail at predicted break points (autotomy plane) to escape from enemies. Until now, these autotomy planes have been described with histological and conventional radiographic methods only. Micro-CT produced high resolution (15 µm voxel size) images clearly showing the autotomy plane in the 3D reconstructions as well as in 2D slices. Micro-CT proved to be of high value for the examination of the 3D position of autotomy planes in tail vertebra of different reptile species. Therefore, µCT will also be useful for the evaluation of 3D bone microarchitecture in other biological research.

Therefore, µCT will also be useful for the evaluation of 3D bone microarchitecture in other biological research.","PeriodicalId":22525,"journal":{"name":"The Internet Journal of Biological Anthropology","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2007-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79638743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
