Age and pelvic dimensions are also analysed as potential contributing factors. The group under study, derived from the SIMON identified skeletal collection (Vaud, Switzerland), comprises individuals living at the end of the 19^th and in the first half of the 20^th centuries. The sample consists of 504 coxal bones (including 236 pairs) from 268 individuals (133 females and 135 males), aged 16 to 81, with age classes equally represented. The obstetric history is known for a subgroup of 99 females. Using the three visual criteria employed together, the results of sex estimation indicate that both the indeterminate rate (11.3% for observer 1 and 7.7% for observer 2) and the classification error rate (2.2% and 9.2%, respectively) are low. The study then shows that the preauricular groove, as defined by Bruzek (2002), is present in significant proportions in both nulliparous females (73.8%) and females who have given birth (79.8%), and that therefore it cannot be considered an indicator of obstetric history. The number of children does not seem to be an explanatory factor, but age contributes to the shaping of these bony imprints. The preauricular groove is already recognizable in close to 60% of females aged 16 to 39 years, but the bony changes are more marked with increasing age, leading to a decrease in both sex diagnostic error and indeterminacy. Correlation between a hyperfeminine morphology of the pelvis and a highly feminine development of the preauricular area may indicate a biomechanical contribution.</p>","PeriodicalId":46008,"journal":{"name":"Anthropologischer Anzeiger","volume":"79 2","pages":"169-182"},"PeriodicalIF":0.5,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39610460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the beginning of the 20^th century, the \"<i>sulcus praeauricularis\"</i> has been confused with the \"<i>sulcus paraglenoidalis\"</i> without a satisfactory explanation of their aetiology. Any groove in the preauricular area of the pelvic bone has been referred to as an indicator of female sex and used in sex estimation in a way that does not respect the nature of sex differences. Novotný (1979) included bone structures, which were described by various authors in both females and males, in his method of holistic evaluation. He proposed a three-step categorization for the evaluation of the bone surface of the pelvic preauricular area (three sub-characteristics scored independently) in order to distinguish the <i>sulcus praeauricularis</i> as a female trait from other structures that may occur in both sexes. However, Novotný's work did not become widely known. Testing of the Novotný method was performed in four groups of individuals of known sex without knowledge of the reproductive history of the females (Novotný 1981; Bruzek 2002; Mikešová 2008) and included a total of 852 pelvic bones (457 male and 395 female). The results showed that female morphology, which is characterized by the presence of various forms of <i>sulcus praeauricularis</i>, occurred in a total of 270 of 395 females (68.3%). Female morphology was found in only 5 of 457 males (1.1%). Male morphology was observed in 419 of 457 males (91.7%), but also in 11.1% of females (44 of 395). Indeterminate or ambiguous morphology was found in 33 of 457 males (7.2%) and 81 of 395 females (20.5%). The application of the Novotný method showed that of the total 275 specimens with female morphology, 98.2% were females and only 1.8% were males. It is therefore appropriate to use this reliable method to estimate the sex of skeletal samples.

However, reported sexual classification accuracies based on the sacrum produce highly discrepant estimates ranging from 54% to 98% depending on the method and reference sample. Here, we therefore aim to evaluate the sacrum's efficacy in differentiating males from females by comparing three different approaches in a homogeneous Central European sample (n = 58, 27 males and 31 females) obtained from the 19th century Weisbach collection. Specifically, we investigated the sacrum by 1) a qualitative visual inspection, 2) traditional linear metrics, namely, sacral width, corpus width, and the associated corporo-basal index, and 3) geometric morphometrics (GM) using a 3D configuration of 100 landmarks and semilandmarks. Classification accuracies for the qualitative approach ranged from 69% to 81%. The investigated quantitative methods based on linear dimensions led to comparable classification accuracies of 62% for sacral width and 78% for the corporo-basal index. However, absolute corpus width had a stronger discriminative power (86%), similar to the PC scores from shape space (87%). Unexpectedly, the GM approach, which considered the shape of the entire sacrum, did not classify better than linear variables. This was exceeded only when sacrum shape was combined with corpus width or another measure of size, like the natural logarithm of the centroid size, yielding a classification accuracy of 95%. The male and female group means differed mainly in the general height-to-width relationship and corpus-to-alae proportions, corroborating patterns previously described in the literature. Our results suggest that the sacrum is markedly less effective than the hipbone for sex determination, which is at odds with its central position within the pelvic girdle and thus its supposed obstetric relevance.</p>","PeriodicalId":46008,"journal":{"name":"Anthropologischer Anzeiger","volume":"79 2","pages":"211-220"},"PeriodicalIF":0.5,"publicationDate":"2022-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39610463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study uses a larger sample of 221 females and 204 males to identify a subsample of females and males matched for femoral length, femoral head diameter, and clavicular length (25 females, 46 males). For five measures of the pelvic inlet, the human sample with control of body size is compared with three primate species that are sexually monomorphic in body size and give birth to newborns with higher relative body masses than those of humans: <i>Aotus azarae</i> (15 females, 19 males), <i>Hylobates lar</i> (29 females, 29 males), and <i>Saguinus geoffroyi</i> (28 females, 30 males).

Humans have higher sexual size dimorphism of inlet circumference despite lower relative newborn body mass compared to the other species because human newborns are of larger body mass than predicted for an anthropoid with our adult female body mass.

Weight status was classified using International Obesity Task Force (IOTF) criteria. The sample was partitioned into three age groups (7-9, 10-12, 13-15 years) for analysis of secular change in the BMI using sex-specific analysis of covariance (ANCOVA) with age and age² as covariates, and for comparison of the prevalence of mild, moderate and severe thinness and of overweight and obesity. BMIs increased, on average, across the four surveys, but differences between adjacent surveys varied. Prevalence of severe and moderate thinness was low in both sexes, while mild thinness tended to decline over time, more so among girls. Overweight and obesity increased over time, especially in 2006 and 2016 compared to 1986 and 1996. In conclusion, secular changes in the BMI between 1986 and 2016 were significant.
