In archeology or forensics, the analysis of the ilia is often used to determine the age and sex of unknown individuals. However, sex determination using the skeletal remains of individuals who did not develop secondary sexual characteristics remains controversial. Accurately estimating the sex of subadults is hampered by a small number of studies based on identified skeletal collections of juvenile individuals. Here, we analyzed the sexual dimorphism of the subadult ilia using geometric morphometric techniques and individuals from the osteological collection of identified subadults from San José's graveyard (Granada). Seventy-one left ilia from 40 males and 31 females aged between birth and 1 year were included in the analysis. Three landmarks and 27 semi-landmarks of the ilia were placed. By principal component analysis, we found that the size and shape of the ilia could be used to differentiate males and females.

Parents play a key role in what their children eat. The Food Choice Questionnaire (FCQ) has been used elsewhere to assess the dietary motivations of parents of healthy children, but not for parents of children with chronic diseases such as type 1 diabetes (T1D). The aim of our research was to evaluate the associations between parental food choice motivations and the nutritional status and glycemic control of children with T1D. A cross-sectional observational study of children aged 5 to 16 years with T1D attending the Pediatric Endocrinology Unit of Puerta del Mar University Hospital in Cádiz (Spain) was performed. Demographic, anthropometric and clinical data, including glycated hemoglobin, were collected. The FCQ in Spanish was conducted to assess the eating behaviors of the main caregivers of children with T1D. Significance was established at the level of p-value < 0.05. In total, 85 children with T1D (female 56.5%, age 12.07 ± 2.93 years, HbA1c 7.29 ± 0.77%) were recruited. Of these children, 31.3% showed HbA1c levels of <7.0% and 44.9% had a TIR >70%. A significant positive correlation was found between Hb1Ac and “familiarity” (R: +0.233). Anthropometric measures (weight, BMI, skinfolds and body circumferences) showed significant positive correlations with “sensory appeal” and “price”. Parents’ eating behaviors influence the nutritional status of their children with T1D and their glycemic control of the disease.
