Background: Adiposity may play a role as a potential trigger for adrenarche. The purpose of this study was to evaluate the association between body mass index (BMI) and serum dehydroepiandrosterone sulfate (DHEAS) level. Methods:The medical records of 8-year-old girls who presented to our clinic between 2014 and 2016 with concerns regarding pubertal changes were retrospectively reviewed. The 192 girls were divided into two groups depending on activation of the hypothalamic-pituitary-gonadal (HPG) axis. Group I included 77 subjects with a breast Tanner stage 1 with unknown HPG axis or thelarche without activated HPG axis. Group II included 115 subjects with activated HPG axis. Serum DHEAS level ≥1.1 µmol/L was regarded as biochemical adrenarche. Results: Based on correlation analyses, BMI standard deviation score (SDS) was positively correlated with height SDS, bone age divided by chronological age (BA/CA), and DHEAS level in all subjects (r=0.269, r=0.270, r=0.298; all P<0.001, respectively). BMI SDS was negatively correlated with peak luteinizing hormone level in group II (r=-0.236, P=0.011). Based on multiple linear regression analyses, BMI SDS was associated with serum DHEAS level in all subjects (β=0.280, P<0.001), group I (β=0.415, P=0.001), and group II (β=0.206, P=0.030). DHEAS level was also associated with BA/CA in all subjects (β=0.402, P<0.001), group I (β=0.494, P<0.001), and group II (β=0.347, P<0.001). Conclusion: BMI SDS was associated with DHEAS level, which was associated with BA/CA. Childhood obesity may influence the development of adrenarche, which may contribute to advanced skeletal maturation.
This study attempted to investigate the perception of the technical qualification system for waxing. Waxing is one of the tasks done by aestheticians. For this study, a questionnaire was performed among aesthetic salon employees. A total of 220 copies were distributed, and 208 were used for the final analysis. Empirical analysis was performed to assess the significance level. For statistical analysis, validity, and reliability were analyzed, using SPSS WIN 21.0. Furthermore, descriptive statistics, cross-tabulation analysis, independent samples t-test, one-way ANOVA, and Duncan’s test were conducted, and the results found the following: For the perception of the national technical qualification system and waxing, a statistically significant difference was found. In the perception of the issuance of new national waxing licenses, no statistically significant difference was observed. When asked why such new national technical qualifications are needed, ‘an independent national waxing license is needed depending on the segmentation and the professionalization of waxing’ was the most common response. This study examined how aesthetic salon employees view waxing. It is anticipated that the study results would be used as basic data for studies on the issuance of new national waxing licenses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
