Equations based on anthropometric measurements for adipose tissue, body fat, or body density prediction in children and adolescents: a scoping review

Assessing the body composition of children and adolescents is important to monitor their health status. Anthropometric measurements are feasible and less-expensive than other techniques for body composition assessment. This study aimed to systematically map anthropometric equations to predict adipose tissue, body fat, or density in children and adolescents, and to analyze methodological aspects of the development of anthropometric equations using skinfolds. Methods: A scoping review was carried out following the PRISMA-ScR criteria. The search was carried out in eight databases. The methodological structure protocol of this scoping review was retrospectively registered in the Open Science Framework (https://osf.io/35uhc/). Results: We included 78 reports and 593 anthropometric equations. The samples consisted of healthy individuals, people with different diseases or disabilities, and athletes from different sports. Dual-energy X-ray absorptiometry (DXA) was the reference method most commonly used in developing equations. Triceps and subscapular skinfolds were the anthropometric measurements most frequently used as predictors in the equations. Age, stage of sexual maturation, and peak height velocity were used as complementary variables in the equations. Conclusion: Our scoping review identified equations proposed for children and adolescents with a great diversity of characteristics. In many of the reports, important methodological aspects were not addressed, a factor that may be associated with equation bias. Level IV: Evidence obtained from multiple time series analysis such as case studies. (NB: dramatic results in uncontrolled trials might also be regarded as this type of evidence).info:eu-repo/semantics/publishedVersio

A cross-sectional study of quality of life among Brazilian adults with type 1 diabetes treated with insulin glargine : findings and implications

We conducted a cross-sectional study with 401 patients of type 1 diabetes mellitus treated with insulin glargine in Minas Gerais, Brazil. Health-related quality of life (HRQoL) was assessed using EQ-5D-3L and the Diabetes Quality of Life Measure. Our findings showed that a worse HRQoL was associated with a low level of education, self-perceived health reported as poor/very poor, being bedridden and not physically exercised, had seen a doctor more than four times in the past year before the interview, and had reported comorbidities and episodes of hypoglycemia
