- The anthropometry in nutritional and growth assessment of children and adolescentsPublication . Sousa, BrunoFor nutritional and growth assessment, anthropometry plays an important role. Specific care for children and adolescents, described within this work, is needed in order to allow a correct evaluation of the situation. Due to the stage of growth and development of the child and adolescent population, an adequate choice of anthropometric variables, accuracy in measurement, and comparison with appropriate references that reflect the population or individuals to be evaluated are required. Anthropometry thus plays an important role in the daily clinical practice of the various professionals who evaluate the growth and nutritional status of children and adolescents, but it needs to be correctly used and interpreted.
- Waist circumference percentile in children from municipalities of developed and developing countriesPublication . Andaki, Alynne Christian Ribeiro; Mendes, Edmar Lacerda; Tinoco, Adelson Luiz Araújo; Santos, Amanda; Sousa, Bruno; Vale, Susana; Mota, JorgeAims: to design reference percentile curves of waist circumference (WC) in children aged 6–10 from municipalities of developed (Portugal) and developing (Brazil) countries and to compare these results with other international references. Methods: this cross-sectional study enrolled a 6–10-year-old probability sampling. Univariate analysis of covariance adjusted by height was carried out to test the main effects of age, sex, countries, and interactions. WC percentile curves were performed with the LMS Chart Maker. Results: The sample comprised 6,475 children. Portuguese children presented a curvilinear increase in WC curves and Brazilian WC curves have shown a linear increase with age both for boys and girls. Overweight and obesity prevalence was 15.9 % and 4.7 % for Portuguese children and 12.9 % 4.5% for Brazilian children, respectively. There was a main effect (p<0.0001) for age and countries, and an interaction effect for sex*age (p=0.001) and countries*age (p<0.0001). Portuguese boys and girls have shown higher values for the 50th, 75th, and 95th percentiles than Brazilian boys and girls. Conclusions: WC reference percentile curves were drawn for 6–10-year-old Portuguese and Brazilian children. Portuguese children have higher WC values than Brazilian children and other children from developed countries.
- Anthropometric assessment of children aged between 6 and 14 years from a school in LisbonPublication . Costa, Adriana; Ferreira-Pêgo, Cíntia; Sousa, BrunoAs a global epidemic, obesity is currently a significant public health challenge, especially in children. Childhood obesity is related to short term consequences, but also with an increased risk to develop many comorbidities in adult life, such as cardiovascular diseases, type 2 diabetes, strokes, and others. A cross-sectional study to assess the prevalence of normal weight, pre-obesity and obesity in school-aged children was designed. The final sample size analyzed included 81 participants (47 boys and 34 girls) aged between 6 and 14 years old. Pre-obesity and obesity were determined according to the BMI cut-off points adopted by the IOTF. Although no significant differences were found, the prevalence of pre-obesity and obesity for the total population studied was 16.00% and 6.20%, respectively, with 14.60%, and 4.30% for boys and 17.60% and 8.80% for girls. More girls were pre-obese and obese than boys except at ages 9 and 12. The same age that boys presented cardiometabolic risk associated with a WHtR>0.50. These results emphasize the importance of nutritional status assessment to develop appropriate actions to prevent childhood obesity.
