BackgroundAn excess of weight including obesity have reached epidemic rates in all age
groups, both in developed and developing countries. It is notable that overweight
children and adolescents have a higher likelihood of becoming obese adults and to
present health-related problems early in life.ObjetivesTo verify associations of the lipid and hematological profiles with adiposity in
obese adolescents beginning multidisciplinary weight loss therapy.MethodsThis cross-sectional study was conducted with 85 adolescents of both genders, aged
12-19 years (Tanner staging 3 or 4) and body mass index greater than the
95th percentile. The sum of the triceps, subscapular and calf
skinfolds and the waist circumference were used to estimate adiposity. Blood
samples were collected from all patients after overnight fasting to analyze blood
lipids (total cholesterol, high-density lipoprotein, low-density lipoprotein, very
low-density lipoprotein and triglycerides), blood sugar and the hematological
profile (hemoglobin, platelets and red blood cells). The Kolmogorov-Smirnov test
and Spearman and Pearson correlation coefficients were used for statistical
analysis with significance set for p-values ≤ 0.05.ResultsThere were statistical differences between genders for red blood cells (p-value =
0.000), hemoglobin (p-value = 0.000) and platelets (p-value = 0.002). Positive
correlations were found for red blood cells (p-value = 0.031) and hemoglobin
(p-value = 0.024) with waist circumference. There was a negative correlation
between hemoglobin and the sum of skinfolds (p-value = 0.022).ConclusionThe results demonstrate an association between the lipid and hematological
profiles and body adiposity in obese adolescents thus reinforcing the importance
of treating obese adolescents early to prevent health related problems in adult
life.
Efeitos de diferentes intensidades de treinamento aeróbio sobre a composição corporal em adolescentes obesos Effects of different intensities of aerobic training on body composition in obese adolescents
Introdução: A ingestão alimentar constitui-se em uma das maiores barreiras para intervenções em adolescentes obesos. Objetivos: Analisar os efeitos da intervenção multidisciplinar sobre a ingestão alimentar de adolescentes obesos. Métodos: Este estudo caracteriza-se como pré-experimental e descritivo. A amostra foi composta por 33 adolescentes obesos, com idade entre 12 e 18 anos. Os adolescentes receberam intervenção nutricional, psicológica, clínica e física. Utilizou-se o registro alimentar de três dias e o valor energético total da dieta foi estimado por meio do software Nutwin (antes e após 12 semanas). Diferenças entre os momentos foram determinadas utilizando-se o teste “t” de Student para amostras dependentes. Resultados: A intervenção foi eficiente na redução da ingestão energética total (p=0,05), ingestão de lipídios (p=0,02), proteínas (p=0,01) e sódio (p=0,02). Conclusões: A intervenção multidisciplinar foi capaz de alterar os hábitos alimentares dos adolescentes, o que é essencial para a redução ponderal e manutenção da massa corporal.
