Influência do estado nutricional pregresso sobre o desenvolvimento da síndrome metabólica em adultos

BACKGROUND The increase in the prevalence of excess weight among people of increasingly younger age groups may lead to the early development of cardiovascular risks. OBJECTIVE To investigate the prevalence of the metabolic syndrome among young adults and the impact of birth conditions and nutritional status during adolescence on this disorder. METHODS One hundred individuals were evaluated at three different stages of life. By consulting the database of people enlisted in the army reserve military service, data were collected on weight, height, and waist circumference of all draftees of 1996, 1997, and 1999 in order to analyze their nutritional status during adolescence. Using the same database, information was sought at the maternity on their birth conditions and the adult individuals were identified. Anthropometric and biochemical data were obtained from these adults. The Metabolic Syndrome (MS) was classified according to ATP III NCEP. Body fat percentage was assessed with bioelectrical impedance and the statistical analysis was performed using the Sigma Stat 2.0 software. RESULTS Prevalence of the MS was detected in 13% of the individuals. The birth conditions showed no relationship with the syndrome. In adolescence, those individuals diagnosed with MS had greater values for weight (11 kg; p =<0.001), WC (8 cm; p < 0.001), and BMI (2.5 kg/m(2); p= 0.002). CONCLUSION A significant part of the risk factors for cardiovascular conditions starts during childhood and adolescence, and is likely to persist throughout life; therefore, primary prevention measures are critical in the context of cardiovascular disease.FUNDAMENTO: O aumento da prevalencia do excesso de peso em faixas etarias cada vez mais jovens pode levar ao desenvolvimento precoce de fatores de riscos cardiovasculares. OBJETIVO: Investigar a prevalencia de sindrome metabolica em adultos jovens e a influencia das condicoes de nascimento e estado nutricional na adolescencia sobre este quadro. METODOS: Foram avaliados cem individuos, em tres fases da vida. A partir dos registros do banco de dados de alistamento do Tiro de Guerra, coletou-se peso, estatura e circunferencia da cintura de todos os alistados nos anos de 1996, 97 e 99, para analise do estado nutricional na adolescencia. A partir dos registros do mesmo banco, buscou-se informacoes sobre as condicoes de nascimento na maternidade e identificou-se os individuos, quando adultos. Na vida adulta, realizou-se avaliacao antropometrica e bioquimica. A classificacao da sindrome metabolica (SM) se deu de acordo com proposta do NCEP-ATP III. O percentual de gordura corporal foi aferido por bioimpedância eletrica. A pressao arterial foi aferida por aparelho automatico. A analise estatistica foi realizada no software Sigma Stat 2.0, p<0,05. RESULTADOS: Encontrou-se prevalencia de SM em 13% dos avaliados. As condicoes de nascimento nao apresentaram relacao com a determinacao na sindrome. Aqueles diagnosticados com SM apresentavam, na adolescencia valores superiores de peso (11 kg; p =<0,001), circunferencia da cintura (8 cm; p < 0,001) e indice de massa corporal (2,5 kg/m2; p= 0,002). CONCLUSAO: Grande parte dos fatores de risco cardiovasculares tem inicio na infância e adolescencia e tende persistir ao longo da vida, desta forma, medidas de prevencao primaria sao de grande importância no cenario das doencas cardiovasculares.

Anthropometry of Adolescents: Brazilian Perspectives

Health status of Brazilian adolescents is directly affected by huge inequalities, considering the social and economic conditions they are submitted to. According to a national survey, 10% of adolescents present height-for-age deficit. The analysis of the secular trend of the nutritional profile of the group under discussion emphasizes the drop in height deficit for 30 years, although the prevalence observed is still considerable. On the other hand, there is increased prevalence of excess weight and obesity. Adolescents are in full transformation and the chronological age not always means similarity among peers. Hence, in some studies of female adolescents, the methodology includes a 1-year period after menarche to have a homogeneous sample and assure that the typical changes of adolescence influence less in the results. This methodology also enables adolescents assessed by non-medical professionals to have more specific orientations according to their sexual maturation stage. Despite the fact this methodology assesses sexual maturation close to real situation, it is known that there are limitations, mainly in males and in females who had no menarche yet.
