RESUMO

OBJECTIVES: To analyze risk factors for overweight among adolescents grouped in three different socioeconomic levels. METHODS: This cross-sectional study included 1779 adolescents aged 11 to 17 years, grouped according to socioeconomic status (low, middle, and high). Parents reported their own anthropometric data and the adolescents had their anthropometric data taken by trained researchers, and completed three questionnaires. RESULTS: The prevalence of overweight was 16.7%, 23.8%, and 26.3% in low, middle and high socioeconomic status, respectively (P= 0.001). In all socioeconomic status, parent's overweight was associated with adolescent overweight (all P< 0.05). The students in both high (PR= 1.90) and middle socioeconomic status (PR= 2.00) from private schools were associated with overweight, and the students from low socioeconomic level to sedentary behavior (PR= 2.25) and high ingestion of fried food (PR= 2.35). CONCLUSION: In each socioeconomic status the overweight was associated with different risk factors in different ways, except for parents overweight.

OBJETIVO: Analisar os fatores de risco para o sobrepeso entre adolescentes agrupados em três níveis econômicos diferentes. MÉTODOS: Estudo transversal que incluiu 1779 adolescentes com idade de 11-17 anos, agrupados de acordo com a condição econômica (baixo, médio e alto). Os pais reportaram seus próprios dados antropométricos e os adolescentes tiveram seus dados antropométricos aferidos por avaliadores treinados, e também responderam a três questionários. RESULTADOS: A prevalência de sobrepeso foi de 16.7 por cento, 23.8 por cento e 26.3 por cento nas classes econonômicas baixa, média e alta, respectivamente (P=0.001). Em todas as condições econômicas, o sobrepeso dos pais foi associado com o sobrepeso dos filhos (P<0.05). Os estudantes de classes econômicas média e alta (RP=2.00) de escolas privadas foram associados com o sobrepeso, e estudantes de baixo nível sócio-econômico com comportamento sedentário (RP = 2,25) e alta ingestão de frituras (PR = 2.35). CONCLUSÃO: Em cada nível socioeconômico o sobrepeso é associado com diferentes fatores de risco de diferente formas, exceto para pais com sobrepeso.

RESUMO

BACKGROUND: The prevalence of dyslipidemia is increasing in many parts of Brazil, but it is yet unclear how much exercise is needed to attain beneficial effects on plasma lipoprotein levels. OBJECTIVE: The study analyzed eight cities of the state of São Paulo, the association between the continued practice of physical exercise throughout life and the occurrence of dyslipidemia in adulthood. METHODS: Cross-sectional study involving 2,720 adults, of both sexes, living in eight cities of the state of São Paulo. Through household interviews, the presence of dyslipidemia was self-reported and physical exercise practice was assessed in childhood (7-10 years), adolescence (11-17 years) and adulthood (leisure activities). In the statistical analysis, multivariate models were created using binary logistic regression. RESULTS: The prevalence of dyslipidemia was 12.2% (95%CI: 11.1% -13.5%) and there was no difference between cities (p = 0.443). Women (p = 0.001) and obese individuals (p = 0.001) had a higher rate of dyslipidemia. Current practice of physical exercise was not associated with the presence of dyslipidemia ([≥ 180 minutes per week] p = 0.165); however, physical exercise, both in childhood (p = 0.001) and adolescence (p = 0.001) was associated with a lower incidence of the disease. Physically active adults in all three stages of life were 65% less likely to report dyslipidemia (OR = 0.35 [0.15 to 0.78]). CONCLUSION: The continued practice of physical exercise throughout life was associated with a lower incidence of dyslipidemia in adults in the State of São Paulo.

RESUMO

O objetivo do estudo foi descrever a prevalência de sobrepeso e obesidade entre escolares da rede privada deensino do município de Presidente Prudente - SP. A amostra foi composta por 1215 jovens de ambos os sexos e idade entre 10 e 17 anos. Foram coletados valores referentes à massa corporal e estatura. Para indicação do estado nutricional, foi calculado o Índice de Massa Corporal e utilizada a tabela internacional de referência proposta por Cole et al.12. Os dados são apresentados em valores de média, desvio padrão e freqüência. Foram utilizados os testes Qui-quadrado e “t” de Student para comparação entre freqüências e médias, respectivamente. Valores de p inferiores a 5% foram considerados estatisticamente signifi cantes e todo o tratamento estatístico foi realizado no software específi co SPSS 10.0. Verifi cou-se que a prevalência de sobrepeso e obesidade foi de 35,7% para o sexo masculino, 20% para o feminino e 28,6% para aamostra total, sendo a prevalência no sexo masculino superior a observada no feminino (p = 0,001). Assim, conclui-seque os altos valores de sobrepeso e obesidade observados entre os escolares de Presidente Prudente, principalmente entre os indivíduos do sexo masculino, servem como forma de alerta e indicam a necessidade de intervenção por parte de profissionais da área da saúde em meio escolar

Nutritional status was identifi ed by means of Body Mass Index and the international table of reference values proposed by Cole et al.12 Dataare represented in the form of means, standard deviations and frequencies. The Chi-square test was used to comparefrequencies and Student’s t test was applied to and means. P values below 5% were considered statistically signifi cant and all statistical analysis were performed using SPSS 10.0 dedicated software. The observed prevalence rate of overweight and obesity was 35.7% for males, 20% for females (p = 0.001) and 28.6% for the whole sample. Therefore, this study concludes that the high overweight and obesity rates observed among students from the town of Presidente Prudente, particularly among the male sex, should be seen as a warning and indicate the need for interventions by health professionalin the school environment
