Lifestyle of college students: follow-up study during the first two years of the undergraduate

Introduction: The lifestyle (LS) have been constituted as a going concern factor in today’s society, since low levels of health and well -being may lead to adverse consequences , especially in vulnerable groups such as college students, whose behavior acquired at this stage can be extended to other stages of life. Model of the study: Cohort study. Objectives: This study aimed to evaluate the lifestyle of college students during the first two years of the undergraduate program. Methods: The study enrolled, students who enrolled in undergraduate programs of Teacher Education Center of the Federal University of Bahia Reconcavo in the first half of the school year 2010. The lifestyle was determined by using the selfadministered questionnaire “Style life Fantastic”. We used the Chi-square test, McNemar test and relative risk (RR), considering p<0.05. The sample that participated in the entire follow-up period was composed of 92 students (64.1% female). Results: There was an increasing trend in the prevalence of students who had unhealthy global LS (16.3% vs. 21.7%). Students who have already entered with LS unhealthy for the domains “Family and Friends” (RR=2.17; 95%CI: 1.25-3.76) and “introspection” (RR=1.69; 95%CI: 1.02-2.81) were at higher risk to remain with this behavior at the end of the second year of the degree course. Conclusions: Analyzing these results, together with the other findings of this study, it is concluded that the time spent in graduate influenced the LS students studied. Thus, it is suggested that public policies for health promotion are developed within the university campuses in order to contribute to the adoption of healthier behaviors among their studentsIntrodução: O estilo de vida (EV) têm se constituído como fator de constante preocupação na sociedade atual, uma vez que baixos níveis de saúde e bem-estar podem provocar consequências negativas, ainda mais em grupos vulneráveis, como estudantes universitários, cujas condutas adquiridas nesta fase podem se estender para outras etapas da vida. Modelo do estudo: Estudo de coorte. Objetivos: Avaliar o estilo de vida de estudantes universitários durante os dois primeiros anos do curso de graduação. Métodos: Participaram do estudo universitários que ingressaram nos cursos de graduação do Centro de Formação de Professores da Universidade Federal do Recôncavo da Bahia no primeiro semestre do ano letivo de 2010. O estilo de vida foi determinado através da utilização do questionário autoadministrado “Estilo de Vida Fantástico”. Utilizou-se o teste Qui-quadrado, teste de McNemar e risco relativo (RR), considerando p<0,05. A amostra que participou de todo o período de seguimento foi composta por 92 universitários (64,1% do sexo feminino). Resultados: Observou-se uma tendência de aumento na prevalência de universitários que apresentaram EV global pouco saudável (16,3% vs. 21,7%). Universitários que já ingressaram com EV pouco saudável para os domínios “Família e Amigos” (RR=2,17; IC95%: 1,25-3,76) e “Introspecção” (RR=1,69; IC95%: 1,02-2,81) tiveram maior risco para permanecer com este comportamento ao final do segundo ano do curso de graduação. Conclusões: O tempo de permanência na graduação teve influência sobre o EV dos universitários investigados. Políticas públicas de promoção da saúde devem ser desenvolvidas dentro dos campi universitários visando contribuir com a adoção de comportamentos mais saudáveis entre seus estudante

Skinfold reference curves and their use in predicting metabolic syndrome risk in children

Objectives: To draw skinfold (SF) reference curves (subscapular, suprailiac, biceps, triceps) and to determine SF cutoff points for predicting the risk of metabolic syndrome (MetS) in children aged 6–10 years old. Methods: This was a cross-sectional study with a random sample of 1480 children aged 6–10 years old, 52.2% females, from public and private schools located in the urban and rural areas of the municipality of Uberaba (MG). Anthropometry, blood pressure, and fasting blood samples were taken at school, following specific protocols. The LMS method was used to draw the reference curves and ROC curve analysis to determine the accuracy and cutoff points for the evaluated skinfolds. Results: The four SF evaluated (subscapular, suprailiac, biceps, and triceps) and their sum (∑4SF) were accurate in predicting MetS for both girls and boys. Additionally, cutoffs have been proposed and percentile curves (p5, p10, p25, p50, p75, p90, and p95) were outlined for the four SF and ∑4SF, for both genders. Conclusion: SF measurements were accurate in predicting metabolic syndrome in children aged 6–10 years old. Age- and gender-specific smoothed percentiles curves of SF provide a reference for the detection of risk for MetS in children. Resumo: Objetivos: Desenhar curvas de referência de quatro dobras cutâneas (subescapular, suprailíaca, bíceps, tríceps) e determinar pontos de corte para predizer o risco de SM em crianças de seis a 10 anos de idade. Métodos: Estudo epidemiológico de base populacional, corte transversal, com amostra probabilística, estratificada por segmento de ensino, com 1.480 crianças de 6 a 10 anos de idade, 52,2% do sexo feminino, oriundas de escolas públicas e privadas, localizadas na zona urbana e rural do município de Uberaba (MG). Antropometria (dobras cutâneas), pressão arterial e as coletas de sangue em jejum foram realizadas em espaço reservado na escola, seguindo protocolos específicos. O métodolo LMS foi utilizado para desenhar as curvas de referência e análise de curva ROC para determinar a acurácia e pontos de corte para as dobras cutâneas avaliadas. Resultados: As quatro DC avaliadas (subescapular, suprailíaca, bíceps e tríceps) e o seu somatório (∑4DC) foram acurados na predição da SM para meninas e meninos. Adicionalmente, pontos de corte foram propostos e curvas percentílicas (p5, p10, p25, p50, p75, p90 e p95) foram delineadas para as quatro DC e o ∑4DC, para ambos os sexos. Conclusão: Medidas de DC foram acuradas em predizer SM em escolares de seis a 10 anos de idade. As curvas percentílicas de DC desenhadas por idade e sexo fornecem referência na detecção do risco de SM em crianças.
