RESUMOIntrodução: A prática regular de atividade física (PRAF) é fundamental em qualquer idade e tem sido considerada um meio de preservar e melhorar a saúde e a qualidade de vida do ser humano. A inatividade física é um importante fator de risco de doenças crônicas não transmissíveis, como diabetes e hipertensão arterial. Objetivo: Determinar a prevalência e os fatores associados à PRAF em adolescentes, adultos e idosos. Métodos: Estudo transversal, de base populacional, realizado no norte do estado de Minas Gerais, Brasil. Foi adotada amostragem por conglomerados em múltiplos estágios, cujos dados foram coletados por meio de um questionário em visitas domiciliares. A PRAF foi avaliada por meio da pergunta "Com que frequência você pratica atividade física?". Aqueles que responderam "sempre" ou "frequentemente" foram considerados ativos. Características sociodemográficas, comportamentais e de saúde geral foram avaliadas. Utilizou-se o teste do qui-quadrado e o modelo de regressão de Poisson, com ajuste robusto para as variâncias. Resultados: Entre os adolescentes, 45,2% foram considerados ativos. A PRAF entre adolescentes apresentou associação significativa com: menor idade, sexo masculino, aqueles que estavam estudando, que não fumavam e com maiores níveis de qualidade de vida/ domínio mental. Entre os adultos, 20,7% foram considerados ativos. A PRAF entre adultos apresentou associação significativa com sexo masculino, maior escolaridade e maior nível de qualidade de vida relacionado aos aspectos mentais. Entre os idosos, 19,1% foram considerados ativos. A PRAF entre idosos apresentou associação significativa com cor de pele autodeclarada branca, maior escolaridade, exercer atividade de trabalho e maior nível qualidade vida (aspecto mental). Conclusão: Observou-se um decréscimo do nível de atividade física com o aumento da idade cronológica. Recomenda-se a implantação de políticas públicas que estimulem a prática regular de atividade física nos subgrupos populacionais mais afetados pelo sedentarismo: os adultos e os idosos, especialmente as mulheres e os com menor nível socioeconômico.Palavras-chave: atividade física, prevalência, adolescente, adulto, idoso.

Physical inactivity is a major risk factor for chronic diseases

This study aimed to estimate the prevalence of impact of oral health conditions on physical and psychosocial dimensions among adolescents and to identify factors associated with severity of impact. The impact of oral health status was assessed by the instrument Oral Health Impact Profile (OHIP-14). The covariates were: socioeconomic status, habits and health care, use of dental services, and normative conditions of oral health. Structural equation modeling was performed, and 15.6% of adolescents reported impact in at least one dimension of the OHIP-14. The dimensions that showed the highest prevalence of impact were psychological distress (11.8%) and physical pain (6.6%). The number of teeth needing dental treatment, number of filled teeth, and CPI significantly affected severity of impact. In this adolescent population, unfavorable socioeconomic conditions were associated with reduced use of dental services, associated in turn with precarious oral health conditions and increased severity of impact.

OBJECTIVE To identify the factors associated with severity of malocclusion in a population of adolescents.METHODS In this cross-sectional population-based study, the sample size (n = 761) was calculated considering a prevalence of malocclusion of 50.0%, with a 95% confidence level and a 5.0% precision level. The study adopted correction for the effect of delineation (deff = 2), and a 20.0% increase to offset losses and refusals. Multistage probability cluster sampling was adopted. Trained and calibrated professionals performed the intraoral examinations and interviews in households. The dependent variable (severity of malocclusion) was assessed using the Dental Aesthetic Index (DAI). The independent variables were grouped into five blocks: demographic characteristics, socioeconomic condition, use of dental services, health-related behavior and oral health subjective conditions. The ordinal logistic regression model was used to identify the factors associated with severity of malocclusion.RESULTS We interviewed and examined 736 adolescents (91.5% response rate), 69.9% of whom showed no abnormalities or slight malocclusion. Defined malocclusion was observed in 17.8% of the adolescents, being severe or very severe in 12.6%, with pressing or essential need of orthodontic treatment. The probabilities of greater severity of malocclusion were higher among adolescents who self-reported as black, indigenous, pardo or yellow, with lower per capita income, having harmful oral habits, negative perception of their appearance and perception of social relationship affected by oral health.CONCLUSIONS Severe or very severe malocclusion was more prevalent among socially disadvantaged adolescents, with reported harmful habits and perception of compromised esthetics and social relationships. Given that malocclusion can interfere with the self-esteem of adolescents, it is essential to improve public policy for the inclusion of orthodontic treatment among health care provided to this segment of the population, particularly among those of lower socioeconomic status.
