RESUMO

Resumo Introdução As doenças crônicas não transmissíveis (DCNT) apresentam origem multifatorial e entre os fatores de risco predisponentes a elas estão os comportamentos relacionados ao estilo de vida. Esses comportamentos poucas vezes ocorrem de maneira isolada, sendo a simultaneidade um fator agravante para o desenvolvimento de DCNT. Objetivo Estimar a ocorrência simultânea de comportamentos de risco para saúde e fatores associados na população brasileira. Método Utilizaram-se dados da Pesquisa Nacional de Saúde realizada em 2013. Os comportamentos de risco foram: tabagismo, consumo abusivo de bebidas alcoólicas, consumo irregular de frutas, legumes e verduras, tempo excessivo de TV e inatividade física. A presença de cada comportamento foi somada para obter a simultaneidade. As variáveis independentes analisadas foram: sexo, faixa etária e nível de escolaridade. Utilizou-se o teste do qui-quadrado para avaliar os fatores associados à ocorrência simultânea e a regressão logística para a associação entre os comportamentos de risco à saúde avaliados. Resultados Os comportamentos de risco mais frequentes foram: inatividade física (68,5%), consumo irregular de frutas, legumes e verduras (32,9%) e tempo excessivo de TV (28,9%). Quatro em cada dez indivíduos estavam expostos a dois comportamentos de risco simultaneamente. A ocorrência de três ou mais comportamentos de risco foi mais frequente entre os homens adolescentes e adultos quando comparados aos idosos, e houve redução gradual da frequência com o aumento da escolaridade. Conclusão Foi elevada a frequência de ocorrência simultânea de comportamentos de risco para saúde, a qual pode comprometer as condições de saúde da população brasileira.

Abstract Background Chronic non-communicable diseases (NCDs) have a multifactorial origin and lifestyle-related behaviors are among the predisposing risk factors. These behaviors seldom occur in isolation, and the simultaneity is an aggravating factor for the development of NCDs. Objective To estimate the simultaneous occurrence of health risk behaviors and associated factors in the Brazilian population. Method Data from the National Health Survey conducted in 2013 were used. The risk behaviors evaluated were smoking, abusive alcoholic beverage consumption, irregular consumption of fruits and vegetables, excessive screen time, and physical inactivity. The presence of each behavior was added to obtain simultaneity. The independent variables analyzed were gender, age group, and education level. The chi-square test was used to assess factors associated with simultaneous occurrence and logistic regression for the association between the health risk behaviors assessed. Results The most frequent risk behaviors were physical inactivity (68.5%), irregular consumption of fruits and vegetables (32.9%), and excessive screen time (28.9%). Four out of ten individuals were exposed to two risk behaviors simultaneously. The occurrence of three or more risk behaviors was more frequent among males, adolescents, and adults, compared to the elderly, and there was a gradual reduction with the increase in the education level. Conclusion The frequency of simultaneous occurrence of health risk behaviors was elevated, which may compromise the health conditions of the Brazilian population.

RESUMO

Aim: To verify the association between insufficient level of physical activity and multiple health risk behaviors (HRB) in adolescents. Methods: This is an epidemiological study with cross-sectional design carried out in 2016 with 3,617 adolescents aged 14-19 years and enrolled in the public-school system of Sergipe, northeast Brazil. Data were collected using the Global School-based Student Health Survey (GSHS/WHO). The insufficient level of physical activity was defined as not achieving at least 60 minutes of moderate to vigorous physical activity for 5 days a week. The HRB analyzed were smoking, alcohol consumption, low fruit consumption and exposure to sedentary behavior. The analysis of prevalence odds ratio was used to identify the association between insufficient level of physical activity and HRB, as well as unadjusted and adjusted binary logistic regression for the association between socioeconomic and demographic variables. Results: The prevalence of insufficient level of physical activity was 83.3%. There was association between physical inactivity and low fruit consumption and alcohol consumption (p<0.001). Insufficient level of physical activity was also associated with female sex (OR=1.90, 95% CI, 1.56-2.32), family income of up to 2 minimum wages (OR=1.57, 95% CI, 1.17-2.11), maternal schooling less than 8 years (OR=1.55, 95% CI, 1.28-1.86) and exposure to two different HRB at the same time (OR=1.76, 95% CI, 1.27-2.45). Conclusion: The prevalence of insufficient level of physical activity is high and was associated with multiple HRBs in this understudied population. These findings may support interventions focusing on the cluster of risk behaviors in youth.(AU)

RESUMO

It is time for an expansion and enrichment of evolutionary theory. The "back to the future" proposal contained herein is based on three postulates: 1) Neo-Darwinism is too impoverished for this task; 2) its predecessor, Darwinism, contained the necessary breadth of vision and metaphor to be the basis for an inclusive and unifying theory of biology; and 3) the necessary framework for this new stage in the evolution of evolutionary theory is largely in place. We make our case through the use of a number of metaphorical dualisms designed to help focus discussions toward a more cooperative and productive approach to the study of living systems. Along the way, we suggest a number of self-induced paradoxes in neo-Darwinian accounts of evolution that are resolved by our perspective.
