Prevalência e fatores associados ao tabagismo em estudantes de medicina de uma universidade em Passo Fundo (RS)

Abstract

Objective: To determine the prevalence of and factors associated with smoking among medical students, as well as to evaluate the profile of this group. Methods: A total of 316 medical students (98.7% of the total) at the University of Passo Fundo, in the city of Passo Fundo, Brazil, completed a self-report questionnaire with questions on tobacco intake and on attitudes related to smoking. In accordance with the World Health Organization guidelines, the students were classified as daily smokers, occasional smokers, former smokers or nonsmokers, those in the two first categories being considered active smokers. Results: We found that 16.5% of the students were active smokers (daily smokers, 5.4%; occasional smokers, 11.1%) and that 3.5% were former smokers. The mean age was 22.2 ± 2.4 years. Factors significantly associated with the smoking habit (p < 0.05) were male gender, paternal smoking, regular alcohol consumption and use of antidepressants or anxiolytics. For the majority (69.2%) of the smokers, the age at smoking onset was 15-19 years of age, and the main motivations to start smoking were selfinitiative and influence of friends. The conceptualization of smoking as an illness was significantly higher among the nonsmokers. In 70.6% of the smokers, tobacco intake was 1-10 cigarettes a day. Among the smokers, 92.3% agreed that smoking is harmful to health, 67.3% had tried to quit smoking, 96.0% believed themselves able to do so, and 87.2% intended to quit smoking. Conclusions: The prevalence of smoking remains significant among medical students. Therefore, it is fundamental that we develop more effective strategies for smoking prevention and cessation in order to reduce the number of smokers among future doctors.

Métodos: Responderam a um questionário autoaplicável, contendo perguntas sobre consumo e atitudes relacionadas ao tabagismo, 316 acadêmicos de medicina (98,7% do total) da Universidade de Passo Fundo. Segundo recomendações da Organização Mundial da Saúde, os estudantes foram classificados em fumantes diários, fumantes ocasionais, ex-fumantes ou não-fumantes, sendo considerados fumantes ativos os nas duas primeiras categorias. Resultados: Observou-se que 16,5% dos acadêmicos eram fumantes ativos (5,4% diários e 11,1% ocasionais) e 3,5% eram ex-fumantes. A média de idade foi 22,2 ± 2,4 anos. Os fatores significativamente associados ao tabagismo (p < 0,05) foram sexo masculino, pai fumante, uso regular de bebidas alcoólicas e uso de antidepressivos ou ansiolíticos. Verificou-se que 69,2% dos fumantes iniciaram o tabagismo entre 15 e 19 anos, tendo como principais motivações a vontade própria e/ou a influência de amigos. A conceituação do tabagismo como doença foi significativamente maior entre os não-fumantes. Quanto à carga tabágica, 70,6% dos fumantes consumiam 1-10 cigarros por dia. Entre os fumantes...

Prevalence of smoking among employees of a university hospital

“…The mean start age of tobacco consumption was approximately 18 years, similar to other studies that demonstrate that tobacco consumption starts during adolescence (18)(19)(20) . Despite health promotion and prevention campaigns that raise awareness on the harmful effects of cigarettes, it is known that, until today, tobacco is an instrument of curiosity and self-assertion among young people.…”

“…Other studies found similar results, appointing higher prevalence levels of smokers among professionals from other areas than among professionals graduated or working in the health area (16,19) . These may smoke less because they are more aware of the problems deriving from tobacco consumption than other professionals and/ or also because they have contact with patients with health problems associated with smoking, besides the severe restrictions on smoking in these environments.…”

Prevalence of and Factors Associated With Alcohol and Tobacco Consumption Among Physical Education Undergraduates

“…A study conducted with university students in Gurupi (TO), Brazil, showed that first cigarette use occurs around age 17 28 . In line with these results, a study performed at the medical school of Passo Fundo, Brazil, found that 69.2% of smokers started smoking between ages 15 and 19 years 29 . It is mistakenly believed that health sciences students are more aware of the harmful effects of alcohol and drugs.…”

Papel moderador do suporte do parceiro em fumantes e ex-fumantes

“…Temse verificado que intervenções familiares vêm se tornando uma prática comum, com resultados muito encorajadores (26) . Uma vez que um dos cônjuges inicia o tratamento, o outro que ainda fuma pode ser considerado uma ameaça, logo, seu papel é altamente decisivo como fonte de suporte (27) . Por exemplo, o suporte do parceiro se revelou como um moderador importante junto de mulheres com baixas habilitações literárias, história de depressão e em processo de desabituação tabágica, indicando que o sucesso diferia em função da presença de apoio do parceiro (28) .…”
