Uma hipótese para explicar algumas desordens periféricas vestibulares seria sua correlação com variáveis do estilo de vida. Assim, a realização de estudos populacionais sobre o tema em adultos jovens é relevante. OBJETIVOS: Analisar a prevalência de indicação de alterações no equilíbrio dinâmico em adultos jovens e sua possível associação com variáveis do estilo de vida, saúde e estados emocionais negativos (pois podem intervir nos resultados). MATERIAL E MÉTODO: Foi realizado um estudo epidemiológico transversal, não-probabilístico, retrospectivo-clínico, em adultos jovens (18-32 anos) de uma comunidade universitária com 751 indivíduos, com média de 22.45± 3.32 anos. Variáveis do estilo de vida, saúde e estados emocionais negativos (EEN), que são depressão, ansiedade e estresse, foram coletadas via entrevista. Teste de Unterberger foi aplicado para averiguar indicação de alteração no equilíbrio dinâmico. Indivíduos com equilíbrio dinâmico alterado (EDA) foram então comparados com os sem alteração (controle). RESULTADOS: Da amostra 642 (83.6%) desviaram menos que 45º enquanto que 109 (14.2%) apresentaram um desvio maior que 45º sendo então considerados o grupo EDA. O grupo EDA apresentou maior prevalência de tabagismo, abuso/dependência de álcool, hipertensão arterial sistêmica e de EEN. CONCLUSÃO: O estudo destaca a ocorrência de EDA que precisa ser comprovado em estudos futurosA one hypothesis to explain some vestibular peripheral disorders is their association with life style. Thus, studies with young adults are relevant. AIM: to analyze the prevalence of dynamic balance alterations in young adults and their possible association with life style variables, health and negative emotional states (since they can impact the outcome). MATERIALS AND METHODS: we carried out a non-probabilistic cross-sectional, clinical-retrospective study with young adults (18-32 years of age) from a university with 751 individuals, with a mean age of 22.45± 3.32 years. Life style, health and negative emotional states (NES) variables - depression, stress and anxiety, were collected by means of an interview. The Unterberger test was used in order to check for indications of dynamic balance alterations. Individuals with altered dynamic balance (ADB) were compared to those without these alterations (controls). RESULTS: From our sample, 642 (83.6%) had less than 45º of deviation, while 109 (14.2%) had greater than 45º deviation and were the considered with ADB. The ADB group had a greater prevalence of smoking, alcohol abuse/dependence, high blood pressure and NES. CONCLUSION: the study highlights the occurrence of ADB which needs to be corroborated in future studies

CONTEXT AND OBJECTIVES: Despite the decline in the prevalence of tobacco use in many countries, including Brazil, there are growing numbers of smokers who continue to smoke at a low daily rate, or less frequently (non-daily smokers). This group needs to be better characterized in order to direct preventive actions and public health policies. The aim here was to compare lifestyle, health characteristics and alcoholism problems among young adult smokers, non-daily smokers and non-smokers. DESIGN AND SETTING: This was a cross-sectional study in which volunteers from the university community and its surrounds in Santa Maria, State of Rio Grande do Sul, Brazil, were included between October 2007 and January 2008. METHODS: Out of 1240 volunteers initially contacted in a university cafeteria, a total of 728 participants of mean age 22.45 ± 3.32 years were selected for final analysis. Data were collected using structured questionnaires. RESULTS: In general, it was observed that the non-daily smokers showed intermediate characteristics in relation to the smokers and non-smokers. However, there was a significant association between non-daily smoking and alcohol abuse. The non-daily smokers presented an odds ratio of 2.4 (95% confidence interval: 1.10-5.48) in relation to the daily smokers and an odds ratio of 3.3 (confidence interval: 1.7-6.5) in relation to the non-smokers, with regard to presenting a positive CAGE test, thereby indicating alcohol abuse or dependence. CONCLUSION: The study suggested that non-daily smoking and alcohol consumption were concomitant behaviors.
