Substance use and its predictors among undergraduate medical students of Addis Ababa University in Ethiopia

<p>Abstract</p> <p>Background</p> <p>Substance use remains high among Ethiopian youth and young adolescents particularly in high schools and colleges. The use of alcohol, <it>khat </it>and tobacco by college and university students can be harmful; leading to decreased academic performance, increased risk of contracting HIV and other sexually transmitted diseases. However, the magnitude of substance use and the factors associated with it has not been investigated among medical students in the country. This study was conducted to determine the prevalence of substance use and identify factors that influenced the behavior among undergraduate medical students of Addis Ababa University in Ethiopia.</p> <p>Methods</p> <p>A cross-sectional study using a pre-tested structured self-administered quantitative questionnaire was conducted in June 2009 among 622 medical students (Year I to Internship program) at the School of Medicine. The data were entered into Epi Info version 6.04d and analyzed using SPSS version 15 software program. Descriptive statistics were used for data summarization and presentation. Differences in proportions were compared for significance using Chi Square test, with significance level set at p < 0.05. Multivariate logistic regression analyses were used to assess the magnitude of associations between substance use and socio-demographic and behavioral correlates.</p> <p>Results</p> <p>In the last 12 months, alcohol was consumed by 22% (25% males vs. 14% females, p = 0.002) and <it>khat </it>use was reported by 7% (9% males vs. 1.5% females, p < 0.001) of the students. About 9% of the respondents (10.6% males vs. 4.6% females, p = 0.014) reported ever use of cigarette smoking, and 1.8% were found to be current smokers. Using multiple logistic regression models, being male was strongly associated with alcohol use in the last 12 months (adjusted OR = 2.14, 95% CI = 1.22-3.76). Students whose friends currently consume alcohol were more likely to consume alcohol (adjusted OR = 2.47, 95% CI = 1.50-4.08) and whose friends' use tobacco more likely to smoke (adjusted OR = 3.89, 95% CI = 1.83-8.30). <it>Khat </it>use within the past 12 months was strongly and positively associated with alcohol consumption (adjusted OR = 15.11, 95% CI = 4.24-53.91). Similarly, ever use of cigarette was also significantly associated with alcohol consumption (adjusted OR = 8.65, 95% CI = 3.48-21.50).</p> <p>Conclusions</p> <p>Concordant use of alcohol, <it>khat </it>and tobacco is observed and exposure to friends' use of substances is often implicated. Alcohol consumption or <it>khat </it>use has been significantly associated with tobacco use. While the findings of this study suggest that substance use among the medical students was not alarming, but its trend increased among students from Year I to Internship program. The university must be vigilant in monitoring and educating the students about the consequences of substance use.</p

Association between moment of the undergraduate course and cardiovascular risk factors in university students

AIM: This study aimed to verify the association between moment of the undergraduate course and cardiovascular risk factors in a representative sample of university students Methods: A total of 1,599 university students (1,197 freshmen and 402 seniors) were investigated for the following risk factors: insufficient practice of physical activity, tobacco and alcohol consumption, poor eating habits, excess body weight, increased waist circumference and elevated arterial pressure. Information regarding the practice of physical activity were obtained using the International Physical Activity Questionnaire (IPAQ) instrument, the behaviors using the Youth Risk Behavior Surveillance, and the socio-environmental information using the methodology of the Associa&#231;&#227;o Brasileira de Empresas de Pesquisa (Brazilian Association of Research Companies). RESULTS: A significantly higher probability of presenting the following risk factors was verified among the senior students: insufficient practice of physical activity, smoked, consumed alcohol or drank alcohol in excess within the last thirty days. CONCLUSION: The results suggest that students closer to the end of the undergraduate course show a higher possibility of presenting some cardiovascular risk factors than those just entering the university environment. Therefore, prevention programs and health promotion during the undergraduate course should be investigated

Tabagismo e consumo de álcool em estudantes universitários: prevalência e fatores associados Smoking and alcohol consumption among university students: prevalence and associated factors

O presente estudo teve o objetivo de verificar a prevalência de tabagismo e consumo de álcool entre estudantes da Universidade Federal de Pelotas (UFPel), além de investigar os fatores associados a esses comportamentos. A amostra foi composta por 485 alunos que ingressaram na UFPel em 2008. Os alunos foram selecionados de maneira aleatória entre cursos de todas as áreas da UFPel e responderam a um questionário pré-testado na sala de aula, sob supervisão da equipe de pesquisa. Dos indivíduos entrevistados, 53,9% eram do sexo feminino e 42,3% tinham menos de 20 anos. Em relação ao consumo de álcool, 75% da amostra o utilizam pelo menos uma vez por mês; a prevalência de risco para o alcoolismo foi de 6,2%. Em relação ao tabagismo, 10,2% dos estudantes relataram fumar regularmente ou nos fins-de-semana. Além disso, mais de 90% dos fumantes e dos que consomem bebidas alcoólicas iniciaram o hábito antes de ingressar na universidade. O tabagismo apresentou uma relação direta com a idade e inversa com a autopercepção de saúde. Em relação ao álcool, estudantes que moram com amigos relataram um maior consumo. Os dados sugerem a necessidade de intervenções no meio acadêmico. Entretanto, cabe destacar que as ações para a população adolescente como um todo devam ser priorizadas, pois mais de 90% dos alunos adquiriram os hábitos antes de ingressarem na universidade, demonstrando que o início do consumo está ocorrendo em idades mais precoces.<br>The study aimed to estimate the prevalence of smoking and alcohol intake among university students from the Federal University of Pelotas, Brazil (UFPel), as well as to investigate factors associated with both habits. The sample included 485 students who were admitted to the university in 2008. Students were sampled randomly across all schools of the UFPel campus, and answered a pre-tested questionnaire, which was administered in the classroom by a member of the research team. Of the individuals interviewed, 53.9% were females and 42.3% were under 20 years. Regarding alcohol intake, 75% used alcohol once a month or less frequently, and the prevalence of risk for abusive alcohol intake was 6.2%. Regarding smoking, 10.2% reported smoking regularly or on weekends. More than 90% of those who smoked or used alcohol started before entering the university. Smoking was directly related to age and inversely related to self-rated health. In terms of alcohol intake, those who lived with friends were more likely to use it. Our data suggest the need for implementing strategies to promote healthy lifestyles among university students. However, the fact that more than 90% of individuals started to smoke or drink before entering the university suggests that interventions should target adolescents as a whole, and not only those who are university students, because onset of smoking and alcohol intake seems to occur at earlier ages

Smoking among undergraduate students in the area of health Tabagismo entre acadêmicos da área de saúde

The aim of this study was to evaluate the relationship between smoking and socio-demographic and behavioral factors among undergraduate students in the area of health at the State University of Paraíba, Brazil. An analytical cross-sectional study was conducted with a representative sample from each of the following courses: Dentistry, Nursing, Psychology, Pharmacy, Physical Therapy and Physical Education. A total of 492 students were interviewed using a structured questionnaire. The chi-square and Fisher's Exact tests were used for statistical analysis at a 5% level of significance. Smoking prevalence was 5.7% and stress was the main reason for starting the habit (36.8%). In the multivariate analysis by logistic regression, the variables of gender, religious persuasion, semester attended in the course, and alcohol consumption were significantly associated with smoking (p<0.05). Although other studies reported a strong relationship between university students and smoking, the prevalence of smokers was low. Most of the variables studied revealed a correlation with smoking. Since smoking and alcohol consumption are the two major human addictions, this study suggests a bidirectional relationship between these variables.<br>Avaliar a relação entre o tabagismo e os fatores comportamentais e sociodemográficos entre acadêmicos da área de saúde da Universidade Estadual da Paraíba (UEPB). Foi realizado um estudo transversal analítico, no qual foi obtida uma amostra representativa de cada curso (Odontologia, Enfermagem, Psicologia, Farmácia, Fisioterapia e Educação Física). Foram entrevistados 492 alunos por meio de formulário estruturado. Os testes estatísticos utilizados foram Qui-quadrado e o Exato de Fisher (significância de 5%). A prevalência de tabagismo foi de 5,7% e o estresse foi a principal razão para o início do hábito (36,8%). Na análise multivariada por regressão logística as variáveis, sexo, prática de religião, período cursado e consumo etílico apresentaram-se associadas ao hábito de fumar (p<0,05). Apesar de estudos relatarem uma forte relação entre estudantes universitários e fumo, a prevalência de tabagismo foi baixa. A maioria das variáveis estudadas demonstrou associação com o hábito de fumar. Sendo o fumo e o álcool as duas maiores dependências humanas, este estudo sugere uma relação bidirecional entre estas variáveis
