- Prevalence of at-risk drinking among Brazilian truck drivers and its interference on the performance of executive cognitive tasks(2016) OLIVEIRA, Lucio Garcia de; LEOPOLDO, Kae; GOUVEA, Marcela Julio Cesar; BARROSO, Lucia Pereira; GOUVEI, Paula Adriana Rodrigues; MUNOZ, Daniel Romero; LEYTON, VilmaBackground: Binge drinking (BD) has been associated with an increase in the risk of alcohol-related injuries. Alcohol continues to be the main substance consumed by truck drivers, a population of special concern, since they are often involved in traffic accidents. The aim of this study was to estimate the prevalence of BD and its interference in the executive functioning among truck drivers in Sao Paulo, Brazil. Methods: A non-probabilistic sample of 684 truck drivers was requested to answer a structured research instrument on their demographic data and alcohol use. They performed cognitive tests to assess their executive functioning and inventories about confounding variables. The participants were then divided according to their involvement in BD. Results: 17.5% of the interviewees have reported being engaged in BD. Binge drinkers showed a better performance on one test, despite having done so at the expense of more mistakes and lower accuracy. More interestingly, binge drinkers took three seconds longer than non-binge drinkers to inhibit an inadequate response, which is worrisome in the context of traffic. Overall, the deleterious effect of BD on performance remained after controlling for the effects of confounding variables in regression logistic models. Conclusions: As the use of alcohol among truck drivers may be as a way to get by with their work conditions, we believe that a negotiation between their work organization and public authorities would reduce such use, preventing negative interferences on truck drivers' cognitive functioning, which by its turn may also prevent traffic accidents.
- Driving under the influence of psychostimulant drugs: Effects on cognitive functioning among truck drivers in Brazil(2020) OLIVEIRA, Lucio Garcia de; BARROSO, Lucia Pereira; LEOPOLDO, Kae; GOUVEA, Marcela Julio Cesar; CASTALDELLI-MAIA, Joao; LEYTON, VilmaIntroduction: Brazil has one of the highest traffic accident rates in the world. Cargo vehicles are the second most common type of vehicle involved in these accidents. Driving under the influence of drugs increases the risk of truck drivers being involved in road traffic injuries or fatalities. Psychostimulant drug use among truck drivers is of particular interest, as they use these drugs to maintain their occupational performance. Aim: The aim of this study is to identify the prevalence of psychostimulant drug use among truck drivers through toxicological analyses of urine and saliva samples and to evaluate its effects on the drivers' performance on attention level and executive functioning tests. Methods: A nonprobabilistic sample of 684 truck drivers was recruited at truck stops along three highways in Sao Paulo, Brazil. Participants were requested to answer questions on personal information and work-related matters via a structured research instrument. Afterwards, they were asked to perform four cognitive tests and to complete other questionnaires on confounding variables. Strict exclusion criteria were enforced. Descriptive and inferential analyses were performed in the Minitab 18.1 and R programs, version 3.5.3. Then, the variables from the cognitive performance tests were included as response variables in the generalized linear regression models, separately, correcting for the effects from confounding variables. Results: 504 drivers were excluded from the data analysis due to health conditions that prevented them from safely participating in a cognitive performance evaluation. Therefore, 180 drivers remained in the sample; among them, 44 participants were categorized as users, and 136 were categorized as nonusers. The drug users performed better than the nonusers in almost all the cognitive tests in the univariate analysis. However, after controlling for the effects of confounding variables, we observed that despite drug users being faster at performing some tests, they committed more errors and had lower precision rates than nonusers in other measures. Moreover, users dealt with tasks that involved alternate and divided attention more poorly than nonusers. Conclusion: Psychostimulant drug use may initially seem advantageous to truck drivers since it allows users to maintain their attention for longer periods of time; however, the onus related to that use is much larger and should therefore be avoided by truck drivers and policed by competent authorities.
- Acidentes de trânsito envolvendo motoristas de caminhão no Estado de São Paulo: prevalência e preditores(2016) OLIVEIRA, Lucio Garcia de; ALMEIDA, Carlos Vinícius Dias de; BARROSO, Lucia Pereira; GOUVEA, Marcela Julio Cesar; MUñOZ, Daniel Romero; LEYTON, VilmaAbstract Abstract The mortality rate of traffic accidents (TA) is high in Brazil. Trucks are the second category of motor vehicles most often involved in TA. However, few studies have addressed the issue of TA among these professionals. The study aimed to estimate the prevalence of TA and their predictors in a sample of 684 truck drivers recruited in the state of São Paulo during 2012 and 2013. We requested participants to answer a research instrument on their personal and occupational data and their involvement in TA and traffic violations. A logistic regression model was developed to identify TA predictors. Almost 11% of the respondents suffered at least one TA in that timeframe. We identified the following TA predictors: having few years of experience as professional drivers (OR = 1.86; CI 95% = 1.05-3.38; p = 0.036); receiving some traffic tickets (OR = 1.91; CI 95% = 1.04-3.66; p = 0.043) and working more than 12 hours daily (OR = 1.84; CI 95% = 1.04-3.24; p = 0.034). Given those results, we suggest the development of a joint action among all the involved social stakeholders in order to negotiate truck drivers’ work organization aiming at reducing behaviors that may lead to traffic accidents.
- Use of alcohol and other drugs among Brazilian college students: effects of gender and age(2012) ANDRADE, Arthur Guerra de; DUARTE, Paulina do Carmo Arruda Vieira; BARROSO, Lucia Pereira; NISHIMURA, Raphael; ALBERGHINI, Denis Guilherme; OLIVEIRA, Lucio Garcia deObjective: To assess the frequency of drug use among Brazilian college students and its relationship to gender and age. Methods: A nationwide sample of 12,721 college students completed a questionnaire concerning the use of drugs and other behaviors. The Alcohol, Smoking and Substance Involvement Screening Test (ASSIST-WHO) criteria were used to assess were used to assess hazardous drug use. A multivariate logistic regression model tested the associations of ASSIST-WHO scores with gender and age. The same analyses were carried out to measure drug use in the last 30 days. Results: After controlling for other sociodemographic, academic and administrative variables, men were found to be more likely to use and engage in the hazardous use of anabolic androgenic steroids than women across all age ranges. Conversely, women older than 34 years of age were more likely to use and engage in the hazardous use of amphetamines. Conclusions: These findings are consistent with results that have been reported for the general Brazilian population. Therefore, these findings should be taken into consideration when developing strategies at the prevention of drug use and the early identification of drug abuse among college students.
- Occupational conditions and the risk of the use of amphetamines by truck drivers(2015) OLIVEIRA, Lucio Garcia de; SOUZA, Leticia Maria de Araujo de; BARROSO, Lucia Pereira; GOUVEA, Marcela Julio Cesar; ALMEIDA, Carlos Vinicius Dias de; MUNOZI, Daniel Romero; LEYTON, VilmaOBJECTIVE: To test whether the occupational conditions of professional truck drivers are associated with amphetamine use after demographic characteristics and ones regarding mental health and drug use are controlled for. METHODS: Cross-sectional study, with a non-probabilistic sample of 684 male truck drivers, which was collected in three highways in Sao Paulo between years 2012 and 2013. Demographic and occupational information was collected, as well as data on drug use and mental health (sleep quality, emotional stress, and psychiatric disorders). A logistic regression model was developed to identify factors associated with amphetamine use. Odds ratio (OR; 95% CI) was defined as the measure for association. The significance level was established as p < 0.05. RESULTS: The studied sample was found to have an average age of 36.7 (SD = 7.8) years, as well as low education (8.6 [SD = 2.3] years); 29.0% of drivers reported having used amphetamines within the twelve months prior to their interviews. After demographic and occupational variables had been controlled for, the factors which indicated amphetamine use among truck drivers were the following: being younger than 38 years (OR = 3.69), having spent less than nine years at school (OR = 1.76), being autonomous (OR = 1.65), working night shifts or irregular schedules (OR = 2.05), working over 12 hours daily (OR = 2.14), and drinking alcohol (OR = 1.74). CONCLUSIONS: Occupational aspects are closely related to amphetamine use among truck drivers, which reinforces the importance of closely following the application of law (Resting Act (""Lei do Descanso""); Law 12,619/2012) which regulates the workload and hours of those professionals. Our results show the need for increased strictness on the trade and prescription of amphetamines in Brazil.
- Drug use in college students: a 13-year trend(2012) WAGNER, Gabriela Arantes; OLIVEIRA, Lucio Garcia de; BARROSO, Lucia Pereira; NISHIMURA, Raphael; ISHIHARA, Luciana Morita; STEMPLIUK, Vladimir de Andrade; DUARTE, Paulina do Carmo Arruda Vieira; ANDRADE, Arthur Guerra deOBJECTIVE: To analyze drug use trends among college students in 1996, 2001 and 2009. METHODS: A cross-sectional epidemiological study with a multistage stratified cluster sample with 9,974 college students was conducted in the city of Sao Paulo, southeastern Brazil. An anonymous self-administered questionnaire was used to collect information on drug use assessed in lifetime, the preceding 12 months and the preceding 30 days. The Bonferroni correction was used for multiple comparisons of drug use rates between surveys. RESULTS: There were changes in the lifetime use of tobacco and some other drugs (hallucinogens [6.1% to 8.8%], amphetamines [4.6% to 8.7%], and tranquilizers [5.7% to 8.2%]) from 1996 to 2009. Differences in the use of other drugs over the 12 months preceding the survey were also seen: reduced use of inhalants [9.0% to 4.8%] and increased use of amphetamines [2.4% to 4.8%]. There was a reduction in alcohol [72.9% to 62.1%], tobacco [21.3% to 17.2%] and marijuana [15.0% to 11.5%] use and an increase in amphetamine use [1.9% to 3.3%] in the preceeding 30 days. CONCLUSIONS: Over the 13-year study period, there was an increase in lifetime use of tobacco, hallucinogens, amphetamines, and tranquilizers. There was an increase in amphetamine use and a reduction in alcohol use during the preceding 12 months. There was an increase in amphetamine use during the preceding 30 days.
