Alcohol consumption impairs driving skills and responsible for a high proportion of traffic accidents. This research examined the effects of blood alcohol consumption (BAC) level on driver’s physiological behavior and driving performance under simulated driving environment. The participants consisted of eight healthy young male drivers with an average of eight years driving experience. The scenario considered was 5 min driving on a highway with different speed limits, crossings, and unexpected event. Results showed that statistically significantly decreased alpha and increased theta power frequency was observed with increased BAC level. Heart rate was statistically significantly elevated with increased BAC level. The accident rate and the over speed rate were significantly higher with higher BAC level. Alcohol intoxication affected drivers’ decision-making ability, vision and integrating visual information ability.

This study examines changes in alcohol consumption and its adverse effects in Poland from 1950 to 2005. First, we estimate the total alcohol demand function and test Becker and Murphy's (1988) rational addiction model. Next, we explore substitution effects between beer, wine, and spirits and report income and own- and cross-price elasticities of demand for beer, wine, and spirits. Finally, we examine some adverse effects of alcohol consumption: traffic accidents, suicide rates, and vandalism rates. In particular, the effect of lowering the blood alcohol level limit (BAC) on traffic accidents is estimated.

Abstract: Introduction: Alcoholism is the recent trend among college students. Peer pressure,stress,depression are some factors that drive these students to practice this social evil. Under intoxication,consequences are grave. Drunk and driving, road traffic accidents, legal issues, antisocial activities are some of them, that has proved alcoholism a public menace. Objective: To assess the risk factors and consequences of alcohol consumption among adolescents. Materials and Methods: A survey was carried out in the colleges under NITTE University. Students present at the day and time of visit were covered. A questionnaire was prepared comprising of a set of 14 questions covering the main objective of the survey. The students were asked to fill the questionnaire irrespective of their gender or whether they consume alcohol or not. Results: From the survey, we found that social gatherings and lifestyle adaptation are major factors that prompt students to consume alcohol. Peer pressure,stress and parents influence are other factors.The consequences observed are legal issues and family problems. But majority didn't seem to face any grave problems due to alcohol intoxication. Conclusions: According to our study, more than 55% of the subjects that consume alcohol do so due to peer pressure, academic stress and emotional stress. Also, more than quarter of those consuming alcohol are involved in road traffic accidents and other legal issues, as well as having familial problems.

Do So

Blood alcohol concentrations (BACs), interview data, and unobtrusive measures of driving performance were obtained on public highways at 42 rural sites. Special data acquisition and recording systems were developed to obtain analog records of speed and lateral position electronically. Interview results confirmed that young male motorists are an important population-at-risk, but older male and female liquor drinkers are also prevalent. A double standard exists regarding attitudes toward beer and liquor, especially among younger males. Driving performance measures indicated that drivers with .08–.149 BAC react with caution to unexpected situations, but are less able to smoothly come to a stop when directed to do so.

Common patterns of alcohol consumption are described with their main criteria, blood alcohol levels, and diagnostic criteria. Binge drinking, an acute alcohol intoxication pattern of particularly concern, is also described, as it appears to be the most common pattern among teenagers when the brain is not yet mature. A number of classification schemes have been proposed specially for social drinking and alcohol dependence, and discussions still surround about them. The article summarize a consensus in classification.

Sham Point

The effects of two different traditional acupuncture point combinations and a sham point were compared in 35 healthy volunteers 20 minutes and 2 hours after a single draught of 40% alcohol (1ml/kg body weight). Clinical measurement, using tests of equilibrium and orientation, and specific tests of the metabolism and elimination of alcohol, formed the basis of this comparison. The results are statistically significant (P<0.05). A needle in the sham point produced no measurable effect compared to the non acupuncture control. After both traditional acupuncture point combinations, observing all the measured parameters, the clinical effects of alcohol intoxication were minimised, while the alcohol level in the expired air was increased and the blood alcohol decreased.

Alcohol intoxication is usually associated with drowning, falls, overdoses, fires, occupational accidents, physical and sexual abusements, domestic violence and traffic accidents. Therefore, alcohol considered an important factor for the explanation of the occurrence of many types of injuries. For many purposes such as forensic, it is important to establish a detection method to ensure whether the subject or the patient have consumed alcohol at a level that would be the reason for the accidents or injuries occur. Therefore, in this work, a simple, rapid and low-cost method was developed and validated for the detection of the alcohol in saliva as a function of blood alcohol concentration (BAC). The method is based on fabricated a biosensor consisted of chromium oxide nanoparticles deposited on filter paper. The validation of the biosensor was tested on 50 participants which categories into two selected groups (1 and 2). Group 1 consisted of 20 subjects from an organized party (no alcohol), they usually consumed three to four drinks as an average per week while Group 2 consisted of 30 subjects from an organized party the local bar (alcohol group), usually consumed two to three drinks per day. The results of the present study have shown that 95% of group 1 demonstrated positive results with variable colour intensities of the BAC in comparison to the 80% only of subjects from group 2. The present study has approved that the fabricated biosensor can effectively detect 0.02% or more of BAC which can be a useful test for many purposes such as medical, forensic, research and workplace.

Overall Mortality

Alcohol consumption alters one’s consciousness and may lead to accidents and traumatic events with deadly consequences. We aimed to analyze the most recent information available in WHO databases about overall mortality rates and alcohol consumption in European countries. The parameters taken into account were the total number of deaths by trauma, alcohol consumption per capita, prevalence of heavy drinking episodes and national legal blood alcohol concentration while drinking The mortality rate by trauma is influenced by many factors and alcohol intoxication could be one of them. Our analysis shows a moderate correlation between overall alchool consumption and death by trauma in Europe in 2015. There are studies who show a positive effect of alcohol consmption on the overall chance of survival after trauma. Chronic consumption is associated with an increase in mortality. Nonetheless, further research is needed and strongly encouraged.

Background: Road traffic accidents are a significant cause of morbidity and mortality worldwide and a major cause of sudden deaths in Sri Lanka.Methods: This study was conducted to assess risk factors for RTAs using 360 injured drivers, admitted to the accident wards in two teaching hospitals in Kandy and Kurunegala using interviewer-administered questionnaires.Results: The majority of the study population (97%) was male and most drivers were 26-35 years of age. Motorcycles were the most common vehicle (79%) involved in RTAs and 47% of drivers had a driving experience of less than 10 years. The driving speed of 31-45 km/ h was reported in one-third of the RTAs and 76.9% of RTAs occurred on carpet roads mostly on Wednesdays and Fridays. Only 29 (8.055%) vehicles reported technical problems at the time of the RTA. There is a significant association (p<0.001) between the speed of the vehicle and the driving experience and the type of the vehicle and the age of the participants. There is an association between the type of the vehicle and the site of injury of drivers and between the speed of the vehicle and the usage of alcohol (P<0.01).Conclusions: Findings revealed that high risk for RTAs was amongst young male drivers, 26-35 years age range, who drove motorcycles. The most potential for RTAs to occur was on Fridays and Wednesdays and are more pronounced after 6 pm. The risk factors of RTAs are a result of a combination of several factors, as opposed to one.
