- Drink driving and speeding in Sao Paulo, Brazil: empirical cross-sectional study (2015-2018)(2019) ANDREUCCETTI, Gabriel; LEYTON, Vilma; CARVALHO, Heraclito Barbosa; SINAGAWA, Daniele M.; BOMBANA, Henrique S.; PONCE, Julio C.; ALLEN, Katharine A.; VECINO-ORTIZ, Andres I.; HYDER, Adnan A.Objectives To evaluate the prevalence of drink driving and speeding during 2015-2018 in Sao Paulo, Brazil. Design Cross-sectional observational study. Setting Roads representing the five main regions of the city of Sao Paulo in Brazil, one of the world's largest urban areas. Participants Drivers (N=10294) stopped at routine roadside breath testing checkpoints and those driving in selected roads for speeding measurement (N=414664). Primary and secondary outcome measures Microwave radar guns were used to measure the speed of vehicles, while the prevalence of drivers under the influence of alcohol was observed in police checkpoints. Data were collected during three consecutive years (2016-2018) following a baseline study established in 2015 using a city-level representative sample of observational data representing all days of the week. Results Alcohol-related fatalities kept at a constantly high percentage, with 39% of road traffic deaths involving alcohol in 2016. Drivers testing above the legal breath alcohol concentration limit showed a decreasing trend, from 4.1% (95% CI 2.9% to 5.5%) at baseline to 0.6% (95% CI 0.2% to 1.2%) in the end of 2018 (p<0.001); however, more than half of drivers refused breath tests at checkpoints despite steep legal penalties. The prevalence of speeding among all vehicles decreased from 8.1% (95% CI 7.9% to 8.2%) to 4.9% (95% CI 4.7% to 5.1%) by the end of 2016 (p<0.001), but then increased again to 13.5% (95% CI 13.2% to 13.9%) at the end of the study period (p<0.001). Conclusions Drink driving rates have reduced, likely due to an increase in drivers refusing breath alcohol tests, while speeding rates have increased significantly by the end of the study period, particularly among motorcycles. Future strategies aiming at reducing road traffic injuries in the major Brazilian city should tailor drink driving and speeding enforcement based on the new evidence provided here.
- Loaded dice: A game theory analysis of drunk driving laws in Brazil(2018) PONCE, Julio de Carvalho; KAWAUTI, Marcela de Carvalho Ponce; ANDREUCCETTI, Gabriel; CARVALHO, Heraclito Barbosa deObjective: The aim of the study was to evaluate whether the current legislation would encourage drunk drivers to refrain from taking a breathalyzer and thus avoid jail time. Method: Brazilian traffic laws currently have 3 possible punishments for drivers suspected of driving under the influence: A fine and suspension of license for 12 months if the breathalyzer result is under 0.3 mg/L (by law; a result up to 0.33 mg/L would receive the same punishment due to a later regulatory document) but positive; the same punishment for refusal to take a breathalyzer test; and up to 3 years of jail time and license cancellation if over 0.3 mg/L. Analysis was done using decision tree analysis as well as game theory to evaluate the rational choice for drunk drivers according to possible financial loss. Results: The authors have found that the rational choice for a drunk driver is not taking the breathalyzer test to avoid heavier penalties. This, in turn, contributes to the inefficacy of the law. Conclusion: The authors have also calculated that the fine for refusing should be around 2.5 times higher so that the economic equilibrium would shift toward encouraging drivers to take the test. This should also be accompanied by other incentives to promote safe behavior while driving.
- Reducing the legal blood alcohol concentration limit for driving in developing countries: a time for change? Results and implications derived from a time-series analysis (2001-10) conducted in Brazil(2011) ANDREUCCETTI, Gabriel; CARVALHO, Heraclito B.; CHERPITEL, Cheryl J.; YE, Yu; PONCE, Julio C.; KAHN, Tulio; LEYTON, VilmaAims In Brazil, a new lawintroduced in 2008 has lowered the blood alcohol concentration limit for drivers from 0.06 to 0.02, but the effectiveness in reducing traffic accidents remains uncertain. This study evaluated the effects of this enactment on road traffic injuries and fatalities. Design Time-series analysis using autoregressive integrated moving average (ARIMA) modelling. Setting State and capital of Sao Paulo, Brazil. Participants A total of 1 471 087 non-fatal and 51 561 fatal road traffic accident cases in both regions. Measurements Monthly rates of traffic injuries and fatalities per 100 000 inhabitants from January 2001 to June 2010. Findings The new traffic law was responsible for significant reductions in traffic injury and fatality rates in both localities (P < 0.05). A stronger effect was observed for traffic fatality (-7.2 and -16.0% in the average monthly rate in the State and capital, respectively) compared to traffic injury rates (-1.8 and -2.3% in the State and capital, respectively). Conclusions Lowering the blood alcohol concentration limit in Brazil had a greater impact on traffic fatalities than injuries, with a higher effect in the capital, where presumably the police enforcement was enhanced.
- Alcohol-related traffic accidents with fatal outcomes in the city of Sao Paulo(2011) PONCE, Julio de Carvalho; MUNOZ, Daniel Romero; ANDREUCCETTI, Gabriel; CARVALHO, Debora Goncalves de; LEYTON, VilmaAims: The aims of the present study were to characterize fatal traffic accident victims in a major urban center in Brazil and their association with alcohol consumption. Methods: Cross-sectional study of 907 fatal traffic accident victims in Sao Paulo, in 2005. Results: Adult males between the ages of 25 and 54 represented the majority of cases with positive blood alcohol concentrations (BAC). Overall, males had a higher proportional BAC and mean BAC than females. Pedestrians, particularly those with no detectable BAC, were typically older than other victims. Most accidents (total and BAC-positive) happened on weekends between midnight and 6 a.m. Considering all victims, 39.4% were positive (BAC over 0.1 g/l). When only drivers (automobile, motorcycle and bicycle) were evaluated. 42.3% had BAC over the legal limit (0.6 g/l). Conclusions: Alcohol is associated with nearly half of all traffic accident deaths in the city of Sao Paulo. especially for days and times associated with parties and bars (weekends between 12 a.m. and 6 a.m.).
- PREVALENCE OF BEHAVIORAL RISK FACTORS FOR ROAD TRAFFIC INJURIES IN THE CITY OF SAO PAULO: FINDINGS FROM THE BLOOMBERG INITIATIVE FOR GLOBAL ROAD SAFETY (BIGRS) 2015-2017(2018) ANDREUCCETTI, Gabriel; LEYTON, Vilma; CARVALHO, Heraclito B.; SINAGAWA, Daniele M.; BOMBANA, Henrique S.; PONCE, Julio C.; ALLEN, Katharine A.; VECINO-ORTIZ, Andres I.; HYDER, Adnan A.
- Comparison of traffic data and blood alcohol concentration among fatally injured drivers in Norway and Sao Paulo, Brazil, 2005-2015(2019) PONCE, Julio de Carvalho; ANDREUCCETTI, Gabriel; GONCALVES, Raphael Eduardo Marques; GJERDE, Hallvard; BOGSTRAND, Stig Tore; VALEN, Anja; LEYTON, Vilma; CARVALHO, Heraclito Barbosa deObjective: Road traffic crashes (RTCs) are responsible for a large number of deaths worldwide, but low- and middle-income countries frequently present higher rates of deaths; for example, Norway, a high-income country, has a rate of 2.0 drivers killed per 100,000 inhabitants, whereas Brazil, a middle-income country, has a rate of 18.4. A significant fraction of RTCs are related to use of psychoactive substances, especially alcohol, due to its availability, legality, and relatively low price. The aim of the present study was to evaluate differences in alcohol-related fatal RTCs in Sao Paulo, the largest city in Brazil, and Norway during an 11-year period (2005-2015). Methods: The authors compared databases of drivers killed in RTCs in Sao Paulo and in Norway, a country renowned for its success in reducing traffic fatalities and keeping them at a low level. Results: In total, 772 victims from Norway (11 years, 2005 to 2015) and 584 victims from Sao Paulo (2 years, 2005 and 2015) were analyzed. Sao Paulo presented higher proportions of motorcycle drivers, men involved in RTCs, and blood alcohol concentration (BAC)-positive cases. The mean BAC for alcohol-positive cases was similar in both sites. For both regions, the percentage of alcohol-positive cases decreased during the study period (from 45.6% to 35.3% in Sao Paulo and from 24.4% to 15.8% in Norway) but remained higher for Sao Paulo. Conclusions: The study shows a different profile of RTC victims and higher alcohol consumption among drivers in Sao Paulo. The differences between the sites can possibly be attributed to public policies regarding traffic safety and alcohol control, which could be further improved by following the Norwegian model in Sao Paulo.
