“…We used a multiple-group interrupted time series analysis (ITSA) with a control group to estimate the effect of Law 20606 on the price index 20. This method is used widely to assess the impact and evaluate the effectiveness of interventions applied in specific moments 21–24. ITSA uses multiple and consecutive moments in time, preintervention and postintervention, allowing us to view the evolution of the time series and test the assumption of parallel trends preintervention (ie, that treated and control groups have the same statistical characteristics—level and trend—during the preintervention period) 25.…”

IntroductionThis study assesses the impact on prices of the 2016 Chilean comprehensive food policy package, centred around front-of-package warning labels for food and beverages high in saturated fats, sugars, calories and/or salt, on food and beverage prices, labelled or not.MethodsData from Kantar WorldPanel Chile, from January 2014 to December 2017, were used. The methodology implemented was interrupted time series analyses with a control group on Laspeyres Price Indices on labelled food and beverage products.ResultsAfter the regulations were implemented, prices among different categories of products (eg, high-in; reformulated but still high-in; reformulated and not high-in; not high-in) did not change with regulations relative to the control group. Specific price indices (relative to the control group) for households from different socioeconomic strata remained unchanged.ConclusionsEven where reformulation was extensive, we found no evidence that it was associated with price changes, at least during Chile’s first year and a half of regulation implementation.

“…We included several sensitivity analyses with the goal of testing for potential biases. To isolate the effect of sobriety checkpoints from prior drink-driving policies (Colchero et al 2020 ), we excluded municipalities that are part of Mexico City (sensitivity 1). To test for potential heterogeneity in the program (i.e., multiple versions of the treatment), we excluded 17 municipalities for which the program was discontinued during the study period (sensitivity analysis 2).…”

“…To improve the enforcement of BAC limits, local and national level policies have been introduced. In 2003, Mexico City created the program “Conduce Sin Alcohol” (CSA), which introduced sobriety checkpoints to monitor the breath alcohol concentration of drivers (Colchero et al 2020 ). The CSA program was associated with a reduction in traffic-related deaths of 0.08 per 1 million people per month after the program, compared to the pre-intervention trend (Colchero et al 2020 ).…”

Background Up to a third of global road traffic deaths, and one in five in Mexico, are attributable to alcohol. In 2013, Mexico launched a national sobriety checkpoints program designed to reduce drink-driving in municipalities with high rates of alcohol-related collisions. Our study measured the association between the sobriety checkpoints program and road traffic mortality rates in 106 urban municipalities. Methods We leveraged data from the Salud Urbana en America Latina (SALURBAL), which compiles health and environmental data from cities with over 100,000 residents. Death data from 2005 to 2019 (i.e., outcome) were from official vital statistics. Among 106 Mexican municipalities defined as priority areas for intervention, 54 adopted the program (i.e., treatment) in 2013, 16 municipalities did so in 2014, 16 in 2015, 10 in 2016, 7 in 2017, and 2 in 2019. We used a difference-in-difference approach with inverse probability weighting adapted to a context where program adoption is staggered over time. Results There was a 12.3% reduction in road traffic fatalities per 10,000 passenger vehicles in the post-treatment period compared to the pre-treatment period (95% Confidence Interval, − 17.8; − 6,5). There was a clear trend of decline in mortality in municipalities that adopted the program (vs. comparison) particularly after year 2 of the program. Conclusions In this study of 106 municipalities in Mexico, we found a 12.3% reduction in traffic fatalities associated with the adoption of sobriety checkpoints. There was a clear trend indicating that this association increased over time, which is consistent with sustained changes in drink-driving behavior. These findings provide support and insight for efforts to implement and evaluate the impact of sobriety checkpoint policies across Latin America.

“…Regarding mobility in Mexico City, this has meant that successive changes in legislation and practices have not only fallen short of expectations but are perceived as only cosmetic changes made to appease protesters. Thus, while some policies have improved road safety -like the reduction of drunk driving (Colchero et al 2020) -many cyclists often feel at the mercy of aggressive motorists. For these reasons, activists break rules on a regular basis not only to get the attention of authorities, but to alert all urban dwellers about the illegitimacy of some rules.…”

Cycloactivism in Mexico City

Cycling in Mexico City is dangerous. But over the last two decades it has become less so. New cycleways, a large public bicycle-sharing scheme, various government cycling promotion projects and an abundance of official signalling demanding respect for cyclists have made bicycles visible as worthy vehicles on city streets. For cycloactivists, however, such improvements are not enough. Cyclists are frequently harassed, attacked or run over by motorists. Cycloactivists thus demand more and better cycleways as well as increased measures to address injustices in mobility issues across the city. They do so through protests, information campaigns, public performances and academic debates, and crucially, by cycling through city streets. This means that they use their bodies as symbols, to highlight their vulnerability. Along the way, they often break existing traffic rules to highlight how unfair they are and to draw attention to other demands. I refer to their efforts as experiential cycloactivism, which highlights cyclists making themselves vulnerable as a means of denouncing illegitimate rules and policies that need to be changed. I conclude the analysis by suggesting that their style of rule-breaking is a type of ritual with which they seek to improve the city, not burn it down.
