Population Density

Background: Road-traffic injuries are a key cause of death and disability in low-income and middle-income countries, but the effect of city characteristics on road-traffic mortality is unknown in these countries. The aim of this study was to determine associations between city-level built environment factors and road-traffic mortality in large Latin American cities. Methods: We selected cities from Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico, Panama, and Peru; cities included in the analysis had a population of at least 100 000 people.
This study supports SDGs 3 and 6 by showing that a handwashing intervention involving disgust-inducing messages, combined with the provision of handwashing stations in Abidjan, Côte d'Ivoire, successfully increased rates of handwashing with soap after toilet use. These findings demonstrate the effectiveness of combining health-based messaging with non-health-based messaging when implementing water, sanitation, and hygiene interventions.
Diagram showing the age-adjusted cumulative COVID-19 mortality between Jan 24, 2020, and Feb 28, 2021, by disability status and sex. Upper and lower lines of each colour represent the upper and lower bounds of the bootstrapped 95% CI.
Background: People with learning disabilities are at substantially increased risk of COVID-19 mortality, but evidence on risks of COVID-19 mortality for disabled people more generally is limited. We aimed to use population-level data to estimate the association between self-reported disability and death involving COVID-19 during the first two waves of the COVID-19 pandemic in England.
This study supports SDGs 3 and 10 by evaluating whether residential racial segregations in the USA could restrict the capacity for social distancing, leaving African Americans potentially more exposed to COVID-19.
This study supports SDGs 3 and 6 by identifying passive chlorination at the point of collection as an effective and scalable strategy for reducing diarrhoea in children and improving access to safe and affordable drinking water in a low-income urban setting.
