In studying the epidemiology of a virus (COVID-19), the urban context must not be ignored

June 11, 2026

The high concentration of people and activities in cities makes them vulnerable to various stressors such as natural and man-made disasters. In the recent pandemic, the cities are the places where the transmission started. We investigated the impact of social, economic, and environmental indicators on the rate of COVID-19 disease in the neighborhoods of Urmia City, Iran. Our results show that the number of employees, gross residential density, number of elderly people, building density, commercial density and road density have a significant relationship in predicting the epidemic.

Out-of-home built environment characteristics of urban heritage cores and their impact on age-friendliness

June 10, 2026

The deterioration of the built environment, as well as poor traffic and pedestrian conditions, creates obstacles to active mobility, active ageing and functional abilities among older adults residing in heritage city cores. This has negative impacts on their social inclusiveness, quality of life and well-being. The walled city, which encompasses Jaipur’s heritage neighbourhood, is one of the few planned cities in India, extending back to the 18th century, and is considered a tourist attraction. With an in-depth study, we use Jaipur’s walled city to examine how supporting a better quality of life for an ageing population can have co-benefits for the tourism economy.

Constraints, compromises and decision-making: What drives healthy and unhealthy diets in Urban Informal Settlements

June 9, 2026

We examined the factors that limit and enable the uptake of healthy diets among urban populations with multiple socio-economic vulnerabilities. By exploring the interconnected economic, social and environmental influences, we aimed to generate context-specific evidence that can inform effective and targeted action to support progress towards achieving global nutrition targets in the context of triple burden of malnutrition and increasing concern on high incidences of diet-related diseases in rapidly urbanizing areas.

How does the built environment and traffic impact air pollution, and what does this mean for public health? 

April 23, 2026

Air pollution threatens public health globally. Our exposure to air pollution is influenced by transport. Transport is both a prominent source of air pollution and an important determinant in our exposure to it. The built and natural environment also dictate how, when and where we travel, and what we are exposed to. We provide a comprehensive review of these relationships and their interactions.
