New research from Unity Health Toronto examined changes in mobility during COVID-19 lockdowns in Ontario and found that mobility decreased the most in wealthier neighbourhoods with fewer essential workers.

She was mentored by Physician Scientist and Associate Professor Dr. Sharmistha Mishra, and Prof. Rafal Kustra, at the Dalla Lana School of Public Health. The project was supported by NSERC, including CANMOD (an Emerging Infectious Disease Modeling Network funded by NSERC). The research combined cellphone mobility data with neighbourhood-level measures of household income and proportion of essential workers. The team quantified changes in mobility in response to two restriction policies across five regions in Ontario, Canada in early and late 2020. The team examined whether reductions in mobility varied by neighbourhood-level socioeconomic measures. The researchers found that the reductions in mobility were much smaller during the second restriction policy in late 2020, suggesting that the effect of restrictions on mobility changes may saturate over subsequent restrictions. Decreases in mobility in response to restrictions were more pronounced in wealthier neighbourhoods with fewer essential workers. The study highlights the need for additional approaches to reduce health inequities at the intersections of income and occupation when addressing large epidemics, the research team concludes. “By definition, essential workers could not ‘shelter in place’ during restrictions. In epidemics, it is never enough to look just at the overall impact of strategies or policies. Quantifying what worked and for whom they worked (and ideally why they worked or did not work) can help improve public health measures so that policies and strategies meaningfully reduce health inequities during an epidemic,” said Mishra.
