“this is a particularly important topic right now because, in addition to life’s other major events, the covid-19 pandemic is another disruption of everyone’s daily routines and activity levels,” lane-cordova said.
instead of conducting research in the traditional sense of monitoring thousands of people from several age groups over many years, researchers dug into studies that already existed and compiled the results into one document.
no specific figures were given for the decreases in physical activity, though data regarding ages for each type of event were provided, as was whether activity stayed similar or decreased.
for instance, starting a new school was only related to people aged about five to 20 years old. a decrease in activity and increase in sedentary behaviour was found for each of these age groups when starting school.
there were some events that had either no effect on physical activity, or inconsistent findings, such as being re-married, divorce, job loss, and even homelessness.
events with no systematic data published so far include entry to childcare, summer vacation for school kids, and major societal events such as the 9/11 terrorist attacks or the ongoing covid-19 pandemic.
