A new study from the USC Leonard Davis School of Gerontology shows that the behavioural responses to COVID-19 differed by age. The research, led by Jung Ki Kim, research associate professor at the USC Leonard Davis School, examined how age affected the practice of preventive and risky behaviours in response to COVID-19 and how these behaviours changed over the first three months of the pandemic.
The article was co-authored by University Professor Eileen Crimmins, holder of the AARP Chair in Gerontology, and appeared online in the journal PLOS One on November 10, 2020.
Among the study’s findings:
- At the beginning of the quarantine period, older people were no more likely than younger people to practise preventive behaviours in response to the pandemic. In fact, in March, older people were no different from younger people in their engagement in wearing a facemask, washing hands frequently, cancelling personal and social activities, and avoiding high-risk people, public places and eating at restaurants. However, by May, older people were more likely to implement such behaviours.
- Except for wearing a mask, people adopted preventive activities in the first month but then reduced the modification of their behaviours somewhat after April, so that the percentage of people taking these preventive behaviours was lower in May than April. However, the use of facemasks continued to increase over time such that the percentage in May was about double that of April.
- In terms of risky behaviours, older people were less likely than younger people to have close contact with non-household people and less likely to go to other people’s homes a month after the pandemic started. However, both younger and older people tended to resume these potentially risky social behaviours as the pandemic progressed.
‘It is encouraging to observe older people taking more preventive personal behaviours as the pandemic progressed as this may have alleviated their risk of infection,’ said Kim. ‘However, at the same time, it is concerning that people increased risky social behaviours over time, particularly older people, who could have more adverse consequences from meeting with family and friends.’
The researchers speculate that some risky behaviours, such as visiting or being visited by non-household friends and relatives, may be behaviours that people, regardless of age, cannot forgo for months.
Kim and Crimmins analyzed three waves of response data from the Understanding America Study’s COVID-19 panel on how often more than 5000 participants, ranging in age from 18 to 101 and categorized into age groups of 18-34, 35-54, 55-64, and 65+, performed five virus-mitigating behaviours during the months of March, April and May of the coronavirus pandemic:
- Wearing a face mask
- Washing hands with soap or using hand sanitizer several times per day
- Cancelling or postponing personal or social activities
- Avoiding eating at restaurants
- Avoiding public spaces, gatherings or crowds. In addition, they also looked at risky health behaviours
Risky health behaviours include going to another person’s residence; having outside visitors such as friends, neighbours or relatives at one’s home; attending a gathering with more than 10 people, such as a party, concert or religious service; or having close contact (within six feet) with someone who doesn’t live with the respondent.
‘Because there is no immediate cure and little treatment for the condition, while scientists are attempting to develop and distribute a vaccine, proper personal and social practices may be the only route to reducing infection for older people,’ said Kim.
‘Given more severe consequences for older people once infected, older people should be strongly encouraged to continue taking preventive personal behaviours and not to increase risky behaviours since the virus could be transmitted during these activities.’
In addition to age, the researchers also found that other characteristics are related to behaviour during the ongoing pandemic: being female, Black, Hispanic or Asian; having a higher education; having underlying conditions; residing in a state where the COVID-19 outbreak was more prevalent, and trusting CNN more than Fox News were all linked to practising more preventive behaviours in response to COVID-19.
The researchers say that the consistently higher preventive behavioural response of Blacks, Hispanics, and Asians may reflect the knowledge that the pandemic was differentially affecting communities of colour. They add that proper work accommodation and protective guidelines may need to be made for persons who are engaging in risky behaviours out of necessity.
They also say that people may also respond to state and local government mandates and campaigns on the importance of face-covering in states where infection cases are greater, and that apolitical, scientifically based recommendations for behaviour through the media could have changed behaviours.
