The Effect of a Global Health Shock on Preventive Drug Intake: Evidence from SHARE 2020-2022 for 15 European Countries
This study analyzes data from 4,642 respondents across 15 European countries during the COVID-19 pandemic to identify that being female, more educated, having income, experiencing worse health, or facing job loss due to the crisis significantly increases the likelihood of engaging in potentially harmful preventive drug self-medication.

When a sudden health crisis strikes, people often look for ways to protect themselves before they even feel sick. This instinct to act early is a core part of how humans interact with the medical world. Researchers study this behavior using a framework that looks at three main things: who a person is, what resources they have, and what their body needs. "Who a person is" includes factors like age, gender, and education. "Resources" covers money and access to care. "Needs" refers to how a person feels physically, such as whether they have a specific illness or just feel unwell. Understanding how these pieces fit together helps explain why some people reach for medicine to prevent a disease while others do not, especially during a global emergency like the pandemic.
A recent study set out to understand exactly this dynamic during the COVID-19 pandemic. The researchers examined data from over 4,600 people across fifteen European countries, tracking their habits between 2020 and 2022. They wanted to see what drove people to take drugs specifically to prevent the virus, a behavior that can sometimes be risky if done without medical guidance. By looking at a wide range of personal details, from income levels to self-reported health, the team built a clear picture of who was most likely to engage in this preventive behavior and why.
The study found that certain groups were significantly more likely to take preventive medication. Women were more likely to do so than men, as were people with higher levels of education. Surprisingly, having an income was also linked to a higher likelihood of taking these drugs, even though one might assume financial security would lead to more cautious, doctor-guided choices. Similarly, people who were out of work because of the pandemic were more likely to take preventive measures than those who remained employed. Health status played a major role as well; those who rated their own health as poor were more inclined to use preventive drugs.
The researchers also looked at how symptoms influenced these decisions. When people reported feeling symptoms, their likelihood of taking preventive drugs increased, but this depended heavily on their other circumstances. For instance, if a person had symptoms and was in poor health, or if they had symptoms and a steady income, they were even more likely to take medication. However, age told a different story. While older people generally might be expected to be more cautious, the study found that among those reporting symptoms, the older the person was, the less likely they were to take preventive drugs. This suggests that age acts as a moderating factor, perhaps making older individuals more hesitant to self-medicate even when they feel unwell.
Not everything the researchers looked for turned out to be a driver. The study explicitly found that relationship status—whether someone was single or in a couple—did not influence the decision to take preventive drugs. Financial distress, or the difficulty of making ends meet, also showed no clear impact on the behavior. While some might assume that money worries would stop people from buying medicine, the data suggested that financial hardship did not significantly change the odds of taking preventive drugs in this context. Furthermore, the country where a person lived did not explain the behavior in a simple way, although specific nations like the Czech Republic and Estonia showed much higher rates of preventive drug use compared to others, likely due to local differences in how people reported their habits.
The study concludes that during a health shock, the decision to take preventive medication is not random. It is shaped by a mix of personal identity, economic standing, and physical condition. The findings highlight that women, the educated, the employed, and those in poor health are the primary groups turning to preventive drugs. At the same time, the research rules out the idea that relationship status or the simple struggle to pay bills are the main forces at play. By mapping these behaviors, the study offers a clearer view of how people navigate health risks when the world is in crisis, providing valuable insight for policymakers who need to understand public behavior during future health emergencies.
