A recent study has revealed that women have a significantly higher risk of developing long COVID compared to men, with women aged 40 to 55 being the most vulnerable.
Conducted by researchers at UT Health San Antonio as part of the nationwide RECOVER initiative, the study aimed to understand the long-term health effects of COVID-19 and identify key risk factors for long COVID.
The research followed 12,276 participants from across the United States and found that women were 31% more likely to develop long COVID than men, even after accounting for factors like race, ethnicity, COVID variant, illness severity, and social determinants of health.
This association was influenced by age, pregnancy status, and menopausal status, providing new insights into how biological sex and life stages impact the risk of this condition.
Long COVID: A Growing Concern
Long COVID, also known as post-COVID condition, affects a substantial portion of people who recover from acute COVID-19. Symptoms can include fatigue, brain fog, shortness of breath, and joint pain, often lasting for months or even years after the initial infection.
Globally, SARS-CoV-2, the virus that causes COVID-19, has infected over 700 million people and resulted in approximately 7 million deaths. While many recover fully, the long-term effects on physical and mental health are a growing concern.
Previous research has shown that men are more likely to experience severe cases of COVID-19 and have higher mortality rates.
However, emerging studies suggest that women are at greater risk for lingering symptoms after recovering from the acute phase of the illness. This mirrors patterns seen in other conditions like autoimmune diseases, which disproportionately affect women.
The RECOVER study analyzed data from participants enrolled at 83 sites across 33 U.S. states, Washington, D.C., and Puerto Rico between October 2021 and July 2024.
To qualify, participants needed to have a follow-up visit at least six months after their initial COVID-19 infection. Gender was defined based on the self-reported sex assigned at birth.
Researchers measured the presence of long COVID using a detailed symptom questionnaire, evaluating a wide range of health and social factors. To ensure accuracy, they employed statistical methods to balance variables like age, vaccination status, comorbidities, and COVID variants.
The results showed that women aged 40 to 55 had an even higher risk, with menopausal women 42% more likely to develop long COVID than men and non-menopausal women 45% more likely. On average, the age of infection for the female participants was 46 years.
The study highlights several possible reasons for the higher risk in women. Biological factors, such as hormonal changes during menopause, may influence the immune system’s response to the virus. Additionally, women may experience heightened stress or inflammatory responses, both of which could contribute to lingering symptoms.
The study also suggests that differences in healthcare access and utilization might play a role, although the data adjusted for social and economic factors to minimize these biases.
Interestingly, the study found that other conditions linked to COVID-19, such as autoimmune diseases or diabetes, did not fully explain the gender disparity in long COVID risk. This points to the need for more research to uncover the underlying mechanisms.
The study provides critical insights into long COVID and highlights the importance of considering gender differences when diagnosing and treating the condition. Women, particularly those in midlife, should be aware of their heightened risk and seek medical attention if they experience ongoing symptoms after recovering from COVID-19.
Dr. Dimpy Shah, the lead researcher, emphasized the significance of these findings, noting that the study’s large sample size and diverse participant pool allowed for a more detailed analysis than previous studies. She hopes this research will inspire further investigations into why long COVID risk varies based on sex and life stage.
Healthcare professionals could use this information to tailor prevention and treatment strategies for long COVID. For instance, women in high-risk groups might benefit from closer monitoring or early interventions to mitigate long-term effects.
The study also underscores the importance of addressing broader social and economic factors that contribute to health disparities.
This research marks a significant step forward in understanding long COVID, particularly its impact on women. While it doesn’t answer all the questions about why women face a higher risk, it provides a foundation for future studies and highlights the need for gender-specific approaches to care.
As long COVID continues to affect millions worldwide, such insights will be crucial in improving outcomes and ensuring equitable healthcare for all.
