INTRODUCTION
The emergence of breakthrough SARS-CoV-2 infections during the Omicron wave has reignited the urgency to understand factors influencing infection risk and clinical progression. This study, conducted across six provinces in China, adopts a case–control design involving over 20,000 participants to identify predictors for the incidence, persistence, and severity of symptoms after COVID-19 infection. Through matching cases and controls on age, sex, and region, and analyzing a broad range of individual-level variables using multivariate logistic regression, the study provides a comprehensive exploration of host and behavioral determinants. Key findings reveal associations between lifestyle factors, such as tea and coffee consumption or alcohol intake, and infection risk or symptom severity. Notably, both underweight and overweight status emerged as significant predictors of poor outcomes. By incorporating real-world surveillance data and considering vaccination history, this research offers critical insight into COVID-19 symptom trajectories in a post-vaccine context. Its emphasis on individualized risk profiling offers a foundation for targeted public health interventions and long-term management of post-COVID complications in Chinese adults.
DEMOGRAPHIC AND LIFESTYLE DETERMINANTS OF INFECTION
Demographic and behavioral attributes play a crucial role in shaping the risk of breakthrough SARS-CoV-2 infections. In this study, individuals with occasional alcohol consumption, tea and coffee habits, or overweight status exhibited a higher probability of infection. Conversely, weekly alcohol intake and smoking appeared to reduce infection risk, challenging conventional assumptions and suggesting complex behavioral-health interactions. Female participants showed greater vulnerability to persistent and severe symptoms, potentially reflecting hormonal, immunological, or sociocultural factors. These associations emphasize the need to consider nuanced lifestyle profiles in risk communication and prevention efforts.
THE ROLE OF COMORBIDITIES IN COVID-19 SEVERITY
The presence of pre-existing medical conditions significantly influenced both the likelihood and outcomes of SARS-CoV-2 breakthrough infections. Comorbidities were not only linked with increased infection risk but also with a higher probability of developing prolonged or moderate-to-severe symptoms. This reinforces earlier findings that chronic diseases amplify COVID-19-related complications, even in the post-vaccination era. Furthermore, individuals with a history of immunotherapy also demonstrated greater susceptibility, underscoring the importance of tailored clinical management for immunocompromised populations.
NUTRITIONAL STATUS AND WEIGHT-RELATED RISKS
Nutritional and bodyweight indicators were strongly associated with both infection susceptibility and symptom severity. The study found that being underweight or overweight elevated the odds of developing severe or persistent symptoms post-infection. This reflects a dual burden wherein both nutritional insufficiency and metabolic overload may impair immune resilience. Public health recommendations should therefore promote balanced nutrition as a critical component of infection preparedness, particularly in the face of evolving SARS-CoV-2 variants.
VACCINATION TIMING AND INFECTION OUTCOMES
A longer duration since the last COVID-19 vaccination was linked with increased infection risk in the cohort studied. This temporal association highlights waning immunity as a key vulnerability in the population, especially during high-transmission phases like the Omicron wave. The data supports the strategic administration of booster doses, particularly for at-risk individuals, to maintain protective immunity. Integration of vaccination schedules with personalized risk assessments could optimize long-term health outcomes and mitigate future surges.
TOWARD PERSONALIZED COVID-19 MANAGEMENT STRATEGIES
The study’s multifactorial findings highlight the necessity for personalized prevention and management strategies for COVID-19. No single determinant was solely responsible for infection or symptom progression; rather, an interplay of lifestyle behaviors, demographic factors, and health conditions shaped the clinical course. Public health frameworks should integrate these variables to develop adaptive strategies that are sensitive to individual profiles. From vaccination timing to nutritional advice and comorbidity management, a personalized approach can better address the long-term impacts of COVID-19 on diverse populations.
