Abstract:
Antibiotics are essential agents that have greatly reduced human mortality due to infectious diseases. Their use, and sometimes overuse, have increased over the past several decades in humans, veterinary medicine and agriculture. However, the emergence of resistant pathogens is becoming an increasing problem that could result in the re-emergence of infectious diseases. Antibiotic prescription in human medicine plays a key role in this phenomenon. Under selection pressure, resistance can emerge in the commensal flora of treated individuals and disseminate to others. However, even if the effects of antimicrobial use on resistance is intuitively accepted, scientific rationales are required to convince physicians, legislators and public opinion to adopt appropriate behaviours and policies. With this review, we aim to provide an overview of different epidemiological study designs that are used to study the relationship between antibiotic use and the emergence and spread of resistance, as well as highlight their main strengths and weaknesses.
Insights
Antibiotic resistance is a growing threat due to increased use. This review examines epidemiological study designs to understand the link between antibiotic use and resistance emergence and spread.
Area of Science:
- Microbiology and Epidemiology
- Public Health
Background:
- Antibiotics have significantly reduced infectious disease mortality.
- Increased antibiotic use in humans, veterinary medicine, and agriculture has led to the emergence of resistant pathogens.
- Antibiotic resistance poses a significant threat, potentially leading to the re-emergence of infectious diseases.
Purpose of the Study:
- To provide an overview of epidemiological study designs used to investigate the relationship between antibiotic use and the emergence and spread of resistance.
- To highlight the strengths and weaknesses of various epidemiological study designs in this field.
Main Methods:
- Review of epidemiological study designs.
- Analysis of strengths and weaknesses of each design in the context of antibiotic resistance research.
Main Results:
- Different epidemiological study designs offer varied approaches to understanding antibiotic resistance.
- Each design has specific advantages and limitations impacting the ability to establish causal links between antibiotic use and resistance.
Conclusions:
- Robust scientific evidence from appropriate epidemiological studies is crucial for informing policies and behaviors to combat antibiotic resistance.
- Understanding the methodologies is key to effectively addressing the global challenge of antimicrobial resistance.

Study Designs in Epidemiology
Observational studies are those where the researcher does not intervene but rather observes natural variations. They include cross-sectional, cohort, and case-control studies.
