Is there gender bias in nursing research?

Area of Science:

• Nursing Research
• Health Equity
• Clinical Study Design

Background:

• Participant selection in nursing research can influence generalizability of findings.
• Historical data suggests potential gender imbalances in clinical study populations.
• Ensuring diverse representation is crucial for equitable healthcare advancements.

Purpose of the Study:

• To investigate the prevalence and significance of gender bias in participant selection within nursing research.
• To identify factors associated with potential gender disparities in study samples.
• To inform best practices for inclusive participant recruitment in nursing studies.

Main Methods:

• Analysis of 259 studies published in leading nursing journals between 2005-2006.
• Quantitative assessment of the proportion of female and male participants across studies.
• Statistical examination of bias in relation to funding, methodology, and investigator characteristics.

Main Results:

• On average, 75.3% of participants in the analyzed nursing studies were female.
• A significant 38% of studies exclusively included female participants.
• This female participant bias was statistically significant and consistent across most study types, except for those led by male investigators.

Conclusions:

• A notable and persistent bias favoring female participants exists in nursing research.
• This gender imbalance may lead to knowledge gaps concerning male health outcomes.
• Nurse researchers must actively consider sex balance in study design to ensure comprehensive and equitable research findings.
