While researchers often, incorrectly, use the variables sex and gender interchangeably, these 2 variables are different. We conducted a content analysis of 239 randomly selected research articles, with the purpose of describing how researchers have used sex and gender in studies published in nursing journals and identifying opportunities for improved clarity and precision in measuring these 2 variables. We found that significant improvement is needed in the way these variables are used/reported. © 2021 Wolters Kluwer Health, Inc. All rights reserved.
