Paper
Objectives
Growing attention has been given to considering sex and gender in health research. However, this remains a challenge in the context of retrospective studies where self-reported gender measures are often unavailable. This study aimed to create and validate a composite gender index using data from the Canadian Community Health Survey (CCHS).
Methods
According to scientific literature and expert opinion, the GENDER Index was built using several variables available in the CCHS and deemed to be gender-related (e.g., occupation, receiving child support, number of working hours). Among workers aged 18–50 years who had no missing data for our variables of interest (n = 29,470 participants), propensity scores were derived from a logistic regression model that included gender-related variables as covariates and where biological sex served as the dependent variable. Construct validity of propensity scores (GENDER Index scores) were then examined.
Results
When looking at the distribution of the GENDER Index scores in males and females, they appeared related but partly independent. Differences in the proportion of females appeared between groups categorized according to the GENDER Index scores tertiles (p < 0.0001). Construct validity was also examined through associations between the GENDER Index scores and gender-related variables identified a priori such as choosing/avoiding certain foods because of weight concerns (p < 0.0001), caring for children as the most important thing contributing to stress (p = 0.0309), and ability to handle unexpected/difficult problems (p = 0.0375).
Conclusion
The GENDER Index could be useful to enhance the capacity of researchers using CCHS data to conduct gender-based analysis among populations of workers.

Trained in pharmacoepidemiology at the Faculty of Pharmacy of Montreal University, Anaïs Lacasse is an associate professor in the Department of Health Sciences at the University of Quebec in Abitibi-Témiscamingue (UQAT), Quebec, Canada. She is a Junior 2 scholar of the Fonds de recherche du Québec - Santé (FRQS) in partnership with the Quebec SPOR Support Unit and her research program aims to better understand the treatment of chronic pain in the real-world clinical context. Specifically, 3 complementary research axes are explored: 1) The healthcare trajectories of people living with chronic pain, 2) The use of drugs for the treatment of chronic pain, and 3) The linkage and validation of databases and measurement scales for research in this field. Anaïs Lacasse is actively involved in several FRQS research networks, especially as the Co-Director of the Quebec Pain Research Network (QPRN) and member of the Steering Committee of the Quebec Network on Drug Research (RQRM).
