Commentary on the new sex and gender editorial policy of the Canadian Journal of Public Health.

While the concepts of both "sex" and "gender" are widely recognized as important considerations in health research, the presence of these and other key determinants of health in research findings remains quite variable in the published literature. In an effort to close this knowledge gap in relation to the implications of both sex and gender in the public health research evidence base, the Canadian Journal of Public Health (CJPH) has recently adopted an editorial policy requiring authors to ensure that their manuscripts speak to these concepts, where applicable. In keeping with the international trend in sex and gender reporting in health research, the aim of this policy shift is for CJPH to continue to advance excellence in the field of public health research, policy and practice in Canada and internationally.
