ObjectivesHealth advocacy (HA) is a core competency in Canadian obstetrics and gynaecology postgraduate programs. Our objectives were to assess awareness and understanding of the health advocate role among trainees, their current HA training and exposure, and the desire and needs for future HA training. MethodsAn anonymous, cross-sectional, Internet-based, selfreported health advocacy questionnaire was distributed to Canadian obstetrics and gynaecology trainees. Descriptive analysis was conducted for all study variables. Chi-square tests, Cochran-Armitage trend test, and Fisher exact test were performed where appropriate. ResultsMost trainees (93.9% of respondents) were aware of the CanMEDS HA role and that it is a training objective (92.9%). Only 52.4% had clear objectives while 58.4% understood the role requirements. Most trainees (95.1% of respondents) felt HA was important to address during training. Only 30.4% had HA training, and just 36.3% felt their training needs were addressed. Training included teaching sessions (11.9%), clinical teaching (4.7%), and role modelling (4.7%). Although 82.9% of respondents had HA opportunities with patients, there were fewer opportunities at community (45.1%) and societal (30.0%) levels. Awareness of community groups and activities was low (28.6%), and few (20.0%) had participated in community advocacy programs during their residency. Incorporating advocacy activities into training was valued (80.0%). Many residents supported mandatory HA training (60.0%), more training time on HA experiences (66.3%), and HA experiences during protected time (71.3%). ConclusionAwareness of and interest in the HA role is high, but clear objectives and training are lacking or inadequate. A standardized curriculum would ensure health advocacy exposure and emphasize active participation in community and societal activities. Trainees support this training during protected time.
