Hormonal contraception and thrombosis: Identifying the gaps in knowledge among females in post-secondary education

Objective: To determine the current level of knowledge about hormonal contraception among young women so they may be better informed about the risks and various choices available to them regarding hormonal contraception (HC).

Methods: In an online survey-based study, data was analyzed from the anonymous responses of 675 female participants aged 18-30 years in various academic programs at two post-secondary institutions in Kingston, Ontario. Surveys explored demographics, use/type/duration of hormonal contraception, and knowledge of HC and thrombosis. Kruskal Wallis test and Spearman Correlation were used to determine differences in knowledge level about contraceptives across age groups, education levels, as well as use/type/duration of HC.

Results: 476 participants were users of HC (264 > 1 year) and 199 were non-HC users. 370 participants have a high school diploma. The knowledge level of HC risks was associated with duration of use and overall knowledge of thrombosis and HC. The knowledge level of thrombosis was correlated with duration of use, education level, and age. Participants with higher level of education or those that have been using HC for 5 years or longer had an increased knowledge surrounding thrombosis. Participants aged 24 and older had a higher knowledge of thrombosis than that of participants younger than 24. Overall, the data was used to generate a simple infographic to further educate women in this regard.

Conclusion: Misconceptions remain among young women concerning benefits and risks of HC which can be addressed by formal education.
