Intention to use emergency contraceptive pills and the role of knowledge in a Dutch national sample

Getting Intentional about Intention to Use: A Scoping Review of Person-Centered Measures of Demand

In recent years, there has been much reflection on the measures used to assess and monitor contraceptive programming outcomes. The meaning and measurement of intention‐to‐use (ITU) contraception, however, has had less attention and research despite its widespread inclusion in many major surveys. This paper takes a deeper look at the meaning and measurement of ITU around contraception. We conducted a scoping review guided by the following questions: What is the existing evidence regarding the measurement of ITU contraception? What definitions and measures are used? What do we know about the validity of these measures? We searched databases and found 112 papers to include in our review and combined this with a review of the survey instruments and behavioral theory. Our review found growing evidence around the construct of ITU in family planning programming and research. However there are inconsistencies in how ITU is defined and measured, and this tends not to be informed by advances in behavioral theory and research. Further work is needed to develop and test measures that capture the complexity of intention, examine how intention differently relates to longer‐range goals compared to more immediate implementation, and demonstrate a positive relationship between ITU and contraceptive use.

Emergency hormonal contraception in adolescence

OBJECTIVE

To analyze the degree of knowledge of Brazilian adolescents regarding emergency contraception (EC) such as correct administration, frequency of use, efficacy, mechanism of action, adverse effects, and complications.

METHODS

Cross-sectional study. Adolescents aged 11-19 years answered a questionnaire containing questions about sexuality, knowledge, and use of EC.

RESULTS

Out of 148 adolescents who were interviewed 8% did not know about the EC. Among the sexually active, 56.7% used EC at least once. The chance of obtaining EC information with friends triples between 15-19 years old [p=0.04; OR=3.18 (1.08-10.53)]. Most used single-dose EC. They said that EC prevents 80% of pregnancy and should be used within 72 hours after unprotected sex. Only 41.2% between 10-14 years old and 82.4% between 15-19 years old know that it prevents fertilization. As reasons for using they cited: rape and unprotected sex in 58.3% of those aged 10-14 years old and 79.6% between 15-19 years old. About side effects, 58.8% of 10-14 years old and 17.6% of those aged ≥15 years old could not answer, but 60.5% between 15-19 years old mentioned nausea and vomiting. A significant portion (17.6-41.2%) believes that EC causes abortion, cancer, infertility, and fetal malformations. Over 80% of the girls agree that it can cause menstrual irregularity.

CONCLUSION

Knowledge regarding EC is not satisfactory, especially regarding its risks, regardless of the age and education of the groups evaluated. Improved knowledge may lead to greater adherence to EC and lead to a reduction in unplanned pregnancies.
