Differences in knowledge and attitudes toward the intrauterine device: Do age and race matter?

Abstract

The intrauterine device (IUD) is highly effective birth control, but US IUD usage lags. Barriers to usage, including patient attitudes and lack of knowledge, are not well-characterized. This study sought to investigate how attitudes and knowledge about IUD vary by age and race. A survey was distributed to all women in the outpatient obstetrics and gynecology office of a large, urban, academic medical center in Philadelphia. Exclusion criteria included inability to read English or age less than 14 years. Surveys queried participant demographics, knowledge about and opinions of IUD. The authors performed exploratory bi-variable analysis using t tests and chi-square testing to determine which outcomes differed by age and race. For those differing significantly, the authors performed regression analysis to assess for confounding by other factors. Of 1366 women approached, 521 completed the survey (38% response rate). After controlling for confounding, only responses to the statement 'Hormonal birth control is safe and effective' differed significantly by age. Knowledge about IUD did not differ significantly by race, but black women were significantly more likely to perceive that they had insufficient knowledge about IUD compared to white women (odds ratio [OR]: 1.91; 95% confidence interval [CI]: 1.06-3.46). Black women had a more negative opinion of IUD safety (OR: 5.0; 95% CI: 2.35-10.66) and reliability (OR: 5.5; 95% CI: 2.20-14.13) than white women. Attitudes and knowledge about IUD do not differ significantly by age. While knowledge about IUD is similar between races, black women may have more negative opinions of IUD.
