Women's knowledge about Intrauterine Device and user satisfaction in Brazil: a systematic review.
Clarissa Oliveira Guimarães Lopes de Sousa, Síntia Nascimento Dos Reis, Gisele Nepomuceno de Andrade and 2 others
PMID 40434109WHAT IT FOUND
Brazilian women often lacked accurate IUD knowledge, including false beliefs about infertility, cancer and abortion, and feared insertion, while users reported high satisfaction.
Key findings
01Five included knowledge studies found misinformation about IUDs, including beliefs that the device causes abortion, cancer, infertility, ectopic pregnancy or pelvic inflammatory disease, and that it is only for women who have had children.
02In a study, 19.4% of women had correct knowledge, 41.9% partially correct and 38.7% incorrect; in another, 7.2% answered all six statements correctly, 15.3% all incorrectly, and the median number of correct answers was three.
03Seven included satisfaction studies reported high satisfaction among Brazilian IUD users, with percentages including 77.8%, 85.7%, 91%, 92.4%, 93.1%, 93.9%, 94.7%, 96.8% and 100% in different samples.

What it does not show
The included studies used different questions and scales for knowledge and satisfaction, so results cannot be compared directly. National production was concentrated in São Paulo, so the findings may not represent all regions of Brazil. No included study assessed knowledge or satisfaction in transgender men or non-binary people. The review found no Brazilian before-and-after or educational intervention studies, so it cannot show that counselling changes knowledge or uptake. The included studies were mostly average methodological quality.

The easy way to misread this
Do not read high satisfaction as proof that better information will increase IUD uptake. The review found no Brazilian before-and-after or educational intervention studies.
