Reproductive planning is a widespread strategy worldwide, focused on the promotion of care
focused on conception and contraception. Contraception involves ensuring the appropriate
choice and management of the contraceptive method, and is developed by professionals in
different areas of care. For an informed choice, tools to support health education are important.
The aim of this research was to evaluate the effects of an educational intervention on progestin-
only pills on the knowledge of pregnant women. This is a quantitative, before-and-after study,
with application of individual educational intervention with the participants and questionnaires
for identification and evaluation of knowledge before and after the intervention, developed
between April 2021 and April 2023, in the Primary Care Network of the city of Palmas - TO.
The population participating in the research was composed of pregnant women and data
collection was developed through four phases: mapping and choice of participants through
medical records analysis; individual application of socioeconomic and reproductive
questionnaire and Knowledge Assessment Questionnaire before the intervention; Individual
Educational Intervention with the aid of educational materials; and Application of the
Knowledge Assessment Questionnaire in participants afterwards. Quantitative analysis was
performed using statistical software validated for health research, evaluating categorical and
numerical variables. The outcome variable is level of knowledge, analyzed in a categorical,
nominal, dichotomous way. The comparison of variables before and after was done by applying
the McNemar test. The project complied with ethical principles, according to protocol number
5.829.489 of the Ethics Committee. The mean age of the participants was 27.6 ± 5.9; the mean
income was R$2709.42 ± 2349.35; most of them had incomplete high school education, 68
(60.2%); 82 (72.6%) women declared themselves white and 80 (72.1%) were in a stable
relationship with a fixed partner. In the evaluation before the intervention 85 (74.6%) pregnant
women were classified with unsatisfactory knowledge and in the evaluation after the
intervention, 104 (93.7%) were classified with satisfactory knowledge. After describing the
socioeconomic and reproductive profile of the pregnant women, it was found that there was no
statistical association between these characteristics and the level of knowledge before and after
on the object of study, however, from the analysis of the variables by the McNemar test, it was
evident that the gain in knowledge of the participants, is statistically associated with the
individual educational intervention with the booklet "Educating in prenatal care" (p<0.001). It
is concluded that the educational material contributed to the increase in the level of knowledge
of pregnant women about the pill.
