Avaliação da inserção de DIU na estratégia de saúde da família: um estudo de coorte

Abstract

INTRODUCTION: The copper Intrauterine Device (IUD) is a long-acting reversible contraceptive method recognized for its benefits to women’s reproductive health. Despite its advantages, its use remains limited, especially within the context of Primary Health Care. OBJECTIVE: To evaluate the continuation of IUD use among users of the Family Health Strategy in the city of Lagarto-SE, Brazil. METHODS: This study is a prospective cohort conducted with 49 women users of the Unified Health System who sought the Primary Health Unit for IUD insertion. Structured questionnaires were applied, including sociodemographic, gynecological, obstetric, and clinical follow-up data, collected at three different moments. Data were analyzed descriptively and through association tests using Fisher’s Exact Test and Cramer’s V for bivariate analysis. RESULTS: The device insertion was successful in 40 women. After 12 months, the discontinuation rate was 32.5%. The main reasons for discontinuation were IUD expulsion, increased menstrual flow, and dysmenorrhea. A statistically significant association was observed between IUD continuation and the frequency of transvaginal ultrasound examination (p=0.0043; V=0.53), indicating that regular clinical follow-up acts as a protective factor for continued use. CONCLUSION: IUD continuation is directly related to the quality of clinical follow-up and the training of health professionals in managing side effects, reinforcing the importance of strengthening counseling and follow-up within Primary Health Care.
