Abstract

Objective: Analyze the influence of socio-demographic and maternal factors on the occurrence of spontaneous and missed miscarriage.

Method: A descriptive epidemiological study that analyzed socio-demographic, obstetric, and nursing variables for the period 2019-2024, collected in electronic records of a hospital in the northwest of Paraná, and analyzed using the Pearson chi-square test.

Results: Of the 436 cases, predominance was identified until the 12th week of pregnancy (82.2% of missed miscarriage and 67.7% of spontaneous abortions). Abortions were significantly more prevalent in women with up to eight years of study and those with higher educational levels. Adolescents and women aged 35 or older were more vulnerable to missed miscarriage, while those aged 16 to 34 were more vulnerable to spontaneous abortion.

Conclusion: Maternal age and schooling influence the types of abortion, evidencing sociodemographic inequalities that permeate the reproductive process. Public policies that broaden access and qualify reproductive care in the Single Health System are necessary.
