RESUMO
BACKGROUND: Preeclampsia is one of the most frequent and serious complication of pregnancy characterized by systemic perfusion reduction generated by vasospasm and activation of coagulation systems. OBJECTIVE: To evaluate the association between preeclampsia sociodemographics and obstetrics antecedents. MATERIAL AND METHOD: An unmatched case-control study was carried out in which all the clinical registries of patients with preeclampsia (cases: n = 196) assisted in the period 2003-2007 in the Hospital Civil of Culiacan, Sinaloa State of Mexico were analyzed. As controls the clinical registries of patients assisted during the same period were selected at random but that they didn't show up preeclampsia (n = 470). The association of preeclampsia with socioeconomic level, tobacco use, alcohol use, gynecologic and obstetric antecedents (sexual partners, pregnancies, deliveries and abortions number, prenatal control, contraceptive method) and previous pregnancy with preeclampsia were analyzed. RESULTS: There were not association between tobacco use (OR: 3.05; 95% CI: 0.81-11.48), beginning of sexual activity (p = 0.1509), number of sexual partners (OR: 1.23; 95% CI: 0.83-1.83; p = 0.3009) and sexual cohabitation less than 12 months (OR: 0.90; 95% CI: 0.63-1.27). The alcoholism (OR: 5.77; 95% CI: 1.48-22.53), socioeconomic level (p < 0.05), pregnancy previous with preeclampsia (RM:14.81; 95% CI: 1.77-123.85; p = 0.0006) were associated with preeclampsia. There were differences in the use of the contraceptive method between groups (p < 0.005). CONCLUSIONS: Preeclampsia was significantly associated with the alcoholism, low socioeconomic level and pregnancy previous with preeclampsia.
