Frecuencia de control prenatal inadecuado y de factores asociados a su ocurrencia.

Objective: To determine the frequency of patients with inadequate prenatal care (PNC) and the factors associated with this event. Material and methods: A cross-sectional, descriptive study and data was obtained interviewing the mothers, reviewing clinical records and Maternal Perinatal Card between August 2010 and January 2011 at the Hospital Nacional Cayetano Heredia. We defined inadequate PNC as the failure of the minimum number of visits and schedule proposed by the Ministry of Health. We compared epidemiological, maternal and socioeconomic factors in groups with adequate PNC and non-adequate PNC. Results: We included 384 women, 66.05% received 6 or more prenatal controls and only 7.36% had an adequate PNC. 145 women had her first PNC before the 12 weeks of pregnancy. The factors with more frequency in the non-adequate PNC was a maternal parity more than 2 (p=0.02) and a non-planning pregnancy (p=0.003). Conclusions: The rate of non-adequate PNC was high. Having a maternal parity more than 2 and a non-planning pregnancy were associated with non-adequate PNC. [ABSTRACT FROM AUTHOR]
