Complications in pregnancy in women aged 35 or older

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

OBJECTIVE

To verify the frequency and factors associated with complications during pregnancy and the association between complications with premature birth and type of delivery in pregnant women aged 35 years or older.

METHODS

This is a cross-sectional study based on the records of pregnant women admitted between January and July 2012, totalling 430 pregnant women. To identify possible factors associated with complications during pregnancy, data were subjected to univariate analysis using the Poisson regression model. The chi-squared test was used to study the association of complications with premature birth ad type of delivery.

RESULTS

Complications occurred in 77.7% of the cases. Complications in pregnancy as an explanatory variable for premature birth (p < 0.001) and C-section (p = 0.002) was statistically significant.

CONCLUSION

The factors younger age, the absence of prenatal care, and the non-occurrence of morbidity prior to gestation were associated with complications in pregnancy.
