CASTILLO CASTRO, Evert et al. Cervicometry less than or equal to 30 mm as a predictor of preterm birth in Peruvian pregnant women. []. , 18, 1, pp. 96-103.   02--2020. ISSN 1727-897X.

Foundation:

The threat of preterm birth is a situation that requires a useful and objective test to rule out or confirm the suspected diagnosis.

Objectives:

to evaluate cervicometry less than or equal to 30 mm as a predictor of preterm birth in Peruvian pregnant women with this risk.

Method:

a descriptive study, which included 100 women diagnosed with a threat of preterm birth, treated at the Víctor Lazarte Echegaray Hospital, Peru. They were grouped according to the exposure factor: 50 women with cervicometry ≤ 30 mm and another 50 with cervicometry> 30 mm, to assess the occurrence or not of preterm labor. Bivariate and multivariate analysis with a value of p <0.05 was applied; and sensitivity, specificity and predictive values were calculated.

Results:

the frequency of preterm birth was 46%. There were differences between the groups regarding the occurrence of preterm birth and delivery within seven days of admission. The risk factors detected were: history of preterm birth (RR = 1.48; 95% CI: 1.13-1.95) and cervicometry ≤ 30mm (RR = 3.81; 95% CI: 2.06-7.04). Cervicometry ≤ 30 mm showed sensitivity of 80.43% and specificity of 75.93%.

Conclusion:

Cervicometry ≤ 30mm is a risk factor for preterm birth in women with this threat; and it can be used as a discriminatory test in those with this condition, regardless of presenting a history of a similar event.
