ABSTRACT
Objetive The aim of this study was to determine the relationship between being smoker, ex-smoker or passive smoker and the risk of developing a placental Grannum-grade- III and the interval of time necessary between stop smoking and becomepregnant. Material and

methods:

A retrospective case-control analysis was performed for women with singleton pregnancy that had ultrasound in the third trimester, establishing two groups according to the classification of placental aging purposed by Grannum Grannum grade III and Grannum grade I-II. In both groups,maternal characteristics and perinatal outcomes were studied, and also the risk of placental premature aging in pregnant smokers, ex-smokers and passive smokers.

Results:

Being smokers (p < 0.01) or suffer from a hypertensive disorder (p = 0.01)is associated with a higher risk of premature placental aging. Smokers who quit during early pregnancy and passive smokers behave like smokers,withno significant differences between them. We have also studied ex-smokers and the period of time between quit and became pregnant and the findings show a decrease of six times risk of to develop a Grannum grade III placenta for women who retires from smoke more than a year beforepregnancy.

Conclusions:

The main causes of developing a premature aging of the placenta are being a smoker and developing a hypertensive disorder. Smoking cessation should occur before becoming pregnant, ideally more than 18 months earlier, in order to avoid placentalabnormalities
RESUMEN

Objetivo:

el objetivo de este estudio fue determinar la relación entre ser fumadora, exfumadora o fumadora pasiva y el riesgo de desarrollar una placenta Grannum grado III y el intervalo de tiempo necesario entre dejar de fumar y quedarembarazada. Material y

métodos:

se realizó un análisis retrospectivo de casos y controles para mujeres con embarazos únicos a las que se realizó una ecografía en el tercer trimestre, estableciendo dos grupos según la clasificación de envejecimiento placentario propuesta por Grannum Grannum grado III y Grannum grado I-II. En ambos grupos, se estudiaron las características maternas y los resultados perinatales, así como el riesgo de envejecimiento prematuro de placenta en mujeres embarazadas fumadoras, exfumadoras y fumadoraspasivas.

Resultados:

ser fumador (p < 0,01) o padecer un trastorno hipertensivo (p = 0,01) se asocia con mayor riesgo de envejecimiento prematuro de placenta. Las fumadoras que abandonan el hábito al inicio del embarazo y las fumadoras pasivas se comportan como fumadoras, sin diferencias significativas entre ellas. Asimismo se ha estudiado a las exfumadoras y el período de tiempo entre dejar de fumar y quedar embarazada y los hallazgos muestran un riesgo seis veces menor de desarrollar una placenta de grado III de Grannum en mujeres que abandonaron el hábito más de doce meses antes de quedar gestantes.

Conclusiones:

las principales causas de desarrollar envejecimiento prematuro de placenta son ser fumadora y desarrollar un trastorno hipertensivo. El abandono del hábito tabáquico debe producirse antes de quedar embarazada, idealmente más de 18 meses antes, para evitar anormalidades placentarias
