Abstract

Objective: Smoking has been suggested to reduce the risk of pregnancy-induced hypertension (PIH). We have analyzed the association between smoking and risk of PIH using data from a case-control study conducted in Italy. Study design: Cases were 215 women who gave birth on randomly selected days at a network of obstetric departments and with a diagnosis of PIH, i.e. diastolic pressure above 90mmHg on at least two occasions 24h apart. Controls were 1222 women (median age 30 years) who delivered at term healthy infants on randomly days at the same hospital where the cases had been identified. Results: In comparison with never smokers, current smokers at conception were at decreased risk of PIH (odd ratio (OR) 0.7, 95% confidence intervals (CI) 0.5-1.0). The protection increased with number of cigarettes smoked per day, the OR of PIH being, respectively, 0.8 and 0.6 in women reporting
