title: The incidence of pregnancy rhinitis.
abstract: The purpose of this study was to define the cumulative incidence of pregnancy rhinitis, and to study whether smoking, asthma, hayfever or month of conception are risk factors. A questionnaire was delivered during 1 year in 10 antenatal care centers in one Swedish county. Questions were asked by midwives on the ordinary check-up visits throughout pregnancy. Five centers with response rates of 70% or more, including 599 women, were evaluated. The cumulative incidence of pregnancy rhinitis was 22%. Smokers had a significantly increased incidence with a relative risk enhancement of 69%, whereas hayfever, asthma, and month of conception had no statistically significant influence on incidence. Pregnancy rhinitis was shown to appear at any time during gestation.
