Abstract
We obtained our information from the Aberdeen Maternal and Neonatal Databank for all singleton deliveries to city residents aged at least 20 years during 1988-97; totalling 23 806 deliveries.3 We used logistic regression to obtain crude odds ratios for delivery by caesarean section among older women (age categories 30-31, 32-33, 34-35, 36-37, 38-39, and 40 and over) compared with a reference group of women aged 20-29 years. Primiparous and multiparous women were analysed separately, as were elective and emergency caesarean sections. We investigated the potential confounders of the association between age and outcome, and we also checked for any evidence of effect modification with the same variables—maternal sociodemographic characteristics and obstetric history.Keywords
