RESULTS
Demographics All the demographic characteristics of the teenagers versus the reference women differed significantly, except for pre-existing diabetes (table 1). Pregnant teenagers were more likely to be single, live in a rural area, smoke and be diagnosed with misuse of alcohol or drugs during pregnancy. Pre-existing hypertension was more common in the reference group. All groups showed a good mean number of visits to an antenatal clinic (table 2). However, teenagers started their prenatal care significantly later in pregnancy. All teenage groups were also more likely to show a signifi- cantly lower attendance rate.
