RESULTS
Of the 4,851 PRIDE Study participants who completed the first follow-up
questionnaire in the study period, 1,516 (31.3%) completed the
medication diary (Figure 1). Among participants with a completed
medication diary, 1,275 (84.1%) gave permission to request pharmacy
records. Pharmacy records including start and stop dates of medication
were obtained from 816 participants (64.0%). Characteristics of the
study population and excluded PRIDE Study participants are shown in
Supplemental Table 2.
According to the pharmacy records, 235 (28.8%) participants used at
least one of the selected medications during the 6-weeks diary period.
These participants were slightly older, more often had a
low/intermediate level of education, a net household income of
<\euro3,500 per month, and a chronic condition, had a higher
pre-pregnancy BMI, and were more likely to smoke during pregnancy
compared to participants who were not dispensed medication in the diary
period (Table 1).
