Why the study?
Does normal pregnancy cause long-term changes in volume regulation hormones (ANP, renin, aldosterone) compared to age-matched controls?

14 women with normal pregnancies (no toxaemia, delivered healthy babies) and age-matched controls
Comparison
Normal pregnancy and postpartum period vs Age-matched controls
Design
Cohort
Follow-up
up to 40-120 weeks postpartum

May indicate protracted volume regulation effects after pregnancy; hypothesis-generating and should not yet change practice.
Does normal pregnancy cause long-term changes in volume regulation hormones (ANP, renin, aldosterone) compared to age-matched controls?
Normal pregnancy may have a protracted effect on volume regulation, as evidenced by persistently elevated ANP levels up to 120 weeks postpartum.
Finn et al. (1991) studied this question.
