HypertensionCohort study
Maternal intake of dietary protein from plant and animal sources and development of pharmacologically treated hypertension within 10 years after pregnancy
- Prospective cohort study
- registry-linked
- multivariable Cox models
Authors' conclusion
The findings suggest that intake of protein from dairy sources is inversely associated with hypertension, while protein from red meat is positively associated with developing hypertension up to ten years after pregnancy.
Study context
- Population
- Norwegian mothers in MoBa (recruited 2004–2008) without pre-pregnancy hypertension
- Participants
- 59,967 mothers
- Exposure
- Quintiles of dietary protein intake from plant and animal sources
- Outcome
- Pharmacologically treated hypertension (antihypertensive medication use >90 days after delivery)
- Follow-up
- Up to 10 years after delivery
