Pre-conception Interventions to Reduce Blood Pressure Before Pregnancy (CONCEIVE 2)
18. mars 2022 oppdatert av: Imperial College Healthcare NHS Trust
The study proposes to evaluate the feasibility of a preconception intervention comprising two proven interventions for reducing blood pressure; Beetroot juice; a source of dietary nitrate which reduces BP by 8/4mmHg after 4 weeks(6); Personalised resistance and endurance exercise programme (as per CMO recommendations) which reduces BP by ~10/5mm Hg over 8-12 weeks (7).

Detaljert beskrivelse
A feasibility study will be conducted for a randomised, controlled trial of preconception interventions.
The study will advertise using posters, social media and on departmental emails at Imperial College Healthcare NHS Trust or Imperial College for women aged 18-45 planning a pregnancy at any time in the future.
The study will randomise women to 1 of 4 arms Arm 1: Exercise intervention for weeks 1-12 Arm 2: Beetroot juice for weeks 1-12 Arm 3. Exercise and Beetroot juice for weeks 1-12 Arm 4: Control group
