Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Women will be provided with daily Beetroot juice shots (as per study arm), membership to an Everybody Active centre close to their home, personal training sessions to tailor an exercise program to them (2 initial sessions then monthly), a wearable to track their physical activity and a home BP monitor.

12 week personalised exercise intervention with personal trainer and gym membership, fitbit

Group Type EXPERIMENTAL

Exercise

Intervention Type BEHAVIORAL

In addition to the procedures for the control group, women will be supplied with gym membership for 12 weeks, 2 initial personal training sessions to design a personal exercise program followed by monthly personal training sessions.
