Methods and analysis

Sample size: 3000 patients are needed to demonstrate a significant difference between the groups.

Recruitment

From hospital out-patient clinics around the UK.

Questionnaires

Four types of questionnaires (see below) are issued, once every year for 5 years.

Informed Consent

Obtained from patients after discussion and receiving an information sheet.

Plenty of time is allowed for questions and patients are encouraged to ask as many as they wish.

Blood & Urine

Samples are taken once every year for 5 years.

Blood and urine samples are analysed for a number of markers such as:

  • Phytoestrogens
  • Phytochemicals

Lifestyle

This is assessed using a fully validated questionnaire which asks a variety of questions about all aspects of life: past medical history and current treatment, job status and educational achievements, smoking, alcohol consumption and many more. This information allows us to construct a complete lifestyle profile of the patient at recruitment. The lifestyle follow-up questionnaire is issued at subsequent visits to identify any changes in the lifestyle and general health of the individual over the following years.

General health questionnaire

This questionnaire asks about how anxious (or not) the individual is feeling and so allows us to assess levels of anxiety and certain elements of stress. These will be analysed using General Health Questionnaire standards.

Food frequency questionnaire

This allows documentation of the frequency of intake of foods over 1 year. It allows us to calculate average intake of food groups and to identify any changes in the nutrition of the individual over a period of time.

7-day food diary

This enables us to calculate exact dietary intake over 1 week as participants are asked to list all food items consumed and briefly describe the preparation of their meals.
