CODE FIRST THAT APPLIES.
(HELP )
The aim is to obtain legal marital or partnership status, otherwise known as civil
status, irrespective of any de facto arrangement. This does not necessarily mean
relationship status, because some relationship statuses such as “engaged” or “in a
relationship” are not legally recognised.
The only qualification to this aim is that you should not probe the answer
'separated'.
Should a participant query the term, explain that it covers any person whose spouse
is living elsewhere because of estrangement (whether the separation is legal or
not). Ignore temporary absences, e.g. on oil rig.
A person whose spouse/ civil partner has been working away from home for over 6
months, e.g. on a contract overseas or in the armed forces, should still be coded as
married or in a registered civil partnership if the separation is not permanent.

What is your legal marital or registered civil partnership status?1 NevMarr

household are too closely related for any to be living together in a de facto
partnership relationship.

I would now like to ask you to wear an activity monitor for the next seven days and nights,
so that we can collect information about your usual level of physical activity and sedentary
time. Physical activity is known to affect health in many ways, but it has been hard to
measure accurately, even with detailed questionnaires.
Information gathered with these activity monitors will help researchers to better understand
how physical activity affects health.
INTERVIEWER: SHOW PARTICIPANT THE ACTIVITY MONITOR AND WRIST STRAP.
The monitor is worn on your wrist like a watch. It will monitor your activity over the next
seven days and nights – whether you are sleeping, lying down, sitting, standing, walking or
taking part in some other activity such as cycling or running. You should continue to do
your normal daily activities whilst wearing the monitor.
The monitor does not have GPS technology or a camera. It cannot track your whereabouts.
The activity monitor should be worn continuously (24 hours per day) for seven days and
nights. It is waterproof, so it can be worn whilst bathing, showering and swimming.

73
As a thank you for wearing the monitor, we will email you a £5 voucher when you return the
monitor.
Please read this leaflet, it explains more about what is involved.

INTERVIEWER: GIVE THE PARTICIPANT THE ACTIVITY MONITOR LEAFLET AND
ALLOW THEM TIME TO READ IT AND ASK YOU ANY QUESTIONS. IF THEY ARE
UNABLE TO READ THE LEAFLET, GO THROUGH IT WITH THEM TO ENSURE THEY
FULLY UNDERSTAND THE TASK.NOTE THE COLOUR OF THE STICKER AND THE

We would like you to help us with the second (and final) stage of this study. This is a visit
by a qualified nurse to collect some medical information and carry out some
measurements, including a blood sample. These measurements are important as they
complete the information you give us in the diet recalls. The nurse would like to contact you
to explain more about what is involved and answer any questions you have.

STAGE 2 LEAFLET, APPROPRIATE FOR THEIR AGE.”}
{IF Method = Tel or Video: “INTERVIEWER PLEASE CHECK THAT THE PARTICIPANT
HAS RECEIVED THE STAGE 2 LEAFLET IN THEIR INTERVIEW PACK. PLEASE ASK
THE PARTICIPANT TO READ THROUGH THE LEAFLET”}

IF ASKED FOR DETAILS: For example, the nurse, with your agreement, will take your
waist and hip measurements, ask if you are willing to provide a blood sample and ask
about prescribed medications. We cannot get the information the nurse collects from any
other source.
All aspects of the nurse visit are voluntary.

THEIR ELIGIBILITY.

1 Yes
2 No

IF (NursExclChk = Yes) THEN

IF (NursExclChk = No OR Unsure) THEN
NursInt2
IF ASKED: If you are eligible the nurse will ask if you and/or your child are willing to provide
a small blood sample. Blood tests can give us very important information about nutritional
health that we cannot get in any other way, and about the ways in which our body benefits
from the food we eat. If you wish, we will also send you and/or your GP the results of some
of the tests carried out on your sample.
The nurse will take no more than 12-35ml (2 tsp- 7 tsp) of blood. The amount is different for
adults and children (smaller amounts are taken from the youngest children).
INTERVIEWER: Always mention the nurse by name (if known).
If participant is unsure/hesitant then code '3 Agreed but hesitant' here. The nurse will still
contact the participant but will be aware that the participant was unsure about the nurse
visit.
Press for help about the nurse visit
I see my doctor all the time…
We don't have access to your records and therefore we can't get this
information any other way, so our nurse comes to visit you personally.

Will I have to give blood?
No, the nurse will ask for written or verbal consent before any
measurements. You don’t have to do anything you don’t want to. We will
handle your data in accordance with data protection legislation and we take
great care to protect the confidentiality of all information and samples
collected.
I haven't time…
The nurse can come at any time to suit you, they will call to see when best
suits you.
Why is it necessary? …
You have given us lots of really useful information, but because this is a
survey about health, there are certain things interviewers can't do (like take
blood samples) so we have a nurse visit to get this information. The blood
sample is important as it tells us information that we can’t get from the
interview questions.

As part of this study, we would like all participants to complete an online food record called
Intake24. [you/child’s name] will be asked to describe everything you/they had to eat and
drink the day before. We call this a 'recall' as you will be recalling what you ate the day
before. We'd like everyone who is taking part in Intake24 to complete one recall today {If
Method = F2F: “while I am here”} and then three more times in the next few weeks. I will
explain how it works and will answer any questions you might have. It's easy to complete
and should only take around 20 minutes each time. Everyone who completes a recall today
will receive a £5 shopping gift card and a further £20 gift card after completing all four
recalls and a physical activity questionnaire. At the end of completing all of the four recalls
[you/your child’s] can also get automatic detailed feedback on [your/your child’s] diet if you
wish.
INTERVIEWER: ADVISE PARENTS THAT THEY ARE ABLE TO HELP CHILDREN.

Thank you for your patience. It looks like we won’t be able to complete your first recall
at this moment due to technical difficulties. If you agree, you can complete the recall
over the phone with one of my colleagues from the MRC Epidemiology Unit in
Cambridge. This will take up to 45 minutes to complete.
I will need to pass on your name and telephone number so that they can phone you to
complete the recall with you.
IF ASKED: We will only pass on the participant’s name, (IF APPLICABLE the
parent/guardian’s name), the participant’s age group so it is clear who should complete
the questionnaire (i.e. parent/guardians complete questionnaires for younger children),
participant serial number, email address and/or phone number.

We will also send you a food atlas which will help with estimating portion sizes. Are you
willing to complete the recall over the phone and for your contact details to be passed
onto MRC Epidemiology Unit for this purpose?

IF ASKED
The food atlas is an A4 book with photos of different foods and portion sizes that will
help you estimate what you ate and drank while completing the recall over the phone.
