 Yn ysgrifennid i'r sefyll, dyma'r ffordd Mena Cymari. Felly, rydyn ni oedd ymlaen i gweithio y bydiau o'r lleidwyr yng Nghymru, Mae'r lleidwyr yng Nghymru wedi gyfnodol, byn ymwyloedd yn ffodol iawn. Mae'r lleidwyr yng Nghymru yn bwysig, a'r lleidwyr yng Nghymru yn fwyloedd i'r lleidwyr i'r lleidwyr yng nghymru, ac ymwyloedd i'r lleidwyr yng Nghymru yn fwyloedd yn fwyloedd, I'm going to be talking about understanding society, actually, it's my fault, I'm the Associate Director now for Health and Biomarkers and Genesics in Understanding Society and what I'm going to do, I'm going to give you a brief overview of understanding society and then talk about recent data releases and yeah, as I said I'm a professor and I've got a PhD and everything but I can't really read and I thought I had 20 minutes for this presentation and I don't have 10 so I'm not going to talk about the omics bit which is actually my bit of understanding society, I'm going to talk about PEACH which is a data set that we've put together of younger people given what we've been talking about this morning I think focusing on that kind of, we sort of made stay where we are and then I'm going to talk about next step so it means that my presentation might be a little bit bitty just because I'm pulling out a little bits of what I'm going to be talking about rather than talking about everything. So okay, so what's understanding society, it's also known as the UK Household Longitudinal Study and we're a sample of individuals and we're representative of the UK population and we're kind of interviewing within the household, we randomly selected the sample of households, we went into building 2009 and we collect information about all of the residents in the household and we collect information about all the residents and their offspring as they get born into the survey and we follow people and we interview them every year. Our design is quite similar to a number of international household panel surveys so PSID in the US and so in Germany. We are really four different kind of surveys within the whole study so we've got a general population sample which is 26,000 UK households and as I said we've been interviewing them since 2009. We have an ethnic minority boost which is 4,000 households with one individual from an ethnic minority background and then we incorporated another household panel study, the British Household Panel Survey that had been running since 1991 and that was approximately 8,000 households, we added that from way two of the survey. We also have a set of participants and set of households that we run experiments with so we've got one, one and a half thousand households that we do a lot of methodological testing with so we test content that we can bring into the survey, we run a competition every year so if you've got interesting things that you want to test in terms of questions or want to run the experiments we can incorporate that so we have 40,000 households from waves one and two that we as I said we interviewed them every single year. We had a new immigrant and ethnic minority boost in 2015-16 which is a two and a half thousand households from the newer migrant groups so the ethnic minority boost was kind of the main ethnic groups and then we added kind of newer migrant groups so Eastern Europeans and various other groups like that. So we interview everybody in the household, all adult members of the household, we also collect data from our participants so our 10 to 15 year old participants do a self-completion and then there is also data about the children which we collect from parents and guardians and that's what I'm going to talk about a little bit later on, the PEACH survey. So those data are in the data sets but we did a bit of a review of who uses the data and what they do with it and those data aren't used as much as the rest of the data so we've done things to try and help you with that. So it's a prospective survey, we interview the same people annually and we interview new people that come into the survey. We do collect, kind of, historical things so there are retrospective elements to the study. So these are the topic areas. So I look after the biomarker genetics and epigenetics. We interviewed our participants during the pandemic so we had lockdown in March 2020 and we interviewed participants at the beginning of April and we had the data out to you at the May and we interviewed them in April, May, June, July, September, November, January 21 and April 21 so you can really see what was happening to participants during the lockdown and during the pandemic and we also carried on doing the main collection during that entire time so we have information about what was happening to all of the participants all the way through the pandemic on all of these main topics and also then those specific COVID specific things and we were also part of the COVID effort that Richard just talked about so we have serology and lots of additional information related to COVID. Now all these are the topics that we cover in the survey so education improvement, ethnicity and immigration. We have five minutes that we ask our minority participants specific questions about their experiences, we ask about family and household information, lots of information about money and finances, political and social attitudes so that's not really particularly health but for example when the Brexit question was asked we asked our participants about that so we could understand who was kind of saying which way they were voting and that sort of thing. We've got lots and lots of information on health and well-being and then this focus on young people and we also ask about transport environment so it's really wide-ranging, we don't ask everything every single time, there's lots of rolling current regions of topics throughout the survey so each year will have kind of different content. In terms of health and well-being we ask participants about their health, we ask them every year on whether they have chronic conditions, we administer the GHQ to all adults every year and have done since 2009, we ask the SF12, the short form 12 every year so we've got a really good idea of what's happening to people and what has happened to them so we had an idea that people's mental health before the pandemic or during the pandemic all the way through and now we can sort of see what's happening to them afterwards and then in waves two and three we had a clinical wave where a subset of participants were visited by a nurse and we collected lots of physiological information from them, height and weight, lung function, grip strength, we collected a blood sample from them and measured 21 different analytes, we extracted DNA, we have genetic methylation data, we've measured proteins, lots of things so there's lots and lots of different types of information, all our data are collected from participants over a two-year period, it takes two years to interview 100,000 people and we make the data available about six months after we've finished our data collection so at the end of each year we will deposit a data set for you and you can go to the archive and get it from them. So, as I said, we're thinking about mental health, what we've done today, we're going to do the participants and we went to the general health questionnaire, we've done that because it was the measure of mental health that was collected in the BHPS so the survey that was started in 1991, so for some people we have 30 years of annual GHQ measurements, we've got measures of life satisfaction in different domains, we do the Edinburgh Warwick questionnaire, the WEMWebs and we do that every year, we do that every three years or so, I've only said to waves 10, we're actually depositing wave 13 this year so we'll have that again. With the children we asked them about happiness as different aspects of their lives, so happiness is schoolwork, appearance, what happens at school, so we can capture the whole of what's happening with the children and we also run the strength and difficulties questionnaire with the children so that and we do that every other year so we don't do that every year but we've got a biannual collection of the strength and difficulties questionnaire. As I mentioned, we okay so we ask parents about their children and we collect sort of special information from the from the children at sort of age three and five and seven and when we we did a review of the what data are used from the survey and which data are not so used and we noticed that those data, the information about children at three, five and seven isn't three, five and eight, wasn't used very much so we've done a piece of work where we've kind of pulled out all of that information because it's found in lots of places because some of it's asked by parents and some of it's in lots of different bits of the survey and we wondered if that was the reason that people aren't really noticing that we've got those data there and so we've created a file for you so it's not new data it's just a new way of packaging the data so that you can follow children through the survey so we're hoping that it will facilitate researchers who are interested in child development so the file brings together information on pregnancy and early childhood into a single place so that you can go and have a look at that and what we've done is just leverage all the data on what we've got that's reported on the child and so that you can sort of sort of follow the children through so all the variables within the category are time specific and they remain constant so we've got so for example you'll have the child's birth weight which was asked of of mum or dad so you'll have that in this file and then you've got parents reporting of things like frequency of fussing or crying during infancy or frequency of reading to the children when they're a little bit older and so you can sort of follow them through and see what happens so in this file we've got a total of 303 variables and we've pulled together all of these questions at 164 questions about what's happening to children as they're going through their life so the file is structured to help you track the children's development and you can link that back to the main survey but you should be able to do lots of things within that file to help you do some interesting analyses. The cross ways are identified as a person so you can see which way things are collected and when things have been collected and so this little picture sort of goes through all of the information that's kind of there in this in this file we've called PEACH pregnancy and early childhood file and as you can probably tell I didn't do this I did this this piece of work and it's provided lots of documentation and lots of guidance on what's in the data set and how best to look at it and what we'll do is we'll we'll provide an updated version of the file every year so as the children are kind of going through the the data and then once they kind of move into the self-completed bit of the of the study they'll they'll move into the youth survey so you'll have information sort of age three five eight and then their own information at ten and and the rest of the survey so we'll we'll just keep updating as as you know people who were babies were born into the survey come through and then as they've been back so hopefully we'll it'll be a sort of a live file it's not PEACH is not part of the main stage release so we'll we'll just sort of make it available and let people know as we're updating this file. I think we've talked about the main bits of this survey that are kind of relevant to the topics that we've talked about today but don't throw away the window archive there's the our understanding society website the bits that I look after there's my email I look after the genetics and the genomic bits of the survey thank you very much
