Redmine Support #2076 (Feedback): Issues with xx_hadcvvac variables in COVID-19 data collectionhttps://iserredex.essex.ac.uk/support/issues/20762024-03-13T21:01:15ZLaura L
<p>Good evening,</p>
<p>I am currently analysing data from the <em>xx_indresp_w</em> datasets of the COVID-19 data collection, specifically from wave 9 (ci), wave 8 (ch) and wave 7 (cg). From the documentation, the questions <em>xx_hadcvvac</em> (about having received the COVID-19 vaccine in each survey wave) should be asked to respondents that have not already answered that they received 1 or 2 doses of vaccines in previous months (answer codes 1 and 2). However, by cross-tabulating the answers to the <em>xx_hadcvvac</em> questions for wave 7 and 9 for respondents present in wave 9 and 7 (left-joining the datasets by respondent ID <em>pidp</em>, i.e. matching all respondents in wave 9 with those that were also in wave 7):</p>
<p>table(ci_hadcvvac = wave_9$ci_hadcvvac, cg_hadcvvac = wave_9$cg_hadcvvac)</p>
<p>with <em>wave_9</em> the left-joined dataset, I obtain the following table:</p>
<pre><code>cg_hadcvvac<br />ci_hadcvvac -9 -8 -2 1 2 3 4<br /> -8 0 10 0 133 9 492 4835<br /> -2 2 0 2 0 0 0 4<br /> 1 0 0 0 4 1 1 133<br /> 2 0 3 1 <strong>1663 116</strong> 36 2538<br /> 3 0 0 0 0 0 1 5<br /> 4 0 0 0 2 0 3 322</code></pre>
<p>As you can see from the numbers in bold (took as examples), there are some respondents vaccinated in wave 7 that appear to be asked the question again in wave 9. Am I missing some information?</p>
<p>Thank you very much in advance for the support.</p>

<p>Hi,<br />Do you have any estimate when the wave 16 biological data is likely to be released?

<p>I am interested in looking at BMI across different years but it seems this variable (or weight and height which would allow for BMI to be calculated) is only present in wave 1, is this true? In the understanding society webpage it says “A range of bio-medical measures were collected from around 20,000 adults, which included blood pressure, weight, height” but am struggling to find them, are they available anywhere?

<p>In the cv_indresp dataset (COVID-19 survey), there are three variables (i_outcome, j_outcome, k_outcome) referring to three survey waves of the main survey. They are supposed to indicate the completion status of each of these main survey wave for each respondent. However, I cannot find I clear indication about the values coding. How should I interpret the different values of the w_outcome variables?</p> Support #2039 (Resolved): Household identifier in Understanding Society COVID-19 Survey Waveshttps://iserredex.essex.ac.uk/support/issues/20392024-01-24T10:07:56ZLaura L
<p>I have a question about the use of the household identifiers (i_hidp, j_hidp, k_hidp) in the Understanding Society COVID-19 data. From what I understand from the user guide, j_hidp and k_hidp both refer to interviews made in 2019, in wave 10 and 11 of the main Understanding Society survey respectively. So, each respondent in the COVID-19 survey should either have j_hidp, and "-8" (inapplicable) in k_hidp, or viceversa. However, within the same COVID-19 survey wave respondents have both, except for few missing values (around 2-3 per identifier, code "-9"). Is there something I am not understanding? Shouldn't the two identifiers be alternative?</p> Support #1997 (Resolved): Issues using variable w_fimnnet_dv in COVID-19 dataset jk_wavehttps://iserredex.essex.ac.uk/support/issues/19972023-11-30T15:21:33ZMhairi Webster
<p>Hello,</p>
<p>I am currently analyse the COVID-19 dataset, including the jk (2019) wave. I want to include a variable for income (jk_fimnnet_dv) but it appears to not be available in the jk wave. Could you let me know if an income variable is included in the Jk (2019) wave?</p>

<p>I received access for the dataset EGAD00010001521 through the Sanger Institute (link to the dataset: <a class="external" href="https://ega-archive.org/datasets/EGAD00010001521">https://ega-archive.org/datasets/EGAD00010001521</a>). This dataset constitutes DNA methylation samples from Understanding Society Study. We were planning to use it for our study as control data. However, the data is processed by a normalization method which is not suitable to my analysis. I would like to ask if it is possible to have access to the raw data (IDAT files). If possible, could you inform me about the steps I should take?</p> Support #1932 (Resolved): Caring Module Covid Study Wave 2https://iserredex.essex.ac.uk/support/issues/19322023-07-05T14:36:13ZLaurence Rowley-Abel
<p>Dear UKHLS team,<br />In the telephone interview version of the second wave (May 2020) of the Covid study, the caring module contains a question carechange2 (page 30 of the attached questionnaire). This asks: "Thinking back to earlier this year, before the outbreak of the coronavirus pandemic. Did you provide help or support to family, friends or neighbours who do not live in the same house/flat as you then?" with the response options of "Yes" and "No". However in the data file cb_indresp_t.dta, the variable cb_carechange2 does not appear to have responses relating to that question, and instead appears to contain an indicator of whether the respondent mentioned the second response option in the previous question (carechange1), as there are variables cb_carechange1, cb_carechange2, cb_carechange3, cb_carechange4, cb_carechange5 each containing "Mentioned" or "Not mentioned" responses for the five response options from the carechange1 question. Additionally, I think that the variable cb_carechange2 does not correspond to the question carechange2, as the question was only asked to respondents who said they did not provide care in the last four weeks (caring==2), but in the data file the respondents with valid answers for cb_carechange2 all said they did provide care in the last four weeks (caring==1). Would you be able to advise me what variable contains the responses to the carechange2 question?</p>
<p>Many thanks.</p>

<p>To who it may concern,</p>
<p>I am currently using UKHLS covid wave 7,8,9 to conduct research. In the questionnaires, jbsoc variable exists in these three waves, but in the data file, I can only find it in wave 8.</p>
<p>Also, there is no derived industry variable, and I found the question in wave 8 is checking the industry in wave 7 and in wvae 9 is checking either wave 7 and wave8. In this case, can I get the information by firstly derived one industry variable for wave 8 and then another one for wave 9.</p>
<p>The last part is regarding the marriage/cohabitation status. Can I generate a variable based on household relationships? But what if they get married but not living together? According to the way UKHLS suggests finding a partner or spouse, does it mean we can only identify a spouse or partner for couples living together that have the same household address?</p>
<p>Would you mind helping me with this issue, please?</p>

<p>Hi,</p>
<p>We have granted access to the gwas data through EGA (through WTSI) after the process of signing an agreement (dataset EGAD00010000890). However, the data-set we granted access to contains illumina's IDATS files with the signal intensities making it time-consuming to process them. Is there anyway we can get this data in plink format?</p>

<p>I am analysing data from the Understanding society Nurse Health assessment. To evaluate kidney function I aim to use creatinine values from the blood samples and a measure of creatinine production (essentially muscle mass). The sunbjects underwent bioimpedance assessment of body composition and the nurse noted the body fat percentage which I find in the documentation and in the variables. Since the device used (Tanita scale) also present other measures like total body muscle mass, lean body mass, total body water and possibly body cell mass I am curious to know if these data also have been recorded?</p>
<p>Finding a better measure for muscle mass than subtracting fat mass from body weight to get lean body mass is essential for our study. The key concept of our current research is assessing kidney function without using the estimated GFR from creatinine to be able to adress some possible confounders of the association between estimated GFR and adverse outcomes.</p>
<p>I would much appreciate any guidance you can provide in this matter.</p>

<p>I am interested in using the wave 2 main interview data linked to the nurse assessment data on biomarkers for this sample only (i.e. I am only interested in the GPS sample, not combining with the BHPS sample who had their nurse assessment after wave 3). I understand from the Nurse Assessment user guide that I should use the weight variable 'b_indnsus_xw' for this type of analysis. However I cannot seem to find this variable in the wave 2 main data or the nurse's assessment data. Would you be able to advise where it can be found?

<p>Dear Understanding Society Team,</p>
<p>In the nurse visit file for wave 2 individuals, b_indsamp_ns, there are 3827 records with nurse interviewer ID 9999 (b_nsintnum). It looks as though this ID was applied to those who refused the nurse visit at the CATI stage or were out of scope/ineligible at CATI, but the numbers do not quite match up (e.g. some households and individuals recorded as CATI refusals have nurse IDs that correspond to nurses in the xivdata_ns file).</p>
<p>Please could you confirm the criteria for applying nurse interviewer ID 9999?</p>
<p>Thanks,</p>
<p>Fiona.</p>
