Summary of Examination and Questionnaire Changes in 2021-2022



TABLE OF CONTENTS














MEC Examination Change Summary

In 2021-2022, the NHANES Examination consist of the following components:

  • Anthropometry - Body Measures

  • Standing Balance

  • Dual Energy X-Ray Absorptiometry (DXA)

  • Blood Pressure Measurement

  • Liver Elastography

  • Urine collection

  • Venipuncture

To promote the safety of survey participants as well as field staff in the context of the pandemic, for the 2021-2022 cycle, NHANES program will make the following changes to the examination components to shorten the face-to-face contact in the Mobil Examination Center (MEC), and to preserve the essential data collection needed in monitoring the nation’s health.

  • For the Standing Balance Component, all nonessential subcomponents (i.e., binocular static visual acuity, dynamic visual acuity, contrast sensitivity and lensometer) will not be conducted so that the length of the component and overall time in the MEC is reduced. Additionally, belts worn by participants and used to assist the MEC staff to grab a participant in the event they started to lose their balance, will not be used. It was determined that their use was very limited in 2019-20 and the subject matter experts have suggested other methods to achieve the same purpose if a participant starts to lose the balance. Reasoning for this change was to reduce the number of touch points between MEC staff and participants.

  • Dual Energy X-Ray Absorptiometry (DXA) component will be modified to drop the osteoporosis assessment of the spine and femur. Reasoning for this change is to reduce the length of the component and overall time in the MEC.

  • Measurement of resting pulse rate will be discontinued for children 0-7 years. This change is made to reduce the overall MEC exam time, and in account of the relatively lower utility of this data item for this age group. Resting pulse rate will still be measured for survey participants 8 years and older as part of their blood pressure measurements. Blood pressure has always been measured among participants 8 years and older. No changes anticipated for this protocol or the target age group in the 2021-22 cycle.

  • While the exam protocol for venipuncture/phlebotomy component will remain the same, improved talking points for children and their parents, and additional distraction and pain management techniques will be implemented to improve the phlebotomy response rates for children aged 1-17 years old. Blood will be collected for COVID-19 serology tests. This will provide data for national estimates of COVID-19 immunity. In addition, this information can be used in conjunction with other exam and lab data collected to further assess the effect of COVID-19 on the nation’s health. There are other changes in lab analytes planned for the 2021-22 cycle as well. Complete lists of these changes are provided in Attachment 6a. Lab analytes from previous cycles of NHANES are found in Attachment 6b.



  • Audiometry and the Words-In-Noise components will not be conducted for safety reasons. The exam is required to be conducted in a relatively small soundproof booth where the MEC staff must spend time with the participants to set-up the earphones and look inside the participant’s ear. Afterwards, the participant was left in this booth with door closed through the exam. Therefore, it was decided to not conduct this exam during this data collection period.

  • The Cognitive Function component was conducted as part of the MEC Interview. In 2021-22, we will not conduct this exam. The target group for this exam is participants 60 years and older, and the exam requires the participant and the MEC staff to interact face-to-face to complete the multiple domains of the test. Individuals 60 years and older are at higher risk for severe illness from COVID-19. Given the situation of the pandemic, it was deemed best not to conduct this exam to reduce the face-to-face contact and overall time for this group of participants.

  • The Oral Health examination will not be conducted for safety reasons. NHANES is a health study, not conducting an exam during which the MEC dentist is looking and touching the inside of a participant’s open mouth seems prudent in the context of pandemic.

  • HPV swab collection in both males and females will not be conducted to reduce the time of the overall survey for participant and MEC Staff safety.

Traditionally, each MEC examination session was scheduled with 10-12 participants. To preserve proper social distancing, fewer participants will be scheduled in each MEC section so the person/space ratio in the MEC is consistent with CDC guidance. Additional sanitary protocols will be implemented in the MEC to clean the equipment and contacting surfaces after the completion of each individual exam and each exam section.

Screening for COVID-19 will take place prior to participants and visitors (i.e., interpreters, consultants, contractors, etc.) entering the NHANES Mobile Examination Center (MEC). The screening protocol will follow the most updated CDC guidance. Participants and visitors will receive a COVID-19 antigen test and be asked about any COVID-19 symptoms and/or contacts with individuals diagnosed having COVID-19. Temperatures via thermal thermometers will also be taken. Those testing positive, with symptoms, or who have had contact to individuals with COVID-19 will not be allowed to enter the MEC and their visits will be rescheduled if possible. Additionally, those testing positive will receive and letter informing them of this result as well as CDC informational fact sheets that detail how not to spread the virus (Attachment 14L).

All screening tests, questions and temperature checks will be completed by NHANES clinical staff and be done in a large canopy tent outside the MEC. This tent will be large enough to allow tables/chairs with social distancing inside. Upon arrival to the MEC location, all participants that arrive via car will be asked to remain in their cars until called by MEC staff to come to the tent for check-in. This will enable safe social distancing and allowing the staff to help check in participants that arrive via public transportation or ride-hailing services (i.e., taxi, Uber, Lyft). Each participant or family members will be screened at a time with sanitizing occurring after each screening. Everyone will be advised mask wearing is mandatory and will be provided with a mask or will be allowed to wear their own mask if they choose.

Questionnaire Change Summary

The NHANES interview consists of the following major components:

  1. Household Screener Questionnaire (determines eligibility) (SCQ)

  2. Household Family Relationship Questionnaire (SFQ)

  3. Household Sample Participant Questionnaire (HPQ)

  4. Household Family Questionnaire (HFQ)

  5. Mobile Examination Center (MEC) Interview (CAPI and ACASI)

  6. Dietary Interviews (24-hour Dietary Recall, Post-Dietary Recall Questions, and 30-day Dietary Supplement Use)

  7. Special Follow-Up Questionnaire: Flexible Consumer Behavior Survey (FCBS) Phone Follow-Up Supplemental Module

To promote the safety of survey participants as well as field staff in the context of the pandemic, for the 2021-2022 cycle, NHANES program will make changes to the interview mode for the following instruments to reduce face-to-face contact:

  • For the Household Screener Questionnaire (SCQ) and Family Relationship Questionnaire (SFQ), a multi-mode approach will be implemented so the respondent will have the option to complete the questionnaires using a self-administered web instrument, a self-administered paper questionnaire, a toll-free telephone number to participate in an interviewer-administered telephone interview, or having an in-person interview with an interviewer at their residence. Use of hand card will be eliminated for administering screeners to reduce the touch points with in-person interview.

  • In previous NHANES, the Household Sample Participant Questionnaire (HPQ) and Family Questionnaire (HFQ) were administered by field interviewers as in-person interviews. In 2021-2022, these interviews will be conducted via telephone, unless the participant does not have access to a phone. Appointments will be scheduled with potential participants after their eligibilities are confirmed with SCQ.

  • Mobile Examination Center (MEC) Interview will mainly be conducted using the Audio-Computer-Assisted Self-Interview (ACASI) system so participants can complete the questionnaire on their own using the touch screen on the computer. Only limited questions will be asked by a clinician or and phlebotomist in the MEC using the Computer-Assisted Personal Interview (CAPI) system.

  • Similar to previous NHANES, two Dietary Interviews (24-hour Dietary Recall, Post-Dietary Recall Questions, and 24-hour Dietary Supplement use) will be collected for each participant. However, instead of having the first dietary interview collected in-person by an interviewer in the MEC and the second one collected via telephone, both dietary interviews will be collected via telephone in 2021-2022. At the end of their MEC visit, participants will be asked to take part in the dietary interview and schedule a telephone appointment.

With most of the interviews developed to be conducted via telephone or self-administered ACASI, a significant reduction in interview content is planned for the 2021-2022 data collection so the length of the interviews is feasible for the designed interview modes with reasonable burden to the respondents. The NHANES staff conducted a thorough review of the questionnaire content and made changes to focus on retaining questions that are directly related to the interpretation of exam or lab data collected in the survey and relevant to assess the pandemic’s effect on health topics. As a result, the household HPQ and HFQ retained 343 questions from the original 769 questions in the previous cycle. There are 14 new questions added in various sections in HPQ and HFQ. In addition, a new section was added in HPQ to ask 14 COVID infection and testing related questions that are essential in the interpretation of laboratory results collected in the survey on COVID serology. There are 109 questions retained from the 198 questions in the MEC interview questionnaire in the previous cycle. The descriptions of these changes are included in the tables below.



Description of changes

Household Screener Questionnaire (SCQ) and Family Relationship Questionnaire (SFQ)

Component Name

Descriptions

Screener Module #1 & #2 (SCQ and SFQ)

    • Three instruments (i.e., web, paper, and in-person CAPI) were developed to administer both SCQ and SFQ. While the information collected through each instrument is the same, each instrument contains instrument-appropriate probes and display instructions to ensure the operational feasibility.

    • Use of hand card will be eliminated for administering screeners to reduce the touch points with in-person interview.

    • Added questions (SCQ.NEW0a/SCQ.NEW0b, SFQ.NEW2/SFQ.NEW3) to encode the interview mode.

    • Revised the introduction for SCQ (SCQ_INTR) to include the updated language for Assurance of Confidentiality and Public reporting burden.

    • Replaced the questions on date of birth (DOB; SCQ.290, SCQ.291) with questions on age (SCQ.New1, SCQ.300). Updated sampling domains and weighting scheme for the 2021-22 cycle only require certain age categories to be identified, therefore, DOB information will no longer be collected for all household (HH) members in the screener to decrease respondent burden and to avoid collecting unnecessary personally identifiable information. DOB will be collected for sampled participants in the HH Sample Participant Questionnaire (HPQ).

    • Dropped the question on HH income level (SCQ.340) since no oversampling of low-income HHs will be performed in 2021-22 cycle.

    • Dropped branding questions (SCQ.500-SCQ.540) to decrease the respondent burden.

    • Updated the questions collecting phone number(s) from the respondent with modernized language. New question was included to ask permission for sending text messages related to study participation. Question on to whom the number was listed under is dropped.

    • Dropped questions on missing dwelling units (SCQ.560, SCQ.570, SFQ.260, SFQ.270). Previous data indicated only about 2-3 missing units identified in each survey location.
