The Website (https://wwwn.cdc.gov/Nchs/Nhanes/2015-2016/INQ_I.htm) gives the following Analytic notes: "The income questions were asked as part of household interview, the interview sample weights may be used in the analysis for data in this section. However, if the data is joined with other data from the Mobile Examination Center (MEC), the MEC exam weights should be used. Please refer to the NHANES Analytic Guidelines and the on-line NHANES Tutorial for further details on the use of sample weights and other analytic issues. Both of these are available on the NHANES website."
