Exp. Date XX/XX/20XX

Notice – CDC estimates the average public reporting burden for this collection of information as 3 hours per response, including the time for reviewing instructions, searching existing data/information sources, gathering and maintaining the data/information needed, and completing and reviewing the collection of information. An agency may not conduct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden to CDC/ATSDR Information Collection Review Office, 1600 Clifton Road, MS D-74, Atlanta, GA 30333; ATTN: PRA (0920-0950).


Assurance of ConfidentialityWe take your privacy very seriously.  All information that relates to or describes identifiable characteristics of individuals, a practice, or an establishment will be used only for statistical purposes.  NCHS staff, contractors, and agents will not disclose or release responses in identifiable form without the consent of the individual or establishment in accordance with section 308(d) of the Public Health Service Act (42 U.S.C. 242m(d)) and the Confidential Information Protection and Statistical Efficiency Act (CIPSEA Pub. L. No. 115-435, 132 Stat. 5529 § 302).  In accordance with CIPSEA, every NCHS employee, contractor, and agent has taken an oath and is subject to a jail term of up to five years, a fine of up to $250,000, or both if he or she willfully discloses ANY identifiable information about you. In addition to the above cited laws, NCHS complies with the Federal Cybersecurity Enhancement Act of 2015 (6 U.S.C. §§ 151 and 151 note) which protects Federal information systems from cybersecurity risks by screening their networks.


Up to 3,500 additional persons might participate in tests of procedures or special studies if budgeted. The average burden for these special study/pretest respondents is 3 hours. This may include cognitive testing of questions proposed for inclusion in NHANES. This would be done to make sure that wording of proposed questions are clear and understandable to potential respondents. Another example would be testing an examination procedure to see if it could be done in a small enough space and fast enough time frame, to make if feasible to do in the NHANES Mobile Examination Center (MEC). Special Studies could also include projects like the 24-hour urine calibration study. This proposed study was designed to evaluate the correlation of urinary sodium excretions between NHANES timed urine and 24-hour urine collections. The major objectives of the calibration study were as follows:

• To assess how well the sodium excretion estimated from an NHANES timed urine correlates with data from a 24-hour urine collection.

• To assess the correlation of 24-hour sodium excretion with different NHANES timed urines collected at varying times of day

• To develop calibration equations to estimate 24-hour urine sodium excretion using data from NHANES timed urine samples
