Component Description

Human papillomavirus (HPV) infection is one of the most common sexually transmitted infections in the United States. Cervical infection with certain types of HPV is a major risk factor for cervical cancer in women. No national surveillance system exists to measure the full burden of HPV infection, and no reliable national population estimate of HPV exists. NHANES offers a unique opportunity to assess the prevalence of HPV infection in the general population.

Reducing the prevalence of HPV infection is a Developmental Healthy People 2010 objective: “Reducing the number of new HPV cases can help minimize the overall number of cases of high risk subtypes associated with cervical cancer in females ...” An HPV vaccine has been licensed, and knowledge of the national prevalence of HPV infection is critical for planning vaccination strategies and monitoring the impact of vaccination in the United States.

Eligible Sample

All participants aged 14 to 59 years.

Description of Laboratory Methodology

Multiplex Luminex Assay of Antibodies to Neutralizing Epitopes on HPV 6, 11, 16 and 18 L1-Virus-Like Particles (VLPs)

This method uses the Luminex platform to simultaneously assay antibodies to HPV 6, 11, 16 and 18. Type-specific antibodies of any Ig class are detected by displacement of fluorescently tagged neutralizing monoclonal antibody from VLP-coated microspheres.

Data Processing and Editing

Blood specimens were processed, stored and shipped to Atlanta, Ga. for analysis. Detailed specimen collection and processing instructions are discussed in the NHANES LPM. Read the LABDOC file for detailed data processing and editing protocols. The analytical methods are described in the Description of the Laboratory Methodology section. The Multiplex Luminex assay was conducted at Merck Research Laboratories using their protocol established for vaccine clinical trials.

Analytic Notes

The analysis of NHANES 2003–2004 laboratory data must be conducted with the key survey design and basic demographic variables. The NHANES 2003–2004 Household Questionnaire Data Files contain demographic data, health indicators, and other related information collected during household interviews. They also contain all survey design variables and sample weights for these age groups. The phlebotomy file includes auxiliary information such as the conditions precluding venipuncture. The household questionnaire and phlebotomy files may be linked to the laboratory data file using the unique survey participant identifier SEQN.

Serology Assay.

Competitive Luminex Assay for HPV 6, 11, 16, 18: Merck established the serostatus cut-off values for a positive result for each HPV type in the assay.
