Component Description

This section contains questions for females only, on reproductive health, including menstrual history, pregnancy history, lactation, oral contraceptive and hormone replacement therapy use and other related conditions.

Eligible Sample

Mobile examination female participants 12 years and older were eligible.

Interview Setting and Mode of Administration

These questions were administered as part of the MEC interview questionnaire, using the Computer-Assisted Personal Interviewing-CAPI (interviewer administered) system in Spanish or English. Both proxy interviewers and interpreters were permitted for these questions.

Quality Assurance & Quality Control

The CAPI system is programmed with built-in consistency checks to reduce data entry errors. CAPI also uses online help screens to assist interviewers in defining key terms used in the questionnaire.

Approximately 5% of the interviews were recorded and reviewed for quality control purposes.

Data Processing and Editing

The reproductive health questionnaire is a complex, detailed set of questions that are administered according to age and skip patterns based on responses to various reproductive health conditions. While the data were reviewed and edited for completeness and illogical values, some inconsistencies in the response to these self-reported questions remain. Data analysts are strongly encouraged to carefully review all variables of interest prior to data analysis.

Analytic Notes

This data file contains all variables for females 12 years and older, whereas the publicly released data set (RHQ_F) has limited information for females 12-19 years of age due to possible disclosure risks.

Due to sample design changes starting in 2007, pregnant women and individuals 12-19 were no longer oversampled. Additionally, for each of the race/ethnicity domains, the former 12-15 and 16-19 year age domains were combined and the 40-59 year age minority domains were split into two 10-year age sampling domains: 40-49 and 50-59. These changes result in an increase in the actual number of participants 40-59 years and a decrease in 12-19 year olds, as compared to previous cycles. Therefore, unweighted frequencies of certain reproductive conditions may differ slightly in this survey cycle compared to survey cycles prior to 2007. For further discussion, please see the NHANES 2009 - 2010 Public Data General Release File Documentation, available on the NHANES website at: https://wwwn.cdc.gov/nchs/nhanes/continuousnhanes/default.aspx?BeginYear=2009

Notes for specific variables:
RHD143: Current pregnancy by self-report is collected primarily to determine appropriate question skip patterns according to various reproductive conditions in this section. However, analysts are strongly advised to use the all inclusive pregnancy variable RIDEXPREG, found in the Demographic data file, for all analyses where the determination of pregnancy status is necessary. RIDEXPREG includes both self-reported and the results of the urine pregnancy test.

MEC exam sample weights should be used for the analyses.

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.
