The reproductive health section (variable name prefix RHQ) contains questions for females only. Questions on reproductive health include menstrual history, pregnancy history, hormone replacement therapy use, and other related reproductive conditions. New questions on fertility history were added for the 2013-2014 cycle, and several questions were excluded from earlier versions, including details on lactation history, contraceptive use, and hormone therapy use.
Female participants aged 12 years and older were eligible.
These questions were asked at the mobile examination center, by trained interviewers, using the Computer-Assisted Personal Interview (CAPI) system as part of the Mobile Examination Center (MEC) interview. Both proxy interviewers and interpreters were permitted for these questions.
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.
Edits were made to ensure the completeness, consistency and analytic usefulness of the data.
This is the complete data file containing all variables for females 12 years and older. Select variables related to pregnancy and hysterectomy were excluded from the public-use data file and documentation for those aged 12-19 years and over 44 years due to disclosure risks.
MEC exam sample weights should be used for the analyses. Due to sample design changes starting in 2007, pregnant women and persons 12-19 were no longer oversampled. Additionally, for each of the race/ethnicity domains, the former age domains 12-15 and 16-19 were combined and the age minority domain 40-59 was split into two 10-year age sampling domains: 40-49 and 50-59. These changes resulted in an increase in the actual number of participants aged 40-59 years and a decrease in participants aged 12-19 years, 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 https://wwwn.cdc.gov/nchs/nhanes/continuousnhanes/default.aspx?BeginYear=2013, available on the NHANES website.
In the 2013-2014 questionnaire, questions were added on infertility history and about pelvic inflammatory disease. Approximately 14 questions were dropped to streamline this part of the MEC interview and reduce participant burden. Those excluded were related primarily to lactation history, contraceptive use, and hormone replacement use. The order of questions was modified slightly from the 2011-2012 version, and a few questions were slightly reworded. The response categories for the question on “reason not had a period in the past 12 months” (now named “RHD043”) now includes separate categories for hysterectomy and menopause, and excludes the former category “medical conditions/treatments.” Analysts should carefully review both the questionnaire and the documentation when combining variables across cycles.
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.
