Fertil Steril 2021; 116:208-217. [PMID: 33752880 DOI: 10.1016/j.fertnstert.2021.02.007] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 01/14/2021] [Accepted: 02/05/2021] [Indexed: 12/11/2022]
Abstract
OBJECTIVE To assess whether the duration, recency, or type of hormonal contraceptive used is associated with antimüllerian hormone (AMH) levels, given that the existing literature regarding the association between hormonal contraceptive use and AMH levels is inconsistent. DESIGN Cross-sectional study. SETTING Baseline data from the Study of the Environment, Lifestyle and Fibroids Study, a 5-year longitudinal study of African American women. PATIENT(S) The patients were 1,643 African American women aged 23-35 years at the time of blood drawing (2010-2012). INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Serum AMH level was measured by an ultrasensitive enzyme-linked immunosorbent assay. Linear regression models were used to estimate percent differences in mean AMH levels and 95% confidence intervals (CIs) according to use of hormonal contraceptives, with adjustment for potential confounders. RESULT(S) In multivariable-adjusted analyses, current users of hormonal contraceptives had 25.2% lower mean AMH levels than non-users of hormonal contraceptives (95% CI: -35.3%, -13.6%). There was little difference in AMH levels between former users and non-users of hormonal contraceptives (-4.4%; 95% CI: -16.3%, 9.0%). AMH levels were not appreciably associated with cumulative duration of use among former users or time since last use among non-current users. Current users of combined oral contraceptives (-24.0%; 95% CI: -36.6%, -8.9%), vaginal ring (-64.8%; 95% CI: -75.4%, -49.6%), and depot medroxyprogesterone acetate (-26.7%; 95% CI: -41.0%, -8.9%) had lower mean AMH levels than non-users. CONCLUSION(S) The present data suggest that AMH levels are significantly lower among current users of most forms of hormonal contraceptives, but that the suppressive effect of hormonal contraceptives on AMH levels is reversible.

Abstract
PURPOSE To identify and describe publications addressing the agreement between self-reported medication and other data sources among adults and, in a subgroup of studies dealing with cancer patients, seek to identify parameters which are associated with agreement. METHODS A systematic review including a systematic search within five biomedical databases up to February 28, 2019 was conducted as per the PRISMA Statement. Studies and agreement results were described. For a subgroup of studies dealing with cancer, we searched for associations between agreement and patients' characteristics, study design, comparison data source, and self-report modality. RESULTS The literature search retrieved 3392 publications. Included articles (n = 120) show heterogeneous agreement. Eighteen publications focused on cancer populations, with relatively good agreement identified in those which analyzed hormone therapy, estrogen, and chemotherapy (n = 11). Agreement was especially good for chemotherapy (proportion correct ≥93.6%, kappa ≥0.88). No distinct associations between agreement and age, education or marital status were identified in the results. There was little evaluation of associations between agreement and study design, self-report modality and comparison data source, thus not allowing for any conclusions to be drawn. CONCLUSION An overview of the evidence available from validation studies with a description of several characteristics is provided. Studies with experimental design which evaluate factors that might affect agreement between self-report and other data sources are lacking.

[PMID: 28966052 PMCID: PMC5858917 DOI: 10.1016/j.contraception.2017.09.013] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2017] [Revised: 09/18/2017] [Accepted: 09/23/2017] [Indexed: 12/21/2022]
Abstract
Objective Researchers traditionally rely on participant self-report for contraceptive use. We hypothesized that self-reported contraceptive use by clinical research participants may disagree with objectively measured hormonal status. Study design We enrolled women in Harare, Zimbabwe, aged 18–34, who by self-report had not used hormonal or intrauterine contraception for >30 days, or depot medroxyprogesterone acetate for >10 months, into a study designed to assess biologic changes with contraceptive initiation and use. Blood samples obtained at enrollment and each follow-up visit (N=1630 from 447 participants) were evaluated by mass spectrometry for exogenous hormones. We individually interviewed a subset of participants (n=20) with discrepant self-reported and measured serum hormones to better understand nondisclosure of contraceptive use. Results Discrepant with self-reported nonuse of hormonal contraception, synthetic progestogens were detectable in 120/447 (27%, 95% confidence interval 23%–31%) enrolled women. Measured exogenous hormones consistent with use of contraceptive pills (n=102), injectables (n=20) and implants (n=3) were detected at enrollment, with 7 women likely using >1 contraceptive. In-depth interviews revealed that participants understood the requirement to be hormone free at enrollment (100%). Most (85%) cited partner noncooperation with condoms/withdrawal and/or pregnancy concerns as major reasons for nondisclosed contraceptive use. All interviewed women (100%) cited access to health care as a primary motivation for study participation. Of participants who accurately reported nonuse of hormonal contraception at enrollment, 41/327 (12.5%) had objective evidence of nonstudy progestin use at follow-up that disagreed with self-reported nonuse. Conclusions Women joining contraceptive research studies may misrepresent their use of nonstudy contraceptive hormones at baseline and follow-up. Objective measures of hormone use are needed to ensure that study population exposures are accurately categorized. Implications statement Among Zimbabwean women participating in a contraceptive research study, 27% had objective evidence of use of nonstudy contraceptives at enrollment that disagreed with self-report. Studies that rely on self-report to identify contraceptive hormone exposure could suffer from significant misclassification.

Abstract
OBJECTIVE The effect of oral contraceptive (OC) use on risk of fracture remains unclear, and use during later reproductive life may be increasing. To determine the association between OC use during later reproductive life and risk of fracture across the menopausal transition, we conducted a population-based case-control study in a Pacific Northwest HMO, Group Health Cooperative. METHODS For the January 2008 to March 2013 interval, 1,204 case women aged 45 to 59 years with incident fractures, and 2,275 control women were enrolled. Potential cases with fracture codes in automated data were adjudicated by electronic health record review. Potential control women without fracture codes were selected concurrently, sampling based on age. Participants received a structured study interview. Using logistic regression, associations between OC use and fracture risk were calculated as odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS Participation was 69% for cases and 64% for controls. The study sample was 82% white; mean age was 54 years. The most common fracture site for cases was the wrist/forearm (32%). Adjusted fracture risk did not differ between cases versus controls for OC use in the 10 years before menopause (OR 0.90, 95% CI 0.74, 1.11); for OC use after age 38 (OR 0.94, 95% CI 0.78, 1.14); for duration of use, or for other OC exposures. CONCLUSIONS The current study does not show an association between fractures near the menopausal transition and OC use in the decade before menopause or after age 38. For women considering OC use at these times, fracture risk does not seem to be either reduced or-reassuringly-increased.
