Hypertension among Oral Contraceptive Users in El Paso, Texas

On the U.S.-Mexico border, residents frequently cross into Mexico to obtain medications or medical care. We previously reported relatively high prevalence of hypertension among Latina oral contraceptive users in El Paso, particularly those obtaining pills over the counter (OTC) in Mexico. Here, we examine factors associated with having hypertension among 411 OTC users and 399 clinic users. We also assess hypertension awareness and interest in using blood pressure kiosks. Women age 35 to 44 and who had BMI ≥ 30 kg/m2 had higher odds of having hypertension. 59% of hypertensive women had unrecognized hypertension, and 77% of all participants would use a blood pressure kiosk; there were no significant differences between clinic and OTC users. Alternative approaches to increase access to health screenings are needed in this setting, where OTC pill use among women with unrecognized hypertension confers unique health risksPopulation Research Cente

Contraindications of progestin-only oral contraceptive pills among reproductive-aged women

BACKGROUND: Progestin-only oral contraceptive pills (POPs) have fewer contraindications to use compared to combined pills. However, the overall prevalence of contraindications to POPs among reproductive aged women has not been assessed. STUDY DESIGN: We collected information on contraindications to POPs in two studies : 1) the Self-Screening Study, a sample of 1,267 reproductive aged women in the general population in El Paso, Texas and 2) the Prospective Study of Oral Contraceptive (OC) Users, a sample of current OC users who obtained their pills in El Paso clinics (n=532) or over the counter (OTC) in Mexican pharmacies (n=514). In the Self-Screening Study, we also compared women’s self-assessment of contraindications using a checklist to a clinicain’s evaluation. RESULTS: Only 1.6% of women in the Self-Screening Study were identified as having at least one contraindication to POPs. The sensitivity of the checklist for identifying women with at least one contraindication was 75.0% (95% CI: 50.6-90.4%), and the specificity was 99.4% (95% CI: 98.8-99.7%). In total, 0.6% of women in the Prospective Study of OC Users reported having any contraindication to POPs. There were no significant differences between clinic and OTC users. CONCLUSION: The prevalence of contraindications to POPs was very low in these samples. POPs may be the best choice for the first OTC oral contraceptive in the US.The Eunice Kennedy Shriver National Institute of Child Health and Human Development (R01HD047816).http://www.journals.elsevier.com/contraception

Knowledge & Beliefs about Reproductive Anatomy and Physiology among Mexican-Origin Women in the U.S.: Implications for Effective Oral Contraceptive Use

Inherent in many reproductive health and family planning programmes is the problematic assumption that the body, its processes, and modifications to it are universally experienced in the same way. This paper addresses contraceptive knowledge and beliefs among Mexican-origin women, based upon data gathered by the qualitative component of the Border Contraceptive Access Study. Open-ended interviews explored the perceived mechanism of action of the pill, side effects, non-contraceptive benefits, and general knowledge of contraception. Findings revealed complex connections between traditional and scientific information. Use of medical terms (“hormone”) illustrated attempts to integrate new information with existing knowledge and belief systems. Conclusions address concerns that existing information and services may not be sufficient if population-specific knowledge and beliefs are not assessed and addressed. Findings can contribute to the development of effective education, screening, and reproductive health services

Accuracy of self-screening for contraindications to combined oral contraceptive use

Objective: To estimate how well a convenience sample of women from the general population could self-screen for contraindications to combined oral contraceptives using a medical checklist. Methods: Women 18–49 years old (N = 1,271) were recruited at two shopping malls and a flea market in El Paso, Texas, and asked first whether they thought birth control pills were medically safe for them. They then used a checklist to determine the presence of level 3 or 4 contraindications to combined oral contraceptives according to the World Health Organization Medical Eligibility Criteria. The women then were interviewed by a blinded nurse practitioner, who also measured blood pressure. Results: The sensitivity of the unaided self-screen to detect true contraindications was 56.2% (95% confidence interval [CI] 51.7–60.6%), and specificity was 57.6% (95% CI 54.0–61.1%). The sensitivity of the checklist to detect true contraindications was 83.2% (95% CI 79.5–86.3%), and specificity was 88.8% (95% CI 86.3–90.9%). Using the checklist, 6.6% (95% CI 5.2–8.0%) of women incorrectly thought they were eligible for use when, in fact, they were contraindicated, largely because of unrecognized hypertension. Seven percent (95% CI 5.4–8.2%) of women incorrectly thought they were contraindicated when they truly were not, primarily because of misclassification of migraine headaches. In regression analysis, younger women, more educated women, and Spanish speakers were significantly more likely to correctly self-screen (P \u3c .05). Conclusion: Self-screening for contraindications to oral contraceptives using a medical checklist is relatively accurate. Unaided screening is inaccurate and reflects common misperceptions about the safety of oral contraceptives. Over-the-counter provision of this method likely would be safe, especially for younger women and if independent blood pressure screening were encouraged
