Adherence to the oral contraceptive pill: the roles of health literacy and knowledge

Knowledge of non-contraceptive benefits of and willingness to consider taking oral contraceptive pills among a low-risk female population: a cross-sectional study

BACKGROUND

In addition to its widely-appreciated contraceptive applications, the oral contraceptive pill (OCP) conveys both oncological and non-oncological benefits. Oncological benefits include a decreased risk of endometrial, ovarian, and colorectal cancer. Non-oncological benefits include reducing androgenic effects and alleviating menstruation-related problems. This study aimed to ascertain knowledge levels of non-contraceptive benefits and risks of OCP use among participants without contraindications to OCPs. This study also assessed factors associated with participants being more likely to consider taking OCPs.

METHODS

263 women aged 21 to 40 years old with no contraindications for OCP usage participated in this study. An anonymous questionnaire collected sociodemographic information and assessed participants' knowledge of the non-contraceptive benefits and risks associated with OCP use. Multivariate linear regression was used to assess factors associated with knowledge levels. Multivariate logistic regression was used to investigate factors associated with being more likely to consider taking OCPs among women who did not presently take them.

RESULTS

Multivariate logistic regression revealed that participants who were more knowledgeable overall about the non-contraceptive benefits of OCPs were more likely to consider taking OCPs (coefficient = 0.184, p-value = 0.00). Knowledge of both oncological and non-oncological benefits of OCP use was relatively poor, especially among older women. Current OCP users were found to be more knowledgeable about their benefits.

CONCLUSIONS

As women with greater knowledge of non-contraceptive benefits of OCPs are more likely to consider taking them, knowledge gaps regarding OCPs should be filled, so that more women may reap the non-contraceptive benefits of OCPs.

Relationship between reproductive health literacy and components of healthy fertility in women of the reproductive age

BACKGROUND AND AIM

One of the key factors affecting women's behavior with fertility issues is their health literacy, but this topic has been less addressed in the existing studies. We aimed to determine the relationship between reproductive health literacy and components of healthy fertility in women of reproductive age.

MATERIALS AND METHODS

This cross-sectional study was conducted from March 2019 to September 2014 on 230 married women who were referred to comprehensive health centers in Lordegan city. Data were collected using a reproductive health literacy questionnaire, demographic and fertility information checklist, and components of healthy fertility. Data analysis was done using SPSS software, version 20. Pearson, Spearman, and independent t-tests were used as appropriate.

RESULTS

The mean ± SD reproductive health literacy score in the participants was 43.80 ± 18.99 depicting an average literacy level in more than half of the women. Also, the reproductive health literacy score had a statistically significant relationship with the use of low-failure contraceptive methods (P < 0.001) and planned pregnancy (P = 0.03). However, this relationship was not significant regarding pre-pregnancy care (P = 0.88) and observing the interval between pregnancies (P = 0.57).

CONCLUSION

We found a relationship between the level of reproductive health literacy and the use of family planning methods with low failure and planned pregnancy. Hence, it seems that interventions to improve reproductive health literacy are effective in reducing the occurrence of high-risk pregnancies and unwanted and unplanned pregnancies. Therefore, it is suggested that the health system consider and provide education related to reproductive health literacy as a part of healthy reproductive services.

A review of the pharmacology, clinical outcomes, and real-world effectiveness, safety, and non-contraceptive effects of NOMAC/E2

Selecting an appropriate oral contraceptive can be challenging for healthcare professionals due to the abundance of marketed contraceptive options with different clinical and real-world effectiveness and safety profiles. Nomegestrol acetate + 17β-estradiol (NOMAC/E2) is a combined oral contraceptive (COC) that inhibits ovulation by suppressing ovarian function by a 17-hydroxy-progesterone derivative and an estrogen identical to that endogenously produced by the ovaries. This narrative review examines clinical and real-world studies of NOMAC/E2 based on a background literature search using PubMed and Google Scholar. The review outlines the pharmacology of NOMAC/E2, including its progestational activity, pharmacokinetics, and effects on carbohydrate metabolism, lipid metabolism, and coagulation parameters, and summarizes key clinical efficacy and safety data that led to the approval of NOMAC/E2 in Europe, Brazil, and Australia. To help elucidate how NOMAC/E2 clinical trial data translate into a real-world setting, this review describes the effectiveness and safety of NOMAC/E2 in prospective studies that include over 90,000 users (half of whom received NOMAC/E2), outlining its effects on risk of thrombosis, menstrual bleeding patterns, weight, mood, acne, bone health, and patient quality of life. Non-contraceptive benefits of NOMAC/E2 for women with endometriosis, dysmenorrhea, or pre-menstrual dysphoric disorder are also discussed. These data demonstrate that NOMAC/E2 has a long half-life and rapid absorption, is effective at preventing unwanted pregnancies, and exhibits a favorable safety profile in both clinical trials and real-world settings. Importantly, NOMAC/E2 is not associated with increased risk of venous thromboembolism, a major safety concern of healthcare professionals for women receiving hormonal contraceptives. This review highlights NOMAC/E2 as a differentiated option among COCs and could help inform oral contraceptive choice to ultimately improve patient management and outcomes in real-world settings.

Can an online educational video broaden young women's contraceptive choice? Outcomes of the PREFER pre-post intervention study

INTRODUCTION

Contraceptive knowledge mediates access and use. We aimed to assess whether an online educational video describing all methods and their benefits, side effects and mode of action increased young women's contraceptive knowledge and their long-acting reversible contraception (LARC) preference and uptake.

METHOD

We used Facebook advertising to recruit young women aged 16-25 years. Participants completed the pre-video survey (S1), watched the 11-min video, then completed surveys immediately after (S2) and 6 months later (S3). Outcomes were analysed using McNemar tests and multivariate logistic regression (generalised estimating equations).

RESULTS

A total of 322 participants watched the video, completed S1 and S2, and 88% of those completed S3. At S1 only 6% rated their knowledge about every method as high. Knowledge improved at S2 for all methods (OR 10.0, 95% CI 5.9 to 17.1) and LARC (OR 4.2, 95% CI 3.1 to 5.7). LARC preference increased at S2 (OR 1.7, 95% CI 1.4 to 2.1) and S3 (OR 1.4, 95% CI 1.2 to 1.7), as did LARC uptake at S3 (OR 1.3, 95% CI 1.11 to 1.5). LARC uptake was driven by a 4.3% (n=12) absolute increase in intrauterine device (IUD) use, but there was no change in contraceptive implant use (p=0.8). The use of non-prescription methods such as condoms and withdrawal did not change (OR 0.92, 95% CI 0.76 to 1.11).

CONCLUSIONS

Many young women in Australia do not feel well informed about their contraceptive options. The contraceptive education video, delivered via social media, increased their self-reported contraceptive knowledge and IUD preference immediately after viewing, and their IUD uptake 6 months later. Focus should be given to how young women navigate contraceptive access after internet-based education, and strategies to increase access to preferred methods.

Adherence among a cohort taking progestin-only pills prescribed by a healthcare provider: Results of the BENCHMARK study

OBJECTIVES

To measure adherence over 6 months of progestin-only pill (POP) use.

STUDY DESIGN

Prospective observational cohort study measuring adherence to daily dosing and timing of dose in patients prescribed a POP, with up to six months of follow-up, conducted from January to October 2020. A pharmacy benefit manager identified potential participants with a newly prescribed POP and extended an invitation to participate. We enrolled qualified respondents by telephone, trained them to use an electronic diary to report daily whether they had taken their POP and at what time. We followed participants for up to six months. We calculated adherence to daily pill taking as the proportion of evaluable days in which a participant took a POP, and the proportion of participants reporting ≥85% adherence. We calculated adherence to same time each day as the proportion of doses taken no later than three hours after the previous dose time of day.

RESULTS

The user population comprised 199 participants, 154 (77.4%) of whom completed six months of follow-up. The majority (n=170, 85.4%) were taking norethindrone. Norethindrone users reported POP intake on 22,327 (96.4%) of 23,156 evaluable days, with 155 (91.2%) participants reporting ≥85% adherence; less than half (n=73, 42.9%) reported 100% adherence. Participants reported adherence to same time each day on 21,698 of 22,157 (97.9%) evaluable days.

CONCLUSIONS

Among participants taking a prescribed POP, participants demonstrated high adherence for daily pill taking and the same time of day, though the majority were not 100% adherent.

IMPLICATIONS

This study reports data specific to adherence among those taking a progestin-only pill (POP) in the prescription setting. Clinicians who counsel patients about POP use should be aware that majority of patients were not 100% adherent, although most report ≥ 85% adherence.

Adherence to Oral Contraception in Young Women: Beliefs, Locus of Control, and Psychological Reactance

Background: There is a high dropout rate of oral contraceptive pills (OCP), mainly due to a lack of adherence to treatment. The aim of this study was to identify the psychological processes and attitudes toward medication involved in adherence to OCP, depending on the prescription, to avoid unintended pregnancies (AUP) or gynecological problems (GP). Methods: This cross-sectional study was conducted by asking 689 young women in the fertile period, mean age 23.41 (SD = 5.90), to complete questionnaires related to attitudes, beliefs, psychological reactance, locus of control, and adherence to contraceptive medication. Descriptive analyses and a binary logistic regression were performed. Results: The results confirmed that different beliefs and psychological processes were involved in adherence to oral contraception, based on women’s reasons for taking contraceptive medication. More psychological processes were involved in non-adherence in the AUP group than in the GP group. Psychological reactance contributed most to explaining non-adherence in women who used the OCP to prevent unintended pregnancies. Conversely, women with gynecological problems reported difficulties in adherence, mainly due to their beliefs about contraceptive pills. Conclusions: These findings indicate that attitudes toward medication and psychological processes can play an important role in adherence to OCP, including reasons for using the pill. Identifying the psychological factors and beliefs linked with contraception could guide health professionals to provide counseling to women, thus increasing their adherence to medication and maximizing their health and well-being.
