Exposure-bracketing is a concept that applies known pharmacokinetics and pharmacodynamics of a drug substance to inform its safe and efficacious use in humans. Several therapeutic areas have applied this concept by leveraging established drug concentration-response relationships for approved products to expedite development and shorten the timeline for the approval of an investigational product containing the same drug substance. Based on discussions at a workshop hosted by the Bill &amp; Melinda Gates Foundation in December 2020, it appears feasible to apply exposure-bracketing to develop novel contraceptive products using well-characterized drugs.</p></div>","PeriodicalId":10655,"journal":{"name":"Contraception: X","volume":"4 ","pages":"Article 100072"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590151622000016/pdfft?md5=15f629b087d4947747c8ef99c9336ca6&pid=1-s2.0-S2590151622000016-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45555984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We studied the feasibility of providing the LNG-IUD through a primary care service, and its acceptability amongst women living in a low-income, rural-tribal community in India.</p></div><div><h3>Study design</h3><p>We conducted an observational study of feasibility and acceptability at four health facilities (three rural, and one urban) in Rajasthan, India. Women seeking contraception were offered the LNG-IUD in addition to existing contraceptive methods. We followed all those who adopted LNG-IUD from August 2015 to September 2019 (<em>n</em>= 1266) till discontinuation or 12 months, whichever was earlier. The primary outcome was continuation rate and acceptability, and the secondary outcome was change in hemoglobin levels, which we measured before insertion and at 12-month follow-up, using Sahli's method.</p></div><div><h3>Results</h3><p>Most users lived in villages, were illiterate, belonged to marginalized groups, had 2 or more children, and wished to limit births when they adopted the method. The 12-month continuation rate was 87.6%. Amongst all users, 7.4% of women sought removal for side effects and 2% for change in reproductive intention, while another 2% reported spontaneous expulsion. Most continuing users reported hypomenorrhea (54%) or amenorrhea (42%) by 12 months of use. User satisfaction was high at 91.6%, with 92% of women rating their experience as equaling or exceeding expectations. Moderate and severe anemia reduced, and mean hemoglobin levels increased by 0.7 g/dL (<em>p</em> &lt; 0.01).</p></div><div><h3>Conclusion</h3><p>Primary care clinics can feasibly deliver LNG-IUD, with high acceptability amongst women living in low resource settings. Given the paucity of long-acting reversible contraceptive options and high prevalence of anemia among women in India and similar countries, the method should be piloted through the public health system.</p></div><div><h3>Implications</h3><p>Long duration of contraceptive action, ability to reduce menstrual bleeding and reduce anemia, reversibility, and easy removal, combine to make LNG-IUD acceptable to women, especially in regions with high prevalence of anemia. This study demonstrates the feasibility and acceptability of introducing LNG-IUD in a low resource, primary care setting.</p></div>","PeriodicalId":10655,"journal":{"name":"Contraception: X","volume":"4 ","pages":"Article 100079"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/24/48/main.PMC9287359.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40608952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analytical sample (<em>n</em> = 2,469) included partnered women using contraception in the past year. We used multinomial logistic regression to examine associations between past-year pregnancy coercion (none, less severe, more severe) and partner knowledge/couple discussion of contraceptive use (overt use with couple discussion before method initiation (reference group), overt use with discussion after method initiation, and covert use of contraception).</p></div><div><h3>Results</h3><p>Most women reported their partner knew they were using contraception and had discussed use prior to method initiation (1,837/2,469, 75%); 16% used overtly and discussed use after method initiation, and 7% used contraception covertly. The proportion of covert users increased with pregnancy coercion severity (4%<sub>none</sub>, 14%<sub>less severe</sub>, 31%<sub>more severe</sub>), as did the proportion of overt users who delayed couple contraceptive discussions, (14%<sub>none</sub>, 23%<sub>less severe</sub>, 26% <sub>more severe</sub>); however, overt use with couple discussion before method initiation decreased with pregnancy coercion severity (79%<sub>none</sub>, 60%<sub>less severe</sub>, 40%<sub>more severe</sub>). The risk of covert use among women experiencing less severe pregnancy coercion was four times greater than women who experienced no pregnancy coercion (adjusted relative risk ratio, (aRRR) = 3.95, 95% confidence interval (CI) 2.20–7.09) and ten times greater for women who experienced the most severe pregnancy coercion (aRRR = 10.42, 95% CI 6.14–17.71). The risk of overt use with delayed couple discussion also increased two-fold among women who experienced pregnancy coercion compared to those who did not (less severe aRRR = 2.05, 95% CI 1.39–2.99; more severe aRRR = 2.89, 95% CI 1.76–4.73).</p></div><div><h3>Conclusion</h3><p>When experiencing pregnancy coercion, women may avoid or delay contraceptive conversations with their partners. Increased pregnancy coercion severity has the greatest association with covert use and couple contraceptive discussions.</p></div><div><h3>Implications</h3><p>The presence and timing of couple discussions about contraception are critical for ensuring safety for women experiencing pregnancy coercion. Screening for pregnancy coercion must be included within contraceptive counseling so that women can choose methods that maximize their reproductive autonomy.</p></div>","PeriodicalId":10655,"journal":{"name":"Contraception: X","volume":"4 ","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9525805/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33486377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
