Abstract
The use of safe and effective contraception is essential for preventing unplanned pregnancy in women of all body sizes. When counseling women with obesity about contraception, it is important to consider the pharmacokinetic alterations of obesity on various modern contraceptive methods. However, evidence is reassuring that most contraceptive methods are safe and effective in women with obesity. Individual countries and the World Health Organization have published Medical Eligibility Criteria to guide contraceptive selection in women with medical issues including obesity. When choosing contraception, specific risks of the method relative to any underlying medical disorders must also be balanced against the risks of unintended pregnancy in this group.

Brufatto JPT, Dias TM, D'abreu NB, Rehder PM. Reproductive Planning and the Choice of Long-acting Reversible Contraceptive Primary to Health: A Cross-Sectional Study. REVISTA BRASILEIRA DE GINECOLOGIA E OBSTETRÍCIA 2023; 45:e456-e464. [PMID: 37683657 PMCID: PMC10491473 DOI: 10.1055/s-0043-1772188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 03/21/2023] [Indexed: 09/10/2023] Open
Abstract
OBJECTIVE Evaluate the different perspectives that involve the choice of long-acting reversible contraceptives (LARCs), the issues related to this process and the consequences of deciding one method in the women's in the primary health care (PHC) center in Sousas, a district in Campinas, SP (Brazil). METHODS This is an analytical cross-sectional study, it was performed at the PHC in Sousas. Data were collected through the analysis of medical records and interviews with women who live in Sousas and had the insertion of the copper intrauterine device (IUD) (D) from April 2021 to April 2022 or the etonogestrel implant (I) from May to December 2022. The study was approved by the Research Ethics Committee of the Medical Science School at the State University of Campinas (UNICAMP). RESULTS Reason for choosing this LARC: medical (D: 52%; I: 100%), easy adhesion (D: 71%; I: 67%), effectiveness (D: 55%; I: 100%). Indication by health professionals (D: 65%; I: 100%). And improvement of clinical characteristics: mood (D: 77%; I: 67%), body mass index (BMI; D: 52%; I: 33%), and libido (D: 84%; I: 67%). CONCLUSION It is suggested that women tend to decide between LARCs when guided by their doctor or PHC health professionals, and they select LARCs because of the ease of use and low failure rates. Therefore, this study highlights how LARCs can positively interfere in the aspects that pervade contraception, such as BMI, libido, and mood.

Abstract
Adolescents are at risk for unwanted pregnancy when they become sexually active, and contraception is an important part of mitigating this risk. Use of contraceptive methods, and long-acting reversible contraceptive methods such as implants and intrauterine devices in particular, has increased among adolescents. Although sexual activity has declined and contraceptive use has increased among adolescents in the United States in recent years, the unintended pregnancy rate remains high. All of the currently available contraceptive methods are safe and effective for adolescents to use; however, adolescents may have specific concerns about side effect profiles and unscheduled bleeding that should be addressed during contraceptive counseling. Healthcare providers should prioritize adolescents' needs and preferences when approaching contraceptive counseling, and also consider the unique access and confidentiality issues that adolescents face when accessing contraception.

Obesity and hormonal contraception: an overview and a clinician's practical guide. Eat Weight Disord 2020; 25:1129-1140.

Abstract
BACKGROUND The growing prevalence of obesity among the fertile female population poses a considerable problem to contraceptive providers. Obese women, who are more at risk for venous thromboembolism and cardiovascular events due to their condition, might be at an even higher risk of developing thromboembolic events when on medical contraception. Combined hormonal contraceptives might be less effective in obese women and may lead to unacceptable metabolic side effects for this population. In addition, the lack of safety data for weight loss drugs and the higher risk for complications during and after pregnancy require a close surveillance of the fertility status of obese patients. OBJECTIVE The aim of this narrative review is to summarize the available medical contraceptive options and to give the readers a practical guidance for a wise contraceptive choice with regards to obesity. METHODS A general literature review of peer-reviewed publications on the topic "obesity and contraception" was performed using the PubMed database. RESULTS Nowadays, there are many useful tools that help clinicians in choosing among the wide range of therapeutic possibilities, such as the World Health Organization (WHO) Medical Eligibility Criteria for contraceptive use. Furthermore, the great diversity of hormonal contraceptive formulations (combined hormonal formulations; progestin-only methods) and active substances (different estrogens and progestins) allow physicians to tailor therapies to patients' clinical peculiarities. CONCLUSION Long-acting reversible contraceptives [progestin-only implants, levonorgestrel-intra-uterine devices (IUDs) and copper IUDs] and progestin-only methods in general are excellent options for many categories of patients, including obese ones. LEVEL OF EVIDENCE V, narrative review.

Abstract
OBJECTIVE This guideline will review key aspects in the pregnancy care of women with obesity. Part I will focus on Preconception and Pregnancy Care. Part II will focus on Team Planning for Delivery and Postpartum Care. INTENDED USERS All health care providers (obstetricians, family doctors, midwives, nurses, anaesthesiologists) who provide pregnancy-related care to women with obesity. TARGET POPULATION Women with obesity who are pregnant or planning pregnancies. EVIDENCE Literature was retrieved through searches of Statistics Canada, Medline, and The Cochrane Library on the impact of obesity in pregnancy on antepartum and intrapartum care, maternal morbidity and mortality, obstetric anaesthesia, and perinatal morbidity and mortality. Results were restricted to systematic reviews, randomized controlled trials/controlled clinical trials, and observational studies. There were no date or language restrictions. Searches were updated on a regular basis and incorporated in the guideline to September 2018. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALIDATION METHODS The content and recommendations were drafted and agreed upon by the authors. Then the Maternal-Fetal Medicine Committees peer reviewed the content and submitted comments for consideration, and the Board of the Society of Obstetricians and Gynaecologists of Canada (SOGC) approved the final draft for publication. Areas of disagreement were discussed during meetings at which time consensus was reached. The level of evidence and quality of the recommendation made were described using the Evaluation of Evidence criteria of the Canadian Task Force on Preventive Health Care. BENEFITS, HARMS, AND COSTS Implementation of the recommendations in these guidelines may increase obstetrical provider recognition of the issues affecting pregnant individuals with obesity, including clinical prevention strategies, communication between the health care team, the patient and family as well as equipment and human resource planning. It is hoped that regional, provincial and federal agencies will assist in the education and support of coordinated care for pregnant individuals with obesity. GUIDELINE UPDATE SOGC guideline will be automatically reviewed 5 years after publication. However, authors can propose another review date if they feel that 5 years is too short/long based on their expert knowledge of the subject matter. SPONSORS This guideline was developed with resources funded by the SOGC. SUMMARY STATEMENTS RECOMMENDATIONS.

Abstract
Gestational diabetes mellitus (GDM) complicates approximately 7% of pregnancies in the United States. Along with risk factors related to pregnancy, women with a history of GDM also have an increased risk of developing type 2 diabetes mellitus later in life. These women require special consideration when discussing contraception and other reproductive health issues. GDM carries a category 1 rating in the US Medical Eligibility Criteria for all contraceptive methods, which supports safety of the various methods but does not account for effectiveness. Contraceptive options differ in composition and mechanisms of action, and concerns have been raised about possible effects of contraception on metabolism. Clinical evidence is limited to suggest that hormonal contraception has significantly adverse effects on body weight, lipid, or glucose metabolism. In addition, the majority of evidence does not suggest a relationship between development of type 2 diabetes mellitus and use of hormonal contraception. Data are limited, so it is challenging to make a broad, general recommendation regarding contraception for women with a history of GDM. A woman’s history of GDM should be considered during contraceptive counseling. Discussion should focus on potential medical comorbidities and the implications of GDM on future health, with special consideration of issues including bone health, obesity, cardiovascular disease, and thrombosis risk. Providers must emphasize the importance of reliable, highly effective contraception for women with GDM, to optimize the timing of future pregnancies. This approach to comprehensive counseling will guide optimal decision-making on contraceptive use, lifestyle changes, and planning of subsequent pregnancies.

Abstract
Although numerous studies have addressed the safety and effectiveness of hormonal contraceptive use in healthy women, data regarding women with underlying medical conditions or other special circumstances are limited. The U.S. Medical Eligibility Criteria (USMEC) for Contraceptive Use, 2016 (), which has been endorsed by the American College of Obstetricians and Gynecologists, is a published guideline based on the best available evidence and expert opinion to help health care providers better care for women with chronic medical problems who need contraception. The goal of this Practice Bulletin is to explain how to use the USMEC rating system in clinical practice and to specifically discuss the rationale behind the ratings for various medical conditions. Contraception for women with human immunodeficiency virus (HIV) (); the use of emergency contraception in women with medical coexisting medical conditions, including obesity, (); and the effect of depot medroxyprogesterone acetate (DMPA) on bone health () are addressed in other documents from the American College of Obstetricians and Gynecologists.

La partie 2 porte sur la planification en équipe de l'accouchement et les soins post-partum. UTILISATEURS CONCERNéS: Tous les fournisseurs de soins de santé (obstétriciens, médecins de famille, sages-femmes, infirmières, anesthésiologistes) qui prodiguent des soins relatifs à la grossesse auprès de femmes atteintes d'obésité. POPULATION CIBLE Femmes atteintes d'obésité qui sont enceintes ou prévoient le devenir. DONNéES PROBANTES: Des recherches ont été menées en consultant les ressources de Statistique Canada, de Medline et de Cochrane Library en vue d'en tirer la littérature relativement aux effets de l'obésité durant la grossesse sur les soins prénataux et intrapartum, la morbidité et la mortalité maternelles, l'anesthésie obstétricale ainsi que sur la morbidité et la mortalité périnatales. Seuls les résultats de revues systématiques, d'essais cliniques randomisés ou comparatifs et d'études observationnelles ont été retenus. Aucune restriction de date ou de langue n'a été employée. Les recherches ont été mises à jour régulièrement, et les résultats ont été incorporés à la directive clinique jusqu'en septembre 2018. Nous avons également tenu compte de la littérature grise (non publiée) obtenue sur les sites Web d'organismes d'évaluation des technologies de la santé et d'autres organismes pertinents, dans des collections de directives cliniques et des registres d'essais cliniques, et auprès d'associations nationales et internationales de médecins spécialistes. MéTHODES DE VALIDATION: Le contenu et les recommandations ont été rédigés et acceptés par les auteurs. Les membres du comité de médecine fœto-maternelle ont ensuite passé en revue le contenu et formulé des commentaires aux fins d'examen. Enfin, le conseil d'administration de la Société des obstétriciens et gynécologues du Canada (SOGC) a approuvé la publication de la version définitive de la directive. Les points de désaccord ont été abordés lors de réunions pour enfin arriver à un consensus. La qualité des données et des recommandations a été déterminée à l'aide des critères d'évaluation décrits par le Groupe d'étude canadien sur les soins de santé préventifs. AVANTAGES, PRéJUDICE ET COûTS: La mise en place des recommandations des présentes directives peut améliorer la reconnaissance des fournisseurs de soins obstétricaux relativement aux problèmes qui touchent les personnes enceintes atteintes d'obésité, notamment au moyen de stratégies de prévention clinique; de la communication entre l'équipe de soins de santé, la patiente et la famille; et de la planification de l'équipement et des ressources humaines. Il est à espérer que les organismes régionaux, provinciaux et fédéraux participeront à la formation et au soutien en matière de soins coordonnés pour les personnes enceintes atteintes d'obésité. MISE à JOUR DE LA DIRECTIVE CLINIQUE: Les directives de la SOGC sont automatiquement passées en revue 5 ans après leur publication. Les auteurs peuvent toutefois proposer une autre date de réévaluation s'ils croient qu'une période de 5 ans est trop courte ou trop longue en fonction de leurs connaissances du sujet à titre d'experts en la matière.

Abstract
Purpose: This study aimed to explore the prescription of different contraceptive methods to Swedish women with obesity and to compare the pattern of prescription and adherence to treatment between this group and normal-weight women. Materials and methods: This study included 371 women with obesity and 744 matched normal-weight women, aged 18-40. Medical records were scrutinised for the period 1 January 2010 to 31 December 2014. The retrieved variables included: background characteristics, prescribed contraceptive methods, adverse effects, duration of treatment, reason for discontinuation and bleeding pattern. Result: Progestin-only pills were mainly prescribed to women with obesity (44% vs. 20%, p = 0.001) whereas combined hormonal contraception was mainly prescribed to normal-weight women (60% vs. 21%, p < 0.0001). Thirty-three percent vs. 25% (p = 0.003) discontinued their contraceptive method within 1 year. The most commonly declared reason for discontinuation was bleeding disturbance (14.7% vs. 9.6%, p = 0.008). Conclusion: The most commonly prescribed contraceptive method in women with obesity was progestin-only pills, but surprisingly many women with obesity were prescribed combined hormonal contraception despite current Swedish and European guidelines. Incident users with obesity were significantly more likely to discontinue their contraceptive method within the first year of the study period, compared with incident normal-weight users.

Abstract
OBJECTIVE The objective was to evaluate the pharmacokinetics (PKs) of levonorgestrel (LNG)-containing combined oral contraceptives (COCs) in obese women. STUDY DESIGN We pooled and reanalyzed data from 89 women with different body mass index (BMI) categories from four clinical studies. The LNG and ethinyl estradiol (EE) PKs were analyzed utilizing a zero-order absorption (K0), two-compartment PK model to evaluate key PK parameters in relation to a range of weights, BMI and body surface area (BSA). RESULTS Increasing of body habitus metrics is correlated with decreasing Cmax (p<.0001) and AUCτ (p<.05) for both LNG and EE, but no correlation was found for Cmin (p≥.17). Increasing weight and BMI were associated with a modest increase (p≤.056) of clearance (CL) and appreciable increases of central volume (V1, p<.05), distribution clearance (CLd, p≤.001) and peripheral volume (V2, p<.0001) for LNG. For EE, increases in CL (p≤.009) were found with greater weight, BMI and BSA. Values of V1, CLd and V2 also increased (p<.0001) in obese subjects. The half-life and steady-state volume were greater among obese women (p<.0001) for both LNG and EE. LNG and EE PK parameters correlated well (p≤.006 for all), indicating that individual subject physiology affected both drugs similarly. CONCLUSIONS The primary effects of obesity on LNG and EE were a modest increase in CL and a marked increase in distribution parameters. We observed no obesity-related differences in trough LNG and EE concentrations. IMPLICATIONS This population PK analysis demonstrated reduced systemic exposure to LNG/EE oral contraceptives in obese subjects (Cmax and AUCτ); these particular differences are unlikely to lower contraceptive effectiveness among obese women who are correctly using LNG-containing contraceptives.

Abstract
Long acting reversible contraception (LARC) is the recommend form of birth control for adolescents by both the American Academy of Pediatrics and the American Congress of Obstetrics and Gynecology, but the majority of adolescents continue to use short acting reversible contraception (SARC) such as the oral contraceptive pill, vaginal ring, and transdermal patch. For this reason, it is important for medical providers to be familiar with how to prescribe and manage SARC in adolescents, paying particular attention to which patients are eligible to use them, which benefits the methods have outside of contraception, what side effects to be aware of, and special considerations for adolescents. Many adolescents will choose not to use any form of hormonal contraception-thus having a knowledge about and comfort with use of emergency contraception is of equal importance.

Abstract
OBJECTIVE To provide consensus recommendations for health-care providers on the use of oral contraceptive pills (OCPs) in polycystic ovarian syndrome (PCOS) women in India. PARTICIPANTS Extensive deliberations, discussions, and brainstorming were done with different fraternities (specialists) being involved. These included endocrinologists, gynecologists, reproductive endocrinologists, dermatologists, public health experts, researchers, and a project manager with a team to develop the guideline. EVIDENCE Published literature was retrieved through searches of Medline and The Cochrane Database from January 2003 to December 2017 using appropriate-controlled vocabulary (e.g., oral contraceptive pills, polycystic ovarian syndrome, long term outcomes, infertility). Clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies' publications and data were also reviewed to suggest the recommendations. PROCESS The working group for guideline committee included members from the PCOS Society (India), Indian Society for Assisted Reproduction, The Mumbai Obstetric and Gynecological Society, The Endocrine Society of India, Indian Association of Dermatologists, Venereologists and Leprologists, Cosmetic Dermatology Society (India), Academicians from Medical Colleges, National Institute for Research in Reproductive Health, and a Research Associate. The core team included five reproductive endocrinologists, five gynecologists, five dermatologists, three endocrinologists, two public health experts and one research associate. CONCLUSIONS This consensus statement provides the guidance/recommendations for Indian practitioners regarding the use of OCP in women with PCOS. PCOS is one of the common endocrinopathies encountered in gynecological/endocrine practice. The spectrum of this disorder may range from prepubertal girls with premature pubarche, young girls with hirsutism, acne and anovulatory cycles, married women with infertility, and elderly women. Although obesity is a common feature for most PCOS patients, 'lean PCOS' also exists. For several years, OCPs have played an important role in the symptom management of PCOS women. This is due to the fact that OCPs decrease the luteinizing hormone, reduce androgen production, and increase sex hormone-binding globulin, which binds androgens. Several new formulations of OCPs have been developed to decrease the side effects. This includes use of less androgenic progestins and lower doses of ethinyl estradiol. These consensus recommendations help the health provider to choose the right type of OCPs, which will alleviate the symptoms with least side effects. It also gives insight into the indications, contraindications, and concerns regarding its short, intermediate and long-term use.

Abstract
Loss of efficacy of hormonal contraceptives is of particular concern for women who are overweight or obese. Only recently have clinical trials started to include overweight and obese women in their study populations, limiting the data available on which to make the best prescribing decisions for hormonal contraceptives for these patients. Other methods, such as the copper or levonorgestrel-containing intrauterine device, the etonogestrel implant, and depot medroxyprogesterone acetate, are preferred over combined oral contraceptives, the transdermal patch, and the vaginal ring.

Abstract
OBJECTIVE Obesity has increased dramatically in the United States in recent decades. Our objective was to explore associations of contraceptive choices of US women, aged 20-44years, with body mass index (BMI) and relevant covariates. STUDY DESIGN Data are based on interviews with a national sample of 11,300 women in the 2011-2015 National Survey of Family Growth. We analyzed women ages 20-44 at risk of unintended pregnancy. The primary dependent variable was BMI category. Covariates analyzed included age, parity, race/ethnicity, marital status, self-reported health and education. Data were analyzed via cross-tabulation and logistic regression. We determined unadjusted and adjusted odds ratios for three categories of contraceptive method: female sterilization, intrauterine device (IUD) and hormonal contraception. RESULTS Obese women have higher odds of female sterilization (BMI 30.0-34.9 kg/m2: adjusted odds ratio (aOR)=1.96, 95% confidence interval (CI) 1.45-2.66; BMI 35.0 kg/m2 and higher: aOR=1.56, 95% CI 1.13-2.14) compared to women with normal BMI. Odds of IUD use are significantly higher among women with BMI >35 kg/m2 (aOR=1.64, 95% CI 1.20-2.25). Odds of hormonal contraceptive use are correspondingly reduced (aOR=0.78, 95% CI 0.62-0.98) for women in the highest BMI category. CONCLUSIONS Contraceptive use varies by BMI category even after adjusting for usual correlates of use. Differences in contraceptive use by BMI category have implications for contraceptive counseling and provision. IMPLICATIONS Findings that obese women are more likely to rely on female sterilization raise questions about how weight concerns and obesity affect contraceptive decision making. Future research could explore associations between obesity and contraceptive use in adolescent women.

Abstract
INTRODUCTION Obese women have special safety requirements for contraceptive choice, but the evidence supporting such decision is dispersed and sometimes conflicting. Despite being effective, well tolerated and safe for most women, hormonal contraceptives are underused by obese women due to fear of contraceptive failure, weight gain and venous thrombosis. Areas covered: We performed a comprehensive literature search to identify studies about hormonal contraception in overweight and obese women, including safety concerns. We considered the safety of hormonal contraceptives for otherwise healthy obese women and for those with comorbidities such as hypertension, diabetes, vascular disease, or a history of deep venous thrombosis. Expert opinion: Over time there is no convincing evidence that obesity increases the risk of contraceptive failure. Hormonal contraceptive users may have a modest weight gain that is comparable to that of non-users. Current evidence supports the safe use of combined hormonal contraceptives by obese women after detailed clinical screening to exclude comorbidities that may contraindicate the use of estrogens. Progestin-only methods are generally safe, and long-acting reversible contraceptives hold the best combination of efficacy, safety and convenience for this group, although individualization is advisable.

Abstract
The transdermal patch provides an effective and convenient option for hormonal contraception. The patch currently on the US market contains 150 µg norelgestromin and 35 µg ethinylestradiol (EE). The 20 cm2 patch is applied once weekly for 3 weeks, followed by a patch-free week, for a 21–7 cycle. Typical failure rates are similar to that of combined oral contraceptives (COCs). Transdermal delivery results in less peaks and troughs of estrogen, but a higher total estrogen exposure compared with COCs. Though studies show mixed results, the risk of developing venous thromboembolism (VTE) is about twice as high with the patch as with COCs; however, the absolute risk of VTE remains low. The side effect profile is similar to that of COCs, with slightly higher rates of breast tenderness plus a unique adverse effect of application site reactions. Two new patches have been developed, one containing gestodene and EE in Europe and another containing levonorgestrel and EE. Overall, the patch provides an alternative to COCs for women who want autonomy and the benefit of not needing to take a pill daily, with similar efficacy and tolerability.

Abstract
BACKGROUND Whether providers who regularly provide family planning services consider contraceptive methods as unsafe for women with obesity is unknown. METHODS We analyzed questionnaire responses received from December 2009 to March 2010 from 635 office-based physicians and 1323 Title X clinic providers delivering family planning services, who were randomly sampled (response rate 65%) before the release of national evidence-based contraception guidelines. We examined provider and clinical setting characteristics and clinic patient demographics for association with provider misconceptions about safety of combined oral contraceptives (COCs), depot medroxyprogesterone acetate (DMPA), or intrauterine devices (IUDs) for women with obesity. If providers considered methods as unsafe or do not know, we categorized those responses as misconceptions. We used multivariable logistic regression to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). RESULTS A substantial proportion of respondents had misconceptions about the safety of COCs (31%), DMPA (24%), copper (Cu) (18%), and levonorgestrel (LNG)-IUDs (16%) for women with obesity. Provider type was associated with increased odds of misconceptions for all four methods compared with office-based obstetrician/gynecologists. Not having the method available onsite was associated with safety misconceptions of DMPA (aOR 1.90, 95% CI 1.07-3.36), Cu-IUD (aOR 4.19, 95% CI 1.51-11.61), and LNG-IUD (aOR 5.25, 95% CI 1.67-16.49). CONCLUSION While the majority of providers considered all four contraceptive methods safe for women with obesity, substantial proportions had misconceptions about safety of COCs, DMPA, and IUDs. Provider education, particularly among certain specialties, is needed to increase knowledge regarding moderate and highly effective contraceptive methods among this patient population.

Abstract
BACKGROUND Obesity has reached epidemic proportions around the world. Effectiveness of hormonal contraceptives may be related to metabolic changes in obesity or to greater body mass or body fat. Hormonal contraceptives include oral contraceptives (OCs), injectables, implants, hormonal intrauterine contraception (IUC), the transdermal patch, and the vaginal ring. Given the prevalence of overweight and obesity, the public health impact of any effect on contraceptive efficacy could be substantial. OBJECTIVES To examine the effectiveness of hormonal contraceptives in preventing pregnancy among women who are overweight or obese versus women with a lower body mass index (BMI) or weight. SEARCH METHODS Until 4 August 2016, we searched for studies in PubMed (MEDLINE), CENTRAL, POPLINE, Web of Science, ClinicalTrials.gov, and ICTRP. We examined reference lists of pertinent articles to identify other studies. For the initial review, we wrote to investigators to find additional published or unpublished studies. SELECTION CRITERIA All study designs were eligible. The study could have examined any type of hormonal contraceptive. Reports had to contain information on the specific contraceptive methods used. The primary outcome was pregnancy. Overweight or obese women must have been identified by an analysis cutoff for weight or BMI (kg/m(2)). DATA COLLECTION AND ANALYSIS Two authors independently extracted the data. One entered the data into RevMan and a second verified accuracy. The main comparisons were between overweight or obese women and women of lower weight or BMI. We examined the quality of evidence using the Newcastle-Ottawa Quality Assessment Scale. Where available, we included life-table rates. We also used unadjusted pregnancy rates, relative risk (RR), or rate ratio when those were the only results provided. For dichotomous variables, we computed an odds ratio with 95% confidence interval (CI). MAIN RESULTS With 8 studies added in this update, 17 met our inclusion criteria and had a total of 63,813 women. We focus here on 12 studies that provided high, moderate, or low quality evidence. Most did not show a higher pregnancy risk among overweight or obese women. Of five COC studies, two found BMI to be associated with pregnancy but in different directions. With an OC containing norethindrone acetate and ethinyl estradiol (EE), pregnancy risk was higher for overweight women, i.e. with BMI ≥ 25 versus those with BMI < 25 (reported relative risk 2.49, 95% CI 1.01 to 6.13). In contrast, a trial using an OC with levonorgestrel and EE reported a Pearl Index of 0 for obese women (BMI ≥ 30) versus 5.59 for nonobese women (BMI < 30). The same trial tested a transdermal patch containing levonorgestrel and EE. Within the patch group, obese women in the "treatment-compliant" subgroup had a higher reported Pearl Index than nonobese women (4.63 versus 2.15). Of five implant studies, two that examined the six-capsule levonorgestrel implant showed differences in pregnancy by weight. One study showed higher weight was associated with higher pregnancy rate in years 6 and 7 combined (reported P < 0.05). In the other, pregnancy rates differed in year 5 among the lower weight groups only (reported P < 0.01) and did not involve women weighing 70 kg or more.Analysis of data from other contraceptive methods indicated no association of pregnancy with overweight or obesity. These included depot medroxyprogesterone acetate (subcutaneous), levonorgestrel IUC, the two-rod levonorgestrel implant, and the etonogestrel implant. AUTHORS' CONCLUSIONS The evidence generally did not indicate an association between higher BMI or weight and effectiveness of hormonal contraceptives. However, we found few studies for most contraceptive methods. Studies using BMI, rather than weight alone, can provide information about whether body composition is related to contraceptive effectiveness. The contraceptive methods examined here are among the most effective when used according to the recommended regimen.We considered the overall quality of evidence to be low for the objectives of this review. More recent reports provided evidence of varying quality, while the quality was generally low for older studies. For many trials the quality would be higher for their original purpose rather than the non-randomized comparisons here. Investigators should consider adjusting for potential confounding related to BMI or contraceptive effectiveness. Newer studies included a greater proportion of overweight or obese women, which helps in examining effectiveness and side effects of hormonal contraceptives within those groups.

Abstract
Related to concerns about the role of obesity in the efficacy of contraceptive drugs, a review of the literature was carried out in regard to the pharmacokinetics of ethinyl estradiol and various progestins given by various routes of administration. Most studies show that obese women exhibit modestly lower plasma concentrations of these drugs (circa 30%) when given the same doses as normal-weight women. While the mechanism is uncertain, precedence in the literature suggests that this is due to body weight-related differences in metabolism rates. Confusing in some of the literature is that a few studies have reported erroneously calculated pharmacokinetic parameters after multiple dosing of oral contraceptives. A demonstration of appropriate pharmacokinetic methodology is provided.

Abstract
A rapid increase in obesity rates worldwide further underscores the importance of better understanding the pharmacokinetic alterations in this sub-population and the subsequent effects on pharmacotherapeutics. Pharmacokinetics of contraceptive steroids is altered in obese oral contraceptive users, which may in turn impact efficacy. Our study has identified several dosing strategies that offset these pharmacokinetic changes and may improve effectiveness for obese oral contraception users.

Abstract
As the proportion of women with obesity increases worldwide, understanding the influence of body weight on sexual behavior, fertility, and contraceptive effectiveness is critical for health-care professionals and patients. Although many have theorized that obese women are different from normal-weight women regarding sexual health and behavior, current evidence for the most part disproves this. The exception is in adolescents where body image may play a role in riskier behavior, placing them at a greater risk of an unintended pregnancy. Given that most modern contraceptives were not originally evaluated in obese women, understanding how weight affects contraceptive pharmacokinetics and efficacy should be a focus of ongoing research. Evidence is reassuring that most modern contraceptive methods are safe and effective in obese women. This paper reviews what is known about sexual and contraceptive behavior, as well as the effectiveness and pharmacokinetics of modern contraceptives, for overweight and obese women.

[PMID: 24457062 DOI: 10.1016/j.contraception.2013.12.009] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2013] [Revised: 12/17/2013] [Accepted: 12/19/2013] [Indexed: 11/22/2022]
Abstract
OBJECTIVE The objective was to identify predictors of adherence to hormonal contraceptives in a female veteran population. STUDY DESIGN This was a retrospective cohort study of female veterans from the VA San Diego Healthcare System. The study period was April 1, 2010, to March 31, 2012. Each patient was followed for 1 year from the index date, defined as the date of first contraceptive prescription in the study time period. Adherence was defined as a medication possession ratio ≥ 0.9. Income was estimated using zip-code-based median household income and split into quintiles (quintile 1 being the lowest-earning group). Logistic regression was used to analyze the association between adherence and the independent variables. RESULTS A total of 805 patients were included in the final analysis. The majority of the population was white (62.2%) and receiving a 3-month supply of medication (87.6%). The following independent variables were predictive of increased adherence: 3-month supply versus 1-month supply [odds ratio (OR) 1.79, 95% confidence interval (CI) 1.03-3.13], age group 40-45 versus 18-24 (OR 2.57, 95% CI 1.16-5.70) and income quintiles 3 (OR 1.96, 95% CI 1.16-3.29), 4 (OR 1.77, 95% CI 1.06-2.98) and 5 (OR 1.75, 95% CI 1.03-2.98) each versus quintile 1 as reference group. The following were associated with decreased adherence: new start versus continuing user (OR 0.25, 95% CI 0.18-0.37), OB/GYN provider versus primary care provider (OR 0.60, 95% CI 0.38-0.95), and highest weight group versus lowest weight group (OR 0.40, 95% CI 0.17-0.94). CONCLUSION Hormonal contraceptive adherence in the veteran population is below optimal. Providing 3-month supplies of high-value therapies such as hormonal contraceptives is one strategy that may improve adherence. Initiatives to target lower socioeconomic status or new start populations to increase contraceptive adherence should also be considered. IMPLICATIONS Adherence to hormonal contraceptives is not as well studied in the literature as some other high-value therapies. Identifying predictive variables for adherence may have implications for establishing possible interventions, or refining benefit structures, in order to increase adherence.

Abstract
Obesity is a major public health concern affecting an increasing proportion of reproductive-aged women. Avoiding unintended pregnancy is of major importance, given the increased risks associated with pregnancy, but obesity may affect the efficacy of hormonal contraceptives by altering how these drugs are absorbed, distributed, metabolized or eliminated. Limited data suggest that long-acting, reversible contraceptives maintain excellent efficacy in obese women. Some studies demonstrating altered pharmacokinetic parameters and increased failure rates with combined oral contraceptives, the contraceptive patch and emergency contraceptive pills suggest decreased efficacy of these methods. It is unclear whether bariatric surgery affects hormonal contraceptive efficacy. Obese women should be offered the full range of contraceptive options, with counseling that balances the risks and benefits of each method, including the risk of unintended pregnancy.

The creeping Pearl: Why has the rate of contraceptive failure increased in clinical trials of combined hormonal contraceptive pills? Contraception 2013; 88:604-10. [PMID: 23683581 DOI: 10.1016/j.contraception.2013.04.001] [Citation(s) in RCA: 46] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2013] [Revised: 04/04/2013] [Accepted: 04/07/2013] [Indexed: 11/23/2022]
Abstract
BACKGROUND Despite several drawbacks, the Pearl Index continues to be the most widely used statistical measure of contraceptive failure. However, Pearl indices reported in studies of newer hormonal contraceptives appear to be increasing. STUDY DESIGN We searched PubMed and Medical Intelligence Solutions databases for prospective trials evaluating oral contraceptive (OC) efficacy to examine potential factors that could contribute to increasing Pearl indices. RESULTS Numerous potential factors were identified, including an increased rate of failures of newer OCs, deficiencies in methods of calculating contraceptive failure rates, differences in study design and changes in patient populations resulting in increased rates of contraceptive failures due to the inappropriate or inconsistent use of the method. CONCLUSIONS The two most likely important contributors to the increase in Pearl indices are more frequent pregnancy testing with more sensitive tests and less adherent study populations. Because study populations appear to be increasingly representative of the likely actual users once the product is marketed, we can expect to see even higher failure rates in ongoing and future studies. This result poses challenges for companies and regulatory agencies.
