Abstract
The 2024 U.S. Medical Eligibility Criteria for Contraceptive Use (U.S. MEC) comprises recommendations for the use of specific contraceptive methods by persons who have certain characteristics or medical conditions. These recommendations for health care providers were updated by CDC after review of the scientific evidence and a meeting with national experts in Atlanta, Georgia, during January 25-27, 2023. The information in this report replaces the 2016 U.S. MEC (CDC. U.S. Medical Eligibility Criteria for Contraceptive Use, 2016. MMWR 2016:65[No. RR-3]:1-103). Notable updates include 1) the addition of recommendations for persons with chronic kidney disease; 2) revisions to the recommendations for persons with certain characteristics or medical conditions (i.e., breastfeeding, postpartum, postabortion, obesity, surgery, deep venous thrombosis or pulmonary embolism with or without anticoagulant therapy, thrombophilia, superficial venous thrombosis, valvular heart disease, peripartum cardiomyopathy, systemic lupus erythematosus, high risk for HIV infection, cirrhosis, liver tumor, sickle cell disease, solid organ transplantation, and drug interactions with antiretrovirals used for prevention or treatment of HIV infection); and 3) inclusion of new contraceptive methods, including new doses or formulations of combined oral contraceptives, contraceptive patches, vaginal rings, progestin-only pills, levonorgestrel intrauterine devices, and vaginal pH modulator. The recommendations in this report are intended to serve as a source of evidence-based clinical practice guidance for health care providers. The goals of these recommendations are to remove unnecessary medical barriers to accessing and using contraception and to support the provision of person-centered contraceptive counseling and services in a noncoercive manner. Health care providers should always consider the individual clinical circumstances of each person seeking contraceptive services. This report is not intended to be a substitute for professional medical advice for individual patients; when needed, patients should seek advice from their health care providers about contraceptive use.

Abstract
OBJECTIVE Assess the association between combined hormonal contraceptives (CHC) use and musculoskeletal tissue pathophysiology, injuries or conditions. DESIGN Systematic review with semiquantitative analyses and certainty of evidence assessment, guided by the Grading of Recommendations Assessment, Development and Evaluation approach. DATA SOURCES MEDLINE, EMBASE, CENTRAL, SPORTDiscus, CINAHL searched from inception to April 2022. ELIGIBILITY Intervention and cohort studies that assessed the association between new or ongoing use of CHC and an outcome of musculoskeletal tissue pathophysiology, injury or condition in postpubertal premenopausal females. RESULTS Across 50 included studies, we assessed the effect of CHC use on 30 unique musculoskeletal outcomes (75% bone related). Serious risk of bias was judged present in 82% of studies, with 52% adequately adjusting for confounding. Meta-analyses were not possible due to poor outcome reporting, and heterogeneity in estimate statistics and comparison conditions. Based on semiquantitative synthesis, there is low certainty evidence that CHC use was associated with elevated future fracture risk (risk ratio 1.02-1.20) and total knee arthroplasty (risk ratio 1.00-1.36). There is very low certainty evidence of unclear relationships between CHC use and a wide range of bone turnover and bone health outcomes. Evidence about the effect of CHC use on musculoskeletal tissues beyond bone, and the influence of CHC use in adolescence versus adulthood, is limited. CONCLUSION Given a paucity of high certainty evidence that CHC use is protective against musculoskeletal pathophysiology, injury or conditions, it is premature and inappropriate to advocate, or prescribe CHC for these purposes. PROSPERO REGISTRATION NUMBER This review was registered on PROSPERO CRD42021224582 on 8 January 2021.

Abstract
ABSTRACT Redinger, AL and Baker, BS. Oral contraceptives and female rowers' skeletal health. J Strength Cond Res 37(3): 669-677, 2023-Previous studies suggest that women using oral contraceptives (OC) experience fewer skeletal benefits from exercise compared with non-OC users. These findings may be especially important for athletes competing in weight-supported sports with a high prevalence of low bone mineral density and fracture, such as rowing. The purpose of this study was to examine skeletal health and bone injuries in collegiate female rowers. Forty-nine National Collegiate Athletic Association Division I female rowers completed general health, menstrual history, and bone physical activity questionnaire (BPAQ) surveys. Dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) scans were used to assess bone content, density, and geometry. Contraceptive (OC users n = 14, non-OC users n = 35) and self-reported stress fracture (SFx n = 11, None n = 38) groups were analyzed using analysis of covariance and independent t -tests. Additionally, effect sizes ( d ) were calculated and significance was set at p ≤ 0.05. Oral contraceptive users had reduced lumbar spine areal bone mineral density after adjustment for Total BPAQ ( d = 0.58; p = 0.041) compared with non-OC users, but all other total body and site-specific DXA measures of bone mineral content and density were similar between contraceptive and injury groups. When comparing bone geometry of the 4, 38, and 66% tibiae using pQCT, no significant differences were found after adjustment for either contraceptive or injury group (all p > 0.060). Our findings suggest that OC usage was not associated with reduced skeletal health in competitive female rowers as evidenced by all Z-scores being above -2.0 and similar bone indices of mineralized content, density, geometry, and estimated strength between the groups.

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.

Discontinuation of leisure time impact-loading exercise is related to reduction of a calcaneus quantitative ultrasound parameter in young adult Japanese females: a 3-year follow-up study. Osteoporos Int 2014; 25:485-95. [PMID: 23794043 DOI: 10.1007/s00198-013-2416-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2012] [Accepted: 06/10/2013] [Indexed: 11/30/2022]
Abstract
UNLABELLED A 3-year follow-up study on 334 young Japanese females enrolled in a university at the age of 18 years revealed that discontinuation of leisure time impact-loading exercises performed in junior high and/or high school was associated with increased risk of reduction in calcaneus osteo-sono assessment index (OSI). INTRODUCTION Bone strength rapidly increases during puberty and reaches its peak by the end of adolescence. The aim of this study was to determine the lifestyle factors that influence the maintenance of calcaneus OSI in young adult females around the time when peak bone mass is attained. METHODS Annual health checkups including OSI measurements, anthropometrics, lifestyle analysis, and blood examination were performed 4 times on 334 Japanese females enrolled in a university at the age of 18 years. According to the slope of OSI change during the 3-year follow-up, the subjects were grouped into two categories: OSI loss (the lowest tertile) and OSI gain/stable (the second and third tertiles). RESULTS At the baseline assessment, the OSI loss group had higher OSI and height and an earlier menarche age than the OSI gain/stable group. Performing leisure time impact-loading exercise in junior high and/or high school but discontinuing it at university was associated with increased risk of OSI loss, independent of OSI, height and weight at the age of 18 years, weight change during follow-up, age of menarche, energy-adjusted nutrient intake, and alcohol drinking; the odds ratios were 4.1-4.9 compared with those performing impact-loading exercise at university. In particular, duration, frequency, and subjective intensity of impact-loading exercise during high school were positively associated with OSI loss. CONCLUSION Discontinuation of leisure time impact-loading exercises performed during late adolescence is associated with an increased risk of OSI loss in young adult females during the 3-year follow-up period.

Abstract
➤ Cigarette smoking decreases bone mineral density and increases the risk of sustaining a fracture or tendon injury, with partial reversibility of these risks with long-term cessation of smoking. ➤ Cigarette smoking increases the risk for perioperative complications, nonunion and delayed union of fractures, infection, and soft-tissue and wound-healing complications. ➤ Brief preoperative cessation of smoking may mitigate these perioperative risks. ➤ Informed-consent discussions should include notification of the higher risk of perioperative complications with cigarette smoking and the benefits of temporary cessation of smoking.

Abstract
STUDY OBJECTIVES This study aims to explore the association between osteoporosis and nightly sleep duration among adult outpatients. DESIGN This is a large-scale, retrospective cross-sectional study. SETTING The setting was in a preventive medicine health center at a general community hospital in Tokyo, Japan. PARTICIPANTS There were 19,321 healthy individuals (≥50 years old) who underwent annual general health checkup between January and December 2008. MEASUREMENTS The participants were divided into four groups according to their self-reported average nightly sleep duration (<6, 6-6.9, 7-7.9, and >8 h). Radial bone mineral density was measured using dual-energy X-ray absorptiometry, and T-score was compared to young adult mean to diagnose osteoporosis. Multivariate logistic regression was used to explore the association between sleep duration and osteoporosis. RESULTS The mean age of the participants was 60.9 years (standard deviation [SD], 7.9) and 48.0% were female. The prevalence of osteoporosis was 8.0% (95% confidence interval [CI] = 7.6-8.4%). Those with sleep duration of >8 h were more likely to have osteoporosis (odds ratio [OR] = 1.35; 95% CI = 1.06-1.73) than those with short sleep duration (<6 h). CONCLUSION Those individuals with self-reported sleep duration of more than 8 h (long sleepers) appear to have higher odds of osteoporosis compared to the progressively shorter sleepers.

Abstract
Tobacco cigarette smoking causes many negative effects on the body, and it is the leading preventable cause of death in the United States. These negative effects are a concern for the foot and ankle surgeon, as smoking can increase the risk of diabetes and peripheral artery disease and delay healing of surgical incisions and ulcerations of the lower extremities. Tobacco cigarette smoking can also increase the risk of avascular necrosis and delayed union and nonunions of fractures and osteotomies. Smoking cessation is an important component in the overall treatment of conditions affecting the foot and ankle. Smoking cessation can be a difficult goal to achieve, but proper education and support can help patients reach this goal.

Abstract
The associations of oral contraceptive use and cognitive dietary restraint with bone speed of sound (SOS) and bone turnover were investigated in 100 Canadian university-aged women (18–25 years old). Dietary restraint was assessed using the Dutch Eating Behavior Questionnaire (DEBQ) and daily calcium intake (Ca++) was assessed by the rapid assessment method. Quantitative ultrasound was used to measure SOS at the tibia and radius. Bone formation was estimated from plasma osteocalcin (OC), 25-OH vitamin D, and serum bone-specific alkaline phosphatase (BAP). Bone resorption was determined from serum cross-linked N-teleopeptide of type I collagen (NTx) and plasma C-terminal telopeptide of type I collagen (CTx). Weekly physical activity energy expenditure (WAeq) was assessed using a standardized questionnaire, and height, body mass, relative body fat (%BF), and chest, waist, and hip circumferences were also measured. Participants were divided into low and moderate to high dietary restrainers (LDRs and MDRs, respectively). These groups were further sub-divided into users and non-users of oral contraceptives. All groups had similar age at menarche, body composition, WAeq, and equally low levels of Ca++and vitamin D. Within the non-users of oral contraceptives, MDR exhibited a lower tibial SOS (p ≤ 0.024) and OC (p ≤ 0.009) than LDR. Moreover, amongst the LDR, the oral contraceptive users had a lower tibial SOS (p ≤ 0.015) and BAP (p ≤ 0.002) than non-users. These results show that bone SOS and bone turnover were influenced by oral contraceptives and cognitive dietary restraint among this population of young women independent of body composition and physical activity.

Abstract
BACKGROUND Estrogen-progestin contraception may affect estrogen production and alter the development of peak bone mass. STUDY DESIGN A 4-year follow-up with 122 adolescent women aged 12-19 years. The data were divided into three groups based on estrogen-progestin contraceptive (EPC) use: (i) nonusers (n=52), (ii) 1-2 years of use (n=24) and (iii) use for more than 2 years (n=46). The estrogen dose of the preparations was < or =35 mcg. Height, weight, and the amount of exercise (ratio of work metabolic rate, h/week) as well as bone mineral content (BMC) of lumbar spine and femoral neck were measured repeatedly. RESULTS There was a significant trend showing less of an increase in the mean adjusted BMC of lumbar spine in the group of adolescent women who had used EPC for more than 2 years compared with the two other groups. In the mean adjusted BMC of the femoral neck, there was a significant trend of a smaller increase in EPC users for more than 2 years compared with 1-2 years of use. CONCLUSIONS Long-term EPC with low-dose estrogen preparations seems to suppress normal bone mineral accrual in adolescent women.

Abstract
The aim of this cross-sectional analysis was to examine the skeletal effects of low-dose monophasic oral contraceptive (OC) use in a cohort of 248 young Caucasian women aged 18-24 years. Areal bone mineral density (BMD) of the femoral neck and lumbar spine was evaluated by dual-energy X-ray absorptiometry. Volumetric BMD, bone mineral content (BMC), and bone geometry were assessed in the tibia by peripheral quantitative computed tomography (pQCT). The women were allocated into ever or never OC users, and also into 5 different OC groups according to duration and time of initiation of OC use. Women with >2 years of OC use and OC initiation within 3 years after menarche were characterized by 10% lower femoral neck areal BMD (P<0.001), 5% lower spine areal BMD (not significant, P=0.101), 7% lower distal tibial total BMC (P<0.05), and 6% lower total BMC at the tibial shaft (P<0.05) relative to never users. In addition, women who had ever used OCs had lower bone mass at the femoral neck and tibial shaft, despite similar age, height, weight, BMI, hours of exercise, and calcium intake compared with never users. At the tibial shaft, OC users showed reduced total cross-sectional area, and increased cortical BMD. In conclusion, our data suggest that OC use is associated with a detrimental effect on bone mass in young women, and provide further insight into the pathophysiological mechanisms involved.

Abstract
AIM This 12-month study was conducted to evaluate the skeletal effects of two monophasic oral contraceptives containing 20 mug of ethinylestradiol and 100 mug of levonorgestrel (LEVO) or 150 mug of desogestrel (DESO). METHODS Fifty-two women (18-24 years) were randomized into the DESO group or the LEVO group; 36 women served as controls. The areal bone mineral density (aBMD) of the femoral neck and the lumbar spine was evaluated by DXA, and parameters of bone geometry and volumetric bone mineral density (vBMD) were assessed by peripheral quantitative computed tomography at the distal radius and the tibia. RESULTS The LEVO group did not lose vertebral aBMD, whereas women in the DESO group lost 1.5%. At the distal radius and the tibia (shank level, 14%), LEVO induced an increase in total cross-sectional area, indicating increased periosteal bone formation. Radial trabecular vBMD declined by 1.4+/-1.8% in the DESO group, while it remained unchanged in the LEVO group. CONCLUSION Our study suggests that the skeletal effects of OC preparations may be influenced by progestogenic components in young women.

Abstract
Hormone replacement therapy, once the gold standard for treatment of osteoporosis, is no longer a clinical option. Effective alternatives are available using resistance exercise and supplementation with calcium and vitamin D to ameliorate bone loss and promote new bone formation. This article summarizes current evidence and provides recommendations for community health nurses to develop effective plans for prevention and treatment of osteoporosis.

Martins SL, Curtis KM, Glasier AF. Combined hormonal contraception and bone health: a systematic review. Contraception 2006; 73:445-69. [PMID: 16627030 DOI: 10.1016/j.contraception.2006.01.003] [Citation(s) in RCA: 61] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2005] [Accepted: 01/05/2006] [Indexed: 11/17/2022]
Abstract
This systematic review examined whether women who use combined hormonal contraception experience changes in risk of fracture or bone mineral density (BMD) that differ from nonusers. We identified 86 articles from PubMed and EMBASE (published 1966 to August 2005) that reported on fracture or BMD outcomes by use of combined hormonal contraceptives. The evidence relating to combined oral contraceptives (COCs) and fracture is inconclusive, as results from the available studies conflict. Studies of adolescent and young adult women generally found lower BMD among COC users than nonusers. Evidence for premenopausal adult women suggested no differences in BMD between COC users and nonusers. COC use in perimenopausal and postmenopausal women preserved bone mass, while nonusers lost BMD, but BMD among former COC users in this age group was the same as for never-users. Evidence for other combined hormonal methods was very limited, with one study indicating no effect of combined hormonal injectable use among premenopausal women on BMD and one study suggesting lower BMD among premenopausal users of the NuvaRing than in nonusers.

Elgán C, Fridlund B. Bone mineral density in relation to body mass index among young women: a prospective cohort study. Int J Nurs Stud 2005; 43:663-72. [PMID: 16343501 DOI: 10.1016/j.ijnurstu.2005.10.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2005] [Revised: 09/13/2005] [Accepted: 10/29/2005] [Indexed: 12/01/2022]
Abstract
AIM To identify important predictors among lifestyle behaviours and physiological factors of bone mineral density (BMD) in relation to body mass index (BMI) among young women over a 2-year period. DESIGN, SAMPLE AND MEASUREMENTS: Data were collected in 1999 and 2001. Healthy young women (n=152) completed a questionnaire. BMD measurements were performed by DEXA in the calcaneus. The women were subdivided into three categories according to baseline BMI. RESULTS Baseline bodyweight explained 25% of the variability in BMD at follow-up in the BMI<19 category, and high physical activity seemed to hinder BMD development. In the BMI>24 category, a difference in time spent outdoors during winter between baseline and follow-up was the single most important factor for BMD levels. Overweight women with periods of amenorrhoea had lower BMD than overweight women without such periods. CONCLUSIONS Predictors and lifestyle behaviours associated with BMD are likely to be based on women of normal weight. BMI should be considered when advising on physical activity, since high physical activity seems to impair BMD development among underweight young women, possibly due to energy imbalance. Among overweight women, sleep satisfaction is the greatest predictor associated with BMD change and may indicate better bone formation conditions. Energy balance and sleep quality may be prerequisites of bone health and should be considered in prevention.
