Selection, Initiation, Continuation, and Efficacy of Reversible Contraception Among Enlisted U.S. Service Women in Their First Term of Service From 2012 to 2020.

BACKGROUND: Pregnancy is the second most common cause of limited duty days among active duty service members in the U.S. Military. Pregnancy accounts for 10% of all days on restricted duty, despite impacting a minority of active duty service members. One out of five service women will experience an unintended pregnancy every year despite the availability of no-cost contraception and reproductive healthcare. Young, single, junior enlisted service women experience the highest rate of unintentional pregnancy. Previous studies have demonstrated service branch-based variability in selection, initiation, and continuation of specific contraceptive methods related to service branch culture and access to contraception during basic training. It is unclear if these differences impact overall contraception use or fertility rates among junior enlisted service women in their first term of enlistment. This study examines rates of contraceptive selection, initiation, continuation, and efficacy among junior enlisted service women in their first 4-year enlistment period, and the service branch specific variability in these outcomes. METHODS: This study is a secondary analysis of Military Healthcare Data Repository records from women who began basic training between 2012 and 2020 and remained on active duty for at least 12 months. We used Kaplan-Meier analyses to examine the effect of age and military branch on contraceptive continuation and efficacy. We used binomial regression for interval censored data, to assess the association of service branch with rates of contraceptive initiation, contraception use, births, and childbirth-related duty restrictions. RESULTS: We identified 147,594 women who began basic training between 2012 and 2020. The mean age of these women at the beginning of basic training was 20.4 ± 3.1 years. Women in the marines and navy had higher contraceptive initiation rates than women in the army or air force. Among women initiating a contraceptive pill, patch, or ring (short-acting reversible contraception), 58.3% were still using some form of hormonal contraception 3 months later. Among women initiating depot-medroxyprogesterone (DMPA), 38.8% were still using any form of hormonal contraception 14 weeks later. Long-acting reversible contraceptive methods, such as intrauterine or subdermal contraceptives, had higher continuation rates and less service-based variability in continuation and failure rates than short-acting reversible contraception or depot-medroxyprogesterone. The proportion of days on any form of prescription contraception during the first 4 years on active duty varied from 23.3% in the army to 38.6% in the navy. The birth rate varied from 34.8 births/1,000 woman-years in the air force up to 62.7 births/1,000 woman-years in the army. Compared with women in the air force, women in the army experienced 2,191 additional days of postpartum leave and 13,908 days on deployment restrictions per 1,000 woman-years. DISCUSSION: Service branch specific variability in contraceptive use is associated with differences in days of pregnancy-related duty restrictions during first 4 years on active duty among junior enlisted females. Robust implementation of best practices in contraceptive care across the military health system to improve contraceptive initiation and continuation appears to offer an opportunity to improve military readiness and promote the health and well-being of active duty service women, particularly in the army.

Brief report: Influence of mandatory contraceptive education emphasizing long-acting reversible methods on continuation rates among military recruits.

OBJECTIVES: Determine if the replacement of patient-initiated, individual contraceptive education with mandatory group contraceptive education, during US Navy basic training, was associated with decreased LARC continuation. STUDY DESIGN: Secondary analysis of administrative billing data from female military recruits who began basic training between September 2012 and February 2020. RESULTS: Servicewomen who started LARC method during rather than after basic training had higher continuation rates. Servicewomen who started training before the implementation of mandatory group education had higher IUD continuation than those trained after. CONCLUSIONS: Implementation of mandatory group contraceptive education during basic training was not associated with a decline in LARC continuation.

Mandatory HPV Vaccination; Opportunity to Save Lives, Improve Readiness and Cut Costs.

Human papillomavirus (HPV) is the most common sexually transmitted infection (STI) in the U.S. military and accounts for more healthcare visits than the next two most common STIs combined. Human papillomavirus is preventable with a safe, effective, prophylactic vaccine that has been available since 2006, yet vaccination rates remain low. The vaccine is approved for females and males aged 9-45 years for prevention of HPV-related dysplasia and cancers. Although it is recommended by the Centers for Disease Control and Prevention (CDC)'s Advisory Committee on Immunization Practices (ACIP), it is not part of the U.S. military's mandatory vaccine list. Human papillomavirus does not just affect female service members-male service members have a higher reported seropositive rate than their civilian counterparts and can develop oropharyngeal, anal, or penile cancers as sequelae of HPV. Oropharyngeal cancer, more common in males, is the fastest growing and most prevalent HPV-related cancer in the USA. Several countries, such as Australia and Sweden, have successfully implemented mandatory vaccine programs and have seen rates of HPV-related diseases, including cancer, decline significantly. Some models project that cervical cancer, which is the fifth-most common cancer in active duty women, will be eliminated in the next 20 years as a result of mandatory vaccination programs. Between higher seropositive rates and lack of widespread vaccination, HPV dysplasia and cancer result in lost work time, decreased force readiness, negative monetary implications, and even separation from service. With more than half of the 1.3 million service members in the catch-up vaccination age range of less than 26 years of age, we are poised to have a profound impact through mandatory active duty service member vaccination. Although multiple strategies for improving vaccination rates have been proposed, mandatory vaccination would be in line with current joint service policy that requires all ACIP-recommended vaccines. It is time to update the joint service guidelines and add HPV vaccine to the list of mandatory vaccines.

Race matters: maternal morbidity in the Military Health System.

BACKGROUND: In the United States, Black women are 3 to 4 times more likely to die from childbirth and have a 2-fold greater risk of maternal morbidity than their White counterparts. This disparity is theorized to be related to differences in access to healthcare or socioeconomic status. Military service members and their dependents are a diverse community and have equal access to healthcare and similar socioeconomic statuses. OBJECTIVE: This study hypothesized that universal access to healthcare, as seen in the military healthcare system, leads to similar rates of maternal morbidity regardless of race or ethnic background. STUDY DESIGN: A retrospective cohort study included data from the inaugural National Perinatal Information Center special report comparing indicators of severe maternal morbidity by race. National Perinatal Information Center data from participating military treatment facilities in the Department of Defense performing more than 1000 deliveries annually from April 1, 2018, to March 31, 2019, were included. Using this convenience data set, Chi-square analyses comparing the percentages of cesarean deliveries, adult intensive care unit admissions, and severe maternal morbidity between Black and White patients were performed. RESULTS: Black women were more likely to deliver via cesarean delivery (31.68% vs 23.58%; P<.0001; odds ratio, 1.5; 95% confidence interval, 1.38-1.63), be admitted to an adult intensive care unit (0.49% vs 0.18%; P=.0026; odds ratio, 2.78; 95% confidence interval, 1.46-5.27), and experience overall severe maternal morbidity (2.66% vs 1.66%; P=.0001; odds ratio, 1.67; 95% confidence interval, 1.3-2.15) even when excluding blood transfusion (0.64% vs 0.32%; P=.0139; odds ratio, 1.99; 95% confidence interval, 1.17-3.36) than their White counterparts. There were no substantial differences between races in overall severe maternal morbidity associated with postpartum hemorrhage even when excluding blood transfusion in this subset. CONCLUSION: Equal access to healthcare and similar socioeconomic statuses in the military healthcare system do not explain the healthcare disparities seen regarding maternal morbidity encountered by Black women having children in the United States. This study identifies healthcare disparities in severe maternal morbidity among active duty service members and their families. Further studies to assess causes such as systemic racism (including implicit and explicit medical biases) and physiological factors are warranted.

Extending Peer Support Across the Military Health System to Decrease Clinician Burnout.

INTRODUCTION: Clinician burnout is widespread throughout medicine, affecting professionalism, communication, and increases the risk of medical errors, thus impacting safe quality patient care. Previous studies have shown Peer Support Programs (PSPs) promote workforce wellness by supporting clinicians during times of heightened stress and vulnerability. Although these programs have been implemented in large institutions, they have not been used in military hospitals, which have high staff turnover and added stressors of deployments. MATERIALS AND METHODS: In December 2018, 50 physicians received 5 hours of PSP training at a military hospital from a nationally recognized PSP expert, following the programmatic structure described by Shapiro and Galowitz (2016). Utilization of the program was tracked from December 2018 to December 2019, recording only classification of provider type, triggering event, and provider specialty to maintain confidentiality. Qualitative comments from recipients and supporters were saved anonymously for quality improvement purposes. RESULTS: In the first year of our PSP, 254 clinicians (102 [40.2%] residents/fellows, 91 [35.8%] staff physicians, 4 [1.6%] medical students, 35 [13.8%] nurses, 22 [8.7%] allied health) received 1:1 peer support. Primary specialties utilizing peer support included 135 (52.9%) medical, 59 (23.2%) surgical, 43 (16.9%) obstetric, and 18 (7.1%) pediatric. Patient death (25%), risk management notification (22%), medical error/complication (15%), and poor patient outcome (13%) were the most common events triggering peer support. Peer support was provided at 8 locations across the continental United States with universally positive comments from recipients. CONCLUSIONS: Implementation of a PSP at our institution led to rapid utilization across multiple hospitals in the military health system, a model that could easily expand to deployed settings and remote locations. Access to peer support across the military health system could both mitigate the increased risks of military clinician burnout, and improve patient safety, healthcare worker resilience, and service member readiness.

Differences in Rate of Gestational Diabetes Between Active Duty and Non-active Duty Beneficiaries at a Military Treatment Facility.

INTRODUCTION: Gestational diabetes mellitus (GDM) affects approximately 1-14% of all pregnancies in the United States and has significant maternal and neonatal consequences. Developing GDM can increase a patient's risk of developing overt diabetes in the future which may impact a soldier's readiness. The purpose of this study is to compare the incidence of GDM in active duty females compared with civilian dependents. MATERIALS AND METHODS: This retrospective cohort analysis was performed at a military medical center with IRB approval. Active duty and dependent status women who delivered between June 1, 2014 and April 30, 2015 were identified along with incidence of GDM. Sample size calculation determined a need for 391 women in each group to observe a 5% difference in rate of GDM with a power of 80%. Chi-squared analysis was used to compare rates of GDM. RESULTS: Rates of GDM were similar between the two cohorts (active duty = 9.95%, dependent = 9.72%, P = .91). Age, gravidity, and prepregnancy BMI were also similar between groups. The rate of diet-controlled GDM were different between the two cohorts (active duty = 53.8%, dependent = 34.2%, P = .02). CONCLUSIONS: This study highlights active duty females have similar rates of GDM as dependents. Gestational diabetes mellitus is known to affect short- and long-term maternal and neonatal outcomes and can impact a soldier's readiness. Further research is required to determine the long-term impact of GDM in active duty females and best practices to decrease rates of GDM in the military population.

Influence of military contraceptive policy changes on contraception use and childbirth rates among new recruits.

BACKGROUND: Unplanned pregnancy is a common problem among United States servicewomen. Variation among service branches in contraceptive education and access during initial training is associated with differences in contraceptive use and childbirth rates despite access to a uniform health benefit including no-cost reproductive healthcare and contraception. However, it is unclear whether changes in branch-specific contraceptive policies can influence reproductive outcomes among junior enlisted women in that service branch. OBJECTIVE: To assess the longitudinal effect of contraceptive policy changes on contraception use and childbirth rates among military recruits. MATERIALS AND METHODS: Secondary analysis was performed of insurance records from 70,852 servicewomen who started basic training between October 2013 and December 2016, assessing the longitudinal impact of a Navy policy change expanding contraceptive access during basic training implemented in January 2015, and a Marine Corps policy change restricting contraceptive access during basic training implemented in January 2016 on the following: contraception use (pills, patches, rings, injectable, implantable, and intrauterine) at 6 months, long-acting reversible contraception use at 6 months, and childbirth prior to 24 months after service entry. We used logistic and Cox regression models, adjusted for age group, to compare outcomes of women in the Navy and Marine Corps who started basic training before and after their service branch's policy change with outcomes among women in the Army and Air Force. RESULTS: Compared to the longitudinal difference observed among women attending Army or Air Force basic training, changing policies to increase contraceptive access during Navy basic training in January 2015 increased contraception use from 33.1% of sailors to 39.2% of sailors before and after the policy change (interaction term odds ratio, 1.31; 95% confidence interval, 1.22-1.41) and long-acting reversible contraception use 11.0% to 22.7% (odds ratio, 1.78; 95% confidence interval, 1.50-2.08). However, this policy change was not associated with a decline in childbirth rates among sailors (7.5% versus 6.1%) relative to the change among women in the Army and Air Force over the same time period (interaction term hazard ratio, 0.90; 95% confidence interval, 0.79-1.03). The January 2016 Marine Corps policy change decreased contraception use (29.6% to 24.4%; odds ratio, 0.78; 95% confidence interval, 0.70-0.88), long-acting reversible contraception use 14.6% to 7.3% (odds ratio, 0.39; 95% confidence interval, 0.31-0.48), and increased childbirth rates (8.0% to 9.6%; hazard ratio, 1.26; 95% confidence interval, 1.03-1.55) among Marines compared to outcomes in the Army and Air Force over the same time period. CONCLUSION: Basic training contraceptive policy influences contraception use among junior enlisted servicewomen. Implementing best practices across the military may increase contraception use and decrease childbirth rates among junior enlisted servicewomen.

Development of In-situ Simulation Lab for Training Gynecology Residents in Basic Laparoscopic and Hysteroscopic Operative Skills.

INTRODUCTION: Mounting evidence suggests that practice on simulators leads to improved operative skills and patient safety. With restrictions on resident work hours resulting in less exposure to procedures, simulation is the key to developing operative skills during residency and beyond. Residency programs struggle with implementing a simulation program due to timing and availability of residents. Despite having a large centralized simulation space at our institution, we identified lack of dedicated gynecologic simulation curriculum and simulator accessibility as our greatest barriers to utilizing simulation training in gynecology resident education. We sought to design a space within the resident work area dedicated to gynecologic simulation training with specific curriculum and objectives for each work station based on residency year level. METHODS: We created four workstations in a room within the Ob/Gyn clinic, in close proximity to the resident offices. Two virtual reality simulators, the LapVR (CAE, Montreal, Canada) ($84,996.00) and Simbionix Hystsim (3D Systems, (formerly Simbionix), CO, USA) ($95,741.10), were acquired from our institution's simulation center and placed in this training space to allow for enhanced resident access. The two other work stations consisted of an FLS trainer box and monitor ($1580) and another low fidelity laparoscopic box trainer and monitor ($450). Specific objectives for each station with corresponding evaluation checklists were written for each residency year level. Dedicated time to meet the written objectives was given to residents each week during their benign gynecology rotation. Supervision and assistance with task completion was provided by staff mentors assigned during those shifts. RESULTS: Residents who had this simulation lab available to them during their gynecology rotation participated in a minimum of seven hours of simulation time in addition to the time they spent on their own in the lab. These residents felt this was a meaningful increase in the amount of laparoscopic and hysteroscopic simulation exposure by having access to this in-situ GYN Simulation Training Laboratory with a defined gynecologic curriculum. Multiple staff members also took advantage of the simulation lab to practice their skills as well. CONCLUSIONS: We created an in-situ Gyn Simulation Training Lab that allowed for both improved accessibility by the residents and ease of implementation of simulation curriculum into pre-existing resident didactic time. It is our opinion that the time residents spend engaged in surgical simulation will improve surgical skills and confidence thereby enhancing patient safety. Additionally, the creation of this in situ simulation lab assists in meeting the Accreditation Council for Graduate Medical Education (ACGME) requirements for incorporation of simulation into OB/GYN resident education.

Contraceptive use and childbirth rates by service branch during the first 24 months on active duty in the United States military from 2013 to 2018: a retrospective cohort analysis.

OBJECTIVE: To measure the association of military branch-specific contraceptive education and access policy during basic training with contraceptive use and childbirth among new recruits. STUDY DESIGN: Secondary analysis of insurance records from 92,072 active duty servicewomen who started basic training between 2013 and 2017. RESULTS: Exposure to reproductive health education and access to contraception during basic training differ by military branch. Highly effective contraception use (pills, patch, ring, shot, implants or intrauterine contraception) at 6 months on active duty [Army (18.1%), Air Force (27.4%), Marines (26.5%) and Navy (37.6%), p<.001], long-acting reversible contraceptive method use (implant or intrauterine) at 6 months [Army (2.0%), Air Force (3.7%), Marines (11.0%) and Navy (19.6%), p<.001] and childbirth in the first 24 months of service [Army (11.1%, 95% CI 10.7-11.5), Air Force (6.0%, 95% CI 5.6-6.4), Marines (8.4%, 95% CI 7.8-9.0) and Navy (6.7%, 95% CI 6.3-7.1)] varied by service branch. After adjusting for age at basic training and contraceptive use at 6 months on active duty, childbirth rates differed among all branches. The Army (hazard ratio 1.86, 95% CI 1.71-2.01), Marines (1.48, 95% CI 1.33-1.65) and Navy (1.24, 95% CI 1.13-1.35) all had a higher risk of delivery than the Air Force. CONCLUSION: Variation in branch-specific contraceptive education and access policy during basic training is associated with differences in rates of contraceptive use at 6 months on active duty and childbirth prior to 24 months on active duty. This occurs despite all recruits having access to an identical medical benefit including no-cost access to contraception after completing initial training. Further study is needed to determine the etiology of these differences. IMPLICATIONS: Guidelines for contraceptive education and access during basic training, highly effective contraception use after 6 months of service and childbirth in the first 24 months of service vary among branches of the United States military. Reducing this variability may reduce childbirth rates and improve the reproductive health of junior enlisted servicewomen.

The Dying Art of Vaginal Hysterectomy: A Novel Simulation.

The rate of vaginal hysterectomy has decreased despite the procedure being the preferred hysterectomy method according to the American College of Obstetricians and Gynecologists (ACOG). Physicians have reported that some of the main barriers to performing minimally invasive hysterectomy are the size and shape of the uterus, difficulty of accessibility to the uterus, and surgeons' lack of training and experience. A simulation model for vaginal uterine morcellation was created in an effort to increase surgeons' confidence and to encourage them to select vaginal hysterectomy for their patients. The Conner model, where polyvinyl chloride (PVC) piping is used to simulate the pelvis and vaginal canal, was used as the basis for the pelvis. A medium-density fiberboard (MDF) was used as a base, while a PVC piping structure was used to stimulate the pelvis. The uterus was created from a peanut (car-wash) sponge that was carved into a triangle shape. The reusable MDF/PVC model was built in approximately one hour and cost under USD 30. The sponge uterus was built in approximately 10 minutes and cost under USD 2. Senior residents and faculty who have previously performed uterine morcellation participated in our simulation. Resident physicians reported that they felt more confident in their skills after the simulation. Both resident and staff physicians reported that the model had created a realistic experience. We created a novel model for vaginal uterine morcellation that was reported to be realistic in the initial investigation and increased confidence in the procedure for physicians. The model is easy to create, affordable, and partially reusable.

Measuring Community Prevalence of Trichomonas vaginalis Infection to Guide Local Screening Practices: A Process Improvement Project.

The Centers for Disease Control and Prevention suggests screening for Trichomonas vaginalis infection might be considered in high-prevalence populations. High asymptomatic infection rates and poor sensitivity of clinical diagnosis make it difficult to estimate local prevalence. Testing of ThinPrep samples can provide an estimate of local Trichomonas vaginalis infection rates and guide screening practices.

Postpartum contraception: initiation and effectiveness in a large universal healthcare system.

BACKGROUND: Repeat pregnancies after a short interpregnancy interval are common and are associated with negative maternal and infant health outcomes. Few studies have examined the relative effectiveness of postpartum contraceptive choices. OBJECTIVE: We aimed to determine the initiation trends and relative effectiveness of postpartum contraceptive methods, with typical use, on prevention of short delivery intervals (≤27 months) among women with access to universal healthcare, including coverage that entails no co-payments and allows unlimited contraceptive method switching. STUDY DESIGN: This retrospective cohort study included women who were enrolled in the United States military healthcare system who were admitted for childbirth between October 2010 and March 2015, with ≥6 months postpartum enrollment. With the use of insurance records, we determined the most effective contraceptive method initiated during the first 6 months after delivery, even if subsequently discontinued. Rates of interdelivery intervals of ≤27 months, as proxies for interpregnancy intervals ≤18 months, were determined with the use of the Kaplan-Meier estimator. Women who were disenrolled, who reached 27 months after delivery without another delivery, or who reached the end of the study period were censored. The influence of sociodemographic variables and contraceptive choices on time to subsequent delivery was evaluated by Cox regression analysis, which accounted for a possible correlation among multiple deliveries by an individual woman. RESULTS: During the study timeframe, 373,840 women experienced a total of 450,875 postpartum intervals. Women averaged 27 (standard deviation, 5.3) years of age at the time of delivery; 33.9% of them were <25 years old; 15.5% of them were active duty service members, and 31.6% of them had insurance sponsors of junior enlisted rank (which suggests lower income). Postpartum contraceptive methods that were initiated included self or partner sterilization (7%), intrauterine device (13.5%), etonogestrel implant (3.4%), depot medroxyprogesterone acetate (2.5%), and pill, patch, or ring (36.8%). Furthermore, 36.7% of them did not initiate a prescription method. Etonogestrel implant initiation increased from 1.7% of postpartum women in the first year of our study to 5.3% in the final year. The estimated short interdelivery interval rate was 17.4%, but rates varied with contraceptive method: 1% with sterilization, 6% with long-acting reversible contraception, 12% with depot medroxyprogesterone, 21% with pill, patch, or ring, and 23% with no prescription method. In a multivariable analysis, the adjusted hazard of a short interdelivery interval was highest among women who were younger, on active duty, or with officer insurance sponsors. Compared with nonuse of any prescription contraceptive, the use of an intrauterine device reduced the hazard of a subsequent delivery (adjusted hazard ratio, 0.19; 95% confidence interval, 0.18-0.20), as did etonogestrel implant (adjusted hazard ratio, 0.21; 95% confidence interval, 0.19-0.23); the pill, patch, or ring had less effect (adjusted hazard ratio, 0.80; 95% confidence interval, 0.78-0.81). CONCLUSION: Postpartum initiation of long-acting reversible contraception is highly effective at the prevention of short interdelivery intervals, whereas pill, patch, or ring methods are associated with rates of short interdelivery intervals similar to users of no prescription contraception. This study supports long-acting reversible contraception as first-line recommendations for postpartum women who wish to retain fertility but avoid early repeat pregnancy.

Chorioamniotic Membrane Separation Found on Routine Testing in an Otherwise Asymptomatic Woman With Late Preterm Twin Gestation.

BACKGROUND: Chorioamniotic membrane separation (CMS) is a rare finding that is commonly preceded by invasive fetal procedures. The presence of CMS can also be associated with uncommon maternal or fetal conditions as well as preterm delivery, amniotic band syndrome, umbilical cord complications, and fetal and neonatal death. It is classified as a high-risk antepartum condition due to the significant fetal morbidity and mortality that may ensue. CASE REPORT: A 40-year-old gravida 5 para 1212 at 35 weeks presented for antepartum fetal testing. Her antepartum course was complicated by di-di twin gestation, chronic hypertension, and advanced maternal age. A routine ultrasound (as part of the antepartum fetal testing) identified an incidental finding of CMS. The patient's only reported symptom was that of preterm contractions, without evidence of active labor, and other fetal testing was reassuring. She had a repeat cesarean section that day and the suspected etiology was preterm, premature rupture of membranes of Twin B that was seen on entry into the uterine cavity. DISCUSSION: Chorioamniotic separation is a rare occurrence associated with significant adverse fetal outcomes. This is the first reported case of incidental diagnosis in a twin pregnancy during antepartum fetal surveillance testing. Our detection resulted in the delivery of late preterm, but otherwise healthy, twin neonates.

Complete fetal transection after a motor vehicle collision.

BACKGROUND: Motor vehicle collisions are the leading cause of fetal death related to maternal trauma, with rupture of the gravid uterus being one potential grave outcome. CASE: We present a case of a woman at 22 weeks of gestation who presented to the emergency department after a "high-speed" motor vehicle collision. On initial presentation, she was hemodynamically stable, and the examination was significant for midabdominal transverse ecchymosis from seatbelt trauma. A computed tomography scan identified a probable uterine rupture. Laparotomy revealed a 1,500-mL hemoperitoneum and a completely ruptured uterus requiring hysterectomy. The fetus was completely transected at the level of the midabdomen. CONCLUSION: Uterine rupture is possible for gravid women involved in motor vehicle collisions.

Postoperative activity restrictions: any evidence?

OBJECTIVE: Because of a widespread but untested belief that increased intra-abdominal pressure contributes to pelvic floor disorders, physicians commonly restrict various activities postoperatively. Our aim was to describe intra-abdominal pressures during common physical activities. METHODS: Thirty women of wide age and weight ranges who were not undergoing treatment for pelvic floor disorders performed 3 repetitions of various activities while intra-abdominal pressures (baseline and maximal) were approximated via microtip rectal catheters. We calculated median peak and net pressures (centimeters of H(2)O). We assessed correlations between abdominal pressures and body mass index, abdominal circumference, and grip strength (a proxy for overall strength). P < .025 was considered significant. RESULTS: Median peak abdominal pressures ranged from 48 (lifting 8 lb from a counter) to 150 (lifting 35 lb from the floor), with much variation. Many activities did not raise the intra-abdominal pressure more than simply getting out of a chair, including lifting 8, 13, and 20 lb from a counter, lifting 8 or 13 lb from the floor, climbing stairs, walking briskly, or doing abdominal crunches. Body mass index and abdominal circumference each correlated positively with peak, but not net, pressures. Age and grip strength were not associated with abdominal pressure. CONCLUSION: Some activities commonly restricted postoperatively have no greater effect on intra-abdominal pressures than unavoidable activities like rising from a chair. How lifting is done impacts intra-abdominal pressure. Many current postoperative guidelines are needlessly restrictive. Further research is needed to determine whether increased intra-abdominal pressure truly promotes pelvic floor disorders. LEVEL OF EVIDENCE: III.
